One situation is that a gentle slope large-capacity water storage pipeline is laid in a construction area to bear the storage and drainage of rainwater, in order to store rainwater, a connecting pipeline arranged outside a tail end well overflow is higher than a water storage pipeline, but is limited by the elevation of covering soil and other external pipelines, and the elevation of the connecting pipeline is reduced; or the tail end well overflows the outer rainwater drainage through the retaining wall in the well chamber, but the height of the retaining wall is reduced in order to prevent the height of the overflowing water from exceeding the top of the well chamber under the condition that the retaining wall cannot be lengthened due to the width of the well chamber. The other situation is that peak rainwater is introduced into a water storage facility from an external rainwater pipeline inspection well through a high-level connecting pipeline or a connecting pipeline arranged behind a retaining wall, and the problems of pipeline crossing and overhigh height of overflow water are also involved, so that the height of the connecting pipeline and the height of the retaining wall are reduced. Both of these two conditions affect the water storage height and the effect of collecting peak rainwater, increasing the investment and management difficulty.

9. A drainage method of a lengthened high-enclosure overflow storage drainage control well comprises the following steps:
an overflow chamber (9) communicated with the first rainwater pipeline (13);
a drain chamber (11) communicated with a second rainwater pipeline (13 '), wherein the second rainwater pipeline (13') is connected with a water storage facility;
the two parallel trapezoidal overflow chutes (56) are fixed on the inner side of the well wall (40) and positioned at the upper part of the overflow chamber (9) and are used for increasing the rainwater overflow area and reducing the thickness of rainwater overflowing through the retaining wall;
the drainage method comprises the following steps:
when raining, rainwater in the first rainwater pipeline (13) flows into an overflow chamber (9) of the lengthened high-enclosure overflow water storage and drainage control well;
when the level of rainwater flowing into the overflow chamber (9) from the first rainwater pipe (13) is higher than the overflow height of the overflow chamber (9), the overflow chamber (9) overflows the rainwater from the first rainwater pipe (13) to the drain chamber (11) by means of the trapezoidal overflow groove (56);
the rainwater overflowing into the drain chamber (11) is discharged to the water storage facility via the second rainwater pipe (13'), and the water storage facility stores the peak rainwater of the rainwater pipe (13).
10. The utility model provides a drainage control well is held in overflow that increases height encloses, its characterized in that includes:
a drain chamber (11) connected to the rainwater inspection well (12) via a pipe;
an overflow chamber (9) communicated with the storage and discharge pipeline (14);
the two parallel trapezoidal overflow chutes (56) are fixed on the inner side of the well wall (40) and positioned at the upper part of the overflow chamber (9) and are used for increasing the rainwater overflow area and reducing the thickness of rainwater overflowing through the retaining wall;
when raining, rainwater in the storage and discharge pipeline (14) enters the overflow chamber (9); when the water level of the rainwater flowing into the overflow chamber (9) from the storage and discharge pipeline (14) is higher than the overflow height of the overflow chamber (9), the rainwater in the storage and discharge pipeline (14) overflows to the drain chamber (11) by using the trapezoidal overflow groove (56) until the water level of the rainwater in the overflow chamber (9) is lower than the overflow height of the overflow chamber (9), so that the storage and discharge pipeline (14) can continuously store and discharge the rainwater on the ground, and the water accumulation on the ground is avoided; rainwater overflowing into the drainage chamber (11) is discharged to a rainwater inspection well (12) via a pipe.
