Abstract

A desilting, grouting and reinforcing method for cracks of a pavement with an empty bottom comprises the following steps: injecting water into a void area at the bottom of a rigid pavement slab, stirring to enable sludge to form slurry, thoroughly pumping out the slurry, and then grouting and reinforcing. According to the method, the plate bottom slurry can be thoroughly removed, the void area canbe completely filled with the grouting slurry, a good crack reinforcing effect is achieved, and the problem that the reinforcing material is difficult to inject due to the fact that the bottom of thevoid road rigid pavement plate is silted is fundamentally solved.

Description

technical field [0001] The invention relates to a grouting reinforcement method for pavement cracks, in particular to a dredging and grouting reinforcement method for pavement cracks with empty slab bottoms, and belongs to the technical field of road reinforcement. Background technique [0002] As an important infrastructure for national economic and social development, highways have been rapidly restored and developed after the founding of New China, and China's highway transportation has entered a rapid and healthy development track. In recent years, with the rapid development of my country's economy, the traffic flow has been increasing, and the problem of road damage has become increasingly serious, especially the cement concrete pavement of high-grade roads. [0003] Cement concrete pavement is a pavement structure with high rigidity and strong stability. However, due to the influence of the semi-rigid base, the raw materials and mix ratio of cement concrete have not re...
