Abstract

Provided are a rapid renewal rail turnout using a modular panel temporarily supporting a straight stock rail and a construction method thereof. In regard to a turnout installed to connect an existing track with a new track such that a track can be additionally constructed for a currently running subway, in a confined basement space, a modular panel is used to sequentially install turnouts within a nighttime train running cutoff period of several days, and, accordingly, the turnouts can be installed without causing a disturbance to daytime train running. Moreover, a temporary track skeleton supporter for opening a straight stock rail is used to form a predetermined separation space between the modular panel and a temporary rail coupler, thereby preventing vibrations or loads from being delivered to the modular panel by the running of a train during the curing of charging concrete. Moreover, the temporary track skeleton supporter is installed on the modular panel to temporarily open the straight stock rail, thereby preventing a halt in the running of a train during a train running time.

RAPID RENEWAL RAIL TURNOUT USING MODULE TYPE PANEL FOR SUPPORTING STRAIGHT STOCK RAIL TEMPORARY, AND CONSTRUCTION METHOD FOR THE SAME}

The present invention relates to a rapid refurbishment rail junction, and more particularly, in a junction installed for connection between an existing line and a new line so that a new line can be additionally established in a currently running subway, using a modular panel for several days It relates to a quick-change rail junction using a modular panel that temporarily supports a straight basic rail, which can sequentially install a junction within the night train operation cut-off time of , and a construction method therefor.

In general, in the stop section, a track facility installed at a branch point to branch from one track to another, such as changing the course from the main line to the side line, is called a junction, and changing the direction of such a junction is called a track changer. .

At this time, the junction system of the railroad rail is fixed as such that a single track composed of a pair of rails can be separated into two tracks so that a running train can select one of the two tracks to run. It consists of a rail and a tongue rail. In addition, the branching machine is composed of a point part for selecting which line to enter, a crossing part where gauge lines (rails) intersect, and a lead part formed between the rear end of the point part and the front end of the crossing part.

1 is a view for explaining the configuration of a general rail branching machine.

As shown in Fig. 1, basically, the rail branching machine includes a point portion that allows the straight and curved tongue rails to move in contact with or spaced apart from the straight and curved basic rails; a lead part connected to the next crossing part while the straight lead rail and the curved lead rail connected to the straight tongue rail and the curved tongue rail are gradually separated from the straight basic rail and the curved basic rail; and a crossing part that is completely separated while the two railroads intersect.

Specifically, in such a rail branch, when one track is split in two directions, a basic rail is installed on a straight side of the track, and a main rail is extended and installed on the basic rail in a straight line. The tongue rail connected to the basic rail has a certain curved angle and is sharply processed and installed, and the lead rail is connected to the tongue rail.

On the other hand, FIG. 2 is a view showing a common mold type modular branching machine, in which a) of FIG. 2 shows the shape of a common mold type modular branching machine, and FIG. 2b) is a photograph showing a construction example.

As shown in a) and b) of FIG. 2, the common mold type modular taper unifies the mold specifications to manufacture a common mold for each branching machine number, and has the advantages of low mold manufacturing cost and simplification of the mold. , the panel price increases according to the loss rate, and there are disadvantages in that it is necessary to manufacture and manage a matrix for each number.

3 is a view showing an individual molded modular branching machine, in which a) of FIG. 3 shows the shape of an individually molded modular branching machine, and FIG. 3b) is a photograph showing a construction example.

As shown in a) and b) of FIG. 3, the individual mold type modular taper diversifies the mold size to manufacture individual molds for each count, and it is easy to manufacture panels for each taper, and the price and loss rate can be reduced. However, there are disadvantages in that the mold production cost is high and it is necessary to secure a mold storage space.

4 is a view showing an individual sleeper-type modular turn-off machine. FIG. 4 a) shows the shape of an individual sleeper-type modular tap-off machine, and FIG. 4 b) is a photograph showing a construction example.

As shown in a) and b) of Fig. 4, the individual sleeper modular turn-off machine manufactures a wide sleeper-type panel and has the advantage of being able to manufacture with the existing PC sleeper type and minimizing the price, but it is linear when installed. The disadvantage is that the adjustment work time increases.

On the other hand, there is still no technology for installing an additional branching machine on a concrete roadway at home and abroad. For example, there are overseas cases where modular panels are used without using sleepers for branching machines when installing new ships on new ships, but the common mold type has the advantage of reducing the production cost because the cost of the mold for manufacturing the modular panel is high. There is a disadvantage in that the mold is installed to an unnecessary area.
