Displacement control device in forced landing deviation rectifying technology and control method
The invention discloses a displacement control device in a forced landing deviation rectifying technology. The displacement control device comprises a scale anchor rod, an anchor head and a sealing head, wherein the sealing head is arranged above an original foundation and a newly-added pile; the lower end of the scale anchor rod penetrates through the sealing head to be anchored with the originalfoundation; the anchor head is anchored with the scale anchor rod and the sealing head; and when the original foundation is settled, the original foundation drives the scale anchor rod, the anchor head and the sealing head to descend until the sealing head presses the newly-added pile, and the original foundation stops settling, so that the settling height of the original foundation is controlled. During construction, one side of the original foundation with small settlement starts to settle until the sealing head presses the newly-added pile, so that the original foundation stops settling and is locked, and at the moment, the settlement amounts of the two sides of the original foundation are kept consistent and are in a horizontal state, so that the purpose of forced landing deviation rectification is achieved. According to the structure, the depth required by the settlement of the side, with small settlement, of the original foundation can be accurately controlled according to the required settlement amount, the original foundation can be in a horizontal state after forced landing deviation rectification is guaranteed, and the device has the beneficial effects of being simple instructure, accurate in control, safe and reliable.
本发明公开了一种迫降纠偏技术中的位移控制装置，包括刻度锚杆、锚头和封头，封头设于原基础和新增桩的上方，刻度锚杆的下端穿过封头与原基础锚固，锚头与刻度锚杆、封头锚固；在原基础沉降时，原基础带动刻度锚杆、锚头和封头下降，直到封头顶压新增桩，原基础停止沉降，实现对原基础的沉降高度进行控制。施工时，使沉降小的原基础的一侧开始沉降，直到封头顶压新增桩，使得原基础停止沉降而被锁定，此时原基础的两侧的沉降量保持一致而处于水平的状态，从而完成迫降纠偏的目的。本结构能根据所需的沉降量准确地控制原基础沉降小的一侧沉降所需的深度，保证原基础在被迫降纠偏后能处于水平状态，具有结构简单、控制准确和安全可靠的有益效果。
