    Method of placing a railway portal foundation block.
    This invention relates to placing a prefabricated element next to a railroad formed from two parallel rails for transporting people and goods by a train. In particular, the prefab element to be placed is made of concrete and belongs to the overhead line for the electrical supply of the train, for example a foundation element for the gantry that carries the overhead line, or an anchor block to which the pull braces of the overhead line are attached. The overhead contact line includes the so-called contact wires along which the pantograph is sliding off the train.
    Technical background provides eg NL1016588C1 (Gebr. Van Leeuwen Harmelen bv / Van der Worp bv). That document discusses the use of a tension anchor for improving the portal foundation.
    Up to now, the placement of such a prefab element has been carried out as follows: On the rail of the track that has already been installed, a marking has been applied which forms a reference point for the position of the prefab element in the longitudinal direction of the track. With a rail crane running over the railroad in question, a prefabricated element is lifted and brought freely suspended from the crane boom to just above its final installation location and thus freely suspended (on a hoisting chain) aligned with the marking on the rail at the correct distance from the railroad. Because the prefab element is freely attached to the crane boom, this alignment is a time-consuming operation with the risk of an accident. It often happens that after the prefab element has been set down, this has to be lifted a little further from the ground if it appears that the desired accuracy has not yet been achieved.
    The invention aims to work faster, safer and more accurately. To this end, it is proposed to use one or more stop elements which assume a fixed spatial position during placement of the prefab element, preferably by fixing means, and against which the raised prefab element is supported so that the relevant stop element moves a further and / or rotation of the prefab element in a certain direction, preferably in two mutually perpendicular directions, impedes or makes it impossible and preferably support is maintained while the prefab element is lowered onto the substrate, in which case the stop element also functions as a guide element. Before the prefab element is placed, the location and position of the stop elements are adjusted, preferably by adjusting means, in accordance with the desired location of the prefab element along the railroad track. Adjusting the stop elements can be done quickly, accurately and safely and does not require the presence of the prefab element.
    The direction or directions are preferably horizontal directions. Preferably, the prefab element, suspended from the hoisting device, is moved with a horizontal component towards the one or more stop elements to come into contact with it and / or be prevented or stopped by these stop elements from moving further in this direction.
    The stop elements are preferably fixed to the rail track by fixing means, preferably temporarily, for example a rail or cross-member or other component thereof which is sufficiently stationary to guarantee the required fixed spatial position of the stop element in the light of the mechanical load caused by the stop element. freely hanging prefab element of possibly 12 thousand kg. or more.
    The stop elements are preferably part of a frame, preferably spatial frame, preferably equipped with fixing means and / or adjusting means.
    The fixing means are preferably adapted for temporary fixing so that the stop elements can easily be reused. For example, the fixing means comprise gripping or hooking members for gripping or hooking fixing with, for example, a rail or crossbar.
    Preferably one or more of the following applies: prefabricated element hangs on a flexible tension member (e.g. hoisting chain) while it is supported against the stop elements and / or is engaged at its top, for example at its upwardly projecting mechanical fastening means, such as threaded ends the crane; the stop elements only have a restraining action against movement in the horizontal plane by the prefabricated element supporting it; the stop elements permit vertical up and / or down movement of the prefab element supported against it; one or more stop elements provide a physical obstacle to the prefabricated element against movement in one direction, preferably so that, viewed in horizontal direction, the prefabricated element is at two separate locations (preferably at least 50 centimeters or 1 meter apart) stopped in that one direction, for example, so that a tendency to turn is prevented; one or more stop elements provide a physical obstacle to the prefab element against movement in the other direction; one direction and the other are perpendicular to each other; the stop elements which provide a physical obstacle to movement in one direction provide mechanical resistance to movement in the other direction by the prefabricated element supporting it, for example in that friction means such as a rubber liner are used; two stop elements are perpendicular to each other; two stop elements are integrated, for example a corner profile, preferably oriented vertically; the stop elements are adapted to prevent or prevent movement towards the rail track and / or parallel thereto by the prefab element; the railroad is for public civil purposes, for example constructed as a railroad to travel by train from one city to another in a country such as the Netherlands, for example from Haarlem to Leiden or from The Hague to Utrecht or from Zwolle to Assen ; a foundation bed or excavation is made next to the rails, on the bottom of which the prefab element is placed; the prefab element is a portal foundation, such as type V2b (butterfly block) or an anchor block, such as type AN4 (wing block); the prefab element weighs at least 2 or 3 thousand kilos; the prefab element measures one or more of at least 1 meter long, wide, high and / or is made of reinforced concrete; the prefab element is founded on steel, such as sand or other soil substrate.
