Description

Technical Field

[0001] The utility model relates to the technical field of waterway engineering, and particularly relates to a protection device for the bank slope of a waterway regulation project. Background Technique

[0002] The waterway regulation project refers to building special regulation structures or other engineering measures in the riverbed to adjust the riverbed morphology and the water and sediment flow path, so as to form a favorable water flow structure, utilize the power of the water flow itself to scour the waterway and maintain the stability of the waterway, and ensure the necessary navigation dimensions of the waterway during the low water period. The purpose of waterway regulation is to use regulation structures to adjust the relationship between the water flow and the riverbed, locally change the evolution process of the riverbed, thereby adjusting the erosion and deposition of the riverbed, making the water flow scour occur where it is needed, the sediment deposit where it is expected, and maintaining the relative stability of the riverbed.

[0003] When the traditional waterway regulation rectifies the bank slope, it usually uses a protection net for covering and rectifying. However, after long-term use, the protection net will slide or settle from the surface of the bank slope under the influence of the water level rise and fall, which will cause the loss of sand and gravel on the bank slope and damage to the waterway. For this reason, we provide a protection device for the bank slope of a waterway regulation project to solve the above problems. Content of the Utility Model
