[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments. Example

[0033] Please refer to Figure 1-11, which shows a multifunctional river-blocking sluice station irrigation and drainage structure, including two embankment concrete roads 1 arranged side by side between the inner and outer rivers. Retaining walls 2 are set on the opposite sides of the two embankment concrete roads 1, and a foundation pit is set between the two retaining walls 2. The retaining wall 2 can be straight or arc-shaped, or a combination of the two.

[0034] The foundation pit is provided with an inlet 3, a sewage treatment facility 5, a forebay 6, a pump house 7 and a water outlet 8 which are interconnected and arranged in sequence along its width.

[0035] Pump room 7 is equipped with units and upstream and downstream control gates to meet the needs of unit installation, operation, maintenance and management.

[0036] The forebay 6 increases the water exchange coefficient of the unit, has a rectangular plane, and adopts a retaining wall 2 structure.

[0037] The water inlet 3 faces the inner river and includes a bottom protection 31 that gradually decreases in height toward the bottom of the foundation pit, a water diversion and irrigation section 32, a drainage section 33, a flood discharge section 34, and a self-draining section 35. The water outlet faces the outer river and includes a first stilling basin 81, a sea cover 82, and an anti-scouring groove 83.

[0038] The outlet 8 faces the outer river and includes a first stilling pool 81. An overbank 82 and an anti-scouring groove 83 may also be provided in the outlet 8 to reduce the scouring of the riverbed by the flood during discharge.

[0039] The through-embankment box culvert 4 includes a gate shaft 41, a second flood control gate 42, a culvert 43, a second energy dissipation pool 44, as well as opening and closing equipment, racks, an opening and closing machine room, etc.; a turning connection section is used to adjust the direction of water flow, and piers are set in the middle when necessary. The second flood control gate 42 controls the entrance and exit of the culvert 43 independently. The gate shaft 41, the culvert 43 and the second energy dissipation pool 44 pass through the embankment and connect to the outside; a second flood control gate 42 is set in the through-embankment box culvert 4 to control the connection of the various sections of the culvert 43 inside it.

[0040] One end of the water diversion and irrigation section 32 of the water inlet portion 3 is connected to the gate well 41 , and one end of the drainage section 33 , the flood discharge section 34 and the self-drainage section 35 are connected to the sewage treatment facility 5 .

[0041] A sewage cleaning facility 5 is set between the dike box culvert 4 and the forebay 6. The sewage cleaning facility 5 is equipped with a sewage cleaning rack 51, a sewage conveyor belt 52, a sewage cleaning rack bridge 53, etc. The dike box culvert 4 is perpendicular to the center line of the sewage cleaning facility 5, and the two are connected by an arc-shaped retaining wall 2, with a partition pier in the middle.

[0042] A traffic bridge 10 is provided between the two embankment top concrete roads 1 .

[0043] The front pool 6 includes an irrigation and drainage pool 61, a flood drainage pool 62 and a self-draining pool 63. The culverts 43 of the dike box culvert 4 connecting the irrigation and drainage pool 61, the flood drainage pool 62 and the self-draining pool 63 are independent of each other.

[0044] The self-draining gate 9 includes a gate chamber 91, a first flood control gate 92 and a valve.

[0045] The pump house 7 is provided with a flow channel layer, a water pump layer and a motor layer. Water enters the flow channel, and water is discharged through the drainage unit 72 pipeline and the flood discharge unit 73 flow channel, with the units arranged in the middle. A self-draining gate 9 is provided on the right side of the pump house 7. After the first flood control gate 92 is started and lifted, the flood water in the self-draining pool 63 flows to the outlet part 8 and is discharged into the outer river. The drainage unit 72 pumps out the flood water in the drainage and irrigation pool 61 and discharges the flood water in the dike into the outer river through the drainage hole. When the water level of the inner river channel is low, the water from the outer river is diverted through the water inlet layer channel of the pump house 7, the dike box culvert 4, etc. into the dike for irrigation.

