Protective pipe for guardrail and guardrail with same
The protective pipe comprises a protective pipe body, the protective pipe body comprises a first side pipe section, a second side pipe section, a third side pipe section and a fourth side pipe section which are sequentially connected end to end, and the first side pipe section and the third side pipe section are oppositely arranged in the width direction of the protective pipe body; wherein the wall thickness of at least part of the section body of at least one of the first side pipe section and the third side pipe section is larger than that of at least one of the second side pipe section and the fourth side pipe section. According to the protective pipe for the guardrail and the guardrail with the protective pipe, the protective pipe is subjected to wall thickness changing design, thick wall setting is carried out on the main stress position in the protective pipe, thin wall setting is carried out on the non-main stress position in the protective pipe, the overall protective strength of the guardrail can reach the needed protective strength, meanwhile, the cost of the protective pipe can be reduced, and the practicability is high. And the protection utilization rate of the protection pipe is further improved.
本申请提供一种护栏用护管及具有其的护栏，包括护管，护管包括首尾顺次连接的第一侧管段、第二侧管段、第三侧管段和第四侧管段，第一侧管段和第三侧管段在沿护管的宽度方向相对设置，其中第一侧管段和第三侧管段中的至少一个的至少部分段体的壁厚大于第二侧管段和第四侧管段中的至少一个的壁厚。本申请提供的护栏用护管及具有其的护栏，通过将护管进行变壁厚设计，实现对护管中主要受力位置进行厚壁设置以及非主要受力位置进行薄壁设置，使得护栏在整体防护强度能够达到所需的防护强度的同时，还能够降低护管的成本，进而提高了护管的防护利用率。
