Expressway protective fence based on waste tires and manufacturing method thereof

Abstract

The invention discloses an expressway protective fence based on waste tires and a manufacturing method thereof. The expressway protective fence comprises a concrete column, a fixing bottom plate, a fixing panel, a first bolt, a second bolt and the waste tires. The fixing bottom plate is contained in a reserved gallery below the ground, the first bolt and the second bolt are fixed to the two ends of the concrete column respectively, an internal thread structure matched with the first bolt is arranged on the fixing bottom plate, an internal thread structure matched with the second bolt is arranged on the fixing panel, the concrete column is sequentially sleeved with the waste tires in the mode that external diameters gradually become smaller, the waste tire on the bottommost layer makes contact with the fixing bottom plate, the waste tire on the uppermost layer makes contact with the fixing panel, and the waste tires are movably connected. The protective fence is manufactured by fully utilizing the waste tires, the protective fence is elastic, tough and high in strength, the functions of buffering and crack-breakage prevention can be completely achieved, and the protective fence is not likely to be crashed out during an automobile collision.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a highway protection barrier based on discarded tires and a manufacturing method thereof. Background technique [0002] Most of the existing highway guardrails are formed by bending metal materials. It is a continuous structure and a buffer that are spliced ​​with corrugated steel guardrails and supported by main pillars. When the vehicle collides with it, because the corrugated steel guardrail has good crashworthiness and energy absorption effect, it can effectively prevent crashes, and at the same time, it can play a certain role in safety protection for drivers and passengers. The products are divided into double waveform (length 4320MM, width 310MM, wave depth 85MM, plate thickness 3-4MM) and triple wave form (length 4320MM, width 506MM, wave depth 85MM, plate thickness 3-4MM). The fly in the ointment is that the current high-speed Highway guardrails are still easy to...

AI Technical Summary

Problems solved by technology

The products are divided into double waveform (length 4320MM, width 310MM, wave depth 85MM, plate thickness 3-4MM) and triple wave form (length 4320MM, width 506MM, wave depth 85MM, plate thickness 3-4MM). The fly in the ointment is that the current high-speed Highway guardrails are still easy to be crashed and broken by cars, especially in the process of collision, sparks will be generated, which will cause serious damage to cars and casualties caused by car burning. Most of the traffic accidents are caused by the collision of highway guardrails. caused by

[0003] Facts have proved that the existing highway safety barriers cannot ensure safety. As we all know, when the ship docks, there are some discarded car tires hanging on the shore. Think about the impact force of tens of thousands of tons of tires. Highway guardrail not only has low manufacturing cost and simple construction, but also can greatly improve protection safety and reduce safety accidents
