Description
Technical field
A kind of impervious watertight structure is the utility model is related to, more particularly to a kind of antiseepage in Hydraulic and Hydro-Power Engineering stops
Water-bound.
Background technology
Devoting Major Efforts To Developing hydraulic power potentials is the important energy strategy developing policy in current China.Dam is built using local material
Construction it is with a long history, have gather materials on the spot, be low to geological conditions requirement, the advantage such as easy construction, low cost, oneself is extensive
Using, and with abundant design, construction and operational management experience.
At present, local material dam generally use clay homogeneous dam, calculous soil core-wall (sloping core) rock-fill dams, concrete surface sheetpile
The patterns such as masonry dam, pitch core-wall (sloping core) rock-fill dams, it is the first choice of Hydropower Dam design selection, is widely used, it is also very classical.
Generally, the antiseepage of dam includes Foundation Anti-seepage and dam body seepage.Foundation Anti-seepage is typically the combination in the bottom of dam body and the dam foundation
Position is provided with Foundation Anti-seepage facility, concrete of the Foundation Anti-seepage facility generally by being directly built on the basis of batholith or coating
Connecting plate, concrete pedestal or concrete toe board etc. and its it is arranged on concrete connecting plate, concrete pedestal or concrete toe board
The cut-pff wall and grouting body of bottom are formed;The antiseepage of dam body is typically to set face slab for water retaining on the upstream face of dam body.Work as use
When calculous soil core-wall (sloping core) builds high dam, the impervious material dosage required for its panel is big, and haul distance is remote, and its quality also tends to full
Foot not requirements of building a dam, blending technique is not only complicated, is also required to the place of certain area, impermeable soil is explored, experimental study
Time it is also long, building a dam to fetch earth also tends to cause to plough occupied, involves and largely migrates and be related to soil erosion, to a certain extent
Hydroelectric development process is delayed;During using being built a dam on local material basement rock, often prioritizing selection CFRD will
After concrete rigid plate is placed in the antiseepage for being used as whole dam body on dam body upstream face, but dam embankment is highly more than 200m, by
It is larger in the deflection of the rockfill under water pressure and self-gravity action, periphery fissure waterstop and panel crack often turn into design,
The maximum hidden danger of operation, and the shadow that crack caused by order to reduce the inhomogeneous deformation of dam body enrockment sedimentation etc. is run to dam body
Ring, it is necessary to which in dam body enrockment completion relief, its natural subsidence just can further be constructed after for a period of time, so as to extend
Build the dam cycle.The widely used calculous soil material of Rockfill Dam impervious material, concrete slab, bituminous concrete, geomembrane, geotechnique
Plant etc., builds that the impervious material of high rock-fill dams selection is limited, and the stress of cut-pff wall can not use existing theory on deep covering layer
It is accurate to calculate, it is high to material requirements, influenceed by construction speed arrangement, cut-pff wall and core-wall joints structure form are used and needed
Research and the new problem solved.A kind of therefore, it is proposed that impervious watertight structure in Hydraulic and Hydro-Power Engineering.
