Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a toilet leakage water recovery device and a construction method thereof. Background Art

[0002] Bathrooms in residential buildings are designed to be waterproof, yet water leaks are common. This not only contaminates interior finishes and erodes the building structure, but also directly impacts the lives of residents below. Analysis reveals that, in addition to design, material, and construction flaws, water accumulation caused by the caisson design of the bathroom's drop-down floor is a significant contributing factor.

[0003] Existing repair techniques for bathroom leaks include: ① excavation and re-waterproofing, along with the addition of so-called "secondary drainage systems"; ② various brick-free grouting techniques; and ③ temporary measures such as passive drainage downstairs. While effective, these measures all suffer from high costs, temporary fixes, short lifespans, and the inability to actively drain water.

[0004] The Chinese publication number is: CN219931139U, which discloses a bathroom water leakage lower layer treatment and repair component, including a floor structure plate, a construction waste backfill layer, a secondary waterproof structure layer, a bathroom drain pipe, a drainage component and a connecting pipe component. The water inlet end of the drainage component passes through the floor structure plate and is located at the lower end of the construction waste backfill layer. The drainage end of the drainage component is connected to one side of the bathroom drain pipe through the connecting pipe component.

[0005] The above-mentioned technical solution provides a bathroom water leakage lower layer treatment and repair component, which actively converts the passive treatment of the lower layer on the back water surface into an active drainage method by placing a drainage rod into the water inlet device. However, the existing bathroom water leakage lower layer treatment and repair component has a complex structure, cumbersome construction, a long construction period, and no obvious improvement in drainage pipe leakage.

[0024] Example of toilet leakage water recovery device:

[0025] See also Figure 1 and Figure 2 , which shows the preferred structure of the toilet water leakage recovery device provided by the embodiment of the present invention. As shown in the figure, the toilet water leakage recovery device includes: an anti-leakage pipe 1 and an anti-leakage joint 2; wherein,

[0026] The bottom end of the drainage floor drain 3 of the toilet (relative to Figure 1 The auxiliary drain pipe 4 is connected to the anti-leakage pipe 1, and the anti-leakage pipe 1 is sleeved on the outer periphery of the auxiliary drain pipe 4. In addition, the anti-leakage pipe 1 is also connected to the structural base plate 5 on which the sewer pipe 6 is installed, and is used to recover the leaked water in the gap between the structural base plate 5 and the sewer pipe 6 into the anti-leakage pipe 1, and to drain the water in the auxiliary drain pipe 4.

[0027] Specifically, a water trough is provided at the junction of the dry and wet areas of the bathroom, and a drainage floor drain 3 is provided in the water trough. The drainage floor drain 3 is installed through the structural bottom plate 5.

A clearance hole 51 is provided on the structural bottom plate 5, and the drainage floor drain 3 extends from the clearance hole 51 to the bottom. Due to the arrangement of the giveway hole 51, in order to avoid water leakage at the gap between the structural bottom plate 5 and the sewer pipe 6, especially water leakage at the gap between the giveway hole 51 and the drainage floor drain 3, which affects the bathroom floor, an anti-leakage pipe 1 is installed on the lower side of the structural bottom plate 5 at the giveway hole 51, and the anti-leakage pipe 1 is also connected to the auxiliary drainage pipe 4 to recover the leaked water at the gap between the structural bottom plate 5 and the sewer pipe 6 into the anti-leakage pipe, and drain the water in the auxiliary drainage pipe 4, so that the leaked water at the gap between the structural bottom plate 5 and the sewer pipe 6 and the water in the auxiliary drainage pipe 4 are all discharged into the anti-leakage pipe 1, and then discharged into the sewer pipe 6 through the anti-leakage joint 2. Among them, the anti-leakage pipe 1 is a receiving plate structure, which is received below the makeshift hole 51, and receives the leaked water and the water discharged by the auxiliary drainage pipe 4; the anti-leakage pipe 1 can be adapted to the makeshift hole 51 and the drainage floor drain 3. For example, when the drainage floor drain 3 is a circular structure, the anti-leakage pipe 1 is an adapted circular structure, which wraps the makeshift hole 51 inside.

