Description

Die Erfindung bezieht sich auf einen Stockbaum und ein Verfahren zur Erhöhung und/oder Sanierung von Beton- und Stahlvollwandmasten unter Verwendung eines solchen Stockbaums gemäß dem Oberbegriff der Patentansprüche 1 und 5.The invention relates to a tree and a method for increasing and / or rehabilitating concrete and solid steel masts using such a cane tree according to the preamble of claims 1 and 5.

Ein solches Verfahren und ein solcher Stockbaum kommen bei der Sanierung von Beton- und Stahlvollwandmasten zur Anwendung, die im Bereich ihrer Traversen beschädigt sind. Sie können jedoch auch zum Erhöhten von Beton- und Stahlvollwandmasten genutzt werden.Such a method and such a tree can be found in the rehabilitation of concrete and solid steel pylons for use damaged in the area of their trusses. However, they can also be used to elevate concrete and steel solid pylons become.

Stockbäume werden bis jetzt nur beim Neubau von Gittermasten für Freileitungen verwendet. Bei den hierfür genutzten Stockbäumen wird zwischen den kurzen Innenstockbäume und den langen Außenstockbäumen unterschieden. Um mit solchen Stockbäumen arbeiten zu können, müssen sie neigbar gehaltert werden. Die Spitzen dieser Stockbäume sind deshalb nach allen vier Seiten mit Seiten und Greifzügen beweglich verankert.Stick trees are used until now only in the construction of lattice towers for overhead lines. In the used for this tree trees is between the short inner floor trees and the long outdoor trees. To deal with such stick trees to be able to work, they have to be held tiltably. The tips of these Stick trees are therefore movable on all four sides with sides and grab trains anchored.

In der deutschen Patentanmeldung 199 15 499. 6 ist ein Betonmast beschrieben, der saniert und/oder erhöht und gleichzeitig mit neuen Traversen aus Stahl versehen werden kann. Hierbei lassen sich die Kosten für den Gerüstbau nur dann einsparen, wenn die Leiterseile während dieser Arbeiten oben auf dem Betonmast verbleiben können. Das bei der Erhöhung und/oder Sanierung abgetrennte Ende des Betonmasts mit den daran befindlichen Traversen kann nur dann abgelassen werden, wenn die Traversen hierfür gedreht bzw. ausgeschwenkt werden können. Das ist jedoch bis jetzt nicht möglich, wenn die Leiterseile oben auf dem Betonmast verbleiben, denn in diesem Fall müsste das Schwenken der Traversen noch in der Höhe erfolgen, in der das Ende abgetrennt wird bzw. der spätere Einbau der neuen Spitze erfolgt. Diese Arbeiten können nur mit einem Stockbaum ausgeführt werden. Die bis jetzt bekannten Stockbäume sind hierfür zu kurz. Die Seilanker mit denen diese Stockbäume verbunden sind behindern zudem die Sanierungsarbeiten. Andererseits sind nur Stockbäume für diese Arbeiten geeignet, weil sich nur diese zu den Masten transportieren lassen, die nicht mit einem Kran angefahren werden können. Das gleiche gilt auch für die Montage der neuen Spitze, an der die Traversen aus Stahl bereits befestigt sind.In the German patent application 199 15 499. 6 a concrete mast is described, the renovated and / or increased and at the same time be provided with new steel trusses can. Here, the costs for scaffolding can only be saved if the Ladder ropes can remain on top of the concrete mast during this work. The at the raised and / or redevelopment separated end of the concrete mast with the it located trusses can only be drained, if the trusses for this can be rotated or swung out. However, this is not possible until now the ladder ropes remain on top of the concrete mast, because in this case that would have to be Swiveling the trusses still done in height, in which the end is separated or the subsequent installation of the new tip is done. This work can only be done with one Tree can be executed. The so far known stick trees are too short for this. The rope anchors to which these cane trees are connected also hinder the Rehabilitation work. On the other hand, only stick trees are suitable for this work, because only those can be transported to the masts, which did not hit with a crane can be. The same applies to the assembly of the new top, at which the Steel trusses are already attached.

