However, the existing inspection well has the following defects in actual use:
the pressure drain pipe has pressure, and long-time rivers wash and cause the damage to the wall of a well of inspection shaft, have reduced the life of inspection shaft.
Sediment in the inspection shaft can flow into the downstream drainage system along with the pipeline, so that the water cross section of the pipeline in the downstream drainage system is reduced, and the service life of the downstream drainage system is shortened.
Therefore, how to solve the problem that the inspection well is damaged due to flushing by the water flow with pressure and to reduce the blockage of the downstream drainage system caused by the sediment and dirt in the sewage is a technical problem that needs to be solved by those skilled in the art.

In order to achieve the above purpose, the utility model discloses an inspection well structure between a pressure drain pipe and a gravity drain pipe, which comprises a well body arranged under the ground; one side of the well body is connected with a pressure drain pipe, and the other side of the well body is connected with a gravity drain pipe; the sewage with pressure is discharged from the gravity drain pipe after entering the well body from the pressure drain pipe.
Wherein, the bottom of the well body is provided with a water retaining overflow wall;
the lower end of the water retaining overflow wall is connected with the bottom, two side edges are respectively connected with the side wall of the well body, and two surfaces with the largest area face to one side of the well body connected with the pressure drain pipe and the other side of the well body connected with the gravity drain pipe respectively;
the upper end of the water retaining overflow wall is positioned above the pressure drain pipe and the gravity drain pipe.
Preferably, the upper part of the well body is provided with an opening;
the opening is provided with a well lid.
Preferably, the other end of the pressure drain pipe is connected with a submersible pump at the bottom of the sewage water collecting well;
the submersible pump conveys the sewage in the sewage water collecting well into the well body through the pressure drain pipe.
More preferably, the sewage collection well is for receiving sewage from a basement.
The utility model has the beneficial effects that:

Detailed Description
Examples
As shown in fig. 1 and 2, the manhole structure between the pressure drain pipe and the gravity drain pipe comprises a well body 2 arranged under the ground 1; one side of the well body 2 is connected with a pressure drain pipe 3, and the other side is connected with a gravity drain pipe 4; the sewage with pressure is discharged from the gravity drain pipe 4 after entering the well body 2 from the pressure drain pipe.
Wherein, the bottom 5 of the well body 2 is provided with a water retaining overflow wall 6;
the lower end of the water retaining overflow wall 6 is connected with the bottom 5, two side edges are respectively connected with the side wall of the well body 2, and two surfaces with the largest area face to one side of the well body 2 connected with the pressure drain pipe 3 and the other side of the well body 2 connected with the gravity drain pipe 4 respectively;
the upper end of the water retaining overflow wall 6 is positioned above the pressure drain pipe 3 and the gravity drain pipe 4.
According to the utility model, the water retaining overflow wall 6 is added on the well body 2, the well body 2 is divided into two spaces, sediment deposition is facilitated, the bottom edge and the two side edges of the water retaining overflow wall 6 are respectively connected with the bottom 5 and the side wall of the well body 2, the upper end is not top, a gap of 600mm is arranged between the water retaining overflow wall and the opening of the well body 2, and water flow is facilitated.
The water retaining overflow wall 6 prevents water flow entering through the pressure drain pipe 3 from scouring the side wall of the well body 2, and prolongs the service life of the inspection well;
