Description

Technical Field

[0001] This utility model relates to the field of waterproofing, specifically an auxiliary drainage device below a waterproof layer. Background Technology

[0002] A waterproof layer is installed above the floor slab to protect it from water seepage. However, if the waterproofing is not done properly or is damaged, water can accumulate between the floor slab and the waterproof layer and eventually seep into the floor slab. This makes it difficult to drain the water in time, resulting in a relatively simple method of waterproofing the floor slab and a lack of effective remedial measures after water seepage, thus affecting the comprehensiveness of the waterproofing protection for the floor slab. Utility Model Content

[0003] The purpose of this utility model is to provide an auxiliary drainage device under the waterproof layer, which can solve the problem of water seepage in the waterproof layer that cannot be drained, resulting in a large amount of water seepage in the floor slab. It can drain the water seepage that accumulates between the waterproof layer and the floor slab in a timely manner, reduce the scope and damage of the seepage, and greatly reduce the losses caused by the seepage.

[0004] To achieve the above objectives, this utility model employs the following technical solution: An auxiliary drainage device under a waterproof layer includes multiple auxiliary pipes connected to a drain pipe and multiple drainage pipes disposed between the waterproof layer and the floor slab. The top ends of the drainage pipes are connected to the auxiliary pipes, and the bottom ends of the drain pipes are connected to the auxiliary pipes. A leveling layer is provided between the waterproof layer and the floor slab. The contact position between the drainage pipes and the leveling layer is inclined. Multiple water inlet holes are provided on the side wall of the drainage pipes. Multiple drainage holes are provided between the bottom ends of the auxiliary pipes and the drain pipes. A retaining ring is provided inside the auxiliary pipes near the bottom end, and a float ball is provided below the retaining ring for use with the retaining ring.

[0005] Furthermore, the top end of the auxiliary pipe is provided with an annular pipe, the bottom end of the annular pipe is connected to the top ends of multiple auxiliary pipes, and the side of the annular pipe is connected to multiple drainage pipes.

[0006] Furthermore, the auxiliary pipe is located outside the drain pipe.

[0007] Furthermore, the drain hole is located on the side wall of the drain pipe, the bottom of the auxiliary pipe is inclined, and the bottom end of the auxiliary pipe is connected to multiple drain holes on the side wall of the drain pipe.

[0008] Furthermore, the auxiliary pipe is located inside the drain pipe.

[0009] Furthermore, the drainage pipe penetrates the side wall of the drainage pipe and is connected to the side of the auxiliary pipe near the top.

[0010] Furthermore, a vertical reinforcing layer is provided at the end of the waterproof layer that contacts the drain pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The structure of this utility model sets multiple drainage pipes between the waterproof layer and the floor slab layer, and sets multiple connected auxiliary pipes on the drainage pipe. The top ends of the drainage pipes and the auxiliary pipes are connected, and the bottom ends of the drainage pipes and the auxiliary pipes are connected. A leveling layer is set between the waterproof layer and the floor slab layer. The contact position between the drainage pipes and the leveling layer is inclined. Multiple water inlet holes are set on the side wall of the drainage pipes. When the waterproof layer is improperly constructed or damaged, causing water seepage, the seepage will be temporarily absorbed by the leveling layer. Then, the seepage will gradually enter the drainage pipes in contact with the leveling layer through the water inlet holes, and then enter the drainage pipes through the auxiliary pipes. This realizes the timely discharge of water seepage between the waterproof layer and the floor slab layer, greatly reducing the scope and damage of water seepage and reducing the losses caused by water seepage. 2. Multiple drainage holes are provided between the auxiliary pipe and the bottom end of the drain pipe. A retaining ring is located near the bottom of the auxiliary pipe, and a float ball is located below the retaining ring to cooperate with the retaining ring. With this structure, when the drain pipe is draining, the water in the drain pipe enters the auxiliary pipe through the bottom end of the auxiliary pipe, causing the float ball at the bottom end of the auxiliary pipe to float up. This float ball then contacts the retaining ring above and seals the auxiliary pipe, preventing water from flowing back into the auxiliary pipe and the drain pipe during the drainage process. This ensures the waterproof seal between the waterproof layer and the floor slab layer. When seepage water enters the auxiliary pipe from the drain pipe, the float ball separates downward from the retaining ring under the impact of the water flow and the action of gravity, opening the auxiliary pipe and realizing the automatic drainage of seepage water. While ensuring the smooth drainage of seepage water, this reduces the occurrence of backflow and further improves the waterproof effect. Attached Figure Description

