Wind-guiding chemical grouting device and grouting method of the same

Abstract

The invention relates to a wind-guiding chemical grouting device, and further relates to a method for grouting through the wind-guiding chemical grouting device. The wind-guiding chemical grouting device comprises a grouting pump, an air compressor, a wind-thick liquid mixer and a corresponding pipeline, wherein the wind-thick liquid mixer is arranged in the middle of the pipeline and is provided with a wind inlet pipe, a thick-liquid inlet pipe and a thick-liquid outlet, the wind inlet pipe is connected with a first wind outlet pipe of the air compressor, the thick-liquid inlet pipe is connected with a thick-liquid outlet pipe of the grouting pump, the thick-liquid outlet is connected with a grouting buried pipe, a second wind outlet pipe led out from the air compressor is connected with a wind inlet buried pipe, and the front end of the wind inlet pipe, the front end of the thick-liquid inlet pipe and the wind inlet buried pipe are respectively connected with a valve. The wind-guarding chemical grouting device and the grouting method of the wind-guiding chemical grouting device achieve continuous processing of wind compressing, wind-thick-liquid mixing and pure-thick-liquid compressing processes, water is driven by wind, and therefore thick liquid is prevented from reacting with the water in the grouting process and congestion is avoided.

Description

technical field [0001] The invention relates to an air-induced chemical grouting device and a grouting method, in particular to a grouting device and a grouting method that can address water leakage situations with high water pressure and large flow. Background technique [0002] Water leakage is one of the common diseases in projects under construction or in existing projects such as reservoir dams and underground structures. It mainly manifests in various types of water leakage such as structural joints, deformation joints, cracks, and fissures. In severe cases, it will directly affect the construction or construction of the project. Operation and use of buildings. At present, for the above-mentioned water leakage treatment methods, the construction method of chemical grouting is mainly used in engineering. Most of the grouting materials used are water-soluble or oil-soluble polymer elastic materials, which will immediately react and expand when exposed to water. , can ad...

Problems solved by technology

However, the existing chemical grouting methods use electric pumps, hand pumps, etc., which rely solely on pressure to push, and only have a single function of air pressure or grouting. In the presence of pressurized water, it is easy to cause the grout to go up the water. Neutralization reacts with water, causing congestion due to the increase of its own viscosity and the increase of pressure loss along the way. The final result is that the grout diffusion range is limited and the expected grouting effect cannot be achieved.
