Abstract

The present invention relates to an infiltration bucket to collect rainwater to drain the rainwater or to make the rainwater permeate into the ground and, more specifically, relates to an infiltration bucket wherein a diffusion mat is bonded to an outer side of a main body cylinder to be integrated in order to facilitate an installation and reduce costs by eliminating or reducing a use of crushed stones.

Description

A infiltration bucket with diffusion-mat

The present invention relates to an infiltration barrel for collecting and draining rainwater and infiltrating the infiltration basin. More particularly, the present invention relates to an infiltration barrel for collecting rainwater, The present invention relates to a diffusion mat integrated infiltration barrel which can reduce or save costs by eliminating or reducing the cost.

In recent years, along with urban development, the pavement of the ground surface is rapidly proceeding. Pavement on the surface of the ground increases the runoff of rainwater and reduces the number of underground water penetration, resulting in various groundwater faults such as depletion of groundwater, settlement of ground, and salinization due to reverse osmosis of seawater. In addition, the basal flow rate of the river is usually reduced to pollute the water quality, and in the case of rainfall, the flow rate of the river increases to cause flood.

Accordingly, porous infiltration troughs have been used to reduce the runoff of rainwater and restore the rainwater to natural circulation as much as possible. That is, the conventional rainwater infiltration device 35 includes the infiltration barrel 1. This infiltration cistern 1 provides a space for infiltrating the initial storm or the like that has flowed into the inflow pipe 2 at the time of rainfall. The penetration trough (1) is made of a concrete spot or a synthetic resin such as polypropylene. The infiltration cylinder (1) is provided with an inflow pipe (2) and an outflow pipe (3).

16, the penetration trough 1 is provided with a crush stone 5 around the penetration trough 1 so that the infiltrated rainwater can penetrate well into the ground, and when the fine trowel and the like are introduced from the outside, So that the outside of the crushed stone 5 is covered with the water permeable sheet 6. The lowermost end of the infiltration cylinder 1 is provided with a sand 7 so that the penetration effect of the crushed stone 5 can be enhanced.

However, since a large amount of crushed stone 5 is filled around the permeation cylinder 1, the workability is degraded. That is, since it takes a long time to transport and charge the crushed stones 5, the construction time is lengthened and the construction cost is increased due to the prolonged construction. In addition, dust is generated during the filling of the crushed stones 5, and complaints are generated. Also, if the crushed stones 5 are uneven and sharp, the water permeable sheet 6 tends to be torn, and when the soil flows into the torn gap, the holes become clogged and the gravels enter and the equipment is easily broken and the service life is shortened. In addition, the soil collapses due to volumetric change due to filling up the pores of the crushed stone (5), and defects often occur after construction. Particularly, since the crushed stone 5 has a low porosity, the infiltration treatment capacity per unit volume is small. Therefore, there is a problem that the entire required land area is increased.

At this time, the diffusion mat 30 is adhered to the outer surface of the body case 10 by using an adhesive material, or the diffusion mat 30 is passed through the fixing pin 18 embedded in the body case 10 The tip of the fixing pin 18 can be bent and fixed.

As shown in FIG. 2, the diffusion mat 30 is a bundle of plastic wires 31 having a predetermined thickness. Preferably, the plastic mat 31 has a constant diameter and is pressed at a constant pressure And formed into a square shape. The diffusion mat (30) has a void (32) formed between the wires (31) and has a constant porosity. The diffusion mat 30 has a structure similar to a vegetation mat or a civil engineering mat.

Next, FIG. 3 shows a second embodiment of the diffusion mat integrated infiltration hopper 1 according to the present invention. As shown in the figure, two supports 16 are installed on the lower surface 13 of the body case 10 so as to face each other. The two supports 16 protrude outward from the lower surface 13 of the body case 10. [ Preferably, the two supports 16 are installed to support both sides of the diffusion mat 30. At this time, the diffusion mat (30) can be fixed using a band (19) wound on the outer surface of the body case (10). The support 16 facilitates the installation of the diffusion mat 30 and prevents the diffusion mat 30 from being damaged when storing or transporting the diffusion mat integral infiltration bar 1 and in the course of construction . In addition, the support table 16 protects the diffusion mat 30 from earth pressure even after installation.

