The Highway Guardrail Total Installation Flow

In the high-speed traffic, special fence, guardrail and protection net are always set as the safety facilities. Among them, highway guardrail is one of the products performing best, with good features of high quality, comprehensive function, long service life and other advantages. This article will introduce the specific introduction for the common highway construction guardrail operating flow.

The operating flow mainly contains these steps as follow:

Preparing work,Construction layout,Drill holes,Pile posts(Embed posts),Inspect and correct the posts positions(Replace the unqualified posts),Connect the off-set blocks,Install the beams,Inspect and correct the beams perpendicularity(Replace the unqualified beams),Overall inspect the bolts and nuts and reinforce them,Install the end terminal,Total inspect the installation quality.

If the following situations occur,take non-standard actions.

1.Avoid piling onto the drainage structure or the other structures.If can’t avoid,adopt non-standard boards for transition.After the operation work,the turned-down edge,the distortion and the crack should not occur on the top of the posts.

2.The drilling work must be in strict accordance with the hole pitch and linearity.The hole site must be treated promptly after drilling work, to prevent rain washing and damaging the sub-grade of the highway.

3.Generally,at the bridge slopes, normal operating machines can’t compact the posts firmly into the earth, which will leads to the poor anti-collision intensity.The solution is to adopt the embedding treatment.

4.Although many construction team intended to adjust the linearity by adjusting the shape of spacer blocks, the better way is to control the linearity at the process of post operations, for that the changing of the block will cause undermine the appearance and lower the anti-collision performance.
