Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reinforcing devices, in particular to a dam anti-seepage water-retaining buffer device. BACKGROUND

[0002] The riverbank dam has hidden dangers in the flood season, and the dam seepage damage is the most common danger. The dam seepage damage has several obvious characteristics, including soil flow, contact erosion, and contact soil seepage. Once the seepage danger occurs, it needs to be timely warned and disposed to avoid the serious consequences of dam collapse and gap caused by seepage.

[0003] The main means of riverbank dam flood control at present is to install a water baffle and fill sandbags. However, the above measures are mainly located on the outer surface of the dam body, mainly dealing with the danger brought by the rising water level in the flood season. However, the seepage danger is located inside the dam body and will cause dam collapse with soil loss. Therefore, the effect of sandbags on this danger is not good. The current disposal methods are various, including ramming a water baffle inside the dam and filling soil between the dam and the water baffle to block the seepage point. However, the water baffle needs to withstand the impact of water flow, and the impact force is large, which is easy to deform and tilt. Therefore, a new type of water-retaining device is considered to be designed to reduce the impact of water flow and weaken the impact of water flow on the rear dam to gain more time for dam reinforcement. In view of this, we propose a dam anti-seepage water-retaining buffer device. SUMMARY
