Foundations of asbestos-cement pipes: basics of construction

Advantages of the

foundation The most suitable for the small footage buildings is the foundation of the asbestos-cement pipe , on which there will not be a lot of pressure on the upper floors and the like. It is distinguished by economy and benefits unlike other types of foundation. Installed on any land, hard and puchinistyh primer. Installation is made on the principle of pillars( pipes), and wooden "chairs" placed at a certain distance from each other. The foundation has a major advantage over others - it is the anti-corrosion properties of the metal. And asbestos-cement pipes are cheaper than other foundation pipes.

The advantages of asbestos-cement pipes are:

1. Not susceptible to corrosion and rot.
2. Cheapness.
3. Easy to install and work with( cut with a hacksaw or saw).
4. Durability of all kinds to the environment.

All mentioned makes these pipes the most popular for the construction of small-sized buildings.

Asbestos-cement pipe pillar foundation:

features The foundation is set, when at a depth of 2-3 the void is a hard ground. If they are deeper than the indicated footage, then use tape.

To make it more clear, in the photo below, a columnar foundation.

It is presented in the form of supports from asbestos-cement pipes having a diameter of 200 mm, bricks, reinforced concrete, concrete and concrete, etc.

Each pole is installed on the angular section of the walls and at the junction of internal and external partitions. Between the posts there should be a distance not exceeding the length of the log. Therefore, if the house is built of wood, you should follow this. This distance is called a vial. It is not stacked with brick and concrete, so that in case of punching they do not violate the state of the foundation of the entire structure.

Calculation of the foundation from asbestos-cement pipes

Procedure:

1. Calculation of the number of poles.
2. Exploration of the characteristics of the soil on construction and the availability of groundwater in its territory.
3. Information on the degree of freezing in the winter.
4. The calculation of the dimensions of the building and its approximate weight.

The global calculation of the depth of the columnar foundation is based on what materials will be used.

The number of posts should be such that it can evenly distribute the weight of the building along the entire perimeter. Above the ground, the poles are mostly up to half a meter, but if there is a threat of floods on the ground, their height increases until there are significant water fillings. Information about this can be learned from local residents.

Preparation of

If you have chosen asbestos-cement pipes for the foundation, then you must take care of the construction site. The site for construction is determined by 3 meters more than the marking of the building itself.

The whole territory is removed from garbage, bushes, trees, and the top layer of the land is removed by 20 cm and placed in the garden or garden part of the plot.

When the preparation is done, mark out the foundation according to the architectural design. For clarity, pegs are driven into the corners and a string or rope is stretched between them.

Pipe installation

Pile foundation from asbestos pipes during installation means the use of a drilling machine or a garden drill. The well is drilled to the required size, determined in advance.

Sand is poured into the well up to 20-30 cm. And an asbestos pipe is placed on it.

1. Attach the pipe with spacers to make it stand flat. For reliability, you can even insert the reinforcement in the middle. It also enshrined that when the asbestos pipe was filled with concrete, the reinforcement did not move.
2. The armature should protrude at a distance of up to half a meter, so that after it has become the basis for a fundamental beam or beam.
3. Concrete is harvested at the factory or prepared on site by yourself. Then pour into the pipes. And for 28 days the concrete should stand immovably, that it completely hardens and becomes 100% strong. But for the reason that the asbestos tube itself is strong, the next list of works with the structure can be done in 2 weeks.
4. As soon as the concrete poles become fully solid, their upper part is leveled to one level, using the building level.
5. After leveling, they begin to build a bandage of reinforced concrete and beams depending on the main material of the walls. Can be used as factory, and handmade foundation reinforced concrete beams.

The foundation is installed, and you can lay the first brick of a new house!
