Bank scour prevention floating dam structure and bank scour prevention system

Abstract

The invention discloses a bank scour prevention floating dam structure and a bank scour prevention system, belongs to the technical field of water conservancy projects and engineering emergency rescue, and provides the bank scour prevention floating dam structure capable of slowing down the water flow speed of local parts of a bank and preventing the locally collapsed bank from being continuously scoured and damaged by flood. The bank scour prevention floating dam structure comprises a main chain, a floating box, a flow stop net and a traction rope; the lower end of the main chain is connected with a flow stop stone; the floating box is used for floating on the water surface; one end of the floating box is connected with the main chain; the upper edge of the flow stop net is suspended on the floating box; and one end of the traction rope is connected with the floating box. The bank scour prevention floating dam structure can effectively slow down the water flow speed of the local parts of the bank through the flow stop net structure, reduces continuous scouring and damage of the flood to the locally collapsed bank, and achieves an effective protection effect on the locally collapsed bank.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering and engineering emergency rescue, in particular to a bank dike scour prevention floating dam structure and a bank dike scour prevention system. Background technique [0002] Bank embankment is an important building to resist flood disaster along the river, but in flood season, it is eroded and scoured by flood water, causing embankment damage. Flood disasters seriously threaten the safety of people's lives and property, especially when long-term and large-scale rainfall causes river water levels to rise, and when banks and embankments partially collapse, if they are not repaired in time, once the embankment breaks, it will cause immeasurable and serious losses. [0003] At present, emergency protection for embankment collapse mainly focuses on slope protection and foundation consolidation to prevent embankment failure accidents. The main method is to form a temporary embankm...

AI Technical Summary

Problems solved by technology

[0004] The rescue and repair method of the above-mentioned embankment collapse consumes manpower and financial resources, and the construction period is long. It requires large-scale hoisting machinery to participate in hoisting, and has certain requirements for the working space.

If the embankment is deep, heavy objects such as anti-scour tetrahedral intercepting stones or stacked steel gabions need to be stacked and thrown, often because the river bottom is not smooth, or the heavy objects thrown first are not laid flat under the impact of the water flow, which affects other The stacking of heavy objects on the upper part can only be done by throwing multiple pieces of heavy objects in a large area. It is impossible to quickly build a temporary embankment to prevent the flood from continuing to scour the embankment, which may result in huge economic losses caused by embankment failure.
