水下抛石在西江干流治理工程中的应用实践

Application of Underwater Riprap in Xijiang Main Stream Treatment Project

在治理江河堤防险工险段时,水下抛石护岸是一种较为有效的治理方法,其通过在崩岸地段抛置一定厚度块石层来提高堤岸的抗冲刷能力和结构稳定性,能够起到稳定河势、保护堤岸的目的。但是,水下抛石作业施工量大、容易受到多种因素影响,导致其作业质量往往难以得到保障。对此,深入研究水下抛石工艺,以西江干流治理工程为依托研究水下抛石作业的应用实践方法,以期为广大技术与作业人员提供一定指导,最终推动我国河流治理工作的持续发展。

Underwater riprap revetment is a more effective treatment method when controlling the dangerous section of river embankment.It can improve the anti scour ability and structural stability of the embankment by throwing a certain thickness of block stone layer in the bank collapse section,which can stabilize the river regime and protect the embankment.However,underwater riprap operation has a large amount of construction and is easy to be affected by many factors,resulting in its operation quality is often difficult to be guaranteed.In this regard,we should deeply study the underwater riprap technology and study the application and practical methods of underwater riprap operation based on Xijiang main stream treatment project,in order to provide certain guidance for the majority of technicians and operators,and finally promote the sustainable development of river treatment in China.
