Description

Technical Field

[0001] This utility model belongs to the technical field of urban sewage drainage facilities, specifically relating to an urban sewage pipe with an added rubber lining. Background Technology

[0002] Sewage pipes used for drainage are important components of urban sewage drainage facilities. Urban sewage pipes can be made of concrete, metal or plastic. Sewage pipes are generally fixed in the soil. During long-term use, sewage flows in the sewage pipes to meet the needs of urban sewage discharge.

[0003] During long-term use, some sewage pipes have rubber linings added to their inner walls to prevent sewage from looking down into the pipes. However, the sewage pipes and the lining pipes are usually fixed by adhesive or interference fit. Under long-term water erosion, they are prone to loosening and displacement, which reduces the sealing between the sewage pipes and the lining pipes and causes the sewage pipes to corrode. There is no design to limit or prevent the lining pipe ends on the sewage pipes, which needs to be improved.

[0004] Existing sewage pipes lack design features to limit and prevent detachment of the inner lining pipe ends during installation. To address this, this application proposes a new type of urban sewage pipe with an added rubber lining. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a city sewage pipe with an added rubber liner, including a sewage pipe body 1, with an inner liner pipe 4 installed inside the sewage pipe body 1. The sewage pipe body 1 transports urban sewage, and the inner liner pipe 4 is used to separate the sewage pipe body 1 from the sewage, preventing the sewage from corroding the sewage pipe body 1 under long-term sewage discharge and increasing the service life of the sewage pipe. The sewage pipe body 1 has pipe lips 11 at both ends, and the pipe lips 11 have screw holes for easy bolt penetration. The anti-detachment component includes an anti-movement pipe 5 installed on the inner wall of the sewage pipe body 1 and a reinforcing round pipe 6 that is interference-fitted with the inner liner pipe 4 and the anti-movement pipe 5. The end face of the anti-movement pipe 5 fits against the end face of the inner liner pipe 4, and the anti-movement pipe 5 restricts the end of the inner liner pipe 4. When both ends are restricted, the inner liner pipe 4 is prevented from displaced under the action of sewage flushing force. The outer and inner surfaces of the reinforcing round pipe 6 are respectively provided with integral injection molding. The outer convex ring 61 and the inner convex ring 62 are formed. The outer convex ring 61 is embedded inside the corresponding anti-movement pipe 5 and inner lining pipe 4 to further limit the anti-movement pipe 5 and inner lining pipe 4. The inner convex ring 62 is used to limit the covering round pipe 7 to achieve the purpose of positioning the covering round pipe 7 and ensuring the accurate installation of the covering round pipe 7. The reinforcement component includes the covering round pipe 7 that matches the end of the inner lining pipe 4 and the inner surface of the reinforcement round pipe 6, and the fixing ring 2 that is fixedly connected to the pipe lip 11. The covering round pipe 7 covers the reinforcement round pipe 6. Under the double-layer sealing design of the reinforcement round pipe 6 and the covering round pipe 7, the purpose of sealing the joint surface of the anti-movement pipe 5 and the inner lining pipe 4 is achieved. The end of the covering round pipe 7 is provided with a guide ring 71, which plays the role of guiding sewage. The fixing ring 2 is provided with a blocking ring 21, which limits the end of the covering round pipe 7 and makes the installation of the covering round pipe 7 stable. The guide ring 71 on the covering round pipe 7 is fixed to the inner lining pipe 4 by adhesive.

[0027] In this embodiment, the outer diameter of the inner lining pipe 4 is the same as the inner diameter of the sewage pipe body 1. The inner diameter and outer diameter of the inner lining pipe 4 and the anti-movement pipe 5 are the same, which makes it easy for the inner lining pipe 4 and the anti-movement pipe 5 to be installed inside the sewage pipe body 1.

