影響を与えない）[Scope of Claims] Cut-and-cut propulsion in which slide panels B made of flat plates face each other and are supported between the slide panels B by a rigid support frame A having a front fixed A-1 and a rear cantilever A-2. The front of the machine is excavated and the buckets of the excavator are used to alternately pull out the slide panels B, which are under the pressure of the earth. Next, slide panel B
The propulsion machine moves forward by pulling out the support frame A that is stuck in between. It is possible to excavate and construct a propulsion retaining wall using only the excavating force (traction force) of an excavator without using expensive or complicated hydraulic equipment, etc., but the rear overhang of slide panel B When installing the earth retaining material C-1 inside B-2, if the slide panel extension part B-2 is thick, a gap will be created between the earth retaining material C-1 and the ground, which will cause the ground to loosen. There is a possibility that this may occur. Rear overhang part B- of slide panel B
It is necessary to make the thickness of 2 as thin as possible. As a countermeasure for this, as shown in Figure 3, the outside of the slide panel overhang B-2 (the surface on which earth pressure is applied) is reinforced with reinforcing material E (channel, H-shaped steel, etc.) to strengthen the soil of the slide panel overhang B-2. A device that prevents bending due to pressure, minimizes the gap between the earth retaining material C-1 and the ground, and prevents the ground from loosening. (Note that the loosening of the ground due to the reinforcing material E of the slide panel overhang B-2 has almost no effect on the ground because the cross-sectional area of the reinforcing material E is small.)
