Soft soil foundation treatment reinforcement method and device thereof

Abstract

The invention relates to a soft soil foundation treatment reinforcement method which is characterized by comprises the following steps: a layer of grid-shaped bamboo raft with geotechnological weavedcloth below is paved on the surface layer of the soft soil; after the bamboo raft with the geotechnological cloth is paved, bamboos with certain length are inserted into the soft soil along the frameof the bamboo raft, wherein the upper ends of the bamboos are tightly and fixedly connected with the bamboo raft, so that the bamboo raft to be hammered into a soft soil layer, in a frame shape; the frame-shaped bamboo raft is firstly taken as a work cushion for the soft soil foundation treatment; a layer of geotechnological cloth, a horizontal drainage body and a sand stone layer are arranged atthe upper side of the work cushion in sequence from bottom to top, wherein the horizontal drainage body is buried with a horizontal drainage pipe and a vertical drainage body which is inserted into the soft soil layer so as to conduct soft soil drainage consolidation treatment; and the sand stone layer consists of medium-coarse sand or rubble, gravel. The soft soil foundation treatment reinforcement method has the advantages of short foundation treatment period, uneven settlement resistance, good compressive stress diffusion effect, less post-construction settlement, high bearing capacity, lowcost, environmental protection, energy conservation, realization of renewable resources and the like.

Description

technical field [0001] The invention relates to a new reinforcement technology for the treatment of saturated soft soil and extremely soft soil foundation. It is the work of connecting the grid-shaped round moso bamboo row with the round moso bamboo directly inserted into the soft soil to form a frame and reinforce it in the reinforced soft soil, first as the foundation treatment of soft soil (especially very soft soil) Cushion layer, so that the follow-up procedures of foundation treatment such as installation of horizontal drainage body and vertical drainage body, vacuum preloading or surcharge preloading, and dynamic drainage consolidation can be carried out quickly; when performing drainage consolidation treatment on soft soil, along with The soft soil is consolidated and settled, and the frame-shaped bamboo raft is firmly nailed in the soft soil body as a reinforced structure and is tightly combined with the soft soil body, and is tightly combined with the compacted upper...

AI Technical Summary

Problems solved by technology

[0006] In the conventional foundation treatment process, the upper filling soil and the underlying soft soil are loosely combined after treatment, resulting in poor integrity and low compressive stress diffusion effect
