How to make a foundation of asbestos-cement pipes?

The foundation of asbestos-cement pipes can be constructed independently, but before starting the work it is necessary to consider all the features of this type of substrate, as well as to learn in detail about the process technology. This type of foundation acts as a successful alternative to a tape, monolithic or slab base. Such a foundation, as a rule, is used in the construction of insignificant in weight structures. In addition, the work will not be accompanied by too much cost. It should be noted that this type of foundation is almost indispensable when it comes to frame houses or utility buildings. But we can not ignore the fact that he has certain disadvantages, one of which is expressed in the fact that the building can not have a basement or basement room.

Features of construction

The foundation of asbestos-cement pipes does not imply the use of heavy equipment. The foundation, in which the supports, can be made in one of two ways. The first involves the use of ready-made piles. But in private housing construction this method is of little use, which is due to the need to rent specialized equipment. The second method involves the production of poles directly in the soil. In this case, the solution must be poured into the formwork, which is formed in a previously dug hole in the ground. In the role of formwork, all kinds of structures are used, among which there may be wooden shields.

The foundation of asbestos-cement pipes is quite easy to equip because the pipes used in the form of the formwork have very little weight. Using such products, you get a guarantee that the concrete will not be exposed to water. In addition, the supports are not afraid of external damage, because the asbestos-cement pipes have a fairly impressive margin of safety. All these qualities make them ideal for the construction of fixed formwork. Choose for the construction of pipes of the desired diameter.

The foundation of asbestos-cement pipes can be erected on the territory, which differs uneven terrain. Moreover, a high percentage of soil moisture is allowed. It is important to take into account the weight of the future structure before starting construction, since with an impressive mass the number of supports should be increased.

Foundation technology

Initially, it is necessary to make all calculations, the implementation of which is more preferable to entrust to professionals. When determining the number of poles, it is necessary to take into account the fact that the largest step between supports should not be more than 2.5 m. The next step is to proceed to the preparation of the territory on which construction will be carried out. The soil must be free of debris and foreign objects. From the fertile layer of soil to be disposed of. After that, the land, as a rule, is transferred to another part of the site, so that it does not act as an obstacle to the work.

Before making a foundation of asbestos-cement pipes, it is necessary to make a basement marking. It is important to check how well the corners are laid out, for which you will have to pull a fishing line or a special marking cord. It is necessary to do this not only on the sides of the base, but also on the diagonals, while it is important to ensure that the ideal rectangle has turned out. Only after this, it is possible to start work on drilling wells, into which the supports will be installed.

In order to equip the columnar foundation of asbestos-cement pipes, it is necessary to prepare wells that are drilled through a garden drill, but a TISE tool can also be used. If it is supposed to produce work in a territory with complex soils, then it is worth using a drilling rig, which will have to be rented. It should be remembered that such an approach will increase the cost of work. Deepen the supports below the freezing line of the soil.

PILLOW DEVICE

Before installing asbestos-cement pipes under the foundation, it is necessary to prepare the bottom of the well, for which a sand cushion is filled there. It is necessary to pour so much that after tamping a layer with a thickness of approximately 20 cm is obtained. It is necessary to spill it with water to make the pillow easier to ram. If the work is carried out on excessively weak soils, a concrete support can be created at the bottom of the well, but its diameter should be somewhat wider than that characteristic of the asbestos-cement pipe. In order to provide insulation, it is recommended to cover a layer of dense polyethylene at the bottom of the well, this will make it possible to exclude the possibility of moisture release into the soil from the concrete solution.

Installation of pipes

When you mount the foundation on asbestos-cement pipes with your own hands, then the next step is to proceed with the installation of asbestos-cement pipes. To install the element it is necessary strictly in the vertical position, for this purpose it is necessary to use spacers. It is necessary to analyze the smoothness of the installation of pipes, using the building level for this.

Reinforcement

The support must necessarily be reinforced, for this purpose it is necessary to prepare the reinforcing frame from the rods beforehand. Horizontal and vertical belts are required. After the reinforcement can be lowered into the pipe. If it is intended to build a horizontal strapping, the reinforcing bars must be pushed out to connect to the grill bar.

Pouring concrete

After that, you can proceed to pouring, you need to do this layer by layer, so that you can eliminate the air. The space between the pipe and the well should be filled with sand and carefully compacted. The upper part of the pipe must be cut to the level, then you can start installing the head and laying the waterproofing. If it is assumed that there is a grillage, then the next step is to deal with them.
