Background

The precast concrete slabs are manufactured in factories and transported to construction sites to form a pavement which is an assembled (combined) concrete pavement. The fabricated concrete plate is generally made into a square or rectangle with the side length of 1-2 meters, and also can be made into a hexagon with the side length of 1.2 meters, and the plate thickness is 12-18 centimeters; the large-scale plate with the width of 3.5 meters and the length of 3-6 meters can be made, and corresponding transportation and hoisting machines are needed to be matched. The edges and corners of the plate can be provided with reinforcing steel bars, and the whole plate surface can also be provided with reinforcing steel bar nets. In order to improve the quality of concrete, the processes of prestress, vacuum water absorption, mechanical vibration, steam curing and the like can be adopted. The assembled concrete pavement slab can be produced all year round, is not influenced by climate and is easy to ensure the quality; and the paving progress is fast, the vehicle can be put through after paving, and the vehicle is easy to disassemble, replace and repair after being damaged. Therefore, the method is more suitable for parking yards and ports and docks, but has more seams and poor integrity, so the method is rarely adopted on highways and urban road trunks.

When laying precast concrete brick among the prior art, need carry out the application of gluing agent to the edge of each concrete brick one by one usually to make the two link together, but this kind of mode, it is comparatively loaded down with trivial details, operate two great, has caused very big influence to the laying efficiency on combined road surface, and simple gluing agent is connected, after one end time, takes place to become flexible easily, leads to the life on road surface not high.
