Drag reduction system for prefabricated engineering foundation installation and construction method
The invention discloses a drag reduction system for prefabricated engineering foundation installation and a construction method. The drag reduction system comprises a thixotropic slurry system, an Internet of Things system and a drag reduction sleeve. A top annular channel is formed in the top of the wall of the resistance reduction sleeve, an access hole and a thixotropic slurry inlet are formed in the top of the top annular channel, the thixotropic slurry inlet is connected with a thixotropic slurry system, a pressure valve is connected to the thixotropic slurry inlet, and a plurality of slurry channels are connected to the bottom of the top annular channel; the slurry channel is connected with at least one lower annular channel arranged in the circumferential direction of the resistance reducing sleeve, a plurality of slurry outlets communicated with the outer side face of the resistance reducing sleeve are formed in the lower annular channel in the circumferential direction, one-way flow limiting valves are arranged at the slurry outlets, and pressure sensors are arranged at the slurry outlets. The thixotropic slurry system comprises a control valve, and the Internet of Things system is connected with a pressure valve, a pressure sensor and the control valve; the method has the advantages of being convenient to construct, high in construction quality and wide in applicability.
本发明公开一种用于预制类工程基础安装的减阻系统及施工方法，包括触变泥浆系统、物联网系统以及减阻套筒；减阻套筒的筒壁顶部开设有顶部环形通道，顶部环形通道的顶部设置有检修口以及触变泥浆进口，触变泥浆进口与触变泥浆系统连接，所述触变泥浆进口处连接压力阀，所述顶部环形通道的底部连接有若干泥浆通道，所述泥浆通道连接有至少一个沿减阻套筒周向设置的下部环形通道，下部环形通道上沿周向开设有若干与减阻套筒外侧面连通的出浆口，出浆口处均设置单向限流阀，出浆口处设置有压力传感器；触变泥浆系统包括控制阀，所述物联网系统与压力阀、压力传感器、控制阀连接；本发明有着施工方便、施工质量高、适用性广的优点。
