The problems such as masonry dam occurs in that dam deformation than calculating bigger than normal, face slab rupture, panel crack, especially panel maintenanceability
Difference, lower panels maintenance are difficult, run into extreme operating condition problem and more project.
At present, the main design thought of high dam concrete slab is still and arranges pressure slope body counter plate in upstream to be protected by,
Ensure to be former in the range of the depth capacity of diver's underwater operation 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 but possess maintenance condition, once go wrong it is difficult in time
Maintenance and recovery.Particularly the country has occurred and that the panel damage of individual concrete rock loam bedding bottom at present,
Cannot overhaul, reservoir can only be vented, excavate loam bedding, repair concrete slab again, cause huge loss, this tired
It is difficult that border causes the propulsion of superelevation rock to produce some.How to make panel possess maintenanceability becomes the key of problem.
Content of the invention
Technical problem to be solved in the utility model is that existing panel maintenanceability is poor, and lower panels maintenance is difficult, especially
It is profundal zone panel substantially without maintenance condition, the purpose of this utility model is to propose a kind of to make panel possess maintenanceability
Rock.
For realizing that above-mentioned technical purpose, the utility model are adopted the following technical scheme that and be achieved:
A kind of rock for making panel possess maintenanceability includes the concrete surface set gradually by upstream to downstream
Plate, bedding material, Transition Materials, upstream rockfill area, downstream rockfill area, arrange concrete patch in the lower end of concrete slab upstream side
Slope, and the lower surface for pasting slope in concrete arranges concrete slab base, inside concrete patch slope arranges grouting monitoring gallery；Institute
Concrete patch slope up stream slope ratio is stated with downstream slope than consistent, 1 is：S, and the span of s is 1.3～1.6.
Preferably, the concrete patch slope thickness is 0.05～0.1 times of head.
Preferably, multilayer grouting monitoring gallery, multilayer grouting monitoring gallery edge can be set inside 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 the concrete patch slope, the position of corresponding gallery is provided with thickened area.
Preferably, the top surface of the thickened area arranges triangularity, arc, trapezoidal or rectangle.
Preferably, state lower edge in grouting monitoring gallery and open up downwards gutter.
The beneficial effects of the utility model：
The utility model arranges concrete patch slope in the bottom of rock, in concrete patch slope arranges grouting monitoring
Gallery, by being in the milk, monitoring gallery can be monitored situations such as concrete dam Foundation Anti-seepage, deformation, and can occur splitting on concrete patch slope
When seam, carry out, in gallery, the measure of being in the milk etc. in time so that rock lower panel can be keeped in repair.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Embodiment 1
In order to overcome existing panel maintenanceability poor, lower panels maintenance is difficult, and especially profundal zone panel is substantially without inspection
The defect of condition is repaiied, the utility model provides a kind of panel enrockment for making panel possess maintenanceability as depicted in figs. 1 and 2
Dam, concrete slab 4 that the rock includes being set gradually by upstream to downstream, bedding material 5, Transition Materials 6, upstream enrockment
Area 7, downstream rockfill area 8, it is characterised in that：In the lower end of 4 upstream side of concrete slab, concrete patch slope 2 is set, and in coagulation
The lower surface on soil patch slope 2 arranges concrete slab base 3, arranges grouting monitoring gallery 1 inside concrete patch 2.
The utility model arranges concrete patch slope 2 in the bottom of rock, in concrete patch slope 2 arranges grouting prison
Gallery 1 is surveyed, and monitoring gallery 1 can be monitored situations such as concrete dam Foundation Anti-seepage, deformation by being in the milk, and slope 2 can be pasted in concrete
When there is crack, carry out, in gallery, the measure of being in the milk etc. in time so that rock lower panel can be keeped in repair.
Embodiment 2
On the basis of embodiment 1, concrete pastes 2 up stream slope ratio of slope with downstream slope than consistent, is 1：S, and the value of s
Scope is 1.3～1.6.Such ratio can fully meet the requirement for reducing ess-strain, while construction cost is not high yet, work
Phase is also relatively short.
In order to meet the requirement of antiseepage, it is ensured that do not destroyed by osmotic pressure, concrete patch 2 thickness of slope is 0.05～0.1 times
Head.
Paste in the concrete and multilayer grouting monitoring gallery 1 can be set inside slope 2, multilayer 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 multilayer filling
Slurry monitoring gallery 1, convenient to can the whole of concrete dam be highly monitored, once monitoring range is wider, and wherein one layer
When gallery fails, the presence of other gallerys does not affect to monitor.
As shown in figure 3, in order to meet the anti-requirement for blending ess-strain, on the concrete patch slope 2 position of corresponding gallery
Thickened area 9 is installed, other positions can not be thickeied, material-saving.
As shown in figure 3, the top surface of the thickened area 9 can be set to triangle, arc, trapezoidal or rectangle.It is arranged to
Triangle, convenient construction；Arc is set, and trapezoidal or rectangle, convenient compacting, shape can be constructed according to actual conditions.
As shown in figure 4, described grouting monitoring gallery 1 in lower edge open up downwards gutter, it is ensured that the traffic of gallery 1 and
Drainage.Above-mentioned gutter can adopt the structures such as groove, and big gap structure form may also be employed.
Embodiment 3
In order to overcome existing panel maintenanceability poor, lower panels maintenance is difficult, and especially profundal zone panel is substantially without inspection
The defect of condition is repaiied, the utility model provides a kind of method for making panel possess maintenanceability, specifically：In concrete slab
