Description

Technical Field

[0001] This utility model relates to the field of outdoor floor tile drainage technology, and in particular to a drainage device. Background Technology

[0002] Some of the ideas and refinements regarding rapid rainwater drainage and collection systems have already resulted in products or patents. Among them, the Chinese utility model patent CN219992080U, entitled "A Sponge City Road Surface Pavement Structure with Impact Resistance," discloses a method of setting water guide holes in permeable bricks, setting a first water collection pipe on the leveling layer, laying a second water collection pipe and an external water storage module on the base layer. Rainwater passes through the water guide holes, the first water collection pipe, and the second water collection pipe in sequence, and finally collects in the water storage module. This technical solution has the following shortcomings: 1. Permeable bricks are permeable, and most rainwater falling on them seeps directly into the ground, with only a small portion being collected; 2. Permeable bricks require prefabrication, limiting their applicability; 3. The water guide holes on the permeable bricks and the inlet holes on the first water collection pipe must be matched, making construction difficult, resulting in dense water collection pipes, numerous bends, complex drainage paths, turbulent water flow within the pipes, and uncertain drainage performance, while also increasing costs; 4. The laying of plaza bricks and permeable bricks typically involves only one layer of dry-mixed cement mortar, 3-5cm thick, from the surface of the base layer to the bottom of the brick, used for leveling the base and guiding drainage. The principle is that the dry-mixed cement mortar slowly absorbs moisture from the air and hardens, forming a relatively loose and porous base layer. Its thickness makes it impossible to arrange a first layer of water collection pipes on the leveling layer and a second layer on the base layer, as described in the aforementioned patent. 5. The water storage modules require matching pump sets. If they are densely packed, the volume of the water storage modules is too small, making them unusable compared to the cost and maintenance of the pump sets. Conversely, if large water storage modules are used, the second collection pipe path becomes too long, construction is complex, and costs are high. Therefore, utilizing the main drainage network on-site is more reasonable for rainwater recycling. 6. The paving of plaza bricks and permeable bricks involves laying them one by one on the leveling layer, resulting in a cluttered site with materials, personnel, and equipment. If the first and second collection pipes are laid all at once, they may be damaged during construction. If laid alongside the paving bricks, personnel work in a mixed and difficult manner. In conclusion, the drainage effect of this patented technical solution is uncertain, the project is complex, the cost is high, and its applicability is limited. Utility Model Content

[0003] This utility model provides a drainage device, the purpose of which is to improve the drainage effect of the drainage device and reduce the construction difficulty and production cost of the drainage device.

[0004] To achieve the above objectives, this utility model provides a drainage device comprising multiple drainage units. Each drainage unit is laid within a sand and lime layer beneath floor tiles. Each drainage unit has a water collection hole on the side of the floor tile facing vertically. Each drainage unit includes a first drainage pipe and a second drainage pipe that are interconnected. The first and second drainage pipes are arranged intersectingly. The first end of the first drainage pipe along the axial direction is a first interface, and the second end of the first drainage pipe along the axial direction is a second interface. In two adjacent first drainage pipes, the first interface of one first drainage pipe can communicate with the second interface of the other first drainage pipe to connect the two adjacent drainage units. The first drainage pipe can also communicate with a main drainage pipe connected to the outside, allowing the water collected in the drainage device to be discharged to the outside.

[0005] In one embodiment, the first drain pipe extends along the slope of the floor tiles, and the angle between the second drain pipe and the first drain pipe is in the range of 120° to 150°.

[0006] In one embodiment, there are multiple second drain pipes, and the multiple second drain pipes are arranged symmetrically about the axis of symmetry of the first drain pipe.

[0007] In one embodiment, the diameter of the first drain pipe is greater than or equal to the diameter of the second drain pipe.

[0008] In one embodiment, the number of drainage devices is multiple, and the multiple drainage devices are arranged at intervals along a direction that intersects the slope direction of the floor tiles.

