Shallow soft soil composite reinforcing structure and method for reinforcing shallow soft soil foundation

Abstract

The invention discloses a shallow soft soil composite reinforcing structure which comprises a frame type reinforcing body, the frame type reinforcing body is composed of a plurality of reinforcing filtering bodies with tips, filtering holes are distributed in the reinforcing filtering bodies, the inner sides of the reinforcing filtering bodies are covered with filtering cloth, and the upper end of the frame type reinforcing body is connected and reinforced through frame rods. A water pumping pipe is inserted into the reinforced filtering body from top to bottom, the lower part of the water pumping pipe is provided with a water inlet hole, the water pumping pipe 4 is connected with a water pump through a pipeline, and a sunken area on the upper side of the reinforced filtering body is filled with permeable particles. According to the structure and the method, water in the soil body can be rapidly discharged and directly combined with the soil body to form a reinforced structure.

Description

technical field [0001] The invention relates to the field of shallow weak soil reinforcement, in particular to a composite reinforcement structure for shallow weak soil. The present invention also relates to a method for reinforcing shallow soft soil foundations using the composite reinforcement structure for shallow weak soil. Background technique [0002] The soft soil gene has high water content and poor soil bearing capacity. Therefore, to construct on the soft soil foundation, the soft soil foundation must first be strengthened. The traditional foundation treatment methods include replacement of cushions, pre-compression drainage and consolidation. method, composite foundation method, chemical reinforcement method, etc. Among them, the composite foundation method includes sand piles, vibrating (or sinking pipe) gravel piles, lime soil piles, etc., the large-area treatment costs are relatively high, and the construction period is relatively long, which cannot meet the r...

AI Technical Summary

Problems solved by technology

Among them, the composite foundation method includes sand piles, vibrating (or sinking pipe) gravel piles, lime soil piles, etc., the large-area treatment costs are relatively high, and the construction period is relatively long, which cannot meet the requirements of project cost and construction period; chemical reinforcement methods include Grouting method, jet grouting method, deep mixing method, etc. are generally expensive and easy to pollute the soil; pre-pressing drainage consolidation method is a relatively cheap and effective reinforcement measure, but the construction is cumbersome and the construction period is too long
