[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] single-tube high-pressure grouting Piles is the use of drilling rigs and other equipment, the special nozzle mounted on the bottom side of the grouting tube into the soil after a predetermined depth, a high-pressure mud pump generator to a pressure of about 20Mpa ejected from the nozzle in the slurry out of the direct impact of the destruction of soil, but by the rotation of the grouting pipe and promotion campaign to avalanche down from the soil of soil changes, part with a slurry of fine particles out of the ground, the rest of the soil particles in the role of impact force jet, centrifugal force and gravity force, and slurry mixing, according to a certain proportion of the slurry and soil quality size, hydraulic anchor rig, regularly re arrangement, the most advanced anchor rig, after a certain time solidified, it forms a cylindrical body consolidation in the soil. Construction of water conservancy project process, Chengdu anchor rig, especially earth dam construction process, Hegang anchor rig, in order to make the ground water permeability, seepage stability, strength, carrying capacity, for compression deformation capacity to meet the requirements, it is necessary to Foundation for processing. When dealing with gravel foundation, it will be used in the following ways: 1, clayey cut sink, 2, concrete impervious wall, 3, grout curtain, 4, impervious blanket, 5 drainage decompression measures. When the permeable layer deep gravel foundation, seepage measures to implement the first two difficulties, it can use curtain grouting method. In simple terms, is the use of high-speed jet cutting soil mixed with stirring, to change the structure and composition of the original soil, and water poured into the mud or slurry form coagulated composite body, in order to achieve the purpose of strengthening the foundation and seepage. GZB-40C-pressure injection pump high-pressure jet grouting equipment, high pressure jet grouting to provide high-pressure water is mainly mud. For the new building, highway, railway, underground railways and other soft ground reinforcement, anti-seepage treatment for around foundation, cofferdam and hydropower dams.
