某修造船厂邻海极不均匀岩石回填地层深基坑止水工程研究

A STUDY ON THE WATER SEALING ENGINEERING OF DEEP FOUNDATION PIT WITH UNEVEN ROCK BACKFILLING STRATA IN A SHIPYARD’S COASTAL AREA

结合某海外修造船厂升级改造工程某设备深基坑群止水工程实例,探讨了在海外工程中充分利用各类条件实现深基坑止水施工的方法,并最终确定通过水下作业设置优化后的挡水墙有效控制涌水量,形成封闭的隔水体系,并辅以有效排水措施完成深基坑止水工程,对海外相关深基坑止水工程施工具有一定参考和借鉴意义。

Based on the upgrading and renovation project of an overseas shipyard and an example of a deep foundation pit group water stop project,this paper explores the methods of fully utilizing various conditions to achieve deep foundation pit water stop construction in overseas projects.Finally,it is determined that the optimized water stop wall through underwater operation can effectively control the water inflow,form a closed water stop system,and complete the deep foundation pit water stop project with effective drainage measures,Which has certain reference and reference significance for the construction of overseas deep foundation pit water stop projects.
