Description

River course truss-like draws anchor means for preventing driftage
Technical field
This utility model relates to the river course means for preventing driftage of a kind of hydraulic engineering, especially relates to the purlin, river course that a kind of hydraulic engineering is passed the flood period Posture draws anchor means for preventing driftage.
Background technology
In water conservancy flood retarding project process of construction, owing to river course is dammed, diversion tunnel started water, when only diversion tunnel crosses water, Owing to the cross-section of river is less, it is difficult to by upstream floating thing, shrub and haystack and building waste in groups, thereby result in diversion tunnel Blocking, lifting river water level, have a strong impact on barrage building and pass the flood period safety.Therefore, the mode that drift-net pocket is blocked in general employing intercepts Floating thing.Flood retarding project construction period river course needs to meet the basic functions such as draining dado unobstructed, anti-flood requirement, and means for preventing driftage is usual Fairly simple, following several structural shapes: (1) blocks drift-net;(2) anti-floating cylinder;(3) drift row is blocked.
When water conservancy flood retarding project is built, general drift measure of blocking is that drift-net is blocked in erection, traditional block drift-net and to select in two sides, river course The anchor point taken, blocks drift-net mesh diameter less and obvious by windage, blocks drift-net main rope easy to wear, the floating thing of interception The most disposable, block drift-net and be not suitable with the factors such as river course that riverbed changes greatly.Therefore, comprehensive shadow need to be considered when drift-net is blocked in selection The factor of sound.
In water conservancy flood retarding project, being arranged on of anti-floating cylinder external is used more, mainly relies on the floating drum of different-diameter to float on not With on the water surface of the degree of depth, make full use of the angle of flow direction and floating drum and meet and lead drift effect, owing to floating drum floats on water surface difficulty With fixing, joint easy jam floating thing between floating drum, model need to be set up and calculate and can implement, when selecting anti-floating cylinder difficulty big, Cost is high, is not suitable for extensively applying.
When water conservancy flood retarding project is built, drift row is also blocked in the general drift measure of blocking used, and traditional blocks drift row mainly in river course Built-in concrete foundation, supporting structure, transition buoyancy tank etc. form, need to consider engineering site orographic condition, geological condition, The hydrologic regime in river, engineering place, floating thing number, maximum floating thing etc., determined the supporting blocking drift row by force analysis Version.Therefore, blocking drift row's complex structural designs, construction cost is higher, needs to the greatest extent may be used on the premise of meeting engineering function Simple supporting structure form can be used to reduce construction costs.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, it is provided that a kind of river course truss-like draws anchor means for preventing driftage, full Foot is passed the flood period and is blocked the function of drift (floating log, shrub, in groups haystack, building waste etc.) simultaneously, and river training water quality improves water conservancy diversion Hole conveyance capacity, prevents diversion tunnel from blocking, and effectively reduces flood control water level, have easy construction, environmental protection, widely applicable, block drift Effective, the feature of safety economy.
