The present invention relates to a piping member for a railway tunnel, and more particularly, to a piping member used for a drainage facility of a railway tunnel or a subway tunnel, in particular, providing a good drainage effect through an inclined structure and adopting a prefabricated installation structure. A piping member for railroad tunnels that provides field installation property.

Railway tunnels, particularly subway tunnels, are generally provided with a drainage system for collecting and draining various types of water introduced into the tunnel.

1 is a plan view showing an example of a conventional railway tunnel drainage facility, Figure 2 is a cross-sectional view showing an example of a conventional railway tunnel drainage facility.

In the illustrated drainage system, in a linear underground tunnel constructed by connecting a plurality of cylindrical segments 30, a drainage system is installed at a railway center side to collect water that is permeated or introduced into the tunnel.

In more detail, the sump 40 is installed in the concrete concrete 38 below the plurality of sleepers 36 supporting the rail 34. The sump 40 is formed in the shape of a groove having a narrower width than the rail 34 and extends along the rail direction. Such a sump 40 may be formed, for example, with dimensions of about 30 m in total length, 0.9 m in width, and 0.5 m in depth.

On the other hand, a water level sensor (not shown) is installed in the sump 40, and the first, second and third submersible pumps 42, 44, 46 are arranged, and the first and second submersible pumps 42, In the arrangement position of 44, the width of the sump 40 is formed to be narrowed by about 1/2.

In addition, one land pump 52 is disposed on the maintenance channel 50 formed slightly higher beside the rail 34. From the land pump 52, the absorption pipe 53 for suctioning the water in the sump 40 is extended. In addition, each of the pumps 42, 44, 46, 52 is connected with drain pipes 54a, 54b, 54c for draining to the sump of the adjacent station, respectively.

The number of such submersible pumps and land pumps is not limited to the illustrated numbers and may be arbitrarily modified as necessary.

The side concrete portions 38 on both sides of the rail 34 are provided with side openings 60 and 62 extending along the water collecting tank 40, and the side openings 64 are provided next to the maintenance source passage 50, respectively.

Water that seeps into or flows into the tunnel and collects in the side openings 60, 62 and 64 flows into the sump 40 through a plurality of transverse openings 66 and 68.

On the tunnel wall surface in the vicinity of the land pump 52, a control panel 70 for driving control of the first and second submersible pumps 42 and 44 and the land pump 52 is provided. On the other hand, a power source and a control unit for controlling the driving of the third submersible pump 46 are installed in an adjacent neighboring station, and are connected to the submersible pump 46 by wires extending in the tunnel.

Water that permeates or flows into the tunnel flows from the side openings (60, 62, 64) through the transverse openings (66, 68) into the sump (40) or from both ends of the sump (40).

When the water level in the sump 40 reaches a predetermined level and is detected by the water level sensor, at least one of the first submersible pump 42, the second submersible pump 44 or the land pump 52 is automatically operated, The water collected in the sump 40 is drained into a large sump provided in the basement of an adjacent station.

By the way, since the bottom surface of the conventional water tank of the drainage facility for railway tunnels is formed flat, there exists a problem that the water which flowed in inside does not flow easily to the water pump side, and does not collect.

When water in the sump cannot be collected and discharged in a short time, a humid atmosphere is maintained for a long time inside the railway tunnel, and such a humid atmosphere has a problem of adversely affecting durability of various equipment in the tunnel.

The present invention has been made in view of the above problems, and as a piping member used in the drainage facility of a railway tunnel or a subway tunnel, in particular, providing a good drainage effect through the inclined structure and adopting a prefabricated installation structure, excellent field installation It is an object of the present invention to provide a piping member for railway tunnels that provides the characteristics.

And side wall portion 320 to form both side walls of the sump; A bottom portion 310 which seals a bottom surface between the side wall portions 320 and is spaced apart from a lower end of the side wall portion 320 to have a predetermined height; A jaw portion 330 formed to extend outwardly from an upper end of both side wall portions 320 to a predetermined width; The upper pipe member 300 having the side wall part 320, the bottom part 310, and the jaw part 330 formed on both end surfaces, respectively, and an upper locking part 360 protruding to an upper side of the corresponding cross section. This is done, including.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

3 is a front view of a piping member according to an embodiment of the present invention, Figures 4a and 4b is a left and right side view of the piping member according to an embodiment of the present invention, Figure 5 is a piping member according to an embodiment of the present invention Perspective view.

A collection tank extends along the lengthwise direction between rails of the railway tunnel so that water flowing into or in the tunnel can be collected and drained. In this embodiment, such a sump is formed using a prefabricated piping member having an inclined bottom.

The piping member 100 seals the side wall portion 120 that forms both side walls of the sump and the bottom surface between the side wall portions 120, and the bottom portion 110 provided with an inclination angle of a predetermined angle along the longitudinal direction. Equipped. Water introduced into the piping member 100 by the inclination angle applied to the bottom 110 is easily flowed to the lower side of the inclination angle can be collected.

The jaw portion 130 extends outwardly from the upper end of both side wall portions 120 of the piping member 100 by a predetermined width. The jaw portion 130 is mounted on the upper side of the two-phase concrete (not shown) in which the water collecting tank is installed to support the load of the piping member 100, and the water flowing in from the concrete concrete side is smoothly connected to the piping member. (100) Allow it to flow inside.

On the other hand, the pipe member 100 is a plurality of connected to form a water collecting tank extending in the longitudinal direction, it is caught on both ends of each pipe member 100 so that the adjacent pipe member 100 can be connected firmly formed The addition is formed.

To this end, a lower locking portion 150 protrudes from an upper end surface of the inclination angle among both end surfaces formed by the side wall part 120, the bottom part 110, and the jaw part 130.

In addition, the upper end portion 160 of the cross section is formed to protrude to the upper side of the cross section of the cross-section of the cross section formed between the side wall portion 120, the bottom portion 110, the jaw portion 130.

More specifically, the left side of the piping member illustrated in FIG. 3 is connected to another piping member 100 having a lower bottom 110 height while the bottom 110 has the same inclined structure along the longitudinal direction. On the right side, the bottom 110 has the same inclined structure along the longitudinal direction while another piping member 100 having a higher bottom 110 height is connected.

At this time, the lower locking portion 150 formed on the right end surface (upper cross section of the inclination angle) of the piping member illustrated in FIG. 3 is mounted on the upper locking portion 160 of another piping member 100 positioned on the right side. Combined. In addition, the upper locking portion 160 formed on the left end surface (lower end surface of the inclination angle) of the piping member illustrated in FIG. 3 is mounted on the lower locking portion 150 of another piping member 100 positioned on the left side. Are combined sequentially.

By this coupling structure, each piping member 100 forms a solid connection state and forms a collection tank having a bottom surface having an inclined structure. In addition, since only the bottom 110 is inclined to each pipe member, and the side wall 120 is horizontal in a state where the top and bottom thereof are parallel, the pipe member itself may be kept horizontal when installed.
