Problems solved by technology

In practice, for the entrance and exit sections of tunnel groups, the existing anti-skid and deceleration markings usually adopt the same anti-skid and deceleration markings as normal roads. In actual use, there are some defects and deficiencies in varying degrees.

Embodiment 1

[0031] like figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the present invention includes a continuous longitudinal anti-skid marking line 2 respectively arranged at the tunnel entrance 1 and tunnel exit 7 along the driving direction, and a plurality of laterally spaced deceleration marking lines arranged along the driving direction at the outer section of the tunnel entrance hole. 3 and multiple laterally spaced deceleration markings 3 arranged in the road section of the tunnel exit hole along the driving direction. The length of the anti-skid marking line 2 is 30-50m and it extends from outside the hole to the inside of the hole. The distance between the anti-skid marking line 2 and the adjacent deceleration marking line 3 is 4-15m. The length of the road section where the speed reduction line 3 is laid on the road section in the tunnel exit hole is 40-250m.

Embodiment 2

[0036] like Figure 7 As shown, in this embodiment, the difference from Embodiment 1 is that a plurality of deceleration markings 3 distributed at horizontal intervals are also arranged on the road section inside the tunnel entrance hole inside the tunnel entrance 1 along the driving direction, and the tunnel exit 7 There are also multiple deceleration markings 3 distributed at horizontal intervals on the outer section of the tunnel exit, and the length of the section where the deceleration markings 3 are laid on the inner section of the tunnel entrance and the outer section of the tunnel exit is 40-250m . In this embodiment, the length of the road section where deceleration markings 3 are laid on the road section outside the tunnel entrance and the tunnel exit is 200±50m, and the section inside the tunnel entrance and the tunnel exit is laid with deceleration markings. The length of the road section 3 is 40-60m; the distance between the adjacent two groups of deceleration ma...

Abstract

The invention discloses a deceleration and antiskid marked line suitable for an entrance and an exit sections of a tunnel, comprising a section of continuous longitudinal antiskid gage ed line respectively distributed at entrance of the tunnel and the exit of the tunnel along the direction of traffic, a plurality of deceleration marked line transversely distributed at intervals and distributed onthe section outside an entrance hole of the tunnel along the direction of traffic and a plurality of the deceleration marked line transversely distributed at intervals and distributed on the section in an exit hole of the tunnel along the direction of traffic. The antiskid marked line continuously extends to the hole from the outside of the hole and comprises a resin-based adhesive bottom layer directly coated on the road surface, an antiskid skeletal material wearable layer uniformly sprinkled on the resin-based adhesive bottom layer and a colored surface layer coated on the antiskid wearablelayer. The deceleration marked lines are in convex structures. The invention has reasonable design, convenient construction and good use effect, has excellent safety alert and anti-slip effect, and can effectively solve the problem of traffic safety of the entrance and exit sections of the tunnel.

Description

technical field [0001] The invention relates to a safety protection device, in particular to a deceleration and anti-skid marking line suitable for tunnel entrance and exit sections. Background technique [0002] Nowadays, the number of long and extra-long tunnels on domestic expressways is increasing. At the same time, due to the hidden belt-like structure of tunnels, the safety situation is not optimistic. Therefore, in order to ensure the reliability and efficiency of expressway tunnel operation and the safe operation of vehicles at the entrance and exit of the tunnel, it is necessary to combine the specific characteristics of each highway tunnel in practice and take corresponding improvement measures after research. For example, the section from Huxian Jingyang County to Mianxian County of Xihan Expressway is an important section of the national high-speed network Beijing-Kunming line in Shaanxi. The total length is 255.023 kilometers, of which the Qinling No. 1, 2 and ...
