Problems solved by technology

[0003] However, the existing urban greenways combined with the sponge city concept mostly use colored permeable asphalt or permeable sand base as the pavement surface material, which is prone to the following three problems: 1. Due to the influence of outdoor sunlight and rain, the colored surface The color of the decoration material is easy to change; 2. With the opening of the greenway, the rainwater will gradually block the gaps with sediment, which will easily cause the overall water permeability of the permeable pavement structure to decrease, or even fail

Embodiment 1

[0028] see Figure 1-2 , the present invention provides a kind of permeable pavement structure with colored ceramic particles on the edge of the rail, which is characterized in that it includes a surface layer of ceramic permeable particles and a steel rail, and a layer of fine stone permeable concrete is arranged under the surface layer of ceramic permeable particles, and the fine stone permeable concrete A coarse-grained permeable concrete layer is set under the layer, and a graded gravel base is set under the coarse-grained permeable concrete layer. Concrete bases are respectively set on both sides of the mixed gravel base along the road. The granular surface layer, the fine stone permeable concrete layer and the coarse-grained permeable concrete layer are all located between the two side rails, and the bottom of the graded crushed stone base is equipped with a waterproof geotextile, and the waterproof geotextile is laid on the surface of the soil foundation, and the graded ...

Embodiment 2

[0034] see now image 3 A method for constructing a water-permeable pavement made of colored ceramic particles at the edge of a rail, comprising the following steps:

[0035] Step S1, within the scope of the greenway, after cleaning the surface, shape the soil foundation and compact the soil foundation;

[0036] Step S2, subgrade construction, laying waterproof geotextile on the surface of the soil foundation, and laying a seepage pipe covered with seepage geotextile in the center of the greenway on it. into the well, and then lay 10cm thick graded gravel. The graded gravel is rolled firmly by a 12-15t steel wheel roller. After the maintenance, the second layer of 10cm thick graded gravel is paved. Concrete bases are poured on both sides. After the maintenance, the upper layer of 15cm thick coarse-grained permeable concrete layer with a strength of C30 is paved, and the side rails are installed and fixed simultaneously. After the maintenance is completed, the upper layer of 5...

Abstract

The invention belongs to the field of sponge city water-permeable greenway or park footpath construction, and provides a rail edge-closing colored ceramic particle water-permeable pavement structure and a construction method.The rail edge-closing colored ceramic particle water-permeable pavement structure comprises a ceramic water-permeable particle surface layer and an edge-closing steel rail, and a fine stone water-permeable concrete layer is arranged below the ceramic water-permeable particle surface layer; a construction method of the permeable pavement structure with the colored ceramic particles for the edge closing of the rail comprises the following steps that S1, in the greenway range, a soil foundation is modeled and compacted after surface cleaning, and the surface of the soil foundation is cleaned; the method has the beneficial effects that the fired full-body-color ceramic particle material is adopted as the surface layer, the greenway color change condition caused by outdoor conditions is effectively avoided, meanwhile, the fineness of the adopted material is gradually increased from top to bottom, the problem that the water permeability is reduced due to the fact that structural holes are blocked by silt particles can be prevented, and the seepage and drainage pipe is arranged on the base; and permeable water in the greenway can be effectively drained.

Description

technical field [0001] The invention belongs to the field of construction of permeable greenways or park trails in sponge cities, and in particular relates to a permeable pavement structure and a construction method of colored ceramic particles with rail edges. Background technique [0002] At present, more and more cities pay attention to the construction of greenway network. The construction of green infrastructure based on greenway is an important link in urban planning and development. The construction of greenway network can integrate ecology, landscape and recreational functions. Greatly improve the monotonous living environment in the city; at the same time, in the process of high-speed urbanization, my country's railway network is becoming more and more perfect, and railway transportation is extending in all directions. It is worth noting that the number of new railways continues to increase, and the number of abandoned railways It is increasing; the transformation of ...
