I. Installation of anti-block, waveform beam and end (a) After adjusting the column, the bracket (anti-block) can be installed. The bracket (block) is fixed between the waveform beam and the column through the connecting bolt. Before tightening the connecting bolts, the bracket (block) should be adjusted so that it is accurately seated. (b) Waveform beams are spliced with each other through splicing bolts and fixed on brackets (block) by connecting bolts. The lap direction of the roadbed guardrail and waveform beam is the key to installation, and it is installed strictly according to the drawings. Lap direction should be consistent with the direction of travel. Waveform beams should be continuously adjusted during installation. Therefore, its connecting bolts and splices should not be tightened prematurely.

Corrugated beam guardrail according to the location of the installation is divided into roadside, central divider. Corrugated beam guardrail single-sided is a split-type guardrail for the road side and the central divider is relatively wide and more structures within the divider, and buried in the central divider under the pipeline road is single-sided. Waveform beam guardrail double-sided is a combination of guardrail for the narrow width of the divider, the central divider is not much structure or buried pipeline less road is two sides, combination of waveform guardrail: is composed of columns, cross-separation beams, waveform beams, fasteners, columns can be used in the manufacture of round or channel and other steel. Cross beam consists of two channel steel, respectively installed on both sides of the column.

1, column sampling: 1, (1) according to the design drawings and road base unit provided by the road centre line and elevation data sampling, and bridges, attempts, culverts and other control points for measurement and positioning (2) has been implemented in part of the shoulder wall and the outer retaining wall due to the inconsistency of connecting lines, in order to ensure that the waveform guardrail of the smoothness of the original shoulder wall needs to be added to the outside of the concrete or slurry masonry chip to join the smoothness of the original shoulder wall. (3) Survey the whole line shoulder reserved hole, in principle, in the shoulder construction unit reserved hole position to install guardrail columns. If the location of the original hole does not meet the requirements or not leave a hole, first report to the supervising engineer and re-establish the construction method of the guardrail column. 2, column installation (

Highway guardrail every bit of distance on the signage made of reflective materials, normal straight section 50 m 1, 20 m 1 curve, ramp 5 m / a, with a very obvious warning effect, this signage surface coated with a layer of reflective rate of high fluorescent paint, can be various angles of incidence of light reflection out of the relative concentration of parallel light. In the absence of light conditions will show very dark, once there is light shot to the surface of the signage, it will shoot back in the direction from which it came. Highway in front of the role of reflective panels, road width, corner, slope at a glance!
