Abstract
The utility model provides the groynes group under the condition of a kind of deep water low beach to protect beach structure, comprise the multiple groynes be arranged side by side along dykes and dams, bed protection structure has been constructed bottom groynes, described groynes is formed by the Non-submerged spur dikes section of offshore end and the submerged spur dike section of bank end far away, arranges ramp type linkage section between described Non-submerged spur dikes section and submerged spur dike section.The utility model is wider compared to the prior art scope of application, goes for the construction condition that outside levee toe, beach face change is complicated; Dam material consumption is few, and dam body structure is less, and construction costs is reasonable, is applicable to soft foundation condition.
Description
Technical field
The utility model relates to one and protects beach structure, particularly relates to a kind of groynes group be applicable under the condition of deep water shoal and protects beach structure.
Background technology
As a kind of engineering structures common in seashore tidal flats treatment, river training works and waterway regulation works, groynes has the effect of adjustment current, protection seashore, river bed contraction.According to the relation of crest elevation and water level, groynes can be divided into submerged spur dike and Non-submerged spur dikes.When crest elevation is lower than water level, there are more dam current in dam crest, groynes is called as submerged spur dike; Otherwise be called Non-submerged spur dikes.Usually adopt Non-submerged spur dikes pattern in seashore tidal flats treatment and river training works, in waterway regulation works, usually adopt submerged spur dike pattern.
Along with the development of China's seashore tidal flats treatment engineering and river training works in recent years, engineering construction condition is increasingly sophisticated.When present situation beach face is comparatively steep and river course major trough is close to dyke, protect beach before dike and adopt Non-submerged spur dikes structure simply, will there are the following problems: 1) levee body section is huge, in soft foundation situation, even if ramp type sloping breakwater is also difficult to the requirement meeting bearing capacity of foundation soil and monolithic stability.2) earth and stone material consumption is huge, and construction costs is high; If adopt submerged spur dike structure simply, then there is the problem that adjustment water flow effects is undesirable.
The problem obtaining desirable engineering effort is difficult to for solving increasingly sophisticated, the single groynes structural shape of construction condition, a kind of engineering effort that farthest can improve groynes structure of necessary searching, reduce banking material consumption, the rational groynes structural shape of construction costs.
Utility model content
Technical problem to be solved in the utility model is exactly for above shortcomings in prior art, there is provided the groynes structural shape that under the condition of a kind of deep water shoal, levee body section is little, banking material consumption is few, construction costs is low, engineering effort is good, for solving deficiency of the prior art.
For achieving the above object and other relevant objects, the utility model provides the groynes group under the condition of a kind of deep water low beach to protect beach structure, comprise the multiple groynes be arranged side by side along dykes and dams, bed protection structure has been constructed bottom groynes, described groynes is formed by the Non-submerged spur dikes section of offshore end and the submerged spur dike section of bank end far away, arranges ramp type linkage section between described Non-submerged spur dikes section and submerged spur dike section.
Further, the spacing between described multiple groynes is 3-5 times of single groynes length.
Further, groynes group comprises at least three groynes.
Further, the slope of described ramp type linkage section is than being 3-5.
Further, described ramp type linkage section is fan-shaped divergent shape.
By above technical scheme, the utility model has following technique effect compared to prior art:
(1) applied widely, go for the construction condition that outside levee toe, beach face change is complicated;
(2) dam material consumption is few, and dam body structure is less, is applicable to soft foundation condition;
(3) dam material consumption is few, and construction costs is reasonable.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this manual can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 3.Notice, structure, ratio, size etc. that this manual institute accompanying drawings illustrates, content all only in order to coordinate manual to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this manual as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
Consult shown in Fig. 1, the utility model provides the groynes group under the condition of a kind of deep water low beach to protect beach structure, comprises at least three groynes be arranged side by side along dykes and dams 5.Consult shown in Fig. 2 and Fig. 3, bed protection structure 4 has been constructed bottom groynes, each groynes is formed by the Non-submerged spur dikes section 1 of offshore end and the submerged spur dike section 3 of bank end far away, Non-submerged spur dikes section 1 and submerged spur dike section 3 all can adopt traditional dam material to construct, and arrange by offshore end to the fan-shaped divergent shape ramp type linkage section 2 of bank end far away between Non-submerged spur dikes section 1 and submerged spur dike section 3.
Wherein, Non-submerged spur dikes section 1 plays adjustment dike front outside flow-shape, stops beach face continuous erosion near levee toe, prevents channel thread from approaching the effect of levee toe, reach the function of protecting beach bank protection, its length is determined according to levee toe beach face regime width, is preferably 50-80m.
Submerged spur dike section 3 serves the effect stoping outside deep trouth beach face continuous erosion, steep bank unstability, reaches the object of deep trouth beach face outside stable levee toe, and its length, according to stable determination of outside deep trouth toe, is preferably 30-50m.
Ramp type linkage section 2 can adopt jackstone structure, and its length and slope are than according to the height of dam of Non-submerged spur dikes section 1 and dam body is stable determines, slope is than being preferably 3-5.
As further improvement of the utility model, the spacing between groynes is 3-5 times of single groynes length.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or changes.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that the utility model discloses, must be contained by claim of the present utility model.
