预应力渡槽混凝土单元工程施工质量评定标准研究

Study on Construction Quality Evaluation Standard of Prestressed Aqueduct Concrete Unit Engineering

为适应大跨度小截面预应力渡槽造槽机施工新工法,依据《水利水电工程施工检验与评定规程》(SL176-2007)等规程、规范与标准以及普溪河渡槽设计及施工特点,研究制定了普溪河渡槽槽身混凝土单元工程施工质量评定标准。应用实践表明,该标准对施工质量的检验项目和检验标准以及验收评定条件和程序等进行了规定,适合于普溪河渡槽的施工特点,并可在类似工程中推广应用。

In order to adapt to the new construction method of prestressed aqueduct making machine with large span and small section,according to the regulations,codes and standards such as Inspection and Evaluation Regulations for Construction of Water Resources and Hydropower Engineering(SL176-2007)and the design and construction characteristics of the aqueduct of Puxi River,the construction quality evaluation standard of concrete unit engineering of the aqueduct body of Puxi River was studied and formulated.The application practice shows that the standard stipulates the inspection items,inspection standards,acceptance and evaluation conditions and procedures of construction quality,and is suitable for the construction characteristics of Puxi River aqueduct,and can be applied in similar projects.
