Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and 2, the present invention provides a technical solution: a protection facility for provincial roads of the highway country comprises a road 3 and a buffer zone 1 arranged at the edge of the road 3, wherein the road 3 is respectively provided with a low risk road section 31 and a high risk road section 32, the buffer zone 1 is arranged at the edge of the low risk road section 31, and one side of the buffer zone 1 far away from the low risk road section 31 is provided with a brush belt 2, the edge of the outer side of the high risk road section 32 is provided with a three-wave-shaped beam and slab guardrail 5, the outer side of the corner bending part of the high risk road section 32 is provided with a two-wave-shaped beam and slab guardrail 7, and the two-wave beam and slab guard bar 7 and the three-wave beam and slab guard bar 5 are connected with each other through a transition section 6, so as to increase the stability of the connection between the two-wave beam plate guardrail 7 and the three-wave beam plate guardrail 5, reduce the possibility of mutual separation between the two-wave beam plate guardrail 7 and the three-wave beam plate guardrail 5, wherein the shrub belt 2 can be protected by setting hard isolation measures such as flower beds and the like under the condition of permission of the land range.

Specifically, as shown in fig. 2, the transition section 6 is fixed at a position 100 meters in front of the edge of the corner bend of the high-risk road section 32, so that the sight distance between two sides is increased when the vehicle is driven to the road section, and the judgment of the driver on the road condition is facilitated.

Specifically, as shown in fig. 1, a shock marking 4 is provided on the buffer zone 1 near the corner bend of the low-risk road segment 31, so as to prompt that the driving vehicle deviates from the normal driving road surface.

Specifically, as shown in fig. 1, the oscillation marking 4 is a concave-convex point-shaped structure, and the height of the oscillation marking 4 is lower than 7 mm, so as to reduce the influence of the oscillation marking 4 on the traveling crane.

Specifically, as shown in fig. 1 and 2, the low risk section 31 and the high risk section 32 are communicated with each other, and the lower end faces of the horizontal ends of the three-wave beam-slab guardrail 5 and the two-wave beam-slab guardrail 7 are overlapped, so that the whole guardrail is kept orderly.

Specifically, as shown in fig. 2, two sides of the top end of the transition section 6 are respectively connected with the top ends of the three-wave-shaped beam-slab guardrail 5 and the two-wave-shaped beam-slab guardrail 7, and the horizontal end of the transition section 6 is of a right-angle trapezoidal structure, so that the stability of the triangular structure at the top of the transition section 6 is higher.

During specific construction, the following steps can be adopted:

s1: cleaning on site;

s2: whether a flower bed or green plants can be set or not is judged according to the risk category and the land utilization range;

s3: drawing a vibration marking line on the edge line of the road of the roadside dangerous section;

s4: and the three wave drops to two wave-shaped beam slab guardrails at the proper positions of the high-risk road section opening.

The working principle is as follows: when the corrugated beam guardrail is used, firstly, the shrub belt 2 is combined with the vibration marked line 4, so that on one hand, the road 3 can obtain sufficient buffering and prompting in the driving process, and on the other hand, the maintenance of a large number of corrugated beam guardrails is reduced; secondly, through the setting of two wave beam slab guardrail 7 for the position field of vision of 32 turning corners meeting of high risk highway section is wider, makes the driving stadia increase, in order to promote the security when meeting, through the connection of the changeover portion 6 between two wave beam slab guardrail 7 and three wave beam slab guardrail 5, through the structural stability of its triangle structure increase connection position, reduces the problem that the separation of junction guardrail is deviate from.
