The utility model relates to an upstream bedding structure of a concrete face rockfill dam. The purpose of this utility model is to provide an upstream pavement structure of a concrete face rockfill dam with simple structure and convenient construction, so as to provide a face pressure that does not hinder the free deformation of the face plate, reduces damage to the surface water stop, and at the same time can Taking into account the later construction of the silt bedding upstream of the dam. The technical scheme of the utility model is: an upstream pavement structure of a concrete face rockfill dam, a concrete face is poured on the upstream face of the face face rockfill dam, and a concrete toe board is built at the bottom of the concrete face, which is characterized in that it is close to the concrete face The panel weight block is built, and the panel weight block is a straw bag with silt inside. The straw bag stack formed by the straw bag is covered with silt bedding to the designed section, and the silt bedding is covered with gravel for protection. The utility model is suitable for water conservancy and hydropower projects.
Description
Technical field
The utility model relates to a kind of upstream apron structure of Concrete Face Rockfill Dam.Be applicable to Hydraulic and Hydro-Power Engineering.
Background technology
In the construction period of rock, big or the level of tail water is higher when the upstream excavation of foundation pit degree of depth, can form reverse head, act on completed bed course, upstream Gu Po and the concrete slab.For this reason, the reverse drainage pipe is buried at the toe board position of being everlasting in the engineering underground, and the panel concrete saddle weight is set, and to guarantee that reservoir level holds to certain water level the situations such as bed course appears in reverse seepage pressure and solid slope is destroyed, panel crack because of bearing does not take place.
Yet the concrete saddle weight is the rigidity saddle weight, has hindered the Free Transform (all side seams are set between panel and the toe board, and saddle weight strides across all side seams and is pressed on the panel) of panel to a certain extent, and counter plate is stressed unfavorable.Simultaneously, saddle weight is pressed on the surface flexible sealing of all side seams, may destroy the complete surperficial water-stopping system of original sealing.
Summary of the invention
The technical problems to be solved in the utility model is: at the problem of above-mentioned existence, a kind of upstream apron structure of Concrete Face Rockfill Dam of simple in structure, easy construction is provided, so that a kind of panel ballast to be provided, do not hinder the panel Free Transform, minimizing can take into account the construction of later stage dam upstream silt bedding simultaneously again to the infringement of surperficial sealing.
The technical scheme that the utility model adopted is: a kind of upstream apron structure of Concrete Face Rockfill Dam, built concrete slab at the rock upstream face, the concrete toe board has been built in this concrete slab bottom, it is characterized in that: be close to the concrete slab base and build the panel saddle weight, described panel saddle weight is the straw bag of interior dress silt, cover the silt bedding to design section above the straw bag heap that straw bag is built, cover the rock ballast mask on the silt bedding.
The base of described straw bag heap is built and highly is 5m ~ 30m.
Described straw bag heap up stream slope is than being 1:2.0 ~ 1:2.5.
The beneficial effects of the utility model are: the straw bag of dress silt can not hinder the Free Transform of concrete slab as ballast in 1, using, and is less for the infringement of the flexible sealing of peripheral seam surface yet.2, after the shutoff of reverse drainage pipe is finished, straw bag need not be removed, above directly cover the silt bedding to design section, the silt straw bag that has filled is held concurrently and is used as upstream apron, considers that straw bag is an organic material, can rot very soon behind the reservoir filling, under the deadweight effect, the inside and outside silt of bag can fuse, when panel or structural joint etc. is located to produce seepage, the silt material can stop up seepage place, thereby reaches the order of restriction seepage flow.3, simple in structure, easy construction of the utility model and engineering cost are lower.
Description of drawings
Fig. 1 is a generalized section of the present utility model.
The specific embodiment
As shown in Figure 1, present embodiment is a kind of upstream apron structure of Concrete Face Rockfill Dam, this rock upstream side is piled successively from the inside to the outside and is built the main enrockment bed of material 6, the transition bed of material 4 and the bed course bed of material 3, and wherein the bed course bed of material 3 belows are also piled and built the special bed course bed of material 5.The bed course bed of material 3 and the special bed course bed of material 5 surperficial concreting panels 1, concrete slab lower end concreting toe board 2.In this example, in the riverbed lower position uses the straw bag 7 of dress silt as the panel ballast build build concrete slab 1 and concrete toe board 2 to 5m ~ 30m highly, the up stream slope ratio can adopt 1:2.0 ~ 1:2.5.Height is built at concrete base and the up stream slope ratio can be determined according to possible reverse head estimation.
In the present embodiment, on the straw bag heap that straw bag 7 is built, cover silt bedding layer 8, cover rock ballast mask 10 on the silt bedding layer 8 to design section.
The concrete job practices of present embodiment is as follows:
1, concrete slab 1 is built and is finished, after concrete slab 1 and concrete toe board 2 constructional deficiencies finish dealing with, do not have rainfall in nearly 5 days the suitable opportunity under the reservoir before the lock retaining, and reverse drainage pipe displacement does not have under the situation of increase, implements the shutoff of reverse drainage pipe;
2, draw water and reduce water level in the toe board foundation ditch to the 2 end face exposures of concrete toe board, the straw bag 7 of dress silt is built to certain elevation as concrete slab 1 ballast base in use the gutter both sides then;
3, implement the shutoff of reverse drainage pipe;
4, treat that blocking concrete reaches design strength after, fill concrete slab 1 upstream silt bedding to design section, and cover rock ballast mask 10.
Claims (3)
