Plastic rings for the well, the types and characteristics

New technologies in human life can only be considered valid when they have more energy-efficient and eco-friendly qualities than the previous ones. Practically proved its right to exist plastic rings for wells. They displace heavy concrete structures, the installation of which is time-consuming and very costly. Products have simplified the process of arrangement of the wells, and the operation to make a reliable and affordable.

The diversity of the wells and area of ​​application

Plastic rings for wells firmly and securely entered into various spheres of human activity. Mounted ones wells provide the production and consumption need. Based on the characteristics of the target destination, the wells can be divided into the following types:

• classical. It is a source of drinking water. Traditionally, water is supplied by a pump or pumping station;

• cesspit. Mounted in the absence of sewerage. At the bottom of the set will throw at him the way out waste water;
• drain (absorption). This kind of manhole, only without the throw. At the bottom layer of poured sand or gravel;
• storage. It serves to collect water, often rain, which can be used for irrigation or other purposes;
• telecommunications. Designed to accommodate the couplings and pilings stock optical fiber and power cable. Is set as a pedestrian, and the transport zone;
• viewing. Designed to monitor and repair sewer systems. It mounted the stairs, handrails and other fixtures to omit to perform repair and maintenance work;
• septic tank. Special purification plant where waste water is processed in a decanter. underground filtration system produces decomposition without oxygen.

Useful advice! To quickly and correctly select the appropriate version of the plastic well, it is better to take advantage of the finished configuration.

Large plastic pipes diameter as an alternative to concrete structures

The advent of plastic rings for wells was already a serious competition, it would seem, the waste and the most advanced technology of laying concrete structures. Comparing functions, labor costs and the final price of the plastic wells, we conclude, that the advantages of the latter are obvious.

Weight polyethylene ring with an internal diameter of 900 mm, a height of 2 m and a wall thickness of 25 mm - 46 kg. A ring of reinforced concrete with an inner radius of 1000 mm, a wall thickness of 80 mm and a height of 890 mm weighing 600 kg. This weight naturally cause difficulties in transporting and stacking.

Compounds via thread entering the groove and silicone gasket create almost maximum tightness modular plastic pipe. The seams between the concrete rings are sealed by the cement slurry, which eventually collapses.

Plastic rings are easily cut. They can be made according to individual sizes. Concrete are available only in standard sizes, they are not subject to change.

The presence of pores and cavities in the concrete rings promotes an environment for bacterial growth. The inner side of the plastic ring is absolutely smooth, the presence of bacteria on the walls is possible.

Negative attitudes towards the installation of plastic wells from environmental supporters not observed. Such designs have good functionality and have the characteristics corresponding to modern requirements of health and safety.

The main features of the plastic wells:

• not subject to corrosion;
• resistant to vibration and other mechanical influences;
• hardy, tolerate extremes of temperature;
• have a rigid structure;
• do not require additional treatment;
• sealed in tubes input field;
• quick to install;
• safe for the environment.

Important information! The price of plastic rings for sewage significantly higher than concrete. But given the cost of transportation and installation of the latter, the total cost of wells obtained by virtually equivalent.

Material: characteristics of the polymers used

Rings for wells (sewer, switching to drinking water and a septic tank) routinely refer to one word - "plastic". Because of this material wells are used for various industrial purposes, in everyday life, to create drainage systems, as they operate in different soil and at different mechanical and thermal stresses, it is made different from their polymers.

For the manufacture of plastic manhole rings used:

• PVC;
• polyethylene;
• polypropylene;
• polymer-sand mixture.

Despite the overall high operational performance, materials are still a number of features vary. The wells of PVC fire resistant. This material is resistant to various chemicals. Polyethylene product is best transferred to temperature changes, freezing and thawing water does not deform the ring.

Polypropylene is used for installation in locations where there is a constant mechanical vibration or impact on the structure. Plastic material and most durable. Polymeric sand pit is characterized by almost absolute integrity.

Useful advice!When choosing a ring for a plastic well, be sure to pay attention to the production of material and compares it with the quality of the terms of use and purpose of the well.

For drinking water wells, in the absence of the problem of ground can fly Polyethylene ring. They are inexpensive and well suited for functional features. If the soil is unfavorable, it is worth to buy a well Polymer.

