Abstract
The invention discloses an ecological backwater type beach protection structure. The ecological backwater type beach protection structure is a precast concrete block pressure carrier. The precast concrete block pressure carrier is provided with a bottom plate. The center of the upper surface of the bottom plate is provided with an arch structure in the length direction. The length of the arch structure is equal to the width of the bottom plate. Compared with a traditional pressure carrier, the ecological backwater type beach protection structure can effectively increase the roughness of the bed for facilitating silt sediment when the water surges to the beach during flooding for further improving beach protection effects; in addition, the precast concrete block pressure carrier is hollow for slowing down the flow resistance as well as enabling the water to flow through for further enriching the change of the flow field around the beach, and the hollow precast concrete block structure also provides activity space for aquatic animals to improve the ecological environment around the beach to some extent.
Description
Technical field
The present invention relates to one and protect beach structure, be specifically related to a kind of ecology type of choking water and protect beach structure.
Background technology
Along with the expansion that deepens continuously of China's waterway regulation works, the type of regulating structure gets more and more, and wherein protecting beach building has become a kind of important waterway regulation pattern.Existing beach structure of protecting is roughly divided into three classes at present: block protects beach, dam body protects beach, soft raft protects beach in loose throwing.Loose block of throwing protects beach and mainly refers to jackstone and protect beach, namely on beach face, the block stone of loose throwing about 50 ~ 80cm carries out protecting beach, it be mainly used in the depth of water less (being generally less than 3m), flow velocity little (being generally less than 1.5m/s), river-bed deformation comparatively slowly, the good section of geological conditions, as pebble beach or sandy gravel beach, hydraulic department has application more.Dam body protects beach and mainly refers to reach the effect of protecting beach by construction dam body or dam body group, and dam body form has groynes, longitudinal dike, closure dam, ground sills etc.To be called from the soft raft of erosion damage for shore protection and protection beach, continent and to protect beach soft raft, protect beach soft raft and be in fluctuation of water table area, flood flood period under water, by current scour, dry season surfaces, and is exposed to the sun and rain.The nineties, protected beach soft raft and started to be applied in waterway regulation works last century, was a kind of comparatively novel waterway regulation fabric structure pattern.Its main building thing is tying ballast soft raft, and the ballast carrier of the row's pad be made up of geotextiles and the upper tying some of row's pad forms.Soft raft is laid on the beach body that need protect, the husky body below isostere is played a protective role, and makes it from erosion damage.Protect this structure of beach soft raft and be mainly applicable to the favourable section of river potential condition, already present comparatively tall and big complete beach, continent is guarded, transforms to unfavorable direction to prevent Channel Condition.Relative to traditional all kinds of dam bodys, protect beach building and do not change current and rule of sediment movement, small investment, construction easily, and often produces the effect of getting twice the result with half the effort.But from the waterway regulation works implemented at present, adopted protect beach soft raft impaired or destroy phenomenon comparatively serious, directly affect waterway regulation effect, in addition after existing shoal protection works is implemented, substantially there will not be the phenomenon that silt falls to becoming silted up, and edge, Project Areas and there will be washing away to a certain degree with exterior domain, be also disadvantageous to the stable of building.Its main cause is: although the beach isostere of protecting of the above beach face of low water level is flexible structure comparatively speaking, and isostere destroys the bed ripples rolling shape of original natural bed surface after laying, ballast carrier surfacing, and corner angle are clearly demarcated, and head erosion damage is serious.Therefore a kind of new in the urgent need to developing, can available protecting beach body, be also conducive to silt and fall to becoming silted up.
Summary of the invention
The present invention provides a kind of ecology type of choking water to protect beach structure for solving in known technology the technical problem that exists; this structure is applicable to beach body protection, and beach body can be protected from erosion damage, is conducive to again silt and falls to becoming silted up; mould beach volume morphing better, can also improve the ecological environment to a certain extent.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is: a kind of ecology type of choking water protects beach structure, this protects beach structure is Prefabricated Concrete block ballast carrier, described Prefabricated Concrete block ballast carrier is provided with base platform, the upper surface of described base platform is provided with domes along its length between two parties, and the length of described domes is equal with the width of described base platform.
The semicircular ring of the facade of described domes to be internal diameters be 40cm.
The thickness of described domes is 10cm.
The length of described base platform is 80cm, and width is 40cm, is highly 10cm.
Advantage of the present invention and good effect are:
One) surface layer of ballast carrier is designed to wavy pattern, compared with traditional ballast carrier, effectively can increase the roughness of bed surface, on middle flood period current behind beach, is conducive to silt and falls to becoming silted up, protect beach effect and strengthen; Two) Prefabricated Concrete block ballast carrier adopts hollow-core construction, not only can overcurrent but also can slow down resistance to water-flow, enriches the flow field change around the body of beach; Three) adopt engraved structure, for aquatic animals and plants provides activity space, thus improve the ecological environment around the body of beach to a certain extent.

Fig. 3 is the lateral view of Fig. 1.
Detailed description of the invention
In order to summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 3, a kind of ecology type of choking water protects beach structure, this protects beach structure is Prefabricated Concrete block ballast carrier, described Prefabricated Concrete block ballast carrier is provided with base platform 1, the upper surface of described base platform 1 is provided with domes 2 along its length between two parties, and the length of described domes 2 is equal with the width of described base platform 1.
In the present embodiment, the semicircular ring of the facade of described domes to be internal diameters be 40cm.The thickness of described domes is 10cm.The length of described base platform is 80cm, and width is 40cm, is highly 10cm.The plane configuration of above-mentioned Prefabricated Concrete block is rectangle, and plane meter modest ability × wide is 80cm × 40cm, and facade shape is bed ripples shape, and maximum height is 40cm.
Although be described the preferred embodiments of the present invention by reference to the accompanying drawings above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, can also make a lot of pattern, these all belong within protection scope of the present invention.