Next, Figs. 4 and 5 show a third embodiment of the diffusion mat integrated permeation vessel 1 according to the present invention. As shown in the figure, a plurality of support rods 16 are integrally formed on the outer side surfaces of the side surface 12 and the bottom surface 13 of the body case 10. The support base 16 is installed to protrude outward from the side surface 12 and the bottom surface 13 of the body case 10. [ Preferably, the support base 16 forms receiving grooves 20 for supporting upper, lower, left and right sides of the diffusion mat 30. [ In addition, a plurality of through holes 15 are formed in the support 16.

The diffusion mat 30 and the water permeable sheet 40 are provided on the outer side surfaces of the side surface 12 and the bottom surface 13 of the body case 10. The permeable sheet 40 may be installed on the front surface of the diffusion mat 30 or may be entirely enclosed on the outside of the body casing 10 to which the diffusion mat 30 is attached. At this time, the diffusion mat 30 serves to diffuse the rainwater discharged from the main body 10, and the permeable sheet 40 serves to block the inflow of the soil into the void of the diffusion mat 30 .

4, an inlet pipe 17 is installed at one side of the body case 10, and an outlet pipe 18 is provided at the other side thereof. Accordingly, the rainwater flowing through the inflow pipe (17) is discharged to the outside through the through hole (15), and the rainwater having a certain level or higher is discharged to the outside through the outflow pipe (18). At this time, the inlet pipe (17) and the outflow pipe (18) are formed with the other pipe, and the water permeable sheet (40) is wound on the outer peripheral face. The permeable sheet (40) prevents the inflow of the soil into the inflow pipe (17) and the inflow pipe (18). A lid 19 may be installed on the upper portion of the body case 10. The lid 19 may be hermetically closed or may be open-ended through a grill. In the case of the open lid 19, rainwater can flow into the inner space 11 through the grill.

More specifically, the body case 10 is made of metal, plastic, or concrete. A plurality of through holes (15) are formed in the side surface (12) and the bottom surface (13). On the outer surfaces of the side surface 12 and the bottom surface 13, a support table 16 for supporting the diffusion mat 30 is installed. As shown in FIG. 5, the support base 16 may have an arc shape curved at a predetermined curvature. The support base 16 may be integrally formed with the body case 10 or may be separately manufactured and attached to the body case 10.

As shown in the figure, the diffusion mat 30 of the present embodiment is formed by laminating a plurality of plastic meshes 33. The plastic net 33 is formed by molding a plastic wire 31 having a predetermined diameter into a lattice shape.

Accordingly, the diffusion mat 33 having a predetermined thickness can be manufactured by laminating the plastic net 33 having various sizes and shapes. In particular, the diffusion mat 30 of the present embodiment can control the thickness and the porosity by adjusting the number of the plastic net 33. Further, by providing the plastic net 33 having a small gap toward the outer side, it is possible to maximize the porosity and to prevent the soil or sand from being introduced into the diffusion mat 30.

Next, Fig. 7 shows another embodiment of the diffusion mat according to the present invention. As shown in the drawing, the diffusion mat 30 of the present embodiment is integrally provided with the water permeable sheet 40 on the outer surface of the front surface. The permeable sheet (40) is made of a nonwoven fabric having a small porosity and blocks the inflow of soil into the void of the diffusion mat (30).

The spreading mat 30 and the water permeable sheet 40 are integrally provided on the outer surface of the main body cylinder 10 so that the crushed stone It is not necessary to separately install the water permeable sheet or the water permeable sheet.

As described above, since the crushed stone is not charged in the vicinity of the body case 10, the step of transporting and filling the crushed stone is omitted, and the workability in the field is improved, and the construction cost can be reduced by shortening the construction period. Further, since the diffusion mat (30) is used as the porosity in the present invention, the penetration treatment capacity per unit volume is large. Accordingly, the rainwater discharged from the body case 10 can be rapidly diffused and impregnated into the soil.

