Description

Technical Field

[0001] The utility model belongs to the technical field of drainage boards, and in particular relates to an anti-clogging drainage board. Background Art

[0002] It is widely used in various civil engineering projects, especially in areas where effective drainage systems are required, such as roof greening, underground garage roofs, road projects, etc., which helps to improve the drainage efficiency of the project and protect the structure. However, in the field of greening and water management, due to irrigation and precipitation, drainage boards are required to meet the requirements of drainage while taking into account the ability to store water. Utility Model Content

[0003] The purpose of the utility model is to provide an anti-clogging drainage board to achieve the effect of drainage and water storage in view of the above-mentioned existing technical problems.

[0004] In view of this, the utility model provides an anti-clogging drainage board, including a mounting plate arranged at the bottom, a drainage board body, a support layer, a filter layer, and a protective layer are sequentially arranged on the upper part of the mounting plate, a flow channel for water to flow downward is arranged on the drainage board body, a water storage structure is arranged on one side of the drainage board body against the mounting plate, and a drainage channel is formed between the drainage board body and the mounting plate.

[0005] In the present technical scheme, a filling soil layer is arranged on the top of the protective layer, and vegetation is planted in the soil layer. The plant roots take root in the soil layer. When precipitation and irrigation occur, water flows downward from the soil layer, the protective layer and the filter layer to the drainage board body in sequence. The water flow is collected by the water storage structure on the drainage board body, or directly flows from the flow channel arranged on the drainage board to the drainage channel formed between the drainage board body and the mounting plate to leave. When the water storage structure on the drainage board is full of water, the water flow can only leave from the flow channel and the drainage channel in sequence. The water accumulated in the water storage structure can act on the plant roots in the soil layer through the filter layer and the protective layer by capillary action, infiltration, evaporation and the like, thereby meeting the water demand for plant growth.

[0006] In the above technical solution, further, the water storage structure includes a plurality of water storage units arranged in an array on the drainage plate body on one side of the mounting plate, the water storage unit is a cylinder with an opening upward, and the cylinder is in contact with the mounting plate.

[0007] In the present technical solution, the water storage unit can not only play the role of supporting the drainage board body on the mounting plate, but also accumulate water during precipitation and irrigation. The water accumulated in the water storage unit can act on the plant roots in the soil layer through the filtration layer and the protective layer through capillary action, infiltration, evaporation, etc., to meet the water needs of plant growth.

[0008] In the above technical solution, the flow channel includes a first channel and a second channel arranged on the main board of the drainage board body.

[0009] In the above technical solution, further, the first channel is a through hole arranged between the openings of the two water storage units at diagonal positions, and the second channel is a strip-shaped opening arranged between the openings of the two water storage units.

[0010] In the present technical solution, the setting of the first channel and the second channel can drain the water that penetrates from above more quickly, and the water flows into the drainage channel faster, which helps to prevent possible water accumulation problems. The rapid discharge of excess water helps to maintain suitable soil moisture and promote the healthy growth of plants. Long-term water accumulation may cause additional loads and affect the structural integrity.

[0011] In the above technical solution, further, a limiting groove is provided on the mounting plate corresponding to the abutting water storage unit.

[0012] In this technical solution, it is easy to install and can play a better supporting role.

[0013] In the above technical solution, further, the support layer is a metal mesh plate, which can play a good supporting role for the filter layer.

[0014] In the above technical solution, further, the filter layer is a geotextile.

[0015] In the above technical solution, further, the protective layer includes a frame, support nets are arranged on both sides of the frame, and sand and gravel are filled between the two layers of support nets.

[0016] In this technical solution, a protective layer is set to prevent plant roots from directly piercing the geotextile due to their hydrotropism, which would cause blockage in the drainage of the drainage board. The support net and the internal sand and gravel filling can serve as a physical barrier to prevent direct contact between plant roots and the geotextile, thereby providing good protection for the geotextile and ensuring the water permeability without affecting the drainage and water storage effect of the drainage board.

