具体实施方式Detailed ways
下面将结合附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
下面将对本申请蓄洪区进退洪协同调度方法的具体实施过程进行详细描述，步骤如下：The specific implementation process of the coordinated flood control method for flood storage areas in this application is described in detail below. The steps are as follows:
(1)服从蓄洪区所在流域防洪规划，确定蓄洪区分洪规模，分洪规模至少包括蓄洪区的分洪水位，蓄满历时以及蓄满水位。(1) The flood control plan of the river basin where the flood storage area is located shall be followed to determine the scale of flood diversion in the flood storage area. The scale of flood diversion shall at least include the flood diversion water level, full storage duration and full storage water level of the flood storage area.
本申请所确定的蓄洪区分洪规模，其为服从所在流域洪水调度安排的分洪规模。本实施例中，利用MIKE软件构建流域水动力数学模型，利用流域水动力数学模型对流域水文进行数值模拟，来确定蓄洪区分洪规模。具体的，耦合流域内河道，泵站以及蓄洪区等来构建流域水动力数学模型，利用流域水动力数学模型进行洪水典型年调算，分析提出流域超额洪水处理方案，并确定蓄洪区分洪规模，即服从流域洪水调度安排的分洪规模。The flood diversion scale of the flood storage area determined in this application is a flood diversion scale that is subject to the flood dispatching arrangement of the basin. In this embodiment, the MIKE software is used to construct a basin hydrodynamic mathematical model, and the basin hydrodynamic mathematical model is used to perform numerical simulation of the basin hydrology to determine the flood diversion scale of the flood storage area. Specifically, the basin hydrodynamic mathematical model is constructed by coupling the river channels, pumping stations and flood storage areas in the basin, and the basin hydrodynamic mathematical model is used to perform typical flood year adjustment, analyze and propose a plan for handling excess floods in the basin, and determine the flood diversion scale of the flood storage area, that is, the flood diversion scale that is subject to the flood dispatching arrangement of the basin.
(2)蓄洪区和生态湿地统筹兼顾，确定蓄洪区的进退洪方式。(2) Take into account both flood storage areas and ecological wetlands and determine the flood entry and exit methods of the flood storage areas.
目前，蓄洪区进洪方式包括扒口进洪和建闸进洪。退洪有开闸退洪和关闸泵站抽排2种方案。扒口进洪进水水头差大，洪水破坏力强，往往存在进洪无法有效管控，复堵困难，退洪速度难以满足生产生活恢复需求等问题，且及时性差。建闸进洪能及时有效地分洪，且便于灵活调度和多次启用，在退洪时可以根据洪水情况控制退水，尽快排出蓄洪区内底水，为生态湿地正常运行提供有利条件。经比对分析，本申请优选建闸进洪，即当发生超标准洪水时，开闸进洪，缓解城市周边区域防洪压力；退洪时，适时关闸运用圩内泵站抽排。At present, the flood storage areas have two ways of flooding: flooding through ditches and flooding through sluices. There are two options for flood discharge: opening the sluices to discharge the water and closing the sluices to pump out the water. The head difference of flooding through ditches is large, and the flood is highly destructive. There are often problems such as the inflow cannot be effectively controlled, re-blocking is difficult, and the flood discharge speed is difficult to meet the needs of production and life recovery, and the timeliness is poor. Building sluices to flood can effectively divert floodwaters in a timely and effective manner, and is convenient for flexible scheduling and multiple activation. When the flood is discharged, the water can be controlled according to the flood situation, and the bottom water in the flood storage area can be discharged as soon as possible, providing favorable conditions for the normal operation of the ecological wetland. After comparative analysis, this application prefers to build sluices to allow flooding, that is, when an excessive flood occurs, the sluices are opened to allow flooding to relieve the flood control pressure in the surrounding areas of the city; when the flood is discharged, the sluices are closed in time to use the pumping stations in the dikes to pump out the water.
(3)蓄洪区和生态湿地统筹兼顾，确定进退洪位置。(3) Take into account both flood storage areas and ecological wetlands and determine the locations of flood entry and exit.
