Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the exposure of the stratum can easily cause quicksand and quicksand, which will cause the top of the tunnel and the surrounding rock of the side wall to collapse and become unstable. Use the air pipe to blow off the sand scattered in the grouting hole. Insert the grouting pipe into the grouting hole and inject grout into the grouting pipe. When the air pipe blows off the grouting hole, the The blown dust has a great impact on the site environment and operators

Abstract

The invention discloses a tunnel grouting equipment and process, which includes a blowpipe, one end of the blowpipe is connected with a compressor, the blowpipe is provided with a dust suppression mechanism, and the dust suppression mechanism includes a buckle cover fixed on the blowpipe. The opening of the buckle cover faces the direction of the air outlet of the blowpipe, and a spray mechanism is arranged on the buckle cover, and the spray mechanism sprays water mist to the inner cavity of the buckle cover; a fixed filter screen is fixed on the buckle cover, and the fixed filter The net is arranged obliquely, and a relief hole is opened on the buckle cover, a baffle plate that covers the relief hole is hinged on the buckle cover, a pressing mechanism is arranged on the baffle plate, and an overflow hole is opened on the buckle cover. Orifice. The invention has the effect of reducing dust when the grouting hole is cleaned.

Description

technical field [0001] The invention relates to the technical field of tunnel construction reinforcement, in particular to a tunnel grouting equipment and process. Background technique [0002] With the continuous development of my country's national economic construction, engineering projects are becoming more and more complex, and various unfavorable engineering geological conditions have brought many difficult problems to the normal construction and operation of underground engineering. , Contingency problems are quite common and harmful. The treatment of such geological disasters usually adopts the grouting method. First, the area near the construction is reinforced by grouting, and then the construction is carried out to ensure the safe and efficient development of the project. [0003] The Chinese invention patent with the authorized notification number CN103993607B discloses a steel flower tube controlled grouting anti-slip composite structure and its rapid constructi...
