The square hole 6 of the perforated side plate I 301 is a water outlet 8, and the square hole 6 of the perforated side plate II 302 is a water inlet 9, and the positions of the water outlet 8 and the water inlet 9 correspond. The upper left part of the partition 4 is provided with a water passing square hole 7, which is also a 300mm×300mm square hole, and is 100mm away from the upper side and the left side of the perforated side plate 3.

[0029] Specifically, the partition 4 is the same component as the perforated side plate 3, and the size of the partition 4 is also 2000mm×2000mm. When installing, the perforated side plate I 301 or the perforated side plate II 302 can be turned over to become the partition 4, and the water outlet 8 or the water inlet 9 can also be used as the water passing square hole 7.

[0030] On the basis of the above embodiment, as a preferred embodiment, inner ear blocks 10 for supporting the cover plate 5 are welded at the four corners of the top of the sedimentation tank unit. The cover plate 5 is placed on the inner ear blocks 10 with the four corners thereof, so that the cover plate 5 covers the top of the side plate to protect the sedimentation tank unit.

The welding of the side panels with holes 3 and the bottom plate 1, the welding of the side panels with holes 3 and the side panels without holes 2, and the welding of the side panels without holes 2 and the bottom plate 1 requires a 5mm welding position to be reserved on the outside. It is required that all welding parts between steel plates and between the inner ear block 10 and the surrounding steel plates are fully welded on both sides.

[0036] Step 2: Excavate the earth according to the placement of the sedimentation tanks (three sedimentation tanks are required) and pour C15 concrete cushion layer at the bottom to seal the bottom.

[0037] Step three, after the three sedimentation tanks are brought into the site, they are hoisted into place in pairs according to the connection between the water inlet 9 and the water outlet 8 and placed on the cushion layer to complete the assembly, and the outer side is backfilled and compacted.

[0038] Step 4: The water inlet 9 and the water outlet 8 of the overall structure are connected to the project drainage ditch.

[0039] Step 5: The inner ear block 10 is used as a steel plate support. When installing the cover plate 5, the four corners of the cover plate 5 need to be placed on the inner ear block 10. After completion, the top of the cover plate 5 is flush with the top of the sedimentation tank unit to avoid the risk of bulging after the cover plate 5 is covered and causing tripping of pedestrians. The steel fence 503 serves as a load-bearing plate for protection and aesthetics.

[0040] Step six: During the later construction and use process, sand and gravel will be deposited in each sedimentation tank. After a period of time, the sand can be pumped out with a sand pump or dug out manually.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
