Abstract
It the utility model is related to a kind of guarantor's beach dykes and dams top filtration, including waterproof levee body (4), the top of the waterproof levee body sets hybrid filtering layer, the hybrid filtering layer is mainly spaced apart and formed by gravel (1), bagged sand (2) and very fine sand (3), the gravel is located proximate to guarantor beach dam slope face, the very fine sand is distributed in the middle part of levee crown, and the bagged sand is distributed between gravel and very fine sand.The waterproof levee body is preferably formed by fissure of displacement laying above and below several layers of mud filling tube bag.The concentration of hydraulic mixture of filling is 20% -45% in the mud filling tube bag.The utility model structure durable, securely, both can guarantee that the basic function on beach dam, and and can realizes that water body exchanges by material rational gradation composition in mixing drainage layer, takes into account the function of draining and filtering, while substantially reduce the cost of dam body.
Description
Technical field
Bao Tan dams are the utility model is related to, especially, is related to a kind of guarantor's beach dykes and dams top filtration, belongs to guarantor's beach engineering and apply
Work technical field.
Background technology
In hydraulic engineering, conventional Bao Tan dams much use water penetration rock weir, can choose a part of current from riverbank,
Start to control and lead flow action, another part current flow to dam field through rock weir, slow down flow velocity, make sedimentation, reach unhurried current and fall
Silt effect.But because jackstone unit price is higher, make the overall cost of permeable dike also very high.If using impermeable dam, can reduce
The cost of dam body, but impermeable dam can raise water level in embankment, and seepage failure can be caused to embankment inner side by enclosing the too high result of water,
Exchanged simultaneously because enclosing Nei Shui with lacking flowing outside dam, promote nutrient concentrations increase in water, algae excessive propagation, make to enclose interior water
Matter is by a certain degree of pollution.
Beach engineering is protected for part, half permeable Bao Tan dams have no effect on it and protect beach effect, in order to avoid because of waterproof section
Excessive height, it is too high to cause to enclose water, to causing seepage failure on the inside of embankment, if below levee crown, more than waterproof levee body
Region use hybrid filtering Rotating fields, then can solve the problems, such as that prior art is present.
Utility model content
Technical problem to be solved in the utility model is that providing one kind protects beach dykes and dams top filtration, and use is waterproof
Levee body is combined with mixing drainage layer, can be ensured the antiseepage safety of a line embankment and can be realized that water body exchanges.
In order to solve the above problems, the technical solution adopted in the utility model is as follows：
One kind protects beach dykes and dams top filtration, including waterproof levee body, and the top of the waterproof levee body, which is set, to be mixed
Filtering layer, the hybrid filtering layer is mainly spaced apart by gravel, bagged sand and very fine sand to be formed, and the gravel is located proximate to protect
Beach dam slope face, the very fine sand are distributed in the middle part of levee crown, and the bagged sand is distributed between gravel and very fine sand.
Preferably, the waterproof levee body is formed by fissure of displacement laying above and below several layers of mud filling tube bag.
Preferably, the concentration of hydraulic mixture of filling is 20% -45% in the mud filling tube bag.
In order that hybrid filtering layer has a bigger discharge capacity, the hybrid filtering layer cobble-stone, bagged sand, fine sand
Volume ratio is 5:4:1, hybrid filtering layer infiltration coefficient is 4.9 × 10-1cm/s.
Principle of the present utility model is the structure being combined using waterproof levee body with hybrid filtering layer, hybrid filtering layer
Function one be that can enclose interior water level with draining and be down to waterproof levee body elevation, ensure a line embankment behind the unrestrained top of typhoon climax levee body
Antiseepage safety；Discharged second, can usually supplement clean sea water at the incoming tide, during ebb tide, be advantageous to improvement and enclose interior water quality.It is mixed to reach
The difference for closing filter layer changes water demand, and it is wide that gravel, bagged sand, the distribution in the respective region of very fine sand can be adjusted according to engineering demand
Degree.
To sum up, compared with prior art, the beneficial effects of the utility model are：
The utility model structure durable, securely, the basic function on beach dam was both can guarantee that, and can is by mixing drainage layer
Interior material rational gradation composition realizes that water body exchanges, and takes into account the function of draining and filtering, while substantially reduces the cost of dam body.
Brief description of the drawings
Fig. 1 is the structural representation of the preferred embodiment of the utility model one.
In figure：1st, gravel；2nd, bagged sand；3rd, very fine sand；4th, waterproof levee body.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.Said according to following
Bright, the purpose of this utility model, technical scheme and advantage will be apparent from.It should be noted that described embodiment is this
The preferred embodiment of utility model, rather than whole embodiments.
With reference to shown in Fig. 1, one kind protects beach dykes and dams top filtration, including waterproof levee body 4, the waterproof levee body it is upper
Side sets hybrid filtering layer, and the hybrid filtering layer is mainly spaced apart and formed by gravel 1, bagged sand 2 and very fine sand 3, described
Gravel is located proximate to protect beach dam slope face, and the very fine sand is distributed in the middle part of levee crown, the bagged sand be distributed in gravel with it is superfine
Between sand.The waterproof levee body infiltration coefficient is smaller, is preferably formed by fissure of displacement laying above and below several layers of mud filling tube bag.It is described to fill mud
The concentration of hydraulic mixture of filling is 20% -45% in pipe bag.Preferably, the hybrid filtering layer cobble-stone, bagged sand, fine sand
Volume ratio is 5:4:When 1, by with bigger discharge capacity, hybrid filtering layer infiltration coefficient is about 4.9 × 10-1cm/s,
In the case that material is highly consistent in hybrid filtering layer, its width ratio is 5:4:1.
Principle of the present utility model is the structure being combined using waterproof levee body with hybrid filtering layer, hybrid filtering layer
Function one be that can enclose interior water level with draining and be down to waterproof levee body elevation, ensure a line embankment behind the unrestrained top of typhoon climax levee body
Antiseepage safety；Discharged second, can usually supplement clean sea water at the incoming tide, during ebb tide, be advantageous to improvement and enclose interior water quality.It is mixed to reach
The difference for closing filter layer changes water demand, and it is wide that gravel, bagged sand, the distribution in the respective region of very fine sand can be adjusted according to engineering demand
Degree.
It is described above, only it is the description explanation of the utility model preferred embodiment, not to scope of protection of the utility model
Restriction, it is clear that any those skilled in the art are based on above-described embodiment, can readily occur in replacement or change to obtain
Other embodiment, these all should cover within the scope of protection of the utility model.
