It is.

  An automatic groundwater inflow apparatus 19 according to an embodiment of the present invention is a box-shaped concrete structure (PC; Precasting Concreate) 21 joined to a reinforced concrete base 1 of a permeation / storage tank to form an internal space 20, crushed aggregate (FIG. And a perforated tubular underground water inflow passage (underdrain) 22 connected to the inner space 20 of the box-shaped concrete structure 21.

  In general, a culvert is attached to the bottom of most of the basements, but the automatic groundwater inflow apparatus according to an embodiment of the present invention does not forcibly drain the culvert water, and the outflow groundwater and the infiltration / reservoir storage It was developed so that the outflow groundwater flowed into the inside of the infiltration tank by the difference in water head, and most of the fine sediment enters the inside of the infiltration tank by the water flow generated in the inflow process of the outflow groundwater Also, contamination and fines can pack the inflow device and cause failure.

Therefore, by joining the box-shaped concrete structure 21 to the culvert (ground water inflow passage) 22, it is possible to prevent foreign matter from entering the inside as much as possible, and between the box-shaped concrete structure 21 and the reinforced concrete base 1 of the infiltration reservoir. By attaching the water blocking plate 24 also to the joint portion, foreign matter inflow or leakage of the joint portion is prevented.

In addition, the groundwater automatic inlet valve housing 23 is designed.

  The automatic groundwater inflow valve 12 has a pressure switch plate 26 opened and closed by a set pressure, and the pressure switch plate 26 has a structure for backflow prevention, so the pumping pressure of the outflowing groundwater exceeds the set pressure of the pressure switch plate 26 For example, the pressure switching plate 26 is automatically opened, and the outflowing groundwater only penetrates one way through the inside of the storage tank and flows in, and the storage water of the permeation and storage tank is the pressure switching plate 26.

  At this time, prior to placing the box-shaped concrete structure 21, the water blocking plate 24 is attached in advance, and the reinforced concrete base 1 of the infiltration / storage tank is placed thereon.

  In addition, prior to placing the reinforced concrete base 1 of the infiltration and storage tank, fix the underground water automatic inlet valve housing 23 to the bottom reinforcing bar etc. and install the concrete densely with a vibrator so that the water blocking plate 32 adheres well to the concrete. Do. Thereafter, the level is adjusted so that the fixed plate 31 is positioned on the same line as the concrete finished surface, and construction is carried out, and the concrete is kept with vinyl or the like so that foreign matter such as concrete does not enter the apparatus.

Thus, the automatic water inflow apparatus 19 according to one embodiment of the present invention is installed at the bottom of the lower end of the infiltration / storage tank, and for easy maintenance, it is a work passage for maintenance that also serves as a vertical manhole. It is installed at the lower part of 10 and 11.

  According to FIG. 8, the infiltration and storage tank for water circulation according to one embodiment of the present invention is connected to the inflow manhole 8 with rainwater infiltration facilities such as the tree filter box 38, the infiltration tube 39, and the infiltration cylinder 40 in a continuous channel. Rainwater is permeated and stored in the storage tank through the continuous flow channel when it rains.

  In addition, the seepage and storage tank for water circulation according to one embodiment of the present invention reduces the lifting pressure of the outflow groundwater due to the rise of the groundwater level when raining, and automatically causes the outflow groundwater to flow into the inside of the penetration and storage tank. The system has an automatic groundwater inflow device 19 which allows groundwater to be stored in the infiltration reservoir.
