Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments.

Referring to fig. 1-3, an interchange culvert gate combining pumping station water diversion and drainage comprises a pump room 1, a rear pool 2, an interchange culvert 3, an interchange culvert gate 4, a stilling pool 5, a splayed retaining wall 6 and a connecting channel 7;

the pump house 1 is connected with a rear pool 2 and an interchange culvert 3, the rear pool 2 and the interchange culvert 3 are of an upper-layer structure and a lower-layer structure, the upper layer is the rear pool 2, the lower layer is the interchange culvert 3, the interchange culvert 4 and an upper-layer mechanical discharge gate 41 are connected with the rear pool 2, a lower-layer self-discharge gate 42 is connected with the interchange culvert 3, the interchange culvert 4 is connected with a stilling pool 5, the splayed retaining wall 6 is connected with two side edges of the stilling pool 5, and the stilling pool 5 is connected with a connecting channel 7 through the splayed retaining wall 6;

the gate chamber of the overpass culvert gate 4 is of an integral structure and comprises an upper-layer mechanical drainage gate 41 and a lower-layer self drainage gate 42, wherein the mechanical drainage gate 41 is used for draining the rear pool waterlogging, and the self drainage gate 42 is used for draining the outside river water.

The elevation of the bottom plate of the mechanical discharge gate 41 is consistent with that of the rear pool 2, and the elevation of the bottom plate of the self-discharge gate 42 is consistent with that of the overpass culvert 3;

the bottom plate of the machine row gate 41 is respectively provided with a machine row gate 411 and a machine row gate hoist platform 412 for hoisting the machine row gate 411; a self-discharging gate 421 and a self-discharging gate hoist platform 422 for hoisting and lowering the self-discharging gate 421 are respectively arranged on the bottom plate of the self-discharging gate 42, and the self-discharging gate 411 and the self-discharging gate 421 are both positioned on one side of the stilling pool 5;
