The formed side wall of the retaining wall can play a role in guiding the cutter body, so that the multi-surface side-by-side retaining wall is convenient to construct. And the retaining walls can be tightly matched, so that the tightness between the retaining walls is ensured.
Preferably, the front end of the cutter body is provided with a boss; the front end of the boss is provided with a slotted cone; the grouting outlet of the grouting hole is formed in the side wall of the boss. The grouting outlet is prevented from being directly contacted with soil, and the grouting holes can be prevented from being blocked by the soil. And the slotting cone can reduce resistance and facilitate slotting.
Preferably, the boss is located at one side of the blade body, and the grouting outlet faces the inner side of the blade body. The slurry is convenient for filling the strip-shaped groove.
Preferably, the lengths of the slotted cones respectively positioned at the two sides of the front end of the cutter body and the cutter head extending out of the cutter body are equal and are larger than the length of the cutter head extending out of the cutter body in the middle. In the slotting process, the two sides of the front end of the cutter are firstly contacted with the ground, so that positioning is realized, deflection caused by vibration is prevented, and the work is stable.
Preferably, the blade body is detachably connected with the tool bit. Is convenient for the disassembly and replacement of the cutter head.
Preferably, the cutter body is composed of a cutter body head and a cutter body plate, and the cutter head penetrates through a through hole in the cutter body head to be connected with the cutter body plate, so that the cutter body head and the cutter body plate are abutted tightly. The worn grooving cone is convenient to replace.
Preferably, the cutter body is provided with a square pin hole for conveying the square lock pin. The square pin and square pin hole are connected in a firmer way.
The invention has the advantages that the deep and narrow square groove can be excavated, grouting can be completed, and a thin retaining wall can be constructed; tightness among the multi-surface retaining walls can be ensured; the quality of the retaining wall is improved; the disassembly and the replacement of parts are convenient; can prevent blockage; the work is stable.
