Embodiment Construction

[0046] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings, and those skilled in the art will be able to implement them using related technologies in the field as described below.

[0047] like figure 1 and figure 2 As shown, a permeable pavement structure based on construction waste crushed materials, the pavement structure is composed of permeable concrete surface layer, glass fiber grid, recycled concrete upper base, geocell-construction waste ground material lower base, cushion, gravel filter Belt, plastic blind ditch, side drain pipe, curb stone, drainage ditch, waterproof geomembrane. Its paving method consists of the following steps:

[0048] Ⅰ. Excavate, level and compact the original roadbed, install curbstones on both sides of the roadbed, excavate trenches and set drainage ditches;

[0049] Ⅱ. Lay a waterproof geomembrane on the subgrade, and use a hot wedge welding machine to weld the membrane and...

Abstract

The invention discloses a water-permeable pavement structure based on a construction waste smashing material and a laying method of the structure. The pavement structure is arranged above a roadbed and is composed of a water-permeable concrete pavement, glass fiber grids, a recycled concrete upper base layer, an earthwork standard room-construction waste smashing material lower base layer, a gravel filtering band, a plastic blind ditch, a side discharging pipe, kerb, a drainage ditch, a pad layer and a waterproof geomembrane. According to the structure, through the characteristic of high waterabsorptivity of the construction waste smashing material, construction waste is efficiently recycled. The pavement structure has the functions of rainwater permeation, purification and storage for aroad, the positive effects of relieving the urban inland inundation and adjusting the microclimate of an area are achieved, and the structure can be used as a composition part for constructing a sponge city. The water-permeable pavement structure has high strength and also has the functions of water permeation, water storage, water purification and clogging prevention.

Description

technical field [0001] The invention relates to the technical field of road engineering design and construction, in particular to a permeable pavement structure based on crushed construction waste and a paving method thereof. Background technique [0002] Permeable pavement helps to solve problems such as road surface water or poor drainage in rainy days, and it is part of the realization of the concept of sponge city. The roads of the sponge city not only have the function of infiltration but also have the function of water storage, so as to absorb water when it is flooded and release water when it is dry. However, the water storage capacity of existing permeable pavement structures cannot meet the requirements of sponge cities. In addition, for the permeable pavement with organized drainage, the particles in the pores are easy to accumulate near the drainage pipe, which will cause the drainage pipe to block after a period of time, which will cause problems such as poor dr...