[0028] The water inlet of the anti-leakage joint 2 (such as Figure 1 The top shown in FIG) is sleeved on the outer periphery of the anti-leakage pipe 1, and the water outlet (as shown Figure 1 The bottom end shown in the figure is sleeved on the outer periphery of the sewer pipe 6 to realize the connection between the anti-leakage pipe 1 and the sewer pipe 6, and to allow the accumulated water in the anti-leakage pipe 1 to flow back into the sewer pipe 6.

[0029] Specifically, the water inlet of the anti-leakage joint 2 (such as Figure 1 The top shown in FIG) is sleeved on the outer periphery of the anti-leakage pipe 1 and is connected to the anti-leakage pipe 1. The water outlet (as shown in FIG) Figure 1 The bottom end shown in the figure is sleeved on the outer periphery of the sewer pipe 6 and is connected to the sewer pipe 6 to realize the connection between the anti-leakage pipe 1 and the sewer pipe 6, and to allow the accumulated water in the anti-leakage pipe 1 to flow back into the sewer pipe 6.

[0030] Continue to see Figures 1 to 2 The anti-leakage pipe 1 includes: a fixed section 11 and a drainage section 12; wherein the fixed end of the fixed section 11 (such as Figure 1As shown) is connected to the structural base plate 5, and is used to recover the leaked water in the gap between the structural base plate 5 and the sewer pipe 6; the drainage section 12 is connected to the fixed section 11, and the drainage section 12 is provided with a leakage hole 121 and a drainage hole 122, the auxiliary drainage pipe 4 is inserted into the drainage hole 122, and the water in the auxiliary drainage pipe 4 is discharged, and the leakage hole 121 is used to discharge the leaked water recovered in the fixed section 11.

[0031] Specifically, the fixed section 11 can be a circular tubular structure, and the drainage section 12 can be a circular thick plate structure, and the two can be arranged eccentrically. The drainage section 12 is provided with a leakage hole 121 and a drainage hole 122. The leakage hole 121 can be one or more, which can be arranged at intervals along the circumference of the drainage hole 122 to discharge the leaked water recovered by the fixed section 11. The bottom end of the auxiliary drainage pipe 4 is inserted into the drainage hole 122, and the inner wall of the drainage hole 122 is adapted to the outer wall of the auxiliary drainage pipe 4 to achieve sheathing and communication. The fixed section 11 and the drainage section 12 can be connected by a transverse support plate 13 arranged along the cross section of the fixed section 11. The transverse support plate 13 can be a drainage plate with a slope, and can also drain the leaked water recovered by the fixed section 11 to drain it into the drainage section 12, so that the leaked water is discharged from the leakage hole 121.

[0032] In this embodiment, the top of the fixed section 11 is fixedly mounted on the clearance hole 51 of the structural base plate 5. In order to improve the connection stability between the fixed section 11 and the structural base plate 5, preferably, the fixed section 11 is facing away from the end of the drainage section 12 (such as Figure 1 A connecting plate 14 extends from the outer edge of the mounting section (shown as the top end) for connection to the structural base plate 5. Connecting plate 14 is arranged perpendicular to the fixing section 11, pressing against the bottom wall of the structural base plate 5 to enhance the connection stability. A rubber gasket 7 is positioned between connecting plate 14 and the structural base plate 5 to further prevent water leakage.

Specifically, the anti-leakage pipe connecting section 21 and the drainage pipe connecting section 22 can both be tubular structures, and the anti-leakage pipe connecting section 21 is sleeved on the outer periphery of the drainage section 12. The two are in close contact and connected to avoid falling off. Of course, the two can also be fixedly connected, which is not limited in this embodiment.

The inner diameter of the water diversion hole 231 can be smaller than the outer diameter of the sewer pipe 6 to limit the position of the sewer pipe 6.

[0035] In summary, the bathroom water leakage recovery device provided in this embodiment connects the leaked accumulated water at the structural bottom plate and the floor drain position into the anti-leakage pipe 1, and recovers the leaked accumulated water for a second time. The accumulated water in the anti-leakage pipe 1 is returned to the sewer pipe 6 through the anti-leakage joint 2.
