Abstract
The utility model discloses an ecological seepage prevention structure of plant at the bottom of artificial lake, solved current artificial lake bottom of the lake barrier layer and appeared a large amount of infiltration and the relatively poor problem of lake water quality easily. The soil layer ramming method comprises a rammed lake bottom original soil layer (1), wherein a first clay layer (2) is arranged on the rammed lake bottom original soil layer (1), a first anti-seepage composite geomembrane (3) is arranged on the first clay layer (2), a second clay layer (4) is arranged on the first anti-seepage composite geomembrane (3), a second anti-seepage composite geomembrane (5) is arranged on the second clay layer (4), a planting soil layer (6) is arranged on the second anti-seepage composite geomembrane (5), and emergent aquatic plants (7) are planted on the planting soil layer (6). Effectively prevents the leakage of the lake water and realizes the self-purification function of the lake water.
Description
Technical Field
The utility model relates to a lakebed seepage prevention structure of an artificial lake, in particular to a plant ecological seepage prevention structure arranged at the bottom of the artificial lake.
Background
Along with the development of social economy, the urban artificial lake landscape becomes an important component of the construction of urban infrastructure, and the design and construction of the artificial lake seepage-proofing structure become an important problem to be solved in the construction; the seepage prevention of the bottom of the artificial lake refers to: in order to prevent the continuous degradation of the lake water ecosystem and protect and save water resources, the artificial lake needs to adopt comprehensive water-saving and water-replenishing measures to prevent the excessive leakage of the lake water; the prior art generally comprises the following steps of constructing the bottom of an artificial lake: excavating artificial lake earthwork to the position of the lake bottom, tamping undisturbed soil of the lake bottom, backfilling a fine sand cushion layer with the thickness designed by a drawing, paving a polypropylene film-coated woven cloth double-sided non-woven fabric impermeable film (waterproof material), backfilling a sand stone cushion layer on the waterproof material, and paving pebbles or gravel materials on the sand cushion layer; the lake bottom seepage-proofing structure has the following problems: (1) when the artificial lake stores water, water pressure directly acts on the impermeable membrane through the sand cushion layer and the pebbles, so that the impermeable membrane is easily pierced by the corners of the pebbles, meanwhile, the water pressure passes through the sand cushion layer and the pebbles to tear the impermeable membrane, particularly, the impermeable membrane is more easily torn on the inclined lake bottom surface, and after the impermeable membrane is displaced, the impermeable membrane is cracked frequently, so that a large amount of water leakage at the lake bottom is caused; (2) the maintenance difficulty of the impermeable layer is high, and the maintenance cost is high; (3) the self-purification ecological system of lake water can not be established on the anti-seepage structure of the lake bottom, so that the quality of the lake water is poor.
Disclosure of Invention
The utility model provides an ecological seepage prevention structure of plant at the bottom of artificial lake, solved current artificial lake bottom of the lake barrier layer and appeared a large amount of infiltration and the relatively poor technical problem of lake water quality easily.
The utility model discloses a solve above technical problem through following technical scheme:
an artificial lake bottom plant ecological seepage-proofing structure comprises a tamped lake bottom original soil layer, wherein a first clay layer is arranged on the tamped lake bottom original soil layer, a first seepage-proofing composite geomembrane is arranged on the first clay layer, a second clay layer is arranged on the first seepage-proofing composite geomembrane, a second seepage-proofing composite geomembrane is arranged on the second clay layer, a planting soil layer is arranged on the second seepage-proofing composite geomembrane, and emergent aquatic plants are planted on the planting soil layer.
The thickness of the first clay layer and the thickness of the second clay layer are both 300 mm, and the thickness of the planting soil layer is 800 mm.
The utility model discloses a set up the compound geomembrane of prevention of seepage between the clay layer, prevented the seepage of lake water effectively, protected the compound geomembrane of prevention of seepage complete with avoid being torn to through plant emergent aquatic plants on the planting soil layer at the bottom of a lake, realized the self-purification function of lake water.
