Description

Permeable socket of conduit for drainage of tunnel}

The present invention is a socket for coupling the pipe connected to each other and the drain pipe for drainage in the tunnel and the ground water collected from the drain pipe to the center drain, in particular the insertion pipe is inserted into the pipe and the waterproof sheet pipe fixed to the insertion pipe The present invention relates to a socket for easily fixing a plurality of permeable drain pipes, as well as delivering groundwater collected from the drain pipes to the center drain without leakage.

Underground structures such as tunnels are absolutely affected by the performance and durability of the groundwater generated underground. In other words, if the groundwater is trapped on the back surface of the tunnel's surface structure, the groundwater's water pressure acts as an external pressure, causing water leakage on the ventilated surface, which not only damages the aesthetics but also affects the flow of traffic due to icicles in cold areas Gives.

In addition, by repeating freezing and melting of the porous concrete together with the groundwater, the weathering of the porous structure is promoted, thereby reducing durability.

Therefore, in order to solve the above problems, considerations for smooth drainage are required on the back side of the perforated concrete, and a method for installing a drain pipe on the back side of the perforated concrete is widely practiced to promote smooth drainage on the back side of the perforated concrete. It is becoming.

In addition, the drain pipe used in the prior art was used by forming a plurality of water passage holes in and out of the cylindrical tube wall made of polyethylene or vinyl chloride.

However, the above-described conventional drainage pipe is hard, and the bending is not easy and heavy, so the construction is bad, such as a large number of people must be arranged. In order to increase the amount of water, there is a problem in that the diameter needs to be increased.

Therefore, as in Utility Model Registration No. 201482, which was devised and registered by the applicant of the present invention, a plurality of drainage induction pipes consisting of an internal mesh pipe and an external permeable sheet were formed, thereby exhibiting lightness and excellent fluidity, thereby providing very high workability. Not only is it excellent, it has excellent water collection and drainage performance because it can exert water collection action over all areas, and has provided a drain pipe that can secure excellent durability.

However, the drain pipe made of a plurality of drain induction pipes as described above has a problem that the coupling of the connection pipe for delivering the groundwater collected from each drain pipe to one center drain is very difficult.

That is, in the conventional circular pipe, the connection pipe and the drain pipe are combined with each other by a T-shaped connector so that the collected ground water can be drained to the center drain side.

Permeable drainage pipes consisting of a plurality of drainage guide pipes described above cannot be mutually coupled by the aforementioned T-shaped connector.

Therefore, in order to use such a permeable drain pipe, there is an unreasonable point of drainage and coupling using an unstructured simple connector.

The present invention was devised to eliminate the problems as described above, by combining a waterproof sheet tube that can be bent freely on the flange of the flange formed insertion tube, by sewing a separate bundle band on both ends of the waterproof sheet tube,

Insert the waterproof sheet pipe into the end of the water-permeable drain pipe consisting of a plurality of drainage guide pipes, and fix it with a bundle band, and insert the connecting pipe into the insert pipe, thereby easily connecting the permeable drain pipe and the groundwater collected from the permeable drain pipe. It is an object of the present invention to provide a permeable drain pipe socket for tunnel drainage that leads to the center drain through the connecting pipe without leakage.

Hereinafter, preferred embodiments of the present invention will be described.

1 is an exploded perspective view of the socket of the present invention, Figure 2 is a side cross-sectional view of the socket of the present invention.

A cylindrical insertion tube 4 having a locking projection 1 formed at an inner lower portion and a flange 3 having a plurality of pin holes 2, 2 'formed thereon;

Coupling holes 5 are formed in the center, and bands 6 and 6 'are formed at both ends, and pin holes 2 and 2' of the flange 3 are formed at the periphery of the coupling holes 5 described above. Separately formed and formed a waterproof sheet tube (7) formed with a plurality of insertion holes (8, 8 ') corresponding to,

The insertion tube 4 is inserted into the coupling hole 5 of the waterproof sheet tube 7 from the inner side so that the pin hole 2, 2 ′ of the flange 3 and the insertion hole 8 of the waterproof sheet tube 7 ( 8 ') to match each other,

Insertion holes (8) (8 ') and pin holes (2) (2'), each of which has a locking member (9) formed at a lower end, and a locking member (11) (11 ') formed with a pressing part (10) formed at the upper end. By press fitting into) the flange 3 of the insertion pipe 4 and the waterproof seat tube 7 is configured to be coupled.

In the drawings, reference numeral 20 denotes a connecting pipe, 21 a center drain, and 22 a tunnel.

Referring to the operation of the present invention by the configuration as described above in more detail by the accompanying drawings as follows.

As shown in FIG. 2, the socket for connecting a drain pipe of the present invention is for coupling a drain pipe and a connection pipe formed of a plurality of drain guide pipes to each other.

The end of the connecting pipe 20 is inserted by the insertion pipe 4 having the locking jaw 1 formed therein, and the waterproof sheet pipe 7 which can be freely bent is provided with a plurality of drainage pipes as described above. (23) is inserted, the waterproof sheet pipe 7 is bent freely by a separate band (6, 6 ') for tightly fixing the permeable drain pipe (23) tightly.

In addition, the inserted insertion tube 4 and the waterproof sheet tube 7 include the flange 3 formed on the insertion tube 4 and the pinholes 2 and 2 'of the flange 3 and the waterproof sheet tube 7. It is fixed to each other by a separate locking member (11) (11 ') using the coupling hole 5 and the insertion hole (8) (8') of,

Insert the insertion tube (4) having the flange (3) formed inside the waterproof sheet tube (7), and then protrudes the insertion tube (4) into the coupling hole (5) of the waterproof sheet tube (7) flange (3) The pin hole (2) (2 ') and the insertion hole (8) (8') of the waterproof sheet tube 7 is to match each other.

In this state, when the locking members 11 and 11 'are pressed downward and inserted, the lower locking jaws 9 of the locking members 11 and 11' are inserted into the pin holes 2 and 2 'of the flange 3. The upper pressing part 10 is pressed against the periphery of the insertion hole 8, 8 ′ of the waterproof sheet tube 7 to a wider diameter so that the waterproof sheet tube 7 and the insertion tube ( The flange 3 of 4) is firmly fixed.

In this state, as shown in FIG. 3, the both ends of the tunnel 22 are tied to both ends of the water-permeable drainage pipe 23 in the longitudinal direction at regular intervals, and the insertion pipe 4 of the socket is connected in the transverse direction of the pipe 20 ) So that the connection pipe 20 is connected to the underground center drain 21, so that the groundwater collected from the permeable drain pipe 23 is transferred to the connection pipe 20 through the socket 20. ) Again sends the groundwater to the center drain 21 to discharge the groundwater collected by the center drain 21 to the outside.

Therefore, the present invention can be easily applied to the water permeable drain pipe 23 having an improved function, as well as the mutual coupling and connection by the bundle bands 6 and 6 '.

The permeable drainage pipe socket for tunnel drainage of the present invention as described above is inserted into the waterproof sheet pipe at the end of the permeable drainage pipe consisting of a plurality of drainage induction pipes and fixed with a band for banding. Easy connection of the drain pipe and groundwater collected from the permeable drain pipe is effective to guide the center drain through the connecting pipe without leakage.
