Underground diaphragm wall dismantling device and method based on microwave cracking concrete technology
The invention relates to an underground diaphragm wall dismantling device and method based on a microwave cracking concrete technology. The device comprises a dismantling device body, wherein the dismantling device body comprises a microwave power supply, a microwave system, a shielding box body, a lifting propulsion device, a microwave focusing antenna, a twisted waveguide, a laser displacement sensor and a steel bar cutting machine. The method comprises the steps that the laser displacement sensor is used for measuring the distance between the microwave focusing antenna and an underground diaphragm wall, the distance between the dismantling device and the underground diaphragm wall is kept within 1cm through the lifting propulsion device, the underground diaphragm wall is irradiated by utilizing appropriate microwave power until thermal spalling occurs, after concrete spalling is completed, steel bars are cut off by using the steel bar cutting machine, and concrete blocks are removedby using a crane. According to the device and method, the characteristic that high-power density microwaves are used for selectively heating mortar or high-loss reinforcing ribs is utilized, so thatthe concrete is cracked, and controllable non-blasting dismantling of the underground diaphragm wall is realized.
本发明涉及一种基于微波致裂混凝土技术的地下连续墙拆除设备和方法，所述设备包括拆除设备本体，拆除设备本体包括微波电源、微波系统、屏蔽箱体、升降推进装置、微波聚焦天线、扭波导、激光位移传感器以及钢筋切割机；所述方法利用激光位移传感器测量微波聚焦天线至地下连续墙距离，通过升降推进装置保持拆除设备与地下连续墙之间距离在1cm以内，利用合适的微波功率对地下连续墙进行照射，直至其发生热剥落，待混凝土剥落完成，用钢筋切割机切除钢筋，并用吊机移除混凝土块；本发明所述的设备和方法利用大功率密度微波选择性加热砂浆或高损耗加强筋的特点，使混凝土发生爆裂，实现地下连续墙的可控非爆破拆除。
