永久钢管桩深水基础补充定额

SUPPLEMENTARY QUOTA OF PERMANENT STEEL PIPE PILE DEEP WATER FOUNDATION

深水基础永久钢管桩在跨江大桥工程中已被广泛应用,以江苏及其他国内跨江、跨海工程为依托,根据施工现场实测及相关技术资料,在收集施工图纸、施工技术方案、现场施工工序、机械型号种类等原始资料基础上进行永久钢管桩预算补充定额的编制和研究。鉴于钢管桩根据桩长和桩径可形成较多定额子目,故以永久钢管桩(桩径1.8 m以内、桩长80 m以内)为例,对永久钢管桩补充定额的工艺模型建立、基础数据收集、补充定额的编制、大型船机台班单价的确定、幅度差研究等具体内容的研究总结,为今后永久钢管桩基础造价成本管理提供参考依据,为今后"四新工程"的定额编制提供范例。

Deep water foundation permanent steel pipe pile has been widely used in river crossing bridge engineering,the article relies on Jiangsu and other domestic cross-river and cross-sea projects,according to actual construction site measurements and related technical data,based on collecting construction drawings,construction technical plans,site construction procedures,mechanical models and other original data, and carries out preparation and research of supplementary budget quotas of permanent steel pipe piles. In view of the fact that steel pipe piles can form more quota sub-items according to pile length and pile diameter, permanent steel pipe piles(pile diameter within 1.8 m and pile length within 80 m)are taken as an example to establish a process model for supplementing the quota for permanent steel pipe piles, collect basic data, preparing supplementary quotas,determining of the unit price of large ship machines and study the range difference,etc.,providing a reference basis for cost management of the permanent steel pipe pile foundation in the future and examples for establishment of quotas for the future "Four New Projects".
