摘　　要：为保证超大面积上盖地铁停车场10000多根不同桩径、桩长的钻孔灌注桩施工质量和施工进度,研发了一种新型的灌注桩孔底沉渣厚度测量工具,并采用半自动滚笼机加工箍筋以及采用泥浆分离器处理钻孔灌注桩废泥浆。实践证明,上述技术措施的应用,加快了施工进度,确保了施工质量,取得了良好的社会和经济效益,可为类似工程施工提供借鉴。To ensure the construction quality and progress of more than 10000 bored piles with different pile diameters and lengths in a super large area of subway upper cover parking lot,a new tool for measuring bottom sediment thickness of bored pile is developed.The semi-automatic cage rolling machine is used to process stirrups and the mud separator is used to treat the waste slurry of bored piles.The practice proves that the application of these technical measures can speed up the construction progress,ensure the construction quality,obtain good social and economic benefits,and can provide reference for the construction of similar projects.
