Construction method for cable group pipes to penetrate through waterproof concrete wallboard
The invention discloses a construction method for a cable group pipe to penetrate through a waterproof concrete wallboard, which comprises the following steps: reserving a hole during primary structure construction, designing the inner edge of the hole to be Z-shaped, enabling the size of the upstream face of the hole to be equal to the outer wrapping size of a rear embedded part minus 40mm * 2mm, enabling the size of the inner side of the upstream face of the hole to be equal to the outer wrapping size of the rear embedded part plus 40mm * 2mm, enabling the step height to be 80mm, and enabling the step height to be 80mm; the L5 * 4mm angle steel frame at the corner part of the step is used for welding and fixing with a rear sleeve piece; a linear cutting technology is adopted for factory processing of the embedded sleeve, and the sleeve and the water stop steel plate are in double-sided full-length welding connection; the rear embedded part is installed from the inner side and connected with the pre-embedded angle steel frame in a welded mode, and the water swelling strip is installed at the combination position of the upstream face on the outer side; and a calcium silicate board with the thickness of 6mm is used as a template for secondary molding. The method is easy and convenient to construct, low in manufacturing cost, reliable in waterproof performance, attractive in surface and suitable for construction of the embedded pipe centralized arrangement position in the concrete wall plate with the thickness larger than or equal to 250 mm in structural construction.
本发明公开了一种电缆群管穿防水混凝土墙板施工方法，一次结构施工时预留洞口，洞口内边设计为“Z”型，洞口迎水面尺寸＝后置埋件外包尺寸－40mm×2mm，内侧被水面洞口尺寸＝后置埋件外包尺寸+40mm×2mm，台阶高度80mm，台阶转角部位L5×4mm角钢框用于与后置套管件的焊接固定；预埋套管工厂化加工采用线切割技术，套管与止水钢板双面满焊连接；后置埋件从内侧安装，与预埋角钢框焊接连接，外侧迎水面结合部位安装遇水膨胀止水条；二次制模采用6mm厚硅酸钙板作为模板。本发明施工简便、造价经济、防水性能可靠、表面美观，适用于结构施工中厚度≧250mm的混凝土墙板中预埋管集中布置部位的施工。
