Description

Technical Field

[0001] The utility model relates to a water inlet in a water conservancy project, specifically a layered water inlet combining a water intake tower and a vertical shaft. The water inlets are arranged in parallel and in layers on the side of the water intake tower, the water inlets are connected to water delivery pipelines, then merged into a main pipe, arranged along the wall of the vertical shaft, and finally combined with a water discharge tunnel at the bottom of the vertical shaft, and connected to the water delivery pipeline downstream. Background Art

[0002] When designing a reservoir project, a discharge tunnel is often set up to meet the requirements of emptying the reservoir or discharging floodwater. In particular, a reservoir whose water-blocking structure is an earth-rock dam type will have a tunnel with a discharge function. The tunnel is generally composed of an inlet section, an upstream tunnel section, a vertical shaft and a downstream tunnel section.

[0003] With the development of social economy, people have higher and higher requirements for the water quality of water sources, and more and more reservoirs have taken on the task of water supply. In order to meet the water supply requirements, a water transfer tunnel is generally set up, and the inlet adopts a shore tower type stratified water intake inlet or a shaft type water intake, and the downstream is connected to the water transfer tunnel. The bottom of the shore tower type stratified water intake inlet is flush with the water transfer tunnel. When the reservoir water level difference increases, the height of the tower body below the dead water level is large, resulting in a waste of slope excavation and tower body concrete pouring engineering. The bottom of the shaft type water inlet is flush with the water transfer tunnel, and there are problems such as large shaft stone excavation, large shaft concrete pouring engineering, and high gate hoist lift. Utility Model Content

[0004] The utility model aims to provide a stratified water intake inlet which is combined with a water intake tower and a vertical shaft of a water discharge tunnel. The stratified water intake inlet is reasonably arranged on the water intake tower, and the water inlet main pipe is connected to the water discharge tunnel by a vertical shaft pipeline. On the one hand, the requirements for stratified water intake within the effective water level fluctuation range of the upper reservoir water level can be maintained, and on the other hand, the height of the water intake tower and the gate lift can be reduced.

[0005] The technical solution adopted by the utility model is:

[0006] A stratified water intake inlet combining a water intake tower and a vertical shaft comprises a water intake tower, a vertical shaft and a water discharge tunnel. The water intake tower is combined with the vertical shaft and is located above the vertical shaft. The water intake tower comprises a water inlet, a tower body, a water delivery pipeline and a hoist. The tower body is a reinforced concrete structure. The water inlet is arranged on the side of the tower body. A number of water intake inlets can be arranged as needed according to the water level fluctuation range of the reservoir. Each water inlet is controlled by a gate, and the gate is connected to the water delivery pipeline. A hoist is arranged on the top of the water intake tower for each water inlet gate. The vertical shaft is located in the mountain of the water discharge tunnel inlet, and is formed by pouring concrete after the stone excavation of the vertical shaft. The upper part is connected to the water intake tower, and the lower part is connected to the water discharge tunnel. A number of water delivery pipelines behind the stratified water intake inlet of the water intake tower are combined and arranged inside the vertical shaft, and connected to the downstream pipeline along the inner wall of the water discharge tunnel.

[0007] Furthermore, when the water intake tower has more than three water inlets, the water pipelines connected to the water inlets are first merged into a horizontally arranged water main pipe, the outlet end of the horizontal water main pipe is connected to a vertically arranged water main pipe, and the vertical water main pipe is connected to the downstream pipeline along the inner wall of the drainage tunnel.

[0008] The beneficial effects of the utility model are:

[0009] 1. Strong adaptability to terrain. The base surface of the water intake tower does not need to be restricted by the bottom elevation of the water discharge tunnel, and can be set at any appropriate height above the water discharge tunnel, which can reduce the height of the water intake tower and the opening and closing height.

[0010] 2. The combination of water intake tower and shaft saves investment. The elevation of the opening and closing platform at the top of the conventional water intake tower is restricted by the design flood level, and the elevation of the bottom of the water discharge tunnel is restricted by the dead water level of water intake. Therefore, the engineering volume of the pure concrete bank tower or pure shaft excavation shaft-type water inlet is large, and it is difficult to achieve stratified water intake at the shaft-type water inlet. The reasonable combination of the tower height and the shaft height is more conducive to achieving a balance between stone excavation and use as concrete aggregate, saving investment.

[0011] 3. Multi-layered water intake has high efficiency. The water intake tower combined with the vertical shaft can flexibly set up multi-layered water intakes to adapt to the fluctuation of the reservoir water level at any time, so that the water intake can obtain high-quality water from the reservoir at any time, improving the water intake efficiency.
