Precast pavement structure and Z-shaped rubber insert applied to structure

Abstract

The invention provides a precast pavement structure and a Z-shaped rubber insert applied to the structure. The pavement structure is formed by a plurality of T-shaped precast block pavement spliced and clamped together, and the Z-shaped rubber insert is arranged between the splicing faces of the adjacent T-shaped precast blocks in a clamping way. The rubber insert comprises an insert framework and rubber at the outer layer of the insert framework, the insert framework is provided with transverse reinforcing steel wires along two vertical bending directions starting from the corner center, and the framework is provided with a plurality of longitudinal reinforcing steel wires in the longitudinal direction. Under the action of the insert, the tiny rotational deformation of the T-shaped precast blocks under the action of wheels can be achieved so as to reduce the rotational displacement, so that the smoothness in the traveling of construction vehicles is improved, meanwhile, the stress-focusing effect at the internal corners of the precast blocks in the traveling process is weakened, and the integrity and the continuousness of the interlock effect of the pavement structure are achieved.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a prefabricated road surface structure and a design method for a Z-shaped rubber insert used in the structure. Background technique [0002] At present, the construction of pavement structures on the construction site of construction projects can be realized by prefabricated concrete blocks or concrete poured on site. The latter has a long working cycle, cannot be reused, and wastes energy, water and sand and gravel materials. The prefabricated blocks can be carried by manual and mechanical transportation to realize construction anytime and anywhere, which can save time, speed up the construction, save the construction period and equipment investment, and the concrete prefabricated blocks can be reused, improve the turnover rate, and be easy to dismantle, economically. Get good results. [0003] The rubber inserts can be flexibly isolated between the prefabricated blocks on the ...
