Description

Technical Field
The invention relates to the field of town drainage, in particular to an overflow water storage and drainage control well with an elongated high-enclosure and a water storage and drainage method.
Background
In urban rainwater drainage, rainwater storage and drainage combination is an effective way to improve drainage capacity and water resource utilization. In the case that a gentle slope large-capacity water storage pipeline is paved in a construction area to store and drain rainwater, in order to store the rainwater, a connecting pipeline of the overflow outer row of the tail end well is higher than the water storage pipeline, but is limited by the elevation of the soil covering and other pipelines outside, and the elevation of the connecting pipeline is reduced; or the tail end well overflows through the retaining wall in the well chamber to drain rainwater, but the height of the retaining wall is reduced to prevent the overflow water from exceeding the top of the well chamber under the condition that the width of the well chamber is limited to ensure that the retaining wall cannot be lengthened. The other condition is that peak rainwater is introduced into the water storage facility from an external rainwater pipeline inspection well through a high-level connecting pipeline or a connecting pipeline after a retaining wall is arranged, and the problems of pipeline crossing and excessive overflow water height are also related, and the condition that the heights of the connecting pipeline and the retaining wall are reduced is faced. Both conditions affect the water storage height and the effect of collecting peak rainwater, and increase investment and management difficulty. In addition, when rainwater is collected from a rainwater pipeline in a water storage lake, if water enters from a high-level connecting pipeline, the initial low-level rainwater cannot flow in, and the water supplementing requirement of daily rainfall of the water storage lake cannot be met; if water is fed from the low-level connecting pipeline, the peak rainwater of heavy rainfall is temporary, and the water storage lake is full of water, so that the effect of regulating the peak rainwater cannot be achieved. In the flood season rainfall, the existing facilities can not meet the requirements of daily water replenishing and peak rainwater collection at the same time.

a handle lever (29) arranged in the overflow chamber (9) for actuating a gate insert (27), the gate insert (27) being used for closing or opening the channel (22) in the second retaining wall (16).
9. A drainage method of an elongated high-enclosure overflow storage and drainage control well, the elongated high-enclosure overflow storage and drainage control well comprising:
an overflow chamber (9) communicating with the first rainwater pipeline (13);
a drainage chamber (11) communicating with a second rainwater pipeline (13 '), the second rainwater pipeline (13') being connected to a water storage facility;
two parallel trapezoid overflow grooves (56) which are fixed on the inner side of the well wall (40) and are positioned at the upper part of the overflow chamber (9) are used for increasing the overflow area of rainwater and reducing the overflow thickness of the rainwater through the retaining wall;
The drainage method comprises the following steps:
during rainfall, rainwater of the first rainwater pipeline (13) flows into an overflow chamber (9) of the overflow water storage and drainage control well with the extended high-enclosure;
When the water level of the rainwater flowing into the overflow chamber (9) from the first rainwater pipeline (13) is higher than the overflow height of the overflow chamber (9), the overflow chamber (9) overflows the rainwater from the first rainwater pipeline (13) to the drainage chamber (11) by using the trapezoid overflow groove (56);
The rainwater overflowed into the drainage chamber (11) is discharged to the water storage facility via the second rainwater pipeline (13'), and the water storage facility stores peak rainwater of the rainwater pipeline (13).
10. An elongated high-enclosure overflow water storage and drainage control well, comprising:
a drainage chamber (11) for connecting a rain manhole (12) via a pipe;
An overflow chamber (9) for communicating with the accumulation drain pipe (14);
two parallel trapezoid overflow grooves (56) which are fixed on the inner side of the well wall (40) and are positioned at the upper part of the overflow chamber (9) are used for increasing the overflow area of rainwater and reducing the overflow thickness of the rainwater through the retaining wall;
a pump drainage chamber (10) located between the drainage chamber (11) and the overflow chamber (9);
a first retaining wall (17) for separating the drainage chamber (11) from the pump drainage chamber (10), wherein a channel (22) for communicating the drainage chamber (11) with the pump drainage chamber (10) is arranged at the bottom of the first retaining wall (17);
A second retaining wall (16) separating the pump discharge chamber (10) from the overflow chamber (9);
Two parallel rectangular overflow grooves (57) which are connected to the inner side of the well wall (40) and are positioned at the upper part of the pump row chamber (10), wherein the trapezoidal overflow grooves (56) are connected with the rectangular overflow grooves (57);
a gate (27) provided in the pump discharge chamber 10 for closing or opening the passage (22); and
A handle lever (29) for actuating the fork strap gate (27).
