Stirring pile underground pressure control system and piling construction method thereof
The invention provides a mixing pile in-ground pressure control system and a piling construction method.The control system comprises a control device, a drill rod and a drill bit, a slurry channel, a signal channel and a gas channel are arranged in the drill rod, and a slurry spraying opening, a gas spraying opening and an in-ground pressure sensor are arranged on the drill bit; the slurry spraying port is communicated with the slurry channel, the gas spraying port is communicated with the gas channel, the in-ground pressure sensor is connected with the control device through a signal line in the signal channel, and the control device is used for calculating an in-ground pressure control value in real time according to the depth of the drill bit. And the slurry spraying pressure of the slurry spraying opening, the gas spraying pressure of the gas spraying opening and the rotating speed of the drill rod are adjusted according to the underground pressure provided by the underground pressure sensor, so that the underground pressure detected by the underground pressure sensor is smaller than the underground pressure control value. By the adoption of the technical scheme, disturbance to surrounding soil during piling construction can be reduced.
本发明提供了一种搅拌桩地内压力控制系统及其打桩施工方法，其所述控制系统包括控制装置、钻杆和钻头，所述钻杆内设置分别设置有浆液通道、信号通道及气体通道，所述钻头上设置有喷浆口、喷气口及地内压力传感器，所述喷浆口与所述浆液通道相连通，所述喷气口与所述气体通道相连通，所述地内压力传感器通过所述信号通道中的信号线与所述控制装置相连接，所述控制装置用于根据所述钻头的深度实时计算地内压力控制值，并根据所述地内压力传感器提供的地内压力调整所述喷浆口的喷浆压力、所述喷气口的喷气压力以及所述钻杆的转速，从而使得所述地内压力传感器检测到的地内压力小于所述地内压力控制值。采用本发明的技术方案，可以降低打桩施工时对周边土体的扰动。
