A two-row system for preventing water seepage in a bathroom drain tile joint

Abstract

A secondary drainage system for draining water seeping from tile grout in bathrooms addresses the technical problem mentioned in the background art: secondary drainage relies on secondary leveling, requiring a drainage slope of at least 2° with the ground as the base layer and the secondary drain outlet as the lowest point. Therefore, without leveling the ground, water seeping into the tile grout cannot be effectively drained. The system includes a main drain pipe with an inlet and an outlet at both ends. Four branch pipes are connected to the main drain pipe, each connected to the side wall of the main drain pipe and evenly distributed circumferentially. Each branch pipe has a connecting pipe with several through holes for collecting water from the grout between adjacent tiles and discharging it into the branch pipe. Adjacent connecting pipes have connecting components, including a first connector, a second connector, a first elbow, a second elbow, and a plug.

Description

Technical Field

[0001] This utility model relates to the field of secondary drainage technology, specifically to a secondary drainage system for draining water seeping from tile grout in bathrooms. Background Technology

[0002] Secondary drainage is a drainage system installed above the waterproof layer and below the floor tiles to drain water that has seeped into the base layer. Before secondary drainage is installed, the surface is leveled and a slope is made with the secondary drainage outlet as the lowest point so that the water can flow smoothly to the drainage outlet.

[0003] Existing secondary drainage technology relies on secondary leveling, which requires the ground as the base layer and the secondary drainage outlet as the lowest point, creating a drainage slope of no less than 2°. Therefore, without leveling the ground, water overflowing into the tile gaps cannot be effectively drained. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a secondary drainage system for draining water seeping from tile grout in bathrooms. This system solves the technical problem mentioned in the background art, where secondary drainage relies on secondary leveling, requiring the ground as the base layer and the secondary drain outlet as the lowest point, creating a drainage slope of no less than 2°. Therefore, without leveling the ground, the water seeping into the tile grout cannot be effectively drained.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: It includes a main drain pipe, with an inlet and an outlet at each end. Four branch pipes are connected to the main drain pipe, each branch pipe being connected to the side wall of the main drain pipe and evenly distributed circumferentially. Each branch pipe has a connecting pipe with several through holes. The connecting pipe is used to collect water from the gaps between two adjacent tiles and discharge it to the branch pipe. Adjacent connecting pipes have connecting assemblies, including a first connector, a second connector, a first elbow, a second elbow, and a plug.

[0006] Working principle:

[0007] Water seeping into the gaps between bathroom floor tiles enters the connecting pipe through several through-holes. The connecting pipe is directly positioned below the tile gaps. The collected water is transported horizontally through the connecting pipe to the connected branch pipe. The branch pipe has a flat structure and is evenly distributed around the circumference of the main drain pipe, ensuring that water can flow in from multiple directions. The water in the branch pipe further flows into the main drain pipe. The main drain pipe forms a directional flow path through the inlet and outlet, ultimately discharging the water from the outlet out of the system. Adjacent connecting pipes are flexibly connected through components such as the first connector, second connector, first elbow, second elbow, and plugs to adapt to different tile gap layouts, ensuring that the collection area covers the entire floor without leakage.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] First, through the active collection connection pipe design, the water is directly diverted from the tile gaps, overcoming the limitation of traditional secondary drainage that must rely on ground leveling. Even if the ground is not level or the slope is insufficient, it can still effectively drain water.

[0010] Secondly, multiple branch pipes are evenly distributed around the main drainage pipe, and combined with the multiple through holes on the connecting pipe, the water collection area is expanded, accelerating the convergence and discharge efficiency of seepage. The connecting components allow for flexible arrangement of connecting pipes to adapt to different bathroom sizes and tile grout lines, improving applicability and installation convenience.

[0011] Third, by actively diverting water, it avoids water stagnation in the base layer under the floor tiles, reducing problems such as aging of the waterproof layer, hollow tiles, or mold growth caused by water accumulation. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] like Figure 1 As shown, a two-stage drainage system for draining water seeping from tile grout in a bathroom includes a main drain pipe 1. The main drain pipe 1 has an inlet 2 and an outlet 3 at each end. Four branch pipes 4 are connected to the main drain pipe 1, each branch pipe 4 being connected to the side wall of the main drain pipe 1 and evenly distributed circumferentially. The connection points of the branch pipes 4 and the main drain pipe 1 are arranged in a cross shape. The ends of the branch pipes 4 are sealed with a semi-circular arc-shaped structure. The main drain pipe 1 serves as the core channel. Its top inlet 2 receives water flowing in from outside, such as water drained directly from a floor drain. The bottom outlet 3 discharges the collected water from the system. The four branch pipes 4 are symmetrically distributed in a cross shape and connected to the side wall of the main drain pipe 1, forming a horizontal drainage network to ensure even collection of seepage water from multiple directions. The main drain pipe 1 and branch pipes 4 are made of PVC plastic and are connected by hot-melt socket joints or adhesive bonding to ensure sealing. The semi-circular arc-shaped seals at the ends of the branch pipes 4 are injection molded in one piece to prevent leakage.

