南水北调中线淅川段工程格子河两联6孔排洪涵洞混凝土施工,共计84个仓位,从2012年3月15日开始施工,6月15日完成,历时3个月,共浇筑混凝土为2.88万m3,钢筋2785 t。文章根据格子河排洪涵洞施工特点,混凝土垂直入仓方式采用BLJ600-40B履带式混凝土布料机和混凝土泵车,因此在土方开挖时,将一级马道的宽度调整为10 m,以利于履带式混凝土输送布料机有足够的作业空间。该项目强度大,进度快,按期完成施工任务,对多联箱涵混凝土施工类似工程有借鉴意义。
Construction of the mid-south section of the South-to-North Water Diversion Project of the Xichuan section of the Gezihe River with 6 holes drainage culverts for a total of 84 warehouses started from March 15, 2012 and completed on June 15 and lasted for 3 months with a total of 28,800 m3 of concrete , Steel 2785 t. According to the construction characteristics of the grid river drainage culverts, the concrete vertical warehousing adopts BLJ600-40B crawler concrete distributor and concrete pump truck, so the width of the first-class horse road is adjusted to 10 m when earthwork excavation, in order to facilitate the track Concrete conveying fabric machine has enough work space. The project is strong, fast progress, completion of construction tasks on schedule, the multi-joint culvert concrete construction similar projects have reference.
