3. Guardrail post pile driving

Before桩驱， it's crucial to determine the soil quality at the桩位 to ensure it's suitable for pouring, otherwise it may affect the protective effect of the guardrail panels. Additionally, check if the桩位 is parallel to the subgrade.

4. Bracket and anti-friction block installation

Once the posts are securely installed, you can proceed to mount the brackets and shock blocks. Be sure to check that the shock blocks, brackets, and posts match, as mismatched models cannot be installed. The posts for three-wave guardrails and two-wave guardrails, as well as the guardrails, shock blocks, and brackets, all have different models.

5. Guardrail assembly

Afterward, we can install the guardrail panels, ensuring a seamless joint for the panels. It is strictly prohibited to drag the guardrail panels as they have a plastic coating or galvanized layer on the surface, which can be damaged during dragging, resulting in the loss of the anti-corrosion effect.

Expandable Information:

1) Highway wavy guardrails are the primary form of semi-rigid guardrails. They consist of a continuous structure made up of wavy steel guardrail panels connected by main posts. They absorb collision energy through the deformation of the foundation, posts, and beams, forcing out-of-control vehicles to change direction and resume normal travel, thereby preventing vehicles from running off the road and protecting both vehicles and passengers, reducing losses caused by accidents. Mainly used for fencing, decoration, and protective facilities in industries such as industry, agriculture, city construction, and transportation. Wavy guardrails are hailed as heroes of protective engineering, with highway wavy guardrails playing a crucial role in modern life.

Standard roads and county and rural roads typically use Grade B. Grade B does not require as high standards as Grade A. Grade B can be said to have continued the industry standards from 1995, using 3.0 guardrails, guardrail prices, 114*4.5 posts, highway guardrails, highway guardrail prices, posts for桩driving are usually 1800-2000mm in height, and concrete embedment is typically 800-1000mm. Connected with brackets, bolts are 45 steel, AB anti-theft, post cap thickness 3.0, washer 4.0.

Above units are in millimeters. The corrosion-resistant galvanized layer must reach 600g/㎡. The 4.0 thickness guardrail panels are produced using 4.15 steel strips, and the 3.0 thickness guardrail panels are produced using 3.15 steel strips. This is due to both the inherent tolerance of the steel itself and the loss in thickness during the pickling process.
