Embodiment Construction

[0008] Such as figure 1 As shown, the rolling dam building structure suitable for ecological water landscapes of the present invention includes a gravity rolling dam 2 built on a plain concrete foundation 1 made of concrete or mortar and masonry, and the downstream of the gravity rolling dam 2 The side is a slope type multi-stage energy dissipation step 3 structure.

[0009] In order to facilitate the reduction of high water head, the gravity rolling dam 2 is arranged as far as possible in the position of the main river channel, and the length of the dam body is determined according to the width of the passing water. When operating at different water levels in rivers and lakes, the dam elevation is determined according to various high water level calculations. The energy dissipater of the dam, that is, the number and size of the slope-type multi-level energy dissipating step 3, can be determined according to the drop after the water flows through the dam. The water velocity and ...

Abstract

The invention discloses an overflow dam building structure suitable for an ecological water landscape. The overflow dam overflow dam comprises a gravity type overflow dam built on a plain concrete foundation and built by concrete or masonry-mortar-stones, and the downstream side of a dam body of the gravity type overflow dam is of a slope type multistage energy dissipation step structure. The overflow dam building structure has the advantages that the retaining dam is set to be the gravity type overflow dam and the downstream side of the dam body is designed to be of the slope type multistage energy dissipation step structure so that erosion resistibility and stability of the gravity type overflow dam are improved and the whole building structure is led to be simple in form, small in steel bar consumption and fast in construction. In addition, perfect combination of landscape performance and ecological performance is achieved, and the project benefits of sufficiently utilizing hydroelectric resources, greatly saving project investment and improving the river way embankment water landscape are achieved.

Description

Technical field [0001] The invention relates to a retaining dam used for the natural water body and artificial water body of the ecological water area of ​​the river bank, in particular to the building structure of the rolling dam. Background technique [0002] In the development and management of river courses, lake banks and natural and artificial water landscapes, when the water in the river courses and lakes flows from high to low, the water head is dissipated by setting up dams to dissipate energy, and various forms are generated by the use of head height differences The falling water and waterfalls can use the head to form the abundant water movement, rhythm and speed, and create a variety of water landscapes. The current common practice is to set up rubber dams at different elevations. However, this type of gate dam controlled by inflatable rubber has a complicated structure and high investment, and after a certain number of years of use, the rubber aging causes the entir...
