Soft soil foundation rainwater infiltration promotion system and construction method thereof
The invention relates to the technical field of municipal engineering and architectural engineering and provides a soft soil foundation rainwater infiltration promotion system and a construction method thereof so as to solve the problem that an existing urban rainwater runoff source control method is not applicable to a soft soil foundation where the underground water level is high and the soil infiltration coefficient is small. The soft soil foundation rainwater infiltration promotion system comprises a plurality of infiltration promotion piles which are vertically arranged in a soil layer of the soft soil foundation. The top end of each infiltration promotion pile is provided with a plurality of strip-shaped infiltration trenches with the gradient. The bottom ends of the strip-shaped infiltration trenches converge at the top ends of the infiltration promotion piles. The construction method comprises the first step of preparing the infiltration promotion piles, the second step of punching a plurality of pile holes in the soil layer of the soft soil foundation, sinking sleeves into the pile holes by a preset depth, placing the infiltration promotion piles into the sleeves and sinking the infiltration promotion piles to the bottoms of the sleeves, and the third step of pulling the sleeves upwards, excavating a plurality of trenches in the top ends of the infiltration promotion piles, constructing the strip-shaped infiltration trenches with the gradient along the trenches and making the convergence positions of the strip-shaped infiltration trenches located at the top ends of the infiltration promotion piles.
