Description

technical field [0001] The invention belongs to the technical field of foundation pit excavation monitoring, and in particular relates to a device suitable for rivers around foundation pits, which adopts a variable resistor controlled by a liquid level to realize horizontal displacement and settlement monitoring and early warning of deep soil in the river bed of the river. Background technique [0002] With the further development of the economy and society, cities began to build high-rise buildings, railway stations and other buildings, and at the same time use the underground space to build subways, parking lots, etc. The construction of these facilities is inseparable from the construction of foundation pits, especially ultra-deep and super-large foundations. Pit construction. The construction of deep foundation pit needs to fully consider the impact of the surrounding environment on the construction and the impact of the construction on the surrounding environment. When...

Problems solved by technology

[0004] In order to overcome the shortcomings and deficiencies of existing soil deformation monitoring devices, the present invention provides a liquid level control variable resistance type omni-directional telescopic device for monitoring deep soil deformation, which realizes the deep soil in the river channel during the whole process of foundation pit excavation. The monitoring and early warning of the horizontal displacement and settlement of the body can provide more accurate monitoring data for the excavation project of the foundation pit, and provide a strong support for the study of the deformation law of the deep soil in the river channel; it can not only be applied to the monitoring of the foundation pit project close to the river channel, but also has Intelligent early warning function can ensure the safety of foundation pit engineering construction
