Description

Mortar-free modularized prefabricated pavement structure and construction method thereof Technical Field The invention relates to the technical field of prefabricated pavement structures, in particular to a mortar-free modularized prefabricated pavement structure and a construction method thereof. Background Conventional prefabricated manway pavement is divided into bricks, stones and wood (simulated wood). The brick material and stone material structure comprises cushion layer, base layer, bonding layer and surface layer, wherein the bonding layer is made of cement mortar, and the surface layer and the base layer are bonded together after hardening. These two types of constructions have several problems: Firstly, dust pollution is caused when cement mortar is mixed; secondly, errors are easy to occur in manual joint paving, thirdly, most of the materials are difficult to recycle because the surface layer and the bonding layer are destroyed when the materials are required to be removed.
