Description
Technical field
The utility model belongs to Hydraulic and Hydro-Power Engineering technical field, relates to a kind of high rock, particularly relates to a kind of high rock multistage panel construction.
Background technology
In Hydraulic and Hydro-Power Engineering, because irrigation draught or generating etc. need, the formation reservoir of conventionally will building a dam.Dam mainly contains the type such as concrete dam and loose rock dam, and in loose rock dam, conventional dam type has core wall rockfill dam and reinforced concrete face rockfill dam.Along with dam construction technique fast development, 300m level Clay Core Wall Rockfill Dam, the arched concrete dam of 300m level, 300m level concrete gravity dam, 200m level rock are developed at present.
For further developing the western abundant hydraulic power potentials of China, west area has the superelevation dam of a collection of 300m level yet to be built, the phenomenon of the features as poor geologic conditions such as west area ubiquity relief joint growth, exist traffic very inconvenient simultaneously, the material such as cement and steel haul distance is far away, and therefore loose rock dam have advantages of strong adaptability and reduced investment.In addition, west area quality of earth material is bad, and earth material source is less, if select Clay Core Wall Rockfill Dam, exploits earth material and need take a large amount of soils, increases immigrant, and has greater environmental impacts, and therefore, rock more can adapt to west area compared with core wall rockfill dam.But, arrange and build the high rock of 300m level because dam body thrust enlarges markedly, can produce larger horizontal movement, thereby affect the safety of face joint water stop system.
For the horizontal movement that reduces to cause because of hydraulic thrust, application number is that 201120470153.4 Chinese utility model patent discloses a kind of rock compound with gravity dam, it is the upstream concreting gravity dam in rock bottom, on the basis of gravity dam, build rock, gravity dam is relatively not produce the rigid body of horizontal movement.Although adopt this technical scheme to can be controlled in 250mm in the horizontal movement of Water Pressure lower panel loose rock dam, can meet the joint seal requirement of current rock, there is the distortion that adjustable weight Ba Qu Yu Zhu rockfill area is set in the dry lean concrete district of low elastic modulus, make dam structure stable.But in actual application, the distortion of panel rear stockpile easily causes that panel comes to nothing, and destruction even fractures.
Utility model content
In order to address the above problem, the utility model provides a kind of high rock multistage panel construction, fractures and comes to nothing problem to solve concrete slab.
The utility model is achieved by following technical solution.
A kind of high rock multistage panel construction, mainly formed by concrete slab and base concrete, be equipped with the Transition Materials of 1～3m thickness in base concrete and rockfill connecting part, between Transition Materials and concrete slab, be provided with padding layer, described base concrete is 2～5 layers, by this base concrete, the concrete slab of high rock is divided into multistage, and every section is highly less than 200m.
Described base concrete comprises base foundation concrete and multistage middle part base concrete.
Described concrete slab comprises I phase base concrete panel, II phase concrete slab and III phase concrete slab.
Described middle part base concrete is connected with Multi-section concrete panel by longitudinal vertical lap seam respectively.
Between described every section concrete panel, be connected by constuction joint.
The beneficial effects of the utility model are:
Compared with prior art, rock panel construction described in the utility model is by utilizing 2～5 layers of base concrete that the panel of superelevation rock is carried out to segmentation, every section high is controlled in 200m, every section of panel top 5～10m scope panel is constructed before its whole panel construction end or retaining, and total height of dam is controlled in 350m.Like this can be by the section construction of multistage panel and base concrete, reduce or avoid the situation that panel comes to nothing and produce, simultaneously for being in the milk operation platform is provided in the later stage panel position of coming to nothing.Meanwhile, segmentation panel all has concrete foundation separately, has greatly improved the work stress of panel, thereby has solved the problem that panel fractures and comes to nothing.

Detailed description of the invention
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, the high rock multistage of one described in the utility model panel construction, mainly formed by concrete slab and base concrete (or concrete toe board), be equipped with the Transition Materials 5 of 1～3m thickness in base concrete and rockfill connecting part, between Transition Materials 5 and concrete slab, be provided with padding layer 4, described base concrete is 2～5 layers, by this base concrete, the concrete slab of high rock is divided into multistage, and every section is highly less than 200m.Adopt the technical program, utilize 2～5 layers of base concrete (concrete toe board) that the panel of superelevation rock is carried out to segmentation, every section high is controlled in 200m, every section of panel top 5～10m scope panel is constructed before its whole panel construction end or retaining, and total height of dam is controlled in 350m.Thereby reduce or avoid the situation that concrete slab comes to nothing to produce, simultaneously for being in the milk operation platform is provided in the later stage panel position of coming to nothing.Meanwhile, segmentation panel all has concrete foundation separately, has greatly improved the work stress of panel.
