Laboratory multi-slurry high-pressure grouting device and grouting method

Abstract

The invention provides a laboratory multi-slurry high-pressure grouting device and a grouting method. The laboratory multi-slurry high-pressure grouting device comprises a gas supply system, a slurrying system, a mould injecting system and a plurality of pipelines; the gas supply system comprises a plurality of gas pumps and a plurality of pressure stabilizing tanks, outlets of the gas pumps are connected with inlets of the pressure stabilizing tanks, and the gas pumps deliver and store generated gas into the pressure stabilizing tanks; the slurrying system comprises a plurality of slurrying units, and each slurrying unit comprises two high-pressure tanks, wherein grouting holes and gas feeding holes are formed in the upper parts of tank bodies of the two high-pressure tanks correspondingly, an outlet of each pressure stabilizing tank is connected with the gas feeding holes of the two corresponding high-pressure tanks to provide high-pressure gas for the high-pressure tanks, and the high-pressure tanks are used for storing slurry and maintaining slurry fluidity; and the mould injecting system comprises a grouting mould. According to the laboratory multi-slurry high-pressure grouting device, multi-slurry continuous high-pressure grouting can be achieved, double-slurry or multi-slurry accurate mixing of various proportions can be achieved, operation is convenient and quick, the pressure bearing capacity is high, the pressure is stable, and the grouting effect is good.

Description

technical field [0001] The invention belongs to the technical field of grouting, and in particular relates to a multi-slurry high-pressure grouting device and a grouting method for a laboratory. Background technique [0002] In the field of geotechnical engineering, grouting reinforcement is an effective way to solve many complex problems, but due to the complexity of the project, many grouting reinforcement works cannot be tested on the construction site, but many basic research work needs to be carried out in the laboratory . Therefore, laboratory grouting tests are widely used. At present, in order to complete the laboratory grouting test work, many scholars have developed and assembled a variety of laboratory grouting test devices, but there are many problems in these laboratory grouting test devices. For example, many grouting tests are done with manual grouting pumps, the pump pressure is unstable, and test data under continuous and stable pressure cannot be obtained...
