The present invention connects the drainage pipe and the drainage pipe when the drainage pipe is connected to the lower portion of the bridge to drain the rainwater and cleaning water generated on the bridge road to the outside of the bridge to drain the bridge, but the inside of the drainage pipe The present invention relates to a method of connecting a drain pipe by using a drain pipe connector that can be easily dismantled while easily disassembling the drain pipe connector that interconnects the drain pipe and the drain pipe when cleaning or replacing a broken drain pipe.

       In addition, by interconnecting adjacent drain pipes using rubber packing when interconnecting the drain pipe and the drain pipe, the rubber material of the rubber packing absorbs the amount of shaking within a certain range of the drain pipe during an earthquake, so that the seismic function can be provided at the same time.

       In general, drains connected to the bridge catchment port installed in the upper slab of the bridge may be installed in a stream, such as the lower part of the bridge in a straight line, but in the case of a bridge installed on the road in the downtown area, the drain pipe is installed in contact with the pier at the bottom of the bridge, Figure 1 As shown in the drawing, several pipes are connected to one drain pipe at the same time, or form a curved line and connect the drain pipes so that the lowermost part of the drain pipes is in contact with the road so that water generated in the bridge is drained through the drain hole of the bridge lower road.

       As described above, the drain pipes have various shapes in a straight line or in a curved line, and the drain pipes are interconnected.

       When the drain pipe is connected in a curved state, if foreign matters accumulate on the curved part, the inside of the drain pipe is blocked and water cannot be drained smoothly.In the periodically connected part, the connection part connecting the drain pipe is dismantled to clean the inside of the drain pipe. Again, to connect the connection of the drain pipe.

       The connection device for connecting the drain pipe for maintenance and management such as cleaning the inside of the drain pipe periodically is easy to fasten and dismantle, but the watertight drain pipe connection device is required.

       In addition, when the drain pipe is installed to the road surface under the bridge, when the drain pipe is destroyed, inspected or deformed by a vehicle or a person, and the role of the drain pipe becomes impossible, the drain pipe is replaced. When the drain pipe is installed as a new drain pipe, the drain pipe and the drain pipe are interconnected. The drain pipe connecting device is a fastening and disassembly is convenient, but the water pipe is required to be watertight.

       Another reason is that when the drain pipe is shaken within a certain range due to an earthquake or the like, the drain pipe connecting part absorbs a certain range of vibration by the elastic rubber material of the rubber packing of the drain pipe connecting device connecting the drain pipe and the drain pipe. There is a need for a drain pipe connecting device that can simultaneously have a seismic function to prevent breakage.

       It is the drain pipe connection device of the present invention that has been improved to include all the requirements that the connection device of the drain pipe as described above should have.

       Referring to the method for connecting the drain pipe using the drain pipe connection device of the present invention.

       In connecting the drain pipe and the drain pipe extending to the lower part of the bridge catchment port installed in the upper slab of the bridge to install the pipe to drain the water generated on the road surface to the lower bridge,

       In order to connect the drain pipe and the drain pipe, the outside of the drain pipe is connected to the leakage preventing louver ring at a predetermined distance from both ends of the drain pipe facing each other, and the both ends of the leak preventing bubbling ring are fastened to the fastener.

       The quick fastener is a body of a rubber-like rectangular parallelepiped, so that a plurality of through holes penetrating the body in the longitudinal direction of the body is formed.

       Insert both ends of the leak-proof louver ring in the plurality of through-holes installed in the body into the respective through-holes in different directions, and then pull out and release the ends of the leak-proof louver ring exposed in different directions to automatically drain the pipe. Leak prevention louver wound on the outside of the

       As described above, the rubber packing is covered to cover both ends of the drain port while being wrapped at the outside of the leak-proof louver fastened to both ends of the drain port so that both ends of the drain pipe are integrated by the rubber packing.

       The elastic rubber packing as described above is installed so as to surround the outside of the leak-proof louver ring to include both ends of the drain pipe.

