Description

Technical Field

[0001] The utility model relates to the technical field of river channel protection, in particular to a safety protection device for water conservancy construction. Background Art

[0002] In water conservancy projects, the main reason for the need for protection of downstream rivers is to prevent the river water from eroding the downstream riverbed and bank slopes, causing flood disasters and ecological environmental damage. Building a stable river bank in the downstream river can play a big role, but in the event of heavy rain, the downstream river is usually located at the exit of a catchment area, which is the drainage outlet of a large area of ​​nearby land. When the rainfall in the catchment area exceeds the carrying capacity of the river, the flow of the river increases. If the protection measures of the river bank are not complete, overflow is likely to occur. The staff will immediately build a row of water retaining steel plates on the river bank of the downstream river to increase the height of the river bank for protection, to prevent the water level from overflowing the river bank of the downstream river and causing damage to the surrounding ecological environment.

[0003] At present, the construction of existing water-retaining steel plates first requires transporting a batch of steel plates to the site, and then moving the steel plates for construction. During the assembly process, the steel plates need to be fixed and spliced ​​manually using tools and bolts. Manually tightening multiple sets of bolts is required for fixing, which makes the assembly of steel plates more troublesome and therefore not quick and convenient enough. Utility Model Content
