珠澳口岸人工岛水泥搅拌桩施工质量控制

Cement mixing pile construction quality control of the Zhuhai-Macao Port artificial island

结合港珠澳大桥珠澳口岸人工岛西北护岸水泥搅拌桩施工,简述水泥搅拌桩施工质量控制要点和方法。水泥搅拌桩施工质量控制的关键为水泥搅拌机型的选择、水泥品牌的选用、水泥掺入量和每延米用量的选配、桩位、桩径和垂直度的控制、施工参数的确定。

Combined with the cement mixing pile construction of the northwest revetment of the artificial island in the HZMB, this paper describes the construction quality control points and methods of cement mixing piles. The key points for the quality control are the selection of cement mixer types, the selection of cement brands, the cement content, the matching amount per linear meter, the control of pile location, pile diameter and the vertical degree, construction parameters , and the determination of construction parameters.
