When building construction is carried out, the ground settlement of a construction site needs to be detected, a worker moves the sleeve 1 to the site to be detected, the sleeve 1 is vertical to the horizontal plane, the worker moves the sleeve 1 vertically downwards, the sleeve 1 drives the inner rod 4 and the extrusion piece 6 to move downwards, the extrusion piece 6 drives the trigger post 23 to move downwards, the trigger post 23 contacts with the ground and stops moving, the trigger post 23 presses the limit hemisphere 24 into the extrusion piece 6 along with the downward movement of the extrusion piece 6, springs adjacent to the limit hemisphere 24 are compressed, the limit hemisphere 24 loses contact with the trigger post 23 and releases the limit of the limit hemisphere, the trigger post 23 moves upwards relative to the extrusion piece 6, the trigger post 23 presses two extrusion pieces 25 to two sides respectively, and stretches a tension spring between the two extrusion pieces 25, the extrusion pieces 25 push the adjacent limit pieces 26 to move, the springs adjacent to the limit pieces 26 are compressed, the limit pieces 26 lose contact with the extrusion piece 6, at the moment, the trigger post 23 completely enters the extrusion piece 6 to contact with the ground, and the extrusion pieces 25 move to a position coplanar with the side surface of the extrusion piece 6, and stop.
After the extrusion piece 6 contacts with the ground, a worker fixes the sleeve 1 by using a tool, then rotates the locking swivel 20 clockwise, the locking swivel 20 drives the locking ball 22 to rotate, the sleeve 1 extrudes the locking ball 22 into the locking swivel 20 and compresses springs adjacent to the locking ball 22, the locking ball 22 follows the locking swivel 20 to rotate and enters grooves adjacent to the sleeve 1 under the action of the adjacent springs, the locking swivel 20 drives the locking piece 21 to move to the outer side of the sleeve 1 through magnetic force while the locking swivel 20 rotates, the locking piece 21 loses contact with the inner rod 4 and limits the inner rod, and at the moment, the worker stops rotating the locking swivel 20.
After the locking piece 21 loses contact with the inner rod 4, the inner rod 4 and the extrusion piece 6 move downwards under the action of gravity, meanwhile, the inner rod 4 is not in contact with the inner wall of the sleeve 1 under the action of repulsive force between the magnetic ring 3 and the magnetic strip 5, but when the magnetic strip 5 moves to the lower side of the magnetic ring 3, repulsive force of the magnetic strip 3 to the magnetic strip 5 acts on the inner rod 4, so that extrusion force of the extrusion piece 6 to the ground is increased, and a measurement result is inaccurate, and the solution is as follows: when the magnetic stripe 5 is subjected to the repulsive force of the upper magnetic ring 3, the inner rod 4 moves downwards relative to the extrusion piece 6, the spring between the extrusion piece 6 and the inner rod 4 is compressed, the extrusion piece 6 drives the detection through hole 17 to move upwards relative to the inner rod 4, the detection through hole 17 is communicated with the weight unloading through hole 171, at the moment, the push rod 19 on the right side moves upwards relative to the adjacent hydraulic cylinder 18 under the action of the adjacent tension spring, the volume of the adjacent constant weight chamber 191 is increased, hydraulic oil in the weight adjusting chamber 161 is pumped out through the guide pipe and the weight unloading through hole 171, the volume of the hydraulic oil in the weight adjusting chamber 161 is reduced, the piston 16 moves downwards, the pressure of the inner rod 4 to the extrusion piece 6 is reduced, the inner rod 4 moves upwards under the action of the spring between the inner rod 4 and the extrusion piece 6, the extrusion piece 6 drives the detection through hole 17 to move downwards relative to the inner rod 4, and the detection through hole 17 is out of communication with the weight unloading through hole 171.
When the hardness of the ground below the extrusion piece 6 is different, the extrusion piece 6 is caused to deviate, the extrusion piece 6 drives the inner rod 4 to deviate, the inner rod 4 contacts with the inner wall of the sleeve 1, at the moment, the pressure of the inner rod 4 to the extrusion piece 6 is reduced due to the friction force between the inner rod 4 and the sleeve 1, at the moment, the inner rod 4 moves upwards under the action of a spring between the inner rod 4 and the extrusion piece 6, the extrusion piece 6 drives the detection through hole 17 to move downwards relative to the inner rod 4, the detection through hole 17 is communicated with the weight supplementing through hole 172, at the moment, the push rod 19 on the left side moves downwards relative to the adjacent hydraulic cylinder 18 under the action of an adjacent spring, the volume of the weight fixing chamber 191 is reduced, hydraulic oil in the weight fixing chamber 191 is conveyed into the weight adjusting chamber 161 through a conduit and the weight supplementing through hole 172, the volume of the hydraulic oil in the weight adjusting chamber 161 is increased, the piston 16 moves upwards, the volume of the hydraulic oil in the weight adjusting chamber 161 is increased, and then the pressure of the inner rod 4 to the extrusion piece 6 is increased, in the process, the inner rod 4 moves downwards relative to the extrusion piece 6, the detection through hole 17 and the weight supplementing through hole 172 is lost, the distance between the detection inner rod 4 and the weight of the extrusion piece 6 is detected, and the extrusion piece 6 is always kept consistent, and the accuracy of the pressure of the extrusion piece 6 is improved.
