Abstract

The invention provides a damaged concrete pavement panel reinforcing structure and method. The structure comprises a concrete pavement panel, the concrete pavement panel is provided with a reinforcing groove, a plurality of pairs of horizontal steel bar embedding holes are formed in the two walls of the reinforcing groove, and horizontal steel bars are fixedly arranged in the horizontal steel bar embedding holes; a steel fiber reinforced concrete blanket is fixedly poured over the concrete pavement panel. The method comprises the steps of 1, conducting surface debristling; 2, making the reinforcing groove and drilling the plurality of pairs of horizontal steel bar embedding holes; 3, embedding the horizontal steel bars; 4, pouring steel fiber reinforced concrete to form the steel fiber reinforced concrete blanket. By combining the horizontal steel bars with steel fiber reinforced concrete, new cement concrete and old cement concrete cooperation work performance is improved, the bearing capacity of the concrete pavement panel reinforcing area is improved, and the service life and maintenance cycle of a road are prolonged.

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 recent years, my country's economic construction has developed rapidly, and the road transportation industry has advanced by leaps and bounds. The cement concrete pavement has the advantages of high rigidity, high strength, durable use, and small daily maintenance workload. Therefore, some urban roads, industrial and mining roads, and airport runways have been built in large quantities. Concrete pavement, and some high-grade highways have also been built with cement concrete pavement. In my country's highways, ur...
