Problems solved by technology

Fully manual grouting in the grouting mold is used to obtain the grouting body directly after maintenance and processing, and the required experimental data can be obtained simply and quickly, while there is no grouting experimental device for the laboratory in the prior art
Due to the limitations of actual engineering, it is relatively difficult to study the grouting diffusion radius in pressure grouting

Abstract

The invention provides a pressure grouting experiment device comprising a slurry supplying device, wherein the slurry supplying device is communicated with a slurry hole of an experiment mould; a lower slurry hole of the experiment mould is communicated with a slurry recycling barrel; a plurality of pipelines are arranged on the outer wall of the experiment mould from top to bottom; each pipeline is provided with a pressure gage; and throttling valves are arranged between the slurry supplying device and the experiment mould and also between the experiment mould and the slurry recycling barrel. According to the pressure grouting experiment device disclosed by the invention, grouting stone bodies with the regular shape can be easily and conveniently obtained through using different moulds, and slurry dispersion radiuses under the different conditions can be obtained. In the testing process, pressure P provided by matching the pressure gages and a flow meter with a jack can relatively and effectively analyze influences of a testing parameter to each physical mechanical property of the stone bodies and the slurry dispersion radiuses. According to the pressure grouting experiment device disclosed by the invention, the grouting amount can be quantized, so that components of the stone bodies are also quantized. The pressure grouting experiment device is small and exquisite, convenient and easy to use, and is particularly suitable for being used in a laboratory.

Description

Technical field [0001] The invention involves the field of experimental device, especially a multi -functional experimental device suitable for laboratory pressure grouting. Background technique [0002] At present, geological disasters are frequent. Swinging can reinforce the soft strata in situ and can change its inherent physical mechanical properties, so it is widely used in civil engineering engineering.Due to complex strata conditions and the concealment of grouting construction effects, the research of grouting theory lags behind engineering practice.The existing grouting systems are mostly targeted at actual grouting operations, and there are certain restrictions on laboratory grouting and better interior experimental research. [0003] The laboratory grouting the physical mechanical characteristics of stone body is obtained, and it is mostly tested after cutting it.Perform full artificially grouting in the grouting mold to obtain the direct maintenance and processing of ...
