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 technology. The tunnel grouting equipment comprises a blowing pipe, wherein one end of the blowing pipe communicates with a gas compressor; theblowing pipe is provided with a dust falling mechanism, wherein the dust falling mechanism comprises a buckle cover fixedly arranged on the blowing pipe, and the opening of the buckle cover faces theair outlet direction of the blowing pipe; a spraying mechanism is arranged on the buckle cover, wherein the spraying mechanism sprays water mist towards an inner cavity of the buckle cover; a fixing filter screen is fixedly arranged on the buckle cover, wherein the fixing filter screen is obliquely arranged; and a receding hole is formed in the buckle cover, a baffle covering the receding hole ishinged to the buckle cover, a pressing mechanism is arranged on the baffle, and an overflow hole is formed in the buckle cover. According to the tunnel grouting equipment and technology, effects of reducing flying dust when a grouting hole is cleaned can be achieved.

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...
