[0002] The high-level regulating pool is an important protective facility for the hump-type pressure water pipeline system in water conservancy engineering. It can not only reduce the risk of water hammer phenomenon by adjusting pressure fluctuations and providing buffer space, but also cope with negative pressure phenomenon by preventing pipeline cavitation and maintaining system stability, thereby ensuring the safe, stable and efficient operation of the water pipeline system. However, the existing high-level regulating pool has the following problems in actual engineering: On the one hand, large high-level regulating pools for pressure delivery systems in water conservancy engineering usually require a large amount of land, which is particularly problematic for urban centers or areas with limited land resources. The construction of large high-level regulating pools may also limit the development of the surrounding area and affect the urban planning and construction of the surrounding area.

[0003] On the other hand, although the total volume of the high-level regulating pool is relatively large, due to the need to consider various factors (such as safety, stability, terrain, water level parameters, etc.) in its design, the effective volume available for water storage is relatively low. This to some extent reduces the water storage efficiency and utilization rate of the pool. SUMMARY

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] As shown in Figures 1-5 The present application proposes a high-level regulating water pool integrated on a pump house, which comprises a water intake pump house 10 provided with a pump house water inlet forebay 11 (a sunken water pool) and two high-level regulating water pools 1 installed on the roof of the water intake pump house 10, the water intake pump house 10 has an aboveground part and an underground part, a water intake pump is installed in the water intake pump house 10, and the water inlet pipe 10b of the water intake pump 10a extends into the pump house water inlet forebay 11. ​​Each high-level regulating water pool 1 is connected with water inlet pipeline 2, water outlet pipeline 3, overflow pipeline 4 and emptying pipeline 5 (with control valve), the water inlet of water inlet pipeline 2 is connected with the water outlet pipe 10c of water pump 10a in water pump house 10, and the water outlet of water inlet pipeline 2 extends into high-level regulating water pool 1, realizing water pumping; the water inlet of water outlet pipeline 3 extends into high-level regulating water pool 1, and its water outlet is connected with buried water pipeline 13 through elbow joint 14; the water inlet height of overflow pipeline 4 is consistent with the upper limit water level height of high-level regulating water pool 1, and the water inlet of emptying pipeline 5 is located at the lower part or bottom wall of high-level regulating water pool 1, so that the water in high-level regulating water pool 1 can be emptied, facilitating water discharge maintenance of high-level regulating water pool 1; in addition, overflow pipeline 4 and emptying pipeline 5 both extend downward into pump house water inlet forebay 11, so that the overflow water and emptying water can be used twice. The top wall of high-level regulating water pool 1 is provided with an inspection manhole 6 (a square hole with a length of 1m is adopted, and of course a round hole can also be adopted), a hole cover is arranged at the inspection manhole 6, a ladder is installed on the side wall of high-level regulating water pool 1 corresponding to the inspection manhole, facilitating inspection.

[0022] The high-level regulating water pool 1 is integrated and installed on the top of water pump house 10, without needing to newly increase additional land occupation, and also reducing the invalid volume from the ground to the elevation of the top of pump house, thereby solving the technical problems of the existing high-level regulating water pool 1, that is, large land occupation, high elevation and low effective volume, and ensuring stable operation of the pump station system.

[0023] In combination with Figures 1-2 and Figure 5 , overflow pipeline 4 and emptying pipeline 5 are installed on the front side of the water inlet side of water pump house 10 through a connecting frame, and the lower parts of overflow pipeline 4 and emptying pipeline 5 both extend into pump house water inlet forebay 11, realizing twice use of overflow water and emptying water. In addition, the water inlet end of overflow pipeline 4 is provided with a funnel-shaped water inlet 4a located in high-level regulating water pool 1 and two connecting elbow pipes and horizontal pipe sections 4b, the funnel-shaped water inlet 4a is connected with horizontal pipe section 4b through a connecting elbow pipe, and horizontal pipe section 4b is connected with vertical pipe section 4c of overflow pipeline 4 through a connecting elbow pipe, realizing overflow.

[0024] In combination with Figure 1 and Figure 4It can be seen that the inlet pipe 2 and the outlet pipe 3 are arranged on the back water wall F on the back water side of the water intake pump room 10 through the connecting frame. The inlet pipe 2 and the outlet pipe 3 are installed vertically or inclined through the connecting frame. The bottom of the outlet pipe 3 is connected to the buried water transmission pipe 13 through the elbow joint 14 to realize pressure transmission. The upper part of the inlet pipe 2 and the outlet pipe 3 bends horizontally and extends into the high-level regulating water tank 1. A guide wall 12 is set in the high-level regulating water tank 1 between the inlet pipe 2 and the outlet pipe 3. The guide wall 12 divides the high-level regulating water tank 1 into two, extends the water flow path, and makes the water flow in the tank stable.

