摘要
施工 3～4．4m空心桩，需要预制空心桩节和护筒、搭建水上平台，进而介绍了钻孔施工、桩节组拼以及压浆等工艺。与实心桩相比，空心桩显示了独特的优越性。
It is necessary to prefabricate hollow pile sections and the conductor casing for the construction of 3 to 4. 4m hollow piles. The drilling process, pile section assembly and grout injection are described. The hollow pile exhibits unque adventage over the solid one.
