They are suitable for the supporting structure of foundation pit support projects. PC method piles are adaptable to a wide range of strata, have significant water-stopping effects, high wall quality, high adjustability of profile spacing and insertion depth, save engineering workload, and have no mud pollution. They are being used more and more widely in foundation pit retaining in various complex environments.

[0003] During the foundation pit construction process, after the foundation pit is excavated, the slope range on both sides of the excavated ramp becomes larger and larger, and the PC method piles at the ramp excavation port will be stabilized using a reinforcement device. However, the existing PC method pile reinforcement device has a complex structure and is very cumbersome to install and disassemble, which wastes the time of construction workers and reduces the overall construction efficiency. Therefore, in response to the above problems, we propose a PC method pile reinforcement device for the ramp excavation port. Utility Model Content
