The invention discloses a surface subsidence detection device for field construction, the device comprises a threaded cylinder and a cantilever mechanism used for supporting and adjusting the lifting height of the threaded cylinder, one end of the cantilever mechanism is provided with a fixing mechanism used for fixing the device on the surface of the ground, and the interior of the threaded cylinder is slidably connected with a sleeve. A pressing rod is arranged in the sleeve in a sliding mode, a fixing frame is fixedly connected to the bottom of the threaded cylinder, an outer pushing piece used for discharging loosened soil sinking to the pit bottom to the two sides when the pressing rod is pushed downwards is arranged at the bottom of the fixing frame, and the threaded cylinder is driven to rotate by rotating a first pressing plate so that the threaded cylinder can move downwards, until the bottom of the outer pushing piece and the hard part of the sunken part contact, and then the second pressing plate is pressed, the second pressing plate drives the sleeve to move downwards, the sleeve pushes a connecting plate so that the pressing rod can move downwards, the pressing rod pushes the outer pushing piece to move, the outer pushing piece pushes the loosened soil sliding from the sunken bottom to the two sides, and then the sunken bottom is exposed.
Description
technical field [0001] The invention belongs to the technical field related to subsidence detection, and in particular relates to a ground surface subsidence detection device for field construction. Background technique [0002] The current method of measuring road subsidence is to use a simple measuring ruler to extend into the bottom of the subsidence, and the data measured in this way are not accurate enough, which will affect the later repair construction. [0003] For this reason, the application number is CN201910577248.7, which discloses a road subsidence measurement device, including a rectangular plate and a rectangular slider. Together, the right side of the rectangular slider is fixedly connected with a semi-circular block, the upper surface of the semi-circular block is recessed with a circular groove, and a semi-circular ring is arranged in the circular groove, and the size of the semi-circular ring is consistent with the size of the circular groove , the inner...
