Grouting sealing hole stop grout visual experimental device and experimental method thereof

Abstract

The utility model provides a grouting sealing hole stop grout visual experimental device which comprises a pressure supply system, a grout supply system and a sealing hole stop grout visual system which are mutually connected. The pressure provided by the pressure supply system allows the grout in the grout supply system to be injected into the transparent sealing hole stop grout visual system. The device also comprises a pair of monitoring systems which carry out whole-process monitoring on the grout injection process. An experimental method comprises the steps of debugging and starting the monitoring system to carry out recording, closing the pressure adjusting value of the pressure supply system and pressing air into the system, starting the grout supply system such that the grout enters into the sealing hole stop grout visual system under the effect of high pressure air under a set start and stop time alternative change parameter and pulsing grouting is effectively simulated, and collecting and processing various parameters in a grouting experimental process through a monitoring system and analyzing the parameters to complete the experiment. The experimental device has the advantage of simple structure, convenient assembly and low cost, and the pressure change and sealing hole stop grout parameters can be effectively simulated.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering foundation treatment grouting, and in particular relates to a grouting experimental device and method for sealing holes and stopping grouting. Background technique [0002] The hole sealing process is widely used in water conservancy, mining, roadbed and landfill projects. The existing grouting and sealing technology can be roughly divided into three categories: grout stopper method, orifice sealing method and slurry sealing method. The parameters of grouting and sealing holes in engineering are mainly determined based on experience. Slurry, tubes, etc. [0003] In view of the above problems, it is urgent to obtain effective grout sealing process parameters. At present, the research on sealing process parameters is mainly concentrated in mining engineering, mostly based on mechanical models and field tests. For example: Ge Haolong of Chongqing University and others proposed "Mechanical M...
