BACKGROUND OF THE INVENTION

The invention relates to a method of reinforcing a embankment, wherein the embankment is reinforced by installing a pen-5 gerlate on the embankment.

The invention further relates to an arrangement for reinforcing the embankment.

Benches, such as rail embankments or road embankments, need to be reinforced if the embankments are poorly formed and sunk. For example, the Edel-10 may have reinforcement of track bumps if the berths cannot withstand the axle loads of newer, heavier trains or new high-speed trains. In practice, the only viable solution is to reinforce the embankments with embankment slabs. The reinforcement is done by dismantling the embankment and the orbit above it and installing the embankment slab. Thereafter, the embankment and 15 orbit are rebuilt on the embankment slab. Such a solution is very laborious and difficult to implement and requires very long traffic disruptions.

BRIEF DESCRIPTION OF THE INVENTION The object of the present invention is to provide a novel method and arrangement for reinforcing the embankment.

. The method according to the invention is characterized by installing support piles on each side of the embankment, installing '···' primary beams parallel to the embankment on either side of the embankment; fasten the mounting sleeve from the primary beam to the other through the embankment, install: the slab element inside the mounting sleeve and remove the mounting sleeve from the top of the slab element.

· / ": The arrangement according to the invention is further characterized in that the arrangement comprises support piles arranged on each side of the embankment,: on top of the support piles parallel to the embankment on each side of the embankment, ··. Fitted primary beams, mounting sleeve which can be mounted to be installed inside the mounting sleeve.:: slab elements.

The essential idea of the invention is to first install the support piles. * · *. on each side of the embankment. Primary beams are installed on top of the support piles parallel to the embankment on each side of the embankment. Thereafter, the mounting sleeve 35 is mounted from one primary beam to another through the embankment. After installing the mounting sleeve 2 116152, install the slab element inside the mounting sleeve and then remove the mounting sleeve over the slab element; s. When done in this way, the reinforcement of the embankment can be accomplished relatively quickly and with relatively little effort. The mounting sleeve can be quite 5 thin-walled and it is quite easy to push or pull it through the embankment in the right direction, for example compared to a solid concrete slab. In addition, the mounting sleeve does not cause significant deformation of the bench and thus does not increase the need for maintenance of the track on the bench, for example. Further, the road or track above the embankment may be at least substantially during normal operation during operation and long traffic breaks are not substantially required.

The idea of one embodiment is that, at the same time as the installation sleeve is removed, a lip plate is installed on the gap between the two slab elements to prevent the earth from falling between the elements. Furthermore, the lip plate allows the elements to be displaced in the side-15 direction, i.e., to minimize the gap between the elements. Another idea is that a support beam is provided inside the mounting sleeve to support the mounting sleeve when installed through the embankment and which support beam is removed when installing the slab tile element inside the mounting sleeve. In this case, in the mounting step of the mounting sleeve, the mounting sleeve is very well supported by the support beam and in the final stage of the installation of the slab element, the slab element ....: supports the mounting sleeve.

Detailed Description of the Invention

Fig. 1a shows the embankment 1. Above the embankment 1 is a train track 2.

Initially, the support piles 3 will be piled on each side of the embankment 1 as shown in Figure 1a. When the support piles 3 are installed, primary beams 4 parallel to the embankment are installed on each side of the embankment as shown in Figure 1b. Before installing the primary beams 4, it is of course possible to cut the top of the piles 3 to a suitable height if, after they have been installed, the height of the support piles 3 is not exactly correct.

According to Fig. 1c, the mounting sleeve 5 is inserted by means of a push-on jack 6. The mounting sleeve 5 is, for example, a C profile made of steel. The mounting sleeve 5 may have longitudinal stiffeners.

Next, as shown in Fig. 1d, a pusher jack 6 is inserted into the mounting sleeve 5 by means of a pusher jack 6. The slab element 7 is, for example, a reinforced concrete element with a sufficient load-bearing capacity.

After installation of the slab element 7, the mounting sleeve 5 is pulled off the slab element 7 by a pulling pin 8 as shown in Figure 1e.

Before pulling the mounting sleeve 5, it can be attached to its end by, for example, welding a lip plate 9, and when pulling the mounting sleeve 5, it pulls the lip plate 9. Naturally, the lip plate 9 does not fit until the other lath plate 7 is mounted beside the mounting sleeve. over the gap between the slab element 7.

Push-in jacks 6 and / or pull jacks 8 may be supported during installation ·:> ·, for example in primary beams 4 and / or in support piles and / or pre-installed pen. * ·. for the glazing elements 7. When installing the first terrain tile elements 7. ""; additional supports and / or additional anchors may be used if necessary.

; Figure 2a shows a situation in which three terracotta slab elements 7 have already been installed and then · ;;; mounting sleeve 5. Inside the mounting sleeve 5 is a support beam 10 which supports the '* ·' mounting sleeve 5 during installation and before the floor slab element 7 is fitted inside the mounting sleeve 5. The support beam 10 may be substantially equal to the mounting sleeve 5.

The situation of Fig. 2b shows a case where the slab element 7. [*. has already been inserted into the mounting sleeve 5.

In Fig. 2c, the lip plate 9 is pulled over by two adjacent pen-; on the seam between the glaze element 7. The lip plate 9 prevents the ground from falling between the elements. Thus, at this stage, it is possible to move the installed slab element 7 sideways. For this directional displacement of the primary beams 2, a pushing jack 6 similar to the longitudinal pushing of the mounting sleeve 5 and the slab elements 7 may be used. Fig. 2d shows a situation in which the recently installed terracotta element 7 is displaced to the adjacent terracotta element 7, i.e. the gap 5 between them is arranged small. Further, in the case of Figure 2d, the lip plate 9 is removed from the slot.

