Anti-erosion protection device for riverway corner

Abstract

The invention belongs to the technical field of water conservancy projects, particularly relates to an anti-erosion protection device for a riverway corner. In order to solve the problem that potential hazards caused by unpredictable flood impact force cannot be fundamentally solved by a conventional flood prevention means for the riverway corner, the invention provides the following scheme that the anti-erosion protection device comprises a concave bank side and a convex bank side, wherein the concave bank side and the convex bank side are both poured with reinforced concrete, the concave bank side comprises a vertical section, an arc section and an anti-scour section, cement bottoms are laid at the positions close to the concave bank side, of the river bottom of the arc section and the river bottom of the vertical section, and an adjusting box internally provided with a cavity and adopting a cuboid structure is fixed to the middle of one side away from the riverway, of the vertical section. An outer box with an opening facing the adjusting box is fixed to the back surface of the adjusting box, and a sliding bearing pedestal is slidably connected to the inner part of the outer box. According to the invention, the riverway can be prevented from being scoured and eroded by great water, and riverway sedimentation is prevented by changing river runoff.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to an anti-erosion protection device at a corner of a river course. Background technique [0002] In terms of embankment construction in the field of water conservancy, when there is a bend in the river, the embankment at the bend is the most severely eroded area by the river. And when the turning section of the river appears in urban areas or villages, once natural disasters such as rainwater surges occur, the water volume of the river will increase sharply, and it will easily overflow the embankment, posing a threat to the lives and properties of residents near the river. [0003] After searching, the Chinese patent number is CN201821643688.5, which discloses a flood control embankment structure at the bend of the river. When the embankment at the bend of the river is built, a flood control reinforcement structure is embedded in it in advance. At least two m...
