Problems solved by technology

[0002] Foundation pit monitoring is an important link in the construction of foundation pit engineering. Observe and analyze the work, and feedback the monitoring results in time, predict the deformation and stable state development after further construction, and judge the degree of impact of the construction on the surrounding environment according to the prediction, to guide the design and construction, and realize the so-called information construction. Existing foundation pit monitoring has a variety of monitoring technologies and signal transmission and processing methods. Due to the advancement of equipment and information equipment, there is a lack of equipment that uses fixed-point coordinates to automatically monitor foundation pit surface data and uses data comparison for monitoring. In the past, Monitoring often takes a lot of time for technicians, resulting in the inability to quickly obtain data. Manual monitoring often has a small monitoring coverage density, which cannot meet the requirements of early warning, and cannot guarantee the personal safety of surveyors, and cannot realize automatic control.

Abstract

The invention discloses a foundation pit automatic monitoring control and a construction method thereof. The foundation pit automatic monitoring control comprises a foundation pit, a central calibration contrast device is arranged in the middle position of the bottom wall of the foundation pit, sampling fixed-point detection devices are arranged symmetrically on the two sides of the bottom wall ofthe foundation pit, a plurality of side wall data detection devices which are uniformly distributed are arranged in the two side walls of the foundation pit, installation functional frames matched with the side wall data detection devices are arranged on one sides of the side wall data detection devices, infrared contrast calibration boxes matched with the sampling fixed-point detection devices are arranged in the installation functional frames, signal receivers are arranged at the top ends of the infrared contrast calibration boxes, and signal transmitters matched with the infrared contrastcalibration boxes are arranged at the bottom ends of the infrared contrast calibration boxes. The foundation pit automatic monitoring control has the beneficial effects that it is effectively guaranteed that central positioning equipment which is embedded and has reference is adopted at the bottom of the foundation pit in the whole use period, and thus the monitoring of the equipment can be timelyand accurate obviously.