蓄洪区进退洪的主要目的是削减洪峰流量和分蓄洪水，故进洪闸应建于上游，退洪闸建于下游；考虑到不同蓄洪区的地形地貌，也可选择进洪闸和退洪闸合建。在确定进洪闸和退洪闸具体闸址时，还应考虑进退洪过程中尽可能减少对湿地的冲刷破坏。本申请采用河工物理模型进行模拟，对闸址进行比选，从进洪工况泄流能力，流速分布及水流流态，通航水流条件等方面提出进退洪位置建议。河工物理模型是分析水闸过流的常规技术手段，其通过将实物等比例缩小来构建实物模型，通过对实物模型模拟水闸过流，来分析水闸过流。The main purpose of flood inlet and outlet in flood storage areas is to reduce peak flood flow and store flood water, so the flood inlet gate should be built upstream and the flood outlet gate should be built downstream; considering the topography of different flood storage areas, the flood inlet gate and the flood outlet gate can also be built together. When determining the specific sites of the flood inlet and outlet gates, it should also be considered to minimize the scouring and damage to the wetlands during the flood inlet and outlet process. This application uses a river engineering physical model for simulation, compares the gate site, and proposes recommendations for the flood inlet and outlet locations from the aspects of discharge capacity under flood inlet conditions, flow velocity distribution and water flow pattern, and navigation conditions. The river engineering physical model is a conventional technical means to analyze the flow of sluices. It constructs a physical model by reducing the actual object in proportion, and analyzes the flow of sluices by simulating the flow of sluices on the physical model.
根据进退洪闸的防洪、进(退)洪等特点，结合地形、地质条件、水流流态、控制运用等因素，在有限的范围内尽量使进(退)洪闸进出水流顺畅，工程量较小，投资省。一种优选方案为：设计进洪，退洪工况水闸泄量满足规划要求，且各闸孔流速分布较均匀，水闸上下游水流平顺，总体流态良好。工程易实施，投资经济合理。生态湿地蓄洪区考虑进退洪过程中要考虑减少对湿地的冲刷破坏。According to the flood control, flood inlet (outlet) and other characteristics of the flood gate, combined with factors such as terrain, geological conditions, water flow pattern, control and application, the water flow in and out of the flood gate is as smooth as possible within a limited range, with a small amount of engineering and low investment. An optimal solution is: the discharge of the flood gate under the design flood inlet and flood outlet conditions meets the planning requirements, and the flow velocity distribution of each gate hole is relatively uniform, the water flow upstream and downstream of the sluice is smooth, and the overall flow pattern is good. The project is easy to implement and the investment is economically reasonable. Ecological wetland flood storage areas should consider reducing the scouring and damage to the wetlands during the flood inlet and outlet process.
(4)构建生态湿地蓄洪区。(4) Construct ecological wetland flood storage areas.
本申请基于蓄洪区及其周边的现状地形地貌，因地制宜地进行工程布局。具体的，因地制宜，构建自适应、自恢复和自调节能力强的生态湿地。不采用大开挖、大水面的湿地型式，而是根据现状地形地貌，遵循最小工程量原则，因地制宜的进行工程布局，可将地势较低的作为湿地净化区，地势较高的区域作为林草湿地区。并筛选合适的植物进行配置，具体为，植物选择中，利用新闻报道、实景照片、水毁统计等资料对流域发生大水后存活的植物进行整理，建立植物选择正面清单表。优先从清单表中筛选满足湿地净化区和林草湿地区的耐水淹植物，为生态湿地尽快恢复打下基础。基于上述即可获得自适应，自恢复以及自调节能力强的生态湿地。This application is based on the existing topography and landforms of the flood storage area and its surrounding areas, and the project layout is adapted to local conditions. Specifically, adapt to local conditions and build ecological wetlands with strong self-adaptation, self-recovery and self-regulation capabilities. Instead of adopting wetland types with large excavations and large water surfaces, the project layout is adapted to local conditions based on the existing topography and landforms and the principle of minimum engineering volume. The lower terrain can be used as wetland purification areas, and the higher terrain areas can be used as forest and grass wetland areas. And select suitable plants for configuration. Specifically, in plant selection, use news reports, real-life photos, water damage statistics and other information to sort out plants that survived floods in the basin, and establish a positive list of plant selection. Priority is given to selecting flood-resistant plants that meet the requirements of wetland purification areas and forest and grass wetland areas from the list, laying the foundation for the rapid recovery of ecological wetlands. Based on the above, an ecological wetland with strong self-adaptation, self-recovery and self-regulation capabilities can be obtained.
