Description

Technical Field

[0001] The present invention relates to the field of river water ecological technology, and in particular to a slightly elevated river water conservation sill and a water conservation scheduling method using the slightly elevated river water conservation sill. Background Art

[0002] The rapid development of urbanization and the increasing scope of urban development have made it difficult to guarantee the water level and water resources of rivers in slightly elevated areas. To create a good living environment, we must take into account the functionality of water ecology, water environment, and water landscape, meet the multifunctional needs of urban river networks and rivers, realize the interconnection of rivers between different terrains, expand the scope of water system connectivity, and at the same time guarantee the water resources and water level requirements of rivers, expand the scope of water environment and water ecology management, and achieve the comprehensive development of cities.

[0003] However, this type of water ecological management lacks effective technical means, often resulting in a cycle of deep digging of river channels, siltation, and further deep digging and repair, which wastes manpower and money and exhausts local governance. Alternatively, siltation is not repaired or managed, so when there is heavy rain, water cannot be drained, causing waterlogging. When there is less rain, the groundwater level drops rapidly. This vicious, unmanaged water cycle leads to ecological deterioration and complete loss of control. Reliance on natural rainfall results in the following consequences for the local water ecology: loss of river channel functionality, frequent droughts and floods, and a large volume of water conservancy projects.

[0004] The river channel of the slightly highland is downhill and connected to the river network at the end of the slope. Therefore, it is difficult for the water system of the slightly highland river channel to retain water on a daily basis, resulting in a lack of basic water resource conditions for the water ecology, water environment, and water landscape management of the water system of the slightly highland river channel. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to address the above-mentioned problems in the prior art and provide a water conservation bottom sill and water conservation scheduling method for micro-highland rivers, which maintains the water resources and ecological water level of rivers in micro-highland areas, meets the basic needs of water environment and water ecological management, and realizes the connectivity and smooth flow of river channels and river networks, and meets the multifunctional needs of urban rivers under special terrain conditions.

[0006] This application aims to solve one of the problems in the background technology.

[0007] The technical solution adopted by the present invention is: a water-retaining sill in a slightly elevated river channel, a water-retaining sill is set at the connection point between the downstream of the slightly elevated river channel and the river network, and the water-retaining sill is higher than both sides of the connection point.

[0008] A technical solution provided by this application also has the following technical features:

[0009] Preferably, the height of the water-retaining bottom sill is adjustable.

[0010] Preferably, a communicating vessel is provided on the water-retaining bottom bank, and the downstream of the slightly elevated river channel and the river network are connected via the communicating vessel.

[0011] Preferably, a gate is provided on the water-retaining bottom sill.

[0012] Preferably, the water-retaining bottom sill is composed of an adjustable water retaining dam.

[0013] Preferably, the water-retaining sill is formed by reshaping the river channel, or the water-retaining sill is composed of concrete.

[0014] Preferably, the river channel is reshaped by accumulating the river channel's own silt, sand, and gravel to form a water-retaining bottom bank.

[0015] Preferably, the water retaining bottom sill comprises two back-to-back L-shaped water retaining bases, and the middle parts of the two L-shaped water retaining bases are filled by sucking sand.

[0016] A scheduling method for water conservation in a slightly elevated river channel uses the aforementioned slightly elevated river channel water conservation sill; controls the elevation of the reshaped water conservation sill to control the water level of the river network and the water level of the slightly elevated river channel.

[0017] A technical solution provided by this application also has the following technical features:

[0018] Preferably, the river network pump station is connected to the slightly elevated river system, and the river network pump station draws water from the downstream river network and transports it to the slightly elevated river to adjust the water level of the slightly elevated river.

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention ensures water conservation in slightly elevated river channels by regulating water conservation in slightly elevated areas, using river network pumping stations to pump water, or by using water conservation sills to maintain water resources and ecological water levels required for river management and development, thereby meeting the functional requirements of the river channels.

[0021] 2. The present invention uses a water-retaining sill with adjustable height. When the water level exceeds the area above the water-retaining sill, the river network and the slightly elevated river channel are connected. After the natural connection, both are filled with sufficient water. The slightly elevated river channel diverts and stores the water of the river network. When the water level of the river network drops, the water in the slightly elevated river channel is blocked by the water-retaining sill. The slightly elevated river channel stores water at the same height as the water-retaining sill. This complementary drought and flood treatment improves the water ecology downstream of the slightly elevated river channel and also improves the water ecology of the river network. It realizes the interconnection between the river channel in the slightly elevated area and the large river network in the plain, expands the storage capacity, and combines multiple river functions such as raising water potential, increasing water volume, diverting water flow, and controlling water level.

