Problems solved by technology

The strength and compactness of permeable concrete are two technical properties that restrict each other. In the existing concrete materials, if the concrete pavement is too dense, the strength can meet the requirements, but the water permeability is not good; if the concrete pavement is dense If the value is too small, the water permeability can meet the requirements, but it is difficult to meet the strength requirements.

Embodiment 1

[0042] Embodiment 1 Referring to Figures 1-5, this rainwater collection permeable concrete pavement system, the pavement 2 is adjacent to the green belt 7 on the side, and there are curbs 3 on the edge of the pavement. The pavement structure consists of a compacted soil layer 9 greater than 10 mm, an ordinary concrete base layer 80-100 mm thick, a permeable concrete structure layer 11 with a thickness of 100-150 mm, and a permeable concrete surface layer 10 with a thickness of 40-60 mm from bottom to top. Composite, the upper surface of the ordinary concrete base has a slope of 1 / 100 to 2 / 100 from one side of the road surface to the other side, and a water collection tank 17 is buried along the length of the road on the side of the road surface, and the water collection tank is provided with a top plate 18. The bottom of the tank is lower than the slope bottom of the ordinary concrete base, and the sump is connected with the rainwater collection tank 1 buried under the green be...

Embodiment 2

[0061] Embodiment 2, when the road surface is wide, the upper surface of the above-mentioned ordinary concrete base has a slope of 1 / 100-2 / 100 from the center of the road surface to the side of the roadside, and both sides of the roadside are equipped with water collection tanks, and the rainwater is diverted to In the collection pipeline network on both sides of the road.

Abstract

The present invention relates to a rainwater-collecting permeable concrete pavement system. It is characterized by that said pavement structure includes rammed earth layer whose thickness is greater than 10mm, general concrete base layer whose thickness is 80-100 mm, permeable concrete structure layer whose thickness is 100-150 mm and permeable concrete face layer whose thickness is 40-60mm from bottom to top. Said pavement system is adjacent to green belt, under the green belt a rainwater-collecting pool is set, and the bottom portion of said rainwater-collecting pool is equipped with a submersible pump. Along the length direction of said pavement structure two sides of said pavement system are respectively equipped with a rainwater-collecting channel, the outlet of said submersible pump is connected with pipe network, and said pipe network is distributed in the green belt.

Description

(1).Technical field [0001] The invention relates to a rainwater collection system, in particular to a rainwater collection system for concrete pavement. (2). Background technology [0002] Due to global climate change and rapid economic and social development, excessive exploitation of groundwater and environmental pollution have caused great damage to available water sources. The water situation is particularly serious and is becoming a bottleneck restricting economic development and social progress. The utilization of rainwater is a systematic technology that benefits the country and the people and is urgently needed. Among them, although permeable concrete pavement has been studied in our country, so far there has been no report on the large-scale application of load-bearing pavement and the combination of rainwater recycling and utilization projects. Analyzing its reason, mainly contain following three technical problems: [0003] 1), material constraints. It is a te...
