Precautions for installing guardrail beam

(1) The corrugated guardrail beam should not have obvious torsion, nor should it be welded or lengthened, and the end burrs must be removed. The layout of columns is based on the control points on the highway, and the spacing between columns is adjusted appropriately according to the measurement distance; The installation of columns should be consistent with the design drawings and coordinated with the road alignment. The columns must be firmly buried in the soil, and the burial depth must reach the specified depth in the design and be perpendicular to the ground.

(2) Regardless of the method used to install the anti-collision waveform guardrail beam, the contractor should try to avoid damaging the pipeline facilities buried under the road surface. If damage is caused, the contractor shall be responsible for repairing it, and the repair cost after the damage shall be borne by the contractor.

(3) After the installation of the anti-collision waveform guardrail beam, a smooth linear shape should be formed in both horizontal and vertical directions. It should effectively guide the landscape and driver's line of sight.
