Description

Technical Field

[0001] This utility model belongs to the field of water supply and drainage technology, specifically to an anti-clogging structure for building water supply and drainage. Background Technology

[0002] In existing buildings, sewer blockages and backflow have always been significant issues, directly impacting residents' living experience and the reputation of real estate developers. To address this problem, the following methods are currently employed: (1) The first floor has a single row, which solves the problem of drainage pipe blockage and flooding under certain circumstances; however, the site of drainage pipe blockage and flooding has shifted from the first floor to the second floor. (2) In the renovation of old residential areas, the most common method is to connect the drainage pipes of each household on the ground floor to the drainage well. The pipes are exposed outdoors, which are easily damaged and have a short lifespan. However, this method is for later renovation and is not suitable for existing new buildings. Summary of the Invention

[0003] This utility model provides an anti-clogging structure for building water supply and drainage, so as to prevent drainage pipes from becoming clogged and flooded.

[0004] A blockage-resistant structure for building water supply and drainage includes a drainage pipe, an overflow pipe, an H-shaped overflow pipe, an independent inspection well, and an outdoor inspection well; The H-shaped overflow pipe structure is as follows: both sides are pipes, and an inclined connecting pipe is connected in the middle; One side of the H-shaped overflow pipe is connected to the drain pipe, and the other side is connected to the overflow pipe. The inclined connecting pipe in the H-shaped overflow pipe connects upwards from the side where the drain pipe is located to the side where the overflow pipe is located; The drainage pipe is connected to an outdoor inspection well; from the outdoor inspection well, the wastewater is discharged into the municipal sewage network. The overflow pipe is connected to a separate inspection well.

[0005] Furthermore, the tilt angle of the inclined connecting pipe is 45°.

[0006] Furthermore, the H-shaped overflow pipe is connected to the drain pipe and the overflow pipe respectively through an external expansion pipe.

[0007] Furthermore, in the H-shaped overflow pipe, after being connected to the overflow pipe, a cover plate is installed on the upper side.

[0008] Furthermore, in the aforementioned drainage pipe, the pipe connected to the outdoor inspection well and the overflow pipe connected to the independent inspection well are installed at the same height.

[0009] The beneficial effects of this utility model are: This utility model provides an anti-clogging structure for building water supply and drainage. Its structure is rationally designed, incorporating an overflow pipe, an H-shaped overflow pipe, and an independent inspection well. During normal drainage without blockage, the overflow pipe and independent inspection well reduce the air pressure difference within the drainage pipe, facilitating smoother gravity-flow drainage. When the drainage pipe is blocked, the blocked wastewater flows through the H-shaped overflow pipe and the overflow pipe to the independent inspection well. Maintenance personnel can easily detect blockages by checking the independent inspection well, allowing for timely resolution. Attached Figure Description

Drainage pipe; 2. Overflow pipe; 3. H-type overflow pipe; 3.1. Inclined connecting pipe; 4. Independent inspection well; 5. Outdoor inspection well; 6. Municipal sewage pipe network; 7. External expansion pipe; 8. Cover plate. Detailed Implementation

[0011] The technical solution of the present invention will be further explained and illustrated below through specific embodiments. Example

[0012] This utility model provides an anti-clogging structure for building water supply and drainage, including a drainage pipe 1, an overflow pipe 2, an H-shaped overflow pipe 3, an independent inspection well 4, and an outdoor inspection well 5; The H-shaped overflow pipe 3 has the following structure: both sides are pipes, and an inclined connecting pipe 3.1 is connected in the middle; the inclined angle of the inclined connecting pipe 3.1 is 45°. One side of the H-shaped overflow pipe 3 is connected to the drain pipe 1, and the other side is connected to the overflow pipe 2; the H-shaped overflow pipe 3 is connected to the drain pipe 1 and the overflow pipe 2 respectively through the expansion pipe 7; after the H-shaped overflow pipe 3 is connected to the overflow pipe 2, a cover plate 8 is installed on the upper side to prevent the emission of sewage odor. The inclined connecting pipe 3.1 in the H-shaped overflow pipe 3 connects upward from the side where the drain pipe 1 is located to the side where the overflow pipe 2 is located; The drainage pipe 1 is connected to the outdoor inspection well 5; and the wastewater is discharged from the outdoor inspection well 5 to the municipal sewage pipe network 6. The overflow pipe 2 is connected to the independent inspection well 4.

[0013] In the drainage pipe 1, the pipe connected to the outdoor inspection well 5 and the overflow pipe 2 connected to the independent inspection well 4 are installed at the same height.

[0014] The working principle of this utility model: When the drainage pipe 1 is draining normally, it drains to the outdoor inspection well 5 and then enters the municipal sewage pipe network 6; the inclined connecting pipe 3.1 can play a role in preventing backflow; the overflow pipe 2 is connected to the outside through the independent inspection well 4, which reduces the air pressure difference caused by the drainage water column in the drainage pipe 1, and has the function of ventilating the drainage pipe and making the gravity flow drainage smoother. When drain pipe 1 becomes blocked, water can be drained to overflow pipe 2 via inclined connecting pipe 3.1, flowing out to independent inspection well 4. This allows maintenance personnel to promptly detect and address the blockage, buying time for unblocking the drainage pipeline and reducing the chance of sewage flooding the lowest-level users. If the amount of dirty water in independent inspection well 4 is small and detected in time, no treatment is necessary; it can simply air dry. If the blockage is large and only detected later, a vacuum truck should be used for treatment.
