Abstract
The utility model discloses a multi -functional scour prevention sediment trapping bank, the wall body of making including cast -in -place reinforced concrete, the vertical section shape of wall body be right trapezoid structure, and the bottom basis of wall body be the pinion rack structure, and wall body upper portion is located the baffle that permeates water that links firmly the extension of oriented upstream side on the sloping core face of upstream side, and a plurality of holes of permeating water have perpendicularly been seted up to the edge vertical direction on the baffle that permeates water, lie in a plurality of levels that are provided with on the wall body that permeates water between baffle and riverbed unit that permeates water, the level is permeated water a plurality of rectangle levels that the unit was offered by upper and lower interval and is permeated water the hole and constitute, lieing in every level on the sloping core face of upstream side and permeating water unit department and all cover and have the geotechnological cloth that permeates water, the geotechnological cloth that permeates water passes through steel mesh frame to be fixed on the sloping core face of upstream side. The utility model discloses reduce the sediment trapping bank upstream side velocity of flow, be favorable to thin granule silt to fall to becoming silted up, bank top inflow -rate of water turbine is shared to the sediment trapping wall body for back -water height reduces before the bank, the bank offal energy of flow weakens, has consequently weakened erodeing sediment trapping low reaches riverbed.
Description
Technical field
The utility model relates to the sediment trapping bank in river controlling projects, especially relates to multi-functional protection against erosion sediment trapping bank.
Background technology
River controlling projects, especially river course building position river bed scouring downcut are obvious, and river bed needs design sediment trapping bank, to form deep trouth alluvial, raise riverbed, local, reach the protection object of poised stream bed surface.At present, going out mountain pass, the river course larger than falling both at home and abroad, is the change of steady component river bed, commonly uses under sediment trapping bank stops the imbalance of river course bed load and lets out, at the bottom of the poised river keeping a certain elevation.Sediment trapping bank adopts straight wall type structure usually, and river bed is imbedded in bottom, hangs part and blocks depositing in water sand to raise riverbed, local, similar overfall dam operating principle.Above-mentioned straight wall type structure sediment trapping bank structure is simple, easily construction, applied widely.Material can adopt concrete, stone-laying, loose jackstone cage etc.But in the application, this straight wall type structure has fine grained fall to becoming silted up slow, downstream easily to occur that current concentrate punching wash in a pan and cause headcut scour, destroys ground at the bottom of bank, causes the situations such as sediment trapping bank unstable failure.Engineering also there is the basis of aimed wall take consolidation process, but do not utilize the structural shape that sediment trapping bank self structure cuts down water energy, quickening falls to becoming silted up, slow down current incision.
Summary of the invention
The utility model object is to provide a kind of multi-functional protection against erosion sediment trapping bank.
For achieving the above object, the utility model takes following technical proposals:
Multi-functional protection against erosion sediment trapping bank described in the utility model, comprise the body of wall that cast-in-situ steel reinforced concrete is made, the longitudinal section shape of described body of wall is ladder structure of right angle, the base foundation of body of wall is toothed plate structure, the sloping core face that body of wall top is positioned at upstream side is fixed with the permeable baffle plate that upstream side extends, described permeable baffle plate vertically offers multiple vertical permeable hole; Body of wall between permeable baffle plate and riverbed is provided with the permeable unit of multiple level, multiple rectangular horizontal permeable holes that the permeable unit of described level is offered by upper and lower interval are formed; The sloping core face of upstream side is positioned at each level permeable unit place and is all coated with permeable geotextiles, described permeable geotextiles is fixed on the sloping core face of upstream side by steel wire net rack.
The height of described rectangular horizontal permeable hole is 3 centimetres, and width is 30 centimetres, and upper and lower adjacent rectangular horizontal permeable hole center square is 15 centimetres.
The utility model, compared with existing sediment trapping bank, has the following advantages:
1, reduce sediment trapping bank upstream side flow velocity, be conducive to fine sediment and fall to becoming silted up;
2, sediment trapping body of wall shares bank top inflow-rate of water turbine, and before making bank, under height of swell reduction, bank, water flow dynamic energy weakens, and therefore reduces washing away sediment trapping underwater bed;
3, the current crossing bank are horizontal forward, drop and do not play mutual blending effect in the same way, weaken bank top current downstream rate with Kan Ding, and protection river bed is from scour;
4, the longitudinal section shape of body of wall is set to right-angled trapezium permeable structure, and body of wall bears water flow impact pressure and reduces, favourable monolithic stability;
5, before permeable baffle plate blocks bank, silt crosses Kan Ding, and reduces the Water And Earth Pressures of body of wall.

Detailed description of the invention
As Figure 1-3, multi-functional protection against erosion sediment trapping bank described in the utility model, comprise the body of wall 1 that cast-in-situ steel reinforced concrete is made, the longitudinal section shape of body of wall 1 is ladder structure of right angle, the base foundation of body of wall 1 is tooth plate 2 structure, the sloping core face 3 that body of wall 1 top is positioned at upstream side is fixed with the permeable baffle plate 4 of upstream side horizontal-extending, permeable baffle plate 4 vertically offers multiple vertical permeable hole 5, the layout quantity of vertical permeable hole 5 and spacing depending on concrete punching dark and building arrange and determine; Body of wall 1 between permeable baffle plate 4 and riverbed 6 is provided with the permeable unit of multiple level, the quantity of the permeable cell layout of level is comprehensively determined according to bed load particle diameter and inflow-rate of water turbine; Multiple rectangular horizontal permeable holes 7 that the permeable unit of level is offered by upper and lower interval are formed, and the height of rectangular horizontal permeable hole 7 is 3 centimetres, and width is 30 centimetres, and upper and lower adjacent rectangular horizontal permeable hole 7 center square is 15 centimetres; As shown in Figure 2, the sloping core face 3 of upstream side is positioned at each level permeable unit place and is all coated with permeable geotextiles 8, permeable geotextiles 8 is fixed on the sloping core face 3 of upstream side by steel wire net rack 9.
Sediment trapping bank of the present utility model is permeable, shares cross-section of river certain flow, and current basic flow pattern before maintenance bank, section flow rate of water flow reduces, and is conducive to falling silt.Cross bank top discharge per unit width to reduce, the kinetic energy of current reduces, and weakens washing away of bank underwater bed.Cross sediment trapping bank level permeable unit current and cross the descending current in bank top and interact, cut down current incision kinetic energy, have protective effect to riverbed at the bottom of bank.When depositing to upper strata, current top-lashed action bank body is up, and larger gravel of may carrying under one's arms jumps to downstream, the filtration of level permeable baffle plate 4.The permeable baffle plate 4 of level and base foundation tooth plate 2, from structure loading characteristic aspect, enhance overall anti-to incline, stability against sliding.
