A cut and cover method of constructing grade separation structures includes partially burying precast substructure elements with associated trench boxes under live traffic. Once the precast substructure elements are buried, the substructure is completed and the bridge span is installed. Other methods include installing precast superstructure elements with a formwork system and forming a bridge substructure and excavating underneath the superstructure once the superstructure is formed.

A method of monitoring tube integrity of a high-speed transportation system. The high-speed transportation system includes at least one tube structure having at least one track, at least one capsule configured for travel through the at least one tube structure between a plurality of stations, a propulsion system adapted to propel the at least one capsule through the structure, and a levitation system adapted to levitate the capsule within the structure. The tube structure is maintained as a low-pressure environment. The method includes directing a vehicle having at least one sensor along a tube path; and detecting a plume of air leaked from the low-pressure environment using the at least one sensor.

A method and apparatus for coating transportation components such as a bridge deck with a coating. The coating includes a sealant and rubber mixed with a resin and a foaming agent. The apparatus includes a hopper for the rubber, a impingement gun for the resin and a gun assembly that combines the rubber and resin together at a combined nozzle for spraying.

The invention relates to an overhead guided-transport track span having a U-shaped cross section, the two arms of which form lateral walls (4, 5) of said track, and the central region of which, connecting the two arms, forms a load-bearing slab (6) of said track, characterised in that said load-bearing slab (6) comprises at least one groove (10, 11) that is provided in said slab longitudinally along said span and is designed to be able to receive a running support (12, 13) of a guided-transport vehicle intended to travel on said track.

The invention is a system and method for repairing, improving, and stabilizing subgrade and subsoil/natural ground layers of a rail bed generally consisting of softer soils. One embodiment includes a method of installing subsurface inclusions and ballast fills comprising injected slurry mixtures of stabilizing material such as cement grout mixed with in situ soil. Another embodiment includes a system of installed ground inclusions and ballast fills. Another embodiment includes an integrated system of equipment for emplacing the system of inclusions and ballast fills.

The invention relates to transport and logistics systems of large cities, and may be used in construction of cities with population of over five hundred thousand people. The technical result of the proposed solution is to optimize the urban transport and logistics system, eliminate traffic congestions and ensure rapid movement to any point in the city. The urban transport and logistics system includes the first ground level for road and rail freight transport, the second level of pipeline and technical communications, the third level of passenger transport, the fourth pedestrian level, each level being located one above the other, and they are connected with each other and with residential and non-residential buildings by vertical staircase-elevator modules.
