摘要
武汉地铁11号线丁~马区间明挖段围护桩与瑞景广场原有围护桩存在重叠的现象,瑞景广场原有围护桩废除施工场地狭小,距离建筑物近,施工组织、建筑物保护难度大。施工实践表明,采用全回旋钻机拔桩施工有效解决原有围护桩拔出的难题,具有提高施工功效、节约工期、施工环保和对周边建构筑影响小等优点。
There are overlaps between retaining piles in open dig section of Ding^Ma Section of Wuhan Metro Line No.11 and the original retaining piles in Ruijing Square.The original retaining piles in Ruijing Square are abolished in a narrow construction site close to the buildings and the construction organization and building protection are very difficult.The construction practice shows that it is effective to solve the pulling out problem of original retaining piles by using full rotary drill,which has the advantages of improving construction efficiency,saving construction period,environmental protection and little influence on surrounding construction.