Dann wird, wie Fig. 2 zeigt, eine Steckleiter 8 lösbar an dem Betonmast 30 aufgebaut, so dass dieser bestiegen werden kann. In einem vorher bestimmten Abstand von der Unterseite der Traversen 31 nach unten werden zunächst zwei Schellen 6 und 7, die eine Doppelschelle gemäß Fig. 3 bilden, an dem Betonmast 30 befestigt. Dafür wird die Schelle 6 an dem Betonmast 30 lösbar montiert, derart, daß sie diesen umgreift, während die Schelle 7 horizontal nach außen weisend an der Schelle 6 befestigt ist. Das zweite Ende 2B des Stahlrohrs 2 ist mit einem abgeflachten Anschlußstück 2F versehen. Dieses wird bei der Montage des Stockbaums 1 zwischen der Schelle 7 drehbar eingehängt. Im Anstand von 1,0m über der Schelle 6 werden dann zwei weitere Schellen 9 und 10 ebenfalls lösbar montiert. Die Schelle 9 wird so befestigt, daß sie den Betonmast 30 umgreift. Die Schelle 10 wird an der Schelle 9 so gehaltert, daß sie horizontal nach außen weist, und zwar so, daß sie sich in einem Bereiche zwischen den Leiterseilen 33 der beiden Traversen 31 befindet. Das Gleiche gilt auch für die oben beschriebene Schelle 7. Damit kann der Stockbaum 1 ebenfalls in einem Bereich zwischen den Leiterseilen 33 der beiden Traversen aufgestelti werden. In Fig. 3 sind die beiden miteinander verbundenen Schellen 9 und 10 in einer Draufsicht zu sehen. Die Schelle 9 besteht aus zwei Bauelementen 9X, die jeweils fünf Kanten 9K und 9L aufweisen. Diese sind im Halbkreis angeordnet. Dabei sind die zweiten Hälften der beiden einander gegenüberliegenden Kanten 9K im rechten Winkel nach außen gebogen, so daß sie flächige Verlängerungen 9V. Jeweils zwei Verlängerungen 9V sind zusammengefügt und über eine Schraube 9S miteinander verbunden sind. Der Innendurchmesser der Schelle 9 ist einige Zentimeter größer als der Außendurchmesser des Betonmasts 30. Der zwischen der Schelle 9 und dem Betonmast 30 verbleibende Raum ist bereichsweise mit Bauelementen 9Z aus Hartholz ausgefüllt. Damit wird der Betonmast 30 vor Beschädigungen geschützt. Die Bereiche der Bauelemente 9Z, die dem Betonmast 30 zugewandt sind, sind konkav geformt, so daß sie sehr gut an dem Betonmast 30 anliegen. Um die Montage der Schelle 9 zu vereinfachen sind die Bauelemente 9Z lösbar an der Innenseite der Schelle 9 befestigt. Bei Bedarf können sie gegen breitere oder schmalere Bauelemente 9Z ausgetauscht werden, je nach dem wie groß der Außendurchmesser des jeweiligen Betonmasts 30 ist. An den beiden Kanten 9L, die parallel zu den Leiterseilen 33 ausgerichtet sind, sind außen jeweils drei Ösen 9H für die Halterung der Leiterseile 33 befestigt. Die Schelle 10 ist aus zwei halbkreisförmigen Bauelementen 10X zusammengesetzt. Der Innendurchmesser der Schelle 10 ist an den Außendurchmesser des Stockbaums 1 angepaßt. Jedes Bauelement 10X weist an seinen beiden Enden jeweils eine flächige Verlängerung 10V auf. Jeweils zwei aneinander gefügte Verlängerungen 10V sind über wenigstens eine Schraube 10S lösbar verbunden. Zwei zusammengefügte Verlängerungen 10V sind zur Befestigung der Schelle 10 an der Schelle 9 zwischen zwei Verlängerungen 9V angeordnet. Sie werden zusammen mit diesen von einer Schraube 9S zusammengehalten. Die Installation der Schellen 9 und 10 geschieht erst dann, wenn der Stockbaum 1 so positioniert ist, daß seine Längsachse senkrecht ausgerichtet ist und das Endstück 3 nach oben weist, so daß das Stahlrohr 2 durch die Schelle 10 hindurchgeführt werden kann.In