Description

The laying method of ground or roof rain water collecting system
Technical field:
The present invention relates to the laying method on a kind of ground or roof, the laying method of particularly a kind of ground or roof rain water collecting system.
Background technology:
In current city, ground or roof are mostly with cement or asphalt paving, and roof or ground are generally waterproof, also airtight, do not have the rainwater collecting function;
The method of known roof rain water collecting is, a leader is set, and described leader is guided in the container from the roof Jiang Shui that tilts;
The rainwater of Shou Jiing contains a large amount of impurity and pollutant like this, needs secondary filter just can utilize;
Existing ground does not generally have the rainwater collecting function, collect rainwater and can only finish by independent rain collector;
China still belongs to lack of water country at present, and the city quantity of lack of water is a lot, and existing rain collector can't large-arealy use, and natural rainwater resource is not well utilized, and has caused the waste of resource; For the better utilization rainwater resource, natural rainwater second use, fully economize on resources and utilize resource, demand a kind of foundation of the rain water collecting system of promoting at roof and ground surface large area urgently.
Summary of the invention
Waterproof, airtight for the secondary filter problem that solves roof rain water collecting of the prior art and ground, can not collect deficiency such as rainwater, but the present invention develops the ground that a kind of large tracts of land promotes or the laying method of roof rain water collecting system.
Technical scheme of the present invention is: the laying method of ground or roof rain water collecting system, and its laying step is as follows:
1) laying certain thickness waterproofing course on the roof or on the ground of compacting, and making described waterproofing course have certain gradient or be furnished with some grooves that catchment on it with catchment that rainwater is directed into appointment of certain slope;
2) on waterproofing course, lay permeable top layer; Or on waterproofing course, lay one deck porous base course, levelling, the permeable prefabricated component of on porous base course, mating formation then.
Above-mentioned waterproofing course is preferably the breathable waterproof layer, and described breathable waterproof layer is laid as follows and formed:
A) be laid to the air-permeable layer that has certain gradient or be furnished with the groove that catchments of some catchments that rainwater directed into appointment with certain slope on it with the mixture of resinae adhesive and aggregate;
B) it is as the agent of the described air-permeable layer surface-coated of step a) one deck breathable waterproof, to form the breathable waterproof layer.
The ground of described step 1) was preferably laid certain thickness stone and was tamped levelling before laying waterproofing course, to strengthen the supporting capacity on ground or roof greatly;
The described ridge platform that catchments between the groove is a convex, so that rainwater is pooled in the rainwater feeder.
Described waterproofing course is formed with rainwater in the bottom on slope and compiles groove, and water is pooled in the concentrated rainwater collection container;
Described porous base course is mixed by water permeability cementing agent and aggregate, and this porous base course is not only permeable but also can closely combine with permeable prefabricated component;
Described water permeability cementing agent is preferably the resinae water-permeable binder; Described resinae water-permeable binder includes one of epoxy resin, polyurethane resin, acrylic resin and conventional hydrophilic additive at least.
Described permeable prefabricated component is generally permeable brick or porous disc etc.
Described permeable prefabricated component preferably by including particle diameter at least is: 0.07 millimeter～1.6 millimeters the natural siliceous sand and the mixture of resinae water-permeable binder mix; Described resinae water-permeable binder and natural siliceous sand mass ratio are: 1～20%.Permeable prefabricated component like this has good water permeability and water filtration function.
The present invention has the following advantages ground or roof owing to implement above technical scheme:
1, the multilayer on the waterproofing course on ground or roof, porous base course, permeable top layer is mated formation, and makes roof or ground have dmp filter and collecting function, realizes the recycling of rainwater, the conserve water resource, and improved existent environment of people.
2, the laying of porous base course has strengthened the adhesion on permeable prefabricated component and ground or roof, has effectively strengthened the supporting capacity on ground or roof;
3, the design of breathable waterproof layer has strengthened the gas permeability on ground, has effectively improved ecological environment.

The specific embodiment:
For inventive concept of the present invention and design scheme better are described, the present invention is further illustrated in conjunction with specific embodiments:
Embodiment 1: the laying of ground rainwater gathering system:
Choose the ground of a 10m*1m, lay as follows
1) levelling is tamped on ground;
2) lay the stone of 15cm and tamp levelling and form crushed rock base course 4 then on the ground, as shown in Figure 1,
3) be to be laid on the crushed rock base course 4 after the quartz sand of 1mm mixes in 1: 10 ratio with bisphenol-A epoxy resin and particle diameter, as shown in Figure 2, be furnished with 5 air-permeable layer thereon with the groove 6 that catchments of certain slope; And make the ridge platform 8 that catchments between the groove for pointed, so that rainwater is pooled to the groove 6 that catchments; Waterproofing course is formed with rainwater in the bottom on slope and compiles groove 7;
4) with the described air-permeable layer surface-coated of step 3) one deck breathable waterproof agent 5 (known waterproof agents) to form breathable waterproof layer 1;
5) on breathable waterproof layer 1, lay one deck porous base course 2, levelling; The material selection of porous base course 2: particle diameter is that quartz sand, crushed crude pearlite, the adhesive of 0.9mm is that acrylic resin mixes in 10: 2: 1 ratio.
6) on porous base course 2, lay permeable brick 3.
The vertical direction generalized section of the groove that vertically catchments on the ground after having spread; As shown in Figure 1, be followed successively by from bottom to up: crushed rock base course 4, breathable water repellant layer 1, porous base course 2, permeable brick; 5 grooves 6 that catchment have been formed in the final ground of having laid;
