Grouting machine for tunnel construction

Abstract

The invention discloses a grouting machine for tunnel construction. The grouting machine comprises a case, a pipeline collecting shell, an automatic pipe coiling device, a stirring cylinder and a power cavity. The power cavity is formed inside the case, and a peristaltic pump is arranged on one side of the interior of the power cavity; the stirring cylinder is arranged on one side of the top end of the case, and a stirring paddle is arranged at the bottom end inside the stirring cylinder; a control panel is fixed to one side of the surface of the stirring cylinder, a grouting cylinder is arranged on one side of the position, on one side of the stirring cylinder, of the top end of the case, and the pipeline collecting shell is arranged on one side of the outer wall of the grouting cylinder;and the automatic pipe coiling device is fixed inside the pipeline collecting shell, and a grout conveying pipeline is wound around the surface of the automatic pipe coiling device. According to thegrouting machine for tunnel construction, the grout quality is improved, the working efficiency of the grouting machine is improved, the service life of the grout conveying pipeline is prolonged, theworkload of people is reduced, and the equipment using cost is reduced.

Description

Technical field [0001] The present invention relates to the technical field of grouting machines, in particular to a grouting machine for tunnel construction. Background technique [0002] Grouting is one of the important processes in the construction of construction projects. It is to inject certain solidified grout into the cracks or pores of the rock and soil foundation by appropriate methods, and to improve the rock and soil foundation by means of replacement, filling, and extrusion. In tunnel construction, grouting has the functions of preventing seepage, blocking water, consolidating, preventing tunnel collapse, and improving the bearing capacity of the tunnel. At present, the grout in the grouting machine cannot maintain its uniformity, resulting in quality It’s not enough, and many grouting machine installations have cumbersome slurry pipelines, which leads to messy and easy damage to the slurry pipeline. Some grouting machines and mixers generally exist independently, an...

Problems solved by technology

[0002] Grouting is one of the important procedures in the construction of construction projects. It is to inject some curable grout into the cracks or pores of the rock and soil foundation with an appropriate method, and improve the rock and soil foundation by means of replacement, filling, extrusion, etc. In tunnel construction, grouting has the functions of anti-seepage, water blocking, consolidation, preventing tunnel collapse, and improving tunnel bearing capacity. At present, the grout in the grouting machine cannot maintain its uniformity, which leads to quality problems. It is not as good as it is, and many grouting machine devices have cumbersome grouting pipelines, which lead to messy and easily damaged grouting pipelines. Some grouting machines and mixers generally exist independently, and the staff will mix them well. The concrete is transferred to the grouting machine through the transportation equipment. During the transfer process, the moisture in the concrete will decrease to a certain extent, thereby reducing the quality of the concrete, and the effect of concrete transfer increases people's workload, and also increases equipment cost
