Abstract

The invention belongs to the technical field of highway facilities and particularly relates to a construction method for a Dacromet steel highway handrail. The construction method for the Dacromet steel highway handrail includes the following steps of firstly, construction preparation, secondly, anticorrosive treatment of corrugated plates and uprights, thirdly, measuring, positioning and sampling, fourthly, foundation excavation and pouring, fifthly, upright installation, sixthly, installation of anti-stop blocks, brackets and the corrugated plates, seventhly, end socket installation and eighthly, acceptance check. The construction method is designed reasonably according to the features of the Dacromet steel highway handrail, and the safety performance of the Dacromet steel highway handrail is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of road facilities, and in particular relates to a construction method of Dacromet steel road guardrails. Background technique [0002] Highway guardrails are of great significance to prevent traffic accidents, especially special and major vicious traffic accidents. The commonly used corrugated beam guardrail is the main form of semi-rigid guardrail and an important part of highway traffic safety facilities. This guardrail is made of corrugated steel guardrail panels spliced ​​with each other and supported by columns to form a continuous structure, which can take advantage of the overall deformation of the structure. Absorb the collision energy of the vehicle and force the out-of-control vehicle to change direction to prevent it from rushing out of the guardrail, thereby reducing accident losses. Its function is to prevent high-speed vehicles from rushing out of the road or crossing the central divider into...
