We should have a certain understanding of fir piles, we can see them in many places. It will also be used in the construction of soft soil foundations. Next, the editor will take you to understand how to use fir piles in construction.

Practice has proved that fir piles are convenient to construct and can avoid large amounts of earth excavation in soft soil foundation treatment. Therefore, fir piles are economically and technically feasible in soft soil foundation treatment in areas with abundant fir pile resources. They are the best choice for soft soil foundation treatment. effective method.

The application of fir piles in soft soil foundations is based on the practical experience of soft soil foundation engineering construction and design. In engineering geological surveys and geotechnical engineering tests, only through the investigation of soil conditions can the design and construction be carried out correctly. The characteristics of the foundation soil consider the foundation, structure, construction and use of the foundation.

Generally speaking, when the thickness of soft soil is less than 5 meters, fir piles should be used, and the pile length should not exceed 4 meters. When used as end-bearing piles, in order to ensure the load-bearing layer, the pile ends can enter the upper part and dig into the deep foundation, because Fir is rich in resin, which can avoid corrosion by groundwater and bacteria, and is relatively cheap.

An ecological revetment fir pile is provided to purify surface runoff pollution of landscape lakes. The ecological revetment can intercept and purify surface runoff pollution, thereby controlling and protecting lake water quality.

In the 2-habitat interweaving zone (water area), there is a low wall slope at the bottom of the building. There is a purification ditch in the slope zone and the pectin intertwined zone. The overflow dam purification ditch is located at the junction of the slope zone and the 2-habitat intertwined zone.

When part of the surface runoff passes through the ditch, due to the change in the direction of the water flow and the obstruction of the overflow weir, most of the soil particles and solid impurities in the water are intercepted by the ditch. The water flowing through the overflow weir continues along the surface of the land-water interweaving zone Flow downward. Because of the shielding effect of the geotextile, the soil will not be corroded by the water flow.

The slope foot can be made of natural stone slurry, with the lower part extending below the ground, and a concrete foundation set at the bottom. The slope foot can support objects on the slope protection to prevent the slope from sliding down. The geotextile can be extended to cover the inner and outer surfaces of the slope foot (land-water interweaving zone side) to complete the protection of the slope foot and the fixation of the geotextile.
