Problems solved by technology

Simply increasing the concrete strength label is not conducive to cost control
The prefabricated slab formed by traditional vibration has a lot of laitance on the surface and the strength is reduced; while in the construction of the cast-in-place pavement, the roughening of the road surface in the later stage is also carried out on the low-strength surface, resulting in insufficient durability of the texture after roughening

Abstract

The invention discloses an industrialized prefabrication production line system and method for embossed airport assembled pavement slabs. Rapid and safe machining of the assembled pavement slabs is achieved through mold in-place, reinforcement cage installation, embedded part installation, concrete pouring and vibrating, concrete vacuum water absorption, pressurized surface kneading, surface finishing and embossing, steam curing and pavement slab demolding in sequence. The processed pavement slabs are painted with a surface reinforcing agent and stacked for curing, so that precise processing and curing of the assembled pavement slabs are realized. According to the system and method, redundant water in concrete is effectively discharged, so that the concrete is more compact, the bending strength and the flexural tensile strength of the slabs are improved, and meanwhile, the surface strength reduction caused by vibration is reduced; the compaction degree of concrete on the surfaces of the slabs is better through the pressurized surface kneading procedure, and the durability of the concrete is improved; the embossing process is adopted for manufacturing the surface texture of the prefabricated slabs, so that the texture depth and density can be met, and the texture strength is also improved; and the durability of the concrete is effectively improved by brushing the surface reinforcing agent.

Description

technical field [0001] The invention relates to the field of prefabricated construction, in particular to a factory prefabricated production line system and method for an embossed airport assembly road panel. Background technique [0002] In the airport prefabricated concrete pavement system, the precision and strength of the prefabricated slabs need to be controlled emphatically. The precision of the plate can be controlled by high-precision shaped steel formwork, and how to improve the strength and durability of the plate is further solved. Simply increasing the concrete strength label is not conducive to cost control. The prefabricated slabs formed by traditional vibration have more laitance on the surface and lower strength; while in the construction of cast-in-place pavement, the roughening of the road surface in the later stage is also carried out on the low-strength surface, resulting in insufficient durability of the texture after roughening.
