Abstract

The invention discloses an automatic deformation monitoring equipment for a subway foundation pit, which relates to the technical field of foundation pit construction monitoring, and comprises a base, the base is arranged horizontally, and a column is fixedly connected to the center of the top of the base, and the column is a vertical column. The top of the column is movable and a telescopic monitoring rod is arranged horizontally. The telescopic monitoring rod includes a plumb weight. On the monitoring rod, a monitoring mechanism is provided at the bottom of the other end of the telescopic monitoring rod away from the column. When the device works before each measurement in the present invention, the self-position coordinates of the device are first corrected through the monitoring point, and the hydraulic mechanism set up works to adjust the angle of the telescopic monitoring rod to determine the uplift height of the foundation pit. The deformation data of all detection points at the bottom of the pit are recorded and measured, and then monitored by the detection mechanism.

Description

Technical field [0001] The present invention relates to the field of excavation construction monitoring technology, specifically to a subway excavation automated deformation monitoring equipment. Background [0002] Urban subway is a hot spot for infrastructure investment in China in recent years, and vigorously developing urban subway has become the focus of municipal construction in large and medium-sized cities. Most of China's subways are buried more than ten or twenty meters deep underground, or even deeper, and it is indispensable to ensure the safety of construction. Statistical analysis found that any one foundation pit accident was invariably associated with poor monitoring or inaccurate forecasting of dangerous situations. Therefore, the safety and stability of the foundation pit determines whether the entire project construction can be successfully completed, and the displacement monitoring related to the foundation pit occupies a very important position in the constru...
