Description

Bridge drainage structure {Construction for braining a bridge}

The present invention relates to a drainage structure of a bridge, and more particularly, to form a binding groove and a sloped circumferential surface of a predetermined length at the bottom of the binding groove, which are components of a conventional bridge drainage structure, respectively, and are connected to the water collecting pipe. The drainage pipe is formed by forming a fixed protrusion coupled to the binding groove of the collecting pipe and a cutout groove having a predetermined length so that the inlet of the drain pipe can be opened by an elastic force, and thus the drainage pipe coupled to the collecting pipe. Installation and dismantling can be facilitated, and in particular, the drainage pipe member is separated from the collection pipe member by the self-weight of the drain pipe member fixed to the collection pipe member, and the rainwater introduced from the collection pipe member is transferred to the drain pipe member. It relates to a bridge drainage structure to prevent the flow of rainwater between the separated collection pipe and the drain pipe without flowing.

In general, the bridge is provided with a drain for draining the water generated in the bridge top plate by rain or snow, the drain portion is composed of a collecting pipe installed in the vertical direction on the bridge top plate, and the drain pipe coupled with the collecting pipe.

The drainage configured as described above, the drain pipe 13 is inserted into the lower end of the collecting pipe 12 is installed in the net 11 in the tubular side in order to prevent foreign substances flowing in with the rain water, using the bolt 14 The water pipe 12 and the drain pipe 13 are to pass through the overlapping portion is fixed with a nut (15).

In addition, the extension drain pipe 21 connected to the drain pipe 13 to extend the pipe, the upper end is fixed to the bridge upper plate 60, the lower end by the support member 50 coupled to the extension drain pipe 21 It is fixed and supported, and the connection of the drain pipe 13 and the extended drain pipe 21 is performed by butt welding the end of the drain pipe 13 and the tip of the extended drain pipe 21, and performing two butt welds 13 ( 21) is connected as shown in FIG.

However, in the drainage coupling structure configured as described above, the collecting pipe 12 and the drain pipe 13 are fixed to each other by the bolt 14 and the nut 15, and the rainwater and the water collecting pipe 12 are fixed to each other. Along with the drawback that the clogging phenomenon of the water collecting pipe 12 may be generated while the fine particles are accumulated, when the bolt 14 is corroded, the drain pipe 13 is separated from the water collecting pipe 12 to fall. There was a big problem. In addition, since the collecting pipe 12 and the drain pipe 13 are fixed with the bolts 14 and the nuts 15, the installation and disassembly of the drainage part, that is, the collecting pipe 12 and the drain pipe 13, are performed. There was also a big problem that labor costs increased during maintenance and maintenance work.

In the case of the coupling structure of the drain pipe 13 and the extended drain pipe 21, the drain pipe 13 and the extended drain pipe 21 are connected to each other by butt welding. Corrosion and oxidation (22) shorten the service life of the pipe, and there is a big problem that the weld 22 is cracked and the drain pipe 13 and the extended drain pipe 21 are separated from each other.

In order to solve the above problems, the bridge drainage coupling structure of Utility Model Registration No. 188373, which was pre-registered on April 26, 2000, has been proposed. As shown in FIG. 80 is installed in the vertical direction and the water collecting pipe 31 formed with grooves 36 and 36a at the lower end, and the protrusion 35 is formed on the inner side thereof so that the protrusion 35 is the groove of the water collecting pipe 31. It consists of a drain pipe 32 is fitted in the 36 (36a) and coupled to the collecting pipe 31, the inner end of the drain pipe 32 in the vertical groove 36 formed in the vertical direction from the bottom of the collecting pipe 31 The drain pipe 32 is inserted into the water collecting pipe 31 so that the protrusion 35 formed therein is inserted therein, and then the water pipe 32 is rotated along the bending groove 36a of the water collecting pipe 31. The drain pipe 32 and the collecting pipe 31 are coupled to each other, in particular, even if the vibration is applied from the outside due to the weight of the drain pipe 32 It has the advantage (35) that is separated from the bending groove (36a).

However, in order to fix the drain pipe 32 to the collecting pipe 31, the protrusion 35 formed inside the tip of the drain pipe 32 must be rotated only when the drain pipe 32 is rotated. Inserted into 36a) has a big problem that the installation hassle, such that the drain pipe 32 is fixed to the water collecting pipe (31).

In addition, as described above, the protrusion 35 of the drain pipe 32 is inserted into the bending groove 36a of the water collecting pipe 31 as the drain pipe 32 rotates so that the drain pipe 32 is connected to the water collecting pipe ( 31, even if it is fixed to the long-term use, the projection 35 formed in the drain pipe 32 due to the weight of the drain pipe 32 is bent or broken, the water collecting pipe 31 and the drain pipe 32 are mutually coupled There is also a big problem that the rain water flows in between the separated collection pipe 31 and the drain pipe 32 without the rain water flowing from the collecting pipe 31 flows into the drain pipe 32 while being separated from each other.

The present invention devised to solve the conventional problems as described above, facilitates the installation and disassembly of the drain pipe coupled to the water collecting pipe, and at the same time by the weight of the drain pipe fixed to the water collecting pipe As described above, the drain pipe is separated from the water collecting pipe so that rainwater introduced from the water collecting pipe does not flow into the drain pipe, and the rainwater is prevented from flowing out between the separated water collecting pipe and the drain pipe.

In order to achieve the object of the present invention, in the conventional bridge drainage structure consisting of a collecting pipe installed on the bridge top plate for drainage and a drain pipe coupled to the collecting pipe;

A slanting circumferential surface is formed in which a diameter gradually narrows from a predetermined height of the water collecting pipe to a pipe end, and a water collecting pipe member having a binding groove formed in the entire circumferential outer surface of a predetermined height of the upper portion of the inclined circumferential surface, and the water collecting pipe member The bridge of the present invention consists of a drainage pipe member formed with a plurality of cutout grooves having a predetermined length so that the inlet portion can be easily opened by the elastic force on the outer side of the tube circumference so as to be fixed to the groove. It can be solved by the drainage structure, it will be described in detail with reference to the accompanying drawings.
