Embodiment Construction

[0017] Below in conjunction with accompanying drawing, structure and installation steps of the present invention are further described:

[0018] Such as figure 1 Shown is the main structure of the device, which includes: a closed and light-tight iron box, one side of the iron box is provided with an entrance and exit just enough to allow the light-blocking ruler to rotate and move freely without hindrance; at the end close to the entrance and exit A photoresistor and a point light source are respectively fixed on the inner walls of both sides of the iron box, and are respectively connected to a DC power supply; outside the iron box, a power supply wireless sensor is installed on the upper end of the side of the photoresistor; the light-blocking ruler passes through the entrance of the iron box The outlet and the outside are fixedly connected with the iron rod inlay by screws.

[0019] Such as figure 2 As shown, it is the main structure of the steel support. The supporting s...

Abstract

The invention discloses a deformation automatic monitoring and early warning apparatus applied to road side slopes, comprising a steel support (1), an iron box (2), a point light source (5), a photoresistor (6), a light blocking ruler (4), an iron pole (7), a current wireless sensor (10), and a warning apparatus (11) installed beside a road on the bottom of a side slope. According to the invention, side slope deformation drives the iron pole and the light blocking ruler to move with a same amplitude, and the transparency at different scales of the light blocking ruler is different, which causes the light intensity of the point light source irradiating onto the photoresistor through the light blocking ruler to change; the instantaneous deformation of side slope soil bodies is sent to a monitoring station through the current wireless sensor in a current change mode. The upper section, central section and lower section of a side slope are meanwhile provided with the apparatus, thereby realizing all-weather automatic monitoring of side slope local and whole deformation and deformation rates; in addition, the warning apparatus installed beside a road can give an alarm in advance to vehicles in side slope dangerous sections.

Description

technical field [0001] The invention relates to the fields of geotechnical engineering and disaster prevention and mitigation engineering, in particular to a monitoring and early warning device for road slope deformation in the field of traffic engineering. Background technique [0002] Slope instability and landslides have become a major safety hazard in mountainous highway traffic. The occurrence of slope instability and landslide does not occur in an instantaneous time period, but develops from creeping to unstable sliding after a certain period of accumulation of instability factors. The continuous monitoring of slope deformation, deformation rate, and deformation development trend in each period is the core of evaluating whether a slope can produce destructive landslides, and thus timely and safely disposing of the slope. Traditional slope monitoring technologies mainly include: crack monitoring, ground observation network monitoring, and GPS displacement monitoring. ...
