Tunnel pipe shed grouting machine with bubble triturating function

Abstract

The invention provides a tunnel pipe shed grouting machine with a bubble triturating function, relates to the field of shallow-buried underground excavation tunnel construction equipment, and solves the problem that the construction quality is not high due to the fact that an existing tunnel pipe shed grouting machine cannot eliminate bubbles in grouting slurry. The tunnel pipe shed grouting machine with the bubble triturating function comprises a machine body, a slurry through pipe, a grouting opening, a bearing support, a driving motor, a front rolling wheel, a heat dissipation window and arear rolling wheel. After improvement, a first triturator and a second triturator are driven to rotate through a transmission triturating mechanism, then grouting slurry is hammered, and thus the elimination of air bubbles in the grouting slurry is realized; an air suction and exhaust mechanism can suck and exhaust air in the triturated air bubbles, the air bubbles are prevented from being formedagain, the situation that a pipe shed is not firm in reinforcement due to the fact that the air bubbles are honeycomb after the grouting slurry is solidified can be prevented through overall matching,the construction quality can be improved, potential safety hazards are reduced, and follow-up construction operation is facilitated.

Description

technical field [0001] The invention relates to the field of construction equipment for shallow buried tunnels, in particular to a tunnel pipe shed grouting machine with the function of crushing air bubbles. Background technique [0002] Nowadays, the shallow burial and underground excavation method is widely used in tunnel construction. It has several procedures, among which there is an indispensable procedure, that is, pre-support and pre-reinforcement treatment. Pre-support and pre-reinforcement treatment requires grouting reinforcement, which requires a grouting machine. Although the existing technology of tunnel pipe roof grouting machines is becoming more and more perfect, there are still the following deficiencies to be solved: [0003] The grouting slurry often contains a large number of air bubbles, and the existence of air bubbles will make the pipe shed insufficient reinforcement, resulting in water leakage and settlement problems in the tunnel, which not only aff...
