Cement pavement crack reinforcing structure and method

Abstract

The invention discloses a cement pavement crack reinforcing structure and a method. The structure comprises a three-dimensional continuous structure reinforcing body for continuously reinforcing cracks in a to-be-repaired layer of a pavement, the three-dimensional continuous structure reinforcing body comprises a plurality of oblique connecting piles which are sequentially connected in the extending direction of the cracks, each oblique connecting pile is connected with a plurality of reinforcing piles, and the intersection ends of the oblique connecting piles and the reinforcing piles are expansion anchoring heads; the method comprises the following steps: 1, drilling an inclined pile hole; 2, drilling a reinforcing pile hole; 3, drilling and chambering; 4, filling and pouring body. According to the invention, the plurality of continuous oblique connecting piles and the plurality of reinforcing piles are intersected to form a three-dimensional continuous structure reinforcing body; anexpanded upper flange clamping plate can be constructed at the tops of the oblique connecting piles and the tops of the reinforcing piles, an expanded anchoring head and the corresponding upper flange clamping plate in the three-dimensional continuous structure reinforcing body clamp and reinforce a pavement to-be-repaired layer, the fractured pavement to-be-repaired layer is effectively connected and borne, the topological structure of the three-dimensional continuous structure reinforcing body is flexibly expanded, and the construction period is short.

Description

technical field [0001] The invention belongs to the technical field of pavement repair, and in particular relates to a cement pavement crack reinforcement structure and method. 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 number of crushing of old road surfaces, vibrating subgrades, and re-laying of base and surface courses i...

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 old road surfaces, vibration of subgrades, and re-laying of base and surface courses is required. The workload is heavy, traffic is difficult to maintain during construction, a large amount of construction waste needs to be piled up, and the renovation effect is not satisfactory. At the same time, the cost is high
