An automatic alarm device for foundation pit settlement

Abstract

The invention relates to an automatic foundation pit settlement alarm device, comprising a settlement monitoring device and a signal receiving terminal, wherein a balance bar of the balance bar is horizontally connected to a fixed base via a rotating shaft and can rotate along the rotating shaft, a conductive clip ball is arranged at one end of the balance bar, a clip seat matched with the conductive clip ball is arranged at the other end of the balance bar, and the conductive clip ball can be clamped in the clip seat of the adjacent alarm device; an alarm, a power supply, a power sensing switch, an alarm flasher and a wireless signal transmitting device are respectively arranged on the fixed base; and the signal receiving terminal comprises a display screen, a trigger switch and an automatic dialing device. The alarm device is simple in structure, compact in design and convenient to use; a plurality of alarm devices are connected in sequence to accurately and quickly judge the position of settlement in a foundation pit; and the alarm device is low in cost, can effectively monitor and alarm the foundation pit and can be recycled.

Description

technical field [0001] The invention relates to an automatic alarm device for foundation pit settlement, which belongs to the technical field of measuring devices. Background technique [0002] With the rapid development of urban construction, various buildings have sprung up. People are using the upward space while exploring the value of underground space. The construction of high-rise buildings and the development of underground space are inseparable from the excavation of foundation pits. The higher the building construction, the deeper the underground space is developed, the greater the pressure on the foundation pit enclosure. The focus of foundation pit maintenance is the settlement monitoring of the foundation pit. The commonly used foundation pit monitoring is to use a level to read, or to install a GPS foundation pit monitoring network. Using a level to read requires a lot of manpower, material resources and time, and it cannot achieve the purpose of real-time monit...

AI Technical Summary

Problems solved by technology

The commonly used foundation pit monitoring is to use a level to read, or to install a GPS foundation pit monitoring network. Using a level to read requires a lot of manpower, material resources and time, and at the same time it cannot achieve the purpose of real-time monitoring; while installing a GPS foundation pit monitoring network It is necessary to install a large number of expensive GPS receivers around the foundation pit, and at the same time, it must occupy a large amount of construction site. While affecting the site construction, it is often restricted by the air-to-air conditions on site. There are a large number of high-rise buildings or high-power GPS receivers near the construction site. The GPS foundation pit monitoring network will not be available when the high-voltage line of the tower is launched