order to climb the cane tree 1, a ladder 1S is releasably attached thereto. The mounting of the ladder 1S already takes place during the assembly of the cane tree 1 at the bottom 100. Before the cane tree 1 is attached to the concrete mast 30, are suspended from the insulator chains 32 of the concrete mast 30 lines 33rd Grounded at the neighboring pylons. Then, as shown in FIG. 2, a plug-in conductor 8 solvable built on the concrete pole 30 so that it can be climbed. In a before certain distance from the bottom of the trusses 31 are down first two clamps 6 and 7, which form a double clamp according to FIG. 3, on which Concrete mast 30 attached. For the clamp 6 is detachably mounted on the concrete pole 30, such that it engages around it, while the clamp 7 pointing horizontally outwards is attached to the clamp 6. The second end 2B of the steel pipe 2 is flattened Connector 2F provided. This is during the assembly of the tree trunk 1 suspended between the clamp 7 rotatable. In the decency of 1.0m above the clamp 6 Then two more clamps 9 and 10 are also detachably mounted. The clamp 9 is attached so that it encompasses the concrete pole 30. The clamp 10 is at the Clamp 9 held so that it points horizontally outward, in such a way that they themselves is located in a region between the conductor cables 33 of the two trusses 31. The The same applies to the above-described clamp 7. Thus, the cane tree 1 also aufgestelti in an area between the conductors 33 of the two trusses become. In Fig. 3, the two interconnected clamps 9 and 10 in to see a plan view. The clamp 9 consists of two components 9X, each have five edges 9K and 9L. These are arranged in a semicircle. there are the second halves of the two opposite edges 9K in the right Angle bent outward, so that she flat extensions 9V. Two each Extensions 9V are assembled and connected by a screw 9S are connected. The inner diameter of the clamp 9 is a few inches larger than the outer diameter of the concrete mast 30. The between the clamp 9 and the concrete mast 30 remaining space is in areas with elements 9Z hardwood filled. Thus, the concrete pole 30 is protected from damage. The areas the components 9Z facing the concrete mast 30 are concave-shaped, so that they rest very well on the concrete pole 30. To the assembly of the clamp 9 too simplify the components 9Z are releasably attached to the inside of the clamp 9. If necessary, they can be exchanged for wider or narrower components 9Z Depending on how large the outer diameter of the respective concrete mast 30th is. At the two edges 9L, which are aligned parallel to the conductor cables 33, are each outside three eyelets 9H attached to the holder of the conductor cables 33. The clamp 10 is composed of two semicircular components 10X. The inner diameter the clamp 10 is adapted to the outer diameter of the tree trunk 1. Each component 10X has at its two ends in each case a planar extension 10V on. Two mutually joined extensions 10V are over at least one screw 10S releasably connected. Two joined extensions 10V are for attaching the clamp 10 to the clamp 9 between two extensions 9V arranged. You will get along with these from a 9S screw held together. The installation of the clamps 9 and 10 happens only then the cane tree 1 is positioned so that its longitudinal axis is oriented vertically and the end piece 3 facing upward, so that the steel pipe 2 passed through the clamp 10 can be.

