As shown in Figure 1, 2, the ecological flow buret layout pattern of concrete dam of the present utility model, dam body 1 is provided with discharge orifice runner 2; What discharge orifice runner 2 downstreams had length that close bank slope arranges lets out groove 4; The import 5 of ecological flow buret 3 is arranged on the concrete dam body 1 on the sidewall in the discharge orifice runner 2 in discharge orifice emergency repair door 8 downstreams that arrange; The outlet 6 of ecological flow buret 3 is arranged in outer the letting out on the sidewall in the groove 4 of arranging of discharge orifice service gate 9 downstream dam bodys, and the control gate valve 10 of ecological flow buret is arranged at the outer downstream of dam body.
Described ecological flow buret 3 be (broken line type, the import 5 of ecological flow buret and discharge orifice runner 2 obliques, the outlet 6 of ecological flow buret with let out groove 4 obliques.
Be positioned at that the groove 4 of letting out of certain limits is provided with steel lining 7 near the outlet 6 of near discharge orifice runner 2 inwalls of the certain limits import 5 of ecological flow buret and ecological flow buret, the smooth welding of ecological flow steel pipe that steel lining 7 is interior with letting out groove 4 with being embedded in concrete dam body 1.
Brushing has the coating of anti-impact mill, anti-corrosion on the described steel lining 7.
The import 5 of described ecological flow buret is arranged in the discharge orifice of low elevation in the dam body discharge orifice.
Described concrete dam is gravity dam or arch dam, and the dam body dam material is normal concrete or roller compacted concrete.
Described ecological flow buret 3 is steel pipe.
Specifically, dam body 1 is provided with discharge orifice runner 2; What discharge orifice runner 2 downstreams had length that close bank slope arranges lets out groove 4; The pattern that ecological flow buret 3 is arranged be (broken line type, its import 5 shares with discharge orifice runner 2, is arranged on the interior sidewall of the runner in discharge orifice emergency repair door 8 downstreams that arrange on the concrete dam body 1; The outlet 6 of the ecological flow buret 3 in downstream shares with the outer groove 4 of letting out that arranges of discharge orifice dam body, and outlet is arranged in outer the letting out on the sidewall in the groove 4 of arranging of discharge orifice service gate 9 downstream dam bodys; Import 5 with outlet 6 all with discharge orifice runner 2 or let out groove 4 obliques.Be positioned at ecological flow buret import 5 or export near the discharge orifice runner 2 of certain limits 6 or let out on the groove 4 steel lining 7 need be set, and can on steel lining 7, brush the coating with performances such as anti-impact mill, anti-corrosions; Control gate valve 10 facilities such as grade of ecological flow buret are placed in the downstream outside the dam body 1.
Be elaborated below in conjunction with specific embodiment:
Certain medium hydropower station engineering, dam are rolled concrete arch dam, maximum height of dam 107m, dam crest arc length 160m.Adopt the arrangement of dam body flood discharge, the husky building of flood discharge row is made up of three weir meter holes, two flood discharge mesopores, the husky hole of row.Weir meter hole weir crest elevation 1062.50m, aperture width 10.0m, the flip trajectory bucket mode is adopted in energy dissipating; Flood discharge sand surfing mesopore import floor elevation is 1020.00m, port size be 5m * 6.5m(wide * height), adopt the flip trajectory bucket mode; Arranging husky hole import floor elevation is 1025.00m, port size be 2 * 4m(wide * height).Wherein arrange and connect the length of arranging on the right bank bank under the husky hole and let out groove, export and be special-shaped bucket lip, adopt the flip trajectory bucket mode.
For satisfying the requirement of releasing of dam to the ecological flow of factory building section, be provided with the ecological flow buret.Need let out ecological flow down dry season and be about 7.2m
3/ s.As Fig. 1, shown in 2, in the runner 2 in the husky hole of ecological flow buret 3 rows of being arranged in, be that an internal diameter is D800mm, wall thickness 10mm, the steel pipe of the about 29m of length, on the right side wall of ecological flow buret import 5 rows of being arranged in husky hole Emergency Gate 8 rear portion runners 2, adopt the pipe laying mode to pass dam body 1 on runner 2 right sides in the husky hole of row, in dam body 1 downstream and let out and be provided with 1023.7m elevation fill concrete platform between the groove 4, connect control gate valve 10 at this section ecological flow buret 3 in the exposed conduit mode, control downstream, the husky hole of ecological flow buret 3 rows of passing, gate valve 10 downstream let out groove 4 abutment walls, the stream that will descend to sluice inserts to be arranged husky hole and lets out the groove section and enter downstream river course.
Ecological flow buret import and export section is respectively 45 °, 60 ° with the husky axially bored line angle of cut of row, for preventing the water sand drift speed that the bend loss current are bigger and cavitating to arranging abrasion and the influence of husky orifice flow road structure, in the husky hole 2 of row and ecological flow buret 3 import and export sections handing-over position certain limit, be provided with the steel lining 7 of thickness 20mm, and brush the coating with performances such as anti-impact mill, anti-corrosions.
Layout pattern described in the utility model is particularly useful for following situation: (1) arranges the ecological flow tubular structure at the high dam dam body; (2) river valley is narrow, and the aperture arranges that width is limited; (3) arch dam bodily form degree of hanging by the feet is bigger, needs to arrange long outer outstanding structure; (4) the discharge orifice downstream has the length that close bank slope arranges and lets out groove.The utility model is different from the method to set up of ecological flow tubular structure routine on the concrete dam body, the import of ecological flow buret, outlet and discharge orifice are shared, import is arranged on discharge orifice emergency repair passage downstream side, facilities such as outer outstanding structure that conventional need arrange in the dam body upstream and gate have been cancelled, namely be beneficial to maintenance from now on, also reduced the setting of the outer attached structure of dam body; Outlet shares with the outer groove of letting out that arranges of discharge orifice dam body, solved the problem that the stream that time sluices is connected with downstream river course preferably.
Above-described embodiment only is used for explanation technological thought of the present utility model and characteristics, its purpose is to make those skilled in the art can understand content of the present utility model and implements according to this, can not only limit claim of the present utility model with present embodiment, be equal variation or the modification that spirit that all the utility model disclose is done, still drop in the claim of the present utility model.