[0046] The flood discharge unit 73 pumps out the river flood in the flood discharge pool 62. Upstream and downstream gates 74 are set on the water inlet and outlet sides of the pump room 7. The main power building and auxiliary rooms are arranged on the motor layer. The vertical wall between the water outlet on the outer river side of the drainage and flood discharge pump room 7 and the auxiliary rooms forms a breast wall. The self-draining gate 9 is also equipped with a breast wall. The first flood control gate is set outside the breast wall. When the water level of the outer river is high, the gate can be lowered to play a role in flood control.

[0047] An overflow pipe 93 is installed on the soil-facing side of the self-draining gate 9. This overflow pipe 93 bypasses the first flood control gate 92 and connects the upstream and downstream sides of the self-draining gate 9. When the inland river water level is higher than the external river water level, the overflow pipe 93 drains the water from the self-draining pool 63 into the first stilling basin 81 after the water level reaches the limit. The self-draining gate 9, which is equipped with a breastwork first flood control gate 92, lowers its gate when the external river water level is high, providing flood control. The overflow pipe 93 overflows at any time when the inland river water level is high, ensuring water storage in the inland river while avoiding frequent opening and closing of the gate. A valve is also installed on the overflow pipe 93 to prevent backflow when the external river water level is high.

[0048] The waste cleaning facility 5 includes a waste cleaning rack 51, a waste conveyor belt 52, a waste cleaning rack bridge 53, etc.

[0049] In the above embodiment, except for the overflow pipe 93 and the duct 43 which are steel structures, the rest are reinforced concrete structures with a strength grade of not less than C25.

[0050] The working principle of the present invention is:

[0051] During flood control, the upstream and downstream gates 74, the water diversion and irrigation gate 75 corresponding to the pump house 7 and the first flood control gate 92 corresponding to the self-draining gate 9 are lowered to form a flood control circle with the embankments on both sides of the outlet side.

[0052] During drainage, the second flood control gate 42 (right fan) corresponding to the dike box culvert 4 is opened, and the drainage unit 72 is started. The water flows from the dike channel → the dike box culvert 4 → the drainage section 33 (the turning connection section) → the sewage treatment facility 5 → the forebay 6 → the pump room 71 → the water outlet 8 → the outer river. At the same time, the water diversion irrigation gate 75 on the outer river side of the water inlet layer connecting the channel of the pump room 71 is lowered.

[0053] During flood discharge, the corresponding flood discharge unit 73 is started, and the upstream and downstream gates 74 are opened. The water flows from the inner river → the sewage treatment facility 5 → the forebay 6 → the pump room 71 → the water outlet 8 → the outer river.

[0054] During self-drainage, the first flood control gate 92 corresponding to the self-draining gate 9 is opened, and the water flows from the inland river → self-draining gate 9 → water outlet 8 → outer river; when the first flood control gate 92 is closed, it can overflow through the overflow pipe 93, ensuring water storage in the inland river while avoiding frequent opening and closing of the gate.

[0055] During irrigation, the water diversion irrigation gate 75 on the outer river side of the water inlet layer connecting the pump room 7 corresponding to the pump room 7 and the second flood control gate 42 of the inner river embankment box culvert 4 are opened to divert the outer river water and the inner river water into the channel inside the dike respectively.

[0056] The construction method of the present invention is:

[0057] Pump room: Excavate foundation pit → foundation treatment (if necessary) → lay cushion layer, tie steel bars, cast bottom plate → tie steel bars, cast side walls, middle piers, partition piers → tie steel bars, cast water pump layer, motor layer, indoor floor layer, top plate, racks, corbels, etc. → backfill earth on both sides → tie steel bars, cast factory buildings, equipment rooms, etc. → install lifting equipment. The construction sequence of upstream and downstream buildings is similar.

[0058] When backfilling the earth, the earth on all sides is backfilled evenly and synchronously, and the area within 2m is compacted manually and with mechanical equipment.

[0059] The above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications may be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the claims of the present invention.
