Technical Field

[0001] The invention relates to the technical field of pump stations, in particular to a sluice pump station. Background Art

[0002] A low-head hydraulic structure built on rivers and channels that uses gates to control flow and adjust water levels. Closing the gates can block floods, tides, or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquatic products, environmental protection, industry, and domestic water. Opening the gates can discharge floods, waterlogging, abandoned water, or wastewater, and can also supply water to downstream rivers or channels. In water conservancy projects, sluices are widely used as structures for retaining, discharging, or taking in water.

[0003] The existing sluice pump station still has certain deficiencies in actual use: the existing sluice pump station is only suitable for concrete pouring during construction, but cement releases a large amount of heat during the concrete hydration process. If the heat is too high, temperature cracks may occur inside the concrete structure, which reduces the service life of the sluice pump station and poses a threat to the life safety of the staff. Based on the existing technical deficiencies, the present invention designs a sluice pump station. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The sluice pump station, through the sluice structure, is provided with a cement soil backfill layer, a stone layer, a first cushion layer and a second cushion layer inside the concrete when erecting the downstream wall, so that the stones and gravels can absorb part of the cement hydration heat, reduce the temperature inside the concrete, and thus reduce the generation of temperature cracks. At the same time, adding a proper amount of stones and gravels to the concrete can effectively reduce the amount of cement. At the same time, reducing the amount of cement can significantly reduce the project cost, thereby increasing the service life of the sluice pump station and avoiding danger to the staff;

[0017] 2. This kind of sluice pump station, through the sluice structure, through the setting of multiple high-pressure rotary jet piles, can spray cement slurry into the soil layer through the nozzle to mix with the soil, forming a continuous overlapping cement reinforcement body. This reinforcement body has high strength and can effectively share the load of the foundation under the gate to prevent foundation settlement and deformation;

[0018] 3. The sluice pump station can guide the water flow through the flow barrier wall and the setting of multiple flow barrier walls, so that the water flow can flow more smoothly in the main pump room. This helps to reduce the impact and wear of the water flow on the main pump room and extend the service life of the main pump room. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-3 An inspection bridge 47 is provided on one side of the outer surface of the three breast walls 44, and a stainless steel railing 48 is installed on one side of the three inspection bridges 47. A guardrail 5 is provided between the right wing wall 2 and the left wing wall 3, and a blanket 6 is provided on one side of the outer surface of the guardrail 5. An energy dissipation pool 7 is provided inside the downstream wall 1, and a diesel engine room 8 is provided on the left side of the energy dissipation pool 7.

[0027] The staff can be prevented from falling by the provision of the stainless steel railing 48. The kinetic energy of the water flow can be effectively reduced by the stilling basin 7, and this function enables the water flow to flow out smoothly when passing through the breast wall 44, rather than impacting the river bank or sluice facilities at high speed.

[0028] See also Figure 1 A conference room 14 is arranged inside the downstream wall 1, and a central control room 15 is arranged on one side of the conference room 14. A low-voltage distribution room 16 is arranged inside the downstream wall 1, and a high-voltage distribution room 17 is arranged on one side of the low-voltage distribution room 16.

[0029] Through the independent settings of conference room 14, central control room 15, low-voltage distribution room 16, high-voltage distribution room 17, high-voltage control room 18, lounge 19 and office 20, many benefits such as safety, professionalism, efficiency, comfort and management efficiency are improved. These independent settings not only meet the needs of sluice pump station operation, but also provide strong guarantee for its long-term stable operation.

[0030] Working principle: when a sluice pump station is used, when erecting the downstream wall 1, a cement soil backfill layer 45, a stone layer 49, a first cushion layer 410 and a second cushion layer 411 are arranged inside the concrete, so that the stones and gravels can absorb part of the cement hydration heat, reduce the temperature inside the concrete, and thus reduce the generation of temperature cracks. At the same time, adding an appropriate amount of stones and gravels to the concrete can effectively reduce the amount of cement. At the same time, reducing the amount of cement can significantly reduce the project cost, thereby increasing the service life of the sluice pump station and avoiding danger to the staff. At the same time, through the arrangement of multiple high-pressure rotary jet piles 46, cement slurry can be sprayed into the soil layer through the nozzle and mixed with the soil to form a continuous overlapped cement reinforcement body. This reinforcement body has high strength and can effectively share the load of the foundation under the gate to prevent the foundation from settling and deformation. Finally, through the arrangement of multiple flow separation walls 22, the water flow can be guided to flow more smoothly in the main pump room 13. This helps to reduce the impact and wear of the water flow on the main pump room 13 and extend the service life of the main pump room 13.
