Storage splicing plates 2 are inserted into both sides of the main functional box culverts 1. Sealing covers 3 are provided on the top of the storage splicing plates 2 and are inserted into the main functional box culverts 1. Adjacent storage splicing plates 2, the sides of the main functional box culverts 1, and the sealing covers 3 form a storage cavity 4. Several storage cavities 4 are interconnected. Storage driving equipment 5 and flushing driving equipment 6 are installed in one end of each storage cavity 4, and a collection pipe 7 is provided on the top of one end of the storage cavity 4. A collection pipe 8 is provided on the top of one of the storage cavities 4.

[0025] like Figures 2-3 As shown, the storage and regulation splicing plate 2 includes an outer support part 21, which is provided with a storage and regulation side sealing groove 211 around its perimeter. The outer support part 21 is adapted to the slope of the foundation pit. A partition part 22 is provided in the middle of the inner side of the outer support part 21, and a storage and regulation top sealing groove 221 is provided on the top of the partition part 22. The partition part 22 is provided with a T-shaped prism, which is assembled with the T-shaped groove on the outside of the main functional box culvert 1 to realize the connection between the main functional box culvert 1 and the storage and regulation splicing plate 2. The partition part 22 is provided with a connecting through hole 222 and a storage and regulation through hole 223. A rotating storage and regulation pipe 9 is provided in the storage and regulation through hole 223 through a bearing.

[0026] A drive gear ring 94 is provided on the outside of the rotary storage pipe 9. The drive gear ring 94 is connected to the first rotary drive motor 52 through gears to realize the rotation of the rotary storage pipe 9. This facilitates the placement of the water suction pipe 91 around the rotary storage pipe 9 when flushing the storage chamber 4, thus preventing the water suction pipe 91 from being bumped during the flushing process.

[0027] The storage drive device 5 includes a storage pump 51, a call pipe 7 connected to the outlet pipe of the storage pump 51, and two rotating storage pipes 9 connected to the inlet pipe of the storage pump 51. In this embodiment, two connected cavities share one set of equipment, which can be arranged according to actual needs.

[0028] The flushing drive device 6 includes a drive mechanism 61, a booster pump 62, and a suction pump 63. The inlet pipe of the booster pump 62 is connected to the outlet pipe of the storage pump 51, and the outlet pipe of the booster pump 62 is connected to the rotary flushing pipe 10.

One end of the rotary flushing pipe 10 is provided with a movable support 1001, and the other end of the rotary flushing pipe 10 is connected to the drive mechanism 61. The inlet pipe of the suction pump 63 is connected to the suction pipe 11, and the suction pipe 11 is provided with a suction head 111. The outlet pipe of the suction pump 63 is connected to the call pipe 7. The drive mechanism 61 includes a second rotary drive motor 611 fixed on the slider 612. The output shaft of the second rotary drive motor 611 is connected to the rotary flushing pipe 10. The other end of the rotary flushing pipe 10 is mounted on a sealing plate with a sealed bearing when the suction pipe 11 passes through the through hole 222. The sealing plate is mounted on the through hole 222 to prevent rainwater from entering the storage chamber 4 where the equipment is installed. The other end of the rotary flushing pipe 10 is rotatably mounted on the slider 612. The second rotary drive motor 611 is positioned opposite to the cam 614 of the reciprocating drive motor 613. The slider 612 is mounted on a limit slide rail by a return spring. Alternatively, a hydraulic cylinder can be used for repeated movement, eliminating the need for the limit slide rail and return spring.

[0029] During rinsing, the upper layer of clear liquid in the storage chamber 4 on one side can be used as rinsing water and sprayed out through the pressurized nozzle 1002 of the rotating rinsing pipe 10. At the same time, it reciprocates and rotates to achieve rinsing of the storage chamber 4. The sewage pump 63 is started to suck out the sewage through the sewage pipe 11 and discharge it through the call pipe 7.

[0030] like Figure 4 As shown, a first insertion part 31 is provided at one end of the sealing cover plate 3.

Cover sealing grooves 33 are provided on both sides of the sealing cover plate 3.

[0031] A filter plate 81 is installed at the top of the collection pipe 8 to prevent larger debris from entering the storage chamber 4. An inspection door 101 is installed on the side of the storage chamber 4 and the corresponding main functional box culvert 1 at one end to facilitate subsequent equipment maintenance.

[0032] The specific construction process is as follows:

[0033] Excavation of foundation pit: Excavate the foundation pit according to the actual project and anchor the slope of the foundation pit.

[0034] Main functional box culvert 1 splicing: The main functional box culvert 1 is spliced ​​along the axis of the pipe gallery. A sealing strip is set at the splicing point and waterproofing is carried out. After forming one end of the pipe gallery, the overall external waterproofing is carried out.

[0035] The splicing of the storage chamber 4: After backfilling the foundation pits on both sides of the main functional box culvert 1 and compacting the bottom, the storage splicing plate 2 is hoisted to both sides of the main functional box culvert 1 for splicing in sequence, and the sealing cover plate 3 is inserted for waterproofing.

[0036] Equipment installation: Install the equipment according to the equipment layout, and assemble longer pipelines by splicing.

[0037] Backfill the entire foundation pit.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