[0017] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0018] Reference Figure 1This utility model describes an auxiliary drainage device below a waterproof layer. The main structure includes multiple auxiliary pipes 2 connected to a drain pipe 1 and multiple drainage pipes 5 positioned between a waterproof layer 3 and a floor slab layer 4. A bonding layer and a surface layer are sequentially arranged above the waterproof layer 3, and the floor slab layer 4 lies below the waterproof layer 3. Multiple drainage pipes 5 are arranged horizontally between the waterproof layer 3 and the floor slab layer 4, surrounding the drain pipe 1. The auxiliary pipes 2 are arranged vertically to connect the drainage pipes 5 and the drain pipe 1. The top of each drainage pipe 5 is connected to the top of the auxiliary pipe 2, and the bottom of each drain pipe 1 is connected to the bottom of the auxiliary pipe 2. This structure allows water to enter through the drainage pipes 5... Under the influence of gravity, the seepage water can automatically flow along the auxiliary pipe 2 to the drain pipe 1, improving the smoothness of water drainage. A leveling layer 6 is provided between the waterproof layer 3 and the floor slab layer 4. The leveling layer 6 is used to fill the space between the waterproof layer 3 and the floor slab layer 4, so that the waterproof layer 3 is inclined towards the drain pipe 1, ensuring the smoothness of drainage in the house. The contact position between the drain pipe 5 and the leveling layer 6 is inclined. This structure can increase the contact area between the end of the drain pipe 5 and the leveling layer 6, so that the seepage water can enter the drain pipe 5 more quickly after entering the leveling layer 6, improving the efficiency of water drainage. The side wall of the drain pipe 5 has multiple through-holes. The inlet hole 7 allows seepage water accumulating in the leveling layer 6 surrounding the drainage pipe 5 to gradually enter the drainage pipe 5 through the inlet hole 7, making the drainage more thorough and rapid. Multiple drainage holes 8 are provided between the bottom end of the auxiliary pipe 2 and the drainage pipe 1. This structure allows seepage water inside the auxiliary pipe 2 to pass through the multiple drainage holes 8 before entering the drainage pipe 1. A retaining ring 9 is fixed inside the auxiliary pipe 2 near its bottom end by welding or integral molding. A float ball 10 is provided below the retaining ring 9 to cooperate with it. When the drainage pipe 1 is draining normally, when the water level in the drainage pipe 1 is high, water flows through the drainage holes 8. When the water enters the auxiliary pipe 2, the float ball 10 floats up under the buoyancy of the water and contacts the baffle ring 9 above, sealing the baffle ring 9 and thus closing the auxiliary pipe 2. This prevents water from flowing back into the auxiliary pipe 2 and the drainage pipe 5 during normal drainage, ensuring the seal between the waterproof layer 3 and the floor slab layer 4 and preventing backflow during drainage. When the seepage water in the drainage pipe 5 is discharged through the auxiliary pipe 2, the float ball 10 remains below the baffle ring 9 and separates from the baffle ring 9 under the impact of gravity and water flow. The float ball 10 is located at the bottom of the auxiliary pipe 2 and does not block all the drainage holes 8, ensuring the smooth discharge of seepage water and further improving the waterproofing effect on the floor slab layer 4.

[0019] Preferred, refer to Figure 2The top end of the auxiliary pipe 2 is fixed with an annular pipe 11 by welding or integral molding. The bottom end of the annular pipe 11 is connected to the top ends of multiple auxiliary pipes 2. The side of the annular pipe 11 is connected to multiple drainage pipes 5. This structure allows the annular pipe 11 to connect drainage pipes 5 and auxiliary pipes 2 at multiple locations at the same time, so that the auxiliary pipes 2 at multiple locations can drain water together, further improving the effect of draining seepage water from different locations.

[0020] Preferred, refer to Figure 3 The auxiliary pipe 2 is located outside the drain pipe 1. With this structure, when the diameter of the drain pipe 1 is relatively small, the auxiliary pipe 2 can be set outside the drain pipe 1, thereby reducing the space occupied inside the drain pipe 1 and not affecting the drainage efficiency of the drain pipe 1 with a small diameter.

