[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention.
[0023] Example
[0024] See also Figure 1-4 The utility model provides a technical solution: a sponge river channel structure with flood control and irrigation functions, including a river channel, a first bank channel 1 located on one side of the river channel and a second bank channel 2 located on the other side of the river channel, the first bank channel 1 and the second bank channel 2 are both buried and distributed underground, the first bank channel 1 and the second bank channel 2 evenly include a water inlet 11, a grit chamber 12, a water delivery culvert 13 and a regulating reservoir 14, the water inlet 11 is arranged in a circular structure, the water inlet 11 of the first bank channel 1 is arranged at one-half of the middle position between the river bottom and the bank on the side of the first bank channel 1, the water inlet 11 of the second bank channel 2 is arranged at two-thirds of the distance from the river bottom to the bank on the side of the second bank channel 2, the diameter of the water inlet 11 is one-third of the elevation of the river bank, and a trash rack 111 is arranged at the entrance of the water inlet 11; the grit chamber 12 is arranged in a rectangular structure, The pool 12 is connected to the water inlet 11; the regulating reservoir 14 is distributed at the upstream position of the concentrated and contiguous cultivated land, and the regulating reservoir 14 is connected to each other through the water culvert 13. The regulating reservoir 14 is internally connected with a water supply pipe for irrigation, and the end of the water supply pipe away from the regulating reservoir 14 is connected with a water supply tap. The top width of the regulating reservoir 14 is the same as the width of the embankment road. The width of the regulating reservoir 14 is 3.5m, the depth is 2m, and the length of the regulating reservoir 14 matches the river terrain; the first bank channel 1 and the second bank channel 2 are distributed near the river side with fish nest-type revetments, and concrete stone piles for fixing are evenly distributed on the fish nest-type revetments, and the distance between every two concrete stone piles is 100m; interception and drainage ditches are arranged on both sides of the river, and the interception and drainage ditches are connected to the farmland and the regulating reservoir 14; the sedimentation tank 12 is connected to the regulating reservoir 14 through the water culvert 13, and a sewage cleaning well is arranged on the top of the sedimentation tank 12.
[0025] It should be noted that, in this embodiment, the water inlets 11 on both sides of the river can adjust the elevation of the water inlets 11 on the left and right banks according to the actual terrain, and trash racks 111 need to be set at the entrances of the water inlets 11. The water inlet 11 is connected to the grit chamber 12; the grit chamber 12 is a concrete structure, and its main function is to precipitate and filter debris to prevent debris from clogging the water culvert 13; the water culvert 13 is a steel pipe, a plastic pipe or a concrete culvert, which is selected according to the actual situation. The water pipe is used to discharge flood water and connect each storage tank 14;
[0026] Furthermore, the regulating reservoir 14 is connected to the upstream and downstream water delivery culverts 13. First, it has the function of regulating floods, and second, it stores water for irrigation. The regulating reservoir 14 is generally set at the upstream of concentrated and contiguous cultivated land, and the water supply pipe is connected to the regulating reservoir 14. In the season when there is a demand for irrigation, water can be taken for irrigation in an orderly manner through the tap at the end. The regulating reservoir 14 is the same width as the road on the top of the embankment, and the length depends on the topography of the river channel;
[0027] Furthermore, concrete stone piles are mainly used to fix fish nest-type revetments and prevent scouring. Concrete stone piles are set every 100m. When the river flow rate exceeds 3m / s, the concrete stone piles need to be densely packed to 50m. Fish nest-type revetments are set on one or both sides of the river. The structure is honeycomb-shaped and is mainly buried between the normal water level and the five-year flood level to provide a habitat for aquatic organisms.
[0028] Furthermore, the water inlets 11 of the first bank channel 1 and the second bank channel 2 of the present application are respectively arranged at 1 / 2 and 2 / 3 of the river channel. When the flood reaches a flood that occurs once in five years, the flood is diverted from 1 / 2. When the flood reaches a flood that occurs once in ten years, both water inlets 11 can divert the flood. Through this flood diversion method, the flood discharge pressure of the river channel is reduced, so that the purpose of flood control standards can be achieved without widening the river channel or building too high retaining walls during river management. In addition, interception and drainage ditches are arranged on both sides of the river channel, and the interception and drainage ditches are connected to the farmland and the regulating reservoir 14. By arranging interception and drainage ditches on both sides of the river channel, the interception and drainage ditches can discharge low-polluted water from farmland surface sources into the regulating reservoir 14 for collection and reuse, and prevent low-polluted water from directly flowing into the river channel, thereby realizing the function of intercepting and reusing surface source pollution.
[0029] The utility model workflow:
[0030] When in use, during the flood season, when the flood reaches the designed water level, the left bank water inlet 11 is automatically opened, and the first bank channel 1 and the river channel jointly discharge the flood; when the flood reaches a high water level, the first bank channel 1 and the second bank channel 2 will both be opened, and the three channels will jointly discharge the flood, thereby increasing the flood discharge capacity; the first bank channel 1 and the second bank channel 2 are provided with a regulating reservoir 14 at an upstream position where there is irrigation demand. The regulating reservoir 14 has a certain volume and has the function of storing water and regulating flood volume during the flood season. During the dry season, the water stored in the regulating reservoir 14 can be used for irrigation of cultivated land along the coast, and the regulating reservoir 14 is provided at a location with higher terrain to realize gravity irrigation.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
