METHOD OF SOLIDIFYING SURFACE OF SOFT GROUND WITH PREVENTING PARTICLE OF SOLIDIFYING AGENT FROM FLYING AND BEING SCATTERED

摘要

The present invention relates to a method for solidifying a surface layer of a soft ground, comprising: a solidifying material storage step of storing a powdery solidified material in a silo; a solidified material loading step of loading the solidified material stored in the silo into a closed solidified fire chamber provided in a solidified material transporter through a transfer pipe; a solidifying material transport step of moving the solidifying material transporter to a position capable of supplying the solidified material to a first mixed position where the modified soil is to be produced on the soft ground; a solidification material supply step of supplying the solidification material from the solidification material carrier to the first mixing position; a raw soil improvement step of mixing the solidified material and the raw soil of the first mixing position on a soft ground by a mixing device to produce improved soil; The modified soil solidification step of curing the modified soil after compacting it with a compaction roller; It not only fundamentally prevents air pollution as the solidifying material in powder form does not flow into the atmosphere during the surface layer solidification process of soft ground, but also lowers the cost of improvement work and increases the work speed, Provided are a surface layer solidification method of a soft ground that can reduce the time and cost of the ground improvement construction, and an apparatus used therefor.
