Title:
RAPID INTEGRAL SLAB REPLACEMENT CONSTRUCTION PROCESS FOR DAMAGED PAVEMENT SLAB IN CIVIL AVIATION NON-STOP AVIATION CONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2022/151677
Kind Code:
A1
Abstract:
A rapid integral slab replacement construction process for a damaged pavement slab in civil aviation non-stop aviation construction. The rapid integral slab replacement construction process comprises the following steps: stage 1, reinforcing a damaged pavement slab foundation by means of grouting construction; and stage 2: carrying out integral slab replacement construction on the damaged pavement slab by utilizing early-strength quick-drying concrete. Stage 1 involves reinforcing the damaged pavement slab foundation, so as to solve the problems of a slab bottom void, foundation settlement, and the capacity for bearing a base layer being insufficient; and stage 2 involves carrying out integral slab replacement construction on the damaged pavement slab, so as to effectively solve a contradiction between the construction period and the construction quality. The rapid integral slab replacement construction process has the advantages of a significantly shortened construction period, improved construction quality, reduced apparatuses and labor input, etc.
