Grouting pump is an important grouting machine in the construction project

Grouting pump is to make a certain material into slurry, with a syringe pump to the pressure to the formation or gap to spread the gel or curing, in order to achieve the purpose of strengthening the formation or seepage plugging. Grouting technology is widely used in high-rise building ash mortar transport reservoirs, hydropower stations, ports, terminals in a variety of pressure grouting, foundation treatment, soft foundation reinforcement grouting, tunnel mine subway construction backfill grouting bolt support. At this stage the main application of the grouting process has compaction grouting, bolt support, curtain grouting, high pressure jet spray.   

In the construction project grouting pump is an important grouting machine, often on the grouting pump good maintenance and maintenance habits, can effectively extend the life of the machine to ensure the normal operation of the equipment in use, reduce the failure rate, improve work efficiency, reduce maintenance costs. Need to regularly maintain the grouting pump, to prevent the main Do not use, the first time to clean the grouting pump pipe to prevent the residual cement slurry solid up, causing clogging, to lubricate the parts of the brush oil to prevent rust, loosening of the screw to tighten. After long-term use, need to change the box of lubricants. Long time not used, to do a good anti-rust, moisture-proof work. Need to carefully maintain the scientific maintenance to improve the life of the injection pump.

Due to the limitation of the grouting process, the reliability of the grouting and adding solid is relatively poor, the reliability of the uniformity and strength guarantee is relatively poor, the quality control and inspection of the construction process are uncertain, and the effect is sometimes less Body reinforcement strength requirements. The effectiveness of the reinforcement construction should be evaluated comprehensively when the grouting reinforcement technology is used in the deep excavation. The depth of grouting reinforcement does not include the grouting reinforcement of the bottom of the wall or the bottom of the pillar in the foundation pit. Grouting machine, grouting pump accessories, high pressure grouting pump, high pressure mud pump, high pressure grouting machine.

Grouting includes separation grouting, buried pipe method, low slump mortar method, columnar bag grouting method. Grouting can improve the bearing capacity of foundation soil and increase the passive earth pressure of the soil inside the wall, but it is not obvious to improve the lateral deformation ability of soil. Generally, the shear strength index and the lateral ratio coefficient of soil are not considered in the calculation. In the foundation pit is shallow or the environment is still good sand or powdery soil can be used within the grouting ground reinforcement treatment.
