软体排浅滩陡坡对铺施工工艺

在长江南京以下12. 5 m深水航道建设工程一期工程通州沙Ⅱ标段实施中,存在有大范围高滩排和深水排过渡段的软体排铺设。针对如何实现浅滩陡坡软体排一次性铺设的问题,进行船舶选型和施工方法的研究和论述,采用浅滩陡坡对铺施工工艺,实现了高滩排和深水排过渡段的一次性铺设,避免了软体排分幅搭接可能导致的质量问题,能够有效地保证施工质量,为类似工程提供参考和借鉴。

Construction technology of soft mattress by abutting joint laying for soft shoal and steep slope

In second section of the first phase of the construction of the 12.5 m deep water channel construction project in the Yangtze River below Nanjing,there is a wide range of soft mattress laying in transition between the high beach and deep water.Aiming at the problem of how to realize the one-time laying of the steep slope section of the shoal,we study and discuss the ship selection and construction method,and apply the construction technology of soft mattress by abutting joint laying for soft shoal and steep slope.The technology achieves the one-time laying of the high shoal and the deep water transition section,avoids the possible quality problems which may lead to the split amplitude lap joint.It can effectively guarantee the quality of the construction,and can provide reference for the similar projects.
