strip foundation for corrugated fence

Today, fencing from corrugated board is very popular. To make the fence reliable and look solid, they usually make a tape for it foundation for a fence with brick columns. It prevents rain water from flowing and street animals will not be able to penetrate the site.

When designing a foundation, many details must be considered. First, determine the size and study the area of the proposed construction. If the site is not even and there are significant differences, then it is more rational to break the foundation into steps. But this is if the differences are significant, with a length of 10 meters the level difference is more than half a meter.

The width can be chosen the same as for brick supports. But in order to save thickness, you can make different. Full, under the posts and narrow under the corrugated tape. Of course, this will complicate the arrangement of the formwork, but it will reduce the amount of earthwork and concrete consumption.

The depth of the foundation also varies. Under the pillars, it should be more, not less than a meter and not higher than the level of freezing of the soil. This will guarantee that the foundation will be fixed, which means that the gate and gate will work reliably. They are fastened by welding to pipes mounted in brick supports using embedded parts.

It should also be borne in mind that at different depths of laying the foundation, the buoyancy force of the soil in individual areas will be different. Therefore, in this case, connecting the foundation into one structure is not necessary. In frost, under the influence of heaving forces, this will lead to deformation of individual sections of the foundation tape. This is especially dangerous for poles on which gates will be mounted.

In order to effectively protect against heaving forces that will push the foundation tape out of the ground with lateral friction, it is necessary to fill the foundation so that the bottom is wider than the top.

Also, when designing, it is necessary to carry out material calculations. The depth of freezing in each region is different, therefore, the consumption of material will vary. In order for the foundation to be stable, it is necessary to calculate the optimal proportion so that the structure does not precipitate. The calculation is performed according to the formula (k (n) * F) / (k (c) * R).
Where (k (n) is the coefficient of reliability, (k (c) is the coefficient of working conditions, R is the soil resistance, F is the calculation of the load on the soil base.
