HIGH PRESSURE GROUTING METHOD
The high-pressure filling and leakage-free leakage engineering method is the most common leakage-prevention technology for repairing the leakage of current repairs. The high-pressure injection and leakage-prevention engineering methods used in buildings, tunnels and even basement and MRT stop-leakage engineering methods are numerous. In the widely used, there are still many defects, such as: lack of perfusion pressure, needle misplacement, etc., in order to improve the effectiveness of leak-proof, to ensure construction quality, the following description will be high-pressure injection stop leakage method.
