摘要:
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 combined the rubber and resin together at a combined nozzle for spraying.

The disclosure concerns a modular liquid collection system for use on the roadbed of a railroad, particularly at fueling stations. The modules are arranged end-to-end along the track, and are composed of precast components made of reinforced concrete or foamed plastic. In the most complete form, each module includes a central basin which rests on the ties between the rails, and a pair of side basins which rest on the ties at the outboard sides of the rails and which are formed with integral curbs. The basins have liquid-receiving surfaces which are pitched in both the transverse and longitudinal directions and have centrally located drain openings which overlie a transverse drain trough. The basins of the end modules of a series are equipped with removable end curbs.

A protective coating system for a railway structure having a waterproof membrane and a ballast mat. The waterproof membrane is disposed on the railway structure. The ballast mat further has a ballast protection coating and a sealing layer. The ballast protection coating is a rubber compound and is disposed on the waterproof membrane. The sealing layer is disposed on the ballast protection layer.
摘要:
A method for waterproofing of bridges (1) and similar structures aimed at railway traffic is described, the structures comprising an arch or deck structure, on which there is placed a ballast (M) of gravel or crushed stone (2) upon which the tracks (6) extend between the two ends of the bridge (1). The waterproofing is obtained first by the removal of the tracks (6) and a reduced layer (S) of gravel or crushed stone (2), leaving in place the remaining part of gravel or crushed stone (2), and then by laying one or more sheets (10) of cured rubber on the remaining part of gravel or crushed stone (2). The thickness of the rubber is such as to be sufficiently resistant to perforation by the gravel or crushed stone (2), which is subsequently placed thereon to complete the ballast, Finally, the previously removed tracks (6) are set in place again. According to the method, a joint is made between the sheets (10) by means of a connection of mechanical type, with a positive locking shape fit, or a chemical bond using a suitable adhesive.

The invention relates to a vibration damping system, which comprises an anti-vibration plate in the form of a plate having a first and a second major surface, wherein the first major surface may preferably be covered with a layer of surfactant-free geotextile. The anti-vibration plate comprises one or more layers, preferably a top layer and one or more bottom layers. Furthermore, it is essential that the anti-vibration plate is preferably obtainable by a method comprising the step of subjecting an area of the opposite surfaces of the plate to a compression treatment in one or more steps, which compression treatment is sufficient to reduce the static and/or the dynamic stiffness of the plate compared to the static and/or dynamic stiffness prior to the compression. The invention also relates to the method of applying a vibration damping system and the use of a vibration damping system.
摘要:
A containment reservoir for a liquid, such as petroleum oil, comprising, a walled ground containment space or pit, opening upwardly, with the space containing a liquid impervious flexible liner generally following the contour of the space, and with the liner comprising a layer of pervious fabric material having on at least one of its sides a layer of liquid impervious material, such as rubber, the liner being operable to prevent escape of liquid through the liner from the containment space; means are provided coacting with the liner covered containment space for removing liquid from the reservoir. A covering layer of pervious fabric material filters anything, including liquid, passing into the reservoir. A method of forming the reservoir from predetermined width strips of liner stock, and a method of retaining and salvaging oil spilled along a railroad track environment is also disclosed.

摘要:
An infrastructure for railway tracks with continuous elastic support has two rails forming the track supported via elastic intermediate layers with their lateral limiting surfaces located underneath the rail head against the inner lateral limiting surfaces of a frame consisting of two frame halves and underneath each rail a longitudinal plate consisting of concrete. One of the frame halves rests against a first lateral wall of a trough while the other frame half rests via a wedge against the second lateral wall of the trough.
