摘要:
A modular supporting structure for dismountably supporting a section of railway track (12) while work is in progress below the tracks; comprising at least one adjusting assembly (18) configured so that it can be disassembled from bracing rails (16, 161, 162), which assembly comprises a first adjustable rod cylinder (32) disposed crosswise to bracing rails (161, 162) and a second adjustable rod cylinder (33) and a third adjustable rod cylinder (34) to adjust the height of modular supporting structure (11) to the plane of the running surface in the working position of modular supporting structure (11).

A pit cover 1 comprises a substantially rectangular tabular top plate 3, ribs provided on a reverse surface side of the top plate 3, handholds 5 provided on both edges in a width direction, and the like. On a reverse surface 1b side of the pit cover 1, a plurality of width direction ribs 7a is formed in the width direction of the pit cover 1, and a plurality of length direction ribs 7b substantially orthogonal to the width direction ribs 7a is formed in the length direction of the pit cover 1. Assuming locations surrounded by the width direction ribs 7a and the length direction ribs 7b to be spaces, the spaces disposed on both edges in the width direction of the pit cover 1 are the spaces 11a that open to an outer side in the width direction of the pit cover 1. Specifically, the spaces 11a are formed so as to be open only to a bottom surface side and one side surface side of the pit cover 1.
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.
摘要:
The present invention relates to a junction structure (1) for supporting at least one rail (2) in the region of a joint (3) of a railway bridge (4) and a railway bridge (4) which is constructed with such a junction structure (1). The latter has at least two displaceably mounted cross beams (5, 6, 7), at least one joint sleeper (8) which is attached to the cross beams (5, 6, 7) and has the purpose of supporting the at least one rail (2) in the region of the joint (3), and at least one control device (14) for orienting the position of the joint sleeper (8) in the junction structure (1), wherein the at least one joint sleeper (8) has a rail attachment (13) with which the joint sleeper (8) can be displaceably attached to the rail (2). According to the invention, the cross beams (5, 6, 7) and the control device (14) are arranged underneath the at least one joint sleeper (8).
