A real-time monitoring system for foundation pit deformation

Abstract

The invention provides a real-time monitoring system for foundation pit deformation, which includes multiple ring-shaped fixing frames fixed along the circumference of the inner wall of the foundation pit, wherein two adjacent ring-shaped fixing frames are connected by multiple vertical fixing rods; The annular fixing frame is uniformly equipped with a plurality of foundation pit deformation detection units along its circumference, and each foundation pit deformation detection unit includes a sensor fixing rod, and the sensor fixing rod is respectively equipped with multi-point displacement sensors and pressure sensors, and the sensor fixing rod is installed In the corresponding installation hole drilled on the side wall of the foundation pit, and one end of the sensor fixing rod located at the entrance of the installation hole is fixed on the ring fixing frame, the multi-point displacement sensor and the pressure sensor are respectively connected with the microprocessor signal, and the microprocessor The device is also connected with the display screen and the alarm signal. The invention can realize continuous real-time monitoring of the deformation of the side wall of the foundation pit, can accurately reflect the partial and overall deformation of the foundation pit, and can realize real-time monitoring and timely early warning for dangerous parts of the foundation pit.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a real-time monitoring system for foundation pit deformation. Background technique [0002] During building construction, the foundation pit is usually excavated first, and the deformation monitoring of the foundation pit is one of the essential monitoring items in the construction process. Foundation pit monitoring technology has become an important guarantee method for construction. How to effectively and quickly conduct foundation pit safety monitoring has become a difficult and key point in construction. At present, foundation pit deformation monitoring mostly uses total stations, levels, inclinometers, etc. The instrument requires manual timing measurement and reading, which not only increases the labor intensity, but also makes it difficult to achieve relatively continuous real-time monitoring of the deformation of the side wall of the foundation pit, and it is diffi...

Foundation pit monitoring technology has become an important guarantee method for construction. How to effectively and quickly conduct foundation pit safety monitoring has become a difficult and key point in construction. At present, foundation pit deformation monitoring mostly uses total stations, levels, inclinometers, etc. The instrument requires manual timing measurement and reading, which not only increases the labor intensity, but also makes it difficult to achieve relatively continuous real-time monitoring of the deformation of the side wall of the foundation pit, and it is difficult to accurately reflect the local and overall deformation of the foundation pit at the same time.
