Detailed description of the invention
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figures 1 to 7, a kind of flood-releasing energy dissipation and anti-scour facility structure described in the utility model, comprise that abnormal shape chooses bank 1 and energy dissipating merit 2, the bank base plate 101 of choosing that described abnormal shape is chosen bank 1 is skew wall warp surface, the leftwall leading portion 102 that abnormal shape is chosen bank 1 is straightway, the leftwall back segment 103 that abnormal shape is chosen bank 1 is arc, the RightWall 104 that abnormal shape is chosen bank 1 is straightway, described energy dissipater 2 forms by lay the polyhedron concrete block 201 that one deck connects mutually on Riverbed excavation foundation, described polyhedron concrete block 201 bottoms connect successively by some bottoms connecting ring 202.Adopt the technical program, thereby energy dissipater 2 can make current overturn, stretch, mutually collide and reach effective energy dissipating aloft; Owing to choosing from abnormal shape bank 1 afterbody, lay interconnective polyhedron concrete block 201 as energy dissipater 2 in bottom, excavation riverbed, can effectively reduce washing away riverbed, can strengthen the blending friction between current simultaneously, increase effect of energy dissipation, reduce flow velocity, not only met energy dissipating erosion control but also constructability.
The straightway of the arc of described leftwall back segment 103 and leftwall leading portion 102 is tangent and in smoothing junction.
Described skew wall warp surface is formed by the anti-segmental arc face of cylinder of a change horizontal wall inscription ratio, and horizontal wall inscription moves towards from left to right, right low left high.
Described horizontal wall inscription is than tapering to 1 from 0.
The width of described polyhedron concrete block 201 and be highly 3m.As shown in Figure 5, polyhedron concrete block 201 described in the utility model is stage body shape.
As shown in Figure 6, described bottom connecting ring 202 is positioned on steel wire axis 203.So bottom connecting ring 202 is on same straight line, and this straight line and steel wire axis 203 conllinear.
Described energy dissipating section chief 28.5m, curve is led wall, bottom warp face will be changed the direction of a stream of water it is chosen into downstream river course, avoids opposite jet flow opposite bank side slope.
For the flood discharge outlet that is difficult to return groove, adopt abnormity described in the utility model to choose bank 1, can obtain and return preferably groove and effect of energy dissipation.For example river, the pillow dam ditch water discharge hole outlet axis opposite bank that liquidates, return groove difficulty large, adopt abnormal shape to choose bank 1 according to landform geological conditions and flood discharging arrangement, choose bank base plate 101 for skew wall warp surface, skew wall warp surface is that the anti-segmental arc face of cylinder distortion of a change horizontal wall inscription ratio comes, leading wall is arc, has reached the desirable groove effect of returning.Simultaneously dark for absorption basin place covering layer, be difficult to arrange that protection-apron, movable bed can not meet again the problem of energy dissipating requirement, on Riverbed excavation foundation, lay the polyhedron concrete block that one deck is connected mutually, polyhedron width, be highly 3 meters, due to mutual series connection, increase the friction to current, made current more disorderly, reached usefulness effect; Meanwhile, mutually the polyhedron of series connection has erosion control effect to current, fluidised form in absorption basin, washes away situation and effect of energy dissipation has all obtained larger improvement, energy dissipating erosion control successful and convenient construction.
