Problems solved by technology

[0004] During the monitoring process of the above technology, it is necessary to drill holes on the road to form a monitoring hole, and the monitoring hole will only close the hole in the later stage. Although there are holes in the structural layer of the road, and because the structural layer of the road has a certain rigidity The monitoring hole is not easy to be damaged, so conventional monitoring technology is not suitable for direct monitoring of underground subsidence of urban roads and cannot give early warning

Embodiment 1

[0038] Embodiment 1: An automatic early warning and monitoring device system for underground subsidence of urban roads, such as figure 1 As shown, it includes an above-ground early-warning information receiver 1 and an underground early-warning device 2; the underground early-warning device 2 is arranged below the road structure layer, and the above-ground early-warning information receiver 1 and the underground early-warning device 2 are connected wirelessly. When the road subsides, The underground early warning device 2 starts automatically, and transmits the information of the subsidence to the ground early warning information receiver 1, so that the subsidence information of the road can be monitored in real time.

[0039] Such as figure 2 and image 3 As shown, the underground early warning device 2 includes a cylindrical main body 21 and a cavity 22 inside the main body 21, the cavity 22 is located at the upper half of the main body 21; the inner wall of the cavity 22...

Embodiment 2

[0045] Embodiment two: if Figure 4 As shown in Fig. 1, surface monitoring in conventional urban engineering requires drilling a monitoring hole on the road, passing a threaded steel bar through the monitoring hole to the underground of the road, and then pouring concrete to fill it, so that the steel bar and the road form an integral body. Observe the deformation of the road surface, but drilling monitoring holes will cause damage to the road, so a vertical steel pipe 4 is inserted on the main body 21, the steel pipe 4 is at the axis of the main body 21, and the steel pipe 4 runs through the main body 21, the cavity 22 and the The drop body 3 and the steel pipe 4 can be inserted through the steel bar, so that there is no need to drill additional monitoring holes and reduce damage to the road; The side wall is rotationally connected, and the transverse axis 27 does not pass through the steel pipe 4, so as to avoid affecting the insertion of the reinforcing bar.

Abstract

The invention discloses an automatic early warning and monitoring device system for urban road underground collapse, and belongs to a road geological disaster monitoring technology. According to the technical scheme, the system is characterized by comprising an underground early warning device and an overground early warning information receiver; a signal transmission module, a displacement sensor, a power supply and a power switch are fixedly connected to the side wall of the cavity in the body and are connected in series through wires; a horizontal transverse shaft is arranged in the sealedcavity, the two ends of the transverse shaft are rotationally connected with the inner wall of the cavity through bearings, and a displacement line is wound on the transverse shaft; a containing groove is formed in the lower end of the body, a falling body is arranged in the containing groove, one end of the displacement line is connected with the power switch, the other end of the displacement line enters the containing groove to be fixedly connected with the falling body, and the displacement sensor is close to the displacement line. The problem that the conventional monitoring technology isnot suitable for directly monitoring the underground collapse of the urban road is solved, and the effect of early warning before the pavement collapse is formed is achieved.

Description

technical field [0001] The invention relates to a road geological disaster monitoring technology, in particular to an automatic early warning and monitoring device system for underground subsidence of urban roads. Background technique [0002] With the continuous advancement of urbanization in our country, affected by various urban engineering constructions, especially during the peak period of urban rail transit construction, and the complex underground pipelines underground in urban roads, urban roads frequently collapse, causing serious damage to road traffic and people's lives. Property caused great loss. Due to its own structural characteristics, urban roads have the characteristics of concealment, suddenness, great destructiveness, and difficulty in monitoring. [0003] Now you can refer to the Chinese invention patent with the authorized announcement number CN103558639B, which discloses a ground subsidence monitoring method. The induction ring and the magnetic sensor ...
