Description

Technical Field

[0001] This utility model relates to the field of plastic drainage board technology, specifically an environmentally friendly composite 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] In actual use, when the conical protrusions are installed facing upwards, the filter geotextile at the top of the conical protrusions is squeezed by the soil above. The bottom of the filter geotextile in the middle area between two adjacent conical protrusions is unsupported and is prone to sinking, which leads to blockage of the channel between the conical protrusions. To avoid channel blockage, an environmentally friendly composite plastic drainage board is provided. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly composite plastic drainage board in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly composite 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 to the bottom of the base plate. A support component is provided on the conical protrusions. When the conical protrusions are arranged upward, the support component is used to provide auxiliary support for the filter geotextile laid on the top of the conical protrusions.

[0006] The support assembly includes a connecting crossbar, a mountain-shaped connecting bar, and a supporting crossbar;

[0007] The connecting crossbar is fixed to the bottom of multiple conical protrusions distributed horizontally, and the mountain-shaped connecting strip is fixed to the top of multiple connecting crossbars distributed horizontally. Multiple mountain-shaped connecting strips are evenly arranged along the horizontal direction of the connecting crossbars.

[0008] The support crossbars are fixed to multiple horizontally distributed mountain-shaped connecting strips. Multiple support crossbars are evenly arranged along the longitudinal direction of the mountain-shaped connecting strips. The grid structure formed by the mountain-shaped connecting strips and the support crossbars is used to provide auxiliary support for the sinking geotextile.

[0009] As a further improvement of this utility model: the mountain-shaped connecting strip, the supporting horizontal strip and the conical protrusion are staggered, and the mountain-shaped connecting strip and the supporting horizontal strip do not contact the lower surface of the substrate.

[0010] As a further embodiment of this utility model: the bottom of the conical protrusion is formed with a straight groove, the straight groove extends through both sides of the conical protrusion, and the connecting crossbar is engaged with the inside of the straight groove.

[0011] As a further improvement of this utility model: the thickness of the connecting crossbar matches the depth of the straight groove, and the width of the connecting crossbar matches the width of the inner wall of the straight groove.

[0012] As a further embodiment of this utility model: the substrate, the conical protrusion, and the straight groove are integrally formed by injection molding, and the connecting crossbar, the mountain-shaped connecting bar, and the supporting crossbar are integrally formed by injection molding.

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

[0014] By setting up support components, when the conical protrusions are distributed upwards, the connecting crossbars can provide auxiliary support for the filter geotextile, which can effectively reduce the sinking of the filter geotextile. When the filter geotextile sinks, the grid structure composed of the mountain-shaped connecting strips and the support crossbars can provide support for the sinking filter geotextile, preventing the sinking filter geotextile from contacting the substrate, so that there is still space between the sinking filter geotextile and the substrate, and the drainage channel remains unobstructed.

[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, an environmentally friendly composite 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 are fixed to the bottom of the base plate 101 in a matrix arrangement. A support component 2 is provided on the conical protrusions 102. When the conical protrusions 102 are distributed upwards, the support component 2 is used to provide auxiliary support for the filter geotextile laid on the top of the conical protrusions 102.

[0022] Support component 2 includes a connecting crossbar 201, a mountain-shaped connecting bar 202, and a supporting crossbar 203;

[0023] The connecting crossbar 201 is fixed to the bottom of multiple conical protrusions 102 distributed horizontally, and the mountain-shaped connecting strip 202 is fixed to the top of multiple connecting crossbars 201 distributed horizontally. Multiple mountain-shaped connecting strips 202 are evenly arranged along the horizontal direction of the connecting crossbars 201.

[0024] The support crossbar 203 is fixed on multiple horizontally distributed mountain-shaped connecting bars 202. Multiple support crossbars 203 are evenly arranged along the longitudinal direction of the mountain-shaped connecting bars 202. The grid structure formed by the mountain-shaped connecting bars 202 and the support crossbars 203 is used to provide auxiliary support for the sinking filter geotextile.

[0025] The mountain-shaped connecting strip 202, the supporting horizontal strip 203 and the conical protrusion 102 are staggered, and the mountain-shaped connecting strip 202 and the supporting horizontal strip 203 do not contact the lower surface of the substrate 101.

[0026] In this embodiment: When using drainage board 1, the following two installation modes can be used depending on site requirements:

[0027] The first type is with the conical boss 102 facing upwards. In this case, a filter geotextile will be laid on the top of the conical boss 102. In this case, the filter geotextile is prone to sinking due to the squeezing force from the soil. The connecting crossbar 201 can provide auxiliary support for the filter geotextile, which can effectively reduce the sinking phenomenon. When the filter geotextile sinks, the grid structure formed by the mountain-shaped connecting bar 202 and the supporting crossbar 203 can provide support for the sinking filter geotextile, preventing the sinking filter geotextile from contacting the substrate 101, so that there is still space between the sinking filter geotextile and the substrate 101, so that the drainage channel remains unobstructed.

[0028] The second type is with the conical boss 102 facing downwards. In this case, the grid structure formed by the mountain-shaped connecting strip 202 and the supporting horizontal strip 203 is not in contact with the ground structure and will not interfere with the drainage. It should also be noted that the long side of the connecting horizontal strip 201 is parallel to the drainage direction, thus ensuring smooth drainage.

[0029] Please refer to this carefully. Figures 1-4 The bottom of the conical protrusion 102 is formed with a straight groove 103, which passes through both sides of the conical protrusion 102, and the connecting crossbar 201 is engaged with the inside of the straight groove 103.

[0030] The thickness of the connecting bar 201 matches the depth of the straight groove 103, and the width of the connecting bar 201 matches the width of the inner wall of the straight groove 103.

[0031] The substrate 101, conical protrusion 102, and straight groove 103 are integrally formed by injection molding, and the connecting crossbar 201, mountain-shaped connecting bar 202, and supporting crossbar 203 are integrally formed by injection molding.

[0032] In this embodiment: the drainage board 1 and the support component 2 are each injection molded, and their production process is the same as that of existing plastic drainage boards. Then, the support component 2 and the drainage board 1 are bonded or ultrasonically welded together. The assembly process is simple and easy to promote and produce.

[0033] The lower surface of the fixed connecting strip 201 is flush with the lower surface of the conical protrusion 102, which will not affect the flatness of the drainage board 1.

[0034] 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.
