Technical Field

[0001] This utility model relates to the field of drainage structure technology, specifically a drainage structure for building construction projects. Background Technology

[0002] Laying drainage pipes is an essential part of house construction, as it allows sewage to be discharged into sewage wells through drainage structures.

[0003] However, drainage systems used in current building construction often become clogged, requiring workers to clear the blockages, which is very troublesome. Furthermore, the drainage pipes in existing building construction drainage structures are usually quite long, which means that if a pipe breaks, the entire pipe needs to be disassembled and replaced, resulting in a significant waste of materials.

A vertical drain pipe is installed in the vertical direction of the tee pipe through the flange. An inspection port is fixedly installed at one end of the vertical drain pipe, and a sealing cap is threaded to the outer end of the inspection port. An anti-blocking component is fixedly installed at one end of the sealing cap, and the anti-blocking component is located inside the vertical drain pipe.

[0006] The connection of the horizontal drain pipe is equipped with a connecting component, which includes an outer pipe. Flange 2 is provided on both the left and right sides of the outer pipe.

[0009] Preferably, several upwardly inclined elastic columns are uniformly fixedly installed on the outer wall of the other end of the elastic steel wire.

[0010] Preferably, the rubber sealing ring is frustum-shaped, with the larger diameter end of the rubber sealing ring fixed to the inner side wall of the second flange. A second sealing gasket is also fixedly installed on the inner side wall of the second flange, with the second sealing gasket located outside the rubber sealing ring.

[0011] Preferably, a plurality of round holes are evenly provided on the side wall of the second flange, and a tie rod is inserted between the two second flanges.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a drainage structure for building construction, comprising: a tee pipe 1, with flanges 4 fixedly installed at all three ends of the tee pipe 1; horizontal drain pipes 2 connected to both ends of the tee pipe 1 via flanges 4; vertical drain pipes 3 installed on the tee pipe 1 via flanges 4; flanges 4 fixedly installed at one end of both the horizontal drain pipes 2 and the vertical drain pipes 3 connected to the tee pipe 1; a sealing gasket 5 installed between the two flanges 4; and the two flanges 4 are fixed by bolts, thereby sealingly connecting the horizontal drain pipes 2 and 3 to the tee pipe 1.

[0022] A maintenance port 6 is fixedly installed at one end of the vertical drain pipe 3. An extended external threaded pipe is installed at the outer end of the maintenance port 6. A sealing cap 7 is threadedly connected to the maintenance port 6 through the external threaded pipe. The sealing cap 7 seals the maintenance port 6. When maintenance is required on the vertical drain pipe 3, the sealing cap 7 can be opened. An anti-clogging component is fixedly installed at one end of the sealing cap 7. The anti-clogging component is located inside the vertical drain pipe 3 and includes an elastic steel wire 8. One end of the elastic steel wire 8 is fixed to the inner end of the sealing cap 7, and the other end of the elastic steel wire 8... Insert the elastic steel wire 8 into the vertical drain pipe 3 through the inspection port 6. Several upwardly inclined elastic columns 9 are evenly fixed on the outer wall of the other end of the elastic steel wire 8. When sewage flows down through the vertical drain pipe 3, long hairs or filamentous foreign objects will be caught on the outer wall of the elastic columns 9, preventing them from flowing into the horizontal drain pipe 2 and causing blockage. It is only necessary to unscrew the sealing cap 7 periodically, pull the elastic steel wire 8 and elastic columns 9 out of the outer end of the vertical drain pipe 3 for cleaning, and then insert them back into the vertical drain pipe 3 after cleaning.

[0023] A connecting component is provided at the connection of the horizontal drain pipe 2. The connecting component includes an outer pipe 10. Flanges 11 are provided on both the left and right sides of the outer pipe 10. The diameter of the outer pipe 10 is larger than the diameter of the horizontal drain pipe 2. When it is necessary to connect the two horizontal drain pipes 2 or to repair a damaged horizontal drain pipe 2, the damaged part is cut and the outer pipe 10 is placed between the two sections of the horizontal drain pipe 2. The length of the outer pipe 10 is greater than the length of the gap between the horizontal drain pipes 2. Both ends of the outer pipe 10 are fitted onto the outer ends of the horizontal drain pipe 2. The two flanges 11 are respectively fitted onto the outer wall of the connection of the two horizontal drain pipes 2. The flanges 11 and the outer pipe 10 are sealed and connected by a rubber sealing ring 13.

[0024] The rubber sealing ring 13 is frustoconical in shape. The larger diameter end of the rubber sealing ring 13 is fixed to the inner side wall of the second flange 11. A second sealing gasket 12 is also fixedly installed on the inner side wall of the second flange 11, located outside the rubber sealing ring 13. Several round holes 14 are evenly distributed on the side wall of the second flange 11. A tie rod 15 is inserted between the two second flanges 11. The left and right ends of the tie rod 15 pass through the round holes 14 on the two second flanges 11 respectively and are threaded together. Adjusting nuts 16 are tightened repeatedly on both ends of the pull screw 15. When the adjusting nuts 16 are tightened, the rubber sealing ring 13 is inserted between the outer pipe 10 and the transverse drainage pipe 2 by squeezing itself. The upper and lower ends of the rubber sealing ring 13 are in close contact with the inner wall of the outer pipe 10 and the outer wall of the transverse drainage pipe 2, respectively. The sealing washer 12 is in close contact with the outer end of the outer pipe 10. Then, the soil at the connection is backfilled and compacted, thereby sealing the outer pipe 10 between the two transverse drainage pipes 2.

[0025] When this device is in operation, an anti-clogging component is installed at the inspection port 6 of the vertical drain pipe 3. When connecting two horizontal drain pipes 2 or repairing a damaged horizontal drain pipe 2, the damaged part is cut, and the outer pipe 10 is placed between the two horizontal drain pipes 2. Both ends of the outer pipe 10 are fitted onto the outer ends of the horizontal drain pipes 2. Two flanges 11 are fitted onto the outer walls of the connection points of the two horizontal drain pipes 2. The left and right ends of the tie rod 15 pass through the round holes 14 on the two flanges 11 and are threaded with adjusting nuts 16. When the adjusting nuts 16 are tightened, the rubber sealing ring 13 is inserted between the outer pipe 10 and the horizontal drain pipe 2 by squeezing itself. The upper and lower ends of the rubber sealing ring 13 are in close contact with the inner wall of the outer pipe 10 and the outer wall of the horizontal drain pipe 2, respectively, and the sealing gasket 12 is in close contact with the outer end of the outer pipe 10, thereby sealing the outer pipe 10 between the two horizontal drain pipes 2, which facilitates the connection or repair of the pipes.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
