Description

Technical Field

[0001] The utility model relates to the technical field of drainage structures, in particular to a drainage ditch structure capable of filtering water for a material field. Background Art

[0002] In some large material yards, a long drainage ditch is usually set up next to the stockpile. The water in the stockpile can flow into the drainage ditch for collection and then be discharged from the material yard through the drainage ditch. The drainage ditch needs to be made into an open ditch. After long-term use, the stockpile particles will fall into the drainage ditch; when the stockpile gathers to a certain extent, it is easy to cause the drainage ditch to be blocked. To prevent the stockpile from scattering in, certain filtering measures need to be taken above the drainage ditch to prevent the stockpile particles from entering the drainage ditch and clogging it. This measure can prevent the stockpile from falling in without affecting the flow of water into the drainage ditch.

[0003] One of the prior arts provides a filtering slow-release drainage ditch structure. The drainage ditch structure has a cover plate above the drainage ditch and a filter layer composed of sand and gravel below, and is mainly used in the drainage of sponge cities in the municipal field.

[0004] However, after analysis, the inventor found that the gutter structure cannot be applied in the field of material yards. The main reasons are as follows: the upper cover plate of the gutter structure has no filtering effect, and the pile of materials will enter the gutter and cause the gutter to be blocked. In addition, due to the narrow width of the gutter, it is not easy to clean when the bottom is blocked.

[0005] The second prior art provides a drainage device for a wet pre-selection waste rock bin in a ore dressing plant.

[0006] The drainage device uses crushed stone floor as the first layer of filtration. In the current material yard projects, the floor is made of reinforced concrete, and crushed stone floor cannot be used. Because the crushed stone in the crushed stone floor is easy to mix with the pile of materials in the material yard, affecting the use of the pile. In addition, environmental protection requires that the water in the pile must be discharged into the drainage ditch and must not seep into the floor to pollute the environment. Therefore, only the filter layer can be set inside the drainage ditch, and the amount of crushed stone is also small, which saves costs.

[0007] The drainage device is equipped with geotextile on the cover plate for filtering. The filter layer on the top of the drainage ditch in the raw material field is easily clogged and needs to be cleaned frequently. During cleaning, the coarse sand layer on the top of the drainage ditch is shoveled away with a crane. If geotextile is used, the crane will damage the geotextile during operation. When restoring, the geotextile needs to be laid again, which increases the maintenance process.

[0008] The drainage device uses large stones to cover the inside of the drainage ditch, which requires a large amount of stones and occupies the internal space of the drainage ditch, thus having a great influence on the drainage volume.

[0009] Therefore, it is necessary to provide a drainage ditch structure capable of filtering water for a material field to solve at least one of the above problems. Utility Model Content

[0010] In view of the defects existing in the prior art, the embodiment of the utility model provides a water-filtering drainage ditch structure for a material yard, which can prevent pile particles from entering the drainage ditch and allow water to flow into the drainage ditch.

By setting a support plate in the drainage ditch and setting a filter structure between the upper surface of the support plate and the floor elevation, the filter structure and the support plate can cooperate to prevent the stockpile particles from entering the drainage ditch and allow water to flow into the drainage ditch. Since the filter structure is only set inside the local drainage ditch body between the upper surface of the support plate and the floor elevation, the filter structure requires less material as a whole, which is conducive to cost control. The filter material can be selected from three layers of filter layers with decreasing sizes from bottom to top. The particle size of the upper filter layer is much smaller than the stockpile in the material yard, and the height is located below the stockpile, so it will not be mixed with the stockpile in the material yard, thereby not affecting the normal use of the stockpile. In addition, the present application can achieve the filtering effect by laying stones of different particle sizes in order from bottom to top, and it is convenient for maintenance.

[0043] The utility model provides a drainage ditch structure capable of filtering water for a material field, which can prevent stockpiled particles from entering the drainage ditch and allow water to flow into the drainage ditch. In addition, the utility model has advantages in environmental protection, cost control, and maintenance convenience.

