Common sense of road traffic equipment of guardrail

The high-speed guardrail, also known as the high-speed collision wall, uses the deformation of the soil foundation, pillars and beams to absorb collision energy, and forces out-of-control vehicles to change direction and return to the normal driving direction, prevent vehicles from rushing out of the road, protect vehicles and passengers, and reduce The loss caused by the accident. Highway protection equipment is composed of guardrail, column, anti-blocking block, bracket, waterproof cap and anti-glare board.

High-speed guardrail panels have the advantages of good impact resistance, low cost, long life, high safety, and environmental protection.

Uses: Highway anti-collision facilities, isolation facilities, etc.

Uses: Mainly used for isolation protection wave guardrails of highway lanes. The utility model relates to a composite wave plate movable steel guardrail used at the opening of a highway central partition. The guardrail is composed of two corrugated steel guardrail panels and a fixing clip between the two guardrails. It consists of two uprights, which are sandwiched between two corrugated steel guardrail boards. When the expressway is in normal operation, by using the plug-in column, the guardrail can be easily inserted into the preset insertion hole at the opening to play a role of isolation and protection. At the same time, it echoes the guardrail belt outside the road, neat and even. Corrugated beam guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrail panels spliced with each other and supported by the main column. It uses the deformation of the soil foundation, pillars and beams to absorb collision energy, and forces out-of-control vehicles to change direction and return to the normal driving direction, thereby preventing vehicles from rushing out of the road, protecting vehicles and passengers, and reducing losses caused by accidents. The corrugated beam guardrail is made of steel and flexible, has the ability to absorb collision energy, has a good line of sight guiding function, can be used with road lines, and has a beautiful appearance. It can be used for small radius elbows, and the damaged place is easy to replace. The combined beam guardrail can be used for narrow central partitions. For the part where the vehicle exceeds the road (bridge) and may cause serious consequences, you can choose to strengthen the wave-shaped guardrail.

Precaution:

1. The construction preparation must be adequate, and the pile number of the construction section must be accurately found. The stakeout should be accurate and the error should be within the specified range.

2. Column construction should be strict and serious, and its verticality, spacing, bolt hole position and other dimensions should meet the requirements. If it does not meet the requirements, it needs to be reworked immediately. At the same time, it should be reworked in strict accordance with the specification JTJ074-94.

3. The packaging and marking of corrugated beams, columns and other components shall comply with the regulations of GB6725. When purchasing, do not pack the guardrail in bulk, and ensure that the product will not be deformed or damaged (injured) during hoisting, transportation and stacking. It should be fixed and reliable during transportation to prevent damage to the coating or deformation of components due to bumps and collisions.

4. When purchasing goods, pay attention to the packaging and marking of the corrugated beam high-strength splicing bolt joints should meet the relevant regulations of GB/T1231.

5. The construction of the guardrail should be operated carefully, and do not damage the cables, pipes and other facilities buried under the road.