[0009] The above-mentioned solution of this utility model has the following beneficial effects:

[0010] In this embodiment, the first and second drain pipes are arranged in a cross pattern, expanding the coverage area of ​​the drainage unit in the direction intersecting the axial direction of the first drain pipe. Both the first and second drain pipes have water collection holes on the side closest to the floor tile in the vertical direction, improving the water collection capacity of the drainage unit and thus reducing the possibility of water accumulation under the floor tile. Adjacent drainage units can be connected through the first and second interfaces of adjacent first drain pipes, for example, by plugging them together. This is convenient and relatively easy to construct, eliminating the need for specialized installers. The floor tile installers can simply install the drainage units one by one in the sand and lime layer as the floor tiles are laid, making it simple and reliable. Since the drainage unit is located within the sand and lime layer, the operating environment is relatively enclosed and less affected by the external environment. Therefore, the quality requirements for the drainage unit's materials are not high, allowing for an adaptive reduction in the quality of the materials used, which helps improve the cost-effectiveness of the drainage device.

[0011] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0020] Please see Figure 1 The drainage device 100 includes multiple drainage units 1, which are laid within a sand and lime layer beneath the paving stones. The sand and lime layer, acting as a subbase in direct contact with the paving stones, is typically used for leveling the stones and creating a slope that facilitates drainage. The sand and lime layer is usually made of dry-mix cement mortar, which slowly absorbs moisture from the air and hardens, forming a loose, porous, and relatively strong material. The thickness of the sand and lime layer is typically 3cm to 5cm. The paving stones are bricks used for outdoor ground surfaces, such as those used in plazas. Please refer to [link to relevant documentation]. Figure 3 The drainage unit 1 has a water collection hole 1a on the side of the floor tile facing vertically. The water collection hole 1a is used to collect water, such as rainwater, that seeps from the floor tile into the sand and lime layer, thus forming a water flow within the drainage unit 1. The drainage unit 1 does not have a water collection hole 1a on the side facing away from the floor tile in the vertical direction, so that the water flowing into the drainage unit 1 can be collected into a water flow within the drainage unit 1, facilitating the discharge of water that has seeped into the sand and lime layer to the outside through the drainage unit 1.

[0021] Please see Figure 1 and Figure 2 The drainage unit 1 includes a first drainage pipe 11 and a second drainage pipe 12 that are interconnected. It should be noted that both the first drainage pipe 11 and the second drainage pipe 12 are laid along their own axial direction within the sand and lime layer. The materials of the first drainage pipe 11 and the second drainage pipe 12 are not limited. Since the drainage device 100 of this application is laid within the sand and lime layer, the operating environment of the drainage device 100 is relatively enclosed and less affected by the external environment. Therefore, the quality requirements for the materials of the first drainage pipe 11 and the second drainage pipe 12 are not high. Thus, the materials of the first drainage pipe 11 and the second drainage pipe 12 can both be plastic or recycled plastic. The interconnected first drainage pipe 11 and the second drainage pipe 12 can be constructed as a single thermoplastic molding, resulting in lower production costs for the drainage unit 1. Please refer to... Figure 1 and Figure 2 The first drain pipe 11 and the second drain pipe 12 are arranged in a cross manner, which expands the coverage of the drainage unit 1 in the direction of axial intersection with the first drain pipe 11. Furthermore, the first drain pipe 11 and the second drain pipe 12 are both provided with water collection holes 1a on the side of the floor tile in the vertical direction, which improves the water collection capacity of the drainage unit 1.

[0022] Please see Figure 2 The first end of the first drain pipe 11 along the axial direction is the first interface 11a, and the second end of the first drain pipe 11 along the axial direction is the second interface 11b. In two adjacent first drain pipes 11 along the axial direction, the first interface 11a of one first drain pipe 11 can communicate with the second interface 11b of the other first drain pipe 11 to connect the two adjacent drainage units 1. For example, the direction of the second interface 11b toward the first interface 11a is the flow direction of water in the first drain pipe 11. The first interface 11a can be a spigot, and the second interface 11b can be a socket, that is, the diameter of the second interface 11b is slightly larger than the diameter of the first interface 11a, so that the first interface 11a of one first drain pipe 11 can be inserted into the second interface 11b of another first drain pipe 11, thereby allowing the water in one first drain pipe 11 to flow directly into the other first drain pipe 11 through the first interface 11a, reducing the possibility of water leakage at the spigot position of the first interface 11a and the second interface 11b. Furthermore, the first interface 11a and the second interface 11b of the first drain pipe 11 eliminate the need for additional joints, elbows and other components during the splicing of the drainage unit 1, which facilitates installation and reduces costs.

