Problems solved by technology

[0002] Large-scale loaded vehicles usually have a load of more than 10 tons. During the running of the vehicle, due to the large load, the brakes often experience high temperature and lockup, especially on long downhill roads. Due to frequent braking, brake failure The thermal attenuation is extremely serious, and brake failure often occurs. Due to the long downhill section, the vehicle will continue to passively accelerate with the brake failure, and finally rush out of the guardrail, causing extremely serious traffic accidents. The existing method is Build a buffer corridor at the downhill position of the road. The buffer corridor is a simple sandstone structure. By sinking the wheels, the adhesion of the wheels is reduced, and the effect of slowing down is achieved. However, we often find that staying in the buffer corridor The reason for the rollover accident of the loaded vehicle on the road is that due to the serious subsidence of the ground, the vehicle is seriously tilted to one side, which eventually causes the vehicle to rollover

Embodiment 1

[0035] refer to figure 1 and figure 2The shown passive safety device for municipal roads comprises a concrete layer 1 poured on the ground, the pouring thickness of the concrete layer is 50cm, the longitudinal width of the pouring of the concrete layer is 300cm, and the inside of the concrete layer 1 is poured with Reinforcement cage 2, the upper and lower sides of the reinforcement cage are provided with multiple layers in parallel, and a slope 101 with a slope of 3.5° is formed after the concrete layer 1 is poured. The horizontal length of the concrete layer 1 after pouring is 240 meters, the load of the truck is relatively large, and the braking distance of Xiangyin is also relatively long. After pouring on the slope 101, a sunken foundation pit is formed. 102, the depth of the foundation pit 102 is 14 cm, and the buffer mixture 3 is tiled in the foundation pit 102. The setting of the foundation pit 102 is mainly to fill the buffer mixture 3. When the vehicle is running, ...

Embodiment 2

[0037] refer to image 3 As shown, each layer of reinforcement cage 2 includes a plurality of threaded steel bars arranged in a horizontal and vertical staggered manner. The diameter of the threaded steel bars is 10mm, and the staggered positions of the threaded steel bars are bound and fixed by steel binding wires. The distance between horizontally adjacent threaded steel bars is 24cm, and the spacing between longitudinally adjacent rebars is 20cm.

Embodiment 3

[0039] The buffer mixture 3 includes 30% medium sand, 25% stones, and 45% melon seeds. When laying flat, it is mixed by mixing equipment before laying; the above-mentioned materials are simple and easy to obtain, and after being stressed, It has good deformation ability and is easy to cooperate with the wheels to achieve deceleration.

Abstract

The invention discloses a municipal road passive safety device and a mounting method thereof. The municipal road passive safety device comprises a concrete layer poured on the ground, a plurality of layers of vertically and parallelly arranged reinforcement cages are poured in the concrete layer, after the concrete layer is poured, a slope surface with the gradient being 3-6 degrees is formed, during vehicle buffer, a vehicle travels from the low end of the slope surface to a high position, and the transverse length of the poured concrete layer is 200-300 m. According to the municipal road passive safety device, the vehicle can be decelerated.

Description

technical field [0001] The invention relates to a municipal road passive safety device and an installation method thereof. Background technique [0002] For large loaded vehicles, the load of the vehicle is usually more than 10 tons. During the running of the vehicle, due to the large load, the brakes often experience high temperature and lockup, especially on long downhill roads, due to frequent braking. The thermal attenuation is extremely serious, and brake failure often occurs. Due to the long downhill section, the vehicle will continue to passively accelerate with the brake failure, and finally rush out of the guardrail, causing extremely serious traffic accidents. The existing method is Build a buffer corridor at the downhill position of the road. The buffer corridor is a simple sandstone structure. By sinking the wheels, the adhesion of the wheels is reduced, and the effect of slowing down is achieved. However, we often find that staying in the buffer corridor The re...
