Road concrete fence anti-collision reinforcing method

Abstract

The invention discloses a highway concrete fence anti-collision reinforcing method which comprises the following steps of: 1, analyzing the limited vehicle speed of a fence section, previous overspeed records, accident records and road gradient and bending conditions, and setting reinforcing thickness according to road violation conditions and accident conditions; 2, carrying out survey lofting; 3, binding and welding reinforcing steel bars by taking a marking curve as a reference; 4, installing an anti-collision steel plate structure 5; 5, injecting concrete; and 6, welding a reinforcing cover. According to the method, the road violation conditions and accident conditions of road sections are analyzed, so that the reinforcement thickness is calculated, and the reinforcement requirements of different road section conditions are met.

Description

technical field [0001] The invention relates to the technical field of concrete fence reinforcement methods, in particular to an anti-collision reinforcement method for highway concrete fences. Background technique [0002] Highways are roads that connect cities, villages, and industrial and mining bases. In order to facilitate construction, concrete fences are required in the process of road construction. Concrete fences are mostly mixed with concrete, and then formed inside the mold. In this process, in order to avoid air bubbles in the concrete fence affecting the quality of the fence, it is necessary to set up a concrete vibrator to increase the discharge rate of the air bubbles during pouring. The concrete fence will be damaged in different ways after long-term use and collision. Sometimes it is necessary to strengthen the concrete fence through the anti-collision reinforcement method of the concrete fence, so as to prolong its service life. [0003] At present, most o...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the anti-collision reinforcement methods for concrete fences on the market are reinforced by increasing the cross-section and pasting fibers to increase the load material. Although the bearing capacity and stiffness of the components have been improved, the requirements for reinforcement are different for curves or accident-prone road sections and straight road sections. It is difficult to meet the reinforcement requirements of curves or accident-prone road sections, and the reinforcement of straight road sections is too thick to reduce the width of emergency lanes, resulting in unreasonable reinforcement distribution.
