Foundation pit waterproof curtain reinforcement method
The invention relates to sealing-up of foundation pits, and provides a foundation pit waterproof curtain reinforcement method. During construction of the foundation pit, a high pressure jet grouting pile is punched between every two adjacent drilling piles in a sleeved mode. When cement is not solidified, a grouting pipe is inserted into each high pressure jet grouting pile. Whether the foundation pit leaks is detected, if yes, grout is injected into the corresponding grouting pipe, and the grout reinforces the leaking position from a grouting hole. According to the foundation pit waterproof curtain reinforcement method, during construction of the foundation pit, the grouting pipes are buried into the high pressure jet grouting piles in advance, when it is detected that the foundation pit does not leak, the grouting pipes can serve as inclined lateral pipes, the deep layer horizontal displacement of a foundation pit supporting structure can be monitored, and the monitoring expenses are reduced. If the foundation pit leaks, grout reinforcement is carried out to the leaking position through the grouting pipes, the operation is convenient and easy to implement, and the reinforcement cost is quite low. As grout reinforcement is carried out from the inside of the high pressure jet grouting piles, the leakage problem of the foundation pit can be solved fundamentally, and the reinforcement effect is remarkable.
