装配式L形挡墙在某护岸工程中的应用

近年来，水运、水利工程中常用的现浇混凝土挡墙形式越来越难以满足行业高节能性、环保性、经济性的要求，装配式护岸结构逐渐被关注，但在水运、水利工程中的实际应用经验尚不足。结合某护岸工程装配式L形挡墙实施实例，归纳总结了装配式护岸在工程应用中的重难点，并从工程建设条件、护岸结构选型、构件拆分与连接、构件制作、吊运安装等设计和施工中的关键技术等方面进行分析研究，形成一套较完整的装配式L形护岸设计施工技术要点，为装配式护岸在类似工程的推广应用提供可参考的解决思路。

Application of prefabricated L-shaped retaining walls in a revetment project

In recent years, the cast-in-place concrete retaining walls commonly used in water transport and water conservancy engineering have encountered increasing difficulties in satisfying the demanding requirements of energy saving, environmental protection, and economy of the industry.Meanwhile, the prefabricated revetment structure has gradually attracted attention, but it lacks practical application in water transport and water conservancy engineering.Accordingly, via analyzing a practical example of prefabricated L-shaped retaining walls in a revetment project, the paper summarizes some key and difficult points in the engineering application of prefabricated revetment structures.In addition, it probes into the key technologies in the design and construction, such as engineering construction conditions, revetment structure selection, splitting and connection of members, member fabrication, and lift installation.With these efforts, it formulates a complete set of knowledge on the key technical points of the design and construction of prefabricated L-shaped revetments, proffering references for the application of prefabricated revetments in similar projects.
