Description

  The present invention mainly stores rainwater collected through rain gutters on the roof of a detached house and can effectively utilize rainwater that can be infiltrated into the ground while adjusting rainwater exceeding the storage capacity. The present invention relates to a detached housing complex equipped with a regulated storage and penetration device.

  Recent residential land development is often created not only on flat land but also in hilly and mountainous areas. In such a site, the surrounding land environment such as residential land has been transformed into roads and parking lots, and the ground surface is covered with asphalt and concrete. When heavy rain falls in such an environment, the rainwater collected through the gutters on the roof of the house flows into the drainage ditch, and the rainwater that falls on the road or parking lot flows from the asphalt or concrete surface to the drainage ditch. Furthermore, it flows from a small river to a large river.

  In conventional construction sites, there are many surface parts that are not covered with asphalt or concrete, and the residential land is not very dense, so it was easy for rainwater to penetrate into the ground, but as the land development progressed, the surface part When residential land becomes denser, rainwater from heavy rains will flow in large amounts in gutters and drains. And if the rainfall per unit time increases rapidly, it will cause flooding in the worst case.

For this reason, it is obliged to install an adjustment pond and rainwater storage device for temporarily storing rainwater in the site, and an adjustment pond and rainwater storage device according to the area of the site are installed at one corner of the site. Yes. In recent years, in order to use rainwater effectively, such as watering a garden, flush toilet water, or emergency water, a miniaturized rainwater storage device may be installed in the garden of each detached house.

  However, the adjustment pond and the rainwater storage device in the above-mentioned creation site are required to be large-scale in order to correspond to a plurality of detached houses constructed in the creation site, and a vast area is required. For this reason, there was a problem that the land where the adjustment pond and the rainwater storage device were installed could not be used effectively. Moreover, since the adjustment pond is usually kept in an empty state, there is a problem that the landscape becomes worse. In addition, there is a method in which the land where the rainwater storage device is installed is converted into a green park or used as a parking lot. However, there is a problem in that it is generally installed at the end of the developed land and is not convenient.

  In addition, in the method of installing a miniaturized rainwater storage device in the garden of each detached house, there is no need for an adjustment pond that requires a large area and a land for installing the rainwater storage device, and more houses can be built accordingly. Therefore, it was possible to effectively use the site, but it had only a function of storing rainwater and could not infiltrate rainwater underground. As a result, the underground environment deteriorated, and there were problems such as the rise of surface temperature and the heat island due to the depletion of water resources and the transpiration effect not functioning in the summer.

  The present invention has been made to solve the above-described problems. In a detached house constructed on a construction site, rainwater collected through a gutter on the roof of the detached house is detached. A detached housing complex with a rainwater adjustment storage and penetration device that can be stored and used effectively for each house and can improve the underground environment by adjusting the rainwater exceeding the storage capacity and allowing it to penetrate into the ground. The purpose is to provide.

In addition, an inflow pipe for allowing rainwater collected through the rain gutter on the roof of a detached house to flow into the rainwater storage part is penetrated on the upper side of the rainwater infiltration part, and the rainwater infiltration part is fixed on the lower side of the inflow pipe. An outflow pipe is provided to allow rainwater that has flowed in beyond the capacity to flow out to the external gutter. Further, a water supply pipe for supplying rainwater stored in the rainwater storage section to the outside is provided on the upper surface of the rainwater adjustment storage permeation apparatus, and the water supply pipe is connected to a water supply pump installed in the garden.

  If the detached housing complex where the rainwater adjustment storage and permeation device of the present invention is deployed is developed in every creation land, the rainwater collected through the rain gutter of the roof of each detached housing constituting the detached housing complex is separated for each detached house. Since it can be stored, there is an effect that it can be effectively used for garden watering, flush toilet water or emergency water. In addition, since rainwater exceeding the storage capacity in the rainwater adjustment storage and infiltration device can be adjusted and infiltrated into the ground, the underground environment can be improved in accordance with natural circulation, and urban flooding and heat islanding can be improved. It has the effect of helping to prevent it. In addition, since there is no need for a large-scale adjustment pond or rainwater storage device, there is a tremendous effect that the land can be effectively used in the constructed land.

  The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is an installation system diagram of a rainwater adjustment storage and permeation device in a detached house constituting a detached housing estate where the rainwater adjustment storage and permeation device of the present invention is provided.

The rainwater adjustment storage and permeation device 4 is embedded as a rainwater permeation portion 4b for allowing the rainwater 14 that has flowed in through the ground to penetrate into the ground through the permeation hole 15 while adjusting. The capacity of the rainwater storage part 4a and the capacity of the rainwater infiltration part 4b of the rainwater adjustment storage and infiltration device 4 are calculated based on the number of eaves of each detached house 1 constituting the detached housing estate, the area of the site, and the occupied area such as roads. The capacity rainwater adjustment storage permeation device 4 is determined.

