Description

Technical Field

[0001] This utility model relates to a layered water intake tower structure in water conservancy and hydropower projects, specifically a cylindrical layered water intake tower structure built into the gate slot section in the water inlet of a reservoir project or water diversion project. Background Technology

[0002] In hydraulic and hydropower projects, tiered intake towers are a common type of hydraulic intake structure, primarily used in reservoirs or lakes. They allow for tiered water intake by setting intake orifices at different heights, enabling flexible adjustment of the intake depth or drawing water from specific layers based on water level changes. Conventional tiered intake towers are typically rectangular in plan view, with stepped gates in longitudinal section. They are characterized by large longitudinal dimensions, high cost, and poor aesthetic appeal, which is more pronounced when the gate orifices at each level are relatively small.

[0003] Chinese patent CN210315447U discloses a cylindrical layered water intake tower. The tower has several inlet structures at different elevations on its exterior, communicating with the interior of the tower body. An outlet structure is located at the bottom of the tower body. The tower body connects to a water conveyance tunnel via these inlet structures. Compared to conventional rectangular water intake towers, this design is simpler and requires less construction work. However, because the gate openings are located outside the main body, the overall structure is dispersed, resulting in poor aesthetics, cumbersome formwork, and difficulty in arranging the top platform's gate control room. During operation, the dead angle formed by the three protruding gate openings on the outside of the well ring and the outer surface of the well ring easily traps floating debris from the reservoir surface, making dredging difficult and further impacting the reservoir's landscape.

[0004] For reservoir projects, tiered intake towers, as prominent single concrete structures within the reservoir area, have a significant impact on the natural landscape. Furthermore, the size and scale of the tiered intake towers directly determine the project scope and cost. In addition, the arrangement of the gate slots greatly influences the layout of the upper opening and closing structure and the ease of formwork erection. Considering all these factors, it is necessary to further optimize and improve the existing tiered intake tower structure. Utility Model Content

[0005] The purpose of this utility model is to improve the shortcomings of conventional rectangular layered water intake towers, such as poor aesthetics and large engineering workload, while taking into account the convenience of construction formwork and the layout of the upper gate opening and closing machine room. It proposes a cylindrical layered water intake tower with the gate slot section built in. On the one hand, the gate slots of each layer of water intake are embedded in the main tower body, and the overall structure is cylindrical, which is small in size, low in cost and good in appearance. On the other hand, after the gate slot section is built in, the concrete structure is concentrated, the construction formwork is convenient, and the opening and closing equipment is concentrated, which makes the layout of the gate opening and closing machine room convenient.

[0006] The technical solution adopted in this utility model is:

[0007] The cylindrical, tiered water intake tower built into the gate slot section mainly includes the tower body, water intake structure, and gate hoisting room. The tower body is the main structure of the tiered water intake tower, with a hollow water passage structure on the inner side, a maintenance platform at the top, and an anti-scour base plate at the bottom. Ventilation pipes and water level pipes are embedded inside the tower body, leading to the maintenance platform. The water intake structure includes an intake orifice, a gate slot, an outlet orifice, and a water conveyance tunnel. The intake orifices are located at different elevations and orientations on the tower body, while the outlet orifice is located at the bottom of the tower body and connects to the water conveyance tunnel. The gate slot is built into the tower body, with a thin reinforced concrete wall on the outer side. A reinforced concrete water-retaining breast wall is constructed above the intake orifice on the inner side of the gate slot, leading to the maintenance platform. The gate hoisting room is located above the maintenance platform, supported by columns on the tower body. A steel ladder allows access between the maintenance platform and the gate hoisting platform. A fixed winch-type gate hoist is installed on the gate hoisting platform for lifting the gate.

[0008] Furthermore, the tower body has a cylindrical shape, and the hollow water-passing structure is square in shape, giving the overall tower body a "circle on the outside and square on the inside" appearance.

[0009] Furthermore, the shape of the water-passing structure in the inner cavity of the tower can be adjusted according to actual needs without affecting the structural function.

[0010] Furthermore, depending on the foundation conditions, the anti-scour base plate may be treated with measures such as enlarging the foundation and consolidation grouting.

[0011] Furthermore, the water intake orifice is divided into three layers: upper, middle, and lower. The lower layer water intake orifice is arranged on the side facing forward with the water flow, the middle layer water intake orifice is arranged on the side with higher terrain, and the upper layer water intake orifice is arranged on the side with lower terrain.