For switching of the well, which is subject to constant mechanical stress (for example, calls in traveling or parked car), it is better to buy a ring of PVC. Their price is the highest, but this material without consequences withstand permanent loads.

To buy septic rings are inexpensive polyethylene. Flatulence does not deform and does not negatively affect the state of the polymer. Costs for the purchase of more wear-resistant material is superfluous.

Growing demand is provided by selecting proposals. Today, plastic rings for the well can be bought in any store that sells sanitary equipment and products made from plastic. Select the pipe from the desired material is not difficult.

Plastic rings for wells: sizes and methods of compound

Dimensions of manhole rings are different. Key indicators - the diameter, height and thickness. The diameter of the rings varies from 400 to 1500 mm. Keep in mind that it should be 10 - 15 cm less than the diameter of the prepared shaft.

Height - a second component on which the ring should be selected. This count value is necessary, starting from a depth of future wells. Typical dimensions of the height of the Rings - 500, 1000, 1500 mm.

The wall thickness is on average 55 mm (in certain types of polyethylene have a ring size of 6, 8, 22 mm). The outer diameter of the rings ranges from 455 to 1555 mm. That size makes available capacity and installation of plastic products.

For drinking arrangement well advisable to choose the diameter of the ring 680, 800 and 900 mm. For sewage, drainage wells and switching systems - 800, 900, 1500 mm.

Useful advice! The deeper the mine of the future of the well, the thicker should be the ring.

Collect the rings into a single structure complexity is not. This process does not take much time and does not require significant preparation and a large number of participants. Compound rings by three main ways:

• twisting of the thread;
• hit and snap into the groove;
• welding.

When properly executed technologically installing all kinds of connections provide a high degree of integrity. The first two methods recommended to perform using silicone sealants. Welding requires no additional equipment.

Used when creating wells and one-piece plastic ring. They actively apply for the restoration of old concrete wells, which can not be removed.

Such articles are also used for septic device. The advantages of non-separable rings are:

• thickness of 6 mm (necessary are available);
• It can reach a height of 5 m (which greatly simplifies the installation);
• begins with a diameter of 95 mm (it allows to equip well).

Useful advice! When buying plastic rings for the well it is necessary to examine their inner and outer surfaces. Uniform color of individual sections may indicate a violation of the density or the presence of the strain.

Requirements for the placement of the plastic wells for water supply

Construction of the plastic wells, as well as any other project, should begin with planning. If the well is drinking, be sure to know how deep is the water reservoir and where it is most close to the surface. This will save the physical and material costs to the device and make it more convenient use of the well in the future.

Varieties of rings. Selection of the pump. The construction of the well, the choice of location, installation instructions.

Writing such information can only gidrogeodeziya portion. Organizations having a license for such work is enough. The order runs for three days (taking into account the preparation of the report-report).

In addition to information about the short depth of the water reservoir, such works also give information about the quality of the soil. Depending on the results you can choose the place of the mine and preparation method of installation.

Useful advice! When choosing the location of the well to avoid close-growing trees. Roots can damage the walls of the device.

The dimensions of large diameter plastic pipes for drinking water wells are selected based on the fact that at least 50 cm, they must have a higher surface area. This will prevent ingress into the pit of rain and melt water. For other types of devices, this condition is not necessary, as in their design includes closing the hatch.

Space requirementsplastic wells for sewage

Determine the position of manhole, it is necessary to know if a close friend of communication routed so as not to damage them during the preparation of the mine. It is necessary to remove the well from growing trees for at least two meters. sewage system elements must be positioned at a distance of 1.5 m from the water pipes.

Cesspit should be within 10 meters from the exit of the waste stream is removed from the building and not less than 3 meters. It is better to buy a plastic ring for the purpose of sewage wells with a diameter of at least 900 mm. This size makes it accessible for repair and revision work.

Purchase of materials and methods for stacking plastic rings

Only after studying the technical specifications and the preparation of project component can proceed to the purchase of materials. Purchase components needed, based on the required depth of the well, considering the possible or desired diameter. be sure to take into account the subsequent operation when determining the size.

Useful advice! If there is uncertainty about the correctness of the preparatory phase, it is best to contact the organization dedicated to the installation of plastic wells, for drawing up the plan and budget. Even minor errors can lead to the inability of normal operation of the device in future.

