Construction methods of sand piles in the treatment of the foundation of the house

Sand pits are a part of the structural foundation of the house responsible for receiving and transmitting the load to the ground. Weak ground will be reinforced by a network of sand piles known as sand piles. This type of platform will bring some benefits and have certain construction methods. Together we learn about the construction characteristics of this type.

Sand pits function as a sand well that causes water in the soil to escape quickly through the sand hole. The consolidation and growth process will be accelerated and accelerated due to land treatment. The steel is plugged into the ground to make the platform tight. The soil is further compressed by the process of making holes. The water in the soil will be compressed into the hole drilled sand.

As a result, the ground is made of high strength after the treatment. It is also very simple to perform the ground treatment with this type of pile. Leaf material is quite inexpensive so the cost is also more economical to use other materials. Weak ground of 3 meters in length should use this type of pile to treat the foundation.

Effect of sand piles

Construction of this type is simple and relatively cheap material from gravel or rough sand, so the cost is relatively lower than cushion sand, the type of concrete foundation, the type used to treat other soil. This product is used to reinforce the weak soil more than 3 meters.

The width of the soil is reduced due to the compacted soil, so that the strength of the pile is improved. Helping pairs of pairs helps the voids in the soil escape faster for faster consolidation of the soil, the settling is reduced and more stable.

Note when installing sand piles

There is a note that it is not advisable to use sand piles in soils that are too dense (at the compression factor). Sand piles are not capable of compacting and are not suitable for weak soils that are less than 2m thick. For compacted sand piles, the soil must be reclaimed with high tensile strength by vibration energy to compact the sand in boreholes with a diameter of 60 to 80 cm.

With regular piles, this is a typical upstream vertical discharge for consolidation after 40cm borehole. Mineral is a major component and has high conductivity that can replace sand. Use compressed equipment and then put steel pipes in the soil then pour sand into.

Generally, sand piles are used to reinforce weak earths over 3m thick. Its advantages are also relatively high and the construction problem is not too complicated. However, if the construction contractor does not have the equipment, it can not be constructed or handled.
