[0003] In a soil cement column wall, a wall made of soil cement between a plurality of H-shaped steels to be built therein plays a role of a sheet pile, and when excavating the ground for constructing a structure, By removing a part of the wall on the side of the excavation space, the surface of the H-shaped steel flange is usually exposed. Conventionally, in removing the wall portion, when the soil cement has a low strength, a method of scraping the soil cement with a bucket of an excavator and forming the surface using a pick or the like has been adopted. Further, in the case of a sand layer, a gravel ground, etc., the soil cement strength is increased, and a picking operation is required for a wall portion, and a lot of time and labor are required for the removing operation.
