The present invention relates to an underground infiltration apparatus for overflow water of rainwater storage and use apparatus using a prefabricated perforated block wrapped with a permeable fabric. More specifically, the present invention relates to an underground infiltration apparatus of overflow water to prevent rainwater from flowing out to sewers or streams at once, and to utilize rainwater to replenish groundwater levels as a water resource in terms of disaster prevention and water circulation.

Weather extremes around the world are making summer floods and winter and spring droughts more serious. In particular, when it rains, there is a high probability of local rainfall, causing concern about flooding in cities. If it rains more than the design capacity of existing sewer pipes, the sewer pipes may be flooded and damaged. In order to prevent this, it is necessary to trap some of the maximum outflow water to delay the outflow time or to penetrate underground so that it does not flow into the sewer pipe.

In addition, the groundwater level is gradually lowered due to the indiscriminate use of groundwater, resulting in problems in water circulation. Therefore, it would be desirable to provide a method for infiltrating rainwater underground.

In the present invention, when installing rainwater utilization facilities in apartments, such as apartments, it provides a technique that is used to prevent flooding of sewerage in advance by replenishing the overflowing rainwater into the basement rather than outflow into the sewerage, and to replenish the groundwater level.

Until now, rainwater utilization technology has been limited to only water-saving techniques for storing and using rainwater, focusing only on the use of rainwater. Such technology is described in Korean Utility Model Registration No. 2002-0025774 and Korean Patent Application No. 2002-0051337. However, when the rainwater reservoir is full and overflowed, there is no technique for maintaining the water circulation to replenish the groundwater or the technique of water supply to flow into the sewer and prevent the sewage from flooding. The present invention is to provide a penetrating device having a function of preventing the inundation of the sewerage and replenishing the groundwater by penetrating the underground before the rainwater overflowed after storage to the sewer.

Existing techniques have the following constraints in terms of dimensions and water circulation and need to be solved.

(1) Rainwater storage and use If the device is full and if it rains again, the device will not help with dimensions. At this time, the overflowed rainwater flows into the sewage pipe as it is, so that the amount of discharged sewage may increase, causing flooding.

(2) When the height of the sewage pipes discharged is high depending on the site conditions, there may be cases where drainage is not possible due to the natural flowing flow,

(3) does not have the effect of groundwater filling,

(4) Rainwater mixed with the initial rainwater or the filtered wastewater flowing out from the rainwater use device will be penetrated into the basement.

(5) When infiltrating, it needs the ability to store all at once and to flow slowly according to the soil's infiltration capacity.

In order to solve this problem, in the present invention, in addition to rainwater storage and utilization facilities, the overflowed rainwater is not sent to the sewage system, but it penetrates into the soil, thereby lowering the risk of inundation of the sewerage downstream, and replenishing groundwater to smoothly circulate water. In the underground penetration device of overflow water of rainwater storage and utilization device,

A cylindrical manhole located between the rainwater storage and utilization device and the porous permeation block, the height of the upper portion of which is equal to the height of the ground surface, made of plastic or concrete, and provided with a manhole cover;

An inlet pipe and an outlet pipe connected to the cylindrical manhole, and the inlet pipe is configured to enter the surplus rainwater flowing out of the rainwater storage and use device through the filter using a screen through the inlet pipe and into the infiltration block through the outflow pipe. And outlet pipe;

Manufactured from plastic or steel net, it is inserted into the c-shaped gutter which is installed on the wall near the outlet pipe of the cylindrical manhole and attached to the wall so that it can be moved up and down along the c-shaped gutter. A filter using a screen which is moved backwards from the entrance and is separated from the trough;

A bottom container provided at an inner bottom of the cylindrical manhole in a size substantially the same as the diameter of the manhole, provided with a handle for lifting up, and made of plastic or iron; And

Rainwater, characterized in that it is made of plastic, such as polyethylene, and has a porosity (volume of voids / total volume) of 95% or more, and includes a porous granular penetrating block that can be assembled and used in a horizontal, vertical or height direction. Provides underground infiltration of overflows of storage and use devices.

The present invention will be described in more detail with reference to the accompanying drawings.

1 shows a porous granular penetrating block 30 of the present invention. The penetration block 30 has a size of 30-40 cm in width, 90-120 cm in height and 30-40 cm in height. The total volume is 0.1-0.3 m ³ . The penetration block 30 is made of a plastic-based material such as polyethylene, and has a porosity (volume of voids / total volume) of 95% or more, and is structurally safe even when a vehicle or a person is on it.

2 shows a form in which the penetration block 30 is assembled. Depending on the amount of rain water to be penetrated, the porous unit penetrating block 30 may be connected in a horizontal, vertical or height direction to form a required volume. In order to connect in the horizontal or vertical direction, two or three plastic clips 31 are inserted into each side of the penetration block 30 to be assembled. In addition, holes in the shape corresponding to the clip 31 are formed in the upper side of the penetration block 30 to accommodate the plastic clip 31. In assembly, the U-shaped plastic clip 31 is pressed from above to fit in the hole. At this time, the plastic clip 31 is inserted to snap into the hole. In addition, the lower end of the plastic clip 31 is processed at the end so as not to fall out after being inserted into the hole. 3 shows the assembly of the penetration block 30 in the height direction. In order to connect in the height direction, four plastic rods 32 (length 10 cm, diameter 2 cm) protruding from the top of the penetration block 30 are provided. In addition, the upper and lower portions of the penetration block 30 is provided with holes 35 at positions corresponding to the plastic rods 32, and the plastic rods 32 and the holes 35 are connected to each other to penetrate the block 30. ) Is fixed up and down.

