Abstract
The utility model discloses a storage yard structure on which an impermeable geomembranes is laid, which comprises a storage yard area (1), wherein the impermeable geomembrane (2) is laid on the storage yard area (1) and is formed by combining smooth laid sections (3) and corrugated laid sections (4); and a covering layer (5) is laid on the impermeable geomembrane (2). According to the storage yard structure, through laying the impermeable geomembrane in a manner of being formed by combining the smooth laid sections and the corrugated laid sections, the impermeable geomembrane at the corrugated laid sections can achieve elastic expansion and contraction in the grinding process, the deformable amount of the impermeable geomembrane can be increased, and the impermeable geomembrane cannot be ripped under the circumstance of large foundation deformation, so a good protection effect is achieved. When the impermeable geomembrane is laid, a laid layer of the impermeable geomembrane is firstly ground, so the foundation deformation amplitude after decompression and the tensile deformation probability of the impermeable geomembrane can be reduced.
Description
Technical field
The utility model relates to a kind of stockyard leakage preventing structure, particularly a kind of stockyard structure that is equipped with anti-seepage geomembrane.
Background technology
At industrial domestic refuses such as alumina laterite stockyard, the refuse landfill landfill place of banking up, the discarded object of landfill all has in various degree pollution to environment owing to bank up, therefore in process, all can relate to the application of anti-seepage geomembrane to bank up landfill yard design, construction.Anti-seepage geomembrane is generally laid in the landfill area of banking up by designing requirement, and the major function of the anti-seepage geomembrane fluid seepage that the industrial domestic refuse of landfill produces that is to prevent to bank up to reach the protection surrounding enviroment, prevents the contaminated purpose of underground water.Can find out the importance of laying anti-seepage geomembrane link in work progress thus.At present, the laying method of anti-seepage geomembrane is the Ground Treatment of going ahead of the rest, and lays anti-seepage geomembrane then, geomembrane is covered again, and cladding material generally adopts clay, carries out cal rolling at last.Yet there is defective in this method, and when cal rolling carried out, ground produced differential settlement owing to be compacted meeting.When differential settlement acquired a certain degree, anti-seepage geomembrane distortion may occur even by drawing crack, particularly at the perimeter strip place, because the border is generally fixed end, anti-seepage geomembrane is increased by the possibility of drawing crack, and this will bring hidden danger to environmental protection.
The utility model content
The technical problems to be solved in the utility model is: a kind of stockyard structure that is equipped with anti-seepage geomembrane that can prevent that when cal rolling anti-seepage geomembrane from breaking is provided, can overcomes the deficiencies in the prior art.
The technical solution of the utility model: it comprises the zone, stockyard, is equipped with anti-seepage geomembrane on the zone, stockyard, and anti-seepage geomembrane is made up of smooth laying section and the collocation of gauffer laying section, is equipped with covering layer on anti-seepage geomembrane.
Laying anti-seepage geomembrane is on the substratum through rolling.
The edge of anti-seepage geomembrane is fixed on the perimeter strip in zone, stockyard, is provided with gauffer on the perimeter strip next door and lays section.
Compared with the prior art; the utility model passes through laying anti-seepage geomembrane is a whole section and the gauffer laying section collocation composition form laid; the anti-seepage geomembrane of gauffer laying section just can be realized elastic telescopic in the process of rolling like this; increase its deformable amount; make anti-seepage geomembrane under the bigger situation of foundation deformation, also can not reached the better protect effect by drawing crack.Earlier it being laid layer when laying anti-seepage geomembrane rolls, can reduce post-decompression foundation deformation amplitude like this, reduce the stretcher strain probability of anti-seepage geomembrane, gauffer is laid section be arranged on the perimeter strip next door, anti-seepage geomembrane can also have elasticity surplus preferably on one side under fixing situation like this, has reduced perimeter strip place anti-seepage geomembrane and has been prone to the probability that breaks.
Figure of description
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, the first step rolls the substratum 6 that zone, stockyard 1 needs to lay anti-seepage geomembrane 2 places, makes its coefficient of consolidation that reaches designing requirement and characteristic value of foundation bearing capacity; Second step when laying anti-seepage geomembrane 2, was laid to the worker with anti-seepage geomembrane 2 and becomes shown in Figure 1 and lay the structures that section 3 and gauffer are laid section 4 collocation by smooth, and gauffer is laid section 4 and also be can be waveform, and its wavelength, the concrete engineering of crest height root are actual definite.In the 3rd step, it is fixing that anti-seepage geomembrane 2 is anchored into perimeter strip 7, and gauffer laying section 4 is adjacent with perimeter strip 7.The 4th step covered with 5 pairs of anti-seepage geomembranes 2 of covering layer, with machinery covering layer was rolled at last, and covering layer 5 generally can adopt barrier properties cohesive soil preferably.
Claims (3)
1. stockyard structure that is equipped with anti-seepage geomembrane, it comprises zone, stockyard (1), on zone, stockyard (1), be equipped with anti-seepage geomembrane (2), it is characterized in that: anti-seepage geomembrane (2) is made up of smooth laying section (3) and gauffer laying section (4) collocation, is equipped with covering layer (5) on anti-seepage geomembrane (2).
2. the stockyard structure that is equipped with anti-seepage geomembrane according to claim 1 is characterized in that: anti-seepage geomembrane (2) is laid on the substratum (6) through rolling.
3. the stockyard structure that is equipped with anti-seepage geomembrane according to claim 1 is characterized in that: the edge of anti-seepage geomembrane (2) is fixed on the perimeter strip (7) of zone, stockyard (1), is provided with gauffer on perimeter strip (7) next door and lays section (4).
