SOIL-CEMENT WALL CONSTRUCTION METHOD AND EXCAVATOR

摘要

<P>PROBLEM TO BE SOLVED: To provide a soil-cement wall construction method and an excavator for use in the soil-cement wall construction method reducing water consumption while securing the fluidity of a mixture of excavated sediment and slurry injected into the ground in constructing a soil-cement wall. Ž<P>SOLUTION: This soil-cement wall construction method using a hydrofraise excavator 10 comprises an excavation process S10 for excavating the ground downward by the excavator 10 and injecting excavation slurry and air bubbles into the periphery of an excavated part; a construction process S20 for injecting construction slurry into the periphery of the excavator 10 after the excavation process and pulling up the excavator 10 while rotating a rotary cutter 14 to stir and mix the excavation or construction slurry and the excavated sediment produced in excavating the ground in the excavation step S10; and a curing process S30 hardening the mixture of the excavated sediment and stable slurry stirred and mixed in the construction process S20.
