Grouting mortar pump works
Grouting mortar pump works diversification. Grouting slurry material is divided into: cement grouting, cement grouting, clay grouting, cement clay grouting, silicate, grouting sodium or polymer solution chemical grouting. Grouting mortar pump works: 1, the slurry pressure to the cracks in the foundation of the building, the fault fracture zone or the building itself seams, cracks in the project. 2, through the grouting can improve the infiltration of stratum or building impermeability and integrity, improve foundation conditions, to ensure the safe operation of hydraulic structures. According to the composition of the irrigated stratum, it is divided into rock grouting, karst grouting, gravel layer grouting and silty sand layer grouting. 4, grouting pressure is divided into: less than 40 × 105Pa conventional pressure grouting, greater than 40 × 105Pa high-pressure grouting. 5, according to grouting mechanism is divided into: the general pressure of the pressure grouting, the use of higher pressure in the rock in the original fracture to support or form a new fracture splitting grouting.
