Embodiment Construction
[0021] The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings.
[0022] The embodiment of the present invention discloses an automatic monitoring device for foundation pit displacement, including detection equipment and a processor 2 . Such as figure 1 As shown, connecting rods 3 are vertically inserted on the ground at the circumferential edge of the foundation pit, and the connecting rods 3 are arranged at equal intervals along the circumferential edge of the foundation pit. The ends of the connecting rods 3 opposite to the foundation pit are connected with steel wire 4. The wire ropes 4 are staggered above the foundation pit in a grid shape. The protective cover 14 of the monitoring device 1 is connected to the intersection point of the steel wire rope 4, so that the monitoring device 1 is evenly distributed above the foundation pit, so that the monitoring area of the monitoring device 1 cov...

The invention relates to an automatic monitoring device for displacement of a foundation pit and belongs to the field of foundation pit monitoring. The automatic monitoring device comprises monitoringequipment and a processor, wherein the monitoring equipment comprises an infrared dot matrix projector, an infrared camera and a flight time sensor, the infrared dot matrix projector is arranged above the foundation pit and used for emitting infrared structured light to the foundation pit; the infrared camera and the infrared dot matrix projector are arranged at intervals, and the infrared camerais used for receiving infrared structure light reflected by the foundation pit; and the flight time sensor and the infrared dot matrix projector are arranged at intervals, and the flight time sensoris used for judging the distance between different positions on the foundation pit and the flight time sensor. According to the automatic monitoring device, the defect that traditional close-range photography cannot be monitored in real time is overcome, and the signal receiving of the infrared camera and the flight time sensor is not influenced by the ambient brightness, the full-day monitoring of 24 hours can be realized, and the construction safety of the construction site is guaranteed.
Description
technical field [0001] The invention relates to the field of foundation pit displacement monitoring, in particular to an automatic monitoring device for foundation pit displacement. Background technique [0002] With the development of urban construction, major cities in the world have developed and utilized underground space for different purposes, such as multi-storey basements of high-rise buildings, underground railways, underground shopping malls, and various underground civil and industrial facilities. However, the increase in the scale and excavation depth of the foundation pit makes the deformation and stability of the temporary enclosure structure more complicated and prominent, which has become a problem of great concern to the engineering field and municipal management departments. On the one hand, the increase in plane size and excavation depth has caused many new problems, which are difficult to solve based on existing theories and experiences; Traffic has stri...
