Description

Apparatus having perforated pipes for increasing water storage capacity in river basin}

The present invention relates to an apparatus for increasing the amount of storage of the river basin soil layer in order to prevent flooding, dryness and pollution of rivers flowing through urban areas packed with impermeable paving materials such as asphalt or concrete. The present invention relates to a basin soil low-water increasing device having a leaking pipe that leads to rainwater flowing into the watershed soil layer, which is blocked by the packing material, and flows into the watershed.

As urbanization progresses, the paving rate of roads and other grounds increases. Increasing the area of impervious land surfaces such as asphalt and concrete paving roads reduces the amount of water in the ground, causing flooding and dryness of the surrounding streams, and at the same time causing river water pollution and ecosystem destruction.

As the asphalt or concrete mainly used as road paving material does not pass water, when the paving material is paved on the soil, the soil does not breathe and the underground soil layer gradually changes afterwards.

In addition, when there is a river around the area where the impervious ground is formed widely, rainwater does not penetrate into the soil during rainfall and gathers into the river at once, which may cause flooding of the river. Due to the low or no amount of water in the water, the lack of water in rivers may occur. Insufficient water yields lead to a significant weakening of the river's natural cleansing power, as well as severe water deterioration.

The best way to solve the problems caused by the reduction of the soil water storage is to enlarge the permeable surface to form a grassland or forest over a large area so that water can seep directly into the soil. However, it is virtually impossible to secure such a green space in a city where the parking space is tight.

As a result, in some countries, a small hole through which water can pass through the asphalt or concrete layer can be used for permeation. However, the amount of permeation is small and the safety of the ground cannot be guaranteed.

The present invention has been created to solve the above problems, by introducing the rainwater that flows into the ground due to the impermeable pavement layer into the ground to supply to the soil layer so that the soil can receive abundant water as a whole is advantageous for water resource management Even in cities with high land-covering rates, underground soils are not dry and rich in groundwater, and especially when there are rivers nearby, they can prevent flooding or dry- ning of rivers, as well as increase the minimum quantity of rivers It is an object of the present invention to provide a basin soil low water increasing apparatus having a leaky pipe to improve and clean the environment.

1 is a view schematically illustrating a configuration of a watershed soil low water increasing apparatus having a leaky pipe according to an embodiment of the present invention.

As shown, the basin soil low water increasing apparatus of the present embodiment, four leakage pipes 20 embedded in the soil layer 12, and one end of the leakage pipe 20 is inserted into the pipe connection ( 32, the pit chamber 16 is installed on the leakage pipe 20 and connected to each other, and the screening chamber 40 and the grit chamber 48. In addition, the pipe connector 32 and the grit chamber 48 is in communication with each other via a connecting pipe (18).

The pit chamber 16 is a rectangular space provided so that rain water flowing on the paving layer 10 flows into the inside thereof, and the grill 14 is covered on the upper portion thereof. The grill 14 allows rainwater to flow into the pit chamber 16, but filters out various wastes mixed in the rainwater into the pit chamber 16. Of course, the grill 14 should have rigidity that does not deform even when external force is applied.

The screening chamber 40 is a rectangular space formed at the side of the pit chamber 16, and two screens 42 are inclined therein. The screening chamber 40 and the pit chamber 16 are connected through a connection hole 44. Therefore, when the rainwater collected in the pit chamber 16 reaches a level corresponding to the height of the connection hole 44, the rainwater moves from the pit chamber 16 toward the screening chamber 40.

In addition, the two screens 42 installed inside the screening chamber 40 are filters for filtering foreign matter in the rainwater moving from the pit chamber 16 to the grit chamber 48. The screen 42 is a mesh-shaped member having a rectangular rim which is in contact with the inner wall surface of the screening chamber 40. The number of applications of the screen 42 may vary depending on the embodiment, of course.

The cover 50 is covered with an upper portion of the screening chamber 40. The cover 50 normally closes the screening chamber 40 and is opened to clean the screen 42 or inside the screening chamber 40, if necessary.

The grit chamber 48 is provided at the side of the screening chamber 40. The grit chamber 48 is well known in the field of water treatment, and slowly passes water into the chamber and allows sand or soil in the water to settle to the bottom while the water passes.

The screening chamber 40 and the grit chamber 48 are connected to each other through a connection hole 45. Therefore, the rain water passing through the screening chamber 40 moves over the connection hole 45 into the grit chamber 48 and gradually flows into the grit chamber 48 to allow the sand or soil therein to settle to the bottom.

The cover 51 is also covered on the top of the grit chamber 48. The cover 51 has the same function as the cover 50 covering the screening chamber 40.

The pit chamber 16, the screening chamber 40, and the grit chamber 48 may be made of concrete in terms of cost, and may be made of synthetic resin or steel stainless in some cases.

The connecting pipe 18 connecting the grit chamber 48 and the pipe connector 32 may be made of a concrete pipe and may be made of a synthetic resin or steel pipe according to an embodiment.

In addition, the upper end of the connecting pipe 18 is connected to the wall surface of the grit chamber 48, but also connected to the upper side of the wall to pass the rain water far from the sand (s) of the rain water flowing through the inside of the grit chamber 48. do.

The pipe connector 32 communicating with the lower end of the connecting pipe 18 is opened to the leaking pipe 20 side as shown in FIG. 4 to receive one end of each leaking pipe 20 therein. The pipe connector 32 guides the water supplied through the connecting pipe 18 to move to the leaking pipe 20 once without leaking to another place.

If the connecting pipe 18 can be directly connected to each leak pipe 20, the pipe connector 32 is of course not necessary.

On the other hand, the leak pipe 20 is a pipe having both ends open and a plurality of through-holes 22 are formed on the main surface, it can be made of steel, stainless steel, concrete or synthetic resin.

In the present embodiment, the four leak pipes 20 are applied and stacked two by one up and down, but the arrangement method and the number of pipes are varied depending on the working conditions.

In the leak pipe 20, the upstream side of the leak pipe 20 is positioned at a position higher than the downstream side. That is, the leakage pipe 20 is inclined so that the rainwater supplied into the leakage pipe 20 flows in the direction of arrow a through the pipe connector 32. Water moving in the direction of arrow a is drained into the soil layer 12 through the hole 22 during movement.

In addition, according to the embodiment, each hole 22 of the leak pipe 20 may be blocked by a screen net (not shown) to prevent soil layer soil from flowing into the leak pipe 20.

Eventually, in the basin soil low water increasing apparatus having a leak pipe configured as described above, the rainwater flowing on the pavement layer 10 without seeping into the ground once flows into the pit chamber 16 and the screening chamber 40. And after passing through the grit chamber 48 is purified to move along the path provided by the connecting pipe 18 and the leaking pipe 20 to seep into the soil layer (12).

Rainwater penetrating into the soil layer 12 as described above is gradually purified in the soil layer and moves to the surrounding stream or stays underground.
