The technical problems to be solved in the utility model is to provide a kind of rainwater guide gathering system of can water conservancy diversion, collecting the rainwater on junk-heap body, this rainwater guide gathering system can realize the dirty shunting of rain, minimizing rainwater enters junk-heap body, thereby reduces the generation of percolate.
In order to solve the problems of the technologies described above, the utility model provides a kind of rainwater guide gathering system of refuse landfill, comprising:
The rainwater-collecting ditch arranging along junk-heap body bottom;
The rainwater-collecting hole being communicated with described rainwater-collecting ditch;
Cover the coverlay of junk-heap body and rainwater-collecting ditch;
Press solidly the ballasting system of described coverlay, comprise the netting and a plurality of sandbag being pressed on described netting that are layed on described coverlay.
Also comprise the rainwater curb that has a common boundary and arrange along the low level of the adjacent guide face of described junk-heap body, on described rainwater curb, be coated with described coverlay.
The size of mesh opening of described netting is 250*250mm, and its rope footpath is Φ 8-12mm.
The gradient of described guide face preferably >=5 ‰.
Described rainwater-collecting hole is laid and is welded with film by inside, ， cofferdam, packed clay cofferdam, is wherein provided with float-controlled drainage pump.
Between described rainwater-collecting hole and rainwater-collecting ditch, by rainwater guide ditch, be communicated with, on described rainwater guide ditch, be coated with described coverlay.
Described coverlay is along the suitable high overlap joint that forces down of slope direction, and lap width is about 20cm.
Described coverlay is the HDPE film of 0.5mm.
The rainwater guide system of the utility model junk-heap body comprises coverlay and the ballasting system thereof covering on junk-heap body and each curb and guide ditch, prevents that rainwater from infiltrating in junk-heap body; Also comprise and there is the rainwater curb that a plurality of low levels along adjacent guide face have a common boundary and arrange, described rainwater curb can be guided to rainwater junk-heap body bottom, prevent that rainwater is stranded on junk-heap body, and be provided with rainwater-collecting ditch bottom junk-heap body, with the unified rainwater of collecting from guide face and rainwater curb, and by rainwater guide ditch, rainwater guide to rainwater-collecting is cheated, described rainwater-collecting is provided with float-controlled drainage pump in hole, in time rainwater is carried out to pump drainage.If desired, can repair slope to junk-heap body blockette, make to arrange on junk-heap body a plurality of rainwater curbs.Technique effect of the present utility model is: by said structure is set, the rainwater on water conservancy diversion, collection guide junk-heap body, realizes the dirty shunting of rain, effectively prevents that rainwater from infiltrating junk-heap body, reduced the generation of percolate largely.

The specific embodiment
Before this rainwater guide gathering system is set, first need on junk-heap body 10, build the guide face 101 that is applicable to rainwater guide, the domatic monolithic finish that carries out of junk-heap body is rolled, fill and lead up hollow, accomplish more smooth-going domatic, guarantee rainwater-collecting ditch 60(that rainwater can flow to junk-heap body bottom along guide face 101 referring to Fig. 1 and below), the gradient of described guide face 101 is preferably >=5 ‰.
If junk-heap body is larger, be not suitable for the domatic monolithic finish that carries out, referring to the junk-heap body 10 in Fig. 1, described junk-heap body 10 needs blockette according to the method described above to repair slope, along the low level of adjacent guide face 101 have a common boundary (being the low-lying place that each block is adjacent) repair the rainwater curb 103 that leads to junk-heap body 10 bottoms, make to arrange on junk-heap body 10 a plurality of rainwater curbs 103.Because described rainwater curb 103 is positioned at the lowest part of the guide face 101 of each block, under the effect of gravity, rainwater not only can flow to junk-heap body 10 bottoms along guide face 101, also can flow to junk-heap body 10 bottoms along rainwater curb 103, is discharged to unified collection in rainwater-collecting ditch 60.
As shown in figures 1 and 3, described rainwater-collecting ditch 60 arranges along described junk-heap body 10 bottoms (be slope at the bottom of), the unified rainwater flowing down from above-mentioned a plurality of guide faces 101 and rainwater curb 103 of collecting.At the bottom of the bottom of the reservior of refuse landfill or subordinate field, be provided with rainwater-collecting hole 80, described rainwater-collecting cheats that 80 physical features are lower than rainwater-collecting ditch 60, and both are communicated with by rainwater guide ditch 61, and the Water in Rainwater Drainage in guiding rainwater-collecting ditch 60 is to described rainwater-collecting hole 80.Described rainwater-collecting hole 80 adopts inside, ， cofferdam, packed clay cofferdam to lay welding with film, forms a provisional water storage hole, is wherein provided with float-controlled drainage pump 801, in time rainwater is carried out to pump drainage, to repeatedly circulate draining, as shown in Figure 5.
As shown in Figure 1, Figure 2 and Figure 3, described junk-heap body 10(comprises guide face 101 and rainwater curb 103), be coated with coverlay 40 on rainwater-collecting ditch 60 and rainwater guide ditch 61, described coverlay 40 is preferably the HDPE film of 0.5mm, take along the high form of forcing down nature overlap joint of slope direction, lap width W is about 20cm.Described HDPE film is impermeability film, plays and stops that rainwater enters the generation of junk-heap body 10, minimizing percolate.
For fixing coverlay 40, the utility model also comprises ballasting system 70, as shown in Figure 2 and Figure 4, described ballasting system 70 has uvioresistant netting 705 and a plurality of sandbag 703 being pressed on described netting 705 being layed on described coverlay 40, the specification of described netting 705 is as follows: size of mesh opening is 250*250mm, and rope footpath is Φ 8-12mm.
