Detailed Description
The invention will be further described with reference to the drawings and the following examples, but the scope of the invention is not limited thereto.
As shown in figure 1, a sewage lifting well for reforming transform construction project, including inlet tube 1, outlet pipe 2, breather pipe 3, breather pipe casing 4, grid 5, sewage elevator pump 6, quarter wall 7 and access hole 8.
As shown in fig. 1 and 2, a water inlet pipe 1 and a water outlet pipe 2 are respectively arranged at two ends of an underground lifting well, and an access hole 8 is arranged at the upper part of the lifting well; one end of the vent pipe 3 is communicated with the access hole 8, the other end of the vent pipe extends to the ground and is provided with a vent pipe cover 4, so that smooth air circulation in the well can be ensured, and the pressure is stable. A short wall 7 is arranged in the lift well, a grid 5 is arranged at the top of the short wall 7, and the short wall 7 and the grid 5 divide the inner space of the lift well into two parts, namely a first well pool 9 and a second well pool 10; inlet tube 1 and first wellhole pond 9 intercommunications, the volume ratio of first wellhole pond 9 and second wellhole pond 10 is 2: 1; first well pond can deposit the granule impurity in the sewage, and the floater in the sewage can be filtered to grid 5. A sewage lifting pump 6 with a cutter device is arranged in the second well pool 10, and the water outlet of the sewage lifting pump 6 is connected with the water outlet pipe 2; in actual construction, the overall height of the lift shaft and the short wall 7 is set according to the parameters of the sewage lift pump 6.
