升浆混凝土骨料抛填及坞墙基础施工

Placing of Aggregate Fill for Prepacked Aggregate Concrete and Construction of Foundation for Dock Walls

船坞抛填工程均为水下隐蔽工程，施工工序繁多，质量控制难度大，尤其是对坞墙基础必须严格控制沉降和位移，防止坞墙接缝开裂漏水。由于采取了合理的施工工艺和技术措施，保证了船坞抛填工程按期顺利完成。

Aggregate fill placed for dock foundation is underwater concealed work,it is therefore difficult to control the quality of the work as the sequence and process of construction are much complicated and various, especially the foundation for dock walls, which must be so erected to strictly control the settlement and displacement and to avoid the development of cracking in the wall joints causing water leaking. Thanks to the rational and appropriate technology and technical measures which had been taken during the construction,the placing of aggregate fill was successfully completed as scheduled.
