Description
Technical field
The utility model relates to water power release floodwatering facility field, especially a kind of high flow rate runner waterproof wing masonry construction.
Background technology
Along with country is to the demand of water power clean energy resource, build a large amount of high dams, the corresponding release floodwatering facility also having built high water head for flood discharge, high flow rate.High-velocity flow turbulent fluctuation causes flow cavitation effect to form weak impact power to the concrete of flood discharging tunnel flow-passing surface, and microshock effect that is long-term, flood tide easily causes flood discharging tunnel cavitation erosion.
In addition, traditional runner flip shot can be formed and spill the water wing of the water surface after runner base plate at current, and water wing can worsen downstream flow-shape, and long-term water wing easily causes concrete surface and degrades, and becomes cavitation erosion source.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high flow rate runner waterproof wing masonry construction effectively eliminating current water wing.
The utility model solves the technical scheme that its technical problem adopts: high flow rate runner waterproof wing masonry construction, comprise the runner be made up of runner sidewall and runner base plate, also comprise the side bank that at least one is arranged at the gas well on runner sidewall and is closely set on runner sidewall, the top width on the bank top, side of described side bank is less than the bottom width of the bank bottom, side of side bank, and described gas well is communicated with runner base plate by the gas well through hole bottom gas well.
Further, gas well is for be arranged in runner sidewall in pairs, and described side bank is arranged between paired gas well.
Further, described side bank is right-angled trapezium, the hypotenuse of described side bank and water stream contacts.
Further, between described runner sidewall and runner base plate for being arranged vertically.
The beneficial effects of the utility model are: when practical application, and current, through side bank, are understood first by side bank flip shot.Top width due to the bank top, side of side bank is less than the bottom width of the bank bottom, side of side bank; the current flowing through bank top, side after flip shot first with runner sidewall contact; and the current flowing through bank bottom, side are more late with runner sidewall contact after flip shot; so namely, constituting a profile is subtriangular bank jet falling zone, side; the water wing that current produce can well cover by bank jet falling zone, described side; thus well eliminate the damage effect of water wing; ensure the good nowed forming of downstream current, and then further protect runner.The utility model design is ingenious, eliminates the excellent of water wing, is particularly useful in water power flood discharge water channel.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
High flow rate runner waterproof wing masonry construction as shown in Figure 1, Figure 2, Figure 3, Figure 4, comprise the runner 1 be made up of runner sidewall 11 and runner base plate 12, also comprise the side bank 2 that at least one is arranged at the gas well 15 on runner sidewall 11 and is closely set on runner sidewall 11, the top width (A) on the bank top, side 22 of described side bank 2 is less than the bottom width (B) of the bank bottom, side 21 of side bank 2, and described gas well 15 is communicated with runner base plate 12 by the gas well through hole 151 bottom gas well 15.
When reality uses the utility model, the effect of current is so successively: first, current flow to side Kan2Chu from flow path upstream 13, top width (A) due to bank top, side 22 is less than the bottom width (B) of bank bottom, side 21, so bank top, side water-drop point 221 and bank bottom, side water-drop point 211 be not on the straight line of vertical direction, in fact, side bank top stream distance L1 is less than bank bottom, side stream distance L2.As shown in Figure 1, if record water-drop point and the base plate flip shot water-drop point 121 of current jet after runner base plate 12, and by base plate flip shot water-drop point 121 extend base plate flip shot current border 122, water outlet wing 123 in the generation position of the water surface 3.General; runner base plate stream distance L3 is greater than stream distance L2; can ensure that all water wings 123 can all cover by the del urban conservation area S2 be made up of bank bottom, side water-drop point 211, bank top, side water-drop point 221 and bank bottom, side water-drop point subpoint 23 (bank top, side water-drop point 221 vertically with the intersection point of the water surface 3) like this, thus the generation of anti-sealing wing 123 completely.
In addition, in order to absorb outside air fully, by the technical approach protection runner base plate 12 of aeration, the utility model has organically combined the negative pressure of current, and runner sidewall 11 is provided with gas well 15.When current flow through the gas well through hole 151 bottom gas well 15, namely air can enter into runner base plate 12 place because of negative pressure, greatly reduce the cavitation erosion of current.
Further, in order to allow above-mentioned cavitation-preventive better effects if, gas well 15 can be selected to be designed to be arranged in runner sidewall 11 in pairs, and described side bank 2 is arranged at the structure between paired gas well 15.As shown in Figure 2, such structure can realize aeration effect to greatest extent, better protection runner 1.
General, in order to the construction cost of simplified side bank 2 under the prerequisite of current flip shot effect ensureing side bank 2, can select described side bank 2 to be designed to right-angled trapezium, the hypotenuse of described side bank 2 and water stream contacts.As shown in Figure 2, so not only easy to use because of the simple structure of side bank 2, there is owing to can form more regular del urban conservation area S2 effect especially that better eliminate water wing 123.Certain, for constructing of runner 1, for being arranged vertically between general preferred described runner sidewall 11 and runner base plate 12, be so also the structure runner 1 in order to economy uses.
