Description
Technical field
The utility model is related to hydro science dam field of engineering technology, more particularly to a kind of arch duplex panel heap
Masonry dam.
Background technology
Face dam dam type because with to Dam Site topographic and geologic condition strong adaptability, good economy performance, it is safe and reliable the characteristics of,
It is rapidly developed in China, but the high face dam in part built in recent years occurs in that dam deformation is bigger than predicted value, panel
The problems such as there is extruding destruction, crack, big embankment seepage amount.These problems are attributed to three aspects：One is that dam deformation is big；Two are
The seepage control system such as panel destructible, destruction cause embankment seepage amount big, it is understood that there may be the potential safety hazard of seepage stability；Three be to tie up
Repairing property is poor, and lower panels maintenance is difficult, runs into extreme operating condition problem and more protrudes.Thus at present to 250m grades or higher of panel
The security presence on dam is queried.
As China's economic development and the public, government significantly improve to safety requirements, to large and medium water power station engineering
Water retaining structure proposes the requirement that the extreme operating conditions such as macroseism are not fallen, design conditions can be used normally after repairing.The built 70m of China
The high face dam of the above does not overhaul the condition of base impervious system all.The presence of these problems, constrains the country to building 250
The decision-making of ~ 300m ultra-high concrete panel rock-fill dams.
During usual high face dam or superelevation face dam design, mostly from dam zoning, fill standard, joint seal, construction
Studied in terms of step, propose reduction dam deformation, improve panel stress and the related measure of control joint displacement.But these
Measure all can not more effectively solve the technical problem present in superelevation rock at present.
Utility model content
In order to overcome in the prior art high face dam panel it is long, deform it is larger；Maintenanceability is poor, and lower panels maintenance is tired
Difficult defect, the purpose of this utility model is to propose a kind of arch duplex rock, by face dam bottom
Concrete arch dam is set, the maintenanceability of profundal zone panel is improved so as to reach, improves superelevation rock panel stress
Deformation and the purpose of dam deformation.
To realize above-mentioned technical purpose, the utility model, which is adopted the following technical scheme that, to be achieved:
A kind of arch duplex rock, including concrete slab, the bed course set gradually by upstream to downstream
Material, upper Transition Materials, upstream rockfill area, downstream rockfill area；In the concrete slab bottom, concrete arch dam is set；It is described mixed
The upstream side of solidifying soil arch dam is provided with Gai Chong areas；The downstream of the concrete arch dam is upstream rockfill area.
It is preferred that, the concrete arch dam is in the horizontal plane in the arch for being convex to upstream.
It is preferred that, the concrete arch height of dam degree is less than 100m.
It is preferred that, the concrete arch dam is internally provided with monitoring maintenance gallery.
It is preferred that, the arch abutment of the concrete arch dam is located on the basis of two sides.
It is preferred that, the concrete arch dam downstream is additionally provided with lower Transition Materials；The lower Transition Materials are located at the coagulation
Between native arch dam and the upstream rockfill area.
It is preferred that, the upper Transition Materials are connected with the lower Transition Materials.
The beneficial effects of the utility model：
The utility model is additionally arranged positioned at riverbed position concrete slab upstream side on the basis of conventional concrete panel
Concrete arch dam, instead of profundal zone panel, reduce panel length, and instead of part stockpile, so as to improve depth
Maintenanceability, improvement superelevation rock stress and deformations of concrete face slab and the dam deformation of pool panel, are high face dam or super
The construction of high face dam provides foundation, especially 300m grade high CFRD；Development for superelevation face dam provides support,
Promote ultra-high concrete panel rock-fill dams technological progress, be that the research of superelevation dam is accumulated experience.
