Water permeability pavement structure

Abstract

The invention discloses a water permeability pavement structure which comprises a foundation layer. A pitch wearing layer is arranged on the lower surface of the foundation layer and is bonded to the foundation layer through concrete mortar. A water permeating layer is arranged on the lower surface of the pitch wearing layer and internally provided with more than one water permeating pipe. The tops of the water permeating pipes are arranged to penetrate the pitch wearing layer and the foundation layer and are located on the same horizontal plane with the upper surface of the foundation layer. A slurry sealing layer is arranged on the lower surface of the water permeating layer and is bonded to the water permeating layer through sealing glue. A bottom layer is arranged on the lower surface of the slurry sealing layer and is internally provided with more than one steel ball. The steel balls are evenly arranged on the bottom layer. The water permeability pavement structure is reasonable in structural design, simple in construction technology, smooth in pavement and high in carrying capability; furthermore, the phenomenon of damage and cracks of the pavement is not likely to occur, good permeability is achieved, and the water accumulation phenomenon is effectively avoided when the rainfall is large.

Description

technical field [0001] The invention relates to a pavement structure, in particular to a water-permeable pavement structure. Background technique [0002] The surface of modern cities is constantly covered by reinforced concrete buildings and impermeable roads. Ordinary cement concrete paved roads bring great convenience to people's travel and commodity circulation, although they improve production efficiency and quality of life. , but compared with natural soil, ordinary cement concrete pavement lacks the ability to absorb heat and infiltrate rainwater, which brings a series of problems. At present, in urban road construction, there are various road structures, but most of them have Defects or deficiencies such as rough and uneven road surface, poor bearing capacity, easy early damage to the road surface, cracking of easy-to-break boards, and cumbersome construction techniques. Contents of the invention [0003] The technical problem to be solved by the present invention...