(5)蓄洪区进退洪协同调度。(5) Coordinated dispatching of flood water in and out of flood storage areas.
生态湿地蓄洪区主要有3种工况：进洪工况，退洪工况和湿地运行工况。There are three main operating conditions in ecological wetland flood storage areas: flood inflow conditions, flood outflow conditions and wetland operation conditions.
在进洪工况下，服从防汛指挥部统一调度开启进洪闸。具体的，当流域发生超标准洪水且下游受顶托明显影响洪水下泄时，开启进洪闸。进洪后，可根据流域防洪要求灵活调度，适时关闭闸门，以保留蓄洪空间，便于再次利用。Under flooding conditions, the flood gates will be opened in accordance with the unified dispatch of the flood control headquarters. Specifically, when the basin has an excessive flood and the downstream is significantly affected by the top support, the flood gates will be opened. After the flood, the gates can be flexibly dispatched according to the flood control requirements of the basin and closed in time to retain the flood storage space for reuse.
在退洪工况下，以服从流域整体防洪安排为原则，并结合内外水位差对堤防及建筑物安全影响等因素，开启退洪闸退水。当流域水位下降至警戒以下且退水缓慢，或为尽快恢复圩内生产生活，可关闭退洪闸，开启圩内泵站抽排底水。Under flood discharge conditions, the flood gates are opened to discharge water in accordance with the overall flood control arrangements of the basin, and in combination with factors such as the impact of the internal and external water level difference on the safety of embankments and buildings. When the water level in the basin drops below the warning level and the water is discharged slowly, or in order to resume production and life in the dike as soon as possible, the flood gates can be closed and the pumping stations in the dike can be opened to pump out the bottom water.
在湿地运行工况下，关闭进洪闸和退洪闸，开启湿地进水闸，将流域水体通过配水干渠引入生态湿地蓄洪区，自流进入各湿地单元，经湿地单元进行净化后，最终从排水站抽排至流域。在湿地运行工况下，蓄洪区作为生态湿地运行，发挥湿地净化、生态修复等的作用，有利于促进流域生态环境的改善。Under the operating conditions of the wetland, the flood gates and flood discharge gates are closed, and the wetland inlet gates are opened to introduce the basin water into the ecological wetland flood storage area through the water distribution main canal, and flow into each wetland unit by gravity. After being purified by the wetland unit, it is finally pumped out from the drainage station to the basin. Under the operating conditions of the wetland, the flood storage area operates as an ecological wetland, playing the role of wetland purification and ecological restoration, which is conducive to promoting the improvement of the basin's ecological environment.
实施例Example
本实施例以十八联圩蓄洪区为目标蓄洪区，十八联圩蓄洪区为巢湖流域规划9处蓄洪区之一，十八联圩蓄洪区的分洪水位，蓄满历时以及蓄满水位应服从巢湖流域洪水调度安排。利用MIKE软件建立巢湖流域水动力数学模型，并耦合流域内河道，泵站和蓄洪区等，通过典型年模型调算，对比分析巢湖闸上超额洪水处置方案，确定目标蓄洪区的分洪水位，蓄满历时和蓄满水位。本实施例中，分洪水位采用巢湖50年一遇洪水位12.75m，蓄满历时3天(对应进洪流量450m3/s)，最高蓄洪水位同巢湖百年一遇洪水位13.36m。In this embodiment, the Shibalianwei flood storage area is taken as the target flood storage area. The Shibalianwei flood storage area is one of the 9 flood storage areas planned in the Chaohu Basin. The flood diversion water level, full storage duration and full storage water level of the Shibalianwei flood storage area should be subject to the flood dispatch arrangement of the Chaohu Basin. The hydrodynamic mathematical model of the Chaohu Basin is established by using MIKE software, and the river channels, pumping stations and flood storage areas in the basin are coupled. Through typical year model adjustment, the excess flood disposal plan on the Chaohu sluice is compared and analyzed to determine the flood diversion water level, full storage duration and full storage water level of the target flood storage area. In this embodiment, the flood diversion water level adopts the 50-year flood level of Chaohu Lake, which is 12.75m, and the full storage duration is 3 days (corresponding to the flood flow of 450m 3 /s). The highest flood storage level is the same as the 100-year flood level of Chaohu Lake, which is 13.36m.
