Description

Technical Field

[0001] This utility model relates to the field of drainage board technology, specifically a multi-channel plastic drainage board. Background Technology

[0002] Plastic drainage boards are made of polystyrene (HIPS) or polyethylene (HDPE) plastic base plates, which are stamped to form conical protrusions or stiffening ribs (or hollow cylindrical porous shapes). During use, a layer of filter geotextile is glued to the top surface of the conical protrusions to prevent soil particles from passing through, thereby avoiding blockage of the drainage channels and ensuring smooth drainage.

[0003] However, in actual use, there is a phenomenon where the filter geotextile sinks due to excessive compression, causing blockage of the drainage channels. Based on this, in order to maintain the drainage effect even when the filter geotextile sinks, a multi-channel plastic drainage board is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-channel plastic drainage board in order to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-channel plastic drainage board, comprising a drainage board composed of a base plate and conical protrusions, wherein multiple conical protrusions are provided and the multiple conical protrusions are arranged in a matrix and fixed on the top of the base plate; the drainage board further comprises capillary drainage channels and an upper partition plate.

[0006] The capillary drainage groove is formed on the side of the conical protrusion and extends through the top of the conical protrusion. The upper partition is fixed to the outside of the multiple capillary drainage grooves and distributed above the substrate. The area from the upper surface of the upper partition to the upper surface of the conical protrusion is the first drainage channel. The area between the upper partition and the substrate is used to form the second drainage channel. The capillary drainage groove is used to introduce water in the first drainage channel into the second drainage channel.

[0007] As a further embodiment of this utility model: the base plate and the conical protrusion are aligned around their perimeters, and the base plate and the conical protrusion are respectively fixed with L-shaped side edges and inverted L-shaped side edges on their two sides, and the base plate and the conical protrusion are respectively fixed with L-shaped end edges and inverted L-shaped end edges at their two ends.

[0008] Two adjacent drainage boards distributed horizontally and longitudinally are fixed by overlapping and heat-melting L-shaped sides and inverted L-shaped sides, and two adjacent drainage boards distributed horizontally and laterally are fixed by overlapping and heat-melting L-shaped ends.

[0009] As a further embodiment of this utility model: the interior of the L-shaped side and the inverted L-shaped side is formed with drainage holes, the drainage holes are connected to the second drainage channel, and the drainage holes penetrate through both ends of the L-shaped side and the inverted L-shaped side. The two adjacent L-shaped sides and the inverted L-shaped side are connected by a connecting pipe inserted into the drainage hole.

[0010] As a further embodiment of this utility model: one end of the L-shaped side and the inverted L-shaped side is flush with the end face of the L-shaped end, and the end face of the inverted L-shaped end protrudes beyond the other end of the L-shaped side and the inverted L-shaped side.

[0011] As a further embodiment of this utility model: a plurality of capillary drainage grooves are formed on a single conical protrusion, and the plurality of capillary drainage grooves are evenly distributed in a ring around the center of the conical protrusion.

[0012] The bottom end of the capillary drainage channel is flush with the upper surface of the substrate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By setting up a drainage board with capillary drainage channels and an upper partition, the drainage board has two drainage channels. It mainly relies on the first drainage channel for drainage. When the filter geotextile sinks and causes the first drainage channel to become blocked, the water in the blocked area can be discharged into the second drainage channel through the capillary drainage channels and then discharged through the second drainage channel, thus ensuring smooth drainage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 In this embodiment of the utility model, a multi-channel plastic drainage board includes a drainage board 1 composed of a base plate 101 and conical protrusions 102. Multiple conical protrusions 102 are provided, and the multiple conical protrusions 102 are fixed on the top of the base plate 101 in a matrix distribution. The drainage board 1 also includes capillary drainage grooves 103 and upper partitions 104.

[0022] The capillary drainage channel 103 is formed on the side of the conical protrusion 102 and extends through the top of the conical protrusion 102. The upper partition 104 is fixed to the outside of the multiple capillary drainage channels 103 and distributed above the substrate 101. The area from the upper surface of the upper partition 104 to the upper surface of the conical protrusion 102 is the first drainage channel. The area between the upper partition 104 and the substrate 101 is used to form the second drainage channel. The capillary drainage channel 103 is used to introduce water in the first drainage channel into the second drainage channel.

[0023] Multiple capillary drainage grooves 103 are provided on a single conical protrusion 102, and the multiple capillary drainage grooves 103 are evenly distributed in a ring around the center of the conical protrusion 102.

[0024] The bottom end of the capillary drainage groove 103 is flush with the upper surface of the substrate 101.

[0025] In this embodiment: When this drainage plate 1 is in use, it has two drainage channels: the area from the upper surface of the upper partition plate 104 to the upper surface of the conical protrusion 102 is the first drainage channel, and the area between the upper partition plate 104 and the substrate 101 is used to form the second drainage channel.

[0026] In daily use, drainage mainly relies on the first drainage channel, and its drainage principle is the same as that of drainage boards commonly found on the market.

[0027] When the filter geotextile sinks and causes blockage of the first drainage channel, the water in the blocked area can be discharged into the second drainage channel through the capillary drainage channel 103, and then discharged through the second drainage channel, thus ensuring smooth drainage.

[0028] Please refer to this carefully. Figures 1-4The substrate 101 and the conical protrusion 102 are aligned around their perimeters, and L-shaped side 2 and inverted L-shaped side 3 are fixed to the two sides of the substrate 101 and the conical protrusion 102, respectively. L-shaped end edge 5 and inverted L-shaped end edge 6 are fixed to the two ends of the substrate 101 and the conical protrusion 102, respectively.

[0029] Two adjacent drainage boards 1 distributed horizontally and longitudinally are fixed by overlapping and heat-melting the L-shaped side 2 and the inverted L-shaped side 3. Two adjacent drainage boards 1 distributed horizontally and laterally are fixed by overlapping and heat-melting the L-shaped end 5 and the inverted L-shaped end 6.

[0030] Drainage holes 4 are formed inside the L-shaped side 2 and the inverted L-shaped side 3. The drainage holes 4 are connected to the second drainage channel and pass through both ends of the L-shaped side 2 and the inverted L-shaped side 3. The two adjacent L-shaped side 2 and the inverted L-shaped side 3 distributed laterally are connected by a connecting pipe inserted into the drainage hole 4.

[0031] In this embodiment: the cooperation of L-shaped side 2, inverted L-shaped side 3, L-shaped end 5, and inverted L-shaped end 6 makes the second drainage channel completely isolated and independent from the first drainage channel, and facilitates the splicing and fixing of the drainage board 1.

[0032] In addition, by inserting the connecting pipe into the corresponding drain hole 4, the horizontally distributed second drain channels are connected and circulated in sequence, thereby ensuring the smooth drainage of the second drain channels.

[0033] Please refer to this carefully. Figures 1-3 One end of L-shaped side 2 and inverted L-shaped side 3 is flush with the end face of L-shaped end 5, and the end face of inverted L-shaped end 6 protrudes beyond the other end of L-shaped side 2 and inverted L-shaped side 3.

[0034] In this embodiment, this structure is used to achieve a smooth splicing of the inverted L-shaped end edge 6 and the L-shaped end edge 5, so that the splicing of the L-shaped side edge 2 and the inverted L-shaped side edge 3 does not interfere with the splicing of the L-shaped end edge 6 and the L-shaped end edge 5.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
