Example Embodiment
[0042]Example 1
[0043]This example provides a deep groove and application of a curved dam as a northern arc-shaped dam, a deep groove as a main groove and a north slot.
[0044]The above-mentioned deep trough-curved dam is constructed in the estuary-curved area of the lake stream 3 in my country, the river network area. The curved dam includes the Northern Arc-shaped dam 6; the deep groove is the main groove 12 and the north slot 4; U-dating 10 Located between the North Arc Scorpion Dam 6 and the river bank, the northern slot 4 is located in the south side of the Northern Arc-shaped dam, the main groove 12; planting aquatic plants on the dams.
[0045]In the North Danhe, the water flow is entered into the road, the water flow is shocked on the shoreline, settled with sediment, and the sediment of water pollution, sediment and pollutant is in the river, and the main ecological issues of this area are in this area. Main groove - the deep trench of the North Slot - the Northern Arc Scorpion...
Example Embodiment
[0053]Example 2
[0054]This embodiment provides a deep trench and application of the arc dam, the northern arc dam, deep groove, the south slot and the northern slot.
[0055]Squares - curved dams in the estuary 7 of the River 3 of my country, River Network Area, have a deep trench - curved dam, including the arc dam 9, Northern Arc-shaped dam 6, deep groove includes main groove 12, south slot 8 and North Save 4. The U-Dam 10 is located in the Northern Arc Scorpion Dam, the South Arc Dam and the river bank, outside the north slot and the south slot; the sub-dam 11 is located between the south, the Northern Arc-shaped dam; the main groove 12; planting aquatic in the dam plant.
[0056]Main groove 12-South Sand 8-North Save 4-Non-Arc-shaped dam 9-Northern Dam 6 Structure, South, North Arc Dam and shore line deviation angle at about 55 ~ 60 °, curved dam body bend away from Shoreline, the arc parameter is: length 940m, width 37m, top elevation 3M, lower than normal water level 0.16m; deep groo...

Abstract
The invention belongs to the field of hydraulic structures, and discloses a deep groove-arc dam. The deep groove-arc dam is characterized in that arc dams and deep grooves are taken as core structures, and are organically combined with U-shaped dams, submerged dams and aquatic plants; the deep groove-arc dam is applied to a lake-entering estuary area; the arc dams are mainly distributed on the south side and/or the north side of an estuary, and can play roles in restraining and guiding water flow, scouring sediment and keeping the water depth of a lake outlet; the deep grooves comprise the main grooves distributed in the middle of the estuary and south grooves and/or north grooves distributed in the south side and the north side of the estuary, and play roles in promoting the sedimentation of the sediment and purifying water; the U-shaped dams and the submerged dams are distributed in a staggered mode, and play a role in intercepting the sediment; and the aquatic plants are planted on the arc-shaped dams, the U-shaped dams and the submerged dams, can purify the water, and play important roles in diverting and guiding water flow, promoting the sedimentation of suspended solids in water and intercepting pollutants. The deep groove-arc dam has the advantages of being easy to operate, low in construction cost, environment-friendly and the like, and can generate remarkable economic benefits and social benefits in the technical field of river diversion and the field of water purification.
Description
technical field [0001] The invention belongs to the field of hydraulic structures, and in particular relates to a deep groove-arc dam structure, which is applied to the diversion and purification process of rivers entering lakes, and can play the role of diversion and promotion of sinking and purification. Background technique [0002] Due to the large flow of water in the estuary area, the water flow carries a large amount of sediment, which is easy to form an alluvial fan. At the same time, the river water carries pollutants such as nitrogen and phosphorus, which has a great impact on the water environment of the estuary area and receiving water bodies. Therefore, it is necessary to set up diversion and sedimentation promotion purification facilities in the estuary area. [0003] At present, my country has not yet formed a complete estuary diversion to promote sedimentation purification technology system. The existing diversion dams are mainly used to change the flow veloc...
