| 摘 要： | 广州合景大厦5层地下室，基坑开挖深度21．2m，采用互嵌密排人工挖孔桩连成整体。在做基坑围护的同时兼做地下室的围护结构，可利用自身水平结构作支撑。与机械成型的地下连续墙相比，工艺简单，在造价、工期、质量控制和文明施工方面更具优越性。

| Abstract: | During construction of the 5-storey basement in Guangzhou Hejing High-Rise Building project, the excavation depth of foundation pit is 21.2m, and mutually-embedded and closely-lined manual hole digging piles are connected mutually into a whole. During construction of enclosure structure in the foundation pit, enclosur~ structure in basement is built simuhaneously, and its horizontal structure can be used as support. Compared with mechanically-formed continuous diaphragm wall, this construction method is advantageous in process, cost, construction period, quality control and civilization construction. |
