Description
Technical field
The technology of the present invention relates to rock, a kind of panel construction for severe cold area rock.
Background technology
The most both at home and abroad during design of face slab rockfill dam, plate thickness is typically based on " CFRD design rule
Model ", and with reference to other domestic and international project experience, use following formula to calculate:
T=0.30+0.0035H
In formula, T is plate thickness (m), and H is to calculate section to the vertical dimension (m) at panel top.
General face dam near normal pool level plate thickness at about 0.3-0.4m.According to " hydraulic structure load
Design specification ", static ice pressure standard value see table shown:
Static ice pressure standard value
| Ice layer thickness (m) | 0.4 | 0.6 | 0.8 | 1.0 | 1.2 |
| Static ice pressure standard value (kN/m) | 85 | 180 | 215 | 245 | 280 |
Severe cold area reservoir ice layer thickness is typically up to 1-1.5m, it is considered to after partial safety factor for load, and ice sheet heats up when expanding
The static ice pressure acted on unit width panel endangers following for generation up to 270-352kN, huge static ice pressure:
(1) static ice pressure directly acts on panel, concrete slab extruding will be destroyed；
(2), after panel is destroyed, the bedding material of lower panels, Transition Materials and main rockfill are also destroyed；
(3) bulwark destroys, and dash elevation reduces, and then jeopardizes dam safety.

Plate destroys and safety of dam body problem.
Accompanying drawing explanation
Fig. 1 is the structural representation of the panel for severe cold area rock of the present invention.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, the panel construction for severe cold area rock of the present invention, described panel uses bilayer mixed
Solidifying soil panel, upper strata panel can slide on lower floor's panel.
Specifically, described panel is divided into hypomere panel 1 and epimere panel, described epimere panel to be divided into upper strata slidable panels
2 and lower floor's fixed panel 3, lower floor's fixed panel 3 is integrally formed with hypomere panel 1, the surface of upper strata slidable panels 2 and hypomere face
The surface of plate 1 is equal, is provided with flat plastic sheet 7, upper and lower surface between described upper strata slidable panels 2 and lower floor's fixed panel 3
The flat plastic sheet 7 being brushed with noncongeable oil is fixed on lower floor's fixed panel 3, upper strata slidable panels 2 and hypomere panel 1 and wave resistance
Between wall 8 is arranged, twice are forever stitched, and twice are provided with water sealing structure in forever stitching.
Permanent seam between described upper strata slidable panels 2 and hypomere panel 1 is arranged on below normal pool level 2-2.5m.
The water sealing structure of the permanent seam between described upper strata slidable panels 2 and hypomere panel 1 and bulwark 8 is upper and lower two
Road sealing, arranges many noses copper sheet sealing piece 5 bottom seam, fill plastic filler 10 in seam, and seam top arranges PVC rubber bar 9, seam
Undaform rubber fastening band 4 is laid on surface, and exterior portion fills plastic filler 10, and top covers ethylene propylene diene rubber antiseepage cover plate 11.
W type copper water stop 6 it is provided with between described hypomere panel 1 and bulwark 8 base plate.
The a width of 5-10cm of seam of the permanent seam between described upper strata slidable panels 2 and hypomere panel 1, upper strata slidable panels 2
And a width of 20-30cm of seam of the permanent seam between bulwark 8.
The thickness of described upper strata slidable panels 2 is 30-40cm.
During construction, first many noses copper sheet sealing piece 5 of hypomere panel 1 and upper strata slidable panels 2, upper strata sliding surface are set
The W type Copper water stop between many noses copper sheet sealing piece 5 and lower floor's fixed panel 3 and bulwark 8 between plate 2 and bulwark 8
Sheet 6, and will seam inseam between fill plastic filler 10, after-pouring lower floor fixed panel 2, after having poured, in high-strength flat plastic
Sheet 7 two sides brush noncongeable oil, is fixed on lower floor's fixed panel 3；Set with hypomere panel 1 and bulwark 8 at upper strata slidable panels 2
Between putting, twice are forever stitched, and arrange many noses copper sheet sealing 5 bottom seam, and permanent seam stitches wide and many noses copper sheet sealing 5 ductility
Determine depending on ice layer thickness and displacement, seam in fill plastic filler 10, top sets PVC rubber bar 9, after-pouring upper strata slidable panels
2, finally at top laying undaform rubber fastening band 4, exterior portion filling plastic filler 10, ethylene propylene diene rubber antiseepage cover plate 11,
The technology of the present invention completes.
The present invention avoids owing to concrete slab extrusion shearing destroys, and then affects safety of dam body.In practice process
In, firstly, since the existence of upper strata slidable panels so that huge static ice pressure by upper strata slidable panels and hypomere panel it
Between the displacement of copper sheet sealing that arranges offset, make ice pressure be uniformly transferred on lower floor's fixed panel, significantly reduce concentration
Ice pressure, reduces the failure by shear of ice pressure counter plate；Secondly because ice pressure is uniformly transferred on lower floor's fixed panel, lower floor
Fixed panel is overall with the bedding material of its underpart, Transition Materials and main rockfill by uniform pressure, it is ensured that the safety of dam body materials；
Being protected additionally, due to panel, bedding material, Transition Materials and main rockfill, bulwark itself is also protected, it is thus possible to normally
Dash, it is ensured that the safety of dam body；Further, owing to using many noses copper sheet sealing, solve traditional panel and can not produce excessive position
The problem moved；Last due to the protective effect of movable panel itself, protect the safety of lower floor's fixed panel.In sum, originally
Invention efficiently solves severe cold area face dam panel and extrudes destruction problem because of frost, ensures that rock panel
And whole safety of dam body own.
Example described above is merely to illustrate technological thought and the feature of the present invention, its object is to those skilled in the art
Member is it will be appreciated that present disclosure implementing according to this, it is impossible to only limit the scope of the claims of the present invention with this example, the most all
