Abstract
The utility model relates to a hydraulic engineering technical field, concretely relates to cut short silt dyke of tide. Setting up geotechnological non -woven fabrics layer on the mud flat, setting up the flat bottom protection of throwing layer on the geotechnological non -woven fabrics layer, flatly set up left dam body and right dam body on throwing the bottom protection layer, it has core mud to fill between left dam body and the right dam body, and left dam body and right dam body fill by the braided bag of the different external diameters of a plurality of layers of outsourcing nonwovens geotechnique cloth and form, left side dam body and right dam body are formed with the dam facing of locating basic dam crest portion by trapezoidal ji ba, and the dam facing of left dam body forms the step for its basic dam adduction, and the dam facing of right dam body is unanimous rather than jiba's side. The structural strength of this dyke is high, satisfies the high strength requirement of rough swell tidal zone, the main part is stable, the soft basic condition of adaptation silt.
Description
Technical field
This utility model relates to hydraulic engineering technical field, is specifically related to a kind of tide that cuts and promotees silt dike.
Background technology
China's rivers are numerous, founding of New is over more than 50 year, especially through the practice of more than 20 years large and medium water power station engineering, water conservancy diversion dams and the design of coffering and construction level improve rapidly, as Ge Zhou Ba, the Changjiang river, damming the Yangtze River of Three Gorges Projects the most all indicate that China dams on great rivers and builds cofferdam technology and ranked among the international rank of advanced units.But the dam project that mountain area rivers are mainly implemented by above-mentioned engineering, they have individual feature, basis is rock, belong to hard basis, although damming, Longkou flow velocity is bigger, but substrate scour depth will not be aggravated, construction section keeps certain, use the vertical stifled method effect of branched dike in an opposite direction notable, and it is the most few to the successful experience of Plain Soft Soil river cut-off, such as Yangtze River Delta silt area, particularly Hangzhou Wan tidal bore zone, basis is the soft base of silt being easily washed, need plus because of urban development and hydraulic engineering construction, cofferdam construction is implemented in Tidal flat lower ground district, straight stifled method is the most inapplicable.
Concrete, after Longkou is formed, near dike Longkou, there is a deeper scour hole in an opposite direction, preferred plan is that in using, block up method in cofferdam.Interior cofferdam is divided into three limits totally three back levee line, left side dike length is generally 120～150m, opposite, dike Longkou dike line length is generally 200～250m in an opposite direction, right side dike length is generally 120～150m, the characteristic easily formed inside dike in an opposite direction according to trend ditch, is set to the side dike line by tidewater frontal impact Longkou, interior cofferdam, also referred to as blocks up and cut Chao Di, the side dike line being formed trend ditch by tidewater backflow is referred to as cutting tide rush silt dike, and opposite, dike Longkou dike line is referred to as general section dike in an opposite direction.And the tide that cuts for being applied at present on the soft base of the silt of tidal bore zone promotees silt dike, structure exists service life and intensity defect.Therefore, the dykes and dams on a kind of soft base of silt being applicable to tidal bore zone are needed badly to meet the requirement of real work.
Summary of the invention
The purpose of this utility model is the problem in order to solve current above-mentioned existence, it is provided that a kind of tide that cuts promotees silt dike.
In order to reach foregoing invention purpose, this utility model by the following technical solutions:
A kind of tide that cuts promotees silt dike, beach arranges geotechnique's nonwoven layer, in geotechnique's nonwoven layer, bedding course layer is set, left dam body and right dam body are set on bedding course layer, it is filled with core mud between left dam body and right dam body, forms if left dam body and right dam body are filled by the woven bag of the various outer diameter of dried layer outsourcing non-woven geotextile；Left dam body and right dam body are by trapezoidal Ji Ba and the dam facing composition being located at base dam crest portion, and the dam facing of left dam body forms step relative to receiving in its base dam, and the dam facing of right dam body is consistent with the side of its Ji Ba.
As preferably, it is provided with a cubic metre of earth back-up coat outside left dam body, bottom earthwork back-up coat, is provided with casing.
As preferably, the outer slope of the Ji Ba of left dam body is 1:3, and the inner side gradient is 1:0.77；The outer slope of the dam facing of left dam body is 1:1.5.
As preferably, the Ji Ba of right dam body and the outer slope of dam facing are 1:1.5；The inner side gradient of Ji Ba is 1:1.5.
As preferably, described bedding course layer be thickness be the river bottom protection stone of 2-3m.
As preferably, described geotechnique's nonwoven layer uses steel nail to fix.
As preferably, the lateral surface of right dam body is provided with ripple glaze, and described ripple glaze matches with its layer structure.
As preferably, less than bottom left dam body bottom right dam body.
This utility model compared with prior art, provides the benefit that: structural strength is high, meets the high intensity requirement of tidal bore zone；Soil stability, adapts to silt soft base condition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 geotechnique's nonwoven layer, 2 bedding course layers, 3 left dam bodys, 4 right dam bodys, 5 core mud, 6 Ji Ba, 7 dam facings, 8 steps, 9 cubic metres of earth of back-up coats, 10 casings, 11 ripple glazes.