[0025] In actual installation, the top opening of the vent pipe 5 is connected to the bottom wall of the high-level regulating water tank 1. The upper vertical section of the vent pipe 5 passes downward through the top wall of the water intake pump house 10, and its horizontal section extends outward from the upper part of the side wall of the water intake pump house 10 and bends outward, as detailed below. Figure 5 As shown.

[0026] In actual installation, the overflow pipe 4, vent pipe 5, inlet pipe 2, and outlet pipe 3 are all metal pipes. These pipes are connected to the side wall of the water intake pump house 10 via a connecting frame. The connecting frame is preferably a concrete pipe support structure, which includes a fixing ring M1 that mates with the pipe and a mounting plate M2 (vertically installed) fixed to the fixing ring M1. Taking the installation of the inlet pipe 2 as an example: [The text abruptly ends here, likely due to an incomplete sentence or missing information.] Figure 6 It is known that the mounting plate M2 is connected to the threaded steel bars pre-embedded in the water intake pump house 10; when the distance between the pipe and the side wall is large, a connecting plate M3 is installed between the mounting plate M2 and the fixing ring M1 to further ensure a reliable connection between the pipe support and the side wall. Of course, in actual installation, steel structure pipe supports or other pipe support structures that can achieve fixed installation of pipes and side walls can also be used, and the pipe support of the present invention is not limited to these.

[0027] Combination Figures 1-5 It is known that the elevated regulating water tank 1 is connected to the water intake pump house 10 through multiple rows of supports. A pre-embedded steel plate 9 is located on the bottom wall of the elevated regulating water tank 1 corresponding to each support. Concrete pads 8, corresponding to the supports, are poured on the top wall of the water intake pump house 10, and the supports rest on the concrete pads 8. In actual construction, the row of supports closest to the inlet pipe 2 uses fixed pot supports 7a to provide anchoring support for the elevated regulating water tank 1, while the remaining supports use bidirectional pot supports 7b to release deformation. This invention uses fixed pot supports 7a and bidirectional pot supports 7b to reliably transfer the load of the elevated regulating water tank to the top of the pump house, forming a clear force-bearing system, thereby improving the stability and safety of the elevated regulating water tank.

[0028] Combination Figure 1It can be seen that the interval between the two adjacent rows of supports is less than 5 m, the top wall of the water intake pump house 10 is cast with longitudinal and transverse intersecting beams 15, the supports are installed at the corresponding positions of the beams 15, and the stability and safety are improved.

[0029] In actual construction, the water intake pump house 10 and the pump house water inlet forebay 11 are constructed first, the longitudinal and transverse intersecting beams 15 are integrally cast on the top of the water intake pump house 10 during the construction of the water intake pump house 10, and the concrete cushion stones 8 are cast on the upper surface of the top wall of the water intake pump house 10 according to the design; wherein, during the construction of the water intake pump house, the through holes matched with the vent pipes are reserved on the top wall and the side walls to ensure the installation of the vent pipes; After the construction of the water intake pump house is completed, the pipes are fixed first, that is, the water inlet pipe 2, the water outlet pipe 3, the overflow pipe 4 and the vent pipe 5 are fixed to the side walls of the water intake pump house 10 by using the pipe supports; after the pipes are fixed, the supports are constructed on the concrete cushion stones 8, and then the high-level regulating water pool 1 (the top wall of the high-level regulating water pool 1 is cast last) and the flow guide wall 12 are cast, and the integrated installation of the high-level regulating water pool 1 is completed.

[0030] In actual projects, in order to improve the long-term waterproof performance of the high-level regulating water pool 1, the high-level regulating water pool 1 is cast by using self-compacting concrete with good waterproof performance, and then waterproofing membranes or waterproofing coatings are laid or brushed in the high-level regulating water pool 1 to ensure the waterproof performance of the high-level regulating water pool 1, and thus the long-term performance is ensured.

[0031] During operation, the water in the pump house water inlet forebay 11 is pumped by the water intake pump and input into the high-level regulating water pool 1, the water flow form is adjusted by the flow guide wall, and the water in the high-level regulating water pool 1 enters the buried input pipe through the water outlet pipe 3.

[0032] When the water level in the high-level regulating water pool 1 reaches the upper limit, the water is overflowed outward from the overflow pipe to the pump house water inlet forebay 11; when maintenance is needed, the control valve on the vent pipe 5 is opened to empty the high-level regulating water pool 1, the hole cover of the maintenance access hole 6 is opened, and then the maintenance in the high-level regulating water pool 1 can be performed.

[0033] Finally, it should be emphasized that the above description is only for the preferred embodiments of the present application and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, and for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified without creative labor, or some technical features can be replaced equivalently. Thus, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
