Abstract
The utility model relates to a permeable member which has the functions of speed reduction, flow guide and energy dissipation and is used for prevention of flood and flushing and protection of river banks. The four-face six-side frame of the utility model is formed by mutually connecting six frame bars with the same or similar length. When the utility model is used, a plurality of groups of frames which are bundled into series are thrown into offshore water to form various forms of piles, and the flowing state of water is changed when water flows through the piles of the frame. The scouring to bank slopes, which is caused by the fluid, is changed into non-scouring or siltation, and therefore, the purposes of protecting banks, stabilizing slope feet, reducing the depth of scoured pits, making beaches near slit, controlling and guiding the river tendency, etc., can be achieved.
Description
The utility model belongs to the hydraulic engineering technical field, relates to a kind of shore protection flood control checking motion, its product can be widely used in river, river, lake, storehouse and seashore, harbour flood control, speedily carry out rescue work, block up, the aspects such as erosion control of dredging waterway and Bridge Pier.
River dike is its middle and lower reaches dyke lifeline that is people across the Straits particularly, owing to reasons such as river course instabilities, bar very easily takes place in flood season and collapses nest and collapse phenomenon in rivers middle and lower reaches one band embankment, and serious threat flood control dam safety threatens the safety and the development and national economy of people's lives and properties.For this reason, rivers shore protection flood protection works have very been paid attention to since the human own history always, and formed multiple shore protection technology and shore protection form in practice.
Rivers middle and lower reaches shore protection flood control erosion control engineering then can be divided into entity anti-impact shore protection by the classification of shore protection mechanism and slow down not towards shore protection.Entity anti-impact shore protection is to utilize the entity impact resistant material to withstand current scour or force flow direction-changing with the protection bank slope, and for example general jackstone, stone-laying shore protection, groynes or rock head, mattress sinking, geotechnique's pillow, steel bar concrete mould bag mode shore protection etc. all belong to this type of.But the entity shore protection often exists the stable problem that basic scour influences bank protection work self, and riprap protection for example, current are met piece stone water flowing value mv when being obstructed
2Instantaneously be kept to zero, by the power conversion rule, it promptly is transformed into other energy, forms spiral flow, backflow etc., and scour stone basis forms the huge hole that dashes, and causes piece stone to roll, cave in, so that the unstability of bank protection work own; Groynes also is so, makes flow direction-changing by force with groynes, and current respectively form a backflow before and after groynes, form spiral flow at abutment, spiral flow constantly screws out loss with basic sandstone, and scour basis forms huge dash hole, the unstability or the destruction that cause the unstability of self and cause bank protection work.Slowing down not towards shore protection is to utilize permeable structure such as Ma Quan, hang things such as willow, steel bar concrete network row the river course is renovated, change flow-shape, reduce the bank flow velocity, the brunt that changes the bank is below the non-scouring velocity even drops to the effect that can fall to becoming silted up, to protect the riverbank, to hold bank slope.Though it is not better towards technology shore protection effect to slow down, the basic subaqueous construction of its used structure is comparatively complicated, needs enough buried depths can keep the basis and is not washed away and the unlikely destruction of framework; In addition, permeable component adaptation deformation ability such as Ma Quan is relatively poor, in case be subjected to displacement ineffective effect even if meet current scour.
The purpose of this utility model is to overcome the existing in prior technology defective, so provide a kind of rational in infrastructure, novel, construction cost is low, easy to use and shore protection flood control erosion control four sides hexagon water-permeable frame with fine shore protection effect.
The technology for achieving the above object and solution that designs is such: the shore protection flood control erosion control four sides hexagon water-permeable frame that is provided is a kind of four sides hexahedron framework that is interconnected to constitute by six roots of sensation equal in length or close frame bar; during use; several frameworks are tied up string and many framings string is jettisoninged in the offshore water; be built into various forms of accumulation bodies just as the rock head; because the hexahedron framework moulding of this four sides has homeostasis; permeable; be fit to the characteristics that any landform changes; current by framework after fluidised form change; flow velocity is also disperseed and is reduced to less than non-scouring velocity; and the process that reduces flow velocity is gradual change; therefore can not produce the disturbance scour to the riverbed; so just, fluid is become washing away of bank slope and do not dash or alluvial, thereby reach the protection embankment; stablize toe; reduce the scour hole degree of depth; silt is faced and is made the beach; purposes such as river gesture are led in control.
Below with reference to accompanying drawing behind the literary composition the utility model content is described further.
Accompanying drawing is a perspective view of the present utility model.
As shown in the figure, four sides described in the utility model hexagon water-permeable frame by the six roots of sensation the isometric or six roots of sensation each other error in length be no more than ± 5% frame bar is interconnected to constitute, be positive triangular cone or nearly positive triangular cone, the length of side of frame bar and sectional dimension be according to coming husky condition of water and riverbed fringe conditions to determine, the connection of its joint can be adopted welding, colligation or form such as hinged.In the making, frame bar rod member can adopt making such as steel bar concrete prefabricated component, steel, and also the timber of available heavy burden, mao bamboon material etc. are made.Flood season is during shore protection, jettisonings in the entry organizing the framework of tying up bunchiness more, constitutes under water accumulation body to disperse current, dissipation water towards energy.In the practice of construction operation, efficient for guaranteeing to jettisoning, the number of every string frame is three to four, and for well, the bottom two or more rows of should jettisoninging forms stable frame group when jettisoninging, and reaches and piles high purpose with smooth-going layout shore protection.
Compared with prior art, the advantage that has of the utility model is:
1. adopt the steep bank of Triangular Taper Penetrating water-permeable frame protection river bank, obvious dispersing water flow, the punching of dissipation water are arranged The effect of energy, reduction water velocity, case history test effect show, under different water level combination, adopt This Triangular Taper Penetrating water-permeable frame can make Dou Kan limit flow velocity reduce by 30～70%;
2. utilize the Triangular Taper Penetrating water-permeable frame to construct protection works and need not down to bury the basis, easy construction can directly exist Carry out on the former landform elevation;
3. low, the good stability of four sides hexagon water-permeable frame center of gravity, adaptation deformation ability are strong, framework overturns in any case, its bottom lifting surface area all equates, and stress relative and other member effect of the same type and its bottom stress surface is also much smaller, is difficult for sinking on the silt bed surface;
4. the rod member of four sides hexagon water-permeable frame can be prefabricated with concrete, also available various steel, timber (heavy burden), mao bamboon material such as (heavy burdens), be convenient to batch production and produce in batches, and the constructed preventive works preventive works more constructed than traditional material of four sides hexagon water-permeable frame of utilizing above-mentioned material to make reduce investment outlay 30～70%.
