Rapid construction method for reinforced intelligent crash barriers for highways

Abstract

Te invention discloses a rapid construction method for reinforced intelligent crash barriers for highways. The rapid construction method comprises the following steps including the step 1, setting a concrete structure of each of crash barriers, then, setting formworks, and prefabricating the crash barriers; the step 2, installing each formwork, and forming a plurality of through holes in the sideedge of each formwork, thereby forming a corresponding box of which the top end is unenclosed and which is of a hollow structure; the step 3, filling the sunk positions of each of multiple pieces of corrugated sheet steel with rubber pads, installing a support to the bottom part of each piece of corrugated sheet steel, and putting stainless steel tubes in each box in a penetrating manner, whereinthe projecting face of each piece of corrugated sheet steel faces towards a corresponding main formwork at the front end; and the step 4, pouring concrete into each box, removing the corresponding formwork after pouring is finished to obtain a prefabricated crash barrier, conveying the prefabricated crash barriers to a construction installation site and installing the prefabricated crash barriers,butting adjacent stainless steel tubes, and installing a collision alarm induction module to the rear ends of the crash barriers arranged at a certain distance from each other to obtain the intelligent crash barriers. The rapid construction method effectively increases construction speed, and meanwhile, enhances the crashworthiness and the energy absorption action of each crash barrier.

Description

technical field [0001] The invention relates to the field of guardrail construction, in particular to a rapid construction method for a reinforced road intelligent anti-collision guardrail. Background technique [0002] In the field of construction technology of highway anti-collision barriers, conventional construction methods generally locate the points set up on the side of the highway first, and control the spacing and alignment of steel bars through the pull-wire control method, but the process is cumbersome, and the pull-wire control method is still easy. Affected by the wind, the positioning is inaccurate and the entire construction period is delayed. In the later stage, the formwork is set according to the different road sections, and the concrete is poured. The fixed installation of the formwork is very troublesome, which greatly prolongs the construction period. Contents of the invention [0003] It is an object of the present invention to solve at least the abo...
