Open land combined foundation pit excavation monitoring and early warning system suitable for high slope and river channel double steps and operation method of open land combined foundation pit excavation monitoring and early warning system

Abstract

An open land combined foundation pit excavation monitoring and early warning system suitable for a high slope and river channel double steps comprises an unmanned aerial vehicle, a soil body displacement monitoring device and a high slope sliding monitoring device, the soil body displacement monitoring device is located in a river channel, and the high slope sliding monitoring device is located in the high slope; the soil displacement monitoring device comprises a steel shell, a center rod piece, a fixing bolt, a transmission antenna, a laser lens, an anchoring device, a threaded opening, a limiting baffle, a rotating shaft, a piston, a hydraulic five-way valve, an anchoring horizontal pile, a horizontal displacement monitoring device, a power source, an ampere meter, data transmission equipment and a drill bit; and the high slope sliding monitoring device comprises a positioning rod, a sliding surface monitoring unit, a high-strength spring, a guide rod, a steel ejector pin, a pressure position sensor and an upper transmission unit; and an infrared thermal imaging camera and a laser range finder are installed on the unmanned aerial vehicle. The invention further provides an operation method of the monitoring and early warning system. The system has an intelligent early warning function, and the safety of foundation pit engineering construction can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of foundation pit excavation monitoring, and in particular relates to a system and an operation method for realizing foundation pit excavation monitoring and early warning, which are applicable to complex geological conditions of high slopes and double steps of river courses, and adopt the idea of ​​combining open space and ground . Background technique [0002] With the further development of my country's large-scale infrastructure construction, the use of underground space has attracted more and more public attention. Many cities have successively built underground public facilities such as subways and underground expressways. The construction of these facilities is inseparable from foundation pit engineering. Due to the substantial increase in the density of buildings within the city and the increasingly complex geological environment, many foundation pits are close to large buildings, mountains and river...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the fact that the existing foundation pit monitoring system and its operation method cannot monitor the deformation of high slopes and rivers, or the deformation monitoring of high slopes and rivers is less, imprecise, and not real-time, and cannot be used for high deviation Under the condition of high pressure, the monitoring of foundation pit engineering can realize the monitoring and early warning of foundation pit excavation under the complex geological conditions of high slope and river channel double steps, and the foundation pit engineering detection under high slope bias condition The blank of the system, the present invention provides an open space combined foundation pit excavation monitoring and early warning system and its operating method applicable to high slopes and double steps of the river, which can effectively overcome the shortcomings of the above-mentioned foundation pit engineering monitoring system and its operating method
