Fourth, the installation of the transverse beam and the end:
The connecting bolts between the transverse beam and the column should not be tightened prematurely before the wave beam is installed, and the bolts can only be tightened after the transverse beam and the wave beam are in place accurately. End anchoring mainly includes anchors and concrete foundation, and the bolts can only be tightened after the design strength of the end foundation concrete reaches 50%.
5. Adjustment:
Due to the influence of road alignment, road shoulder, soil quality and many other factors during on-site construction, the dimensions marked in the design and construction drawing should be adjusted according to the turning radius and alignment of the road during construction to ensure the safety performance of the guardrail and the appearance of the alignment Effect.
The existence of high-speed guardrail equipment is to ensure the existence of people's safety. The premise that this kind of high-speed guardrail equipment can work is that the high-speed guardrail equipment must be installed according to the specifications during installation, so that the high-speed guardrail equipment after installation can be Play a protective role in special circumstances. As a manufacturer of high-speed guardrail equipment, it is the responsibility to standardize the installation of high-speed guardrail equipment, and it is also responsible for the personal safety of pedestrians.
