Land subsidence observation device

Abstract

The invention discloses a land subsidence observation device which comprises a reference liquid reservoir arranged at an observation datum point. The reference liquid reservoir is connected to a plurality of observation liquid reservoirs through communicating water pipes; the observation liquid reservoirs are placed at selected subsidence observation points; the reference liquid reservoir and the observation liquid reservoirs are same in capacity and specification and store liquids at standard liquid levels, and water level sensors are mounted in the bottoms, and the water level sensors wirelessly transmit liquid level data to a data acquisition terminal through a wireless transceiving device; the communicating water pipes are arranged above the reference liquid reservoir and the observation liquid reservoirs and separately communicate with the reference liquid reservoir and the observation liquid reservoirs; and buffer plate assemblies are arranged at the bottom of the reference liquid reservoir and the observation liquid reservoirs. According to the device disclosed by the invention, the structural stability is improved, the land subsidence observation data is accurate, the device does not need to be monitored by a specially-assigned person, and subsidence data at multiple points can be collected, so that the detection precision is improved; by arranging the buffer plate assembly, a subsidence observation plate can also keep horizontal on soft soil, and observation is accurate.

Description

technical field [0001] The invention relates to the field of civil engineering, more specifically, it relates to a ground subsidence observation device. Background technique [0002] In the construction of modern urban subways, there are generally unfavorable construction factors such as small and limited sites, complex address conditions, and large excavation depths for foundation pit development. Periodic observation, in order to ensure the quality of monitoring, we will make protective devices to protect the settlement observation device, through the observation of settlement data, and then through software analysis to obtain the change of road ground and pipeline settlement, to achieve the purpose of monitoring and effectively guide the on-site construction operations. [0003] In the existing hydraulic subsidence monitoring system, the water tank is generally connected with the connecting water pipe at the lower part to form a passage, and the connecting water pipe and ...

AI Technical Summary

Problems solved by technology

Therefore, for the subsidence monitoring on the ground, it is necessary to install corresponding brackets to raise the subsidence water tank, or dig out trenches, place Unicom water pipes, and connect the water tanks through the lower Unicom water pipes. In terms of land subsidence, it takes a lot of manpower and material resources, which is very inconvenient, and it is not stable enough, and it is easy to be disturbed by the outside world, such as ground vibration, foreign objects falling into it, etc.