4 shows a form in which the assembled porous penetrating block 30 is wrapped with a permeable fabric. As described above, one or more assembled porous permeation blocks 30 are wrapped around the permeable fabric 36 to be used for rainwater penetration. The process first excavates and excavates the position where the rainwater is to penetrate, lays the permeable fabric 36 on it, and places the porous permeable block 30 in the center of the permeable fabric 36. The permeable fabric 36 then covers the bottom and side surfaces of the porous permeable block 30 and again covers the top surface, as it builds up the crepe. At this time, as shown in the upper surface of the porous penetrating block 30, both ends of the permeable fabric 36 are bonded to overlap by about 50cm. In operation, the rainwater flowing into the structure slowly penetrates through the permeable fabric 36 and penetrates underground, while particles of external soil can be prevented from entering and accumulating in the infiltration block 30. In addition, after the installation of the porous penetrating block 30, the soil or grass is embedded or covered in the excavated portion.

With reference to Figure 5 will be described in the groundwater penetration device of the overflow water of the rainwater storage and use apparatus using a prefabricated perforated block wrapped with the whole permeable fabric material according to the present invention. The penetrating device of the present invention utilizes the structure of the porous penetrating block 30 described above.

In the penetration device of the present invention, the cylindrical manhole 11 is located between the rainwater storage and utilization device 12 and the porous penetration block 30. The cylindrical manhole 11 acts to prevent debris or foreign matter from passing through as it enters the penetration block 30 to block the penetration block 30. Its size is usually 40-60cm in diameter and the height is calculated as h1 + h2 + h3. h1 is 50 cm, h2 is the diameter of the inlet pipe 15 and h3 is determined according to the height of the surrounding ground. The height of the upper portion of the cylindrical manhole 11 is the same as the height of the ground surface. The material of the cylindrical manhole 11 may be plastic or concrete. The cylindrical manhole 11 is provided with a manhole cover 14 for maintenance and management.

The inlet pipe 15 and the outlet pipe 16 are connected to the cylindrical manhole 11. Surplus rainwater flowing out of the rainwater storage and use apparatus 12 through the inlet pipe 15 enters the infiltration block 30 through the outlet pipe 16 through the filter 17 using the screen. The diameter of the inlet tube 15 and the outlet tube 16 is in the range of 100-200 mm, and the height from the bottom of the cylindrical manhole 11 to the bottom of the tubes 15 and 16 is the same. The outlet pipe 16 is connected to the top of the infiltration block 30 downstream of the flow direction of the rainwater.

The rainwater flowing out of the rainwater storage and use device 12 may be mixed with some foreign matter, so that a filter 17 using a screen is required. The filter 17 is conical and has a height of about 20 cm, a lower diameter of about 15 cm, and an upper diameter of about 5 cm. The filter 17 is made of a plastic or iron mesh and the joint is about 0.1 mm apart. The filter 17 is inserted into the U-shaped gutter which is installed on the wall near the outlet pipe 16 of the cylindrical manhole 11 and attached to the wall. In addition, the filter 17 may be moved up and down along the U-shaped gutter, and during cleaning, the filter 17 is moved in the opposite direction as the entry along the U-shaped gutter, is separated from the gutter, and is pulled out and cleaned over the cylindrical manhole 11. After attaching again.

The inner bottom of the cylindrical manhole 11 is provided with a bottom container 18 of approximately the same size as the diameter of the manhole. The bottom container 18 is provided with a handle to lift upwards and is made of plastic or iron. When debris accumulates on the bottom of the cylindrical manhole 11, the bottom container 18 is lifted by using a handle to remove the debris and to be installed again.

As described above, the permeable fabric 36 surrounding the porous penetrating block 30 serves to prevent the passage of debris or particles between the penetrating blocks. When the filter 17 using the screen is not installed and the residue enters, the residue blocks the pores of the permeable fabric 36 to reduce the effect of penetration. In addition, when particles of soil enter the permeable block 30 through the permeable fabric 36, the volume of the permeable block 30 is reduced while simultaneously reducing the permeability effect of the permeable fabric 36.

As described above, according to the present invention, in addition to the purpose of the existing rainwater storage and utilization technology, the function of the dimensions that can prevent the overflowing rainwater flows into the sewer pipes and causes flooding when it rains a lot, Overflowing rainwater can slowly flow into the basement to increase the level of groundwater and provide a healthy water cycle.

In addition, by installing a simple screen filter in the cylindrical manhole it is possible to prevent the debris from reducing the penetration effect by entering the penetration block to block the voids.

In addition, by supplementing the functions of the existing rainwater storage and use device can provide the effect of preventing the flood and normal water circulation of the groundwater.

In the above, certain preferred embodiments of the present invention have been illustrated and described. However, the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. will be.