    Wie Fig. 2 zeigt ist auf einer der beiden Traversen 31 eine große Rolle 11 montiert. Eine weitere Rolle 12 wird, wie in Fig. 4 dargestellt, am Fuß des Betonmasts 30 installiert. Der zusammengebaute Stockbaum 1 wird dann mit seinem abgeflachten Anschlußstück 2F an der Schelle 7 drehbar befestigt. Hierfür wird ein Seil 13 einer Doppelstockwinde 14 gemäß Fig. 4 über die beiden Rollen 12 und 11 geführt und mit dem Anschlußstück 2F des noch am Boden 100 liegenden Stockbaums 1 verbunden. Der Stockbaum 1 wird mit dem Seil 13 soweit nach oben gezogen, bis sich das flache Abschlußstück 2F zwischen der Schelle 7 befindet und mit der Schraube 7S so montiert werden kann, daß der Stockbaum 1 zum Betonmast 30 hin und von diesem weg geschwenkt werden kann. Anschließend wird das Seil 13 mit dem freien Ende des Auslegers 4 verbunden. Dann wird der Stockbaum 1 nach oben gekippt, so daß das Endstück 3 nach oben weist. Am freien Ende des Auslegers 4 ist, wie Fig. 1 zeigt, hierfür eine Lasche 4L mit einer Öse 4H vorgesehen. Mit einem zweiten Seil 15 der Doppelstockwinde 14, das mit dem freien Ende des Endstücks 3 verbunden ist, wird der Stockbaum 1 während des Aufrichtens so weit vom Betonmast 30 abgehalten, bis für das Seil 13 ein ausreichender Winkel für das direkte Kippen bis in die endgültige Stellung des Stockbaums 1 erreicht ist.As shown in FIG. 2, a large roller 11 is mounted on one of the two traverses 31. A another roller 12 is, as shown in Fig. 4, installed at the foot of the concrete mast 30. The assembled tree 1 is then with its flattened fitting 2F rotatably attached to the clamp 7. For this purpose, a rope 13 a double-deck winch 14 as shown in FIG. 4 over the two rollers 12 and 11 out and with the Connecting piece 2F of still lying on the ground floor 100 tree 1 connected. Of the Tree 1 is pulled with the rope 13 so far up to the flat end piece 2F is located between the clamp 7 and with the screw 7S so mounted can be that the cane tree 1 pivoted to the concrete mast 30 and away from it can be. Subsequently, the rope 13 with the free end of the boom 4 connected. Then the cane tree 1 is tilted up so that the tail 3 points upwards. At the free end of the boom 4, as shown in FIG. 1, for this purpose a tab 4L provided with an eyelet 4H. With a second rope 15 of the double-deck winch 14, which is connected to the free end of the end piece 3, the Tree 1 during the erection so far from the concrete mast 30 barred until for the rope 13 a sufficient angle for direct tilting to the final position of the tree 1 tree is reached.

    Wie Fig.1 zeigt, wird an einer Schelle 18 beidseitig jeweils eine zugfeste Leine 17 (hier nur eine dargestellt) für das Aufrichten des Stockbaumes 1 befestigt. Die Schelle 18 ist in einem Abstand von 0,30m oberhalb der Schelle 9 montiert ist. Die Leinen 17 werden über die Leiterseile 33 bis zum Boden 100 geleitet. Sie werden zunächst beim Aufrichten zum seitlichen stabilisieren des Stockbaums 1 benutzt. Dabei werden sie vom Boden 100 aus von Monteuren per Hand geführt. Wenn die Längsachse des Stockbaum 1 senkrecht ausgerichtet ist, werden die beiden Schellen 9 und 10 so installiert, wie oben beschrieben. Anschließend wird der Stockbaum 1 in der Schelle 10 statisch belastbar fixiert. Dann werden die zweiten Enden der Leinen 17 im Boden 100 verankert. Um die Arbeiten nicht zu behindern, wird eine der Leinen 17 zuvor auf eine Schelle 19 umgehängt, die unmittelbar über der Schelle 18 installiert ist. Durch die beiden Leinen 17 wird eine größere Sicherheit und ein geringeres Eigengewicht des Stockbaums 1 erreicht. Nach dem der Stockbaum installiert ist, werden die Leiterseile 33 ausgeklemmt und auf der Schelle 9 abgehängt. Diese ist auf den Seiten, die parallel zu den Leiterseilen 33 verlaufen hierfür mit jeweils drei Ösen 9H versehen, wie sie in den Figuren 1, 3 und 5 dargestellt sind. Die Leiterseile 33 werden dabei nur um etwa 1,0m tiefer gehängt. Damit sind die