Problems solved by technology

Although the above-mentioned cement pavement structure can solve the problem of rapid pavement pavement, it is difficult to improve the integrity of the structure after assembly, and it cannot overcome the problems of thermal shrinkage and deformation of concrete slabs and connection with the lower structural layer
[0004] To sum up, although the existing concrete pavement structure and construction methods have achieved good results under suitable working conditions, there are still areas that can be further improved in terms of road surface performance improvement, construction efficiency improvement, and overall improvement. place

Abstract

The invention provides a combined assembled cement concrete pavement structure and a construction method, wherein a water barrier layer, a drainage strip and a drainage base layer are laid on the subbase layer, and the drainage strip is connected with the vertical drainage pipe in the prefabricated panel section; A joint end plate, a joint end plate 2 and a squeeze filler body are arranged at thevertical joint of the prefabricated plate section and the cast-in-place joint section, and a limit joint and a flexible joint layer are arranged at the joint of the lower surface, and the upper surface is provided. The deformation coordination plate is disposed, and the tension connecting rib is disposed in the middle; the tension connecting rib of the prefabricated plate segment and the cast-in-place connecting segment is provided with a limiting clip through the two ends of the hole, and the tension connecting rib is connected by the locking bolt; The upper surface of the lower connecting platform of the cast-in-place connecting section is provided with a connecting limit groove, and the bottom is integrally formed with the vertical reinforcing pier. The pavement structure and the construction method provided by the invention can not only improve on-site construction efficiency and construction quality, but also enhance the integrity of the pavement structure and improve the temperature stability and durability of the pavement structure.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a combined assembled cement concrete pavement structure and a construction method. Background technique [0002] Concrete pavement is widely used in the construction of urban roads and highways in my country. Compared with asphalt pavement structure, the construction period and water damage resistance of concrete pavement are often its shortcomings. In this regard, engineering and academia have carried out some useful research. Targeted research, put forward some improvement measures. [0003] At present, there is a prefabricated assembled concrete pavement; a prefabricated assembled concrete pavement, including a prefabricated concrete pavement, the four corners of the prefabricated concrete pavement are provided with bolt holes that match the prefabricated bolts embedded in the foundation, The surroundings and edges of the main body of the precast concrete road slab are covere...
