Reinforcing structure and method for damaged concrete pavement panel

Abstract

The invention provides a reinforcing structure and method for a damaged concrete pavement panel. The reinforcing structure for the damaged concrete pavement panel comprises the concrete pavement panel with the planed surface, a reinforcing groove, multiple pairs of horizontal rebar embedding holes, and vertical rebar embedding holes. The horizontal rib embedding holes are formed in the two groove walls of the reinforcing groove, and the vertical rib embedding holes are formed in the concrete pavement panel. Horizontal rebars are fixedly arranged in the horizontal rebar embedding holes, vertical rebars are fixedly arranged in the vertical rebar embedding holes, and a steel fiber reinforced concrete cover is poured and fixed to the concrete pavement panel. The reinforcing method for the damaged concrete pavement panel includes the following steps that 1, surface planing is conducted; 2, the reinforcing groove is formed, and the multiple pairs of horizontal rebar embedding holes and the multiple pairs of vertical rebar embedding holes are drilled; 3, construction glue is poured, and the horizontal rebars and the vertical rebars are embedded; 4, steel fiber reinforced concrete is poured to form the steel fiber reinforced concrete cover. The bearing capacity of the concrete pavement panel is increased, the service life and the maintenance period of a road are prolonged, and the long-term use cost is reduced.

Description

technical field [0001] The invention relates to repair and reinforcement of damaged concrete pavement panels, in particular to a reinforcement structure of damaged concrete pavement panels and a reinforcement method for damaged concrete pavement panels. 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, it is a high-grade pavement. In my country's highways, urban roads, industrial and mining roads, and airport pavements, the most widely used is the ordinary concrete pavement poured on site. This type of concrete pavement is not configured except for joint areas and local areas (edges or corners). Steel bars, also known as plain concrete pavement. [0003] Ordinary cement concrete pavement structure is easy to construct and low in cost. However, its strength is low. With the increase of vehicle traffic in recent years, the load capacity and dr...

AI Technical Summary

Problems solved by technology

However, the above method cannot fundamentally solve the problem of low tensile strength of ordinary cement concrete pavement (road) and large deformation of new cement concrete, which leads to cracking of the weak bonded surface with the original cement concrete, and cracking damage occurs again in a short period of time after repeated loading And other issues

[0005] Therefore, it is urgent to seek a new repair and reinforcement method to solve the fundamental problems of ordinary cement concrete pavement, such as low strength and easy cracking after traditional repair and reinforcement methods, poor synergy between new and old cement concrete, short service life, and high long-term use costs. question
