Abstract
The utility model discloses a protective device for a copper water stop of a peripheral crack of a face rock-fill dam, which comprises a toe board, a lower layer sand bag, an upper layer sand bag and the copper water stop, wherein the copper water stop comprises flanges and a nose; one end of the copper water stop is fixed in the toe board; and the end at which a U-shaped groove is formed by the flanges and the nose is exposed on the surface of the toe board. The protective device for the copper water stop of the peripheral crack of the face rock-fill dam, which is disclosed by the utility model, is simple to manufacture and convenient to construct, little material is consumed, the cost is low, the copper water stop can be effectively protected and can be avoided from being deformed and damaged, so the seepage-proofing function of the copper water stop is fully performed, and the service life is long.
Description
Technical field
The utility model relates to the protective device of all side seam Copper water stops of a kind of rock, belongs to Copper water stop resist technology field.
Background technology
At present, Concrete Face Rockfill Dam all has Copper water stop at the toe board concrete of all side seams with the design of panel concrete middle part, this is the important antiseepage barrier together of panel, the existing copper sealing be shaped as " UU " shape that two " U " link together, the centre is an one, the centre is the nose of Copper water stop, and the both sides that bend up are the Copper water stop edge of a wing, and the effect on two edges of a wing mainly is to guarantee that Copper water stop is connected with concrete.Elder generation's construction toe board when construction, a side of Copper water stop is embedded in earlier in the toe board concrete, just imbeds in the concrete when relative opposite side is treated the working face board concrete, generally longer during this period of time, during, a variety of causes can cause Copper water stop to damage, thereby influence antiseepage, and increase maintenance cost; In addition,, easily make the Copper water stop distortion, therefore, if protection is improper, the antiseepage effect of the whole seepage prevention system of influence is brought into play during the application of Copper water stop because of polluted water mud ash is heavier.
In the prior art, the most tub or cans of customization of adopting are protected Copper water stop, mainly are that tub or can are fixed on the toe board, and Copper water stop is sequestered in wherein.This kind equipment can effectively be protected Copper water stop, but its consumptive material is many, and increases construction process and cost.
The utility model content
The purpose of this utility model is, at the deficiencies in the prior art, provide a kind of rock week side seam Copper water stop protective device, consumptive material is few, cost is low, is convenient to construction, and effectively avoids Copper water stop impaired, makes Copper water stop give full play to the antiseepage function.
The technical scheme that the utility model is dealt with problems is: the protective device of all side seam Copper water stops of a kind of rock; comprise toe board, lower floor's sand pocket, upper strata sand pocket, Copper water stop; described Copper water stop comprises the edge of a wing and nose; the one end is fixed in the toe board, and an end that constitutes U-lag between the edge of a wing and the nose exposes to the toe board surface.
The opening of described U-lag up and place the top of lower floor's sand pocket.
The inner plank of filling of described U-lag.
Described upper strata sand pocket places the top of Copper water stop.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model novel structure is made simple, easy construction, consumptive material is few, cost is low;
2, innovation structure of the present utility model has been protected Copper water stop effectively, makes it avoid being out of shape impaired, and can guarantee giving full play to of Copper water stop antiseepage function, and long perfomance life.
Description of drawings
Fig. 1 is the structural representation of the protective device of all side seam Copper water stops of the utility model rock.
Among the figure: 1-lower floor sand pocket, 2-Copper water stop, 3-plank, 4-upper strata sand pocket, 5-toe board, 6-U shape groove.
The specific embodiment
As shown in Figure 1; the protective device of all side seam Copper water stops of a kind of rock; comprise toe board, lower floor's sand pocket 1, upper strata sand pocket 4, Copper water stop 2; described Copper water stop 2 comprises the edge of a wing and nose (edge of a wing and nose do not indicate in the drawings); the one end is fixed in the toe board 5, and an end that constitutes U-lag 6 between the edge of a wing and the nose exposes to toe board 5 surfaces.The opening of described U-lag 6 up and place the top of lower floor's sand pocket 1.The described U-lag 6 inner planks 3 of filling.Described upper strata sand pocket 4 places the top of Copper water stop 2.
Construction at the scene, when using the utility model, at first, it is standby to install sand pocket, then, toe board 5 is set, and a side of Copper water stop 2 is embedded in the concrete of toe board 5, imbeds in the concrete again when opposite side on the other side is treated the working face board concrete; After having torn toe board 5 open mould; determine filling lower floor sand pocket according to the height between Copper water stop 2 and the base surface; make Copper water stop 2 stressed on lower floor's sand pocket 1; then plank 3 block-by-blocks are put into U-lag 6; until filling and leading up; on plank 3 and Copper water stop 2, place upper strata sand pocket 4 more at last, be subjected to external interference, play the effect of protection Copper water stop 2 to prevent Copper water stop 2.
In the foregoing description, used sand has a large amount of uses in special bedding material work progress, therefore can gather materials on the spot, and the plank 3 and the sand pocket that are provided with around the Copper water stop 2 are effectively protected Copper water stop 2.
The utility model is not limited to above-mentioned embodiment, and those of ordinary skills made to any conspicuous improvement of above-mentioned embodiment or change, can not exceed the protection domain of design of the present utility model and claims.
Claims (4)
