Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a floor drain pipe structure. Background Art

[0002] During the construction process, it takes a long period of decoration and renovation from the installation of pre-buried floor drains and water traps to the owner's move-in. During this period, floor drains are often blocked by construction waste due to improper protection measures for finished products. It is difficult to dredge the traditional floor drain inspection port for construction waste. After the cement mortar hardens, the internal construction waste needs to be removed from the inspection port or even the blocked drainage pipe needs to be replaced. After the house is delivered and during the fine decoration process, it is also easy to be blocked by floor tile mortar, shoveled wall waste, etc. At this time, dredging requires the agreement of the downstairs owner to dredge from the downstairs inspection port. During the dredging process, the garbage inside the floor drain can contaminate the finished decoration of the downstairs owner, thus causing a series of problems such as conflicts and compensation, and damaging neighborhood relations, which is not what the technicians in this field want to see.

[0003] In view of the above problems, the utility model discloses a floor drain pipe structure, which is characterized by comprising an inner pipe, an outer pipe, a connecting pipe and a drainage riser;

[0004] The inner tube is nested in the outer tube, and an inspection port is provided at the bottom of the outer tube. Floor drain bell mouths are provided at the tops of the inner tube and the outer tube, and the floor drain bell mouth of the inner tube is located above the floor drain bell mouth of the outer tube.

[0005] The inner tube and the outer tube are provided with drainage outlets on one side adjacent to the drainage riser, and a filter is provided at the drainage outlet of the inner tube. The two ends of the connecting tube are respectively connected to the drainage outlet of the outer tube and the drainage riser, and a water trap is provided in the middle of the connecting tube.

[0006] In some of the embodiments, an inspection port is provided at the bottom of the trap.

[0007] In some of the embodiments, a sealing ring is provided on the outer side of the drain port of the inner tube, and the thickness of the sealing ring is greater than the gap between the inner tube and the outer tube.

[0008] In some of the embodiments, the sealing ring is a rubber pad.

[0009] In some of the embodiments, a handle is provided on the inner tube.

[0010] In some embodiments, the inner tube and the outer tube are both circular tubes, and the difference between the inner diameter of the outer tube and the outer diameter of the inner tube is 1 to 5 mm.

[0011] In some embodiments, the filter screen is a galvanized steel wire screen.

[0012] In some of the embodiments, a cover plate is provided at the bell mouth of the floor drain of the inner tube.

[0013] Compared with the prior art, the above utility model has the following advantages or beneficial effects:

When the cover plate is damaged and construction waste flows into the floor drain, it will be stored at the bottom of the inner tube 3 and cannot flow into the water trap 41 of the connecting tube 4; and after the decoration construction is completed, the cover plate needs to be removed to check whether the floor drain pipe structure is unobstructed.

[0025] During the use of the above floor drain pipe structure, if there is construction waste, you only need to remove the inner pipe 3 to clean the waste. If the waste inside the inner pipe 3 cannot be cleaned, replace the inner pipe 3. If the inner pipe 3 cannot be removed from the top due to cement or other reasons, you can open the inspection port downstairs, push out the inner pipe 3 from the bottom, and clean it. The owner can remove the inner pipe 3 by himself, clean it regularly, and prevent the floor drain pipe structure from being blocked. If the filter is damaged, causing large foreign matter to flow into the water trap 41, the inspection port of the water trap 41 can be cleared and the inner pipe 3 can be replaced.
