Technical Field
The utility model relates to the technical field of hydraulic engineering, in particular to a flood control wall structure with a regulation and storage function.
Background
Along with the development of urban economy, the standard of river channel fortification is correspondingly improved, but the existing urban flood control wall only plays a role in conventional water blocking, and the runoff formed by the storm which exceeds the design standard cannot be effectively discharged in a short time, so that the river channel water level is often increased rapidly, and even a waterlogging disaster is caused. Therefore, the conventional urban flood control wall can be considered to be modified, so that the runoff in a heavy storm period can be buffered, the heavy storm runoff is temporarily stored, and peak staggering enters a river channel to relieve the pressure of the river channel. Further consideration is that it is desirable to be able to store part of the stormwater in the hope of remedying possible drought-time irrigation.
Disclosure of Invention
The utility model aims to buffer peak runoffs formed by ultra-standard storm, and provides a reconstruction scheme for urban river flood control walls, so that the flood control walls are lifted to increase the regulation function for the storm runoffs and the water storage function in dry seasons.
The utility model aims at realizing the following technical scheme:
an ecological flood control wall with a regulation function is characterized in that a water storage tank is additionally arranged on the inner side edge of an original river channel flood control wall, the bottom of one side of the water storage tank is communicated with a river channel through a check valve and a pipeline, and the other side edge of the water storage tank is externally connected with a municipal matched underground water storage structure and can be directly injected into peripheral runoff; the mounting direction of the check valve is as follows: when the river water level is higher than the water level in the water storage tank, the check valve is closed, and the river water cannot enter the water storage tank; when the water level in the water storage tank is higher than the river water level, the check valve is opened, and water in the water storage tank can flow into the river.
The water flow in the rainwater converging area is collected by the water storage tank, and rainwater can be directly connected into the rainwater pipeline or connected into some water storage facilities in a sponge city to collect rainwater. And a part of the rainwater runoffs are temporarily stored in the water storage tank, so that the peak-staggering regulation of the river flow is achieved, and the river flow and the water level at peak time are reduced.
Preferably, the check valve adopts a butterfly check valve, the valve clack of the butterfly check valve is biased with the valve seat surface, the valve clack is closed rapidly, and the quick response to the backflow of river water can be realized.
Preferably, the interior of the water storage tank is divided into two tanks, namely a water regulating tank and a water storage tank by a partition wall, the water regulating tank receives runoff and conditionally and unidirectionally discharges water to a river channel, and the water storage tank receives and stores runoff and controllably transmits the runoff water to the water regulating tank; the water regulating tank is connected with the water storage tank by a communicating pipe which can play a role of siphoning; the communicating pipe passes through a through hole or a groove arranged at a part of the partition wall, which is close to the top, and two ports of the communicating pipe are respectively fixed at the positions of the water regulating tank and the water storage tank, which are close to the bottom; the height of the residual water level of the water storage tank is indirectly determined by the highest position of the communicating pipe, the difference between the height of the communicating pipe orifice of the water storage tank and the height of the pipe top is smaller than ten meters, and the residual water level of the water storage tank is determined by the position of one end of the communicating pipe, which is relatively higher than the two end orifices of the communicating pipe.
When the ground or channel rainwater fills the water storage tank and rises to the highest position of the communicating pipe due to storm, the communicating pipe is filled with water and siphons, the water of the water storage tank is sucked to the water regulating tank until the water level of the water regulating tank is equal to the water level of the water storage tank, at the moment, if the water level of the water regulating tank is higher than the river water level, the water of the water regulating tank is discharged to a river channel through the butterfly check valve until the water of the water regulating tank and the water storage tank is discharged, and the communicating pipe stops siphoning. Then, the water storage tank continuously stores water, and the siphon action does not occur any more until the water level of the water storage tank does not reach the top of the communicating pipe. If the amount of rain is not so great, the reservoir acts purely as a water reservoir.
In general, the siphon action is generally exerted as long as the height from the suction pipe orifice of the communication pipe of the water storage tank to the top of the pipe is not more than ten meters. In the period of non-storm, the water storage tank can store water for a long time,
because the total volume of the built water storage tank is generally smaller than the natural water storage capacity of lakes and the like, the device is more suitable for daily regulation or weekly regulation of rainwater for regulating runoff, and plays an auxiliary role for higher-requirement annual regulation.
