Description
Technical field
The present invention relates to hydro science dam construction technique field, be specifically related to a kind of panel heap making panel possess maintainability
Masonry dam and method.
Background technology
Rock dam type has Dam Site topographic and geologic condition strong adaptability, economic excellent, safe and reliable feature,
Being rapidly developed in China, current CFRD is built dam level and has been reached 200m (wherein water cloth a strip of land between hills dam
High 233m), the rock of several 250m～300m levels is just among design studies.But the most built 200m level panel heap
Masonry dam occurs in that dam deformation than calculating the problems, especially panel maintainability such as bigger than normal, face slab rupture, panel crack
Difference, lower panels maintenance difficulty, run into extreme operating condition problem more prominent.
At present, the main design thought of high dam concrete slab is still and arranges pressure slope body counter plate in upstream and be protected by,
Ensure in the range of the depth capacity of diver's underwater performance as former when the determination of upstream pressure slope body crest level is with dead water level
Then.Panel below pressure slope body crest level bears high water head effect and does not the most possess maintenance condition, once goes wrong and is difficult in time
Maintenance and recovery.The most domestic panel damage having occurred and that individual concrete rock loam bedding bottom,
Cannot overhaul, reservoir can only be vented, excavate loam bedding, again repair concrete slab, cause huge loss, this tired
Border makes the propelling of superelevation rock produce some difficulties.How to make panel possess maintainability and become the key of problem.
Summary of the invention

For realizing above-mentioned technical purpose, the present invention adopts the following technical scheme that and is achieved:
A kind of rock making panel possess maintainability, including the concrete surface set gradually by upstream to downstream
Plate, bedding material, Transition Materials, rockfill area, upstream, rockfill area, downstream, it is characterised in that: set in the lower end of concrete slab upstream side
Put concrete patch slope, and concrete slab base is set in the lower surface on concrete patch slope, grouting is set inside concrete patch slope
Monitoring gallery.
Preferably, described concrete patch slope up stream slope ratio is consistent with slope, downstream ratio, is 1:s, and the span of s is
1.3～1.6.
Preferably, described concrete patch slope thickness is 0.05～0.1 times of head.
Preferably, multilamellar grouting monitoring gallery, multilamellar grouting monitoring gallery edge can be set inside described concrete patch slope
Dam slope is uniformly arranged on direction
Preferably, the difference in height between every layer of gallery is 20m～40m.
Preferably, on described concrete patch slope, the position of corresponding gallery is provided with thickened area.
Preferably, the end face of described thickened area is arranged to triangle, arc, trapezoidal or rectangle.
Preferably, in stating grouting monitoring gallery, lower edge offers downwards gutter.
For realizing above-mentioned technical purpose, the present invention also provides for a kind of method making panel possess maintainability, at concrete
Concrete patch slope is set bottom panel upstream, grouting monitoring gallery is set in concrete patch slope；Grouting monitoring gallery and coagulation
Soil patch slope simultaneous construction also can pour after concrete slab downstream rockfill has filled and settled half a year more than.
Beneficial effects of the present invention:
The present invention arranges concrete patch slope in the bottom of rock, arranges grouting monitoring corridor in concrete patch slope
Road, can monitor the situations such as concrete dam Foundation Anti-seepage, deformation by grouting monitoring gallery, and crack can occur on concrete patch slope
During etc. situation, in gallery, carry out the measures such as grouting in time so that rock lower panel can be keeped in repair.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
Embodiment 1
In order to overcome existing panel maintainability poor, lower panels maintenance difficulty, especially profundal zone panel is substantially without inspection
Repairing the defect of condition, the present invention provides a kind of rock making panel possess maintainability as depicted in figs. 1 and 2, should
Concrete slab 4 that rock includes being set gradually by upstream to downstream, bedding material 5, Transition Materials 6, rockfill area, upstream 7,
Rockfill area, downstream 8, it is characterised in that: concrete patch slope 2 is set in the lower end of concrete slab 4 upstream side, and pastes at concrete
The lower surface on slope 2 arranges concrete slab base 3, arranges grouting monitoring gallery 1 inside concrete patch 2.
The present invention arranges concrete patch slope 2 in the bottom of rock, arranges grouting monitoring corridor in concrete patch slope 2
Road 1, can monitor the situations such as concrete dam Foundation Anti-seepage, deformation by grouting monitoring gallery 1, and can occur on concrete patch slope 2
During the situations such as crack, in gallery, carry out the measures such as grouting in time so that rock lower panel can be keeped in repair.
Embodiment 2
On the basis of embodiment 1, concrete patch slope 2 up stream slope ratio is consistent with slope, downstream ratio, is 1:s, and the value of s
Scope is 1.3～1.6.Such ratio can fully meet the requirement reducing ess-strain, and construction cost is the highest simultaneously, work
Phase is the most relatively short.
In order to meet the requirement of antiseepage, it is ensured that do not destroyed by osmotic pressure, concrete patch slope 2 thickness is 0.05～0.1 times
Head.
Can arrange multilamellar grouting monitoring gallery 1 inside described concrete patch slope 2, multilamellar grouting monitoring gallery 1 is along dam slope
It is uniformly arranged on direction.Difference in height between every layer of gallery is 20m～40m.General difference in height is set to 30m.It is arranged to multilamellar fill
Slurry monitoring gallery 1, it is convenient that to can the whole height of concrete dam be monitored, monitoring range is wider, and wherein one layer
When gallery lost efficacy, the existence of other gallerys does not affect monitoring.
As it is shown on figure 3, in order to meet the anti-requirement blending ess-strain, on described concrete patch slope 2 position of corresponding gallery
Having installed thickened area 9, other positions can not thicken, and saves material.
As it is shown on figure 3, the end face of described thickened area 9 can be set to triangle, arc, trapezoidal or rectangle.It is arranged to
Triangle, convenient construction；Arranging arc, trapezoidal or rectangle, convenient compacting, shape can be constructed according to practical situation.
As shown in Figure 4, described grouting monitoring gallery 1 in lower edge offer downwards gutter, it is ensured that the traffic of gallery 1 and
Drainage.Above-mentioned gutter can use the structures such as groove, it is possible to uses big gap structure form.
Embodiment 3
In order to overcome existing panel maintainability poor, lower panels maintenance difficulty, especially profundal zone panel is substantially without inspection
Repair the defect of condition, the invention provides a kind of method making panel possess maintainability, specifically: on concrete slab 4
Concrete patch slope 2 is set bottom trip, grouting monitoring gallery 1 is set in concrete patch slope 2；Grouting monitoring gallery 1 and concrete
Patch slope 2 simultaneous construction also can pour after concrete slab 4 downstream rockfill has filled and settled half a year more than.
The present invention arranges concrete patch slope 2 bottom concrete slab 4 upstream, arranges grouting prison in concrete patch slope 2
Survey gallery 1, the situations such as concrete dam Foundation Anti-seepage, deformation can be monitored by grouting monitoring gallery 1, and slope 2 can be pasted at concrete
When the situations such as crack occur, in gallery, carry out the measures such as grouting in time so that rock lower panel can be keeped in repair.
Obviously, those skilled in the art can carry out various change and the modification essence without deviating from the present invention to the present invention
God and scope.So, if these amendments of the present invention and modification belong to the scope of the claims in the present invention and equivalent technologies thereof
Within, then the present invention is also intended to comprise these change and modification.
