Description

  The present invention relates to a drainage basin that collects rainwater and other rainwater and drains it into a sewer through a drain pipe.

  Conventionally, a water collecting basin that collects rainwater and other rainwater that has flowed into the rain gutter and drains it into a sewer through a drain pipe has been buried around the house (see, for example, Patent Document 1). .

  FIG. 3 is an explanatory view showing a cross section of a conventional general water collecting basin. As shown in FIG. 3, a conventional water collecting basin 100 is made of concrete and has a box-shaped casket body 101 having a predetermined depth with an upper portion opened, and a lid for closing the upper portion of the casket body 101. And the body 102. 3 indicates the ground around the house, 105 indicates the concrete covering the surface of the ground 103, and 104 indicates the foundation for embedding the catchment 100. The chestnut stone used as the material is shown.

  In this water catchment 100, a water catching hole 106 is formed in the lid 102, into which a call 113 communicated with a rain gutter (not shown) can be inserted, and it flows into the rain gutter through the water catchment hole 106. The rainwater was configured to flow into the main body 101.

  Further, the water collecting basin 100 is provided with a communication hole 108 communicating with the drainage pipe 107 at a predetermined position on the side wall portion of the main body 101, and drains rainwater from the communication hole 108 to the sewer through the drainage pipe 107. Was configured to do.

  In the water collecting basin 100, the communication hole 108 is formed at a predetermined height from the bottom of the culvert body 101, so that the portion from the bottom of the basin body 101 to the lower end of the communication hole 108 serves as a mud reservoir. The rainwater from which the mud sand is removed in the mud reservoir is drained to the drain pipe 107 side.

  That is, in this catchment 100, when rainwater flows into the main body 101 during rain, up to a certain amount of rainwater is stored in the mud pool, and mud sand 110 contained in the rain water is stored in the mud pool 101. When the rainwater exceeding the predetermined amount flows into the dredged main body 101, the water 109, which is the supernatant accumulated in the mud reservoir, is moved to the drain pipe 107 side. It is drained.

As described above, in the conventional catchment basin 100, by draining the water 109 from which the mud sand 110 has been removed as much as possible from the rainwater to the drain pipe 107, the mud sand 110 accumulates in the drain pipe 107 and the drainage efficiency decreases. I was trying to prevent that.

  Hereinafter, an embodiment of a water collecting tank according to the present invention will be specifically described with reference to the drawings.

  FIG. 1 is an explanatory view showing a cross section of a water catchment according to the present embodiment, and FIG. 2 is an explanatory view showing a modification of the water permeable plate provided in the water catchment according to the present embodiment. Here, as an example of a catchment basin, for a catchment that is buried around a house and collects rainwater and other rainwater that has flowed into the gutter, and drains it into a sewer through a drainpipe. The case where the present invention is applied will be described. However, the present invention is not limited to this, and various drainage basins such as those installed at junctions or junctions of various drainage pipes used in water and sewerage systems, gutters, etc. Can be applied.

  As shown in FIG. 1, a water collecting basin 1 according to this embodiment has an opening 2 at the bottom, a communication hole 5 communicating with a drain pipe 4 at a side wall 3, and a casket body having an open top. 6, a water permeable plate 7 having water permeability for closing the opening 2 formed in the bottom from the inside of the main body 6, and a water permeable sheet having water permeability disposed in contact with the bottom outer surface of the main body 6. 8 and a lid 9 that closes the top of the bag main body 6.

  The main body 6 is made by molding concrete, embedded in a predetermined position on the ground 10 around the house, collects rainwater and other rainwater that has flowed into the rain gutter, and passes through a drain pipe. It is used to drain to sewers. Here, concrete is used as a material for producing the main body 6, but synthetic resin or metal can be used as long as it can prevent rainwater collected in the main body 6 from leaking to the surrounding ground. Any material such as ceramics can be used.

  The opening 2 formed at the bottom of the heel body 6 has a width narrower than the width between both inner walls of the heel body 6 and has a length corresponding to the thickness of the bottom of the heel body 6. ing.

  Further, a stepped portion having the same depth as the thickness of the lid body 9 is formed on the inner periphery of the open portion of the top of the heel body 6, and by fitting the lid body 9 to this stepped portion, The top of the heel body 6 is closed.

  In addition, the communication hole 5 formed in the side wall portion 3 of the heel body 6 has a lower end formed at a position higher than the upper surface of the water permeable plate 7 by a predetermined height. The area between the upper surface of the water and the lower end of the communication hole 5 is made to function as the mud sand storage part 11 in which mud sand contained in the collected water is stored.

  Thus, in the water catchment 1 of this embodiment, the mud sand storage part 11 is provided in the dredger main body 6, and the rainwater collected on the dredger main body 6 using the sedimentation action of the mud sand in the mud sand storage part 11 is provided. Is separated into mud sand and supernatant water, and the supernatant water from which mud sand is removed as much as possible is drained to the drain pipe 4 to prevent the mud sand from accumulating in the drain pipe 4. The drainage is kept good.

  The lid body 9 that closes the upper portion of the bag main body 6 is made of a metal plate whose thickness is equal to the depth of the stepped portion, and a call ring that communicates with a rain gutter (not shown) at a predetermined position. A water collecting hole 13 into which 12 can be inserted is formed, and rain water that has flowed into the rain gutter through the water collecting hole 13 is made to flow into the gutter body 6.

