Description

Technical Field

[0001] The utility model belongs to the technical field of municipal pipeline anti-seepage, and in particular relates to a municipal drainage pipeline anti-seepage structure. Background Art

[0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, commonly known as "sewer pipes". In engineering, they are usually called municipal drainage pipes. According to the current status of facilities under China's municipal roads, different pipelines are generally installed, such as electricity, communications, gas, water supply, drainage pipes, etc., and drainage pipes take into account measures for the separation of rain and sewage, that is, rainwater is generally discharged into nearby rivers, and sewage is discharged into sewage treatment plants, so municipal drainage pipes include two pipes: rainwater and sewage.

[0003] Municipal drainage pipes are usually laid underground, and the joints of municipal drainage pipes are usually sealed and anti-seepage with a single rubber pad. However, the service life of the rubber pad is relatively low, which leads to water seepage and poor sealing at the pipe joints when used for a long time. Once water seepage occurs in the municipal pipes, the seeped sewage can easily pollute the surrounding soil. On the other hand, the underground soil is eroded by sewage for a long time, and ground subsidence is prone to occur, causing damage to buildings and roads on the ground. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: A municipal drainage pipe anti-seepage structure, including a mounting pipe 1 and a connecting pipe 2, a contact head 3 is provided at the end of the mounting pipe 1, a rubber sealing ring 8 is fixedly connected to the outer wall of the contact head 3, a sealing head 4 is provided at the end of the connecting pipe 2, a sealing groove 5 corresponding to the rubber sealing ring 8 is provided on the sealing head 4, a locking ring 1 6 and a locking ring 2 7 are provided on both sides of the contact head 3 and the sealing head 4, a plug connector 9 is fixedly connected on both sides of the locking ring 1 6, a slide groove 10 is provided on the plug connector 9, a fixed bayonet 11 is provided on the inner side wall of the slide groove 10, an elastic self-locking mechanism is provided on the locking ring 2 7, the elastic self-locking mechanism includes mounting protrusions 12 arranged on both sides of the locking ring 2 7, and a sliding cavity 15 is provided on the inner side wall of the mounting protrusion 12.

[0023] As can be seen from the above, when in use, the operator can install the mounting tube 1 and the connecting tube 2 together. When the contact head 3 and the sealing head 4 are aligned with each other, the rubber sealing ring 8 on the contact head 3 will be aligned and inserted into the sealing groove 5 opened on the sealing head 4. When the rubber sealing ring 8 is inserted into the sealing groove 5, the connection between the mounting tube 1 and the connecting tube 2 will be sealed and prevented from seepage. After that, the operator can fix the mounting tube 1 and the connecting tube 2 through the multiple bolt holes on the contact head 3 and the sealing head 4.

[0024] Embodiment 2: The inner wall of the sliding cavity 15 is slidably connected with a pop-up member 14, the bottom width of the pop-up member 14 is adapted to the fixed bayonet 11, and a return spring 16 is fixedly connected to the outer wall of the pop-up member 14, and one end of the return spring 16 away from the pop-up member 14 is fixedly connected to the inner wall of the sliding cavity 15, and an outer sealing ring 13 is provided inside the locking ring 1 6 and the locking ring 2 7, and the outer sealing ring 13 is semicircularly arranged, and an inclined surface is provided at the end of the pop-up member 14, and an arc chamfer is provided at the end of the pop-up member 14 away from the inclined surface.

[0025] As can be seen from the above, after the installation tube 1 and the connecting tube 2 are fixedly installed, the operator can place the lock ring 1 6 and the lock ring 2 7 on the upper and lower sides of the contact head 3 and the packaging head 4 respectively for combined installation. When the lock ring 1 6 and the lock ring 2 7 are combined and installed, the installation protrusion 12 on the lock ring 2 7 will be aligned and inserted into the slide groove 10. During the insertion, the inner wall of the slide groove 10 will follow the contact inclined surface of the pop-up member 14 to squeeze and shrink the pop-up member 14 into the sliding cavity 15 so that it no longer blocks the insertion of the installation protrusion 12. When the installation protrusion 12 contacts the bottom of the slide groove 10, at this time, Under the elastic force of the reset spring 16, the pop-up piece 14 will pop out and insert into the fixed bayonet 11, fixing the installation protrusion 12 in the slide groove 10, thereby completing the installation of the lock ring 2 7 and the lock ring 1 6. When the lock ring 2 7 and the lock ring 1 6 are installed, the entire contact head 3 and the sealing head 4 will be covered, and the outer sealing ring 13 inside the lock ring 2 7 and the lock ring 1 6 will also press and seal the connection gap between the contact head 3 and the sealing head 4. Through two sealing and anti-seepage measures, it can effectively prevent sewage from seeping from the connection between the installation pipe 1 and the connecting pipe 2 when draining water.

[0026] It should be noted that when the outer sealing ring 13 inside the locking ring 1 6 and the locking ring 2 7 needs to be replaced due to the increase in usage time, the operator can press the pop-up piece 14 that has been pre-inserted into the fixed bayonet 11 on the outer side of the fixed bayonet 11 to make the pop-up piece 14 retract into the sliding cavity 15 again until it is free from the fixation of the fixed bayonet 11. At this time, the operator can pull the mounting protrusion 12 out of the slide groove 10 to complete the disassembly of the locking ring 1 6 and the locking ring 2 7. After the locking ring 1 6 and the locking ring 2 7 are disassembled, the outer sealing ring 13 inside them can be replaced.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
