Abstract
The utility model relates to a watertight structure for a surface layer of a loose rock dam of a concrete slab in hydraulic and hydro-power engineering, which comprises a plastic sealing material, a supporting element, a protective element and a sealing element. The watertight structure is characterized in that the plastic sealing material is arranged on the surface layers of the slab and a toe board; the supporting element for supporting the plastic sealing material is arranged at the bottom of the plastic sealing material; the supporting element is provided with the sealing element with sealing function; and a layer of cover plate with protective function is arranged on the plastic sealing material. The sealing element is a rubber water stopper or a plastic water stopper, and the edges on the two sides of the sealing element are distributed with through holes. The supporting element is a plastic rod or a rubber rod, and the diameter of the plastic rod or the rubber rod is greater than the distance between seams. The utility model has the advantages that different watertight mechanisms and structures are adopted with better watertight effect, the engineering quality is high and the service life is long.
Description
Technical field
The utility model relates to the water-stopping structure on the top layer of Concrete Face Rockfill Dam in a kind of water conservancy and hydropower construction.
Background technology
The existing concrete rock is with its safety, economic and construct fast that characteristics just worldwide obtain increasing the employing, this kind dam type water-stopping structure, sealing performance good, badly directly have influence on dam and can normally move.According to operation characteristic separately, the seam of Concrete Face Rockfill Dam can be divided into three types of all side seams, stretch-draw seam, tension seams, and wherein the poorest with the service condition of all side seams, it also is paid close attention to by the designer.In all side seams,, adopt three road sealing modes usually from top to bottom, be exactly top layer, middle level, bottom sealing, wherein surface watertight seal is again with the extremely people's attention of its outstanding status.
At present, it is the sealing mode of core that surface watertight seal adopts usually with plasticity caulking materials such as GB, SR, IGAS, conventional water-stopping method then is the measure of taking various materials and configuration aspects, plastic materials such as GB, SR, IGAS are opened in the process in seam, can under the effect of water pressure, flow into and become silted up and fill out open seam, reach the purpose of sealing with this.The structure that adopts then is to be provided with plasticity caulking materials such as GB, SR, IGAS on the top layer of panel and toe board, and cover sheet is set on the surface, and part also is provided with baffle in the bottom.This structure easily causes seam to be pierced through by press water, occurs cellularly, and stagnant water effect is bad.
The utility model content
The utility model aims to provide a kind of brand-new water-stopping structure of better effects if.Its technical scheme that adopts is: the water seepage prevention structure in a kind of Hydraulic and Hydro-Power Engineering; comprise plasticity caulking material, support component, protecting component and potted component; it is characterized in that; be provided with the plasticity caulking material on panel, toe board top layer; plasticity caulking material bottom is provided with its passive support component; support component is provided with the potted component that seals, and the surface of plasticity caulking material then is provided with one deck protecting component.
Wherein, protecting component is a cover plate, and cover plate is located at plasticity caulking material surface.Potted component is rubber fastening band or plastics waterstop, and its both sides of the edge are distributed with uniform through hole.Support component is sticking plaster or rubber bar, the diameter of sticking plaster or rubber bar greater than spacing of joints from.
The beneficial effects of the utility model are: adopt different sealing mechanism, structure, its stagnant water effect is better, workmanship height, long service life.
Description of drawings
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation;
Fig. 3 is a sealing band structure schematic diagram in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done more detailed description.
Consult Fig. 1, Fig. 3, existing water-stopping structure is provided with cover sheet 1 for the top layer at panel 5 and toe board 4 is provided with plasticity caulking materials 6 such as GB, SR, IGAS on its surface, be provided with in the bottom to make plastic material 6 mobile stable baffles 3.This structure easily causes seam to be pierced through by press water, occurs cellularly, and stagnant water effect is bad.
Consult Fig. 2, water seepage prevention structure of the present utility model comprises plasticity caulking material 6, support component 3, protecting component 1 and potted component 2.At first be provided with plasticity caulking materials 6 such as GB, SR, IGAS at peripheral seam surface, then be provided with its passive sticking plaster or rubber bar 3 in plasticity caulking material 6 bottoms such as GB, SR, IGAS, sticking plaster or rubber bar 3 are provided with rubber fastening band or the plastics waterstop 2 that plasticity caulking material 6 is sealed, and its both sides of the edge are distributed with uniform through hole.At last, the surface cover upper cover plate 1 at plasticity caulking materials 6 such as GB, SR, IGAS can play a protective role to the plasticity calking compound 6 of flexibility.
In addition, in order to realize the sealing mechanism of said structure form, the rubber or the sticking plaster 3 of plasticity caulking material 6 bottoms such as GB, SR, IGAS should possess enough big diameter on the one hand, to guarantee when seam 7 is opened, can resist the effect of water pressure, make rubber bar or sticking plaster 3 not be pressed in the seam 7.On the other hand, rubber fastening band or plastics waterstop 2 can adapt to the effect of water pressure and seam 7 displacements, with the validity of guaranteeing to seal.Wherein rubber fastening band and plastics waterstop 2 general undulates, the number of wave should reduce as far as possible, to satisfy because seam 7 is drawn the stress that moves and produce in waterstop 2.
During construction, earlier support component 3 is placed on seam 7 tops, above seam 7, preset angle steel or channel-section steel 8 in the concrete of both sides, panel 5 and toe board 4, and punching is provided with set bolt 9 thereon, rubber fastening band or 2 lockings of plastics waterstop is fixed on angle steel or the channel-section steel 8 with nut.Then plasticity caulking material 6 is filled on waterstop 2, and between panel 5 and toe board 4, at last cover sheet 1 is covered on plastic material 6, and cover plate 1 covered both sides lockings is fixed on i.e. completion on panel 5 and the toe board 4.
