Abstract
The utility model discloses the permeable guide wall structure of a kind of porous, comprise the guide wall body of building in barrage building downstream; Guide wall body is divided into solid wall section and permeable wall section from head end to end, the guide wall body of permeable wall section offers from bottom to top arranges permeable hole more, permeable wall section is initiated with thin porose area, hypomere is close porose area, the pitch-row that permeable hole often arranges reduces gradually along Parallel to the flow direction, permeable hole line-spacing is evenly arranged, the axis of each permeable hole inside guide wall body to outside towards Parallel to the flow direction planar tilt.The utility model advantage is to utilize permeable hole sideway diversion, makes inner lead outside guide wall body produce gradual change current water, changes the boundary environment that guide wall body tip current spread suddenly.Main flow area and the asymptotic change of inner lead water kinetic energy, the diffusion of gradual change current compressing main flow, thus reach guide wall body tip lateral current and convolution eddy current disappears or the object that weakens.
Description
Technical field
The utility model relates to barrage building downstream guide wall, especially relates to the permeable guide wall structure of porous.
Background technology
Water conservancy and hydropower barrage building engineering office opens the problem that earial drainage is connected with the natural river course water surface, comprises that anti-transverse direction is repulsed or subdue the enemy, eddy current, punching are washed in a pan, energy dissipating etc., is paid close attention to by domestic and international correlative study scholar and project planner always.Usually, the earial drainage district outlet side in building downstream arranges guide wall, facilitates the good transportation of current, lets out under guiding current, current is evenly spread gradually unlikelyly to reflux, whirlpool or crossing current, in order to avoid rush pelican bed, bank slope.The reasonability of guide wall design is for the safe operation, economic most important guaranteeing engineering.At present, barrage building downstream guide wall end dispersion of flow, substantially without control measure, goes out that wall current are repulsed or subdue the enemy, inner lead convolution happens occasionally, and has adverse effect in various degree to stabilization of river bed and building safety.
Summary of the invention
The utility model object is to provide a kind of porous permeable guide wall structure, realizes dynamic pool to inner lead gradual transition.
For achieving the above object, the utility model takes following technical proposals:
The permeable guide wall structure of porous described in the utility model, comprises the guide wall body of building in barrage building downstream; Described guide wall body is divided into solid wall section and permeable wall section from head end to end, the guide wall body of described permeable wall section offers from bottom to top arranges permeable hole more, permeable wall section is initiated with thin porose area, hypomere is close porose area, the pitch-row that permeable hole often arranges reduces gradually along Parallel to the flow direction, permeable hole line-spacing is evenly arranged, the axis of each permeable hole inside guide wall body to outside towards Parallel to the flow direction planar tilt.
That arranges permeable hole described goes up a ranking most in the middle part of permeable wall section more.
The utility model advantage is to be opened in the many rows permeable hole on described permeable wall section body of wall from bottom to top, and the pitch-row of every row permeable hole is reduced to arrange along Parallel to the flow direction gradually, utilize permeable hole sideway diversion, make inner lead outside guide wall body produce gradual change current water, change the boundary environment that guide wall body tip current spread suddenly.Main flow area and the asymptotic change of inner lead water kinetic energy, the diffusion of gradual change current compressing main flow, thus reach guide wall body tip lateral current and convolution eddy current disappears or the object that weakens.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Detailed description of the invention
As shown in Figure 1, 2, the permeable guide wall structure of porous described in the utility model, comprises the guide wall body of building in barrage building downstream, described guide wall body is divided into solid wall section 1 and permeable wall section 2 from head end to end, the guide wall body of described permeable wall section 2 offers many row's permeable holes 3 from bottom to top, that arranges permeable hole 3 described goes up a ranking most in the middle part of the body of wall of permeable wall section 2 more, often the pitch-row of row permeable hole 6 reduces gradually along Parallel to the flow direction, the axis 5 of each permeable hole 4 inside guide wall body to outside towards Parallel to the flow direction planar tilt, the pore size of permeable hole 4 and determining depending on letdown flow and riverbed natural width to the horizontal tilt angle of Parallel to the flow direction, in conjunction with concrete engineering, optimal parameter can be obtained by hydraulic model test.