    For the frame, preferably one or more of the following applies: the frame contains at least one frame part, such as arm or girder, to extend between the track and one or more stop elements; the frame contains collapsible parts, such as telescoping parts, for adjusting the stop elements or for trasport or storage; the frame part comprises a substantially horizontal and / or substantially vertical, preferably downward, extending part, for example for maintaining a stop element at a level below the track or sleepers thereof; the frame, such as the frame part, comprises means for adjusting the length and / or height; the frame is adapted to engage both rails simultaneously with fixing means; the fixing means are adapted for fixing in one or more of the longitudinal direction, transverse direction, upward, downward direction of the track; two frame parts maintain a mutual gap in the longitudinal direction of the track; two frame parts are mutually fixed by fixing means; a frame part carries a stop element at one end.
    The invention is further elucidated on the basis of an example of protection which is not limiting, with reference to the accompanying drawing. This shows in:
    FIG. 1 a double railway or railroad track in perspective;
    FIG. 2 is a cross-sectional view of a part of the track of FIG. 1;
    FIG. 3a-d show various views of the frame of the invention when placing a wing anchor block AN4.
    FIG. 4a-c show various views of the frame of the invention when placing a V2b butterfly foundation block.
    FIG. 5a-c show various views of the frame of the invention when placing an F8 foundation block;
    FIG. 6 shows a detail of FIGS. 3a, 3b, 4a and 5a; and
    FIG. 7 a simplification of the representation of FIG. 4c.
    The railway of fig. 1 is electrified, so there are portals (one of which is visible) along it, which carry the contact wire. FIG. 2 shows how the gantry leg 6 is founded by a prefab element 5 based on steel next to or in the edge area of the ballast bed 2 which carries the sleepers 3 with the rails 4 thereon.
    After the rails 4 have been definitively placed, the prefab elements 5 are placed, the crane vehicle running on the rails.
    FIG. 3 to 7 show the frame used to facilitate the placement of the prefab element.
    The frame comprises two frame parts, in this case box profiles, which have claws on their underside for engaging with the rail heads and on which stop elements are located. The box sections have a horizontal part above the rails 4 and a vertical downward section next to the rails with a stop element at the lower end. By immovably coupling the frame to the rails 4, the stop elements are immovably held at a place to the side of and below the level of the sleepers, a short distance above the substrate on which the prefab element is placed.
    FIG. 3a and 3b show the left and right hand side of FIG. right frame part. The right-hand frame part further brings the associated stop element further to the side of the rails 4, this is necessary because of the shape of the prefab element. The right-hand frame part has a greater length for this purpose.
    FIG. 4a and 5a are a representation of the left-hand frame part in Fig. 4b and Fig. 5b, respectively. The associated right-hand frame part is identical in shape and length, and the right-hand frame part lacks the corner profile.
    FIG. 6 shows the fixation in detail. The fixation on the rail 4 on the left in the drawing (the distal rail) is such that the frame is retained in upward and downward direction and is also retained in the longitudinal direction of the rail. On the rail 4 on the right in the drawing (the proximal rail) the fixation is such that free upward movement is allowed, only downward movement is blocked. The fixation on both rails is such that movement in both horizontal directions perpendicular to the rail 4 is blocked. Additional fixation is conceivable, for example on the proximal rail upwards, which, however, is unnecessary because the stop element is placed at a level below the level of the rails 4.
    The heavy angular profile on the left in the drawing of Fig. 7 provides a stop element for the two mutually perpendicular directions (indicated by the two arrows), the frame part on the right in the drawing of Fig. 7 only provides for stopping movement towards the rails 4 a stop element (indicated by the single arrow). The prefab element 5 is imaginary.
    The stop elements are positioned low to engage on the base of the prefab element. Placement at a higher level is an alternative conceivable.
    Alternatively, it is conceivable to fix the stop elements to the hoisting device which, for example, rides on the rails 4. Other forms of the components are conceivable.
    The frame shown can easily be picked up by the rail crane and taken to the next location for placement of a prefab element or loaded onto a truck.
    Dimensions in the drawing are in millimeters.
