Side slope deformation automatic monitoring and early warning apparatus

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. ...

AI Technical Summary

Problems solved by technology

Crack monitoring can only make a qualitative evaluation of slope instability and damage, with a strong personal subjective consciousness; for ground observation network monitoring, the deployment of the monitoring network is troublesome, and control piles and observation piles need to be arranged, and the measurement accuracy is not high , the monitoring time interval for slope deformation is uncertain, and it cannot be monitored continuously for a long time; although GPS monitoring slope displacement can provide fast and all-weather monitoring, the monitoring cost is relatively high, and the monitoring and utilization of road slopes is bound to be uneconomical
