Grouting device for metro tunnel disease detection

Abstract

The invention discloses a grouting device for metro tunnel disease detection. The grouting device comprises a sleeve, a deflector rod, a measuring scale, a rubber gun head, an illuminating lamp, a supporting rod, an outer gun pipe, a trigger, a gun stock, a push block, a push rod, a bracket, a spring, a limiting plate, a baffle, an inner roller, a motor, a gear, slide grooves and a piston. The depth and size of a notch in a tunnel are measured through the measuring scale; the recovery purpose is achieved by deflecting the measuring scale through the deflector rod, and the measuring scale is protected through the sleeve; the purpose of facilitating observation and detection under dark situation is achieved through the illuminating lamp; the gear is driven to rotate through the motor, the gear is engaged with a sawtooth opening at one end of the inner roller, and the purpose that the inner roller rotates in the outer gun pipe is achieved; and the purpose of pushing the piston to move isachieved by connecting the tripper with the push block, and the grouting purpose is achieved.

Description

technical field [0001] The invention relates to a grouting device, in particular to a grouting device for detecting defects in subway tunnels. Background technique [0002] Grouting is divided into ceramic craft grouting and construction engineering grouting. Ceramic technology grouting is a process of injecting prepared mud into ceramic production. Construction engineering is a method of injecting some curable grout into cracks or pores in rock and soil foundations by appropriate methods, and improving its physical and mechanical properties by means of replacement, filling, extrusion, etc. From the perspective of existing technologies, grouting The device is not easy to carry, and other detection devices need to be carried at the same time, and the slurry is easy to solidify in the device to cause harm to the device, and the practical cycle is short. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the purpose of the pr...
