1 to 5, the water collecting well according to the embodiment of the present invention communicates with the main body 10 and the main body 10 formed by constructing an inner wall in a groove portion formed in the ground to collect rainwater. A drain pipe 30 connected to the surrounding drainage channel, a cover part 70 installed on the main body 10 to support the weight of a pedestrian or a vehicle, and filtering out foreign substances contained in rainwater, a drain pipe 30 and a cover part 70. It includes a sieve net (50) installed between and filtering the foreign matter contained in the rainwater, and the sedimentation tank (16) is formed to partition the inside of the main body 10 and the passage hole (16a) is installed.

When rainwater flows into the basement of a road or building, rainwater flows into the main body 10 through the cover part 70, and the rainwater flowing into the main body 10 passes through the strainer 50 and flows along the drain pipe 30. Or discharged to a nearby drain.

At this time, the foreign matter contained in the rainwater flowing into the sedimentation tank 16 is filtered by the cover portion 70, the foreign matter contained in the rainwater introduced into the main body 10 is filtered by the strainer 50, the strainer ( The foreign matter filtered by 50) accumulates on the bottom surface of the immersion tank 16.

Foreign matter that has passed up to the sieve (50) is accumulated on the bottom surface of the main body 10, the rainwater moved to the bottom surface of the main body 10 along the water pipe 30 connected to the side of the main body 10 or the river Is discharged to the drainage of.

The strainer 50 is installed in the through hole part 16a and the inner strainer net 54 in which the first hole part 54a is formed, and the outer strainer net which is installed to surround the inner strainer net 54 and the second hole part 52a is formed. (52).

Rainfall passing through the sieve (50) is passed through the outer sieve (52) and the inner sieve (54) in turn so that foreign matter contained in the rain is filtered twice.

The first hole portion 54a is formed smaller than the second hole portion 52a, and the second hole portion 52a formed in the external strainer 52 is formed in a long hole shape that is formed in a vertical direction to form a relatively large foreign matter. Even if the foreign matter is filtered and adhered to the second hole portion 52a, the drainage area can be sufficiently secured so that drainage can be made to another part.

Since the first hole 54a formed in the inner strainer 54 is relatively small, foreign matter having a small size passing through the second hole 52a can be effectively filtered.

The inner strainer net 54 is formed in a cylindrical shape with a bottom open, and the first hole 54a is continuously formed on the circumferential face and the upper face, and the passage hole 16a of the sedimentation tank 16 is the inner strain net 54. Is inserted into the bottom of the

Since the first hole 54a is disposed higher than the bottom surface of the immersion tank 16, foreign matter accumulated on the bottom surface of the immersion tank 16 does not flow into the main body 10 through the first hole 54a. Do not block the flow path of rainwater that is moved to the main body 10 through the first hole (54a).

Since the inner strainer 54 is inserted into the outer strainer 52, the outer strainer 52 is disposed to surround the first hole 54a of the inner strainer 54, so that the foreign matter accumulated in the sedimentation tank 16 is the outer strainer 16. Primary filtering by 52 and secondary filtering by inner strainer 54.

The outer strainer 52 is disposed to face the cover portion 70, and the curved portion 56 and the inner strainer 54 which allow the rainwater and foreign substances flowing through the cover portion 70 to slide in the lateral direction are inserted. The insertion hole portion 57 and the second hole portion 52a are formed to be formed between the vertical portion 58 into which rainwater flows, and the curved portion 56 and the vertical portion 58 and are inserted into the vertical portion 58. The inclined portion 59 is formed between the hole portions 57 and the second hole portion 52a is formed.

The curved portion 56 forms an upper surface of the outer filter net 52 and is formed to protrude convexly upwards, so that rainwater and foreign substances introduced into the sedimentation tank 16 through the cover portion 70 are curved to the curved portion 56. When it collides, it moves downward and falls downward.

The rainwater that has fallen in this way is freshwater in the sedimentation tank 16, and when the inflow of rainwater continues and the surface of the water rises, after passing through the outer filter network 52 and the inner filter network 54, the passage hole 16a passes through the main body 10. Falling to, and when the water surface of rainwater that is fresh water in the main body 10 rises is drained along the drain pipe 30 to the river or the peripheral drainage.

