Problems solved by technology

Traditional foundation excavation generally adopts mechanical slotting or mud circulation and slag discharge. During excavation, corresponding support structures must be set up according to the excavation situation. The excavation slot width is required to be wide, and the excavation process is cumbersome.
When the soil (dam) needs local repair, water stop or reinforcement, it is necessary to build a retaining wall with a thickness of less than 50mm. Traditional foundation excavation equipment cannot directly excavate a long strip-shaped deep groove with a narrow width, and build a thin retaining wall. wall

Embodiment Construction

[0020] Such as Figure 1 to Figure 2 As shown, a strip-shaped deep groove foundation excavation and grouting cutter includes a strip-shaped blade body 1 and several cutter heads 2; the cutter heads 2 are arranged on the strip surface at the front end of the blade body; The slag discharge hole 3 for discharging waste slag and the grouting hole 4 for injecting retaining wall grout. Both sides of the blade body 1 are protrusions 5 and grooves 6 which can cooperate with each other respectively. The cross-section of the protrusion 5 can be triangular, rectangular or arc-shaped.

[0021] In order to connect with external equipment, the slag discharge outlet 3.2 of the slag discharge hole 3 and the grouting inlet 4.1 of the grouting hole 4 are all arranged at the rear end of the knife body 1; Head 2 sides. The front end of the knife body 1 is provided with a boss 8; the front end of the boss 8 is provided with a slotted cone 7;

[0022] The boss 8 is located on one side of the bl...

Abstract

The invention discloses a tool for bar-shaped deep groove foundation excavation and grouting. The tool comprises a bar-shaped plate tool body and a plurality of tool bits. The tool bits are arranged on the bar-shaped face of the front end of the tool body. The tool body is provided with a residue discharge hole for discharging waste residues, and a grouting hole for pouring in parapet paste. The technical scheme is adopted, a bar-shaped groove is directly dug by arranging the bar-shaped plate tool body and the tool bits at the front end of the tool body, the waste residues are discharged through the residue discharge hole, paste is poured in through the grouting hole, and a thin parapet is built.

Description

technical field [0001] The invention relates to the field of strip-shaped deep and narrow foundations, in particular to a cutter for excavating and grouting strip-shaped deep groove foundations. Background technique [0002] Strip deep and narrow foundations are mainly used to construct underground diaphragm walls, waterproof and drainage facilities, etc. Traditional foundation excavation generally adopts mechanical slotting or mud circulation slag discharge. During excavation, corresponding support structures must be set up according to the excavation situation, which requires a wide excavation slot width and the excavation process is cumbersome. When the soil (dam) needs local repair, water stop or reinforcement, it is necessary to build a retaining wall with a thickness of less than 50mm. Traditional foundation excavation equipment cannot directly excavate a long strip-shaped deep groove with a narrow width, and build a thin retaining wall. wall. Contents of the invent...
