Description
Technical field
The utility model relates to a kind of high earthquake territory concrete face rockfill dam dam crest structures, are suitable for water power water conservancy work
Journey.
Background technique
In recent years, concrete face rockfill dam is because it is with good stability against sliding, good osmotic stability, warp
Ji, it is adaptable the advantages that and be widely used in water power hydraulic engineering.In high earthquake territory, concrete face rockfill dam is because of earthquake
Destroyed stop-water seriously threatens dam safety operation between panel damage caused by enrockment settles, panel and bulwark.Therefore, high earthquake
Area's concrete face rockfill dam dam crest structure designs superiority and inferiority, is related to the success or failure of engineering.
Summary of the invention
Technical problem to be solved by the utility model is: providing a kind of structure simple, easy for construction, safe and reliable highland
Earthquake region concrete face rockfill dam dam crest structure, to ensure that panel adapts to high earthquake territory Seismic Settlement to big dam facing to the maximum extent
The destruction of plate leakage preventing structure keeps leakage controllable, it is ensured that dam structure is stablized.
The technical scheme adopted by the utility model is a kind of high earthquake territory concrete face rockfill dam dam crest structure,
Be characterized in that: have dam body, upstream face, downstream face and the top surface of dam body be respectively set armored concrete panel, downstream protection slope and
Dam crest road surface, armored concrete panel top pour bulwark that is upright, being higher by dam crest road surface, bulwark and reinforced concrete
Native panel, which pours, builds up an entirety.
The dam body has stockpile and is set in turn in the Transition Materials and bedding material of stockpile upstream side.
The armored concrete below the panel is equipped with one layer and rolls mortar.
The mortar that rolls is using low-grade rolled mortar, 5~8cm of thickness.
One layer of non-fine concrete bed course is equipped with below the downstream protection slope.
The non-fine concrete bed course thickness 10cm~30cm.
The downstream protection slope embeds cemented rock or cast in place concrete plate using cemented rock slope protection or concrete frame lattice beam.
High 1.2m~the 1.6m of the bulwark wall, wall thickness 0.4m~0.6m.
Sealing is equipped in the panel construction seam of the armored concrete panel, sealing extends to following 5cm at the top of bulwark
~10cm stops.
The beneficial effects of the utility model are: 1, the utility model armored concrete panel and bulwark are done it is integral,
Avoiding structural joint sealing shake between high earthquake territory panel, bulwark and falling into destroy leads to dam body infiltration risk, improves seepage control of dam
Reliability of structure, leakage are controllable；2, the utility model adds non-fine concrete bed course in dam downstream side, protects convenient for downstream side
Slope construction, it is ensured that dam slope draining in downstream avoids dam material and is carried over, improves safety, the durability of engineering.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment.
Specific embodiment
As shown in Figure 1, the present embodiment is a kind of high earthquake territory concrete face rockfill dam dam crest structure, the Rockfill Dam
With stockpile 5,5 upstream side of stockpile is successively arranged Transition Materials 4 and bedding material 3.Upstream face, downstream face and the top surface of dam body point
Not She Zhi armored concrete panel 1, downstream protection slope 6 and dam crest road surface 8, pour at the top of armored concrete panel 1 be formed with it is upright
, the bulwark 101 for being higher by dam crest road surface 8, bulwark 101 and armored concrete panel 1, which pour, builds up an overall structure.
One layer is equipped with below armored concrete panel 1 and rolls mortar 2, for repairing Po Gupo.Downstream protection slope 6 uses and grouts block
Stone slope protection or concrete frame lattice beam embed the slope protections such as cemented rock or precast concrete block, enhance downstream dam slope stability, avoid
Tumble stone.For convenient for the construction of downstream protection slope 6, it is ensured that one layer of non-fine concrete bed course Gu Po is added in draining below downstream protection slope 6
7。
The high earthquake territory concrete face rockfill dam dam crest structure role of the present embodiment is specific as follows:
A, armored concrete panel 1: armored concrete panel 1 executes existing national standards, and " concrete face rockfill dam is set
Meter specification " (DL/T 5016) related panel construction design relevant regulations.It is made into upright wall at the top of panel, the high 1.2m~1.6m of wall,
Wall thickness 0.4m~0.6m also serves as bulwark 101, and practice of construction wall top is contemplated that beautification of landscape designs.It is set only in panel construction seam
Water, sealing, which extends to following 5cm~10cm at the top of bulwark, to be stopped.For convenient for construction, it is ensured that structure safety, highly resistance earthquake region slope
Plate top thickness preferably takes 0.4m thick, is constructed using landslide；The upright bulwark in top uses formwork erection cast-in-place construction.
B, it rolls mortar 2: using low-grade rolled mortar Gu Po, 5~8cm of thickness.
C, it bedding material 3: executes existing national standards " concrete face rockfill dam design specification " (DL/T5016).
D, it Transition Materials 4: executes existing national standards " concrete face rockfill dam design specification " (DL/T5016).
E, it stockpile 5: executes existing national standards " concrete face rockfill dam design specification " (DL/T5016)；According to work
Journey material source feature, adaptation to local conditions carry out dam body enrockment zoning design；Thin layer rolls, and improves dam rockfill anti-seismic performance.
F, downstream protection slope 6: highly resistance earthquake region dam downstream protection slope preferably uses cemented rock to design, or uses concrete frame lattice beam
The embedded forms such as cemented rock or cast in place concrete plate；Suitably slow down downstream level-one dam slope, permanent deformation, which is limited in, to be connect
By in the range of.
G, non-fine concrete bed course 7: adding one layer of non-fine concrete bed course Gu Po below downstream protection slope 6, and bed course is thick
10cm~30cm constructs convenient for downstream protection slope, it is ensured that draining.
H, dam crest road surface 8: face dam width at dam crest generally by the height on dam, dam crest structure, flood prevention management, traffic require and
The combined factors such as construction site requirement determine.High earthquake territory, width at dam crest should be designed not less than 10m；Dam crest road surface is proposed with
Asphalt concrete pavement, the wear-resisting not fugitive dust of damping noise reduction；According to requirement of engineering, the affiliated facilities such as dam crest cable duct, street lamp are added.