[0028] In this embodiment, annular grooves that mate with corresponding external convex rings 61 are provided on the inner surfaces of the inner lining pipe 4 and the anti-movement pipe 5. The annular grooves are trapezoidal rings that are narrow at one end and wide at the other end. The cross-section of the external convex ring 61 is an isosceles trapezoid, and the cross-section of the internal convex ring 62 is rectangular. When the reinforcing round pipe 6 is installed, the external convex ring 61 is embedded inside the corresponding anti-movement pipe 5 and the inner lining pipe 4, thereby further limiting the anti-movement pipe 5 and the inner lining pipe 4. The internal convex ring 62, in conjunction with the inner lining pipe 4 and the anti-movement pipe 5, also serves as a seal.

[0029] In this embodiment, the outer surface of the covering tube 7 is provided with an annular groove a that mates with the inner convex ring 62. The cross-section of the annular guide ring 71 is a right triangle. The inner convex ring 62 is used to limit the covering tube 7, thereby achieving the purpose of positioning the covering tube 7 and ensuring the accurate installation of the covering tube 7.

[0030] In this embodiment, a reinforcing rib ring 8 is provided between the shielding ring 21 and the covering tube 7. The reinforcing rib ring 8 is embedded inside the covering tube 7. The covering tube 7 is made of corrosion-resistant stainless steel. The reinforcing rib ring 8 serves to support the end of the covering tube 7. The covering tube 7 supports and reinforces the end of the covering tube 7. A concave annular groove b that mates with the reinforcing rib ring 8 is provided on the inner surface of one end of the covering tube 7. Locking bolts 3 pass through the pipe lip 11 and the fixing ring 2. Under the reinforcement of the locking bolts 3, the fixing ring 2 and the pipe lip 11 are firmly connected.

[0031] Working principle and usage process of this utility model:

[0032] When an inner lining pipe 4 is added inside the main body of the sewage pipe 1, the inner lining pipe 4 is used to separate the main body of the sewage pipe 1 from the sewage, so as to prevent the sewage from corroding the main body of the sewage pipe 1 under long-term sewage discharge.

[0033] The end face of the anti-movement pipe 5 is attached to the end face of the inner lining pipe 4. The anti-movement pipe 5 restricts the end of the inner lining pipe 4. With both ends restricted, the inner lining pipe 4 is prevented from shifting under the action of sewage flushing force.

[0034] The reinforcing round pipe 6 is installed and matches the inner surface of the anti-movement pipe 5 and the inner lining pipe 4. The outer convex ring 61 is embedded in the interior of the corresponding anti-movement pipe 5 and inner lining pipe 4 to further limit the anti-movement pipe 5 and inner lining pipe 4.

[0035] The inner convex ring 62 is used to limit the installation of the cover pipe 7, so as to position the cover pipe 7 and ensure the accurate installation of the cover pipe 7. With the double-layer sealing design of the reinforced pipe 6 and the cover pipe 7, the joint surface of the anti-movement pipe 5 and the inner lining pipe 4 is sealed.

[0036] The reinforcing rib ring 8 is embedded inside the covering round tube 7, and the reinforcing rib ring 8 serves to support the end of the covering round tube 7;

[0037] The locking bolt 3 strengthens the connection between the fixing ring 2 and the pipe lip 11, thereby reinforcing the covering round pipe 7.

[0038] In summary: the sewage pipe has a design to limit and prevent the end of the inner lining pipe 4 from falling off. The anti-movement pipe 5 limits the end of the inner lining pipe 4 to prevent the inner lining pipe 4 from shifting under the force of sewage flushing. The reinforcing round pipe 6 is installed and limits the anti-movement pipe 5 and the inner lining pipe 4. With the double-layer sealing design of the reinforcing round pipe 6 and the covering round pipe 7, the anti-movement pipe 5 and the inner lining pipe 4 are fixed and sealed. The fixing ring 2 and the pipe lip 11 fix and reinforce the covering round pipe 7.

[0039] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