       If it is installed so as to surround the leak-proof louver ring as described above, the rubber packing portion of the portion where the leak-proof louver is installed due to the elasticity of the rubber packing is to form a protrusion upward.

       Winding the leak-proof louver at both ends of the drain pipe as described above prevents water leakage to the outside by the leak-proof louver, even if water is generated at the connection portions facing both ends of the drain pipe. Rubber packing is pressed by the protrusion is formed so that the leak occurs in the drain pipe connection is between the leak-proof louver ring is fastened to both ends of the drain pipe to prevent the leakage progress.

       It is to install the joint band so as to completely wrap the rubber packing again on the outside of the rubber packing installed as described above, and to connect the drain pipe using a drain pipe connection device fastened by a plurality of fastening clips installed on the joint band.

       In other words, the leakage preventing louver is wound around both ends of the drain pipe of the connecting portion where the both ends of the drain pipe face each other. It is to connect the drain pipe with the drain pipe connector to be tightened once again by the band.

       Conventionally, the drain pipe is not satisfied with simply connecting the pipe by a band or a fastener, and thus it is not possible to play a role of the drain pipe due to a leak occurring at the connection part of the drain pipe.In the case of a city, when a pedestrian or a vehicle runs under the bridge, The risk of traffic accidents has always existed due to leaks generated at the connection of the installed drain pipe, causing inconvenience to the pedestrians or vehicles while walking or obstructing the driver's vision.

       In addition, in order to prevent the leakage of the drain pipe as described above, the maintenance of the drain pipe is frequently performed, there has been a problem of loss of cost, maintenance, and time required for maintenance.

The present invention wraps the leakage preventing louver at both ends of the drain pipe connecting the drain pipe to improve the problems as described above, and wrap the rubber packing on both ends of the drain pipe, and fastening the joint band thereon The rubber packing elasticity is prevented even if an earthquake occurs at the connection part of the drain pipe even during an earthquake, while making it easy to disassemble or quickly fasten the drainage pipe connection device to clean the inside of the drain pipe while preventing leaks generated in the connection part from leaking to the outside. It is a drain pipe connection method using a drain pipe connection device to have a seismic function at the same time to absorb the shake of a certain range to prevent damage to the drain pipe connection.

Referring to the configuration and operation of the present invention in detail with reference to the accompanying drawings as follows.

After completing step 4, fasten the joint band to the outside of the rubber packing connecting the drain pipe, and connect the drain pipe with the drain pipe connector connected with the fastening club. 6 is a view showing a cross section [A-A] connected by the drain pipe connection device of FIG. 5, and FIG. 7 is a view showing the "detailed cross section B" of FIG.

       Briefly summarizing the drain pipe connecting device 20 of the present invention, the leak-proof louver ring 21 is installed at both ends of the drain pipe 13, the leak-proof louver ring 21 is a rubber packing ( It is inserted into the through portions 41 on both sides of the 40 so that the ends of the drain pipe 13 are in contact with each other in the through portions 41, and the joint band 50 is fastened on the rubber packing 40.

       As described above, the drain pipe 13 is connected to each other by using the drainage pipe connecting device 20 as shown in FIG. 1 to install the pipe to drain rainwater or cleaning water generated on the road surface of the bridge.

       The process of installing the drainage pipe connection device 20 step by step is as follows.

       First, as shown in FIG. 2, a leakage preventing louver 21 made of any one of stainless steel wire or rubber coated stainless steel wire or PVC material is wound around a predetermined distance between both ends of the drain pipe 13 to be connected. To do that.

       In order to fasten the wound leak-proof louver 21 around the drain pipe 13, the leak-proof louver using a quick fastener 30 as shown in (b) or (c) of FIG. (21) to be fastened as shown in FIG.

       The quick fastener 30 is made of a rubber material constituting the body 31 of the rectangular parallelepiped, and a plurality of through holes 32 penetrating the body 31 is formed,

       Alternatively, the plurality of cylindrical bodies 33 are interconnected as rubber materials, and the through holes 32 are formed in the longitudinal direction of the cylindrical body 33.