[0044] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 In the implementation manner of the present application specification, a drainage ditch structure for a material field that can filter water is provided, and the drainage ditch structure for a material field that can filter water may include: a drainage ditch body 1 with an open end at the top, and the top elevation of the drainage ditch body 1 is consistent with the floor elevation; the drainage ditch body 1 has a bottom wall and a side wall, and a support portion 2 is provided at a predetermined position of the side wall; a support plate 3, and the support plate 3 is overlapped on the support portion 2, and the support plate 3 is a porous hollow structure; a filtering structure is arranged between the support plate 3 and the open end, and the filtering structure includes from bottom to top: a first filter layer 41, a second filter layer 42 and a third filter layer 43, the first filter layer 41 includes a plurality of first filter media with a first size, the second filter layer 42 includes a plurality of second filter media with a second size, and the third filter layer 43 includes a plurality of third filter media with a third size, and the first size, the second size and the third size decrease in sequence.

[0045] In the implementation manner of the present application, the drainage ditch structure capable of filtering water for the material field mainly comprises: a drainage ditch body 1, a support plate 3 and a filtering structure.

[0046] In this embodiment, the top elevation of the drainage ditch body 1 is consistent with the floor elevation. The drainage ditch body 1 can be a groove opened downward from the floor elevation. The top of the drainage ditch body 1 is an open end. The drainage ditch body 1 has a bottom wall and a side wall extending from the bottom wall to the top open end. The structure of the side wall can be a vertical side wall perpendicular to the horizontal plane, or a side wall with a certain inclination angle, or a side wall with a certain structure.

[0047] In this embodiment, a support portion 2 for supporting the support plate 3 is provided at a predetermined position of the side wall.

[0048] like Figure 2As shown, for example, in some embodiments, the drainage ditch body 1 is a reinforced concrete structure, the supporting portion 2 is a boss formed on the side wall, and the boss is integrally formed with the drainage ditch body 1.

[0049] In this embodiment, when the drainage ditch body 1 is a reinforced concrete structure, a boss can be provided on the side wall by an integral molding method, and the boss can be used to form a supporting portion 2 that supports the supporting plate 3.

[0050] like Figure 1 As shown, in other embodiments, when the side wall is not provided with a boss structure by an integral molding method, the support portion 2 for supporting the support plate 3 can be provided by other methods. For example, the support portion 2 can be a boss provided from the bottom wall upwardly in contact with the side wall. Specifically, the boss can be a plain concrete boss.

[0051] Of course, the specific setting method of the boss can also be other methods and is not limited to the above description. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0052] In this embodiment, the support plate 3 is overlapped on the support part 2 to support the upper filter structure. The setting position of the support part 2 can be determined according to the height of the filter structure, and this application does not make any specific limitation here.

[0053] The support plate 3 is a porous hollow structure. The support plate 3 is a porous hollow structure that can not only be used to support the upper filtering structure, but also can guide the water filtered by the filtering structure to the drainage ditch below.

[0054] like Figure 4 As shown, specifically, the support plate 3 can be a galvanized steel grating plate, and the support plate 3 includes flat steels 32 and cross bars 31 that are staggered horizontally and vertically, and the spacing between the flat steels 32 and the cross bars 31 is not greater than 150 mm.

[0055] The galvanized steel grating plate includes horizontally and vertically staggered flat steels 32 and crossbars 31. The spacing between two adjacent flat steels 32 is not more than 150 mm, and the spacing between two adjacent crossbars 31 is not more than 150 mm. The optimal spacing is 50×50. The height of the bearing flat steel 32 is determined by the span, and the minimum height is not less than 30 mm. The galvanized steel grating plate can ensure that the support plate 3 has sufficient strength while achieving water repellency, and has high reliability during use.

[0056] Or, if Figure 3As shown, the support plate 3 may be a concrete cover plate, and a long strip-shaped opening 30 is opened on the support plate 3. The width of the opening 30 is not greater than 50 mm, and the spacing between the openings 30 is 200 mm.

[0057] When the support plate 3 is a concrete cover plate, the concrete cover plate may include a rectangular plate body, on the surface of which a plurality of long strip holes 30 arranged in an array are provided. The size of the hole 30 may be adapted according to the size of the upper filter layer in contact with the hole 30, at least to ensure that the filter medium in direct contact with the upper surface of the support plate 3 will not leak out from the hole 30 of the support plate 3.

[0058] A filter structure is provided between the support plate 3 and the open end (from the support plate 3 in the drainage ditch to the position flush with the ground elevation). The filter structure includes from bottom to top: a first filter layer 41, a second filter layer 42 and a third filter layer 43. The first filter layer 41 includes a plurality of first filter media with a first size, the second filter layer 42 includes a plurality of second filter media with a second size, and the third filter layer 43 includes a plurality of third filter media with a third size, and the first size, the second size and the third size decrease in sequence. Among them, the first size is not less than 150 mm; the second size is not less than 20 mm, and the third size is between 0.5 mm and 2 mm. Among them, the first size, the second size and the third size can be the particle size of the corresponding filter medium. Of course, the specific definitions of the above-mentioned first size, the second size and the third size can be different according to the form of the corresponding filter medium.

