Description
Technical field
The utility model belongs to the garbage loading embeading field, particularly the antiseepage film laying structure of the concave-convex type side slope of valley type landfill.
Background technology
In the south China area, mostly be hilly ground, mountain valley is numerous, for saving construction cost, the valley type landfill of take full advantage of the mountain valley pre-existing topography, building by the mountain arises at the historic moment, and described valley type landfill is by being divided into multi-stage platform, being repaiied slope compacting the antiseepage film of mating formation and process and form by certain height difference the mountain valley side slope.The schematic top plan view of massif side slope as shown in Figure 1, between the toe extended line 15 of the anchored platform 14 of elevation and low elevation, the massif side slope, because the relation in ridge and mountain valley is the concavo-convex irregular form replaced, forms matrix side slope 11 and convex side slope 12.
Referring to Fig. 2, except for non-concavo-convex side slope 13, arrange perpendicular to the vertical antiseepage film 32 between side slope top and bottom, in prior art, refuse landfill is as follows to the processing mode of concave-convex type side slope: cut out the polylith triangle antiseepage film 30 with matrix side slope 11 or the 12 adaptive laminatings of convex side slope, the described triangle antiseepage film 30 of mating formation successively, until cover whole matrix side slope 11 or convex side slope 12, form fan-shaped cambered surface leakage preventing structure.When the radian of matrix side slope 11 or convex side slope 12 hour, this fan-shaped cambered surface leakage preventing structure can be obtained good result, but when radian is larger, a large amount of single track weld seams are assembled at cambered surface inside lock 31 places of this leakage preventing structure, cause stress to be concentrated,, there is larger potential safety hazard in structural instability.
The utility model content
The technical problems to be solved in the utility model is to provide and a kind ofly reduces weld seam quantity on the concave-convex type side slope, avoids stress to concentrate, improve the antiseepage film laying structure of structural stability.
In order to solve the problems of the technologies described above, the utility model provides a kind of antiseepage film laying structure of concave-convex type side slope, comprise along the center line antiseepage film of the center line setting of matrix side slope or convex side slope and be located at center line antiseepage film both sides and cover respectively the multi-disc domatic antiseepage film side by side of its two side slope, described domatic antiseepage film one end is connected with described center line antiseepage film side inclined slope aspect, and the other end is located at the anchored platform at top or the toe extended line of bottom.
Described center line antiseepage film and domatic antiseepage film are roughly bar shaped, and described domatic antiseepage film connects side by side by side.
The domatic antiseepage film of each described center line antiseepage film one side and the domatic antiseepage film of opposite side are splayed and distribute.
Described domatic antiseepage film is perpendicular to the toe extended line of anchored platform or the convex side slope of matrix side slope.
Outermost domatic antiseepage film away from described center line is connected by side with the vertical antiseepage film on being laid on non-concavo-convex side slope.
Compared with prior art, the utility model comprises that the center line antiseepage film and the many rows that are located at matrix side slope or convex side slope center line are located at center line antiseepage film both sides and cover respectively domatic domatic antiseepage film, the side inclined slope aspect of described domatic antiseepage film one end and center line antiseepage film overlaps and welds, the other end is vertical at the anchored platform at matrix side slope top or the toe extended line of convex side slope bottom, this structure decrease antiseepage film is the weld seam quantity at cambered surface inside lock place especially, avoid stress to concentrate, improve the structural stability of the domatic upper antiseepage film of concave-convex type, and domatic or convex is domatic all applicable to the matrix of any radian size, applicable surface is wider, practicality is stronger.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The schematic top plan view that Fig. 1 is the massif side slope.
The antiseepage film laying structure schematic diagram that Fig. 2 is concave-convex type side slope in background technology.
The antiseepage film laying structure schematic diagram that Fig. 3 is the utility model concave-convex type side slope.
The specific embodiment
As shown in figures 1 and 3, the utility model comprises that shape is roughly center line antiseepage film 51 and the domatic antiseepage film 52 of bar shaped, described center line antiseepage film 51 is arranged at along the center line 17 of matrix side slope 11 and convex side slope 12 between the toe extended line 15 of the anchored platform 14 at top and bottom, described center line 17 be matrix side slope 11 and convex side slope 12 domatic vertically in separated time.The domatic antiseepage film 52 that the multi-disc side connects side by side is located at described center line antiseepage film 51 both sides and is covered respectively the domatic of center line antiseepage film 51 left and right sides, the side inclined slope aspect overlap joint of described domatic antiseepage film 52 1 ends and described center line antiseepage film 51 welding with it, the other end is located at the toe extended line 15 of anchored platform 14 and the convex side slope 12 of matrix side slope 11, and domatic antiseepage film 52 and the domatic antiseepage film 52 of opposite side of each described center line antiseepage film 51 1 side is splayed and distributes.Described " inclined slope aspect " is defined as the direction of domatic normal projection on horizontal plane from eminence to lower.
As shown in Figure 3, when antiseepage film is installed, the domatic antiseepage film 52 on matrix side slope 11 is vertical with described anchored platform 14, and the domatic antiseepage film 52 on convex side slope 12 is vertical with described toe extended line 15.Outermost domatic antiseepage film 52 away from center line 17 is connected by side with the vertical antiseepage film 32 on being laid on non-concavo-convex side slope 13.
Before installation, at first measured and cutting, carefully measure the size of required center line antiseepage film 51 and domatic antiseepage film 52 on matrix side slope 11 and convex side slope 12 with mark post and tape measure, and make a record; After measurement completes, according to record, carry out cutting, described center line antiseepage film 51 is a monoblock antiseepage film, and domatic antiseepage film 52 need be carried out cutting with the oblique lap-joint of center line antiseepage film 51, guarantees that overlap joint is smooth.During installation, at first along the center line 17 of matrix side slope 11 and convex side slope 12, lay center line antiseepage film 51, re-lay domatic antiseepage film 52, until be connected with the vertical antiseepage film 32 on non-concavo-convex domatic 13.By changing shape and the paving structure of antiseepage film, the weld seam quantity of the antiseepage film on matrix side slope 11 and convex side slope 12 reduces, and particularly the weld seam quantity at cambered surface inside lock place reduces greatly, has avoided the stress at this place to concentrate, improve structural stability, no matter domatic radian is much all applicable; Can also reduce spillage of material, profile is more attractive in appearance.