Fig. 3 shows a mounting sleeve 5 with a support beam 10 fitted inside. The mounting sleeve 5 comprises a solid top surface 11 and side walls 12, whereby the mounting sleeve 5 is in the form of a C-beam. Preferably, the sleeve 5 of the mounting 10 is open at the bottom, whereby during its installation and after its installation prior to the installation of the slab element 7, the ground in the embankment also acts as a support for the mounting sleeve 5. The mounting sleeve 5 is also supported by a support beam 10. If desired, the mounting sleeve 5 can also be closed at the bottom and the sides, so that only its ends are open.

15 Lower flanges 13 are formed at the lower ends of the side walls 12, on which the support beam 10 or the slab element 7 rest. The mounting sleeve 5 is further formed with upper flanges 14 which extend beyond the side walls 12. The upper flanges 14, in turn, prevent the ground from entering the gap between the embankment slab elements 7 to be installed. Further, the upper flanges 14 guide the passage of the mounting sleeve 5 when mounted through the embankment 1. For example, the mounting sleeve 5 is supported by the top panel 14 on the upper surface of the previous terracotta slab element 7.

·: ··: The support beam 10 shown in Figure 3 comprises three support beams 15.

. ** ·. The support beams 15 are connected at their lower part by a transverse bracket 16, which may be formed of separate pieces or formed integral. Transverse bracket; Thus, 16 rests on the lower flanges 13 of the mounting sleeve 5.

The upper ends of the support beams 15 and the lower edges 13 of the transverse brackets 13; Sliding surfaces 17 are formed in the insertion portions which facilitate removal of the support beam 10 from inside the mounting sleeve 5.

The support beam 10 and the mounting sleeve 5 are formed in such a way that they i.i · 30 displace the ground as little as possible during installation, thus making it as easy to install them as possible. In the direction of movement of the support beam 10, in the direction of movement, an end plate can be fitted, which can be fixed to the floor slab element 7, for example by bolts. In this case, this end plate still pushes the ground inside the mounting sleeve 5 as efficiently as possible., 35 when installing the slab element 7. Thus, when a support beam 10 is used on the inside of the mounting sleeve 5, the support beam 10 thus moves 5116152 of the slab element 7 into the mounting sleeve 5 in front of the slab element 7 out of the mounting sleeve 5.

The drawings and the description related thereto are intended only to illustrate the idea of the invention. The details of the invention may vary within the scope of the claims. Thus, after the installation of the slab elements 7, it is not necessary to remove all the structures used in the installation. For example, the lip plates 9 may, if desired, be left on the slots. After installation of the slab elements 7, they rest on the primary beams 4, and thereby on the support pile 3. If the soil is such that there is no fear of its routing 10, the slab element 7 may also rest on the ground beneath it. However, if there is a possibility of frosting, it is advantageous to form the structure such that there is an empty space underneath the slab element 7. An empty space can be formed, for example, by the fact that the terracotta slab element 7 is formed thinner in its central part, i.e. concave at its lower part.

Further, after installation, it is also possible, for example by means of a jack, to lift the bed slab elements 7 upwards and to install bearings of, for example, neoprene rubber between their primary beams 4 and the slab slabs 7 at their ends. On the other hand, if desired, underground slab elements 7 may be excavated and thus be made, for example, an underpass. Further, in order to eliminate the problem of frosting, the slab element 7 may have a pre-attached thermal insulator, for example on the lower surface or •: ·: on the upper surface or both.

Instead of pushing, for example, the mounting sleeve 5 and the slab elements 7 can also be retracted, for example, before installing the mounting sleeve 5, the pull rods are fitted through the embankment and the "V mounting sleeve 5 is pulled in place by pulling jacks. Correspondingly, terracotta tiles may be • ;;; for the elements 7, adjust the tension rods and pull the floor slab elements 7 in position by means of tension jacks. For the slab elements 7, the tension rods can be pre-fitted inside the mounting sleeve 5, so that there is no need to install the tension rods separately for the slab elements 7: .i 30. The mounting bush 5 and pengerlaat-:, taelementti 7 can be installed through one of the embankment on either side of the embankment. any time. Thus, for example, the installation may be carried out alternately on different sides of the embankment, so that after the installation of one batten element 7, the installation sleeve 5 does not have to be transported back over the embankment 1, but installation 35 can be continued from the side 1 of the embankment '·: After installing the glaze element 7 is. For example, the rhythm of work 6,116,152 can be accelerated. Further, the solution is advantageous if, for example, at one point of the blade 1 there is an obstacle on the other side thereof, which would prevent the work, but still allows installation of the slab element 7 using the other side. In such a case, it may be necessary that no support beam 10 is used inside the mounting sleeve 5 and that the mounting sleeve 5 is retracted to the same side of the embankment 1 as it was installed through the embankment 1. On the other hand, the support beam 10 need not necessarily be uniform over the entire mounting sleeve 5, but may be formed of shorter parts. The mounting sleeve 5 is preferably symmetrical in the longitudinal direction, i.e. such that it does not have to be mounted always with the same end in front, but it can be mounted in the longitudinal direction in both directions. If an end plate is formed after the support beam 10, the support beam 10 is rotated so that when the support beam 10 is installed, the end plate is always at the end. In addition to the above-mentioned lateral displacement and height displacement, the slab tile elements 7 can also be moved longitudinally after removal of the mounting sleeve 5 after mounting on the primary beams 4, whereupon erroneous positions of the slab tile elements 7 can be eliminated. The mounting sleeve 5 may be used to support the floor slab element 7 through its embankment 1 and, for example, a support beam 10 may be used to retract the floor slab element 7. However, the mounting sleeve 5 does not necessarily have to be substantially *: ·: influencing the pulling or pushing of the slab element 7.
