Description

Technical Field

[0001] The utility model relates to the technical field of sinking displacement monitoring, in particular to a sinking displacement monitoring device for an underground space top plate. Background Art

[0002] Underground space refers to the space below the ground surface, mainly for buildings. It has a wide range, such as underground shopping malls, underground parking lots, subways, mines, military, sea tunnels and other building spaces. During the construction of underground space, the main structure is constructed in the underground space, and then the top plate is laid on the main structure, and then the top plate is filled. In this process, a corresponding displacement monitoring device is needed to monitor the downward displacement of the top plate. When the displacement is too large, the construction needs to be stopped and corresponding reinforcement measures need to be taken. When the existing displacement monitoring device monitors the top plate, it usually uses a displacement sensor to monitor the displacement. When the displacement is too large, an electrical signal will be sent to the control room, and then the control room personnel will command the workers to stop work and reinforce. This method has a certain hysteresis. For example, when the deformation is too large, it takes a long time from the control room personnel commanding the workers to stop work to reinforcement. During this period of time, the top plate may continue to sink, which makes the reinforcement process particularly cumbersome. Utility Model Content

The support plate 3 can be customized according to the shape of the underground space roof, so that the upper surface of the support plate 3 matches the lower surface of the underground space roof.

[0020] A telescopic member 6 is installed on one side of the assembly plate 1. The telescopic member 6 adopts a hydraulic cylinder. The telescopic end of the telescopic member 6 is fixedly connected to the reinforcing plate 7. The reinforcing plate 7 can pass through the clearance hole 4 of the assembly plate 1. A monitor is also included. The monitor controls the connection of the telescopic member 6. When the monitor detects that the top plate of the underground space has settled and displaced, when the displacement exceeds the set value, the monitor can control the telescopic member 6 to drive the reinforcing plate 7 to rise, so as to support the top plate of the underground space through the reinforcing plate 7, slowing down or eliminating the trend of the top plate of the underground space to continue to sink.

[0021] Specifically, the monitor includes an internal threaded tube 13, which is fixed on the lower side of the center hole 12 of the support plate 3, and the internal thread of the internal threaded tube 13 is connected to a threaded collar 14, and a mounting column 16 is installed in the threaded collar 14, and a displacement sensor 17 is fixedly connected to the top of the mounting column 16, and the displacement sensor 17 passes through the center hole 12. The lower side of the threaded collar 14 is fixedly connected to an adjustment column 15. The threaded collar 14 can be easily rotated by adjusting the column 15, thereby changing the position of the threaded collar 14 in the internal threaded tube 13, thereby changing the height of the displacement sensor 17, so that the displacement sensor 17 can contact the lower surface of the underground space top plate. In addition, the displacement sensor 17 is a prior art, and how the displacement sensor 17 controls the telescopic member 6 is also a prior art, which will not be repeated here. At the same time, a buzzer can be installed on the lower side of the support plate 3, and the displacement sensor 17 controls the connection buzzer. When the monitor detects that the underground space top plate has settled and displaced, when the displacement exceeds the set value, the displacement sensor 17 sends an electrical signal, so that the buzzer sends a warning. How the displacement sensor 17 controls the buzzer is also a prior art, which will not be described in detail here. In addition, the buzzer is not drawn in the figure.

A plurality of nozzles are installed on the drain pipe 97. When the reinforcing plate 7 is rising, the piston rod 93 is also raised by the pull rope 100, and the piston 92 is also raised following the piston rod 93. During the rising process of the piston 92, the solution 96 flows out from the drain pipe 97 and enters the transparent cover 94 through the water inlet pipe 98. When the color-changing medium 95 contacts the solution 96, it changes color, thereby achieving a warning effect. In this embodiment, the solution is water, and the color-changing medium 95 can be anhydrous copper sulfate or anhydrous cobalt chloride. Of course, there are other types of combinations of color-changing media 95 and solution 96 in the prior art, which are not listed here.