[0022] 3. The water-retaining sill of the present invention provides a variety of ways to achieve the water-retaining sill, which can fully utilize the advantages of the terrain, simplify the scheduling operation as much as possible, and reduce the amount of engineering and engineering investment.

[0026] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention and are not intended to limit the present invention.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0029] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0030] like Figure 1 、 Figure 2 , a water-retaining sill in a slightly elevated river channel. A water-retaining sill is set at the place where the downstream of the slightly elevated river channel connects with the river network, and the water-retaining sill is higher than both sides of the connecting point.

[0031] The implementation of this structure can solve the problems of uncontrollable water resources and water levels, complex management and operation, insufficient ecological landscaping, and weak comprehensive functions in the micro-highland river channels with micro-topography. Through the scheduling method of this project, the basic requirements of water resources and water levels required for the water environment and water ecology management of micro-highland river channels can be achieved, the interconnection of river channels and river networks can be achieved, the storage area can be expanded, the micro-highland river channels can be utilized, and the diversification of river channel functions can be achieved.

[0032] Specifically, the height of the water-retaining bottom sill is adjustable; through this height change, the expected water level control height is obtained, and then the water storage capacity is controlled to achieve water ecological management.

[0033] Specifically, a communicating vessel is provided on the water-retaining sill, and the downstream of the slightly elevated river channel and the river network are connected through the communicating vessel; because in addition to overflow, water replenishment is also required when the water level is insufficient to overflow, specifically: when the water level is higher than the water-retaining sill, the upper overflow makes the water level heights on both sides of the water-retaining sill consistent. When the water level is not enough to overflow the water-retaining sill, if the water consumption downstream of the slightly elevated river channel causes the water level to drop rapidly, the communicating vessel can be used to replenish water to the slightly elevated river channel through the river network.

[0034] Specifically, a gate is provided on the water-retaining bottom bank; the gate is a reliable water control structure technology that is easy to implement.

[0035] Specifically, the water-retaining sill is composed of an adjustable water retaining dam; the adjustable water retaining dam is a reliable water control structure technology that is easy to implement.

[0036] Specifically, the water-retaining sill is formed by reshaping the river channel, or the water-retaining sill is composed of concrete; the specific material composition can be implemented according to local conditions to reduce manufacturing costs.

[0037] Specifically, the river channel is reshaped by the accumulation of silt, sand and gravel in the river channel itself to form a water-retaining bottom bank, reducing the impact on the river channel. It takes from the river channel and uses it in the river channel. If it is flushed, the flushed part can be used to maintain the river channel, that is, it is returned to the river channel, which has almost no impact on the ecology within the river channel.

[0038] Specifically, such as Figure 3 The water-retaining bottom sill includes two back-to-back L-shaped water retaining bases, and the middle parts of the two L-shaped water retaining bases are filled by sucking sand; this structure is a simple implementation method that can be implemented, which is convenient for manufacturing external components, namely L-shaped parts, which are cast with concrete and have steel bars inside; and filling sand between the two L-shaped water retaining bases is a simple and low-cost way to increase the resistance of the base.

[0039] A scheduling method for water conservation in a slightly elevated river channel uses the aforementioned slightly elevated river channel water conservation sill; controls the elevation of the reshaped water conservation sill to control the water level of the river network and the water level of the slightly elevated river channel.

[0040] like Figures 1 to 2 As shown, Figure 1 This is a schematic diagram of the location of the slightly elevated river channel and river network, which is connected to the surrounding river network through water pumps and water retention sills. Figure 2 It is a schematic diagram of the overall layout and scheduling method of the present invention.

[0041] It has the following characteristics: water pumps draw water from the river network and send it into the slightly elevated river channel to ensure water supply; a water-retaining bottom sill is formed by reshaping the terrain at the bottom of the slightly elevated river channel, reducing engineering measures such as gate construction and control, and realizing the functions of river network interconnection and water conservation and water level control; it provides water resource guarantee for the water environment and water ecology management of the river channel in the area, provides water level guarantee for the urban development and ecological landscape construction in the area, maintains the physical connection between the slightly elevated river channel and the river network, and the orderly flow of water bodies; it is suitable for urban rivers with high requirements for water ecology, water environment, and water landscape and diversified functional requirements required for development in slightly elevated terrain and landform areas; it lays a good foundation for urban construction, helps urban ecological construction, and meets the construction requirements of low-carbon and environmentally friendly cities.

