Description
Technical field
The present invention relates to buildings waterproof field, specifically, relate to a kind of waterproof structure of concrete face rockfill dam joint and construction technology.
Background technology
CFRD has become universally acknowledged a kind of both economical applicable dam type.It is suitable for various topographic and geologic condition, easy construction, and filling material can be gathered materials on the spot, and all kinds of pledge excavation material can use by subregion, and construction machinery is more single, and construction interference is few, and progress is fast.In China, although the employing of this dam type is started late, but development speed is very fast, and the sealing of the sealing of dam, especially slab joint is one of key issue in engineering, concerning safety, service life and the economical operation of dam.
The conventional water-proof scheme of CFRD generally uses three road measures of preventing water: as shown in Figure 1, topmost top layer plasticity caulking material 20 is set, and using GB composite cover 21 that plasticity caulking material 20 is closed, outermost layer is attached most importance to sandy loam spontaneous recovery filler 12；Second measures of preventing water is angle steel 17 pre-buried in panel 11, toe board 10 and rubber fastening band 19 is fixed on sealing position by bolt 18, rely on the pressure compacting rubber fastening band 19 of bolt 18, angle steel 17, rubber fastening band 19 both wings are pressed on the pre-buried angle steel 17 of panel 11, block water seepage, and rubber bar 16 is set, support rubber fastening band 19；3rd road measures of preventing water uses metallic water stop tie 14, and metallic water stop tie 14 both wings are embedded in the bottom of panel 11 and toe board 10, and irrigate pointing 15 in filleting, are provided with filler 13 in the outside of metallic water stop tie 14, and the outside of filler 13 is provided with GB composite cover 21.This water proof structure is referred to as GB Novel water-stop structural shape, has been obtained for national inventing patent (ZL99127395.8) and China Power science and technology third prize.
But, this seam waterproof structure has the disadvantage in that (1) pre-buried angle steel 17 and concrete are the most bonding, there is seepage gap between the two；(2) there is gap between bolt 18 and concrete；(3) rubber fastening band 19 is under long compressive, stress relaxation, elastic reduction, and resilience reduces；(4) rubber fastening band 19 pressure experienced is uneven, is under pressure greatly near the place of bolt 18, and the place remote apart from bolt 18 is under pressure little；(5) when rubber fastening band 19 needs docking, T-shaped, cross overlap joint, being limited by on-the-spot execution conditions institute, joint quality of connection is affected.Therefore the reliability of this water proof structure is the highest, infiltration, seepy question easily occurs.
Summary of the invention
The technical problem to be solved in the present invention is to overcome drawbacks described above, it is provided that a kind of reliability height, the waterproof structure of concrete face rockfill dam joint of good water-proof effect and construction technology.
For solving the problems referred to above, the technical solution adopted in the present invention is:

As further improving:
Described protection device is to be fixedly installed on the metal protection cover plate that U-shaped supporting plate is peripheral.
Described metal protection cover plate is fixed on concrete body by expansion bolt.
As further improving:
It is provided with pointing between described F type copper waterstop and U-shaped supporting plate.
Water proof structure of the present invention retains in former technique; copper waterstop and pointing process portion; and upstream face is installed surface layer protection baffle plate technique by installing U-shaped supporting plate both sides fluting encapsulating bonding two-layer waterproof roll; traditional " seamed waterproof " is changed into " seamless waterproof "; the water proof structure of optimised coagulation soil rock seam, improves seam waterproof reliability and durability.
The construction technology of a kind of waterproof structure of concrete face rockfill dam joint, it is characterised in that described processing step is:
A, in seamTopThe U-shaped supporting plate that thickness is 2 is set, and fixes with expansion bolt；
B, open on the top of concrete body and cut open groove, and pour into binding agent；
C, 1.5 waterproof rolls are set in the periphery of U-shaped supporting plate, the end of waterproof roll is put in groove；
D, sealing coat is set in the periphery of waterproof roll, and is fixed on concrete body with expansion bolt；
E, metal protection cover plate is set in the periphery of sealing coat, and metal protection cover plate is fixed on concrete body by logical expanded bolt.
Owing to have employed technique scheme, this invention simplifies original loaded down with trivial details construction technology, save material cost and cost of labor, substantially increase the reliability of seam waterproof, compared with traditional method, simplify structure, easy construction, reduces cost, checks and method for maintaining is simple, there is preferable practicality, for innovative technology.
The present invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
