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 transport step of filling the solidified material stored in the silo into the closed solidified fire chamber without leakage of the solidified material through a transfer pipe, and moving the solidified material transporter for transporting the solidified fire chamber to the modified soil supply; a solidifying material supplying step of supplying the solidified material from the solidified material chamber to the sealed accommodation chamber provided in the modified soil supply unit through a supply pipe; an improved soil generating step of generating, in the modified soil feeder, the modified soil mixed with the soil of the soft ground and the solidified material; an improved soil supply step of supplying the modified soil while the modified soil supply unit moves the soft ground; an improved soil dispersing step of more widely dispersing the modified soil supplied from the modified soil feeder by a dozer; an improved soil compaction step of compacting the modified soil dispersed by the doser with a compaction roller; A curing step of curing the modified soil; 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 ground improvement construction, and an apparatus used therefor.