[0059] By arranging a filtering structure at a position where the support plate 3 in the drainage ditch is flush with the ground elevation, the piled materials can be prevented from falling into the drainage ditch while not affecting the water flowing into the drainage ditch.

[0060] like Figure 1 As shown, in one embodiment, the first filter layer 41 is a block stone filter layer, the second filter layer 42 is a pebble filter layer, and the third filter layer 43 is a coarse sand filter layer.

[0061] In this embodiment, the first filter layer 41 may be a block stone filter layer, which may include a plurality of blocks of stone. The plurality of blocks of stone are uniformly filled on the upper surface of the support plate 3 to form a block stone filter layer with a certain height. Specifically, the height of the block stone filter layer may be comprehensively determined according to the size of the block stone, etc., and the present application does not make any specific limitation here.

[0062] The second filter layer 42 may be a pebble filter layer, which may include a plurality of pebbles. The plurality of pebbles are uniformly filled on the upper surface of the first filter layer 41 to form a pebble filter layer with a certain height. Specifically, the height of the pebble filter layer may be comprehensively determined according to the size of the pebbles, etc., and the present application does not make any specific limitation here.

[0063] The third filter layer 43 may be a coarse sand filter layer, which may include a plurality of coarse sands. The plurality of coarse sands are uniformly filled on the upper surface of the second filter layer 42 to form a coarse sand filter layer with a certain height. Specifically, the height of the coarse sand filter layer may be comprehensively determined according to the size of the coarse sands, etc., and the present application does not make any specific limitation here.

[0064] like Figure 2 As shown, in another embodiment, the first filter layer 41 is a brick layer, the second filter layer 42 is a pebble filter layer, and the third filter layer 43 is a coarse sand filter layer.

[0065] When the first filter layer 41 is a brick layer, the brick layer may include at least one layer of rectangular bricks arranged at intervals, and the distance between two adjacent bricks is smaller than the second size, so as to prevent pebbles from entering the gap between two adjacent bricks and affecting water flow.

[0066] In a specific embodiment, the brick is a standard solid brick, and the size of the standard solid brick is 240mm×115mm×53mm. The above size is the conventional size of solid bricks. When the solid brick adopts the above conventional size, it is beneficial to control the cost without the need for additional mold opening and customization.

[0067] Of course, the brick can also be in the form of a hollow brick, and the size of the brick is not limited to the above examples. Inspired by the technical essence of this application, technicians in the relevant field may also make other changes, but as long as the functions and effects achieved are the same or similar to those of this application, they should be included in the protection scope of this application.

[0068] The embodiment of the present application provides a drainage ditch structure for filtering water in a material yard. By setting a support plate 3 in the drainage ditch and setting a filtering structure between the upper surface of the support plate 3 and the floor elevation, the filtering structure and the support plate 3 can be used to prevent the stockpile particles from entering the drainage ditch and allow water to flow into the drainage ditch. Since the filtering structure is only arranged inside the local drainage ditch body 1 between the upper surface of the support plate 3 and the floor elevation, the material required for the filtering structure is relatively small as a whole, which is conducive to cost control. The filtering material can be selected from three layers of filtering layers with decreasing sizes from bottom to top. The particle size of the upper filtering layer is much smaller than the stockpile in the material yard, and the height is located below the stockpile, so it will not be mixed with the stockpile in the material yard, thereby not affecting the normal use of the stockpile. In addition, the present application can achieve the filtering effect and facilitate maintenance by laying stones of different particle sizes in order from bottom to top.

[0069] It should be noted that, in the description of this application, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0070] The above-mentioned various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0071] The above are only a few embodiments of the present invention. Although the embodiments disclosed by the present invention are as above, the contents are only embodiments adopted for facilitating the understanding of the present invention and are not used to limit the present invention. Any technician in the technical field to which the present invention belongs can make any modification and change in the form and details of the implementation without departing from the spirit and scope disclosed by the present invention, but the scope of patent protection of the present invention shall still be subject to the scope defined by the attached claims.
