Duct bank array installation and encapsulation construction method
The invention discloses a duct bank array installation and encapsulation construction method. After cushion concrete is constructed, a cushion layer is used as an operation platform to install first duct banks and second duct banks into two duct bank arrays through matched first middle pipe pillows, second middle pipe pillows, first end pipe pillows, second end pipe pillows, first casing pipes, second casing pipes, distribution reinforcing bars, vertical reinforcing bars and anti-floating reinforcing bars, the two duct bank arrays are effectively connected into a whole, then downward-pressingreinforcing bars, side formworks and end formworks are combined, and encapsulating concrete is continuously poured in a layered mode after concealed project acceptance. The construction method is suitable for installation of power cable MPP duct banks of different specifications in open cut construction on most urban roads, and has the advantages of being low in manufacturing cost, high in construction speed, attractive in technology, high in compressive strength, high in adaptability and the like.
一种排管阵列安装及包封施工方法，在施作垫层混凝土后，以垫层为作业平台，将第一排管和第二排管通过与配套的第一中间管枕，第二中间管枕，第一端头管枕，第二端头管枕，第一套管，第二套管、分布配筋，竖向配筋和抗浮钢筋安装成两个排管阵列，两个排管阵列之间有效连接成一个整体，再利用下压钢筋、侧模板和端头模板组合，通过隐蔽工程验收后分层连续浇筑包封混凝土。本施工方法适用于大多数城区道路上明挖施工的不同规格的电力电缆MPP排管安装，具有造价较低、施工速度快、工艺美观、抗压强度高、适应性强等特点。
