Description

Technical Field

[0001] The utility model belongs to the technical field of secondary drainage pipe fittings, in particular to a caisson secondary drainage embedded part which can automatically supplement a water seal. Background Art

[0002] Secondary drainage is an important structure in the drainage system of a building. In areas such as bathrooms, even if the ground waterproof layer is well done, it is difficult to completely avoid water penetration. The secondary drainage system can collect and discharge the moisture that may penetrate into the building structure, preventing water from accumulating in caissons or other low-lying areas.

[0003] In the prior art, water-stop embedded parts are mostly used to solve the problem of water leakage. The water-stop is provided with a water collection hole, which is connected to the main pipeline. The existing technical problems are: most water-stops are not provided with water seals, which will cause odor to be discharged from the main pipeline into the room, such as a one-way secondary drainage embedded sleeve with publication number CN218713814U; or a few structures with water seals, when there is no leakage for a long time, the water in the water seal will evaporate naturally, and the reverse odor will also occur, such as the embedded pipe through the floor slab for secondary drainage of modular integral bathroom caisson with publication number CN221569702U.

[0004] Therefore, in the technical field, there is an urgent need for a secondary drainage structure that can automatically replenish water for water sealing. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a caisson secondary drainage embedded part which can automatically replenish the water seal. The water seal function is realized by setting a U-shaped water seal structure, and the water seal box is replenished with water through the dripping eagle beak structure design, so that the water seal box can have sufficient water volume to prevent odor.

[0006] The utility model is realized as follows: a caisson secondary drainage embedded part capable of automatically replenishing water seal comprises a drainage pipe connecting pipe; a water seal box is arranged on the outer surface of the drainage pipe connecting pipe; an outer chamber and an inner chamber are arranged inside the water seal box; a first water hole communicating with the drainage pipe connecting pipe is arranged on the side of the inner chamber; a second water hole is arranged on the top of the outer chamber; a communicating hole is arranged at the bottom of the outer chamber and the inner chamber;

[0007] The first water through hole is located between the second water through hole and the connecting hole in the vertical direction;

[0008] Preferably, a fixing piece is provided at the bottom of the water seal box;

[0009] Preferably, a dripping beak is provided on the edge of the first water hole, and the dripping beak is biased toward one side of the inner chamber;

[0010] Preferably, a wing ring is provided on the outer side of the water seal box;

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] By setting a water seal box structure on the outside of the drainage pipe connecting pipe, the drainage channel is water-sealed while achieving secondary drainage to prevent the backflow of odorous gas;

[0013] By arranging a dripping eagle on the edge of the first water hole, the drainage from the drain pipe connection pipe can flow into the water seal box along the dripping eagle. When the water level in the water seal box is equal to the bottom of the first water hole, the accumulated water in the water seal box will flow into the drain pipe along the bottom of the first water hole. As long as there is drainage flowing into the drain pipe, the dripping eagle will continue to replenish water into the water seal box. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1 and Figure 4 As shown, the utility model provides a caisson secondary drainage embedded part capable of automatically replenishing water seal, comprising a drainage pipe connecting pipe 1; both ends of the drainage pipe connecting pipe 1 are connected to a drainage main vertical pipe 11; an annular water seal box 2 is provided on the outer surface of the drainage pipe connecting pipe 1; Figure 2 As shown, the water seal box 2 is provided with an outer chamber 3 and an inner chamber 4; the inner chamber 4 is provided with a first water hole 5 connected with the drain pipe connection pipe 1 on the side; the outer chamber 3 is provided with a second water hole 6 on the top; the outer chamber 3 and the inner chamber 4 are provided with a communicating hole 7 at the bottom; the first water hole 5 is located between the second water hole 6 and the communicating hole 7 in the vertical direction;

[0022] As a preferred embodiment, further, a fixing member 8 is provided at the bottom of the water seal box 2, and a screw hole is provided on the fixing member 8;

[0023] As a preferred embodiment, further, Figure 3 As shown, a dripping hawk 9 is provided on the edge of the first water hole 5, and the dripping hawk 9 is biased toward one side of the inner chamber 4;

[0024] Preferably, further, the outer side of the water seal box 2 is provided with an annular wing ring 10, which can make the waterproof sleeve and the floor slab more tightly combined, and prevent the gap between the pipe and the floor slab from leaking.

[0025] It should be noted that the first water through hole 5, the second water through hole 6 and the connecting hole 7 are all distributed in a ring along the axis of the drainage pipe, and there is no specific requirement for the number of holes.

[0026] The working principle of this utility model:

[0027] The embedded part is embedded in the floor slab, and is fixed to the bottom template of the floor slab by screws through the screw holes on the fixing part 8. It will not shift during the concrete pouring process, ensuring the installation position is accurate. The drainage pipe connecting pipe 1 is connected to the drainage main riser, and the accumulated water in the caisson first flows into the water seal box through the second water hole 6. When the water level in the water seal box 2 is flush with the lower edge of the first water hole 5, the accumulated water will flow into the drainage riser. At this time, the water level has reached the water seal height required by the design, and the odor in the riser cannot enter the room through the water seal box 2. And the water in the drainage riser will drip into the water seal box 2 through the dripping eagle mouth on the upper edge of the first water hole 5. In this way, as long as there is water flowing into the drainage riser, it will ensure that the water seal in the water seal box 2 always exists, which plays a role in continuously replenishing the water seal. The first water hole 5 is not only used for drainage and replenishing the water seal, but also can ensure the air circulation in the drainage main riser and the water seal box 2, so that the water flow in the water seal box 2 is not affected by air resistance. The height of the water seal box 2 can be set according to the thickness of the floor slab, so that the top surface of the pipe is flush with or slightly lower than the ground after installation. During installation, a layer of geotextile can be covered on the top of the pipe to prevent debris from clogging the second water holes 6. At the same time, the number of second water holes 6 can be increased as needed. The dripping hawk 9 needs to be set at least 30° away from the water seal box, and the inner wall of the pipe can be provided with spiral lines from the top of the drainage connection pipe to the dripping hawk 9, guiding the drainage in the drainage riser to the dripping hawk 9, ensuring efficient replenishment of the water seal in the water seal box.

[0028] The above description is only a preferred embodiment of the utility model, and does not constitute any form of limitation to the utility model. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent will not depart from the scope of the technical solution of the utility model.
