I-shaped piling wall type cement pavement crack repairing structure and repairing method

Abstract

The invention discloses an I-shaped piling wall type cement pavement crack repairing structure and a repairing method. The structure comprises an I-shaped piling wall which is arranged along the length extension direction of a crack and is used for continuously repairing a to-be-repaired layer of a pavement, wherein the I-shaped piling wall comprises a web piling wall continuously penetrating through the to-be-repaired layer of the pavement, a lower flange clamping plate located at the bottom of the web piling wall and integrally connected with the web piling wall, and an upper flange clampingplate located at the fixed part of the web piling wall and integrally connected with the web piling wall; the web piling wall intersects with the crack; and the lower flange clamping plate is locatedat the bottom of the crack. The method comprises the steps that 1, drilling of a piling wall hole; and 2, filling of a pouring body. The structure of the invention is simple, the continuous I-shapedpiling wall is used for continuously and comprehensively repairing the whole crack on a cement pavement slab; and the web plate piling wall in the I-shaped piling wall compacts cracks, the upper flange clamping plate and the lower flange clamping plate in the I-shaped piling wall clamp and reinforce the to-be-repaired layer of the pavement, the fractured to-be-repaired layer of the pavement is effectively connected and borne, strength is high, damage to the existing pavement slab is reduced, and a construction period is short.

Description

technical field [0001] The invention belongs to the technical field of repairing cracks on cement pavement, and in particular relates to a structure and method for repairing cracks on an I-shaped pile wall type cement pavement. Background technique [0002] Cement concrete pavement refers to the pavement with cement concrete as the main material, referred to as concrete pavement. Also known as rigid pavement, commonly known as white pavement, it is a high-grade pavement. The concrete upper layer is composed of concrete panels of a certain thickness, which has the property of thermal expansion and contraction. Due to the change of temperature throughout the year, the concrete slab will expand and shrink to different degrees, and there will be different degrees of transverse cracks, fractures, subsidence, surface peeling, wrapping and other diseases. Existing repairs to the defects of concrete pavement are mostly A large amount of crushing of the old road surface, vibration ...

AI Technical Summary

Problems solved by technology

Due to the change of temperature throughout the year, the concrete slab will expand and shrink to different degrees, and there will be different degrees of transverse cracks, fractures, subsidence, surface peeling, wrapping and other diseases. Existing repairs to the defects of concrete pavement are mostly A large amount of crushing of the old road surface, vibration of the subgrade, and re-laying of the base and surface course is required, which is a heavy workload, and the traffic is difficult to maintain during the construction period, and the renovation effect is not satisfactory
