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] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, the present invention includes a section of continuous longitudinal anti-skid markings 2 respectively arranged at the tunnel entrance 1 and tunnel exit 7 along the driving direction, and multi-lane laterally spaced deceleration markings arranged along the driving direction on the section outside the tunnel entrance. 3 and the multi-lane deceleration markings 3 arranged at intervals in the tunnel exit along the driving direction. The length of the anti-slip marking line 2 is 30-50m and it extends from the outside of the cave to the inside of the cave. The distance between the anti-slip marking line 2 and the adjacent deceleration marking line 3 is 4-15m. The length of the road section where the deceleration marking line 3 is laid on the road section at the exit of the tunnel is 40-250m.

Embodiment 2

[0036] Such as Figure 7 As shown, in this embodiment, the difference from Embodiment 1 is that a plurality of deceleration markings 3 distributed laterally at intervals are also arranged on the tunnel entrance section inside the tunnel entrance 1 along the driving direction, and the tunnel exit 7. There are also multiple deceleration markings 3 distributed laterally at intervals on the outer section of the tunnel exit, and the length of the section where the deceleration marking 3 is laid on the section inside the tunnel entrance and the section outside the exit of the tunnel is 40-250m. . In this embodiment, the section length of the deceleration marking 3 laid on the section outside the tunnel entrance and the section outside the tunnel exit is 200 ± 50m, and the section inside the tunnel entrance and the section inside 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...

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 wearable layer. 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-slip marking line suitable for tunnel entrance and exit sections. Background technique [0002] Nowadays, there are more and more long tunnels and extra-long tunnels on domestic expressways. At the same time, the safety situation is not optimistic due to the hidden belt-like structural characteristics of the tunnels. Therefore, in order to ensure the reliability and efficiency of expressway tunnel operation and ensure the safe operation of vehicles at the entrance and exit sections of the tunnel, it is necessary to take corresponding improvement measures after research in combination with the specific characteristics of each highway tunnel in practice. For example, the Huxian County to Mianxian section of the Western Han Expressway is an important section of the National Highway Network Beijing-Kunming Line in Shaanxi. The total length is 255.023 kilometers, ...
