Laser measuring device for measuring pile top displacement in compression resistance static load test
The invention discloses a laser measuring device for measuring the displacement of a pile top in a compressive static test, which comprises a laser emitter and a laser receiving unit, the laser emitter and a detected pile synchronously ascend and descend, and the laser receiving unit is fixed in spatial position and is used for receiving laser emitted by the laser emitter. The laser receiving unit comprises a box body, a refractor arranged on the front surface of the box body and a reading plate arranged on the back surface of the box body, the refractor is used for refracting laser to form light spots on the reading plate, and a rear graduated scale is arranged on the reading plate. As the laser transmitter and the detected pile synchronously ascend and descend, position deviation generated by ascending and descending of the laser transmitter and the detected pile can be refracted to the corresponding scales of the reading plate through the refractor to form light spots, displacement of the detected pile can be amplified through the refractor in the process, and the accurate displacement value of the detected pile can be obtained through auxiliary measurement of the reading plate.
本发明公开了一种抗压静载试验桩顶位移测量的激光测量装置，包括激光发射器以及激光接收单元，所述的激光反射器与受检桩同步升降，所述激光接收单元的空间位置固定并用于接收激光发射器发射的激光，所述激光接收单元包括箱体、设置于箱体正面的折射器以及设置于箱体背面的读数板，所述折射器用于折射激光以在读数板上形成光斑，所述读数板上设有后刻度尺。由于激光发射器与受检桩同步升降，因此其升降产生的位置偏差会通过折射器折射到读数板相应的刻度上并形成光斑，其过程中可以通过折射器将受检桩的位移放大并通过读数板加以辅助测量获得受检桩精确的位移值。
