Description
Technical Field
[0001] The utility model belongs to the field of secondary drainage of caissons, and in particular relates to a secondary drainage structure of a caisson. Background Art
[0002] With the rapid development of society, residential drainage issues have gradually become the focus of residential buildings. In residential buildings, bathroom caissons are often concentrated areas of sewage and wastewater. Generally, sewage is discharged into the caisson through the floor drain on the bathroom floor, and then discharged into the pipe through the P-type water trap. However, a small amount of accumulated water will seep into the caisson through the gaps in the ground, and the small amount of accumulated water inside the caisson also needs to be discharged. The existing solution is mainly to set up a separate floor drain during the secondary drainage of the caisson, and connect it to the drainage riser after passing through the water trap. However, this structure is relatively complicated and inconvenient to maintain. When the water seal of the water trap dries up, it cannot be replenished in time. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model proposes a secondary drainage structure for a caisson, which uses a water leaker to simplify the complex structure inside the traditional caisson. The structure is simple and can also prevent the water seal from drying up, effectively drain water and prevent the generation of odor.
[0004] The technical solution of the utility model is achieved in this way:
[0005] A caisson secondary drainage structure comprises: a direct buried floor drain, a short pipe, a water leaker, and a P-type water trap, wherein the direct buried floor drain comprises a floor drain upper cover and a floor drain socket; the short pipe comprises a short pipe water inlet end and a short pipe water outlet end; the water leaker comprises a water leaker upper socket, a water leaker lower socket and a water leaker hole; the P-type water trap comprises a water trap water inlet end and a water trap water outlet end; the water leaker upper socket is connected to the short pipe water outlet end of the short pipe, and the water leaker lower socket is connected to the water trap water inlet end of the P-type water trap.
[0006] In a preferred embodiment, the interior of the caisson is from below the ground to above the upper socket of the water leaker.
[0007] In a preferred embodiment, the shape of the leakage hole of the water leaker includes: fan-shaped, dot-shaped or circular.
[0008] In a preferred embodiment, the water leaker is provided with a limiting ring protruding upward or downward.
[0009] In a preferred embodiment, a limiting groove is provided on the floor drain socket of the direct buried floor drain.
[0010] In a preferred embodiment, the short pipe water inlet end of the short pipe is connected to the floor drain socket of the direct buried floor drain.
[0011] In a preferred embodiment, it further comprises a water-conducting tee, and the water outlet end of the P-type water trap is connected to the water-conducting tee.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] The utility model arranges a short pipe, a water leaker and a P-type water trap in the caisson, receives the water flow of the short pipe through the upper socket of the water leaker, and then discharges the water out of the pipeline through the P-type water trap. The P-type water trap is used to store water to prevent the odor from flowing back. In addition, a small amount of accumulated water will inevitably seep into the caisson from the gaps in the floor, and a water leaker leakage hole is arranged on the periphery of the upper socket of the water leaker to discharge the accumulated water in the caisson.

[0023] 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 of 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.
[0024] See also Figure 1 to Figure 2 The utility model discloses a secondary drainage structure of a caisson, including a direct buried floor drain 1, a short pipe 2, a water leaker 3, a P-type water trap 4 and a water tee 5. The direct buried floor drain 1 is located on the bathroom floor, including a floor drain cover 11 and a floor drain socket 12. The short pipe 2 includes a short pipe water inlet end 21 and a short pipe water outlet end 22. The floor drain cover 11 is arranged on the bathroom floor surface. The floor drain socket 12 is arranged under the floor and connected to the short pipe water inlet end 21 of the short pipe 2. The water leaker 3 includes a water leaker upper socket 31, a water leaker lower socket 32 and a water leaker leakage hole 33. The P-type water trap 4 includes a water trap water inlet end 41 and a water trap water outlet end 42.
[0025] like Figure 2 As shown, the floor drain socket 12 of the direct buried floor drain 1 is arranged under the floor and connected to the short pipe water inlet end 21 of the short pipe 2. Wastewater flows in from the floor drain upper cover 11 of the direct buried floor drain 1, and flows into the short pipe 2 through the floor drain socket 12; the short pipe water outlet end 22 of the short pipe 2 is connected to the upper socket 31 of the water leaker 3, and wastewater flows from the short pipe 2 into the water leaker 3; the other end of the water leaker 3, the lower socket 32 of the water leaker, is connected to the water trap water inlet end 41 of the P-type water trap 4, and wastewater flows from the water leaker 3 into the P-type water trap 4; the water trap water outlet end 42 is connected to the water tee 5, and wastewater flows into the water tee 5 through the P-type water trap 4, thereby discharging most of the wastewater.