[0012] Furthermore, the location of the water intake openings can be adjusted according to the terrain, and the number of openings can be increased or decreased according to the actual needs of the project.

[0013] Furthermore, a fixed trash rack is provided on the outside of the water intake opening, and a cantilevered support platform is provided at the bottom of the trash rack.

[0014] Furthermore, a precast reinforced concrete cover plate is provided on the top of the gate slot, with an opening in the center of the cover plate to facilitate the lifting of the gate.

[0015] Furthermore, the prefabricated cover plate can be made of steel, composite materials, etc.

[0016] Furthermore, the opening and closing platform can also be equipped with a circular track and a mobile lifting device.

[0017] Furthermore, the steel ladder can be a central column type rotating steel ladder, or a steel climbing ladder or telescopic ladder, etc.

[0018] Furthermore, the maintenance platform is connected to external traffic via a traffic bridge.

[0019] The beneficial effects of this utility model are:

[0020] 1. Excellent overall aesthetics. The structure of this utility model is cylindrical in shape and almost perfectly symmetrical on the plane, which conforms to the aesthetic concept of the general public. The circular outer contour is not easy for floating objects on the reservoir surface to accumulate. At the same time, the structure of this utility model is small in size and does not stand out in the reservoir area, resulting in a good landscape effect.

[0021] 2. Smaller scale and lower cost. Compared to conventional rectangular tiered water intake towers, the cylindrical tiered water intake tower with its built-in slot has a more compact structure, resulting in a smaller size, less project scope, and lower cost. Based on calculations from actual engineering projects, the investment for a rectangular tiered water intake tower is 9.671 million yuan, while this new structure costs only 5.107 million yuan, representing a 47.2% saving in investment.

[0022] 3. Good structural stability. Compared with conventional rectangular layered water intake towers, the cylindrical structure has balanced stiffness in all directions, which can evenly distribute the effects of external forces such as water pressure and wind and wave loads, and the structure has strong anti-sliding and anti-overturning capabilities.

The tower body 1 is the main structure of the layered water intake tower, and its appearance is cylindrical. The inner side of the tower body 1 is a square cavity water passage structure 11, and the overall planar shape presents an "outer circle and inner square" appearance. Water intake openings 21 are set at different elevations and in different orientations on the tower body 1. The water intake openings 21 are divided into three layers: upper, middle, and lower. The lower layer openings are arranged on the side with the water flow forward, the middle layer openings are arranged on the side with higher terrain, and the upper layer openings are arranged on the side with lower terrain. The bottom is provided with a water outlet 23 connected to the water conveyance tunnel 24. The top of the tower body 1 is a maintenance platform 12. Safety guardrails 16 are installed around the maintenance platform 12. The maintenance platform 12 is connected to external traffic through a traffic bridge 4. The bottom of the tower body 1 is an anti-erosion base plate 13. A vent pipe 14 and a water level pipe 15 are buried inside the tower body 1 to the maintenance platform 12. The lower part of the vent pipe 14 is connected to the water conveyance tunnel 24.

[0033] The water intake structure 2 includes an intake orifice 21, a gate slot 22, an outlet orifice 23, and a water conveyance tunnel 24. A fixed trash rack 25 is installed on the outside of the intake orifice 21, and a cantilevered support platform 26 is installed at the bottom of the trash rack 25. To ensure aesthetics, the gate slot 22 is built into the tower body 1, and a reinforced concrete thin wall 27 is installed on the outside.

The gate hoisting platform 34 is equipped with a fixed winch-type gate hoisting machine 32 for gate lifting.

[0035] The specific implementation process of this utility model is as follows: When water needs to be taken from a specific water level, the hoisting hoist 32 fixed in the hoisting room 3 lifts the water-blocking gate in the built-in gate slot 22 of the water intake orifice 21 at the corresponding elevation. Water flows from the water intake orifice 21 into the cavity water passage structure 11, and then flows into the water conveyance tunnel 24 through the water outlet 23, thereby achieving the purpose of stratified water intake.

[0036] The shape of the water-passing structure 11 inside the inner cavity of the tower body 1 can be adjusted according to actual needs without affecting the structural function.

[0037] Depending on the foundation conditions, anti-impact base plate 13 may be treated with measures such as enlarging the foundation and consolidation grouting.

[0038] The location of the water intake openings 21 can be adjusted according to the terrain, and the number of openings can be increased or decreased according to the actual needs of the project.
