Description
Technical field
The utility model relates to a kind of leakage preventing structure, in particular for the seepage control of dam structure on the Hydraulic and Hydro-Power Engineering.
Background technology
At present, extensively adopt local material dam patterns such as clay homogeneous dam, calculous soil core-wall (sloping core) loose rock dam, Concrete Face Rockfill Dam, pitch core-wall (sloping core) loose rock dam on the Hydraulic and Hydro-Power Engineering, corresponding dam body seepage material generally adopts calculous soil material, concrete slab, bituminous concrete, geomembrane, geotechnological plant etc.Geosynthetics generally is used for the temporary works antiseepage.When adopting high calculous soil core-wall (sloping core) dam, its impervious material consumption is big, haul distance is far away, its quality does not often satisfy the requirement of building a dam, blending technology is not only complicated, also need the place of certain area, in addition to time of antiseepage earth material exploration, experimental study also for a long time, content is a lot, delayed the hydroelectric development process to a certain extent; Adopt when building a dam on the local material basement rock, often preferentially select Concrete Face Rockfill Dam, concrete slab is used for the antiseepage of whole dam body as face slab for water retaining, but build highly above behind the 200m, because the deflection of enrockment is big under water pressure and self-gravity action, all side seam sealings and panel crack often become the maximum hidden danger of design, operation, the crack of causing for the distortion sedimentation that reduces the dam body enrockment etc. is to the influence of dam body operation, the concrete panel must the dam body enrockment fill and natural subsidence could construct after a period of time, thereby prolonged the cycle of building the dam.The impervious material of building high loose rock dam selection on the deep covering layer is limited, the stress of impervious wall can't accurately calculate with existing theory, to the material requirements height, influenced by the construction speed arrangement, the employing of impervious wall and core-wall joint design pattern also is the new problem that needs research.Can satisfy and build a dam and force request, utilize the design theory of Concrete Face Rockfill Dam, avoid the shortcoming of Concrete Face Rockfill Dam, seeking new antiseepage pattern and material is the ideal that each hydroelectric project teacher dreams of.
The utility model content
Technical problem to be solved in the utility model provides a kind of to the strong seepage control of dam structure that also can satisfy whole barrier performance of dam body stress deformation compliance.
The technical scheme that its technical problem that solves the utility model adopts is: this seepage control of dam structure comprises the dam body that is provided with dam foundation impervious wall, the antiseepage coping is provided with reinforced concrete foundation, be provided with the metal impervious barrier of integral solder structure at the bottom of extending to the dam from the top of dam body, the bottom of metal impervious barrier is inserted into and forms the antiseepage syndeton in the reinforced concrete foundation.The metal impervious barrier adopts the good metal sheet integral solder of ductility to form, and compensates with the distortion to dam body, strengthens the compliance of its metal impervious barrier to dam deformation, thereby improves its whole barrier properties and durability.
As to further improvement in the technical proposal, the metal impervious barrier comprises straight plate and corrugated sheet, and straight plate and corrugated sheet space also are welded as a whole, and make full use of the distortion that the bigger ductility of corrugated sheet adapts to and compensate dam body.
The metal sheet of making the metal impervious barrier is copper coin or corrosion resistant plate.
The beneficial effects of the utility model are: because the metal impervious barrier that has adopted the good metal sheet integral solder of ductility to make can reliably be connected with peripheral leakage preventing structure preferably, make its all side seam sealing convenient and reliable.Metal sheet is copper coin and corrosion resistant plate has good endurance, advantages such as ductility is good, corrosion resistance is strong, welding procedure maturation especially, in traditional leakage preventing structure, copper sheet or other rigidity thin plates are only selected for use as the structural joint sealing for a long time, the metal impervious barrier that the utility model adopts the metal sheet integral solder to make, avoid the formation of structural joint, reduced the link of antiseepage.With metal sheet especially subwave card dam deformation is compensated, also can effectively avoid metal impervious barrier tension to form the crack, it is strong that the metal impervious barrier adapts to the dam deformation ability, can satisfy on the basement rock and the requirement of building high dam on the covering layer, can effectively save construction investment.To building high loose rock dam on the covering layer; concrete cut can be placed on outside the dam body; simple in structure; structure stress is clear and definite, and grouting construction time assurance degree height also can reduce calculous soil material consumption under the wall; can reduce cultivated land occupancy, reduce immigrant's resettlement and reduce vegetation deterioration; save the dam body heap amount of building, thereby save construction investment, help the protection of environment.The utility model construction restraining factors in the process of implementing are few, can reduce the time and the expense of stock ground exploration, material laboratory test and field compaction test, save design is taken greatly, the technical barrier of building high loose rock dam on the deep covering layer that present this area is generally run into is readily solved, the comprehensive technology economic indicator is good, is suitable for using in rock and core wall rockfill dam engineering.
