主要介绍港珠澳大桥沉管预制厂深浅坞挡水构筑物及其止水系统设计。挡水构筑物主要由防渗处理过的原状岩石山体和重力式沉箱拦水坝结构组成。止水系统设计的重点包含重力式沉箱拦水坝和岩石坝基之间的防渗，拦水坝结构与原状岩石山体连接处的防渗以及原状岩石山体的防渗处理。主要采用注浆防渗的处理方法，结合预埋Z9-30橡胶止水带以及现浇素混凝土等进行防渗设计。
主要介紹港珠澳大橋沉管預製廠深淺塢擋水構築物及其止水繫統設計。擋水構築物主要由防滲處理過的原狀巖石山體和重力式沉箱攔水壩結構組成。止水繫統設計的重點包含重力式沉箱攔水壩和巖石壩基之間的防滲，攔水壩結構與原狀巖石山體連接處的防滲以及原狀巖石山體的防滲處理。主要採用註漿防滲的處理方法，結閤預埋Z9-30橡膠止水帶以及現澆素混凝土等進行防滲設計。

Mainly introduces the structure design of the deep&shallow basin water-stop bund and water-stop system for Hongkong-Zhuhai-Macau Bridge temporary casting yard for tunnel elements in Guishan. The water-stop bound is mainly composed of Anti-seepage processed undisturbed rock and caisson gravity dam. The key design of water-stop system includes the Anti-seepage treatment between caisson gravity dam and rock foundation,the joint between caisson gravity dam and undisturbed rock,and the treatment to undisturbed rocks. The mainly anti-seepage treatment is grouting combination with embedded Z9-30 rubber water-stop and casting plan concrete,etc.
