Problems solved by technology

At present, the only railway pontoon bridge in my country is the 67-type railway pontoon bridge. The maximum length of the pontoon bridge is 700m, but the river needs to be closed to navigation during the use period, which cannot be used for rivers with navigation needs

Abstract

The invention discloses a navigable elevated railway pontoon bridge. The navigable elevated railway pontoon bridge is arranged between two shores of the water surface from the shore on one side to the shore on the other side, sequentially comprises a fixed trestle (1), a movable trestle (2), a side hole floating bridge (3), an in-river floating bridge (4), a side hole floating bridge (3), a movable trestle (2) and a fixed trestle (1); each fixed trestle (1) is fixed to one shore and enables a railway on the shore and the movable trestle to be connected (2); each movable trestle (2) is of a lifting structure and enables the fixed trestle (1) and the side hole floating bridge to be connected (3); the in-river floating bridge (4) comprises multiple sections of standard floating joints (41), wherein the standard joints (41) adjacent to deep-water-level positions each use at least one section of navigable floating joint (42); and the lower space below the navigable floating joints (42) forms a VI-level navigation channel allowing small ships to pass through. The navigable elevated railway pontoon bridge is of a railway floating bridge structure, trains can pass on the bridge, ships can navigate below the bridge, the navigable elevated railway pontoon bridge can be disassembled, assembled and used repeatedly, and is mainly used for broad rivers with large water flow, navigation capacity and high riverbanks.

Description

technical field [0001] The invention relates to the technical fields of mechanical structures and traffic emergency engineering, in particular to a navigable elevated railway pontoon bridge. Background technique [0002] The pontoon bridge is an ancient bridge crossing facility, which replaces the fixed foundation with a floating foundation, and the assembly speed is faster, so it occupies an extremely important position in emergency engineering, especially for rivers with wide rivers and deep water. Compared with permanent bridges, pontoon bridges have better economy, shorter construction period, and do not occupy the bridge site permanently. Floating bridges can be divided into railway pontoon bridges, highway pontoon bridges and pedestrian pontoon bridges according to their load bearings. Among them, road pontoon bridges and pedestrian pontoon bridges mostly adopt belt pontoon structures, and railway pontoon bridges mostly adopt longitudinal continuous beam structures. A...
