Description

Technical Field

[0001] The utility model relates to the technical field of earth-rock dam measurement, in particular to a water-pipe type settlement instrument water injection component. Background Art

[0002] The water tube settlement meter is made based on the principle of communicating vessels and is mainly used for vertical displacement monitoring of earth-rock dams. It consists of a settlement probe buried at the measured point, an observation pipe in the observation room, and connecting pipes and protective pipes connecting the two. Among them, the connecting pipes include an inlet pipe, a drain pipe, and a vent pipe. The observation pipe is connected to the settlement probe through the inlet pipe. The vent pipe keeps the air pressure in the settlement probe consistent with the outside world. When the water cup in the settlement probe is filled with water and overflows, the water level in the observation pipe is the same as the water level in the probe water cup. The water level change in the observation pipe measured in this way is the settlement of the measuring point in the dam relative to the observation room.

[0003] There is a water pipe type sedimentation meter water replenishment device with patent publication number CN210975944U. The liquid storage tank set on the top of the dam forms pressure through the height difference, which can provide strong pressure for the filling process and solve the problem of liquid consumption of the sedimentation meter. Compared with manual pressurization, the effect is better and more reliable, and it can save the installation of the pressurization device and save costs. The "cross" shaped support frame is set inside the water inlet pipe and the drainage pipe to avoid the inconvenience of the filling and drainage process caused by the deformation of the dam body for a long time. The deformation of the water inlet pipe and the drainage pipe can be kept relatively stable, thereby maintaining the accuracy of observation.

[0004] Since the device requires a liquid storage tank to be fixed on the dam top, the process is complicated, the cost is high, maintenance is inconvenient, and practicality is poor. Utility Model Content
