HIGH-EFFICIENCY NORMAL-PRESSURE TOOL REPLACEMENT CONSTRUCTION METHOD FOR WATER-RICH SANDY COBBLE STRATUM

摘要

A high-efficiency normal-pressure tool replacement construction method for a water-rich sandy cobble stratum. According to the construction method, any two adjacent plain piles (10) are meshed together, such that the reinforcing integrity effect is better. The construction method shows high stratum reinforcing speed and high safety in tool replacement operation, and can shorten the construction period and save on costs. The construction method can reduce noise and vibration, has a low impact on stratum and the surrounding environment, and does not require any slurry operation, thereby making a construction site clean, reducing ground pollution, saving on energy, and meeting green construction standards and requirements.