[0021] Preferably, the drain hole 8 is disposed on the side wall of the drain pipe 1, the drain pipe 1 penetrates the side wall of the drain pipe 1, and the bottom of the auxiliary pipe 2 is inclined toward the drain pipe 1, so that the seepage water in the auxiliary pipe 2 can be uniformly collected in the direction of the drain pipe 1. The bottom end of the auxiliary pipe 2 is connected to multiple drain holes 8 on the side wall of the drain pipe 1, and the bottom end of the auxiliary pipe 2 covers multiple drain holes 8 on the side wall of the drain pipe 1. This structure can ensure the connection effect between the auxiliary pipe 2 and the drain pipe 1 without affecting the normal drainage efficiency of the drain pipe 1.

[0022] Preferred, refer to Figure 4 The auxiliary pipe 2 is located inside the drain pipe 1. When the diameter of the drain pipe 1 is large, the auxiliary pipe 2 is set inside the drain pipe 1. This structure can save the construction steps outside the drain pipe 1, reduce the difficulty of construction, and improve the efficiency of construction.

[0023] Preferably, the drainage pipe 5 is connected to the side of the auxiliary pipe 2 near the top after penetrating the side wall of the drain pipe 1. This structure allows the drainage pipe 5 to extend into the interior of the drain pipe 1 and connect with the side of the auxiliary pipe 2 after penetrating the side wall of the drain pipe 1, making the overall structure more compact and the overall sealing better.

[0024] Preferably, the end of the waterproof layer 3 that contacts the drain pipe 1 is provided with a vertical reinforcing layer 12. This structure allows the waterproof layer 3 to effectively cover the connection between the floor slab layer 4 and the drain pipe 1, so that when the room is drained, the water flow will not seep through the gap between the drain pipe 1 and the floor slab layer 4, further improving the waterproof sealing effect of the floor slab layer 4.

[0025] Working Principle: This utility model features a structure with multiple drainage pipes 5 between the waterproof layer 3 and the floor slab 4. Multiple auxiliary pipes 2 are connected to the drain pipe 1. The top ends of the drainage pipes 5 and auxiliary pipes 2 are connected, and the bottom ends of the drain pipe 1 and auxiliary pipes 2 are connected. A leveling layer 6 is provided between the waterproof layer 3 and the floor slab 4. The contact points between the drainage pipes 5 and the leveling layer 6 are inclined. Multiple water inlet holes 7 are provided on the sidewalls of the drainage pipes 5. With this structure, when the waterproof layer 3 is improperly constructed or damaged, causing water seepage, the seepage is temporarily absorbed by the leveling layer 6. Then, the seepage gradually enters the drainage pipes 5 in contact with the leveling layer 6 through the water inlet holes 7, and then enters the drain pipe 1 through the auxiliary pipes 2. This achieves timely drainage of the seepage between the waterproof layer 3 and the floor slab 4, greatly reducing the scope and damage of the seepage and minimizing losses caused by seepage. The auxiliary pipes 2... Multiple drainage holes 8 are provided between the bottom end and the drain pipe 1. A retaining ring 9 is provided inside the auxiliary pipe 2 near the bottom end. Below the retaining ring 9, there is a float ball 10 that works in conjunction with the retaining ring 9. With this structure, when the drain pipe 1 is draining, the water in the drain pipe 1 enters the auxiliary pipe 2 through the bottom end of the auxiliary pipe 2, causing the float ball 10 at the bottom end of the auxiliary pipe 2 to float up. This float ball then contacts the retaining ring 9 above and seals the auxiliary pipe 2, preventing water from flowing back into the auxiliary pipe 2 and the drainage pipe 5 during the drainage process of the drain pipe 1. This ensures the waterproof sealing between the waterproof layer 3 and the floor slab layer 4. When seepage water enters the auxiliary pipe 2 from the drainage pipe 5, the float ball 10 separates downward from the retaining ring 9 under the impact of the water flow and the action of gravity, opening the auxiliary pipe 2 and realizing the automatic discharge of seepage water. This reduces the occurrence of backflow while ensuring the smooth discharge of seepage water, further improving the waterproof effect.