  In particular, the water permeable plate 7 that closes the opening 2 at the bottom of the ridge body 6 is constituted by a plate formed of porous porous concrete having water permeability.

  Therefore, in this catchment 1, the rainwater stored in the mud sand storage part 11 at the time of a small amount of rain or after the rain has gone up passes through the water permeable plate 7 and is drained to the ground side.

  Therefore, the water collecting basin 1 does not always store rainwater in the casket main body 6 and does not become a hotbed for generating pests.

  Moreover, since the water-permeable board 7 is formed with the porous concrete as mentioned above, sufficient water permeability and intensity | strength can be ensured, although it is comparatively low cost.

  Further, the water permeable plate 7 is formed so that the upper surface thereof has a thickness located below the lower end of the communication hole 5 in a state in which the opening 2 is closed. A mud sand storage part 11 is formed between the upper surface of the plate 7 and the lower end of the communication hole 5.

  Further, the water permeable sheet 8 disposed in contact with the bottom outer surface of the ridge body 6 is formed of a known sheet having a lower water permeability than the permeable plate 7. A large amount of rainwater is prevented from being drained to the side in a short time to suppress softening of the ground, and the catchment basin 1 is prevented from being buried unnecessarily in the ground.

  Moreover, in this water collecting tub 1, the water permeable sheet 7 is closed by closing the opening 2 with the water permeable sheet 8 from the outside of the tub main body 6 and with the water permeable plate 7 from the inside of the main body 6. A gap (region of the opening 2 shown in FIG. 1) is formed between the permeable sheet 8 and the water permeable sheet 8.

  For this reason, in this catchment basin 1, when there is a small amount of rainwater stored in the casket body 6, the rainwater permeates the water permeable plate 7 and is discharged into the gap. Since it is not immersed in rain water and there is little possibility of moss etc. arising in the inside of the water-permeable board 7, the water permeability of the water-permeable board 7 can be kept as long and favorable as possible.

  Here, the installation method of the water catchment 1 comprised in this way is demonstrated. When installing the water collecting rod 1, first, a hole wider than the bottom area of the rod main body 6 and deeper than the depth of the rod main body 6 is excavated at a predetermined position on the ground 10 around the house.

  Next, crushed stone is laid on the bottom of the hole to form a base layer 14 for embedding the water collecting trough 1 with a predetermined thickness.

  Next, the water-permeable sheet 8 is laid so as to cover the surface of the foundation layer 14, and the bottom surface of the heel body 6 is brought into contact with the surface of the water-permeable sheet 8. The drainage pipe 4 is inserted into the communication hole 5 formed in the portion 3 to position the rod body 6.

  Next, by placing the water permeable plate 7 on the bottom of the heel body 6, the opening 2 is closed from the inside of the heel body 6, and then the gap between the heel body 6 and the ground 10 is filled with soil. Concrete 15 is placed on the surface of the ground 10 around the body 6.

  Next, the lid 9 is fitted into a step formed on the top of the heel body 6 to close the open portion of the top of the heel body 6, and finally, into the water collecting hole 13 of the lid 9. Inserting the call 12 that communicates with the gutter completes the installation of the catch 1.

  In the drainage basin 1 thus installed, the rainwater that has flowed into the raindrop during rainfall flows into the interior of the casket body 6 through the callout 12 inserted into the water collection hole 13.

  Rainwater that has flowed into the main body 6 is stored in the mud storage unit 11 until the water reaches the lower end of the communication hole 5, and is separated into mud sand and supernatant water by the sedimentation action of the mud sand. Is done.

  Thereafter, when the water in the dredge body 6 increases and exceeds the lower end of the communication hole 5, the supernatant water in the mud sand reservoir 11 flows into the drain pipe 4 through the communication hole 5 and communicates with the drain pipe 4. It is discharged into the sewers.

  After that, when the rain stops, the rainwater stored in the mud sand storage part 11 (including the water containing the supernatant water and the mud sand) passes through the water permeable plate 7, and the water permeable plate 7 and the water permeable sheet 8 It flows into the gap formed between the permeable sheet 8 and drains gradually from the water-permeable sheet 8 through the foundation layer 14 to the ground side, and finally the inside of the main body 6 is dried.

  As described above, in the catchment basin 1 according to the present embodiment, the rainwater stored in the mud sand storage unit 11 is drained to the ground side after raining, so that the catchment basin 1 is used as a hotbed where pests are generated. It is comprised so that it may become.

  Moreover, in the said embodiment, although the water permeable plate 7 was comprised by the plate body formed with the porous concrete, the water permeable plate in use is provided by providing a holding part in the water permeable plate 7 as a modification of the water permeable plate 7. When the water permeability of 7 is deteriorated, the water permeable plate 7 can be replaced with a new one by gripping the grip portion.

  That is, as shown in FIG. 2, the water permeable plate 7a according to this modified example forms a semicircular arc-shaped concave portion in cross section so that a finger can be locked at both end edges, and the width of the upper surface of the water permeable plate 7a is increased. The holding part 7b is formed by forming it narrower than the width of the bottom surface.

  As described above, by providing the grip portion 7b on the water permeable plate 7a, moss or the like is generated inside the water permeable plate 7a due to repeated rainfall, moisture inside the bag main body 6 or the like, and the water permeable plate 7a is clogged. Even when the water permeability is deteriorated, the old water permeable plate 7a can be easily replaced with a new water permeable plate 7a.
