Abstract

The invention belongs to the technical field of engineering construction and specifically discloses a grouting pipe bit for road construction. The grouting pipe bit comprises a drill bit main body, wherein a first chamber is formed in the drill bit main body; a high-pressure runner which is connected with the first chamber is formed on the drill bit main body; a high-pressure nozzle is arranged inthe high-pressure runner; a drill tip is arranged on the lower part of the drill bit main body; a second chamber is formed in the drill bit; the first chamber is connected with the second chamber; anauxiliary grouting hole which is connected with the second chamber is formed on the drill tip; a hydraulic control cut-off unit and a grout backflow unit are arranged in the second chamber. The grouting pipe bit with such a structure is capable of solving the problem of pipeline blocking caused by the stagnation and solidification of residual grout in the channel during high/low pressure conversion process.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, in particular to a grouting pipe drill bit for road construction. Background technique [0002] In the process of road construction, road drilling and road grouting are important links in the process of road construction and maintenance. In the construction process, some use drilling equipment and rotary spraying equipment to implement drilling and high-pressure jet grouting processes respectively. Although this method has a good construction effect, the construction equipment used is correct, the construction period is long, and the cost is high. [0003] The Chinese patent with the publication number CN101250983B discloses a single-pipe omni-directional drilling injection grouting drill bit which can be hydraulically controlled to open and close the auxiliary grouting hole. Low-pressure clean water or slurry can lubricate and cool the drill bit, help the drill bit to discharge...
