Grinding device for tunnel construction based on renewable resources

Abstract

The invention discloses a grinding device for tunnel construction based on renewable resources. The grinding device comprises a grinding device body and is characterized in that the grinding device body comprises a grinding shell, wherein the grinding shell is connected with the outside in a constant torque mode; grinding teeth are arranged on the grinding shell; a bottom plate is connected to the interior of the grinding shell; inertia balls are connected to the two ends of the bottom plate; a pressing and clamping device is connected to the outside of the grinding shell; the outer wall of the grinding shell is of an arch-shaped flexible structure; a triangular sleeve is rotationally installed in the middle of the grinding shell; a plurality of through holes are formed in the bottom of the triangular sleeve; clamping blocks are installed in the through holes in a sliding mode; the pressing and clamping device comprises a space shell; a partition plate is installed in the middle of the space shell in a sliding mode; air bags are correspondingly arranged on the two sides of the partition plate; the earth is arranged on one sides of the air bags; the two earth are connected in a communicating mode; and a control rod is connected to one sides of the earth. The grinding device has the characteristic of being convenient to insert.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a grinding device for tunnel construction based on renewable resources. Background technique [0002] During tunnel construction, it is usually necessary to grind the inner wall to make it smooth, and at the same time prevent stones from falling and hurting people. However, the existing tunnel grinding work usually has a uniform specification for its inner diameter, and the degree of compaction of the soil varies greatly. Sometimes it will lead to the implementation of subsequent work such as inserting nails to become very unsafe, and parameters such as the depth and strength of inserting ribs need to be adjusted frequently. Therefore, it is necessary to design a grinding device for tunnel construction based on renewable resources that is convenient for inserting ribs. Contents of the invention [0003] The purpose of the present invention is to provide a grinding ...
