Soil-bentonite vertical diaphragm wall and construction method thereof
The invention relates to a soil-bentonite vertical diaphragm wall and a construction method thereof. Original stratum soil produced in the trench digging process is doped with bentonite powder, the mixture and bentonite mud of a dado groove are mixed to form homogeneous materials similar to concrete mortar, and the soil-bentonite vertical diaphragm wall is formed in a dead load solidification mode, wherein the dry weight ratio of the bentonite powder to the original stratum soil is 3-5 percent; the content of montmorillonite of the bentonite is equal to or larger than 50 percent, the expansion index ranges from 25 ml/2g to 40 ml/2g, and the cation exchange capacity is larger than 120 mmol/100g. The original stratum soil produced in the trench digging process is doped with the bentonite powder, the mixture and the bentonite mud of the dado groove are mixed to form the homogeneous materials similar to the concrete mortar, and the physical property of the wall materials, the dry weight ratio of the bentonite powder to the original stratum soil and the physicochemical property of the bentonite are accurately controlled, the effects that the porosity of the vertical diaphragm wall is low and the seepage-proofing performance is good are achieved, and the project cost can be notably reduced.
