Abstract

The invention discloses a flood-damage-resistant flared wing wall of a culvert. The flared wing wall comprises a wall body, wall body main reinforcements and wall body stirrups, wherein the longitudinal section of the wall body is in a right trapezoid shape, and the top surface of the wall body tilts down from back to front; upper and lower rows of wall body main reinforcements are arranged in the wall body, the plane where the lower row of wall body main reinforcements are located is parallel with the horizontal plane, and the plane where the upper row of wall body main reinforcements are located is parallel with the top surface of the wall body; the multiple wall body stirrups are arranged in the wall body in parallel in a front-and-back manner; each wall body stirrup is in a right trapezoid shape, the lower row of wall body main reinforcements are fixedly connected with the bottom edge of each wall body stirrup, and the upper row of wall body main reinforcements are fixedly connected with the top edge of each wall body stirrup. The wall body main reinforcements are connected together through the wall body stirrups, so that the overall stability of the flared wing wall can be enhanced, the flood scouring resistance of the flared wing wall of the culvert is improved, and collapse of the whole wing wall due to the fact that the local wall body of the culvert is damaged by flood can be avoided.

Description

technical field [0001] The invention relates to the field of highway culverts, in particular to a splayed wing wall of an anti-water damage culvert. Background technique [0002] Culverts are mainly used to accommodate and diffuse water flow. The splayed wing wall is the most commonly used type of culvert opening. The traditional splayed wing wall of a culvert is constructed of mortar rubble. Its structure is simple, the amount of work is small, the cost is low, and the construction is simple. However, the traditional splayed wing wall has poor water damage resistance. When the flood comes, the flood will easily generate vortex erosion at the end of the splayed wing wall, causing the bottom of the wall to be hollowed out and the filler behind the wall to be taken away, which may eventually cause a splayed The wing wall collapsed and damaged, and the roadbed was washed away, causing traffic to be interrupted. In view of this, it is still necessary to improve the splayed win...