senkrechten Abstände zu unterkreuzenden Objekten (hier nicht dargestellt) weiterhin ausreichend. Kosten für Gerüstbauten und/oder sonstige Maßnahmen werden somit vermieden.As shown in FIG. 1, a tension-resistant line 17 (here only one shown) for the erection of the tree trunk 1 attached. The clamp 18 is at a distance of 0.30 m above the clamp 9 is mounted. The lines will be 17 passed over the conductor cables 33 to the bottom 100. You will first sit up used to stabilize the tree 1 sideways. They will be off the ground 100 out of technicians by hand. When the longitudinal axis of the tree 1 vertically aligned, the two clamps 9 and 10 are installed as above described. Subsequently, the tree trunk 1 in the clamp 10 is static loadable fixed. Then the second ends of the lines 17 are anchored in the floor 100. To the Work is not hindered, one of the lines 17 is previously transferred to a clamp 19, which is installed immediately above the bracket 18. Through the two lines 17 a greater safety and a lower dead weight of the tree trunk 1 is achieved. After the cane tree is installed, the conductors 33 are disconnected and hung on the clamp 9. This is on the sides, which are parallel to the conductors 33 run for this purpose each with three eyelets 9H, as shown in Figures 1, 3 and 5 are shown. The conductors 33 are hung only about 1.0m deeper. Thus, the vertical distances to unterkreuzenden objects (not here shown) still sufficient. Costs for scaffolding and / or other measures are thus avoided.

    Die Traversen 31 aus Beton, die auszuwechseln sind, werden wie in Fig. 5 dargestellt, mit je einem Schlupf 20, der jede Traverse 31 umgreift, an einem Gabelanker 21 aufgehängt. Wie Fig.6 zeigt wird der Gabelanker 21 an dem über die Rollen 22 und 23 laufendem Seil 28 eingehängt. Die Rollen 22 und 23 sind an einer Lasche 3L des Endstücks bzw. einer Lasche 4L des Auslegers 4 angeordnet. Das abzuschneidende, obere Ende des Betonmasts 30A wird mit einem Zughub (hier nicht dargestellt) horizontal abgefangen. Wie in Fig. 5 dargestellt werden an den Enden der Traversen 31 die Leinen 25 und 26 befestigt und der Betonmast 30 gemäß der Schnittlinie A-A' horizontal abgeschnitten. Das abgeschnittene Ende 30A des Betonmasts 30 mit den beiden Traversen 31 wird mit dem Zughub in die Lotrechte nachgelassen. Der Ausleger 4 wird nun mit Hilfe der Leinen 25 und 26 um 90° so geschwenkt, daß die Längsachsen der beiden Traversen 31 parallel zu den Leiterseilen 33 verlaufen. Da der Ausleger 4 eine Länge von 0,80 m aufweist, hängt das abgeschnittene Ende 30A des Betonmasts 30 mit den Traversen 31 vor den Leiterseilen 33, die an den Ösen 9H der Schelle 9 abgehängt sind. Damit kann das Ende 30A des Betonmasts 30 ohne Schwierigkeiten auf den Boden 100 abgelassen werden.Concrete trusses 31 to be replaced are as shown in Fig. 5, each with a slip 20, which embraces each traverse 31, suspended from a fork armature 21. As shown in Fig.6 shows the fork armature 21 at the on the rollers 22 and 23rd hanging rope 28 is suspended. The rollers 22 and 23 are on a tab 3L of the tail or a tab 4 L of the boom 4 is arranged. The top to be cut off End of the concrete mast 30A becomes horizontal with a pulling stroke (not shown) intercepted. As shown in Fig. 5 at the ends of the trusses 31, the lines 25 and 26 attached and the concrete pole 30 according to the section line A-A 'horizontal cut off. The cut end 30A of the concrete mast 30 with the two trusses 31 is lowered with the Zughub in the vertical. The boom 4 is now with the help of the lines 25 and 26 pivoted by 90 ° so that the longitudinal axes of two trusses 31 parallel to the conductors 33 run. Since the boom 4 a Length of 0.80 m, depends the cut end 30 A of the concrete mast 30th with the trusses 31 in front of the conductor cables 33, which are suspended on the eyelets 9H of the clamp 9 are. Thus, the end 30A of the concrete mast 30 without difficulty the bottom 100 are drained.

