PROCEDURE FOR ESTABLISHING A PASSAGE AT THE LEVEL CROSSING OF A RAILWAY OR TRAMWAY AND A ROAD; AS WELL AS A COVER AND PROTECTION ELEMENT FOR IMPLEMENTING THE PROCEDURE

The invention relates to a method for the establishment of a passage to be created at a level crossing of a railway or electric railway track and a road, as well as a cover-protection element for implementing the method.

At-grade road-rail crossings are critical locations for both traffic lanes. The construction of intersections on both tracks may require the stopping of traffic for longer or shorter periods of time, which, especially due to the sudden increase in road traffic, the increase in speed and axle loads, naturally represents a serious problem, to eliminate which high-load and long-life u.n. Edilon-type railway crossings, which contain flexible bedding and vibration-damped rails glued in concrete troughs formed in the prefabricated reinforced concrete large panels along the length of the railway track.

In the case of this type of crossings, track construction can be done in stages, however, the gluing operation of the rails requires a complete road closure and traffic diversion for up to a day.

On sections of the track where the topography or traffic conditions do not allow a complete road closure, only small elements ft fa ft ft

It is possible to use SZTNH-100347839 structure or asphalt pavement. However, such pavements can withstand the increasing road load only to a limited extent, and they need to be renovated every few years.

The task to be solved with the invention is the construction of the crossing in one or more phases at level crossings between a railway or electric railway and a road, especially a public road, in such a way that continuous traffic can be ensured during the construction with variable direction, guarded or controlled light signal control, including the immediate stopping of vehicles arriving with distinctive signs also its passage.

The basis of the invention is the realization that by using the large-panel Edilon structure mentioned in the introduction, a mobile, temporary, load-bearing cover-protection element designed for the duration of the placement and gluing of the rails, which fits into the trough of the large panel, can be raised, lowered and removed from it, can be flawlessly secured in the intersection continuity of road traffic.

Based on this recognition, we solved the set task with a process for establishing crossings to be created at the crossing of a railway or electric railway track and a road, according to the invention, during which at least two prefabricated reinforced concrete panels containing troughs for accommodating rails are installed on the track of the road, the IN 8* 4« We glued rails into W fi troughs, and which process is typical that

- a first panel and a second panel are installed on the track of the road, in such a way that the troughs in them fall in line with each other;

- after the installation of the first panel has already taken place, its troughs are covered with temporary mobile cover-protection elements suitable for carrying the vehicle load, and with this we enable (road) vehicle traffic transverse to the rails, while we continue the installation of the second panel;

- after the second panel has been installed, the protective cover elements covering the troughs of the first panel located in the traffic lane ensuring vehicle traffic are raised above the troughs at a distance, and their position is secured with washers, especially washer plates, resting on the surface of the first panel, in such a way that the vehicle traffic continue undisturbed in the traffic lane;

- pull the rails into the troughs of the first and second panels located in front of and behind each other, which are in a line, as well as, where appropriate, the troughs that are at least partially covered by the cover protection element, and fill the free troughs around the rails in them with adhesive material, while the cover-protection elements containing the let the traffic flow in the lane;

- after solidification of the adhesive material filled in the free-standing troughs, this traffic lane is handed over to traffic;

- and in the other lane, we remove the covering and protective elements above the troughs, the troughs are completely filled with adhesive, and after it solidifies, this traffic lane is also handed over to traffic.

The cover-protection element that can be used for the implementation of the method contains a cover located above the trough, and this cover-protection element is characterized by the fact that the cover has legs that extend downwards, are located at a lateral distance from each other, and fit into the trough, and that the cover extends laterally from these legs in two directions, the legs in its position in the trough, it has edges that lie on the surface of the first or second panel.

The invention will be described in detail below on the basis of the attached drawings, which on the one hand show the operational steps of the method, and on the other hand contain an advantageous embodiment of the cover-protective element.

Figure 17 shows the finished passage in a perspective view from above.

In Figure 1, the location of the crossing to be created is shown in a schematic perspective view, the road traffic lane is marked with reference number 1. In the state according to Figure 1, in the railway traffic lane 2 to be established, a highlighted earthwork mirror 3 indicates the beginning of the - crossing - works for the construction of the intersection, the work can continue undisturbed in the areas closed to 4 traffic.

The length h of the left-hand part la of the first panel I of the well-known, prefabricated reinforced concrete panel I shown in Figure 2 is smaller than the length H of part Ib, and the height mi marked in Figure 3 is equal to the total height M of the first panel I 5 for accommodating the rails not shown here value reduced by the depth of troughs m. thus, the rails that go into the troughs 5, which run along the part Ib of the first panel I, can rest on the surface of the part la of the first panel I. As shown in Figure 3, the upper edges of the troughs 5 are provided with protective elements 5a formed by angle steels.

