Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a fishway structure combined with rock wall support. Background Technology

[0002] Fishways are channels for fish migration. They are remedial measures taken when human activities disrupt these channels, typically by constructing artificial channels on sluice gates or dams to protect fish behavior. Currently, there are many types of fishways, mainly including technical and ecological fishways such as vertical slot fishways, pool-type fishways, and baffle-type fishways (Daniel fishways). Traditional fishways often use reinforced concrete cast-in-place structures, resulting in long construction periods, complex layouts, and large land occupation. Furthermore, the layout of fishways can affect the structure of sluice gates or the slope of side slopes, causing damage to existing hydraulic engineering projects. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fishway structure that combines rock wall support, which can solve the problems of long construction period, large land occupation, and great impact on the original water conservancy project of traditional fishway.

[0004] Therefore, the present invention adopts the following technical solution: A fishway structure combined with rock wall support includes an anchoring structure fixed to the rock wall, a fishway support structure fixed to the end of the anchoring structure away from the rock wall, and a prefabricated fishway box structure fixed to the fishway support structure.

[0005] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions: The anchoring structure includes several prestressed anchor rods, one end of which is embedded inside the rock wall for anchoring.

[0006] The fishway support structure includes a pad and a support beam. The pad is fixed to the end of the prestressed anchor rod that protrudes from the rock wall, and the support beam is fixed to the side of the pad. The bottom surface of the prefabricated box structure is placed on top of the support beam.

[0007] The prestressed anchor rod has one end protruding from the rock wall that passes through the pad and has threads. The prestressed anchor rod is fastened to the pad by a nut.

[0008] Several auxiliary bolts are also fixed on the pad, with one end of each auxiliary bolt embedded in the rock wall to limit the swaying of the pad.

[0009] The prefabricated fishway box structure includes a straight box section and a bent box section. One end of the straight box section and / or the bent box section is provided with a partial narrowing joint for nested connection. Two straight box sections can be nested and connected, and the straight box section can be nested and connected with the bent box section.

[0010] The prefabricated fishway box structure also includes minor turbulence plates that are staggered and fixed to the inner wall of the box.

[0011] The bent box section is a backbend structure.

[0012] Several of the prestressed anchor rods are arranged along the extension direction of the prefabricated fishway box structure, with a spacing of 2m to 3m between the anchor rods.

[0013] The support beam is a T-shaped beam plate, and the support beam is fixed to both sides of the pad plate.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects: it combines the design of slope support anchor rods to form an anchoring structure on the rock wall. The main body is a prefabricated fishway box structure, which does not require additional excavation site, occupies less land, is easy to assemble, greatly reduces the construction cycle and is not affected by the original water conservancy project and excavation terrain.
