Product name waveform guardrail Also known as W-shaped guardrail, high-speed anti-collision guardrail, W-zinc steel guardrail, galvanized guardrail, corrugated guardrail belongs to cold-rolled, Qingyang Expressway guardrail anti-collision guardrail corrugated guardrail board manufacturer
Semi rigid guardrail. surface treatment . Hot galvanizing, cold galvanizing and plastic spraying According to the anti-collision level, it can be divided into Level A and Level S. Class S guardrail is a reinforced type, which is suitable for use in particularly dangerous sections on both sides of the road. Class A guardrail is used for special roads. The main form is a continuous structure with corrugated steel guardrails spliced together and supported by columns. Scope of application. National first-class highways, expressways, sections with special roadside hazards that need to be strengthened protection (such as Panshan Road), and sections with important structures in the midpoint belt that need to be strengthened protection. As important traffic passages, the guardrails of expressways are vital to traffic safety
. Material specification: length X width X wave height X thickness
Double wave wave guardrail board: 4320 * 310 * 85 * 3/4;
Three wave wave guardrail board: 4320 * 506 * 85 * 4;
Double wave column: diameter 114/140 mm × 4.5 mm × height;
Three wave column: diameter 130 130 mm × 6mm × height;
Generally, the column spacing is divided into 2m spacing and 4m spacing;
There are two ways to connect the column with the plate: block type and bracket type.
Standard dosage
Standard amount of corrugated guardrail: the distance between posts in the standard section is 4m, 250 guardrail boards, 250 posts and 2 ends are used per kilometer, Column cap 250, 250 anti blocking blocks, connected Bolt 250 sets of (M16 × 170/42) and 2000 sets of splice bolts (M16 × 35).
Construction scheme of corrugated guardrail
Construction of corrugated guardrail
Corrugated beam steel guardrail is to prevent runaway vehicles from crossing the midpoint separator or rushing out of the subgrade at dangerous roadside sections, so as to avoid secondary accidents; In order to absorb energy, reduce accident and vehicle and personnel damage, guide vision and beautify the road.
construction plan
Materials shall be purchased in strict accordance with the requirements of the bidding documents, and all steels must have material quality certificates according to the requirements of the bidding documents. All steel members of corrugated beam steel guardrail shall be hot-dip galvanized for metal anti-corrosion treatment. After hot-dip galvanized treatment of height bolts, the connecting surface of height bolts shall be coated with grease, and phosphating lubrication treatment shall be carried out. When leaving the factory, they shall be sealed and packaged to prevent rust or dirt during transportation and storage.
