Perpendicularity self-correcting recoverable steel casing system for karst cave area and correcting method
The invention relates to the field of steel casing construction, and provides a perpendicularity self-correcting recoverable steel casing system for a karst cave area and a correcting method. The system comprises a recovering part, a connecting part, a standard part and a control unit; the recovering part, the connecting part and the standard part respectively comprise a steel casing and a connecting piece; the lower ends of the recovering part, the connection part and the standard part are provided with correcting assemblies used for adjusting perpendicularity; and the control unit is used for controlling movement of the correcting assemblies; The method comprises the steps that the correcting assemblies send position information to the control unit in real time; the control unit calculates the perpendicularity of each component; when the perpendicularity is abnormal, correction is performed; and recovery is performed by the recovering part. The problem that pile foundation hole forming in a water-rich soft stratum is prone to skewing can be solved, self-feedback and self-correction of the perpendicularity of the steel casings can be achieved through ultrasonic positioning in the sinking process of the steel casings, and the perpendicularity of formed holes is guaranteed; and a recoverable structure is arranged on a first steel casing and can be separated and recovered after grouting is completed.
本发明涉及钢护筒施工领域，提供了一种溶洞区用垂直度自矫正可回收钢护筒系统及矫正方法；所述系统包括回收部、衔接部、标准部及控制单元：回收部、衔接部、标准部均包括钢护筒和连接件；回收部、衔接部和标准部的下端均设置有用于调整垂直度的矫正组件；控制单元用于控制所述矫正组件的运动。所述方法包括矫正组件实时发送位置信息到控制单元；控制单元分别解算出各部件的垂直度；垂直度异常时进行矫正；回收部的回收。本发明可解决富水软弱地层的桩基成孔容易发生歪斜的问题，可在钢护筒下沉过程中通过超声波定位实现对其垂直度的自反馈和自矫正，保证成孔的垂直度；并在第一钢护筒上设置可回收结构，在注浆完成后可分离回收。
