Construction method for crossing existing municipal drainage pipe ditch
The invention relates to municipal project pipeline construction, in particular to a construction method for crossing an existing municipal drainage pipe ditch. The method comprises the steps that the intersection length of a foundation pit needing to be excavated and an existing municipal drainage pipe ditch is measured, and a spiral welded pipe with the matched size is measured; two steel reinforcement frameworks are welded to the two ends of the spiral welding pipe respectively, and scale meshes are installed on the outer sides of the steel reinforcement frameworks to serve as formworks; sludge at the corresponding position of a steel reinforcement framework in the existing municipal drainage pipe ditch is cleaned, and the spiral welded pipe is hoisted to the corresponding position in the existing municipal drainage pipe ditch; concrete is poured into the reinforcement cage on the two sides of the spiral welded pipe to block the existing municipal drainage pipe ditch; and breaking the existing municipal drainage pipe ditch between the two concrete plugs. The spiral welded pipe is used for crossing, the steel reinforcement framework is used for pouring concrete for blocking, crossing construction is achieved, the construction method is safe and convenient, time and labor are saved, the construction speed is high, the construction efficiency is improved, and the construction cost is reduced.
本发明涉及市政项目管线施工，具体是一种跨越既有市政排水管沟的施工方法。步骤是：量取需要开挖的基坑与既有市政排水管沟的相交长度，量取尺寸相适应的螺旋焊管；在螺旋焊管的两端分别焊接两片钢筋骨架，在钢筋骨架的外侧安装鱼鳞网片作为模板；清理既有市政排水管沟内钢筋骨架对应位置的淤泥，将螺旋焊管吊装至既有市政排水管沟内对应位置；在螺旋焊管两侧的钢筋骨架内浇筑混凝土对既有市政排水管沟进行封堵；破除两处混凝土封堵之间位置的既有市政排水管沟。本发明通过使用螺旋焊管进行跨越并使用钢筋骨架浇筑混凝土进行封堵，实现跨越施工，施工方法安全便捷，省时省力，施工速度快，提高施工效率，降低施工成本。
