Embodiment 1

[0030] Embodiment 1: Laying of ground rainwater collection system:

[0031] Select a 10m*1m ground and lay it according to the following steps

[0032] 1) Tamp and level the ground;

[0033] 2) Lay 15cm stones on the ground and tamp and level them to form the gravel base 4, as shown in Figure 1,

[0034] 3) Use hydrogenated bisphenol A type epoxy resin and quartz sand with a particle size of 1 mm in a ratio of 1:10 and lay it on the gravel base 4, as shown in Figure 2, there are 5 strips with a certain slope on it. The air-permeable layer of the water collecting groove 6; and make the ridge platform 8 between the water collecting grooves be pointed, so that the rainwater can be collected into the water collecting groove 6; the waterproof layer forms a rainwater collecting groove at the bottom of the slope 7;

[0035] 4) Coat the surface of the air-permeable layer described in step 3) with a layer of air-permeable waterproof agent 5 (known water-repellent agent) to form an a...

Embodiment 2

[0041] Embodiment 2: the pavement method of roof rainwater collection system:

[0042] 1) use hydroxyl-containing acrylic resin and 1mm quartz sand in a ratio of 1:8 and lay it on the roof. As shown in Figure 4, a collection groove 7 is formed at the diagonal of the roof. The groove 7 divides the roof into two parts; these two parts of the roof are slopes inclined towards the collecting groove 7 and the water collecting place 8, so that the rainwater is collected into the collecting groove 7; a certain slope;

[0043] 2) Lay a layer of permeable base 2 on the waterproof layer 1 and level it; the material selection of permeable base 2:

[0044] Take 100 parts of quartz sand with a particle size of 0.9 mm, 1 part of diatomaceous earth, and 10 parts of adhesive; the adhesive is hydrogenated bisphenol A epoxy resin and hydrogenated bisphenol A epoxy resin with hydrophilic groups The resins are mixed in a ratio of 10:1.

[0045] 3) Laying permeable bricks 3 on the permeable base...

Abstract

The process of laying rain water collecting system on ground or roof includes the following steps: spreading one waterproof layer in certain thickness on the roof or tamped ground and making the waterproof layer possess certain slope or setting some water guiding grooves in certain slope for guiding rain water to some catchment; and spreading water permeating surface layer on the waterproof layer, or one water permeating base layer and water permeating prefabricated parts. Recovering rain water with the said system can save water source and improve human living environment.

Description

Technical field: [0001] The invention relates to a ground or roof laying method, in particular to a ground or roof rainwater collection system laying method. Background technique: [0002] In today's cities, the ground or roof is mostly paved with cement or asphalt, and the roof or ground is generally impermeable and airtight, and does not have the function of rainwater collection; [0003] The known method of roof rainwater collection is to set a downspout, and the downspout leads water into the container from the sloping roof; [0004] The rainwater collected in this way contains a large amount of impurities and pollutants, which requires secondary filtration before it can be used; [0005] The existing ground generally does not have the function of rainwater collection, and the collection of rainwater can only be done through a separate rainwater collection device; [0006] At present, my country is still a water-deficient country, and there are many cities that lack wa...
