How to install guardrail plate column project

How to install guardrail plate column project

2016-10-19

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!

Waveform guardrail plate construction precautions

Waveform guardrail plate construction precautions

2016-10-14

Waveform guardrail plate construction precautions 1). Construction preparation should be sufficient, construction section pile number location to find accurate. Sampling should be accurate, the error is within the specified range.　　2). Column construction should be strict and careful, its verticality, spacing, bolt hole location and other dimensions should meet the requirements, do not meet the requirements need to rework immediately, at the same time, should be strictly in accordance with the provisions of the specification JTJ074-94 rework.　　3). Waveform beam plate, column and other components of the packaging and marking should be in line with the provisions of GB6725. The guardrail shall not be bulked when purchased, and it should be ensured that the products are not deformed or damaged (injured) during lifting, transport and stacking.
