Moisture-trapping loess foundation pit anti-slip electric sintering supporting pile
The invention relates to the technical field of foundation pit supporting equipment. A moisture-trapping loess foundation pit anti-slip electric sintering supporting pile comprises a main pile pipe, an upper pile extension pipe, a core pipe, a steel wire electrode, an expansion anchor top and an expansion anchor top brush ball; the main pile pipe is a plastic steel circular pipe, a plurality of electrode holes are formed in the side face of the main pile pipe, the upper end of the main pile pipe is detachably connected with the upper pile extension pipe, the lower end of the main pile pipe isprovided with the expansion anchor top, the expansion anchor top is composed of an anchor point, at least two anchor rods and an anchor rod hinge shaft, the anchor point is installed at the end of thelower end of the main pile pipe, the anchor rods are symmetrically and obliquely arranged along the central axis of the main pile pipe, and anchor grooves are formed in the side wall of the main pilepipe at the anchor rods; and the core pipe is a cylindrical plastic part and sleeves the upper strut pipe, and the core pipe is provided with an electrode socket, a socket connecting lead and a brushpush rod. According to the moisture-trapping loess foundation pit anti-slip electric sintering supporting pile, under the condition that the earthwork engineering quantity is not increased, the supporting and reinforcing effect close to reinforced soil is achieved in a sintering mode of an electric arc breakdown soil layer, and the safety of the foundation pit operation in the wet-trapping loessenvironment is effectively improved.
本发明涉及基坑支护设备技术领域；湿陷性黄土基坑防滑塌电烧结支护桩，包括主桩管、上接桩管、芯管、钢丝电极、膨胀锚顶和膨胀锚顶电刷球；其中，主桩管为塑钢圆管，侧面设置有多个电极孔，其上端与上接桩管可拆卸连接，下端设置有膨胀锚顶，膨胀锚顶由安装在主桩管下端端部的锚尖、至少两个锚杆和锚杆铰轴组成，锚杆沿主桩管中轴线对称倾斜布置，主桩管侧壁在锚杆处设置有锚槽；芯管为圆柱状塑料件，套装在上接桩管内，安装有电极插座、插座连接导线和电刷推杆；本发明在不增加土方工程量的情况下，通过电弧击穿土层烧结的方式，实现了接近加筋土的支护加固效果，有效提高了湿陷性黄土环境下基坑作业的安全性。