Hereinafter, a method of attaching the diffusion mat 30 according to the present invention to the outer surface of the body case 10 will be described. 8 shows a coupling structure of the diffusion mat 30 according to the present invention. The spreading mat 30 of the present invention can be fixed to the side surface 12 and the bottom surface 13 of the body case 10 by using a plurality of fastening bolts 60. [ At this time, the fastening bolts 60 are inserted through the through holes 35 formed in the diffusion mat 30 and the through holes 15 formed in the body case 10.

9 is a perspective view showing an example of a fastening bolt according to the present invention. The fastening bolt 60 includes a bolt 62 having a fixing head 63 integrally formed at one end thereof, a nut 64 coupled to the other end of the bolt 62, And a pivoting head 65 installed to be vertically rotatable and vertically standing.

More specifically, the bolt 62 has a fixing head 63 integrally formed at one end thereof and a helical section 162 having a predetermined length formed at the other end thereof. The threaded portion 162 is formed with a thread groove so that the nut 64 can be screwed.

The pivoting head 65 is inserted into the body cylinder 10 in a state of being horizontally coupled to the upper surface of the bolt 62, and then is pivoted downward by its own weight to be vertically erected to enable bolt fastening. The pivoting head 65 includes a main body 165 formed into a substantially cylindrical shape. The body 165 is made of a metal and has a size and shape that can pass through the through hole 15 formed in the body case 10 while being horizontally coupled to the bolt 62. Further, the pivoting head 65 is structured to be able to pivot downward by gravity in a state of being fully inserted into the inside of the body case 10. [

For this purpose, an upper opening portion 166 and a lower opening portion 167 are formed on the upper surface and the lower surface of the main body 165 so that the bolt 62 can freely rotate. At this time, the lower opening portion 167 is formed over the entire longitudinal direction of the main body 165, and the upper opening portion 166 is formed only at the front portion of the upper surface of the main body 165. A connecting portion 168 for supporting the upper surface of the bolt 62 is formed on the rear surface of the upper surface of the main body 165.

Therefore, when the pivoting head 65 is installed horizontally on the upper surface of the bolt 62, the lower surface of the connecting portion 168 contacts the upper surface of the bolt 62. When the pivoting head 65 is rotated downward, the bolt 62 communicates with the upper opening portion 166 and the lower opening portion 167. When the pivoting head 65 is vertically installed on the bolt 62, the inner end of the connecting portion 168 is in contact with the upper surface of the bolt 62.

The outer diameter of the pivoting head 65 is sized to pass through the through hole 15 formed in the body cylinder 10 while being horizontally coupled to the upper surface of the bolt 62. The inner diameter (inner diameter) of the pivoting head 65 is such that the fixed head 63 can not pass through.

10 shows a method of fixing the diffusion mat 30 using the fastening bolt 50 according to the present invention. First, a penetration hole 35 through which the bolt 62 of the fastening bolt 60 can be inserted is formed in the diffusion mat 30. The through hole 35 can be formed using an electric drill or the like.

10 (a), the diffusion mat 30 is installed on one side of the body case 10 of the present invention. The through hole 35 of the diffusion mat 30 is aligned with the through hole 15 formed in the body case 10.

10 (b), the fixing head 63 of the fastening bolt 60 of the present invention and the pivoting head 63 of the present invention are provided with the diffusion mat 30 on the outer surface of the main body cylinder 10, The through hole 35 of the diffusion mat 30 and the through hole 15 of the body case 10 are inserted into the interior of the body case 10. At this time, the pivoting head 65 is coupled horizontally along the longitudinal direction of the fastening bolt 60, and the operator holds the pivoting head 65 with the fingers so that the pivoting head 65 does not rotate downward due to gravity.

10 (c), when the fixed head 63 and the pivoting head 65 are completely inserted into the inner space 11 of the body case 10, the pivoting head 65 is moved to the self weight So that it is vertically erected. Thus, when the pivoting head 65 is vertically erected, the operator pulls the bolt 62 outward so that the fixed head 63 and the pivoting head 65 are brought into close contact with each other.

