石方工程是水利水电建筑工程施工的重要环节,它包括石方明挖、洞挖、运输等内容,其中某些定额子目还与砌石、灌浆、人工砂石料等工程有着密切的联系。因此,把握好石方工程预算定额的计算原则,是施工效率信息反映的需要,也是相关工程活劳动与物化劳动量化指标相互检验的需要,还是服务于水电建筑市场的需要。其就是要寻求其施工过程中不同层面上的人工工时、材料、施工机械等指标消耗之间的规律性。
Stonework is an important part of the construction of water conservancy and hydropower construction. It includes excavation, excavation and transportation of stonework, some of which are closely related to masonry, grouting and artificial gravel materials. Therefore, grasping the principle of calculating the budget quota of Shifang project is the need reflected by the information of construction efficiency, and also the need of checking each other between quantitative indicators of living labor and materialized labor, or serving the construction market of hydropower. Its purpose is to seek the regularity between the consumption of man-hours, materials and construction machinery at different levels in the construction process.
