Improved prestressed cable movable guardrail structure

Abstract

The invention discloses an improved prestressed cable movable guardrail structure. The structure comprises a middle frame, a middle connecting component, an end anchoring frame, an end connecting rodand a front opening component, the middle frame is a truss formed by welding or bolted connection of steel pipe cross beams through anti-tripping components; steel wire ropes are arranged in the steelpipe cross beam; the steel wire ropes are fixed at two ends of the steel pipe cross beam; the middle connecting component is connected with the ends of the steel pipe and the steel wire ropes, the bottom of the end anchoring frame is fixedly connected to the ground, guide pipes are arranged on the two sides of the end anchoring frame, the end connecting rod penetrates through the guide pipes, oneend of the end connecting rod is connected with the middle frame through the front opening component, and the other end of the end connecting rod is fixed to the connecting end of the middle frame.

Description

technical field [0001] The invention relates to the technical field of high-speed protection, in particular to an improved prestressed cable movable guardrail structure. Background technique [0002] The movable guardrail is set at the opening of the central divider of the expressway, in order to facilitate the passage of special vehicles such as traffic accident handling vehicles and emergency vehicles in emergency situations and temporarily open and release when the road construction on one side is closed. This road section is prone to vehicles crossing the guardrail with openings in the middle section and colliding with opposing vehicles, causing vicious secondary accidents. [0003] The existing steel pipe prestressed cable movable guardrail can effectively intercept out-of-control vehicles, but at the same time there are some shortcomings: 1. The existing butterfly plate transverse connection components are expensive to manufacture and cause a lot of waste of materials;...

This road section is prone to vehicles crossing the guardrail with openings in the middle divider and colliding with opposing vehicles, causing vicious secondary accidents

[0003] The existing steel pipe prestressed cable movable guardrail can effectively intercept out-of-control vehicles, but at the same time there are some shortcomings: 1. The existing butterfly plate transverse connection components are expensive to manufacture and cause a lot of waste of materials; the existing Japanese-shaped The uprights on both sides of the horizontal connecting member are prone to tripping, which poses a safety risk

2. The existing longitudinal connection method of inner and outer casings is expensive, difficult to install, and not suitable for curved road sections

4. The existing end frame column adopts piling type, which is not easy to replace and maintain

5. The existing end frame structure is not adaptable in length, and there are many large errors in the opening length of the middle belt, which makes installation difficult