[0042] The following steps are also included:

[0043] First, in daily operation, water resources from larger river networks are pumped into the target river channel in the micro-highland area to meet the basic water resources required for the micro-highland river channel function and the development of the surrounding areas;

[0044] Second, reshape the riverbed topography downstream of the slightly elevated areas and construct a water-retaining sill to ensure the water resources and water level required for the development of the river and surrounding cities. This sill will be used to control the water level and retain water.

[0045] Third, based on higher-level plans such as local urban planning, flood control and drainage planning, and national land space planning, and in combination with the river channel function and the water level requirements of the surrounding regional economic and social development, the elevation of the water-retaining sill should be determined. Through the overflow of the sill, the river can be interconnected with the downstream river network, integrated into the river network, and expand the regulation and storage capacity. This will ensure the overall communication between the river channel and the river network while controlling the water level.

[0046] Fourth, by conserving and controlling water in rivers in slightly elevated areas and interconnecting them with river networks, the fluidity and connectivity of water bodies are increased, the comprehensive storage capacity is expanded, and rainfall is stored, which is beneficial to flood control and drainage safety in urban areas.

[0047] Fifth, the bottom of the river channel is reshaped according to the terrain and topography to build a water-retaining bottom bank, reduce project investment, simplify project scheduling, and effectively achieve water conservation and control in the river channel. It is suitable for rivers in slightly highland areas with higher requirements for river channels.

[0048] Specifically, the river network pumping station is connected to the slightly elevated river system, and the river network pumping station draws water from the downstream river network and transmits it to the slightly elevated river to adjust the water level of the slightly elevated river;

[0049] Specifically, the present application can also be implemented in this way: through appropriate engineering measures and scheduling operation modes, water conservation and storage in micro-highland areas with relatively micro-topography can be achieved, limited water resources can be fully utilized, the multifunctionality of the water system can be achieved, and the ecological water resources and ecological water level of the river can be guaranteed; the structure includes: a micro-highland river system, a plain water system, a water inlet, a water outlet, a pumping station, and riverbed topography reshaping. The control method for achieving controllable ecological water level of the water system in the micro-highland area is carried out through the following steps:

[0050] First, the micro-highland river system is connected to the river network pumping station, which draws water from the downstream river network to the micro-highland river inlet;

[0051] Second, the terrain of the downstream of the slightly high river channel and the location where it connects to the river network will be reshaped. By partially raising the riverbed elevation to form a sill, the water retention and ecological water level of the slightly high river channel system will be guaranteed;

[0052] Third, water will be pumped to the slightly elevated river system through pumping stations to raise the water level of the slightly elevated river, maintain a suitable water level for water ecological and environmental management of the slightly elevated river, and connect the slightly elevated river system with the river network through sill overflow, thus achieving full interconnection between the water system and the river network in special areas;

[0053] Fourth, by controlling and reshaping the bottom sill elevation, controlling the water level of the water system, discharging flood water into the river network during the flood season, preventing floods during the flood season, and conserving water on a daily basis.

[0054] By adjusting the river system and engineering scheduling methods in the micro-highland areas, the water volume and water level of the rivers in the micro-highland areas can be maintained to provide basic water resource conditions for the water ecology and water environment. The coverage of the river network can be expanded by utilizing the topographic characteristics of the micro-highland areas.

[0055] The following technical effects can be achieved: the present invention realizes the daily connection between the micro-highland river system and the surrounding river network, and has a storage function during the flood season, giving full play to the terrain advantages of the micro-highland river system. While realizing water conservation and storage, it also has multiple functions such as water lifting, increasing water volume, water flow diversion, and water level control, thereby expanding the physical information connection between the river network and the micro-highland river system and promoting the orderly flow of water.

[0056] By reshaping the riverbed to form a sill, the project cost is reduced, the problems of large water resource loss and difficulty in water conservation in slightly highland areas are solved, daily water conservation is achieved, and flood season regulation is taken into account. The overflow of the sill is connected to the river network. Limited engineering measures have achieved the multifunctionality of the water system, reduced the construction of water conservancy project buildings, and greatly reduced construction costs.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
