Description
Technical Field
The utility model relates to a sluice field specifically is a keep off two floodgate systems of tide gate.
Background
The tidal barrier is a throttling project for inland rivers to enter the sea and has various tasks of water supply, tidal barrier, flood discharge, water stain reduction and the like. In order to discharge flood and reduce water damage in rainy season, the tidal gate needs to be opened and closed to rush drainage of waterlogging without dividing into day and night tide by tide, the opening and closing times of the gate are dozens of times or even more than one hundred times of the opening and closing times of a common sluice, the tidal force pressure is high, and the management cost is high; in dry seasons, in order to improve the utilization rate of water resources and reduce the engineering management cost, a set water level is often used as a trigger pointer for gate regulation, large-flow centralized drainage is adopted in individual periods, and the tidal gate engineering is controlled and applied in a manner of closing the gate in other periods, so that the river is cut off for a long time.
The conventional sluice control mode has the following problems: (1) the river cut-off causes the interruption of material flow and energy flow of the river, cuts off the connection between the inland river and the open sea, and has negative effects on both the inland river and the open sea, wherein the typical example is that a fish migration channel is cut off, and fishery resources in the inland river and the open sea are damaged; (2) the river is cut off, the water flow is not communicated, so that pollutants can be discharged and accumulated in a certain river section, fishes die in large scale due to nowhere escape, a food chain is broken, the extraction and conversion capacity of a river ecosystem on the pollutants in the water body is reduced, and the problem of river pollution is more serious; (3) the static water environment before the gate caused by closing the gate for a long time causes the dynamic balance of silt flushing and silting under the gate to shift to the silting direction, thus aggravating the problem of silting of river channels, which also becomes a common fault of the traditional sluice engineering.
The active tidal gate is designed, built and managed under the guidance of the traditional engineering water conservancy thought, is developed around the center of development and utilization of water resources, does not consider factors in water ecology, water environment and other aspects, and is a total source of a series of problems. In recent years, with the growing severity of river environment and ecological problems, it has become an industry consensus to relax river control, restore river integrity, achieve river continuity, and develop ecological water conservancy which can give consideration to economic, social and environmental comprehensive development. The traditional sluice engineering is limited by the existing structural form, the technical transformation space is limited, and the breakthrough in the aspect of developing ecological water conservancy has not been achieved. At present, some newly-built projects at home and abroad, such as London Thames river tidal barrier, Holland winterdan tidal barrier, Venice lake tidal barrier, Suzhou river gate and the like, adopt gates with specific structures according to the principle of minimum influence on rivers, but the projects still cannot get rid of auxiliary power and manual intervention components in the regulation and control process and cannot technically transplant a plurality of existing water gates.
In order to solve the above problems, domestic patent 201220023729.7 proposes a river channel control technical scheme using a rotary gate to cooperate with a main gate, which can theoretically solve the problem of excessive river channel control by a water gate, but some problems are also exposed in practical operation: the rotary gate crosses the water flow section of the gate chamber, aquatic weeds can be wound on the gate, and meanwhile, the gate closing force of the gate is small and cannot be adjusted along with the rise of the downstream water level, so that the problem that the gate cannot be completely closed due to the clamping stagnation of the aquatic weeds in operation and further the downstream high water flows backward is often caused.