    Fig. 7 zeigt eine Spitze 35 mit welcher der Betonmast 30 gemäß Fig. 8 jetzt an seinem oberen Ende 30A versehen wird. Diese ist aus einem handelsüblichen, verzinkten Stahlblech gefertigt. Sie hat einen Querschnitt, der von acht gleich langen Kanten (hier nicht dargestellt) begrenzt wird. Die Spitze 35 ist so ausgebildet, daß sie den Betonmast 30 über eine definierte Länge hüllenartig umschließt. Da Betonmaste generell nicht absolut rund und gerade sind und ihr Durchmesser nicht Millimeter genau gemessen werden kann, wird die Spitze 35 mit einem Durchmesser versehen, der fünf mm größer ist als der des Betonmastes 30. Die Länge des Abschnitts 36, mit dem die Spitze 35 das obere Ende 36A überlappt, wird vom Durchmesser des Betonmastes 30 mitbestimmt. Sie muß mindestens das 1,5-fache des Durchmessers betragen, den der Betonmast 30 an der Oberkante der Schelle 9 aufweist. Hat der Betonmast 30 dort beispielsweise einen Durchmesser von 0,38m, muß die Länge des Abschnitts 36 mindestens 0,57 m betragen. Die Länge der Spitze 35 ergibt sich somit aus der Länge des Bereiches, der am Betonmast 30 beschädigt und somit zu ersetzen ist, zuzüglich der Länge der erforderlichen Überlappung 36. Bei dem hier dargestellten Ausführungsbeispiel wird der Betonmast 30 instandgesetzt. Eine zusätzliche Erhöhung des Betonmastes 30 ist nicht vorgesehen. Da der Betonmast 30 auf eine Länge von 1,0m beschädigt ist (hier nicht dargestellt), ergibt sich bei dem hier dargestellten Ausführungsbeispiel somit eine Mindestlänge der Spitze 35 von 1,00+0,57 = 1,57 m. Wird die Länge des Abschnitts 36 aus Gründen der Sicherheit auf das dreifache des Durchmessers vorzugsweise auf 1,14 m erhöht, so ist eine Spitze 35 mit einer Länge von 2,14 m zu verwenden. Die Spitze 35 ist an ihrem zweiten, nach oben weisenden Ende mit zwei nach außen weisenden Flanschen 37 und 38 versehen. Die Höhe der Flansche 37 und 38 beträgt etwa 0,30m. Diese ist zu der Länge von 2,14 m hinzuzurechnen, so daß sich eine Gesamtlänge der Spitze 35 von etwa 2,44 m ergibt. Die Flansche 37 und 38 sind in einer gemeinsamen Ebene senkrecht zur Längsachse der Traverse 31 angeordnet. An jedem Flansch 37, 38 ist eine Traverse 31 aus feuerverzinktem, beschichtetem Stahlblech angeschraubt. Die Spitze 35 ist zudem so ausgebildet, daß die neuen Traversen 31 nach der Installation der Spitze 35 auf dem Betonmast 30 in der gleichen Höhe wie die ursprünglichen Traversen 31 angeordnet sind.Fig. 7 shows a tip 35 with which the concrete pole 30 shown in FIG. 8 now at his upper end 30A is provided. This is made of a commercial, galvanized Made of sheet steel. It has a cross-section of eight edges of equal length (here not shown) is limited. The tip 35 is designed to be the concrete pole 30 envelops over a defined length envelope. As concrete poles in general not absolutely round and straight and their diameter is not measured to the nearest millimeter can be made, the tip 35 is provided with a diameter of five mm greater than that of the concrete mast 30. The length of section 36 with which the top 35 overlaps the upper end 36A is determined by the diameter of the concrete mast 30. It must be at least 1.5 times the diameter that the Concrete mast 30 at the upper edge of the clamp 9 has. Does the concrete mast 30 there, for example a diameter of 0.38m, the length of section 36 must be at least 0.57 m. The length of the tip 35 thus results from the length of Area which is damaged on the concrete pole 30 and thus must be replaced, plus the