However, in the related art, when the grouting machine is working, a large amount of gas will be generated during the stirring process
These gases will be trapped in the slurry when the slurry solidifies and reduce the strength of the slurry, resulting in the failure of water plugging

Abstract

The invention discloses a slip casting machine. The slip casting machine comprises a stirring tank, a stirring shaft arranged in the stirring tank, and a plurality of groups of stirring blades which are arranged on the stirring shaft; each group of stirring blades comprises a first stirring blade, and a second stirring blade; each second stirring blade is arranged to be opposite to the corresponding first stirring blade. The slip casting machine is capable of eliminating bubbles in slurries, and increasing the strength after slurry solidification.

Description

technical field [0001] The present application relates to the field of tunnel excavation, in particular to a grouting machine. Background technique [0002] During tunnel construction, fault fracture zones are often encountered. When construction is carried out in the fault fracture zone, water and mud gushes often occur. If not dealt with in time, it will lead to tunnel collapse. In related technologies, the method of grouting and water blocking is generally adopted to prevent water and mud gushing. When grouting, a grouting machine is generally used for grouting. However, in the related art, when the grouting machine is working, a large amount of gas will be generated during the stirring process. These gases will be trapped in the slurry when the slurry is solidified to reduce the strength of the slurry, resulting in the failure of water plugging. Contents of the invention [0003] The main purpose of the present application is to provide a grouting machine, compris...
