Provision for the anti-corrosion treatment of cables

The invention relates to a device for the anti-corrosion treatment of cables, through which the application and / or introduction a plastic «a plastic-containing mixture and / or a useful corrosion compound or an anti-corrosion agent on or in cables. According to the invention, cables, in particular those for suspension bridges, cable-stayed bridges, Bracing and the like, so also preferably cables of all types that are already in use by means of the device subsequently provided with a protection that prevents corrosion. The inventive device encloses the Cable sheath in whole or in part and has insertion devices through which plastic, plastic-containing mixtures and / or Corrosion protection agents or corrosion protection compounds on or around the cable or in the spaces between the individual cables, Wires, wire bundles and the like. Can be brought.

It is known, patent-locked or manufactured by other methods cables before and / or after their assembly with a to provide corrosion-preventing paint. Although this coating initially prevents corrosion, it penetrates in the course of the process moisture in the cable over time and caused by the cable

progressive corrosion inside. Neither can this this prevents a new coat of paint from being applied to the cable sheath at certain time intervals.

It has also already been proposed "a device for use «in which a container is provided for single wire coating, the container having a sorting device for the Has wires or rods of the cable. To bundle the wires or rods into a parallel wire bundle, an adjustable and driven pair of rollers calibrated according to the parallel wire bundle or a cable loop provided with a traction mechanism is used. With the help of this device is cable with a corresponding corrosion-inhibiting protection. For the corrosion protection treatment of cables that have already been used this device can only be used with great difficulty.

The aim and object of the present invention is therefore to create a device with the aid of which cables that are already in use can be retrospectively and without dismantling the cables can be provided with a corrosion-preventing permanent protection. According to the invention, this takes place in that a device is used »which completely or partially encloses the cable jacket and has insertion devices» the plastics »plastic-containing mixtures and / or anti-corrosion agents or anti-corrosion compounds on or around the cable or into the spaces between the individual cables, wires, wire bundles and the like *.

According to one embodiment, the device consists of one reusable formwork body, the la distance from each other, Feeding devices, preferably offset from one another plastic-containing mixtures and / or the Wet agents or agents can be introduced into the cable, preferably in the space between the wires, partial cables, wire bundles and the like. This formwork body can consist of metal, plastic or other suitable materials. Her reusable formwork body can be composed for example of two ie cross-section semi-circular formwork bodies "by per se known fasteners such as hinges" screw "buckles, cords and the like can be held together.. In addition, sealing flanges and the like can be used on the Y * "* * ^ Tw hw ^ g ^ ffrTLl *? ** of the reusable formwork bodies. According to one embodiment, the reusable formwork body sits firmly on the cable and forms the entire cable jacket or partially in the form of a coating that prevents or prevents the passage of air and / or air. Due to the attachment devices attached to the reusable formwork body, e.g. funnels or nozzle-like egg injection devices, plastics, mixtures containing plastics, preferably corrosion protection agents, can get into the cable preferentially »Be introduced wisely in the space between the wires, partial cables, wire bundles, etc. The sinbringvorriehtung can also be in combination with a device that enables a certain amount of space within the reusable formwork body

The slnsnrlts, SindrSek and / or SLnsaugvorrichtung used in combination with the injection device can be used in different ways and, in some cases, have the shape of a syringe, suction device and the like. These gate directions can advantageously be equipped with a ball pressure valve «

According to a particularly advantageous embodiment, the Door direction from a lost formwork, which the cable sheath

wholly or partially in Ροπή one of the moisture and / or Surrounds the air passage preventing or reducing sheathing. In this permanent formwork, it is advisable to insert, preferably press-in, push-in and / or suction devices attached at a distance from one another. This insertion, press-in, Push-in and / or suction devices can subsequently be removed or cut off, broken off and the like. without causing any substantial material damage.

In the accompanying drawings, some exemplary embodiments are shown schematically, in FIG. 1 a device consisting of a permanent formwork is shown schematically. The cable surrounding the device is shown schematically under (1). In this exemplary embodiment, the lost formwork consists of a cable jacket wholly or partially in the form of a jacket that prevents the passage of moisture and / or air. In the lost formwork, insertion, pressing, pressing and / or suction devices are attached at a distance from one another under (5). Dieje transferor devices (5) are enclosed in the lower part of DER permanent shuttering so that during the pressing of material, such as plastic mixtures, corrosion protection compositions may occur no plastic at this point to the outside.

In Fig. 2, a reusable formwork body is shown, which also at a distance from each other, preferably offset from each other arranged insertion devices, funnels (5) * nozzles and the like. Or plug-in or insertable syringes and the like. (3)

owns. The plastics, plastics-containing mixtures, anti-corrosion agents and / or anti-corrosion compounds are also introduced into the cable through these insertion devices, expediently introduced under pressure and / or negative pressure. The reusable formwork body, which is made from, for example two formwork halves (8) can consist of SCxir ">> en, Clamps, clamps, tapes and the like. Closed, with additional Sealing flanges can be used.
