[0003]

[Problems to be solved by the invention]

 However, since the conventional dust removing apparatus is composed of three members (51, 52, 53), the management and installation of the members are troublesome, and the number of estimates is large. Further, since each of the three members (51, 52, 53) is a plastic product, dirt easily adheres. Further, since the weight of dust is added to the support plate 51 in addition to the weight of the first filter 52 and the second filter 53, the support plate 51 is gradually deformed. In addition, during maintenance, the second filter 53 is screwed down, which makes it difficult to remove it.

[0004]

[Means for Solving the Problems]

 The present invention has been proposed in view of the above, and is a garbage removal device disposed at a rainwater inlet when burying rainwater infiltration products such as seepage wells (measures) and storage seepage wells. Plates with many fine through-holes cut out so that the widened portions of the same width extend on the four sides of the bottom portion are raised substantially vertically, and the side edges are adjacent to the widened portions. Garbage removal for the underground infiltration facility by forming the side of the basin by joining with the side edge of the base, and bending the upper end of each raised wide part outward to form a support part It concerns the device. It is desirable to attach a handle having both ends fixed to the adjacent upper edge at a pair of opposing corners of the upper edge of the basin.

[0005]

[Action]

 The dust removal device of the present invention having the above-described configuration is configured such that a support portion extending in the front-rear and left-right directions is formed at the upper edge of the bucket-shaped basin, and is extremely easy to install because it is a single member. It only needs to be estimated at one point. For example, when a stainless steel punched metal plate is used as a plate material having a large number of fine through holes, it is made of stainless steel and is not easily stained and has high strength. In addition, the handle improves the handleability of the dust removal device itself and also prevents deformation of the box.

[0006]

[Embodiment of the invention]

 The dust removing device of the present invention can be easily manufactured by simply cutting a plate material having a large number of fine through holes, for example, a stainless steel punched metal plate into a predetermined shape, and then appropriately bending and joining the plate material. Further, as the plate material having a large number of fine through holes, in addition to the above stainless steel punched metal plate, a steel material incorporated in a net shape to be integrated can be used in the same manner.

First, as shown in FIG. 2, a stainless-punched metal plate is cut out such that widened portions 2 having the same width are respectively extended on four sides of a substantially square bottom portion 1. A folding line 4 for forming the support portion 3 is added to each widening portion 2 in advance.

Next, the widened portions 2 are raised vertically with respect to the bottom surface portion 1. When the widened portion 2 is started, the support portion 3 may be bent (in this case, downward) in advance.

Then, the side edge of the widened portion 2 that has been raised is joined to the side edge of the adjacent widened portion 2 by welding or the like. As a result, a square 5 whose upper part is open is formed.

After that, the upper edge of each widened portion 2 is bent outward in a substantially horizontal shape to form the support portion 3.

A handle 6 is attached to a pair of opposing corners of the upper edge of the cell 5, and the handle 6 is attached to the adjacent upper edge of the cell 5 so that both ends are fixed. Thus, the dust removing device 7 shown in FIG. 3 is formed.

Next, an example in which the refuse removal device 7 is provided in a rainwater infiltration facility will be described. A water-permeable concrete product made by connecting either concrete products or plastic products, or aggregates with a small amount of binder to form continuous fine voids, which is manufactured as a water-permeable well, etc. The material, shape, physical properties of bending strength, and the like are not limited at all. Therefore, as the rainwater infiltration product in the present invention, a known rainwater infiltration product can be used as it is, and the production method and the method of opening holes and slits may be performed by a known method. Further, the above-mentioned rainwater infiltration products include rainwater storage and infiltration products such as storage infiltration wells for storing and effectively using a certain amount of rainwater. Further, other configurations of the rainwater infiltration facility in the present invention are not particularly limited, and may be formed in any manner.

The rainwater infiltration facility shown in FIG. 3 uses a permeation well (basin) as a rainwater infiltration product, and the dust removal device 7 of the present invention is arranged on the upper surface of the permeation well. In the figure, reference numeral 8 denotes sand, on which a single-grained crushed stone 9 is filled as a filler, and a water-permeable sheet 10 is laid therearound. A bottom cover 12 made of permeable concrete is provided at the center of the bottom plate 11 of the seepage well (cell), and a tubular body 13 forming a side surface is formed on the upper surface of the bottom plate 11 and is placed there. Further above, a concrete cylindrical mass 14 and an edge mass 15 are placed. A receiving portion for receiving the grating 16 is formed on the rim 15. The support portion 3 of the dust removing device 7 of the present invention is placed on this receiving portion, and then the grating 16 is placed thereon. Therefore, the support portion 3 of the dust removing device 7 according to the present invention is stably supported between the grating 16 and the edge lump 14.

The rainwater infiltration facility constructed in this manner can remove dust, plant branches, leaves and the like according to the hole diameter of the punching metal constituting the trash removal device 7, so that the fine voids of the rainwater infiltration product can be removed. It can prevent the obstruction of rainwater and continuously exert the rainwater infiltration function.

The rainwater infiltration facility shown in FIG. 4 uses a storage infiltration well (basin) as a rainwater infiltration product, and the dust removal device 7 of the present invention is disposed on the upper surface of the storage infiltration well. The storage infiltration well (basin) is a storage tank in which the lower part is formed by forming a reinforced concrete layer 18 on the outer peripheral surface of a plastic container 17, the upper part is a tubular permeable concrete side block 19, and the upper surface is further provided with dust removal. It is configured to include an edge lump 21 to which the device 7 and the water-permeable lid 20 are attached. In the periphery of the water-permeable concrete side lump 19, a recycled resource aggregate such as glass cullet is replaced with a bag made of a water-permeable sheet instead of single-grained crushed stone. The sealed substance 22 was filled. In the figure, reference numeral 23 denotes a drain pipe attached so that an edge faces the inside, and 24 denotes backfill soil.

In this rainwater storage and infiltration facility, the rainwater flowing from the surrounding ground surface through the water-permeable lid 20 can be stored in the storage tank 17 by removing relatively large dust with the dust removal device 7. It can be effectively used as a water source in case of water cutoff or fire. Rainwater exceeding the allowable amount flows out of the drainage pipe 23 to a drainage facility as appropriate.

[Effect of the invention]

 As explained above, since the trash removal device for rainwater underground infiltration facilities of the present invention is a single member, installation and construction and maintenance work are extremely easy compared to the conventional trash removal device consisting of multiple members. . You only need one point for quotation. Further, when a stainless steel punched metal plate is used as a plate material having a large number of fine through holes, it is less likely to be stained than a conventional plastic dust removing device and hardly deformed with respect to weight.

Further, when a pair of opposite corners of the upper edge of the basin are provided with grips having both ends fixed to the adjacent upper edge, handleability in installation and maintenance work is improved. Deformation of the portion and the like are more unlikely to occur.