[0023] Please see Figure 1 The first drain pipe 11 can be connected to the main drain pipe 200, which connects to the outside, so that the water collected in the drainage device 100 can be discharged to the outside. The main drain pipe 200 can be a municipal pipe network, a culvert connected to the municipal pipe network, or a connecting opening of a curb. For example, to facilitate drainage, the curb is usually the lowest point of the ground connected to the curb. The first interface 11a of the outermost first drain pipe 11 can be inserted into the connecting opening of the curb, so that the water collected in the drainage device 100 can be discharged to the outside through the connecting opening of the curb and then flow into the municipal pipe network.

[0024] In this embodiment, the first drain pipe 11 and the second drain pipe 12 are arranged in a cross pattern, expanding the coverage area of ​​the drainage unit 1 in the direction of axial intersection with the first drain pipe 11. Both the first drain pipe 11 and the second drain pipe 12 have water collection holes 1a on the side of the floor tile in the vertical direction, improving the water collection capacity of the drainage unit 1 and thus reducing the possibility of water accumulation under the floor tile. Two adjacent drainage units 1 can be connected through the first interface 11a and the second interface 11b of the two adjacent first drain pipes 11, for example, by plugging them together. This is convenient and relatively easy to construct, eliminating the need for specialized installers. Floor tile installers can simply install the drainage units 1 one by one in the sand and lime layer as the floor tiles are laid, making it simple and reliable. Since the drainage unit 1 is located within the sand and lime layer, the operating environment is relatively enclosed and less affected by the external environment. Therefore, the quality requirements for the material of the drainage unit 1 are not high, and the quality of the material used in the drainage unit 1 can be adaptively reduced, which helps improve the cost-effectiveness of the drainage device 100 of this application.

[0025] In one embodiment, please refer to Figure 2 The first drain pipe 11 extends along the slope of the floor tiles, allowing it to not only collect water to form a flow within it, but also to discharge the water into the environment under gravity. The angle between the second drain pipe 12 and the first drain pipe 11 ranges from 120° to 150°. For example, Figure 2 The angle shown by S1 is the angle between the second drain pipe 12 and the first drain pipe 11, where 120°≤S1≤150°. Since the first drain pipe 11 is arranged along the slope of the floor tiles, the second drain pipe 12 forms a large angle with the first drain pipe 11. This results in the end of the second drain pipe 12 that is away from the first drain pipe 11 along its own axis being higher than the other end of the second drain pipe 12 along its own axis. Consequently, the water collected in the second drain pipe 12 can flow into the first drain pipe 11 under the action of gravity, so that the drainage unit 1 has a better drainage capacity over a larger area.

[0026] For example, the angle between the second drain pipe 12 and the first drain pipe 11 can be 120°, 130°, 140° or 150°.

[0027] In one embodiment, please refer to Figure 1 and Figure 2 There are multiple second drain pipes 12, which are arranged symmetrically about the axis of the first drain pipe 11 to further increase the coverage area of ​​the drainage unit 1 and improve its drainage capacity. For example, please refer to... Figure 2The drainage unit 1 includes a first drainage pipe 11 and two second drainage pipes 12. The two second drainage pipes 12 are symmetrically arranged on both sides of the first drainage pipe 11 with the axial direction of the first drainage pipe 11 as the axis of symmetry. Multiple drainage units 1 are connected along the axial direction of the first drainage pipe 11 to form a drainage system as shown in the figure. Figure 1 The fishbone-shaped drainage device 100 is shown.

[0028] In one embodiment, the diameter of the first drain pipe 11 is greater than or equal to the diameter of the second drain pipe 12. The water collected in the second drain pipe 12 can flow into the first drain pipe 11. In addition, the first drain pipe 11 can also collect water through the water collection hole 1a. The diameter of the first drain pipe 11 is greater than or equal to the diameter of the second drain pipe 12 to improve the capacity of the first drain pipe 11 to accommodate larger water flows, reduce the possibility of water collected in the first drain pipe 11 overflowing from the water collection hole 1a of the first drain pipe 11, and improve the drainage capacity of the drainage device 100.

[0029] For example, the diameter of both the first drain pipe 11 and the second drain pipe 12 can be in the range of 20mm to 50mm. The length of both the first drain pipe 11 and the second drain pipe 12 can be in the range of 30cm to 50cm.

[0030] In one embodiment, there are multiple drainage devices 100, which are arranged at intervals along a direction intersecting the slope direction of the floor tiles, thereby expanding the coverage area of ​​the drainage devices 100. The multiple drainage devices 100 arranged at intervals can drain water together, thereby improving the drainage efficiency of the floor where the drainage devices 100 of this application are installed.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
