Detailed description of the invention
Describe performance of the present invention in detail below in conjunction with accompanying drawing, but they do not form limitation of the invention, only for example.Make advantage of the present invention more know and easily understand by explanation simultaneously.
Consult accompanying drawing known: novel fish channel structure, comprise fish pass sidewall 1 and contraction section 2, described contraction section 2 is arranged on fish pass sidewall 1, and fish pass 3 is divided into chamber, multiple spaced apart pond 4, described contraction section 2 comprises long contraction section 21 and short contraction section 22, and long contraction section 21 is positioned opposite with short contraction section 22, between long contraction section 21 and short contraction section 22, is fish perps 5, between adjacent pool chamber 4, passed through fish perps 5 and be communicated with, described long contraction section 21 is interlaced arrangement in fish pass 3 both sides.
Fish pass or channel 3 are concrete rectangular or trapezoidal flume, and the present invention is equidistant in fish pass or unequal-interval arranges the contraction section 2 of length limit interlaced arrangement, and then forms chamber, pond 4, then arranges 3 groups of pier studs that block water at interior interval, chamber, pond 4.
When real work, 4 middle parts, chamber, pond arrange first group of pier stud 61 that blocks water, first group of pier stud 61 that blocks water crossed fish perps 5 0.4～0.6Lm places, center apart from upper level, first group of pier stud 61 that blocks water can carry out energy dissipating to current, and mobile water body is spread to both sides, the flow intensity that makes chamber, higher level pond flow into chamber, pond at the corresponding levels is reduced for the first time.First group of pier stud 61 that blocks water comprises first pier stud a, second pier stud b and the 3rd pier stud c that blocks water that blocks water that blocks water.
Flow-shape after reducing according to water body diffusion, flow velocity, second group of pier stud 62 that blocks water is set in 4 middle and lower parts, chamber, pond, the height of pier stud is determined by crossing fingerling class, second group of pier stud 62 that blocks water is arranged on first group of pier stud 61 downstream that block water, and being positioned at the water inlet upstream of fish perps 5, second group of pier stud 62 that blocks water can make current form the layering current of different in flow rate in space.Second group of pier stud 62 that blocks water comprises the 4th pier stud d, the 5th pier stud e, the 6th pier stud f and the 7th pier stud g that blocks water that blocks water that blocks water that blocks water.
Crossing, fish perps 5 is interior arranges the 3rd group of pier stud 63 that blocks water, the 3rd group of pier stud 63 that blocks water crossed the water inlet of fish perps 5 and crossing between the delivery port of fish perps 5, current form the flow field of big or small subregion when by contraction section, trace back with the fish that meet different grams of stream abilities.The 3rd group of pier stud 63 that blocks water comprises the 8th pier stud h, the 9th pier stud i and the tenth pier stud j that blocks water that blocks water that blocks water
The layout of the above-mentioned pier stud that blocks water need be determined according to the flow condition in channel.The above-mentioned pier stud that blocks water can adopt stone column, grout the structural shape such as structure, ecological cage.First group of pier stud 61 that blocks water can be stone column, grout the one in structure, ecological basket structure, second group of pier stud 62 that blocks water can be stone column, grout the one in structure, ecological basket structure, and the 3rd group of pier stud 63 that blocks water can be stone column, grout the one in structure, ecological basket structure.
Operating principle of the present invention is: current are after upper level is crossed fish perps 5 and to be flowed out, and through the obstruct of first group of pier stud 61 that blocks water, current disperse, flow velocity reduces; Block water after pier stud 62 through second group, current will further disperse to slow down, and form layering current; The 3rd group of pier stud 63 that blocks water is arranged on contraction section, and current block water after pier stud 63 through the 3rd group, and flow field is subzone again, and part flow rate of water flow meets the most weak fish of Burden-Swimming Ability of KM and traces back requirement.
Taking water (flow) direction as with reference to and with reference to figure 2, the arrangement of the pier stud that blocks water is as following table:
Table 1
In upper table, when the arrangement of the pier stud that blocks water is shown in following table time, working effect of the present invention is more obvious:
Table 2
The described first center that blocks water pier stud a is crossed at upper level on the extended line of fish perps 5 center lines, and the first vertical distance blocking water between pier stud a and the long contraction section 21 of upper level center is 0.4～0.6Lm.
As shown in Figure 2, the tenth pier stud j that blocks water should be arranged on the water outlet of fish perps 5.The ratio of the length B2 of the length B1 of long contraction section 21 and short contraction section 22 is 2.5～6.5, and the length B2 sum of the length B1 of long contraction section 21 and short contraction section 22 is 0.10～0.50Lm.
In practical work process, when the first height and second that blocks water pier stud a blocks water the height of the pier stud b depth of water indoor with pond when identical, the working effect of first group of pier stud 61 that blocks water is best, staff need to be according to first the block water streamflow regime in pier stud b downstream of pier stud a and second that blocks water, determine whether to arrange the 3rd pier stud c that blocks water, and determine the 3rd height that blocks water pier stud c according to crossing fingerling class and size.
Show through long-term practice, when the 6th height that blocks water pier stud f is 1/2 of chamber, the pond depth of water, and the block water height of pier stud e and the 7th height that blocks water pier stud g of the 4th height, the 5th that blocks water pier stud d is 1/3 o'clock of chamber, the pond depth of water, and second group of pier stud 62 that blocks water reaches best working effect.
Show through long-term practice, when the block water height of pier stud i of the 8th height and the 9th that blocks water pier stud h is 1/3 of chamber, the pond depth of water, and the tenth height that blocks water pier stud j is 1/2 o'clock of chamber, the pond depth of water, and the 3rd group of pier stud 63 that blocks water reaches best working effect.Staff need to be according to the 8th the block water streamflow regime in pier stud i downstream of pier stud h and the 9th that blocks water, determine whether to arrange the tenth pier stud j that blocks water, and determine the tenth height that blocks water pier stud j according to crossing fingerling class and size, in real work, the tenth pier stud j that blocks water should be arranged on the water outlet of fish perps 5.The present invention solves the new tool that straddling fish stocks are traced back by barrage building, it is compared with external by-pass (imitative nature fish pass), the head that the present invention adapts to is higher, in can be used as, the first-selected structural shape of low water head barrage building fish pass structure.Its advantage is to have the plane similar with by-pass pattern and space flow-shape, can pass through multiple fish, also meets the dam demand of crossing of juvenile fish and prelarva; Meanwhile, floor space of the present invention is less, is better than technically and economically by-pass pattern.
Other unaccounted part all belongs to prior art.