Length of the required overlap 36. In the embodiment shown here the concrete mast 30 is repaired. An additional increase in the concrete mast 30 is not provided. As the concrete pole 30 is damaged to a length of 1.0m is (not shown here), results in the embodiment shown here thus a minimum length of the tip 35 of 1.00 + 0.57 = 1.57 m. Will the length of section 36 for reasons of safety to three times the diameter preferably increased to 1.14 m, so a peak 35 with a length of 2.14 m to use. The tip 35 is at its second, upwardly facing end with two outwardly facing flanges 37 and 38 provided. The height of the flanges 37 and 38 is about 0.30m. This is to be added to the length of 2.14 m, so that gives a total length of the tip 35 of about 2.44 m. The flanges 37 and 38 are arranged in a common plane perpendicular to the longitudinal axis of the traverse 31. At each flange 37, 38 is a traverse 31 of galvanized, coated Screwed steel sheet. The tip 35 is also designed so that the new traverses 31 after installing the top 35 on the concrete pole 30 in the same Height as the original trusses 31 are arranged.

    Die Spitze 35 wird mit den montierten Traversen 31 und den Isolatorenketten 32 mit Hilfe des Stockbaums 1 in der gleichen Weise angehoben, wie das abgetrennte Ende 30A des Betonmasts 30 zuvor abgelassen wurde, und zwar so hoch, daß sie über dem Betonmast 30 hängt. Mit Hilfe der Leinen 25 und 26 wird der Ausleger 4 wieder in seine ursprüngliche Position zurückgeschwenkt. Die Spitze 35 wird mit dem in Fig. 6 dargestellten Seil 27 über die Rolle 23 zur Mitte des Betonmasts 30 gezogen und dann mit den beiden über die Rollen 12 und 12A am Fuß des Betonmasts 30 laufenden Seilen 27 und 28 der Doppel-Stockwinde 14 abgesenkt, bis die Spitze 35 auf der Schelle 9 aufsitzt. Die Traversen 31 werden ausgerichtet, die Spitze 35 wird geerdet und mit schwundfreien Schnellzement (hier nicht dargestellt) ausgegossen. Um das Ausfließen des Schnellzements zu verhindern, wird auf die Schelle 9 ein weiches Material gelegt. Nachdem der Schnellzement ausgehärtet ist, werden die Leiterseile 33 wieder an die Isolatorenketten 32 angehängt. Anschließend werden der Stockbaum 1, die Schellen 6, 9, 18 und 19, die große Rolle 11 und die Steckleiter 8 abgebaut, die Erdungen an den Nachbarmasten ausgebaut und die Leitung wird wieder in Betrieb genommen.The tip 35 is with the assembled trusses 31 and the insulator chains 32 with Help the cane tree 1 raised in the same way as the severed end 30A of the concrete mast 30 was previously drained, and so high that they are above the Concrete mast 30 hangs. With the help of the lines 25 and 26 of the boom 4 is back in his swung back original position. The tip 35 is shown with the in Fig. 6 Rope 27 pulled over the roller 23 to the center of the concrete mast 30 and then with the two on the rollers 12 and 12A at the foot of the concrete mast 30 current ropes 27 and 28 of the double-deck winch 14 lowered until the top 35 on the clamp. 9 seated. The trusses 31 are aligned, the tip 35 is grounded and with shrinkage-free rapid cement (not shown here) poured out. To the outflow To prevent the quick cement, a soft material is placed on the clamp 9. After the rapid cement has cured, the conductor cables 33 are returned to the Insulator chains 32 attached. Then the cane tree 1, the bells 6, 9, 18 and 19, the large roller 11 and the plug conductor 8 degraded, the groundings to the Neighboring masts expanded and the line is put back into operation.