The first panel I of Figs. 2 and 3 is shown in Figs. 4 and 4a. Figure 6 is placed on the ready-made substructure, which is leveled in a known manner, on the laying beams 7, and then the prefabricated wooden ft wooden ft ft reinforced concrete panel intended for the first transition section (not shown ®) is installed in part la of panel I, which is also the first panel is concreted through the pipes placed in them (not shown) under the laying beams 7 and on both sides; this concrete is designated as reference number 7a in Figure 4. The 4a. the footing beams of the railway track 8 are also shown in Fig.

The concrete 7a surrounding the first panel I at the bottom and on both sides, e.g. after it has partially solidified for a day, the 5 troughs extending in part Ib of the first panel I are covered as shown in Figures 5 and 6, 6a and 6b. For this, two by two, e.g. approx. We use a 2.0 m long cover-protective element 9, also shown in the larger-scale perspective drawing in Figure 6, whose width between the outer surfaces of the legs 10 formed by angle steels that can be slid into the trough 5, shown in Figure 6a, is slightly smaller than the width 5 width of trough S (Fig. 6). The cover-protective element 9 is on the upper side of the horizontal stem 10a of the legs 10, e.g. fixed by welding, and after sliding the vertical legs 10b of the cover protection element 9 into the trough 5, it rests on the upper surface of the first panel I with its edge parts 11a, 11b extending beyond the trough 5 on both sides. THE

Fig. 6 shows the phase of placing the cover-protection elements 9 directly into the troughs 5, while Fig. 6b. as can be seen in section in figure 8 - the cover-protective elements 9 are already in place without displacement, and as you can see, the second panel II is already in place here, the installation process of which is described in figures 7-9. with reference to figures.

According to Figures 7 and 8, the troughs 5 of the first panel I are covered by cover protection elements 9, the road traffic has been diverted here, and it flows undisturbed in this traffic lane, while on the other side, with the second panel II, we carry out the installation operations that the It has already been described in relation to the first panel I, that is, on the finished substructure 6, the laying beams 7 (Figure 9) are placed, and the second panel II is placed on them (as well as the transitional panel, not shown), and filled with concrete 7a through the pipes in them the space below them, which 7a concrete also surrounds the second panel II from the sides. The 5 troughs of the first panel I and the second panel II are in line, so I can draw them into the rails of the railway track.

However, before performing this operation, 10, 11 and 11a. as shown in the figures, in order that the passing traffic does not disturb the track control and the pouring of the troughs 5 with adhesive material, after placing the rails, we lift the cover-protective elements 9 from the troughs 5 of the first panel I and put them back in such a way that the 11 under the edges 11a of the cover extending to both sides, a washer plate 12 of thickness v is fitted, which is located without movement between the upper surface of the first panel I and the lower surface of the edges 11a even when traffic is taking place on this elevated section of the roadway containing the cover protection elements 9. In Fig. 11, the e.g. made of rubber sheet 2 cm thick 12 IN 1% 11*4 M W washers are attached to the flanges 11a. Fig. 11 shows the situation immediately before the sliding of the cover-protective element 9 into the trough 5, while Fig. 11a. figure shows the situation when the cover 11 of the cover-protection elements 9 extends above the upper plane of the troughs 5 by a distance v. The washer 12 can be a piece of board or any other load-bearing material, and it can also be placed on the surface of the first panel I before sliding the cover-protection element 9 into the trough 5.

The next operation of the method according to the invention is the pulling of the rails 13 under the raised trough protection and also extending to the second panel II into the troughs 5, as shown in Figs. 12, 13, and 13a. illustrated with figures. At that time, as long as traffic can flow undisturbed in the lane of the first panel I, the troughs 5 of the second panel II, with the rails 13 in them, are free and can be conveniently poured with adhesive, but the troughs 5 of the first panel I can also be poured under the raised cover protection elements 9 without problems.

In the state according to Figures 14 and 15, the adhesive material surrounding the rails 13 in the troughs 5 of the second panel II has already solidified, so now the lane containing the second panel II can be handed over to traffic. As can be seen in the left part of Fig. 14, the cover protection elements 9 have already been removed from the troughs 5 of the first panel I and the troughs 5 are ready for full w irt with adhesive 13

CN for their filling, which could have already started simultaneously with the pouring of the troughs of the second panel II. After that, their cross-section corresponds to that shown in Figure 15, which is ideally the commercially available EDILON synthetic resin adhesive. The last phase of the construction of the passage is shown in Fig. 16 in a top view, and the finished passage 15 is shown in perspective in Fig. 17.

The advantage of the invention is that it enables the construction of crossings at level crossings of railway and road tracks in such a way that road traffic does not have to be stopped or diverted in the meantime.

The invention is, of course, not limited to the implementation of the method detailed above, or to the illustrated and described embodiment of the cover-protective element, but can be implemented in a variety of ways within the scope of protection defined by the claims.
