摘　　要：深基坑作业一体化装置是针对深基坑作业而专门设计的新型机械,能够有效提高深基坑作业的安全可靠性,但是尚无相应的计价标准。文章通过分析深基坑作业一体化装置的结构特点、机械作业流程和机械功能,结合施工机械台班单价构成费用组成成分、计算方法以及定额水平测算原则,测定了深基坑作业一体化装置机械台班消耗量,取定消耗量单价,进而确定了机械台班基础数据,完成了机械台班费用定额测算,经过与常规施工方案下挖空基础人工挖方定额差异分析,提出了挖孔基础人工挖方采用深基坑作业一体化装置施工作业时定额调整建议,并选取某330kV工程,通过对施工机械台班费用水平是否满足使用寿命年限内正好收回其成本进行分析,验证了机械台班费用水平的合理性。The integrated device for deep foundation pit operation is a new type of machinery specially designed for deep foundation pit operation,which can effectively improve the safety and reliability of deep foundation pit operation,but there is no corresponding pricing standard.By analyzing the structural characteristics,mechanical operation process and mechanical function of the integrated device for deep foundation pit operation,combined with the unit price composition,cost composition,calculation method and quota level calculation principle of the construction machinery shift,this paper determines the consumption of the mechanical shift of the integrated device for deep foundation pit operation,takes the unit price of the consumption,and then determines the basic data of the mechanical shift,the calculation of the cost quota of mechanical shift is completed.Through the analysis of the difference between the manual excavation quota of excavated foundation and that under the conventional construction scheme,the quota adjustment proposal for the manual excavation of excavated foundation using the integrated device of deep foundation pit operation is put forward,and a 330kV project is selected.Through the analysis of whether the cost level of construction machinery shift can just recover its cost within the service life,the rationality of the cost level of machinery shift is verified.
