DE19827398A1 - V-shaped cable trough channel for railway lines - Google Patents

Abstract

The V-shaped concrete cable trough channel for accommodating cables of minimal diameter for overriding use in railway installations is described. The downwards V-shape and the minimal dimensions allow the cabling in a groove made with an auxiliary device without shaft work to make a special cable bed. The cable trough channel has a minimal space requirement. Its inside lids (2) run slightly conically downwards, whereby a rigid seat is improved and a sealing band can be done without. Its inside lids as a result of the minimal lid thickness turn out thinner, easier, and more material saving. The connecting points of the lower parts are laid in a sealing and adjusting plastic sleeve (4) which is open upwards.

Description

DBAG railway lines, other railway operators and industrial railway lines are mainly used with conventional concrete cable trough systems Laying of external cables (signal, telecommunication, control and power cables) fitted.

There are (approximately 95%) concrete trough channels of different sizes DBAG specification (e.g. according to rule drawing S4201.01.5; S4201.03.3; S4201.05.2 of the former Federal Central Railway Office). All of these cable trough channels are difficult to handle due to their dimensions and require complex Civil engineering input. This is known to result in a very high level Expense. Also on routes on which only the laying of 1-2 thin cables - such as. B. Optical fiber cable provided by the Arcor or pre-signal cable - must be Solution or an even more complex burial.

The invention shown in claim 1 is based on the idea to create a smaller and more manageable concrete cable duct that with minimal civil engineering work is feasible.

The problem is - according to patent claim 1 - due to the downward tapered V-shape as well as the significantly smaller dimensions and thus possible installation in an easy to manufacture furrow solved.

Instead of a laying bed with gravel to be produced by means of a shaft, a special "trough channel plow" tool is used to produce the above-mentioned laying groove. The soil can no longer be excavated and gravel can no longer be brought in - the existing soil is only displaced and the V-channel lower section [ 1 ] is inserted into the plowed furrow so that the upper edge is flush with the surface of the earth. The installation technology thus possible results in a cheaper installation effort; In addition to shorter construction times, this also leads to a lower installation price.

Further advantages are presented in claim 2.

The smaller dimensions mean that less space is required. Because of this and again because of its shape, it can also be used in confined areas

• - So even where the smallest cable trough channel size has not yet been used was applicable.

The inner covers [ 2 ] are - due to the significantly smaller width - much thinner and lighter. The conical shape enables a comparatively tight seal even without a sealing tape.

The V-concrete duct has a lower weight due to its smaller dimensions, that leads u. a. for better handling than with all conventional concrete Trough channel systems.

Another essential feature is a plastic sleeve [ 4 ] which is open at the top and into which the lower parts [ 1 ] are connected and which adjusts and seals them to the outside.

If necessary, the V-cable trough channel can be fixed using ground anchors - pointed flat iron [ 5 ].

The invention is described in the following illustrations:

Figure 1 to scale sectional view,

Figure 2 perspective view (without scale)

Figure 3 perspective view with connecting sleeve

Picture 4 - like picture 3 - trough lower parts pushed together.

Description based on picture 2

The following lower part is inserted with the upper fold [ 6 ] in the lower fold [ 7 ] of the following part. However, the lower parts can only be laid in one direction.

After completion of the route from the V-channel lower parts, the cables are inserted [ 3 ]. Finally, the 0.33 m long sealing cover [ 2 ] is inserted.

Possible dimensions of the V-channel lower part:
I: 1 m (possibly 0.5 m); b: approx. 170 mm; h: approx. 160 mm.

The invention is illustrated in the accompanying illustrations:

Claims (2)

1. The V-concrete cable trough channel for receiving cables of small diameter for priority use in railway systems is characterized in that the downward tapering shape and the small dimensions, the laying in a furrow made with a tool without shaft work to produce a special laying bed allowed. 2. The V-concrete cable trough channel according to claim 1 is characterized in that

• 2.1 that it has a small footprint,
• 2.2 that its inner cover [ 2 ] is slightly conical downwards; thus a firm seat is promoted u. there is no need for a sealing tape,
• 2.3 that its internal sealing covers [ 2 ] are thinner, lighter and less material-consuming due to the small cover,
• 2.4 that the connection points of the lower parts are placed in a sealing and adjusting plastic sleeve [ 4 ] which is open at the top,
• 2.5 that the lower parts can be better fixed in the floor using pointed flat irons [ 5 ] (hammered in parallel to the side walls).