[0026] like Figure 1 As shown, the space from below the ground to above the upper socket 31 of the leaker is the interior of the caisson 6. A small amount of waste water may not pass through the short pipe 2, but flow into the interior of the caisson 6 from the gap in the floor. Failure to discharge the accumulated water in the interior of the caisson 6 in time can easily cause the caisson to stink. In order to solve the problem of water accumulation in the interior of the caisson 6, a leaker leakage hole 33 is provided on the periphery of the upper socket 31 of the leaker. Since the water outlet end 22 of the short pipe is connected to the upper socket 31 of the leaker, most of the waste water flows into the upper socket 31 of the leaker through the short pipe 2 and is discharged into the P-type water trap 4. The accumulated water in the interior of the caisson 6 can flow into the leaker 3 from the leaker leakage hole 33, and further flow into the P-type water trap 4 for discharge.
[0027] In a preferred embodiment, the shape of the leakage hole 33 of the leaker includes fan-shaped, dot-shaped or circular. The leaker 3 with the corresponding leakage hole shape can be selected according to different actual needs, taking into account factors such as structural strength, easy cleaning and prevention of foreign matter entry.
[0028] In this embodiment, the materials of each component include UPVC, HDPE and PP, and the surface of each component is provided with an anti-corrosion coating layer.
[0029] In this embodiment, the water leaker 3 is provided with a stop ring 34 protruding upward or downward for fixing the connection with the short pipe 2. Specifically, the stop ring 34 is arranged on the outer side of the socket 31 on the water leaker, so that the water leaker 3 is fixedly engaged with the water outlet end 22 of the short pipe.
[0030] In this embodiment, the floor drain socket 12 of the direct-buried floor drain 1 is provided with a limiting groove 13, which is used to fix the floor drain socket 12 and the short pipe water inlet end 21 during installation, and the connection is tight, and will not shift or loosen due to construction errors or later vibrations, thereby ensuring the stability and sealing of the drainage system.
[0031] The working process of this embodiment is as follows:
[0032] When there is sewage and wastewater on the ground, the sewage and wastewater first flows into the direct buried floor drain 1 from the floor, and the wastewater flows into the short pipe 2 from the direct buried floor drain 1, flows into the water leaker 3 along the short pipe 2, and then flows into the P-type water trap 4. The water originally in the P-type water trap 4 and part of the wastewater are discharged from the caisson into the pipeline along the interface of the downstream tee 5, and the remaining part of the wastewater remains in the P-type water trap 4. This process is a primary drainage; although most of the wastewater on the ground will flow into the short pipe 2 from the direct buried floor drain 1, a small amount of accumulated water will still seep into the inside of the caisson 6 through the gaps in the ground. If it is not discharged in time, it may seep and leak over time and affect the lower users and cause disputes. Therefore, it can be discharged into the P-type water trap 4 through the leakage hole 33 of the water leaker and then discharged. This process is a secondary drainage, which solves the problem of water accumulation inside the caisson 6. At the same time, because of the obstruction of the P-type water trap 4, the odor will not return to the inside of the caisson 6 and will not enter the room.
[0033] In the traditional secondary drainage structure of a caisson, the water leaker 3 in the interior 6 of the caisson was originally set as a water-stopping joint, which did not have the function of connecting the pipes of the upper and lower layers and discharging the accumulated water in the caisson at the same time. In order to discharge the accumulated water in the interior 6 of the caisson, it is necessary to set an additional direct-buried floor drain 1 in the lower layer of the caisson. In order to connect the pipes of the upper and lower layers, the upper end of the water-stopping joint is connected to a short pipe 2 to receive the sewage and waste water flowing in from the ground. The lower end of the water-stopping joint is connected to a 90° elbow, and then matched with a water-shunting tee 5. The water-shunting tee 5 has three ports. The first end of the water inlet is connected to the 90° elbow, the second end of the water inlet is connected to the direct-buried floor drain 1 inside the caisson, and the water outlet port is connected to the P-type water trap 4 to discharge the sewage and waste water into the P-type water trap through the water-shunting tee 5 and then into the pipe.
[0034] Compared with the traditional structure, the utility model simplifies the structure of the interior 6 of the caisson, and achieves the same drainage effect, preventing the water seal from drying up and effectively preventing the generation of odor.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