本实施例中，进洪闸和退洪闸为合闸，设置于目标蓄洪区的沙河口下游约200m处的南淝河左堤。进洪闸和退洪闸的泄量满足规划要求，且各闸孔流速分布均匀，水闸上下游水流平顺，总体流态良好。且该区域堤后为已建二期湿地工程中的沉淀塘，水面宽200～450m，进退洪时解决了双向消能防冲的难题，消能效果良好。In this embodiment, the flood gate and the flood gate are closed and are set on the left bank of the Nanfei River about 200m downstream of the Shahekou in the target flood storage area. The discharge of the flood gate and the flood gate meets the planning requirements, and the flow velocity of each gate hole is evenly distributed, the water flow upstream and downstream of the sluice is smooth, and the overall flow state is good. In addition, behind the embankment in this area is a sedimentation pond in the second phase wetland project that has been built, with a water surface width of 200 to 450m, which solves the problem of two-way energy dissipation and anti-scouring during flood inflow and outflow, and the energy dissipation effect is good.
本实施例中，所筛选的耐水淹植物包括但不限于沉水植物(例如轮叶黑藻，金鱼藻)，挺水植物(例如水稻，芦苇)，浮叶植物(例如莲，菱属)，以及木本植物(例如池杉，水杉)。湿地净化区选择沉水植物和浮叶植物进行配置，林草湿地区选择挺水植物和木本植物进行配置。In this embodiment, the flood-resistant plants selected include but are not limited to submerged plants (such as Hydrilla verticillata and Ceratophyllum), emergent plants (such as rice and reed), floating-leaf plants (such as lotus and Trapezium), and woody plants (such as pond cypress and metasequoia). Submerged plants and floating-leaf plants are selected for configuration in the wetland purification area, and emergent plants and woody plants are selected for configuration in the forest and grass wetland area.
当南淝河或巢湖洪水位明显下降，在不影响流域整体防洪安排，并结合内外水位差对堤防及建筑物安全的影响等因素，开启退洪闸进行退水。当巢湖水位降至警戒水位10.5m以下，且蓄洪区内退水缓慢，为尽快恢复圩内生产生活，关闭退洪闸，开启蓄洪区内泵站抽排，以尽快排出底水。本实施例中，目标蓄洪区总排涝流量40.95m3/s，约9天时间，能将圩内涝水从10.5m降至8.6m，泵站排涝规模和排涝设施基本满足尽快恢复湿地正常运行的需求。When the flood level of Nanfei River or Chaohu Lake drops significantly, the flood gates are opened to drain water without affecting the overall flood control arrangements in the basin, and in combination with the impact of the internal and external water level difference on the safety of embankments and buildings. When the water level of Chaohu Lake drops below the warning water level of 10.5m, and the water in the flood storage area is draining slowly, in order to restore production and life in the embankment as soon as possible, the flood gates are closed and the pumping station in the flood storage area is opened to drain the bottom water as soon as possible. In this embodiment, the total drainage flow of the target flood storage area is 40.95m3 /s. In about 9 days, the water in the embankment can be reduced from 10.5m to 8.6m. The drainage scale and drainage facilities of the pumping station basically meet the needs of restoring the normal operation of the wetland as soon as possible.
