Therefore, the automobile is easy to have traffic accidents on the mountain road, and the automobile is damaged if the traffic accidents are light, so that the traffic jam is caused; if the weight is heavy, the car will be damaged.
In the prior art, the guard rails of mountain roads mainly include rigid concrete guard rails, semi-rigid corrugated guard rails, flexible cable guard rails, and the like. Because the concrete guard rail is of a rigid structure, the concrete guard rail has small deformation capacity and basically does not absorb energy, and under the impact action of an automobile, the automobile is easy to deform to cause injuries and deaths to the automobile and people; in the semi-rigid waveform guard rail, because the waveform guard rail has small deformation and basically has no buffering capacity, under the impact action of an automobile, a waveform plate is easy to break to cause the automobile to rush into a reverse lane or fall, and the broken waveform guard rail is easy to pierce the automobile to aggravate casualties. The conventional flexible cable guard rail has a small intercepting effect because the cable has a limited energy absorption. Although the improved flexible cable protective guard is additionally provided with the spring buffer, the vehicle is easy to bounce after being intercepted, and secondary damage can be caused to subsequent vehicles and personnel.

At least two support frames 110 are provided, and at least two support frames 110 are arranged in parallel at intervals. The energy consumption assembly 130 includes a first connection line 131 and an energy consumption member 132. The first connecting line 131 is connected between two adjacent supporting frames 110, and the barrier net 120 is located between two adjacent supporting frames 110 and connected to the first connecting line 131. The energy consumption member 132 is disposed on the first connection line 131, and is used to dissipate a tensile force of the first connection line 131.
In the installation process of the mountain road guard rail 100, firstly, two support frames 110 are installed at the protection positions of the mountain road; then, connecting both ends of the barrier net 120 with the two support frames 110, so that the barrier net 120 is opened; finally, the first connecting line 131 is connected to the barrier net 120, and after being tensioned, both ends of the first connecting line 131 are connected to the energy consumption member 132. In use, when a vehicle is out of control to hit the mountain road guard rail 100, firstly, the vehicle contacts the guard rail net 120; then, under the further impact of the automobile, the guardrail net 120 starts to deform greatly, and due to the supporting function of the supporting frame 110, the guardrail net 120 is gradually tightened; then, as the fence net 120 is continuously tightened, the tension of the first connecting line 131 is increased, and the energy consumption member 132 starts to consume energy to dissipate the tension of the first connecting line 131; finally, the energy is exhausted and the vehicle is stopped and wrapped in the barrier net 120. The mountain road protective guard 100 can absorb the impact force of an out-of-control vehicle, improve the protective effect on the out-of-control vehicle, be beneficial to avoiding the vehicle from being overturned and falling or popping out the vehicle which endangers the road, reduce the casualty accidents of the vehicle and personnel, and further improve the driving safety of the mountain road.
Optionally, the energy consumption member 132 and the first connection line 131 are disposed on the support frames 110 in multiple manners, the first is that the number of the first connection lines 131 is two, two ends of the energy consumption member 132 are respectively connected to the two first connection lines 131, the two first connection lines 131 are connected between the two support frames 110, and the guardrail net 120 is disposed on the first connection lines 131. Alternatively, the first connection line 131 is one, one end of the first connection line 131 bypasses the two support frames 110, and two opposite ends of the first connection line 131 are respectively connected to two opposite ends of the energy consumption 132.
Specifically, referring to fig. 1 and fig. 2, the first connecting wires 131 respectively surround and are connected to two adjacent supporting frames 110.
