Description

Grouting material conveying device

Technical Field

The utility model relates to the field of slurry conveying, in particular to a conveying device for grouting materials.

Background

The grouting material is a general term for engineering materials which are selected for achieving a determined engineering purpose, can exist in a liquid state, can be conveniently injected into internal spaces such as cracks, fissures and pores of a corresponding medium by utilizing a hydraulic pressure, air pressure or electrochemical principle, and has cementing and curing capabilities, so that a leakage channel of the medium is blocked, and physical properties and mechanical properties are improved. The slurry material is a fluid material which is injected into gaps and holes of a stratum, rock or a structure under the action of pressure to achieve the effects of increasing the bearing capacity, preventing leakage, improving the overall performance of the structure and the like, and is formed by mixing a main agent, a solvent (water or other solvents) and an additive (a curing agent, a stabilizing agent and the like). The grouting material is generally referred to as a main agent in the grout. The grouting material must be a material that can be cured.

When grouting in a common stratum, in order to obtain a good grouting effect, the grout is required to have two characteristics at the same time: firstly, the slurry is required to keep good fluidity in a pumpable period, and the viscosity is not greatly increased; secondly, the viscosity of the slurry is required to be rapidly increased after the pumpability, and the time interval from the pumpability to initial and final setting is required to be short. The first feature is beneficial to fully injecting the slurry into the pores and cracks of the stratum, and the second feature is beneficial to bonding the slurry with rock-soil mass and preventing the slurry from being washed by underground water before solidification.

However, these two characteristics are contradictory, and a general slurry often has only one of the characteristics, but cannot simultaneously have the other characteristic, so that the two characteristics cannot be perfected. In some cases, in order to rapidly plug and fill the rock-soil body, quick setting slurry is adopted. When the existing quick-setting slurry is conveyed through a pipeline, the slurry is easily coagulated into blocks in the pipeline due to long-time transportation, the pipeline is blocked, and difficulty is caused to transportation, so that the circulation of the pipeline is reduced.