[0023] like Figure 1 and Figure 3 As shown, each branch pipe 4 is equipped with a connecting pipe 5, and the connecting pipe 5 has several through holes 6. The connecting pipe 5 is used to collect water between the gaps of two adjacent tiles and discharge it to the branch pipe 4. The through holes 6 are evenly distributed in multiple rows on the connecting pipe 5. The connecting pipe 5 is laid directly below the tile gaps. The multiple rows of evenly distributed through holes 6 on its surface facilitate the collection of water seeping into the tile gaps. The water flows into the interior of the connecting pipe 5 through the through holes 6, and then flows laterally into the branch pipe 4 connected to it. The connecting pipe 5 is made of high-density polyethylene. The through holes 6 are formed by drilling or injection molding. The connecting pipe 5 and the branch pipe 4 are connected by a socket-type sealing ring or a hot-melt socket connection, which is convenient for installation and leak-proof.

[0024] like Figure 4 and Figure 5 and Figure 6 and Figure 7As shown, two adjacent connecting pipes 5 are provided with connecting components. The connecting components include a first connector 7, a second connector 8, a first elbow 9, a second elbow 10, and a plug 11. The first connector 7, the second connector 8, the first elbow 9, the second elbow 10, and the plug 11 are used to flexibly connect adjacent connecting pipes 5 to adapt to different bathroom layouts and tile grout directions. The plug 11 seals the end of the connecting pipe 5 to prevent water from overflowing from the end and ensures that the water flows only in the direction of the branch pipe 4.

[0025] like Figure 4 As shown, the first connector 7 is a tee connector, and its structure includes: a vertically arranged first long pipe section 12, both ends of the first long pipe section 12 are semi-circular arc-shaped seals, a first lateral extension section 13 is provided on one side of the first long pipe section 12, and the end of the first lateral extension section 13 is a semi-circular arc-shaped seal, the axis of the first long pipe section 12 and the axis of the first lateral extension section 13 are perpendicular to each other. The first connector 7 is a tee connector, its first long pipe section 12 is connected to the connecting pipe 5, and the first lateral extension section 13 is connected to the connecting pipe 5, so as to realize the convergence and conversion of vertical and horizontal directions.

[0026] like Figure 5 As shown, the second connector 8 is a slanted tee head, the structure of which includes: a vertically arranged second long pipe section 14, both ends of the second long pipe section 14 are semi-circular arc-shaped seals, a second lateral extension section 15 is provided on one side of the second long pipe section 14, and the end of the first lateral extension section 13 is a semi-circular arc-shaped seal, the included angle between the second long pipe section 14 and the second lateral extension section 15 is 55° to 65°. As a slanted tee, the 55° to 65° slant design of the second connector 8 can adapt to non-right angle connection scenarios and guide the water flow to smoothly change direction.

[0027] like Figure 6 and Figure 7 As shown, the first elbow 9 has two ends of a first straight pipe section 16 and a quarter-circle transition section in the middle. The axes of the two first straight pipe sections 16 are perpendicular to each other. The opening edges of the first straight pipe sections 16 at both ends have an arc-shaped flared structure. The second elbow 10 has two ends of a second straight pipe section 17. The included angle between the two second straight pipe sections 17 is 55° to 65°. The opening edges of the second straight pipe sections 17 at both ends have an arc-shaped flared structure. The first elbow 9 achieves a vertical turn through a 90° arc transition, and the second elbow 10 achieves an oblique turn through an included angle of 55° to 65°. Both are used to adjust the direction of the connecting pipe 5 to avoid dead bends that cause poor drainage.

[0028] like Figure 2 and Figure 3As shown, the plug 11 is used to prevent water from overflowing from the end of the connecting pipe 5. The outlet 3 is provided with a barrier net 18 to block debris from entering the outlet 3 through the connecting pipe 5 and the inlet 2. The plug 11 seals the end of the connecting pipe 5 to form a closed drainage path. The barrier net 18 is installed at the outlet 3 to filter debris such as sand and hair to prevent blockage of the downstream pipe. The plug 11 is a PVC press-type sealing cap, and the barrier net 18 is a stainless steel mesh, which is fixed inside the outlet 3 by a slot or thread.

[0029] Working principle:

[0030] Water seeping into the tile grout first passes through a connecting pipe 5 with multiple rows of evenly spaced through holes 6 and is then horizontally transported to branch pipes 4 by the internal flow of the pipe. Four cross-shaped branch pipes 4 converge the water flow from different directions into the main drain pipe 1. The main drain pipe 1 receives additional water flow through the inlet 2, such as direct drainage from the floor drain, and discharges it centrally through the bottom outlet 3. The first connector 7, the second connector 8, the first elbow 9, and the second elbow 10 are flexibly adapted to the tile grout layout with different angle structures to ensure full coverage of the collection range. At the same time, the plug 11 seals the end of the pipe to prevent leakage. Finally, the barrier net 18 at the outlet 3 filters out debris, completing the entire process of anti-clogging and drainage.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
