Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wastewater ponds, in particular to an anti-seepage heavy metal wastewater pond. Background Art
[0002] In the environmental protection transformation of old factories, a large number of wastewater treatment ponds and storage ponds are required. Directly excavating and newly building anti-seepage ponds is costly, time-consuming, consumes a large amount of area, and involves a large amount of earthwork problems. The original ponds are severely damaged. After anti-seepage treatment, when the water level in the ponds is low during water storage, due to the relatively high groundwater level, the ponds will float, posing a major safety hazard. Thickening the bottom slab of the original pond affects the water storage capacity of the pond. Therefore, a technology for transforming old wastewater ponds is needed to improve the functions of the original ponds, solve leakage points, and increase anti-seepage, anti-floating, strengthening and reinforcement functions, and upgrade the standard of the ponds in the shortest time to avoid affecting normal production. Content of the Utility Model
[0003] In order to solve the above technical problems, the utility model provides an anti-seepage heavy metal wastewater pond.
[0004] The specific scheme of the utility model is as follows: an anti-seepage heavy metal wastewater pond, including a pond bottom base layer formed by bricklaying, a layer of reinforced concrete layer is cast on the inner surface of the pond bottom base layer, a layer of geomembrane is laid on the upper surface of the reinforced concrete layer, a first layer of concrete is cast on the upper surface of the geomembrane, a layer of geotextile is laid on the upper surface of the second layer of concrete, and a second layer of concrete layer is provided on the upper surface of the geotextile.
[0005] Preferably, both the first layer of concrete and the second layer of concrete adopt C30 plain concrete.
[0006] Preferably, the thickness of both the first layer of concrete and the second layer of concrete is 10 - 15 cm.
[0007] Preferably, the thickness of the reinforced concrete layer is 20 - 30 cm.
[0008] Preferably, the geomembrane adopts HDPE geomembrane.
[0009] Compared with the prior art, the utility model has the following beneficial effects: It is applicable to the transformation of wastewater ponds in old factories, enabling them to obtain anti-seepage functions to meet environmental protection requirements. Description of the Drawings