       Referring to the method of fastening the leak-proof louver ring 21 using the quick fastener 30 with reference to Figure 3 (a),

       One end of the leak-proof louver ring 21 is inserted into the through hole 32 of the quick fastener 30, and the other end of the leak-proof louver ring 21 is the leak-proof louver ring 21. One end of the through hole 32 is not penetrated, but both ends of the leak-proof louver ring 21 is inserted into the plurality of through holes 32 in different directions.

       Pulling both ends of the leak-proof louver ring 21 inserted and inserted in different directions as described above, the rubber body body 31 is prevented from leaking in the through-hole 32 of the quick fastener 30. It is in close contact with the louver ring 21 so that it is no longer loosened.

       In another method, a plurality of grooves (not shown) are formed at regular intervals in the circumferential direction in the through hole 32.

       After passing both ends of the leak-proof louver ring 21 in the plurality of through-holes 32 of the fastening hole 30 in which the grooves are formed in different directions, pull both ends of the leak-proof louver ring 21, and then When placed, it may be fastened so that the groove formed in the through hole 32 is in close contact with and released by the frictional force generated in contact with the leakage preventing louver 21.

       On the contrary, in case of disassembling the leakage preventing louver ring 21 fastened by the quick fastener 30, both sides of the leakage preventing louver ring 21 are removed to remove the leakage preventing louver ring 21 inserted into the through hole 32. When pulled out from the leak-proof louver 21 is to break through the through hole 32 and the state surrounding the drain pipe 13 is dismantled.

       In other words, when tightening and releasing both ends of the leak-proof louver ring 21 in the opposite direction when tightening, and when releasing, when pulling the leak-proof louver ring 21 of the non-end portions of the fastening fastener 30 Both ends of the leakage prevention louver 21 from the through hole 32 are released to be released.

       At this time, if there is a groove in the through hole 32 or there is no groove, the same operation as described above can easily release and fasten the leakage preventing louver ring 21 so that it can be fastened and released quickly. This is to give convenience to management.

       As another reason, the leakage preventing louver 21 is wound around both ends of the drain pipe 13 so that the leaked water is discharged from the drain pipe 13 after the drain pipe 13 is interconnected. Leakage is set so that the leaked water exists between the water leak prevention louver 21 wound around a certain part on both ends of the drain pipe of the connecting portion facing both ends of the drain pipe 13 without leaking outside) This is to prevent further progress.

       In addition, as shown in (b) or (c) of FIG. 3, the form of the fastener is diversified to have a rectangular parallelepiped or cylindrical body connected to each other.

       The quick fastener 30 is diversified in order to select and use the quick fastener 30 to be installed depending on the diameter of the drain pipe 13.

       In the case where the diameter of the drain pipe 13 is large, the surface contacting the quick fastening port 30 becomes wider, so that both the fastening port 30 of the rectangular parallelepiped body 31 or the cylindrical body 33 can be used. 13) If the diameter of the small to be used as a quick fastener 30 of the cylindrical body (33).

       The reason is that the drain pipe 13 having a small diameter has a small curvature so that when the quick fastener 30 is installed along the outer circumferential surface of the drain pipe, the drain pipe 13 should be in close contact with the outer surface of the drain pipe 13. It is advantageous to use the quick fastener 30 having the same and also meets the object of the present invention where watertightness is required.

       However, it is not necessarily classified as described above may not selectively use the fastener 30.

       Next, when the leak-proof louver 21 is fastened to the both ends of the drain pipe 13 by the fastening fastener 30 as described above, the through-hole 41 is formed in the center as shown in Figure 4 (b) An end portion of the drain pipe 13 having the leakage preventing louver 21 fastened to both sides of the through part 41 of the rubber packing 40 by using the rubber packing 40 of the rubber shape as shown in FIG. Insert so that both ends of the drain pipe is in close contact with each other so that the drain pipes are interconnected.

       As described above, the leak prevention louver 21 is inserted into the through part 41 of the rubber packing 40 so that the drain pipe 13 is interconnected and the rubber packing surrounding the part where the leak prevention louver 21 is fastened. By the rubber material having elasticity of 40, the protruding portion 42 protruding by the thickness of the leak preventing louver 21 while being in close contact with the leak preventing louver 21 is formed.

