Description
Technical field
The utility model relates to a kind of protection submerged breakwater, is specifically a kind of ecological pipe bag submerged breakwater.
Background technology
Submerged breakwater is a kind of more conventional coast protection structure, and this structure end face is submerged under water when design high-water, when design lowest stage, can surface, and is generally enrockment submerged dyke or board plug type submerged breakwater.Traditional enrockment submerged dyke end face is positioned at the most concentrated region of Wave energy, and its institute's wave load that bears is larger, needs to adopt larger ground surface protection structure; In addition, enrockment submerged dyke is entity structure, under the impact of wave stream, easily empties phenomenon, makes submerged breakwater sinking or caves in and lose protective capacities; Qie China certain areas, geological conditions is poor, building stones comparatively lack and price higher, submerged breakwater is as adopted jackstone structure, construction costs is higher.If select board plug type submerged breakwater can effectively prevent from washing in a pan empty phenomenon, but plate need to be inserted to enough degree of depth, construction costs is higher.
Utility model content
The problem existing for prior art, the utility model proposes an a kind of ecological pipe bag submerged breakwater, by large-scale ecological pipe bag, is piled up and is formed, and has that sand control resistance wave is effective, cost is low and the simple feature of construction method.
The utility model solves the technical scheme of above technical problem: a kind of ecological pipe bag submerged breakwater is provided, and it is positioned at below the water surface, apart from bank certain distance, and parallel with water water front; Described submerged breakwater has double-layer structure, lower floor's submerged breakwater that it has is piled up and is formed by the ecological pipe bag of lower floor's waterproof sealing of the parallel filling sandy soil of two rows, and the ecological pipe bag of lower floor's waterproof sealing that length direction head and the tail are adjacent adopts the staggered connected mode of head and the tail to pile up, the upper strata submerged breakwater that described submerged breakwater has is piled up and is formed in the ecological pipe bag of upper strata waterproof sealing in the parallel ecological pipe bag of the lower floor's waterproof sealing centre position of described submerged breakwater two rows of lower floor by a ranking, and the gap between the ecological pipe bag of upper and lower two-layer waterproof sealing is filled with the described filling woven bag that is full of sandy soil; After the ecological geo-tube filling sandy soil of described upper and lower two-layer waterproof sealing, there is identical cross-sectional structure, described cross-sectional structure is that bottom is the class ellipse of straight line, it has the straight line that is positioned at the curve of top and is positioned at the described curve two-end-point of connection of below, and the cross section after the ecological pipe bag of upper and lower two-layer waterproof sealing of described submerged breakwater is piled up is " product " character form structure.
Submerged breakwater of the present utility model adopts the isosceles triangle mode of piling up to pile up, its structural base and bottom, riverbed contact area are large, wind and wave resistance Stability Analysis of Structures, because the cross section of its each pipe bag is class oval structure, when stormy waves impact tube bag, the energy of stormy waves can be effectively cushioned in the pipe bag outside of circular arc, greatly reduces the impact of stormy waves to riverbank bank protection and bank protection riverbed thereof; The pipe bag of submerged breakwater adopts staggered accumulation from beginning to end, can eliminate to greatest extent the capacity of anti-storm of submerged breakwater weak location, guarantees the effective stable protection effect of submerged breakwater.
The technical scheme that the utility model further limits is:
Aforesaid ecological pipe bag submerged breakwater, curve is parabolic curve, curve representation formula is: y=0.03x+0.005x
2; Bottom straight line after the ecological geo-tube filling sandy soil of the waterproof sealing of take and the intersection point of parabolic curve are initial point, as horizon, are abscissa x.Like this, by curve shape is set, when stormy waves impact tube bag, make to form aerated cavity between the ecological pipe of adjacent two waterproof sealings, thereby reach the longest maximum of aerated cavity, air entrainment is the most sufficient, makes the effect of the ecological pipe bag of water impact waterproof sealing weaken minimum; Can guarantee again not recall current under ecological pipe bag submerged breakwater, impact water flow stationary, played beyond thought technique effect simultaneously.
Aforesaid ecological pipe bag submerged breakwater, is provided with and inserts to water-bed guide pile in described ecology pipe bag both sides of piling up, and by rope, guide pile and ecological pipe bag is connected and fixed, and guarantees that ecological pipe bag can not occur to be significantly offset after filling soil.
Aforesaid ecological pipe bag submerged breakwater; described submerged breakwater and water depth are 100～200 meters, planting aquatic plants in this region, and the protection by submerged breakwater can form a metastable growing environment; the normal growth that is conducive to water plant, thus riverbank bank protection can more effectively be protected.
Aforesaid ecological pipe bag submerged breakwater, described ecological pipe bag is high-toughness polypropylene pipe bag.
An aforesaid ecological pipe bag submerged breakwater, described in to protect blanket be that high-toughness polypropylene spins geotextiles.
The beneficial effects of the utility model: ecological pipe bag of the present utility model adopts high-toughness polypropylene to have very high intensity and toughness, can resist the long-time repeated stock of current stormy waves, filling sandy soil piling up in ecology pipe bag, can form a high strength, high-quality, high density and the submerged breakwater that should not cave in, current and stormy waves are had to good resistivity, simultaneously because this product has acidproof, alkaline-resisting and corrosion resistant characteristic, can effectively protect for a long time the operating mode in cofferdam, this is not attacked by billow for protection water bank, the bottom between protection submerged breakwater and riverbank not shoal materials has important function, can maintain the stable ecological environment that riverbank water body plant is relative, reduce the impact of stormy waves on riverbank plants in water, stablize water-bed condition.
