METHOD FOR JOINING COASTAL AND RIVER PARTS OF FLOATING UNIFIED RAILWAY RIBBON BRIDGE MLZH-VF-VT Russian patent published in 2021 - IPC E01D15/14 

FIELD: military bridge construction.

SUBSTANCE: invention relates to the field of military bridge construction and can be used in the design, manufacture, building and operation of demountable floating railway bridges. The method of joining the coastal and river parts of the MLZH-VF-VT floating unified railway ribbon bridge is characterized by the fact that the river part at the junctions to the transitional parts of the bridge is performed with expanded inventory pontoons, the span structures of the transitional and coastal parts of the bridge are welded metal with main I-beams, to the upper booms of which track rails and road passage elements are attached. Supporting hinged beams and compensating hinged beams are attached to the ends of the spans of the transitional parts, by means of which the spans of the transitional parts are supported on the river part of the bridge and on the flat lifting supports of the coastal parts. Each lifting support is made with a three-dimensional rigid strut of two lattice beams spaced on the sides of the support struts, which are attached to the lower part of the struts through brackets with the possibility of providing a clear distance between the lattice beams to place the crossbar in the lower position inside the rigid strut and reduce the construction height of the roadway on the support, allowing transportation of the support on the mounting plate from the assembly site, its installation and operation at depths corresponding to and exceeding the minimum depths of building and operation of the river part of the bridge.

EFFECT: simplifying the design of the butt joint of the coastal and river parts of the floating bridge.
