1 to 7, the water collecting well according to the exemplary 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. The filtering net 50 is formed between the filter unit 50 and the blocking unit 51b and 54b for filtering foreign matter contained in the rainwater and preventing the foreign matter from rising, and partitions the inside of the main body 10 and the filtering net 50 is installed. It includes an acupuncture tank 16 in which a passage hole 16a is formed.

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 an inner strainer 57 installed in the through hole part 16a and a first strainer 51b and a first mesher 51a formed to surround the inner strainer 57. It includes an outer filter net 51, and a second outer filter net 54 is installed to surround the inner filter net 57, the second blocking portion 54b and the second mesh portion 54a is formed.

Rainfall passing through the sieve 50 is passed through the first outer sieve 51 and the inner sieve 57 in order to filter the foreign matter contained in the rain twice.

If foreign matter accumulates on the bottom surface of the sedimentation tank 16 and the surface of rainwater increases, the rainwater flowing into the sedimentation tank 16 passes through the first outer manure network 51 and the second outer manure network 54 and then the inner manure network ( It passes through the 57 and falls into the main body 10.

At this time, since the first blocking portion 51b prevents foreign matter that has passed through the first mesh portion 51a from rising along the surface of the water, the internal strainer 57 is prevented from being blocked by the foreign matter so that the foreign matter accumulates to some extent. Allow drainage.

An insertion hole portion 52 into which the inner strain network 57 is inserted is formed at an upper end of the first blocking portion 51b and a lower end of the first mesh portion 51a of the first outer strain network 51, and the first blocking portion 51b. The lower end and the first mesh portion 51a are disposed to be inclined to protrude outward.

Therefore, since the connecting portion between the lower end of the first blocking portion 51b and the upper end of the first mesh portion 51a forms a circular edge 53 protruding outward, the first blocking portion 51b is lowered downward. An inclined surface is formed, and the first mesh portion 51a forms an inclined surface that rises upward.

The first blocking portion 51b installed to be inclined in this way prevents foreign substances that rise along the rising surface from being caught by the first blocking portion 51b so that the upper portion of the inner strainer 57 is not blocked by the foreign substances.

In addition, the foreign matter falling on the upper surface of the first blocking portion 51b is allowed to slide downward along the first blocking portion 51b so that the foreign matter is prevented from moving to the inner strainer 57.

The second outer strain net 54 further includes an upper plate portion 56 opposite the cover portion 70, between the upper plate portion 56 and the second blocking portion 54b, and between the second blocking portion 54b and the first blocking portion 54b. The second mesh portion 54a is provided between the blocking portions 51b.

The second blocking portion 54b is disposed to be inclined in parallel with the first blocking portion 51b, and the second blocking portion 54b extends from the lower end of the second blocking portion 54b to the edge 53 of the first external filter net 51. Mesh portion 54a is provided.
As a result, the second external filter net 54 is continuously stacked on the first external filter net 51.

Therefore, it is possible to filter by the second mesh portion 54a so that foreign matter rising along the surface of the rainwater is increased and the foreign matter rising along the surface of the rainwater does not move to the inner strain network 57 side through the first blocking portion 51b.

In addition, when the surface of rainwater continues to rise and foreign matter rising along the water surface rises along the second blocking portion 54b, it is filtered by the second mesh portion 54a installed at the upper end of the second blocking portion 54b. .

The upper plate portion 56 passes through the cover portion 70 and changes the advancing direction of the foreign matter introduced into the sedimentation tank 16 in the lateral direction so that the foreign matter introduced into the sedimentation tank 16 directly into the inner strainer 57. Prevent contact.

The inner strainer 57 includes a mesh portion such as the first mesh portion 51a and the second mesh portion 54a, and the hole portion forming the mesh portion is formed to grow step by step from the bottom to the top.

Therefore, foreign matter of a small size accumulated on the bottom surface of the sedimentation tank 16 is prevented from passing through the lower part of the inner manure network 57, and at the same time the manure of the relatively large size rising along the surface of the manure mesh 57 The drainage interview should be wider toward the top of the.

Foreign matters of relatively small size, in particular, foreign matters with small grains and high specific gravity, such as soil and sand, accumulate on the bottom surface of the sedimentation tank 16 or move at a low depth, and foreign matters such as leaves having large and small specific gravity Since it is raised and floated, the size of the hole forming the mesh portion as described above is increased step by step to effectively filter out foreign matters and not to narrow the drainage area.

The cover part 70 includes a cover 72 seated in the opening of the main body, and a support 74 rotatably installed between the cover 72 and the main body 10.

Here, the cover 72 is composed of a plurality of blocks seated on the jaw portion 14 formed on the upper end of the main body 10, preferably a pair of cover 72 is installed on the upper end of the main body 10 Preferably, the support 74 is installed at the ends of the cover 72 facing each other is connected to the inner wall of the main body 10.

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 rotating shaft 76 installed in the main body 10 is movably inserted, so that the cover (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.

The technical configuration as described above can be applied to the construction of the sump well in a newly constructed area, but replacing the lid of the sump according to the prior art with the cover part 70 of the sump according to an embodiment of the present invention. 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.

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 the foreign matter is filtered by the first mesh portion 51a of the first external strain net 51 and passes through the first mesh portion 51a. One foreign material is filtered by the inner strainer (57).

Subsequently, if the rainfall of the rain continues to rise, the foreign matter rising along the surface of the water is filtered by the second mesh portion 54a, and the foreign matter falling downward after passing through the second mesh portion 54a is the first blocking portion ( Since it slides outward along 51b, it accumulates in the position separated by the length of the interrupting | blocking part 51b, 54b from the inner strainer 57. As shown in FIG.

The foreign matter accumulated from the bottom surface of the sedimentation tank 16 is slid out of the inner strainer 57 by the first barrier part 51b and the second barrier part 54b, thereby maintaining a gap with the inner strainer 57. And accumulate.

Therefore, even if foreign matter accumulated in the immersion tank 16 can be prevented from clogging the inner filter net 57 by the first blocking portion 51b and the second blocking portion 54b.

If the surface of the water is continuously raised, the second blocking portion 54b prevents the foreign matter from approaching the inner strainer 57 and prevents the foreign substance from rising along the surface so that the upper portion of the inner strainer 57 is not blocked.

Therefore, the foreign matter contained in the rainwater that passes through the sieve 50 is quaternary by the first mesh portion 51a, the first blocking portion 51b, the second mesh portion 54a, and the second blocking portion 54b. Since it is filtered over, it is possible to suppress the foreign matter from passing through the sieve 50, and at the same time, it is possible to suppress the clogging of the internal sieve 57 by the accumulation of the foreign matter.

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.
