Description

Technical Field

[0001] This utility model relates to the field of settlement monitoring, and in particular to a settlement prediction device for large-size pipe jacking crossing dikes. Background Technology

[0002] The overall stability of dams has always been a key concern in water conservancy and hydropower projects, as it relates to the safety of people's lives and property and the construction of the national economy. In order to ensure the stable operation of dams, it is necessary to monitor the settlement of dams in order to take preventive measures.

[0003] For related technology, please refer to Chinese patent application CN112595287B, which discloses a ground subsidence monitoring device, comprising: a rubber pipe, a telescopic airbag, a fixing part, a weight, and a telescopic air tube; the rubber pipe is inserted into a detection hole and filled with concrete; multiple telescopic airbags are nested at certain intervals on the outer wall of the rubber pipe; the fixing part is connected between the telescopic airbags, and the fixing part has a channel communicating with the inside of the rubber pipe. The concrete in the rubber pipe flows out from the channel to the outer side of the fixing part and the wall of the hole to be detected. After the concrete solidifies, the fixing part adheres to the hole to be detected.

[0004] Regarding the aforementioned technologies, this stratum settlement monitoring equipment can only monitor the settlement of one monitoring point. When monitoring the settlement of the entire stratum, each monitoring point needs to be equipped with a complete settlement monitoring unit, which is relatively complex in structure, requires a lot of manpower, and is inconvenient to operate.
