Staggered type cyclopean wall imitated natural channel

Abstract

The invention provides a staggered type cyclopean wall imitated natural channel and belongs to the field of water conservancy projects. The staggered type cyclopean wall imitated natural channel comprises a concrete base, bank slopes, vertical seams, long cyclopean walls, short cyclopean walls, field building stones, a bottom slope, bottom slope boulders and a cyclopean sill. According to the imitated natural channel, the long cyclopean walls and the short cyclopean walls are arranged in the channel in a staggered mode to divide the imitated natural channel into a plurality of pools, and the vertical seams are reserved between the long and short cyclopean walls from side to side. The field building stones are laid on the concrete base to form the bank slopes, the bottom slope boulders are laid on the concrete base to form the sloping bottom slope, and the cyclopean sill is constructed at the bottoms of the vertical seams. According to the staggered type cyclopean wall imitated natural channel, the energy dissipation structure of traditional technical fish ways is optimized, and an eco-friendly migration channel is created for fishes; the manufacturing cost is low, the channel is suitable for large water level variation amplitude, the variety of passing fishes is large, and natural river ecological environment can be simulated; the staggered type cyclopean wall imitated natural channel is easy to rebuild after being constructed and is an ecological compensation project high in adaptability.

Description

technical field [0001] The invention relates to a fish passing facility technology in a water conservancy project, in particular to a staggered stone wall imitating a natural passage, which belongs to the technical field of water conservancy projects. Background technique [0002] Due to the needs of hydropower development and river flood control, many rivers are blocked by dams and dams of different types and sizes. In the mountains, with the help of high water head and large drop, people built dams and reservoirs to generate electricity and prevent floods by blocking rivers. These dams not only block the passage of migratory fish in the river, but also affect the downward transfer of upstream nutrients and the supplementation of fish fry in the upstream spawning area to downstream fishery resources. In plain areas, water conservancy projects such as tidal sluices, irrigation sluices, and drainage sluices not only block the access to rivers for fattening fish, but also blo...

AI Technical Summary

Problems solved by technology

These structures are not easy to adjust and rebuild after completion, and it is difficult to cope with water conservancy projects with a wide range of water level fluctuations and a large number of target fish species

Therefore, it is difficult to promote the use of traditional technical fishways
