Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy facilities technology, and in particular to a rubber dam side pier structure that meets the ecological base flow requirements of rivers. Background Technology
[0002] Rubber dams, as low-head river-blocking structures, are widely used in river management projects due to their advantages such as low investment cost, short construction period, and simple operation. However, to meet river water storage requirements, newly constructed rubber dams typically require complete damming of the river channel. While this achieves the goals of raising water levels and increasing water storage capacity, it also brings serious problems. Because rubber dams block the natural flow channels of the river, the ecological base flow of the downstream river becomes difficult to maintain, posing a severe challenge to the river ecosystem.
[0003] The reduced water volume in downstream river channels has led to the destruction of aquatic habitats, threatening the survival of many aquatic organisms due to shrinking living space and deteriorating water quality, resulting in a decline in biodiversity. The weakened self-purification capacity of the river channel makes it difficult to dilute and degrade pollutants, exacerbating water pollution. Riverside vegetation withers and degrades due to water shortages, affecting riverbank stability and increasing the risk of soil erosion. These ecological problems not only damage the health of the river ecosystem but also negatively impact the ecological balance and sustainable development of surrounding areas. Utility Model Content
[0004] This utility model addresses the problems in the prior art by providing a rubber dam side pier structure that satisfies the ecological base flow of rivers, achieved through the following technical solution:
[0005] A type of rubber dam pier structure that meets the ecological base flow requirements of a river includes a rubber dam pier, an ecological base flow pipe, a control valve, and a valve well installed on the rubber dam pier. The inlet and outlet of the ecological base flow pipe are respectively located on the vertical wall of the rubber dam pier, with the inlet located on the upstream vertical wall of the pier and the outlet located on the downstream vertical wall of the pier. The valve well is installed on the bottom plate of the rubber dam pier, and the control valve is placed inside the valve well. The downstream flow rate of the ecological base flow pipe is adjusted by controlling the control valve to meet the ecological flow requirements of the river.
[0006] The valve well is integrated with the bottom plate of the rubber dam side pier and the vertical wall, and the size of the valve well meets the requirements for valve installation and daily operation.
[0007] The material of the ecological base flow pipe is selected according to the actual situation.
[0008] In summary, the beneficial technical effects of this utility model are as follows:
[0009] This utility model has a simple structure and is easy to install and use. By setting up an ecological base flow pipe and its supporting facilities on the side pier of the rubber dam, it can stably deliver ecological base flow to the downstream river channel. The precisely designed pipe diameter, the rationally planned inlet and outlet positions, and the flexibly adjustable control valves ensure that a suitable amount of water can be stably provided according to the ecological water demand of the downstream river channel under different seasons and water level conditions. This effectively alleviates the problem of the downstream ecological base flow being difficult to guarantee due to the obstruction of the river channel by the rubber dam, and effectively maintains the basic operation of the river ecosystem. Attached Figure Description
[0010] Appendix Figure 1 This is a schematic diagram of the overall structure of this utility model.
[0011] The labels shown in the attached diagram are: 1. Rubber dam side pier; 2. Ecological base flow pipe; 21. Inlet; 22. Outlet; 3. Control valve; 4. Valve well. Detailed Implementation
[0012] The present invention will be further described in detail below with reference to the accompanying drawings.
[0013] Example
[0014] like Figure 1 As shown, this utility model discloses a rubber dam side pier structure that meets the ecological base flow requirements of a river. It includes a rubber dam side pier 1, an ecological base flow pipe 2, a control valve 3, and a valve well 4 installed on the rubber dam side pier 1. The inlet 21 and outlet 22 of the ecological base flow pipe 2 are respectively located on the vertical wall of the rubber dam side pier 1, with the inlet 21 located on the upstream side pier wall of the rubber dam bag and the outlet 22 located on the downstream side pier wall of the rubber dam bag. The valve well 4 is installed on the bottom plate of the rubber dam side pier 1, and the control valve 3 is placed inside the valve well 4. By controlling the control valve 3, the downstream flow rate of the ecological base flow pipe 2 is adjusted to meet the ecological flow requirements of the river.
[0015] The valve well 4 is arranged in conjunction with the bottom plate and vertical wall of the rubber dam side pier 1, and the size of the valve well 4 meets the requirements for valve installation and daily operation.
[0016] The material of the ecological base flow pipe 2 is selected according to the actual situation.
[0017] The specific implementation method of this example is as follows: The inlet of the ecological baseflow pipe is located on the upstream pier wall of the rubber dam bag, and the outlet is located on the downstream pier wall. When the rubber dam impounds water, the water level upstream of the dam rises, creating a water level difference. With the control valve open, water flows into the ecological baseflow pipe through the inlet under the influence of the water level difference, and then flows from the outlet to the downstream river channel, supplementing the downstream ecological baseflow. The pipe diameter is determined based on the downstream river ecological baseflow and the upstream and downstream water levels, which ensures that the ecological baseflow pipe can stably deliver the amount of water needed for ecological purposes under different water level conditions.
[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