At this time, the foreign matter rising on the water surface of the rain is slid downward by the inclined portion 59 of the external sieve 52, it is possible to suppress the foreign matter such as fallen leaves adsorbed to the external sieve 52.

Accordingly, since the metal cover 72 can be opened one by one, the operator can move the cover 72 with relatively little force, and the cover 72 is rotatably supported by the support 74. 10, the cover 72 separated from the upper end of the main body 10 can be easily moved in the lateral direction of the main body 10.

In addition, the support 74 is formed with a sliding hole portion 78 in which the rotary shaft 76 installed in the main body 10 is movably inserted, so that the cover (7) is moved when the cover 72 is moved in the lateral direction of the main body 10. If the cover 72 continues to move further laterally after the 72 is primarily opened, the cover 72 further moves to the side of the main body 10 while the rotation shaft 76 moves along the sliding hole 78. As a result, the second opening is achieved.

Since the cover 72 can be moved farther from the top of the main body 10 in the lateral direction, the opening of the main body 10 is opened wider to remove foreign matter accumulated in the main body 10 and the immersion tank 16. In this case, it is possible to perform easy cleaning by the work vehicle.

And, it is possible to achieve the above technical configuration by installing the sedimentation tank 16 and the strainer 50 according to an embodiment of the present invention.

Therefore, the sump according to the prior art can be easily replaced with the sump according to an embodiment of the present invention can reduce the time and cost required to replace the sump.

As described above, replacing the sump according to the prior art with the sump according to an embodiment of the present invention can prevent the sediment settled inside the sump in the drain pipe 30 and the sump cover 70 ) Can be easily opened and closed so that the sediment deposited in the sedimentation tank 16 can be dredged easily and quickly using a mechanical dredging car and the like, thereby reducing dredging cost and time.

Looking at the operation of the sump according to an embodiment of the present invention configured as described above are as follows.

When rainwater flows through the entrance of the road or underground parking lot in rainy weather, rainwater flows through the cover part 70 and into the sedimentation tank 16. At this time, the cover part 70 is made of a mesh-shaped scaffold, which is relatively Large debris will be filtered out.

Rainwater introduced into the sedimentation tank 16 is fresh water from the bottom surface of the sedimentation tank 16 and the surface of the rainwater rises if the inflow of rainwater continues, and a part of the foreign matter contained in the rainwater accumulates on the bottom surface of the sedimentation tank 16. Foreign matter is filtered out.

If the surface of rainwater continues to rise, foreign matter floating on the surface of the water rises with rainwater, and this foreign matter is filtered by the external strainer 52, and the foreign matter passing through the outer strainer 52 is filtered by the inner strainer 54. do.

Rainwater that has passed through the sieve 50 is dropped to the bottom surface of the main body 10 through the passage hole 16a, and if the inflow of rainwater continues, the water surface rises to discharge the rainwater along the drain pipe 30.

At this time, the foreign matter passing through the strainer 50 accumulates on the bottom surface of the main body 10 so that the foreign matter is filtered once more from the main body 10.

If the foreign matter drainage action as described above is maintained for a long time, since the foreign matter accumulates on the bottom of the main body 10 and the sedimentation tank 16, a cleaning operation is performed, and when the cleaning operation is performed, an operator opens the cover 72 to the main body 10. When lifted apart from the jaw portion 14 of the support 74 is rotated around the rotating shaft 76, the cover 72 is moved to the outside of the main body 10 to achieve a primary opening.

Since the cover 72 is further pushed in the lateral direction of the main body 10 after the primary opening, the cover 72 further moves outward of the main body 10 while the rotation shaft 76 moves along the sliding hole 78. The secondary opening of the main body 10 and the immersion tank 16 is made.

When the cover 72 is completely open, the suction pipe is inserted into the main body 10 and the salivary tank 16 to suck foreign matter so that the cleaning operation can be performed. When the suction operation is completed, the cover 72 is returned to the main body 10. The cover 72 is seated on the jaw portion 14 of the main body 10.

At this time, the operator can open and close the main body 10 and the immersion tank 16 by the operation of pulling or pushing the cover 72 rotated by the support 74 so that a small number of workers can easily clean the work. do.
