According to the technical scheme, the variable-frequency vibrating pile hammer transmits exciting force to the cutter through the extension rod, soil mass is cut (liquefied), when larger stone blocks are encountered, the frequency or the power can be increased to crush the stone blocks, the cutter is sunk, and a strip-shaped groove is formed by excavation. The negative pressure slag pumping system cleans waste slag generated in the slotting process through slag pumping holes. In the process of pulling out the cutter, the grouting system injects slurry into the strip-shaped groove through the grouting holes to form a retaining wall, so that the aims of repairing, water stopping or reinforcing are fulfilled. And through lengthening extension bar, can realize the fluting of different degree of depth, its application scope is wide.
Preferably, two ends of the extension bar are respectively provided with mortise and tenon-shaped structures which can be matched with each other; the two extension bars and the cutter are matched through the mortise-tenon structure, and are locked through the square pin. The cutter is accurately installed, firm connection between connected parts can be guaranteed, and dislocation does not occur when the cutter is dug down.
Preferably, the two sides of the cutter are respectively provided with a protrusion and a groove which can be matched with each other. The formed side wall of the retaining wall can play a role in guiding the cutter, so that the multi-surface retaining wall is convenient to construct. And the multi-surface retaining walls can be tightly matched, so that the tightness between the retaining walls is ensured.
Preferably, a side wall of the front part of the cutter is provided with an inclined plane. When the retaining wall is excavated, the cutter can automatically bear a lateral force to enable the cutter to be clung to the retaining wall adjacent to the cutter, so that the retaining walls can be tightly connected.
Preferably, the cutter comprises a cutter body and a plurality of cutter heads; the tool bit is detachably connected with the tool body. Is convenient for the disassembly and replacement of the cutter head.
Preferably, the slag extraction guide hole is provided with channels positioned at two sides of the tool bit. Can effectively remove waste residues, reduce the content of waste residues in the deep groove, reduce impurities in slurry, and contribute to improving the quality of the retaining wall.
Preferably, the lengths of the cutter heads at the two sides of the front end of the cutter extend out of the cutter body are larger than those of the cutter heads at the middle part of the cutter body. In the slotting process, the cutter heads at two sides firstly contact the ground to realize positioning, so that deflection caused by vibration is prevented, and the work is stable.
Preferably, the front end of the cutter body is provided with a boss; and an outlet of the grouting guide hole is formed on the side wall of the boss. Can prevent mud from blocking grouting guide holes.
The invention has the beneficial effects that the narrow strip-shaped deep groove foundation excavation and 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.