When the nut 64 coupled to the spiral part 162 of the bolt 62 is rotated, the pivoting head 65 is brought into close contact with the inner surface of the body case 10, The diffusion mat 30 is firmly fixed to the outer surface of the body case 10. At this time, it is preferable to provide a reinforcing plate 69 made of a plastic plate or a metal plate between the nut 64 and the diffusion mat 30. Also, it is preferable that the bolt 62 protruding forward of the diffusion mat 30 is cut and cleaned.

Since the fastening bolts 60 according to the present invention are fully bolted to the outer surface of the body case 10, even when the operator can not approach the inside of the body case 10, Can be easily fixed. In addition, the fastening bolt 60 of the present invention can easily mount a very thick diffusion mat 30 or a plurality of diffusion mat 30 by extending the length of the bolt 62.

11 and 12 show the fourth and fifth embodiments of the diffusion mat integrated infiltration hopper 1 according to the present invention. A diaphragm 25 larger than the diameter of the body case 10 is provided on the side surface 12 and the lower surface 13 of the body case 10 as shown in FIG. A diffusion mat (30) is installed between the diaphragms (25). In this embodiment, the size of the diffusion mat 30 is maximized to increase the diffusion efficiency.

 More specifically, the diaphragm 25 is made of a metal or a plastic material and is fixed to the side surface 12 and the bottom surface 13 of the body case 10. At this time, a plurality of through holes 15 are formed in the partition plate 25. A plurality of diffusion mat (30) are stacked and fixed between the diaphragms (25).

 For example, in Fig. 11, a plurality of diaphragms 25 are provided on the outer surface of a cylindrical main body cylinder 10. As shown in Fig. The diaphragm 25 is formed in the radial direction. A plurality of diffusion mat (30) are stacked between the two diaphragms (25). The diffusion mat 30 is gradually enlarged in size. The plurality of diffusion mats 30 are fixed through the fastening bolts 60 according to the present invention.

Meanwhile, a spacer 50 may be further provided between the diffusion mat 30. As shown in FIG. 13, the spacer 50 has a plurality of cross bars 52 or vertical bars 53 formed inside the frame 51 having a predetermined size and shape. The spacers 50 are installed between the diffusion mat 30 to reinforce the strength of the diffusion mat and to increase the porosity. A plurality of protrusions 54 may be formed on the surface of the spacer 50 to make the connection with the plastic net 30 rigid.

12, a plurality of diaphragms 25 are provided on the outer surface of the rectangular main body 10 and a plurality of diffusion mats 30 are stacked between the diaphragms 25. [ At this time, the plurality of diffusion mats 30 are fixed to the main body cylinder 10 through the fastening bolts 50 according to the present invention. Further, a spacer 50 may be further provided between the diffusion mat 30.

14 shows a method of connecting a plurality of body cylinders 10 and installing a diffusion mat 30 between the diaphragms 25. [ That is, the two body tubes 10 are coupled to each other and the diffusion mat 30 is installed between the two diaphragms 25. Therefore, if the plurality of body cylinders 10 are horizontally connected and the diffusion mat 30 is installed between the diaphragms 25, the infiltration treatment capacity per unit volume becomes large, and a large amount of rainwater can be treated.

Finally, FIG. 15 shows a preferred installation example of the diffusion mat integrated infiltration container 1 according to the present invention. As shown in the drawings, the diffusion mat integrated infiltration barrel 1 of the present invention has a diffusion mat 30 and a water permeable sheet 40 integrally provided on the side surface 12 and the bottom surface 13. Therefore, it is not necessary to fill the crush stone in the vicinity of the main cylinder 10 or to install the permeable sheet.

Accordingly, the diffusion mat integrated infiltration barrel 1 according to the present invention can be precisely installed horizontally by installing the main barrel 10 on the sand layer 7 without installing it on the crushed stone. Accordingly, the present invention improves the workability, saves time, and shortens the construction period, thereby reducing the construction cost. In addition, since the pores of the diffusion mat 30 are larger than the crushed stone, the main cylinder 10 and the diffusion mat 30 can be installed in a space where the infiltration treatment capacity per unit volume is large and the crushed stone is filled, The total required land area can be greatly reduced.

The present invention has been described in detail with reference to the accompanying drawings, but it should be understood that the present invention is not limited by these embodiments.
