Method for enabling overhead trestle to underpass existing railway frame bridge to keep open shortcut
The invention discloses a method for enabling an overhead trestle to pass through an existing railway frame bridge to keep a shortcut, the existing railway frame bridge is a double-hole frame drainage culvert, and the method comprises the steps that a culvert on one side of the double-hole frame drainage culvert is constructed to serve as a traffic culvert, and the other side of the double-hole frame drainage culvert is reserved to serve as a drainage culvert; a temporary steel bridge is constructed in the traffic culvert to form a construction passage crossing a bottom plate of the existing frame culvert, the construction passage is integrally connected with passages on two sides of the double-hole frame drainage culvert to form a communicating passage, a clearance is reserved between the temporary steel bridge and the bottom of the traffic culvert, a gap is reserved between the temporary steel bridge and culvert bodies on two sides of the traffic culvert, and the temporary steel bridge is a single lane and is provided with a height and width limiting structure. According to the invention, low-clearance crossing can be realized, and the drainage smoothness in the flood season is guaranteed.
本发明公开了一种架空栈桥下穿既有铁路框架桥保通便道的方法，既有铁路框架桥为双孔框架排水涵，包括：将双孔框架排水涵的其中一侧涵洞施工作为交通涵，而另一侧保留为排水涵，交通涵内施工钢便桥形成跨越既有框架涵底板的施工通行通道，其与双孔框架排水涵两侧的通道连接为一体形成保通便道，钢便桥与交通涵底留有净空，钢便桥与交通涵的两侧涵身具有间隔，钢便桥为单车道且设置有限高限宽结构。本发明能实现低净空穿越，且保证对汛期排水顺畅性的保障。
