Description
Technical field
The present invention relates to dykes and dams protection technology fields, in particular to a kind of antiseepage dykes and dams.
Background technique
Currently, in the process of processing, mostly using concrete cut, high-pressure rotary jet grouting pile etc. anti-to Dam Foundation with Serious Leakage
Infiltration mode is reinforced, and concrete is injected into the dam foundation by this mode, in the construction process, inevitably generates shadow to underground water
It rings, and cost is higher, while Anti-seeping technology, the combination of two kinds of materials is carried out to dam body and the dam foundation according to different materials
Place, which inevitably generates, to be washed away, and the safety of impervious body and dam body is jeopardized.
Summary of the invention
At least one in order to solve the above-mentioned technical problem, the purpose of the present invention is to provide a kind of antiseepage dykes and dams.
To achieve the goals above, technical solution of the present invention provides a kind of antiseepage dykes and dams, comprising: dykes and dams, including dam
Body and the dam foundation being connected with the bottom of the dam body；Leakage preventing structure, covers at least partly side wall surface of the dam body, and to downward
The bottom of the dam foundation is extended to, and the leakage preventing structure is an integral structure.
The antiseepage dykes and dams that technical solution of the present invention provides, comprising: dykes and dams and leakage preventing structure.Dykes and dams include dam body and and dam
The connected dam foundation in the bottom of body, leakage preventing structure has antiseepage effect, by at least partly side that leakage preventing structure is covered on to dam body
On wall surface, and the bottom of the dam foundation is extended downward into, dam body and the dam foundation is made to be provided with antiseepage function, improves the anti-of the dam foundation and dam body
Permeability, it is therefore prevented that the dam foundation and dam body influence its safety because of water saturates, and since leakage preventing structure is an integral structure, one
Formula structure can effectively avoid in the prior art due to the dam foundation and dam body seepage structure are using different materials caused by contact scour
Problem, so that the safety of antiseepage dykes and dams is effectively increased, simultaneously as antiseepage dam configuration provided by the present application is more simple
It is single, convenient for construction, to effectively reduce the construction cost of scheme.
In addition, the antiseepage dykes and dams in above-mentioned technical proposal provided by the invention can also have following additional technical feature:
In the above-mentioned technical solutions, recess forms shuting downwards for the dam foundation part, and the leakage preventing structure includes covering
The impervious barrier of at least partly side wall surface of the dam body and the barrier matrix being filled in the shuting.
Leakage preventing structure includes impervious barrier and barrier matrix, and recess is formed with shuting downwards for dam foundation part, by by antiseepage
Matrix is filled in shuting, so that shuting be made to be provided with antiseepage function, effective wall surface water is permeated to the dam foundation, is passed through
Impervious barrier is covered in at least partly side wall surface of dam body, so that dam body be made to be provided with antiseepage function, effectively prevent water to
Dam body is permeated, and improves the safety of antiseepage dykes and dams entirety.
It is worth noting that the longitudinal section of shuting is trapezoidal, range of the trapezoidal base width in 800mm~1200mm
Interior, the side slope ratio of two bevel edges is 1:1.

At the connecting portion of body, lean with the leakage preventing structure, the position for fixed shown leakage preventing structure.
Antiseepage dykes and dams further include buttress, by the way that buttress is arranged at the connecting portion of impervious barrier and barrier matrix, and with
Leakage preventing structure leans, and buttress plays the role of fixed leakage preventing structure, effectively prevent leakage preventing structure by water punching across or break up and
Dam body and the dam foundation is set to lose antiseepage function.
In the above-mentioned technical solutions, the buttress is concrete buttress；And/or the longitudinal section of the buttress is in rectangle.
Buttress is concrete buttress, and concrete buttress intensity is higher, improves the intensity of buttress, to make buttress to antiseepage
The fixation of structure is stronger, while keeping the structure of antiseepage dykes and dams more stable.
The longitudinal section of buttress is in rectangle, and rectangular configuration is more smooth, and rectangular configuration shape is more regular, convenient for being constructed into
Type helps to improve the stability to leakage preventing structure fixed function, and helps to improve the aesthetics of antiseepage dykes and dams.
It is worth noting that the width of buttress is in the range of 400mm~600mm, highly in the model of 480mm~720mm
In enclosing, and the strength grade of buttress is C20.
In the above-mentioned technical solutions, the leakage preventing structure is caly structure.
Leakage preventing structure is caly structure, and leakage preventing structure compactness made of caly structure is larger, and water is not easy to be impregnated with, effectively
The barrier properties of antiseepage bottom plate are improved, and caly structure construction cost is lower, is convenient for construction molding.
In the above-mentioned technical solutions, the antiseepage dykes and dams further include: protective layer is laid on the caly structure and is covered on institute
It states on the part in the side wall surface of dam body.
Antiseepage dykes and dams further include protective layer, and protective layer is laid on the part that caly structure is covered in the side wall surface of dam body
On, play the role of protecting caly structure, caly structure is prevented to be covered on the part in the side wall surface of dam body by broken off by water flush or punching
Collapse, the antiseepage of antiseepage dykes and dams is acted on to further improve caly structure.
In the above-mentioned technical solutions, the protective layer includes the side wall for being laid on the caly structure and being covered on the dam body
Sand stone layer on part on face and the concrete layer being cast in the sand stone layer.
Protective layer includes sand stone layer and concrete layer, by the way that sand stone layer is laid on the side wall that caly structure is covered on dam body
On part on face, caly structure is reinforced, and concrete layer is cast in sand stone layer, plays the work of fixed sand stone layer
With, while reinforce caly structure further, effectively increase the compression strength of caly structure.
It is worth noting that the thickness of sand stone layer is in the range of 80mm~120mm, and the strength grade of sand stone layer is
C15, the thickness of concrete layer is in the range of 80mm~120mm, and the strength grade of concrete layer is C15.
