Collision-proof highway isolation fence

Abstract

The invention discloses a collision-proof highway isolation fence which comprises supporting frames and an isolation box. The supporting frames are arranged in a bilateral symmetrical mode, grooves are formed in the upper end and the lower end of supporting rods, sliding rails are arranged in the grooves, sliding blocks are arranged on the sliding rails, the isolation box is connected with the sliding blocks through connecting rods and comprises a housing, a noise reduction plate is arranged in the internal middle of the housing and is provided with noise reduction holes, noise absorption sponge is arranged on the left side and right side of the noise reduction plate, the noise reduction plate divides the housing into a left noise reduction chamber and a right noise reduction chamber, themiddle of the left noise reduction chamber and the middle of the right noise reduction chamber are provided with partition plates, the partition plates divide the left noise reduction chamber and theright noise reduction chamber into first noise reduction cavities and second noise reduction cavities, a plurality of noise reduction tubes are arranged in the second noise reduction cavities, a plurality of round holes are formed in the partition plates, damping devices are arranged at the front end and the rear end of each sliding block, and the outer ends of the damping devices are connected with the grooves. The collision-proof highway isolation fence is simple in structure, convenient to use, good in collision-proof effect, high in safety and strong in collision-proof performance.

Description

technical field [0001] The invention relates to the technical field of isolation barriers, in particular to an anti-collision highway isolation barrier. Background technique [0002] With the development of society, roads and railways have developed rapidly. Usually all need to arrange a large amount of guardrails to enclose the highway on roadside, railway roadside. Highway sections, mountain roads, etc. need to set up guardrails, that is, to clearly separate the traffic lanes of the highway, and when traffic accidents such as car accidents occur on the road, the guardrails can block part of the impact force, and the number of vehicles that will be affected Minimized, the existing municipal road barriers are generally the most common guardrails, which can only play the role of isolating vehicles, and cannot effectively absorb the noise from cars driving on the road. Moreover, the anti-collision measures on the current isolation fence all adopt structures such as shock abs...

Problems solved by technology

Highway sections, mountain roads, etc. need to set up guardrails, that is, to clearly separate the traffic lanes of the highway, and when traffic accidents such as car accidents occur on the road, the guardrails can block part of the impact force, and the number of vehicles that will be affected Minimize, the existing municipal road barriers are generally the most common guardrails, which can only play the role of isolating vehicles, and cannot effectively absorb the noise from cars driving on the road

Moreover, the current anti-collision measures on the isolation fence all adopt structures such as shock absorbing plates, the buffer distance is short, and it is difficult to play a good buffering effect, making the isolation fence easy to hit and fly
