Description

Technical Field

[0001] This utility model belongs to the field of building drainage and landscape paving technology, specifically relating to a prefabricated linear drainage ditch suitable for stone paving on fully underground garages. Background Technology

[0002] With the acceleration of urbanization and the increase in land utilization, public buildings (especially commercial complexes and office buildings) are usually equipped with fully underground parking garages to meet the growing parking demand. To meet the load-bearing requirements for vehicle passage and parking, the landscape paving layer on the top slab of the underground garage, especially the stone paving, is usually 5cm to 8cm thick, far exceeding the thickness of stone paving in conventional indoor or pedestrian areas (usually 2-3cm).

[0003] When setting up drainage systems in areas with thick stone paving, linear drainage ditches are widely used due to their simplicity, aesthetics, and high drainage efficiency. Currently, the common solution is to use stainless steel linear drainage ditch covers in conjunction with U-shaped resin concrete or plastic drainage channels. However, this combination solution has the following significant drawbacks: (1) High cost and poor compatibility: Standard stainless steel linear covers are mainly compatible with conventional stone with a thickness of 2-3cm. When applied to stone paving with a thickness of 5-8cm, specially customized thickened or reinforced stainless steel covers with added ribs at the bottom are required to ensure sufficient load-bearing strength, which leads to a sharp increase in the cost of the cover itself. (2) Limited matching and cost superposition: Customized thickened stainless steel covers can often only be used with specific U-shaped resin drainage channels, limiting the choice of more economical traditional brick or precast concrete drainage ditch foundations, further increasing the overall cost of the drainage system. (3) Inconvenient maintenance: Stainless steel covers are usually installed in sections, and the sections need to be pressed together to ensure aesthetics. Routine cleaning and maintenance mainly rely on flushing ports set at intervals (e.g., every 10 meters) for flushing, which is difficult to thoroughly clean the sediment in the trench, resulting in low efficiency, and the flushing ports themselves may also affect the overall aesthetics. (4) Complex construction: It involves the combined installation of various materials such as stone, stainless steel cover plates, and resin trenches, and the procedures are relatively complicated, increasing the on-site construction time and management difficulty.

[0004] Therefore, when existing technologies are applied to linear drainage scenarios with thick stone paving, they face problems such as high cost, complex construction, inconvenient maintenance, and limited selection of trench foundations. There is an urgent need for a more economical, efficient, aesthetically pleasing, and easy-to-maintain solution. Summary of the Invention

[0005] Purpose of the invention: The purpose of this utility model is to address the shortcomings of the existing technology by providing a prefabricated linear drainage ditch suitable for stone paving in fully underground garages. While meeting the aesthetic and functional requirements of linear drainage ditches, it reduces costs and also meets the requirements of property cleaning and ditch diversity.

[0006] Technical solution: The prefabricated linear drainage ditch of this utility model is applicable to stone paving in a fully underground garage, including a linear ditch cover plate, wherein the linear ditch cover plate is composed of a whole piece of stone, and the stone includes a top surface and a bottom surface.

[0007] A top drainage groove is formed on the top surface of the stone along its length. The top drainage groove is used to collect rainwater from the paved surface and form a linear visual effect. The top drainage groove has a preset width and depth, but does not penetrate the overall thickness of the stone.

[0008] Meanwhile, on the bottom surface of the stone, at a position corresponding to the top drainage groove, a bottom through groove is formed. The width of the bottom through groove is basically corresponding to the width of the top drainage groove. Importantly, the bottom through groove penetrates the remaining part of the stone along the thickness direction, forming a channel connecting the top drainage groove and the area under the cover plate.

[0009] Furthermore, the length of the bottom through groove is less than the length of the top drainage groove. By controlling the length of the bottom through groove, ungrooved portions are left at both ends of the bottom surface of the stone, and these ungrooved portions constitute the structural connection parts. These structural connection parts, like bridges, maintain the structural strength and rigidity of the grooved stone as a whole, ensuring that it is not easily broken when bearing loads.

[0010] Through the above structural design, the cover plate of this utility model cleverly utilizes the stone itself and achieves the function of a drainage cover plate through a specific grooving process, while retaining sufficient structural strength.

[0011] The linear trench cover provided by this utility model is suitable for being laid on the foundation of a drainage ditch with mortar. The foundation of the drainage ditch includes one or more of brick drainage ditches, precast drainage ditches, or resin drainage ditches.

[0012] Beneficial effects: Compared with the prior art, the advantages of this utility model are:

[0013] (1) Significantly reduced cost: The stone material is directly used for processing, replacing the expensive custom stainless steel cover plate. Furthermore, due to its good structural compatibility, the foundation of the drainage ditch, which is made of lower-cost brick or precast concrete, can be selected, thereby significantly reducing the cost of the entire linear drainage system.

[0014] (2) Simplified construction and improved efficiency: Combining the cover plate with the surface stone reduces the types of materials and installation procedures. The cover plate can be prefabricated (factory-made or processed on-site), and the on-site paving is similar to that of ordinary stone, which significantly shortens the construction cycle and improves construction efficiency.

[0015] (3) Enhanced aesthetics: The material of the cover plate is completely consistent with the surrounding paving stone, without the intervention of different materials (such as stainless steel), forming a unified, continuous and integrated landscape effect.

