Problems solved by technology

[0003] The movable landscape dams built on urban rivers include: sluice gates, rubber dams, flap gate dams, steel dam gates and pneumatic gates, etc. These movable dams are either high in cost, poor in reliability and durability, or not aesthetically pleasing; in addition, The existing concrete or masonry fixed ecological landscape dams have poor landscape effect

Embodiment Construction

[0023] The present invention is described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Such as figure 1 As shown, an embodiment of a water curtain cave ecological landscape dam of the present invention includes a main dam body 1, a water drop platform 2, a water curtain cave corridor 3, a stilling pool 4 and auxiliary facilities 5.

[0025] In this embodiment, the dam axis of the main dam body 1 is in the form of an arc arching toward the upstream, the upstream facing surface 11 is perpendicular to the horizontal plane, the downstream dam surface is in the form of an arc curved upstream, and the cross section of the main dam body 1 is " "" shape, that is concave toward the upstream, and the whole is made of reinforced concrete. The main dam body 1 crosses the river to raise the water level, store water in the river, and form a landscape lake, especially to ensure the ecology of the river in the dry season. water consumption....

Abstract

The invention discloses a water-curtain-cave-type ecological landscape dam comprising a main dam body (1). The main dam body (1) is composed of an upstream face (11), a top overflow face (12) and a dam toe terrace (13); the main dam body is arranged on a river channel in a crossing mode; the top overflow face extends towards the downstream to form a drop platform (2); the drop platform and the downstream side of the main dam body form an arc-shaped cantilever-type overhanging eave structure (32), and the dam toe terrace is located below the arc-shaped cantilever-type overhanging eave structure; a water curtain cave corridor (3) is arranged between the arc-shaped cantilever-type overhanging eave structure and the dam toe terrace; water flowing down from the drop platform forms a drop watercurtain, and stepping stone for people passing (31) is laid in the water curtain cave corridor; and a stilling pool (4) is arranged on the downstream of the water curtain cave corridor. The water-curtain-cave-type ecological landscape dam has the advantages of being good in durability, low in cost, safe and reliable in operation, good in hydrophilic effect, high in landscape ecological effect andthe like.

Description

technical field [0001] The invention relates to an ecological landscape dam, in particular to a water curtain cave type ecological landscape dam. Background technique [0002] In recent years, with the concept of beautiful countryside construction and ecological water conservancy, as well as the continuous innovation and development of water conservancy and hydropower projects, and the rapid development of social economy, people's requirements for water landscape and water ecological construction are increasing day by day. For the construction of barrages and dams in urban river management projects, new requirements are put forward in terms of ecology, landscape, and hydrophilicity. [0003] The movable landscape dams built on urban rivers include: sluice gates, rubber dams, flap gate dams, steel dam gates and pneumatic gates, etc. These movable dams are either high in cost, poor in reliability and durability, or not aesthetically pleasing; in addition, The existing concret...
