Abstract
The utility model discloses a kind of Rib Reinforced Bifurcation Pipes, including tube body, the Rib Reinforced being arranged on tube body, rigid supporting rod are fixed between the two ends of Rib Reinforced, supporting rod is sealed with tube body intersection.The utility model solve thes problems, such as trouble crotch and intersection intersection stress concentration, and the peak stress of bifurcated pipe structure is greatly reduced, and then reduces the pipe thickness of entire bifurcated pipe, saves rolled steel dosage.
Description
Technical field
The utility model belongs to hydraulic and hydroelectric engineering field, and in particular to a kind of Rib Reinforced Bifurcation Pipe.
Background technology
Penstock is the component of water conveyance structure in hydraulic and hydroelectric engineering, and bifurcated pipe is normally at the end of pressure pipeline
End, internal water pressure is larger, and structure stress situation and HYDRODYNAMIC CONDITION RELATING TO are complicated, mainly include three beam bifurcated pipes, Rib Reinforced Bifurcation Pipe, ball-type
Bifurcated pipe, without the structural shapes such as beam bifurcated pipe and hem reinforced branch pipe, wherein Escher-Wyss wyepiece has that flow-shape is good, the loss of flood peak
The features such as small, stress is clearly, cavern excavation section is small, bearing installation is easy, at home and abroad large and medium-sized routine and water-storage are electric
It stands and is widely used in underground buried tube.
As shown in Figure 1, 2, Rib Reinforced Bifurcation Pipe includes tube body 1, Rib Reinforced 2, and tube body 1 includes supervisor 11 and branch pipe 12.Crescent moon
Rib bifurcated pipe belongs to complex space combining structure, and force-bearing situation is complicated, when carrying out bifurcated pipe design, the hydraulics of bifurcated pipe, structure by
Requirement in terms of power and fabrication and installation has certain conflict, it is difficult to meet simultaneously.For HYDRODYNAMIC CONDITION RELATING TO, it is desirable that branch pipe has one
Fixed cone angle and smaller fork angle, but cone angle is bigger, fork angle is smaller, and more unfavorable to structure stress, difficulty of construction is bigger.
From figure 3, it can be seen that there are stress concentration at bifurcated pipe intersection vertex A, in obtuse angle area stringcourse deflection angle C, D regions, branch pipe waist
The controlling stress value of stringcourse turnover angular zone is big at line deflection angle F, G regions and maximum gauge.
Under prior art conditions, bifurcated pipe design is aided with certain model test still using traditional experience design method
To complete.During design, often according to the stress value calculated, to design tube thickness, make it in the strength range of safety, due to
These stress values are larger, and the bifurcated pipe for often leading to design is thicker.Therefore for bifurcated pipe, especially head, the larger trouble of predominant tube diameter
Pipe carries out build and dimensionally-optimised design, in economy and the security important in inhibiting of engineering.
Utility model content
In view of the above-mentioned problems, the utility model, which is intended to provide one kind, can alleviate stress concentration, reduce the moon of controlling stress
Tooth rib bifurcated pipe.
The technical solution that the utility model solves the problems, such as is：A kind of Rib Reinforced Bifurcation Pipe including tube body, is arranged on tube body
Rib Reinforced, is fixed with rigid supporting rod between the two ends of Rib Reinforced, and supporting rod is sealed with tube body intersection.
By increasing supporting bar structure, the stress at bifurcated pipe intersection vertex A can be disperseed, effectively alleviated
Stress concentration is computed can also significantly lowering obtuse angle area stringcourse deflection angle C, D regions, branch pipe stringcourse deflection angle F, G
The controlling stress value of stringcourse turnover angular zone at region and maximum gauge.
To increase intensity and better seal, the supporting rod is with tube body intersection using welding with reinforcement plate, the reinforcement
Plate and tube body material identical.
Preferably, the supporting rod includes fusiformis mobile jib, the socket cap positioned at fusiformis mobile jib both ends, the mobile jib and cylinder
It is first body formed.The inner cavity of tube body is placed in using fusiformis mobile jib so that influence of the component newly increased to flow-shape is minimum, adopts
It is more convenient in order to weld with the both ends of socket cap.
Further, the support rod outer surface is equipped with corrosion-inhibiting coating.
The utility model solve thes problems, such as trouble crotch and intersection intersection stress concentration, and bifurcated pipe knot is greatly reduced
The peak stress of structure, and then the pipe thickness of entire bifurcated pipe is reduced, save rolled steel dosage.

Specific embodiment
As shown in Figures 4 and 5, a kind of Rib Reinforced Bifurcation Pipe, including tube body 1, the Rib Reinforced being arranged on tube body 12.In Rib Reinforced
Rigid supporting rod 3 is fixed between 2 two ends.3 outer surface of supporting rod is equipped with corrosion-inhibiting coating.
The supporting rod 3 is welded with 1 intersection of tube body using stiffening plate 4, the stiffening plate 4 and 1 material identical of tube body.
There are many forms of supporting rod 3, in order to enable the influence to flow-shape is reduced to minimum, a kind of specific structure
Form is, as shown in fig. 6, the supporting rod 3 includes fusiformis mobile jib 31, the socket cap 32 positioned at 31 both ends of fusiformis mobile jib, it is described
Mobile jib 31 is integrally formed with socket cap 32.
During construction, in the trouble crotch intersection point of intersection perforate of tube body 1, supporting rod 3 is placed afterwards, supporting rod 3 is managed through entire
1 top and bottom of body.Tube body, supporting rod 3,2 two ends of Rib Reinforced are welded as overall structure by aperture perimeters with stiffening plate 4.
