1泥浆在成孔过程中泥浆的作用:①护壁;②作为载体在循环中将冲(钻)出残渣从孔底带到桩孔外部。泥浆的护壁及循环作用是施工水下灌注桩的关键及该工法的根本原理所在,对泥浆质量的控制应科学、立足于其基本原理,贯穿钻进成孔及灌注成桩全过程。
1 Slurry mud in the process of forming the role of the hole: ① retaining wall; ② as a carrier in the cycle will be washed (drill) out of the residue from the hole to the outside of the pile hole. Mud wall and the role of circulation is the key to the construction of underwater piles and the fundamental principle of the method, the quality control of the mud should be scientific, based on its basic principles, drilling through into the hole and perfusion into the pile the whole process.
