Abstract

The invention discloses a monitoring device and method for horizontal displacement and vertical sedimentation of a foundation pit deep layer. The monitoring device comprises a deformation measuring system, a distance measuring system, a reference point and a data processing system. The deformation measuring system comprises a plurality of deformation detectors embedded in the side wall of a foundation pit and used for measuring horizontal flexural deflection of a soil body on the side wall of the foundation pit in the depth direction. The distance measuring system is used for measuring the distance between the top point of the deformation measuring system and the distance measuring system. The reference point is arranged on the side far away from the side wall of the foundation pit. The data processing system is used for receiving data monitored by the deformation measuring system and the distance measuring system and processing the received data, and horizontal displacement and vertical sedimentation of the foundation pit deep layer are transmitted to a user terminal. According to the monitoring device and method, horizontal displacement and vertical sedimentation of the soil body of the foundation pit deep layer are monitored in real time at the same time, and manual measurement is not needed. The automation degree is high, the monitoring cost is reduced, and the measuring precision and the data reliability are further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a monitoring device and method for deep horizontal displacement and vertical settlement of foundation pits. Background technique [0002] The rapid development of urbanization in my country is facing many severe challenges: shortage of land resources, reduction of green space, explosive growth of urban population, traffic congestion, increase in energy consumption, environmental pollution, rising housing prices and other issues, all of which make vigorous development and utilization of underground Space resources and the expansion of human activity space are becoming more and more urgent. Therefore, the excavation depth of foundation pit engineering is getting deeper and larger, and the technical difficulty is also increasing. [0003] In recent years, many safety accidents have occurred during the construction of some underground projects and foundation...
