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

Wherein, described support steel is fixed in the motionless Rock And Soil of slope monitoring point both sides; Described can is screwed on the horizontal steel pipe of support steel; Described photoresistance and pointolite are separately fixed on the both sides inwall of described can; The described chi that is in the light between described photoresistance and pointolite, and passes the import and export of described can, is inlayed outward be fixedly connected with described iron by screw; Described electric current wireless senser is mounted on can top by data line and described photoresistance; Described warning device is arranged on the road bottom side slope.
Described support steel is made up of with the horizontal steel pipe being connected supported on both sides steel pipe the supporting steel pipe be fixed in the motionless Rock And Soil in both sides, monitoring point, and each interface is all weldingly connected; The horizontal steel pipe of described support steel is provided with the screw of fixing described can.Motionless for making described support steel be fixed on better in side slope, supporting steel pipe bottom welding has iron plate and imbeds the motionless Rock And Soil degree of depth and is greater than 10cm, and mixes earth with cement and build fixing.
Described can is closed, light tight and corrosion resistant stainless steel can, can side be provided with can just make described in be in the light that chi is without hindrance freely to rotate and the import and export of movement.Described photoresistance is highly sensitive photoresistance; Described pointolite is concentrate the pointolite launching high-brightness light.Described photoresistance and pointolite are separately fixed on the inwall of can both sides, adjacent import and export one end, and are connected with direct supply respectively.
The described chi that is in the light is made up of transparent hard tempered glass, it scribbles a layer pigment, and the transparency of the chi that makes to be in the light gradually changes with scale; Described chi one end of being in the light has circular hole, can be embedded into described iron upper end and penetrate screw and fix.
Described can is hard straight solid iron, and lower end is that the soil body is conveniently inserted in tip, and upper end is fracture, and fracture two ends have screw, and be in the light described in just embedding chi and screw are fixed; In the vertical domatic insertion soil body of described iron, embedded depth is greater than 2m, and soil body outer length is 0.5m, and described iron top is is just imported and exported described can, and distance is 0.5m.
Monitoring of Slope Deformation for monitoring point, is respectively furnished with monitoring point in side slope upper, middle and lower with described iron, and numbers each monitoring point, then installs monitoring device; And be connected by electric wire with the device of three in side slope while that bottom side slope, road being provided with warning device.
Beneficial effect of the present invention: the present invention provides a kind of displacement monitoring technology of robotization to slope of highway.The iron inserting the soil body is driven to move by slope ground displacement body, thus the chi that makes to be in the light in can moves, the light intensity that the transparency difference at the different scale place of the chi that is in the light causes pointolite to be irradiated in photoresistance through the chi that is in the light changes, the deflection of slope soil is sent to monitoring station with the form of curent change by electric current wireless senser, can be calculated deflection and the rate of deformation of side slope by current data real-time in monitoring station.The present invention can save the workload of a large amount of traditional slope monitoring, realizes the round-the-clock automatic record of slope deforming, not the impact of climate and weather, makes reliable quantitative evaluation to the tendency toward sliding of side slope; And detachably reuse, cost-saving.Can automatic alarm be realized by installing warning device, in hazardous location, in advance warning being made to driving.
