In some embodiments, a climbing ladder 14 is provided under the top cover 15 of the water inlet chamber 6 and the water outlet well 2, and the climbing ladder 14 is vertically arranged on the inner wall. The climbing ladder 14 is arranged on the inner wall of the water inlet chamber 5 and the water outlet well 2, which is convenient for the staff to work in the well.

In some embodiments, the bottom of the water inlet well 1 and the water outlet well 2 is provided with a sand and pebble backfill layer 11, and the sand and pebble backfill layer 11 can precipitate a part of sand, filter the sewage, and slow down the silt caused by the sand to the pipeline. Blocking.

In some embodiments, the water inlet end of the inverted siphon 4 is higher than the water outlet end of the inverted siphon 4 , which facilitates the discharge of sewage and prevents backflow of water.

The use process of the utility model embodiment is as follows:

When the structure is normally drained, the sewage flows into the water inlet chamber 6 from the water inlet pipe 12, passes through the sedimentation tank 10 and the sand and pebble backfill layer 11, and enters the filter chamber 7 through the transition port 8, and the sewage is filtered through the basket 92 The sundries flow into the inverted siphon 4, and then flow into the outlet well 2, through the secondary sedimentation of the sand and pebble backfill layer 11 and the sedimentation tank 10, and flow out from the outlet pipe 13 to the downstream pipeline. When the amount of sewage increased, the water level rose, and the sewage flowed through the inverted siphon 4 and the overflow pipe 3 simultaneously. When the inverted siphon 3 needs to be overhauled or maintained, the valves 16 at both ends of the inverted siphon 3 are closed to block the water flow, the water level continues to rise, and the sewage enters the overflow pipe 3 after being filtered by the basket cover 91, and then enters the outlet well 2 and passes through Outlet pipe 13 flows out.

Although the utility model has been described in detail with general description and specific examples above, some modifications or improvements can be made on the basis of the utility model, which will be obvious to those skilled in the art. Therefore, the modifications or improvements made on the basis of not departing from the spirit of the utility model all belong to the protection scope of the utility model.