[0016] (4) Easy maintenance: The cover plate unit can be pried up like an ordinary stone block, making it easy to thoroughly clean and maintain the drainage ditch below, solving the problem of difficult cleaning of existing stainless steel cover plates and facilitating property management.

[0017] (5) Strong compatibility: Since the bottom shape of the cover plate is relatively simple and the material is stone, it can be stably placed on various drainage ditch foundations, such as traditional brick drainage ditches, precast concrete drainage ditches or resin drainage ditches, providing construction units with more economical and flexible choices.

[0018] (6) Easy to promote and apply: The production process (stone cutting and grooving) is simple and reliable, easy for workers to master, and can be produced using the stone and processing equipment commonly used in landscape engineering, which is conducive to its widespread application in various projects.

[0022] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings, but the protection scope of this utility model is not limited to the described embodiments.

[0023] Example 1: As Figure 1 , Figure 2 The prefabricated linear drainage ditch shown is suitable for stone paving in fully underground parking garages. It includes a linear ditch cover, which is constructed from a single piece of standard-sized stone (600mm long, 300mm wide, and 50mm-80mm thick). The stone can be natural stone such as granite or marble, or artificial stone with equivalent properties. The stone has a top surface (the visible surface after installation) and a bottom surface (the surface facing down during installation).

[0024] On the top surface 11, a top drainage groove 2 is provided at the center along the length of the stone (along a 600mm long edge). This top drainage groove 2 is linear and runs through the entire length (or nearly the entire length) of the stone. In this embodiment, the width of the top drainage groove 2 can be designed to be 2cm, and the depth can be designed to be 2cm. This depth is insufficient to penetrate the entire thickness of the stone, but it can be used to collect surface water and form an aesthetically pleasing linear drainage effect.

[0025] Crucially, a bottom through-groove 3 is precisely cut into the bottom surface of the stone at a location that corresponds exactly to the top drainage groove 2. The width of the bottom through-groove 3 is the same as that of the top drainage groove 2, i.e., 2cm. The depth of the bottom through-groove 3 is sufficient to penetrate the stone, from the top drainage groove 2, the bottom, and the remaining thickness of the stone's bottom surface. However, the length of the bottom through-groove 3 is designed to be shorter than that of the top drainage groove 2. For example, if the length of the stone is 600mm and the length of the top drainage groove 2 is close to 600mm, then the length of the bottom through-groove 3 can be designed to be 400mm, located in the center of the stone's length direction. In this way, ungrooved stone portions, i.e., structural connection parts 4, are naturally formed at both ends of the bottom through-groove 3. In this example, the length of each structural connection part 4 is (600mm - 400mm) / 2 = 100mm.

[0026] These two structural connections play a crucial role: they maintain the integrity and structural strength of the stone after grooving, allowing the cover to withstand the loads of pedestrians and light vehicles and preventing breakage due to the through-groove. Simultaneously, water can flow in through the top drainage channel on the top surface and then out through the bottom through-groove on the bottom surface, entering the drainage ditch foundation below.

[0027] Example 2: This example is basically the same as Example 1, except for the change in dimensional parameters. For example, 800mm*400mm stone can be selected, and the width of the top drainage groove 2 can be designed to be 1.5cm or 2.5cm, with the depth adjusted accordingly. The length of the bottom through groove 3 and the length of the structural connection part 4 also need to be adjusted according to the stone size and mechanical calculations. For example, the length of the bottom through groove can be 60%-70% of the total length of the stone, ensuring that the structural connection part 4 has sufficient width (e.g., not less than 50mm, preferably 100mm-150mm). This reflects the flexibility and customizability of this utility model design.

[0028] Example 3: This example emphasizes the installation process. For example... Figure 3 As shown, before laying the cover plate of this utility model, the drainage ditch foundation 5 needs to be constructed according to the design requirements. This drainage ditch foundation 5 can be a traditional brick ditch, a precast concrete ditch, or, under specific requirements, a resin concrete ditch. The cover plate of this utility model has good compatibility with these applications.

[0029] Then, the pre-processed stone cover slabs 1, conforming to the above structural characteristics, are laid on the top edge of the drainage ditch foundation 5 (or on a specially designed support structure) using a mortar layer. By adjusting the thickness of the mortar layer, the elevation of the cover slabs can be precisely controlled to ensure that their top surface 11 is flush with the surrounding stone paving surface, and that the top drainage channels 2 of all cover slabs are aligned in a straight line, ensuring smooth drainage and a neat appearance.

[0030] The core of this invention lies in the creative formation of a self-supporting cover unit that integrates drainage outlets and decorative surface layers by specifically grooving a whole piece of stone on both sides with different lengths. The shallow groove at the top collects water and provides a linear appearance, while the short, continuous groove at the bottom guides water into the drainage ditch below. The ungrooved portion at the bottom (structural connection) ensures the structural strength of the cover. This design abandons the combination of expensive and restrictive metal covers and specific resin grooves, using economical and readily available stone and simple processing techniques to achieve a comprehensive effect of low cost, high efficiency, beautiful appearance, easy maintenance, and strong compatibility. It is particularly suitable for thick stone landscape paving projects with high requirements for cost, aesthetics, and maintenance.

[0031] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