[0017] The beneficial effects of the utility model are:

[0018] 1. When precipitation, irrigation, etc. occur, water flows downward from the soil layer, protective layer, and filter layer to the drainage board body in turn, and the water flow is collected by the water storage structure on the drainage board body, or directly flows from the flow channel set on the drainage board to the drainage channel formed between the drainage board body and the mounting plate. When the water storage structure on the drainage board is full of water, the water flow can only leave from the flow channel and the drainage channel in turn. The water accumulated in the water storage structure can act on the plant roots in the soil layer through the filter layer and the protective layer through capillary action, infiltration, evaporation, etc., to meet the water demand of plant growth;

[0019] 2. The setting of the first channel and the second channel can drain the water that penetrates from above more quickly. The water flows into the drainage channel faster, which helps to prevent possible water accumulation problems. The rapid discharge of excess water helps to maintain appropriate soil moisture and promote the healthy growth of plants. Long-term water accumulation may cause additional loads and affect the structural integrity.

[0020] 3. Set up a protective layer to prevent plant roots from directly piercing the geotextile due to their hydrotropism, which would cause the drainage of the drainage board to be blocked. The support net and the internal sand and gravel filling can serve as a physical barrier to prevent direct contact between plant roots and the geotextile, which can provide good protection for the geotextile and ensure the water permeability without affecting the drainage and water storage effect of the drainage board.

[0032] Embodiment 1:

[0033] like Figure 1-4 As shown, this embodiment provides an anti-clogging drainage board, including a mounting plate 1 arranged at the bottom, a drainage board body 2, a support layer 3, a filter layer 4, and a protective layer 5 are arranged in sequence on the upper part of the mounting plate 1, a flow channel 6 for water to flow downward is arranged on the drainage board body 2, a water storage structure 7 is arranged on one side of the drainage board body 2 against the mounting plate 1, and a drainage channel 8 is formed between the drainage board body 2 and the mounting plate 1. A filling soil layer is arranged on the top of the protective layer 5, and vegetation is planted in the soil layer. The roots of the plants take root in the soil layer. When precipitation, irrigation, etc. occur, water flows downward from the soil layer, the protective layer 5, and the filter layer 4 to the drainage board body 2 in sequence. The water flow is collected by the water storage structure 7 on the drainage board body 2, or directly flows from the flow channel 6 arranged on the drainage board to the drainage channel 8 formed between the drainage board body 2 and the mounting plate 1 to leave. When the water storage structure 7 on the drainage board is full of water, the water flow can only leave from the flow channel 6 and the drainage channel 8 in sequence. The water accumulated in the water storage structure 7 can act on the plant roots in the soil layer through the filter layer 4 and the protective layer 5 by capillary action, infiltration, evaporation, etc., so as to meet the water demand for plant growth.

[0034] like Figure 1 and Figure 2 As shown, the water storage structure 7 includes a plurality of water storage units 9 arranged in an array on one side of the drainage board body 2 located on the mounting plate 1. The water storage unit 9 is a cylinder with an opening upward, and the cylinder is in contact with the mounting plate 1. The water storage unit 9 can not only support the drainage board body 2 on the mounting plate 1, but also store water during precipitation and irrigation. The water stored in the water storage unit 9 can act on the plant roots in the soil layer through the filter layer 4 and the protective layer 5 through capillary action, infiltration, evaporation, etc., to meet the water demand of plant growth.

[0035] like Figure 2 As shown, the flow channel 6 includes a first channel 10 and a second channel 11 arranged on the main board 12 of the drainage board body 2. The first channel 10 is a through hole arranged between the openings of the two water storage units 9 at the diagonal positions, and the second channel 11 is a strip-shaped opening arranged between the openings of the two water storage units 9. The arrangement of the first channel 10 and the second channel 11 can discharge the water that penetrates from above more quickly, and the water flows into the drainage channel 8 more quickly, which helps to prevent possible water accumulation problems. Rapid discharge of excess water helps to maintain appropriate soil moisture and promote healthy growth of plants. Long-term water accumulation may cause additional loads and affect structural integrity.

[0036] like Figure 4 As shown, the mounting plate 1 is provided with a limiting groove 13 corresponding to the abutting water storage unit 9, which is convenient for installation and can play a better supporting role.

[0037] The support layer 3 is a metal mesh plate, which can provide good support for the filter layer 4 .

[0038] The filter layer 4 is a geotextile.

[0039] like Figure 3 As shown, the protective layer 5 includes a frame 16, and support nets 14 are arranged on both sides of the frame 16, and sand and gravel 15 are filled between the two layers of support nets 14. The protective layer 5 is provided to prevent the plant roots from directly piercing the geotextile due to their hydrotropism, resulting in the blockage of the drainage of the drainage board body 2.
