Description
Technical field
The invention belongs to rivers bank protection work technical field, particularly a kind of water-permeable frame that can collude certainly.
Background technology
After general Underwater Engineering (waterway regulation, dyke, bridge pier, port and pier etc.) is implemented; Flow dynamic changes greatly near the engineering works; Yi Yin along dike stream, Yue Diliu, stream, whirlpool etc. produces the local scour problem; Cause the local riverbed degradation of submerged structure serious, cause the abutment jackstone to cave in and fall generation landslide or collapse on the bank, jeopardize the safety and stablization of engineering structures; Also bring simultaneously the smooth implementation that engineering quantity strengthens, investment increases and incur loss through delay engineering, therefore need protect near the riverbed surface of the certain limit submerged structure.
Through for many years engineering practice and research, soft raft (adding concrete interlock block ballast or sand rib ballast) is proved to be one of more excellent river bottom protection structure of effect, has been widely used in domestic and international water conservancy, the marine traffic engineering.It is firm relatively that its main advantage is to arrange the body self structure, can adapt to the beach face river-bed deformation of certain amplitude, less to local current change, do not influence flood passage, shipping etc.
In soft raft utilization reality for many years, also exist following several problem and perplexing water conservancy marine traffic engineering circle:
(1) under the effect of local current, row know from experience occur washing away of degree varies collapse, arrange tear, arranging is exposed to outer even the phenomenon such as unsettled of arranging, and needs certain regular maintenance work of later stage;
(2) especially at the edge of soft raft or the gradient is bigger, landform changes violent slightly place, ballast can break away from soft raft because of the variation unstability of terrain slope, cause soft raft to be raised or tear because of losing ballast protection quilt, and safeguard function partly reduces or loses;
(3) to arrange construction requirement higher for soft raft, needs certain professional equipment, and have also that the subaqueous construction location is difficult, the rafting ERROR CONTROL is difficult, seam and irregular section linking, last person's upset, arrange problems affect soft raft river bottom protection effects such as body contraction, late detection difficulty;
(4) when the gradient under water is big, be not suitable for the soft raft river bottom protection.
For many years; Domestic and international many engineering units have carried out certain exploration and research with regard to how to optimize and promote soft raft river bottom protection effect always; But all be difficult to fundamentally overcome an above-mentioned difficult problem basically, visible this problem has become one of decision hydraulic engineering key of success problem.
Cause the key problem of soft raft destructible to be to arrange the poor effect that body self is subdued flow energy, can not on row's body, utilize natural silt to increase ballast (short silt poor effect), and under instability condition, not possess interlock and link effect.
In the reality of middle and lower reach of Yangtze River bank protection work, improved soft raft technology has appearred, and as shown in Figure 1, it mainly is dangerous section dangerous section and the common just triangular centrum water-permeable frame of row's body edge increase that is prone to destruction at row's body.Major defect through the common just triangular centrum water-permeable frame of engineering practice proof is:
On the one hand, because the weight of single just triangular centrum water-permeable frame is less, when the approach velocity of current increased, the active force that current align triangular centrum water-permeable frame also increased, and caused just triangular centrum water-permeable frame slip, the unstability of rolling easily; On the other hand; Because the resistance effect of just triangular centrum water-permeable frame group; Water flow structure and vortex system of forming around it can make the buffer zone edge occur darker jet-bedding everywhere, and when jet-bedding reaches certain slope, thereby frame body can tumble and loses the beach face ballast in the jet-bedding and guard effect.
Although the mode that adopts the series connection crowd to throw with regard to the relatively poor problem of linking property of water-permeable frame body in the current engineering construction is improved more; But also cause its attaching property variation to river-bed deformation; Cost increases; The requirement of tackling construction technology mutually also uprises, and yet is difficult to the situation of avoiding ballast unstability and row's body to destroy simultaneously.
