Abstract

The invention relates to the technical field of shield tunneling machines, and discloses a grouting system of a shield tunneling machine for tunnel construction. The grouting system comprises a base;a shield tunneling machine main body is fixedly mounted on the left side of the top of the base; a bottom plate located on the right side of the shield tunneling machine main body is fixedly mounted at the top of the base; and baffles are fixedly mounted on the left and right sides of the top of the bottom plate. According to the grouting system of the shield tunneling machine for tunnel construction, a second material box, a first material box and a rectangular box are arranged, an accelerating agent and mud are stored in the second material box and the first material box respectively and aremixed in the rectangular box finally, according to the meshing relation of bevel gears, when a micro motor is started, the rotation directions of two rotating shafts are opposite, then the rotation directions of two stirring blades are opposite, the accelerating agent and the mud which are mixed in the rectangular box are stirred by the stirring blades, the accelerating agent and the mud can be stirred evenly, and the subsequent operation efficiency of the shield tunneling machine can be improved.

Description

technical field

[0001] The invention relates to the technical field of shield machines, in particular to a grouting system of a shield machine for tunnel construction. Background technique

[0002] Shield machine is the abbreviation of shield tunnel boring machine. It is a kind of equipment used to excavate tunnels. It is generally divided into several types such as manual shield, extrusion shield and semi-mechanical shield.

[0003] The shield machine needs to inject mud into the shield machine when excavating the tunnel. The existing shield machines generally use single-pipe grouting and double-pipe grouting. The single-pipe grouting needs to ensure that the injected mud can enter the shield machine. It condenses quickly, so the length of the pipeline needs to be long enough. If the length of the pipeline is too long, a large amount of mud will remain in the pipeline at the end, so the double-pipe grouting method is often used, but the quick-setting agent and the mud insid...