       As described above, the rubber packing 40 tightly installs to surround the connection part of the drain pipe 13 while covering the leak preventing louver 21 and the leak preventing louver using the elasticity of the rubber, which is the material of the rubber packing 40. When the cover 21 is in close contact with each other, the leakage generated at the connecting portion is prevented from leaking to the outside by the leak preventing louver 21 as a primary, and the leakage preventing louver 21 is then wrapped while the connecting portion is wrapped. Water leaking by installing in a state in which the rubber packing 40 is in close contact with the outside of the rubber packing 40 as the leak-proof louver ring 21 and the rubber packing 40 in contact with the leak-proof louver ring 21 Due to the protruding protrusions 42, the water leaked to the outside is kept in a sealed state without further development.

       For another reason, even if the connecting portion of the drain pipe 13 is shaken within a certain range by an earthquake, the elastic portion of the rubber packing 40 surrounding the connecting portion absorbs a certain range of shaking by the elasticity, so that the connecting portion of the drain pipe 13 is broken or dislodged. It also has a seismic function to prevent the same.

       As another method, the watertight prevention louver 21 is not first fastened to both ends of the drain pipe 13 so that the parts facing both ends of the drain pipe 13 are covered with the rubber packing 40 so that the drain pipe 13 is first closed. After connection, the leakage preventing louver ring 21 at both ends of the drain pipe 13 on the installed rubber packing 40 may be connected by fastening fasteners (30).

       Even when the leakage preventing louver ring 21 is fastened on the rubber packing 40 as described above, the rubber of the rubber packing 40 is pressed by the leakage preventing louver 21 so that the drain pipe 13 and the rubber packing 40 come into close contact with each other. The effect of preventing the leakage of water generated in the connecting portion from further developing to the outside is the same as the effect generated when the rubber packing 40 is wrapped on the leakage preventing louver 21 at both ends of the drain pipe 13. will be.

       When the above operation is completed, as shown in Figure 5 to fasten the joint band 50 made of one of PVC material or stainless steel or iron material to wrap the rubber packing 40 on the outside of the rubber packing 40, the joint By fastening the fastening clip 51 attached to the band 50 to squeeze the rubber packing 40 from the outside of the rubber packing 40 so that the connection state of the connection is fixed to prevent the leakage of the water to progress, during maintenance and management Fastening and dismantling were made by using fastening clips.

       If the rubber packing 40 is pressed in the state in which the rubber packing 40 is pressed by the joint band 50 fastened to the outside of the rubber packing 40, the protrusion 42 of the rubber packing 40 in contact with the leak preventing louver 21 is provided. The joint band 50 is pressed more strongly, so that the gap can be completely sealed so that the water can leak to double the effect of preventing the leak.

       6 and 7 are all the above-mentioned process, that is, the leakage preventing louver ring (21) is wound around both ends of the drain pipe (13), fastening the rubber packing 40 thereon, fastening the joint band 50 thereon The cross section is shown in detail while showing the cross section of the sequence.

The drainage pipe connecting device is assembled and installed with a leakproof louver as a quick fastener, and the drainage rubber louver is covered with a tubular rubber packing thereon to cover the leakproof louver, and the fastening clip is released or fastened and released. It is a device that can be fastened with a joint band where possible, so that it can be fastened or disassembled by installing it as a whole.

The present invention wraps the leakage preventing louver on both ends of the drain pipe connecting the drain pipe, wrap the rubber packing on the both ends of the drain pipe, and fasten the joint band thereon to leak the leakage generated in the connection part It is possible to easily dismantle or quickly fasten the drainage pipe connection device to clean the inside of the drainage pipe, and absorbs a certain range of vibration by the elasticity of the rubber packing even if a wave occurs at the connection part of the drainage pipe during an earthquake. It is a drainage pipe connection method using a drainage pipe connection device with improved construction and economical efficiency to have a seismic function to prevent damage of the drainage pipe connection part at the same time.
