Embodiment Construction

[0019] refer to figure 1 , figure 2 with image 3 Before the foundation treatment of the soft soil, lay a layer of round moso bamboo rafts with geotechnical woven cloth mesh under the surface of the soft soil, and insert a certain length of round moso bamboo into the soft soil layer and the plane grid-like bamboo row tightly Solid connection, so that the bamboo rafts extend into the soft soil layer in a frame shape. The frame-shaped bamboo raft is firstly used as a working cushion for soft soil (especially extremely soft soil); and then when the underlying soft soil is drained and consolidated after filling the bamboo raft, the frame-shaped bamboo raft will consolidate and settle as the soft soil settles. Bamboo rafts are firmly nailed in the lower soft soil as a reinforced structure and tightly combined with the soft soil, and are tightly combined with the compacted upper fill to form a reinforced valve plate-shaped consolidated soil, so that the treated lower soft soil A...

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...