  In addition, an inflow pipe 6 for allowing rainwater 14 collected through the rain gutter 2 on the roof of the detached house 1 to flow into the rainwater storage part 4a is provided on the upper side of the rainwater infiltration part 4b. On the side, an outflow pipe 7 is provided through which the rainwater 14 that has flowed in beyond the fixed capacity of the rainwater infiltration portion 4b flows into the external side groove 8. Furthermore, a water supply pipe 9 for supplying rainwater 14 stored in the rainwater storage part 4 a to the outside is provided on the upper surface of the rainwater adjustment storage permeation apparatus 4, and the water supply pipe 9 and a water supply pump 10 installed in the garden 3 are provided. Connecting. Moreover, gravel 5 for enhancing the permeation effect is spread around the rainwater adjusting and storing permeation apparatus 4. In addition, the positional relationship of the said inflow pipe 6, the outflow pipe 7, and the water supply pipe 9 is not limited to the position shown in figure, It arrange | positions according to the building state of the actual detached house 1. FIG.

  Embodiments of the present invention will be described with reference to the drawings. First, as shown in FIG. 1, in the garden 3 of each detached house 1 constituting the detached housing estate, the lower tank is a rainwater storage part 4a for storing rainwater 14, and the upper tank is stored in the rainwater storage part 4a. A rainwater adjustment storage and infiltration device 4 is embedded as a rainwater infiltration portion 4b for infiltrating into the ground through the infiltration hole 15 while adjusting the rainwater 14 that has flowed in beyond the capacity. Further, gravel 5 is spread around the rainwater adjusting and storing permeation apparatus 4 to prevent clogging of the permeation holes 15 perforated in the rainwater permeation part 4b and to enhance the permeation effect. In addition, if the permeation hole 15 is drilled in the upper surface of the rainwater infiltration part 4b and the gravel 5 is spread, the rainwater 14 that has fallen on the garden 3 is adjusted and stored in the rainwater through the infiltration hole 15 on the upper surface of the rainwater infiltration part 4b. The permeation device 4 can be permeated and stored.

  FIG. 2 is a cross-sectional view of the rainwater adjustment storage and infiltration device showing a state in which rainwater is stored. The rainwater 14 collected through the rain gutter 2 on the roof of the detached house 1 is the rainwater infiltration of the rainwater adjustment storage and infiltration device 4. It flows in the inflow pipe 6 penetrating on the upper side of the part 4b and is discharged to the rainwater storage part 4a. The rainwater 14 can be stored without penetrating into the ground up to the upper end portion of the rainwater storage section 4a of the rainwater adjustment storage permeation apparatus 4.

  Further, the rainwater 14 stored in the rainwater storage section 4a is supplied to the outside on the upper surface of the rainwater adjustment storage and infiltration device 4 for effective use, for example, watering the garden 3, water for the flush toilet 12, water for emergency use, etc. A water supply pipe 9 is penetrated and connected to a water supply pump 10 installed in the garden 3.

It flows into the side groove 8 of the road 23. When the asphalt or the side ditch 8 of the road 23 has the permeability of the rainwater 14 and the adjustment pond or the rainwater storage device becomes unnecessary outside, the rainwater 14 flows out from the side ditch 8 to the river 24 as it is.

  However, when the asphalt or the side ditch 8 of the road 23 does not have the permeability of the rainwater 14 and the adjustment pond or the rainwater storage device is required outside, a relatively small adjustment pond or rainwater is provided at the end of the side ditch 8. A storage device 20 is installed. In this case, the rainwater 14 that flows out from the rainwater adjustment storage and permeation device 4 installed in each detached house 1 and the rainwater 14 that falls on the road 23 in the detached housing estate 18 and the rainwater 14 that flows into the adjustment pond or the rainwater storage device 20 are caused to flow. For this purpose, an inflow pipe 21 is provided, and an outflow pipe 22 is provided through which the rainwater 14 that has flowed in beyond the storage capacity flows out to the external river 24. The storage capacity of the adjustment pond or the rainwater storage device 20 does not correspond to the site area of the entire detached housing estate 18 but is installed in the rainwater 14 that has fallen on the road 23 in the detached housing estate 18 and each detached house 1. Since it corresponds to the rainwater 14 that has flowed out of the rainwater adjusting and storing permeation apparatus 4, it becomes relatively small. The rainwater 14 flowing out from the side groove 8 is stored in the rainwater adjusting and storing permeation device 4 from the inflow pipe 21 as shown by an arrow b, and the rainwater 14 flowing in exceeding the storage capacity is shown in the outflow pipe as shown by an arrow c. 22 flows out into the river 24 outside.
