An artificial lake anti-seepage structure

Abstract

The invention relates to an artificial lake anti-seepage structure, which relates to the technical field of garden artificial lake anti-seepage, which includes a rammed earth layer, a clay layer, a planting soil layer and a water-resistant layer, the compaction degree of the rammed earth layer is greater than 0.85, and the rammed earth layer The upper surface of the layer shall ensure that the flatness per square meter does not exceed 20mm, and there are no obvious holes; the clay layer is laid on the upper surface of the rammed earth layer, and the clay layer is clay or commercial montmorillonite with a clay content greater than 30%; planting The soil layer is laid on the upper surface of the clay layer, and the water-proof layer is arranged on the upper surface of the planting soil layer. The water-proof layer includes a plurality of water-proof tiles, and the water-proof tiles are evenly distributed in the length direction and width direction of itself. The water-proof tiles are laid on the planting soil layer, and the water-proof tiles are provided with planting holes for the plants to pass through. The invention has the effect of conveniently cleaning the silt at the bottom of the lake, and is not easy to damage the planting soil layer at the bottom of the lake when cleaning the silt, reduces the frequency of re-construction on the bottom of the artificial lake, and saves resources.

Description

technical field [0001] The invention relates to the technical field of anti-seepage of garden artificial lakes, in particular to an anti-seepage structure of artificial lakes. Background technique [0002] Artificial lakes are generally a kind of lake dug out by people in a planned and purposeful way, and are produced in an unnatural environment. Most of the artificial lakes are used to hold back flood water and regulate water flow. In some places, artificial lakes exist in the form of landscapes and beautiful scenery. The water loss of artificial lakes is through evaporation and leakage. The former cannot be avoided, while the latter needs to be solved by formulating corresponding technical means. The artificial lake that exists as a beautiful scenery must consider the problem of water loss. If the water loss of the artificial lake is too fast, it will seriously waste water resources. [0003] At present, the public date is December 27, 2019, and the Chinese invention pat...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned existing technical solutions have the following defects: after the artificial lake is used for a period of time, the sedimentation of silt will inevitably occur. After the silt accumulates too much, it will affect the growth of green plants and make the artificial lake shallower. If the silt is not cleaned for a long time It will also destroy the water quality in the artificial lake. In the above-mentioned technical scheme, due to the arrangement of the HDPE film and the GCL layer, it is not convenient to use an excavator to dredge the artificial lake, and the GCL layer is laid with planting soil. The water is drained, and then the silt is washed by spraying water, and the planting soil will be washed along with the silt, and finally the planting soil layer becomes thinner and thinner. Therefore, the above technical solution is not convenient to use spray dredging
