Problems solved by technology

[0002] In the creation of artificial water landscapes such as rivers and artificial lake revetments, the conventional practice is to set up concrete dams, earth-rock dams, and steel dams downstream to adjust the upstream landscape water surface and downstream ecological flow. The needs of the river, the cost of the steel dam is slightly higher

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0018] Embodiment of the present invention: a kind of dam crest overflow gabion structure ecological storage dam, as attached Figure 1-4 As shown, it includes the small flow overflow dam section and the overflow dam section on both sides of the two banks. The three dam sections are composed of multiple gabion structures connected to each other. The contact between the gabion structures or the ground There is an anti-seepage material layer 4 on the surface, and the binocular structure is a structure in which stones are filled into cages made of low-carbon galvanized plastic-coated steel wires and mechanically woven into hexagonal double-stranded steel wire meshes. The specification is L×1×h, L=1.5 / 2 / 2.5 / 3 / 3.5 / 4, h=1 / 0.5. During use, under the requirement of ensuring upstream water storage, the gabi...

Abstract

The invention discloses a crest overflowing Gebeng structure ecological water storage dam. The crest overflowing Gebeng structure ecological water storage dam comprises a small-flow overflow dam section and two side overflowing dam sections arranged a the two sides of the small-flow overflow dam section, wherein the three dam sections are formed by interconnecting multiple Gebeng structures; anti-seepage material layers are arranged among the Gebeng structures, or contact surfaces of the Gebeng structures and the ground are provided with the anti-seepage material layers; and the Gebeng structure is formed by filling aggregated rocks into net cages formed by mechanically weaving steel wires. Gebeng gabions, anti-seepage films, riprap egg collectors, artificial floating islands and water plants are combined and applied to the structure of the water storage dam, thus simultaneously meeting the requirements on the water storage of the water storage dam, water ecology, water landscape, construction cost and the like.

Description

technical field [0001] The invention relates to a water storage dam, in particular to an ecological water storage dam with a dam crest overflow gabion structure. Background technique [0002] In the creation of artificial water landscapes such as rivers and artificial lake revetments, the conventional practice is to set up concrete dams, earth-rock dams, and steel dams downstream to adjust the upstream landscape water surface and downstream ecological flow. For the needs of the river, the cost of the steel dam is slightly higher. In the design process of river control and barrage buildings, we should change the traditional concrete and masonry structures, and how to use permeable and breathable ecological protection materials and structural forms under the conditions of water retention and water storage to build ecological, economical and beautiful structures. The water storage dam becomes the urgent problem that those skilled in the art needs to solve. Contents of the in...
