Exploration of Anti-seepage Construction of Reservoir Embankments in Hydraulic Engineering——Through Taking a Reservoir in Jiangcheng District,Yangjiang City as an Example
Under the background of accelerating process of agricultural modernization,the construction scale of farmland water conservancy projects is gradually expanding,and the number of reservoir dam projects is gradually increasing.Higher requirements are put forward for construction quality.In addition to ensuring the stable and reliable operation of water conservancy projects,it is also necessary to prevent leakage and damage problems from occurring.The study starts with the causes of leakage in reservoir embankments in hydraulic engineering;and analyzes anti-seepage measures for reservoir embankments:the construction methods of grouting,anti-seepage walls,and monitoring,etc.Through taking a reservoir reinforcement project in Jiangcheng District,Yangjiang City as an example,the study discusses the process and methods of reservoir embankment reinforcement work.After the completion of the reservoir reinforcement construction,we should re-check whether the flood resistance of the dam meets the standard requirements,the weathering condition of the water level change area of the facing slope panel,whether there are cracks in the wave wall,and the entrance section of the spillway is seriously blocked,etc.The backfill of cast-in-place C25 concrete slope protection and back water slope surface from the top to the foot of slope is carried out to improve the stability and seepage prevention of the dam body.It is suggested to formulate the scientific risk reinforcement plan,and implement the reservoir dam concrete slope protection,and exit drainage channels dredging,etc.,so as to fully play the benefits of the reservoir.
