[0002] Reservoir dams are important water conservancy engineering facilities, mainly used to prevent water from flowing and protect residents and farmland in downstream areas from floods. In the construction of small reservoir dams in towns and villages, earth-rock dams are widely used because of their low cost. However, earth-rock dams are at risk of being washed away when facing extreme weather and floods, which not only threatens people's lives and property safety, but may also cause serious economic losses. Therefore, strengthening reservoir dams and improving their impact resistance and stability are key measures to ensure regional water security.

[0003] At present, in order to reduce the impact of water flow on the slope of the dam and improve the impact resistance of the dam, geotextiles and protective plates are usually laid on the surface of the dam before the flood breaks out. Geotextiles play an important role in dam reinforcement due to their basic functions such as reinforcement and stabilization, filtration, isolation, drainage, and anti-seepage. Protective plates directly protect the surface of the dam and reduce soil erosion. These measures have improved the stability and safety of the dam to a certain extent.

A buffer reservoir dam reinforcement construction method, characterized in that: The method is applicable to a buffer reservoir dam reinforcement structure as described in any one of claims 1 to 7, and the steps of the method are as follows: S1: First, the L-shaped fixing plate (8) is pulled to drive the top of the connecting rib (10) to pass through the fixing hole (9), and the fixing nut (12) is tightened. Then, before the flood comes, the positioning rod (5) is manually pulled to drive one end of the geotextile (4) to pass through the hole (13), and the geotextile is laid on the slope of the dam. One end of the positioning fork (7) is used to pass through the positioning hole (6) to form a fixed connection with the dam. S2: According to the predicted water flow, the impact plate (26) is rotated around the hinge axis to adjust the support angle, and the magnetic adsorption strip (19) is driven to rotate to the side of the corresponding adjustment hole (30), and then one end of the locking bolt (31) is pulled through the locking hole (29) and the adjustment hole (30), and the locking nut (32) is tightened to complete the adjustment of the support angle of the impact plate (26); S3: When the water flow impacts the impact plate (26), the elastic characteristics of the energy-absorbing spring (27) and the damper (28) are used to absorb part of the impact force of the water flow, and the impact plate (26) is pushed to reset; S4: After the flood, the positioning fork (7) is pulled out and the driving handle (23) is rotated to drive the two driving gears (22) to mesh with each other and drive the two reeling rollers (3) to reel the geotextile (4). At the same time, the characteristics of the lifting spring (17) are utilized to push out the plate brush (16) in conjunction with the L-shaped resistance plate (18) to brush away foreign matter adhering to the surface of the geotextile (4); S5: After receipt is completed, the magnetic adsorption strip 1 (19) and the magnetic adsorption strip 2 (20) are used together to drive the positioning rod (5) and the main fixing plate (1) to form a stable connection, thereby reducing the loosening of the geotextile (4).
