| Key technologies of construction of middle columns by Top-down method in huge metro station foundation pit |
| 摘要 |
| 針對(duì)蓋挖逆作地鐵車站的中間樁施工技術(shù)難題，運(yùn)用理論分析并結(jié)合現(xiàn)場(chǎng)實(shí)踐，提出了樁基施工、定位器安裝、鋼管柱吊裝和固定、鋼管柱內(nèi)混凝土灌筑以及管外填砂等施工技術(shù)和工藝。實(shí)踐表明，按研究出的工法進(jìn)行施工時(shí)，鋼管立柱中心線與基礎(chǔ)中心線、立柱頂面不平整度等施工偏差 |