Plastic rings septic optionally choose costly. Quite enough polyethylene (they are the cheapest) of medium thickness (20-30 mm). Plastic Drain well buy the best of the more resistant material - polypropylene, as it is likely to be located in a place where unavoidable external loads.

Depending on the composition and layers of soil mobility style rings can be open or closed method.

Open method is used, if the ground is different friability, mobility. Excavated mine the required depth, having a size of 10-15 cm longer than the diameter of the rings. If the drinking water well, laid out on the bottom of the filter sand, pebbles or geotextile. The apparatus sewage pit or other purposes, the appropriate tray:

• solid;
• with profiling in the form of grooves;
• distribution;
• pass.

From individual plastic rings going pipe and lowered into the well shaft. The tube is leveled, and the space between the plastic and the ground is filled with small pebbles, sand or a mixture thereof. Mounted spout, set hatch.

Useful advice! You do not need to fill in the space with cement mortar. This greatly complicates the repair or reconstruction of the well in the future.

Indoor installation method is appropriate wells where loose soil. Digging to a depth of one shaft ring which is subsequently determined. Then, primer is chosen so that ring sinking under its own weight. To use this method, it is important that the connection method of the Rings was simple - thread or groove. After laying all the necessary tubing is filled the bottom of sand, pebbles or grout. Further filled space between the ground and mine walls mounted hatch.

Types standard manholes plastic wells

An important condition for long-term and proper functioning of the well is the correct selection of the hatch. The basis of the standards laid down load that can be expected to withstand the plastic Kolodeznaya design. Different hatches to withstand load:

1. Up to 1.5 tons. They are used in areas where no permanent mechanical pressure. This can be walking paths, lawns, lawns.
2. To 12.5 tons. Installed on the sidewalks, in parking areas of transportation.
3. Up to 25 tons. Designed for installation on urban roads.
4. Up to 40 tons. Withstand the load of constant traffic flow, including trucks. Placed on motorways.

Depending on the set of the well components hatches set:

• directly with the shaft;
• on the neck;
• on the torque ring.

Directly on the shaft can be put only hatches to withstand loads up to 1.5 tonnes. For other kinds of applicable any installation method. When installing the well should be borne in mind that the weight that can withstand the cover must correspond to the thickness of the plastic rings for sewage.

The size and price of plastic rings for sewage

Prices of plastic rings for the well depend mostly on the size and quality of the polymer used. Certain impact on the cost are also the manufacturer and place of manufacture. The most accessible rings are polyethylene. More expensive will be the construction of PVC.

Sales leader - a ring of polypropylene. They have a reasonable price and high technical performance. They are used for everything virtually all types of wells.

Below are the pricing tables sewer rings of the two types of polymers.

Useful advice! Price rings in the well of the bulk of the amount of costly, but in the planning of material investments in advance should take into account the cost of hatches, neck tees, cones and other specific elements of plastic wells. As a result, the costs can be considerable.

One of the most popular products are considered to be domestic company "Ecosystem". The manufacturer sells the plastic ring on the following principle: outer diameter - 950 mm, internal - 900 mm, height - 1500 mm, the price - 9 ths. rub.; External diameter - 600 mm, internal - 650 mm Height - 1500 mm, the price - 8 thousand. rub.

Another leading company in the production of plastic water supply, sewerage and communications is Rodlex. She sells plastic rings at a price: the height of 500 mm - 4320 rubles.; height 1000 mm - 8640 rubles.; height 1500 mm - 12900 rub.; height 3000 mm - 25900 rubles. The drawer need to pay 3-4 thousand.

Manufactures prefabricated plastic manholes and capital FDplast plant. It offers design, which consist of a tray, the mine, the neck, the telescopic tube and a compact hatch. Products are competitive plant. The average price, a guaranteed shelf life of products - 50 years, portable temperature - from -60 to 70 degrees. The tightness is achieved with the help of adapters and O-rings.

The average price of plastic pipes of large diameter domestic producers - 9000 rubles (standard five-foot model). Construction with the tray stand at 3-4 thousand expensive. Plain shaft with the bottom will cost 12-13 thousand. Caps and other system components must be purchased separately and are not included as standard. Their value depends on the shape and material. The average price for round and square cover - 2-3 thousand rubles.

Among foreign manufacturers popular company Wavin. It produces inspection and storm types of modular systems made of plastic. All Wavin company products are of high performance and good resistance to mechanical damage. Prices for the products of the company are different from domestic to 3-7%. Line items are more expensive, but there are a considerable number of products which have a lower cost. For more information, visit the company's website.

Features of carrying out repair and maintenance work

Drinking concrete wells (even at a constant cleaning) in 25-30 years in need of major repair or replacement. With the advent of the repair of plastic rings became less problematic. It's about a new plastic wells for drinking water in place of old concrete.

Signs pointing to the need for well replacement of concrete, can be considered:

• appearance of water or moisture malodor rot;

• presence of clay impurities (water became turbid);
• critical reduction of the water level;
• extensive destruction of concrete rings.

Choose rings for repairs needed, keeping the requirements, they will be less concrete by 10-15 cm. The remaining concrete vault is a definite obstacle to the action of moving the soil. Given that the ring of concrete will continue to deteriorate and may exacerbate effects of soil material plastic rings to update the well should be selected durable, wear-resistant.

The assembled tube is lowered into concrete, the gap is filled with a mixture of sand and pebbles. In the presence of intense groundwater and leaks in the old design point of connection rings desirable to further seal with silicone.

It is important! Purification bottom and replacement of the filter layer must be done before the lowering into the shaft of the plastic pipe. Otherwise, replace the bottom will only partially, that is required to affect the quality of water treatment.

Still preserved a sufficient number of wells, wherein the shaft is formed with the help of brickwork. It usually has a rectangular or square shape. Such designs are commonly used for telecommunication networks, so they are shallow.

If the well dimensions allow, it can be restored by plastic rings, following a specific sequence of performance of works:

• remove the hatch;
• parse topsheet masonry;
• well clear of the collapsed debris;
• mount and lower rings assembled from pipe (with the switching of channels);
• to fill the voids between the brick walls and the tube;
• establish an appropriate way the new hatch.

Possible repair of wells with the use of one-piece construction. The main advantage is that it is completely sealed. In this way, it is advisable to repair shallow wells - up to 500 cm. The bottom edge should be installed on a flat surface. When deciding on the repair or installation of the well via one piece construction, it is necessary to take into account the thickness of the tube and compare it to the load.

Plastic well with their hands

Under appropriate conditions (water is relatively close to the surface neproblemny ground) the well can be done independently. If you need a shallow pit (up to 1 m), it is possible to dig by hand. If the water is deeper, it is necessary to use a drill. At considerable depth nozzles need for it. The optimum diameter of rings used - 40 cm. Pipe to collect, visually verify the tightness of joints.

Then proceed as many holes in the lower part at a distance of 50 cm from the bottom edge, 10 mm using a drill. Perforated area be sure to wrap a mesh made of synthetic materials that can not be exposed to water. She will perform the filter functions. The gap between the plastic and the ground should be covered with sand.

Useful advice! In order to avoid unnecessary costs or the need to purchase additional rings, the purchase of their best to do after the training of the mine.

Rules and tips for operating the wells of plastic

Plastic wells do not require constant monitoring of the state of the complex during the operation. The inner surface of the ring is smooth, so the walls only after a long period of time may appear rainfall. Cleaning does not cause problems: brush, broom, high pressure water jet will remove plaque. If the joints in the assembly are properly connected and sealed, then before the end of service life (50 years), no cracks will appear.

If necessary, add a ring (for example, in the case of subsidence) must be removed first in order to free access to the thread. To this effect did not result in damage to components, they should be easily removable (not cemented).

Part of the plastic wells, located above the surface, it is better to close. Direct sunlight can cause deformation of rings, especially when they have a small thickness. You can simulate the frame if it is drinking well. Masonry will give an aesthetic appearance. The original canopy to protect from the sun and will design element portion, which is situated.

Wells of plastic rings have become a significant step forward in the field of rational and reasonable improvement of household and industrial conditions. A viable alternative to them today did not exist. Size design, accessibility installation in any location, high technology, long service life make them the only reliable way to ensure the proper functioning of water, wastewater and other communications.
