Abstract
The utility model discloses a dam crest wave wall structure of an earth and rockfill dam, comprising a dam body lifting part, a wave wall and a protective barrier, wherein the dam body lifting part is arranged on the top of the dam body of the earth and rockfill dam under the condition that the original designed altitude of the top of the wave wall maintains unchanged; the dam body lifting part has the height of 0.5 m to 1.2 m; the wave wall is arranged at the upstream side of the dam crest of the earth and rockfill dam; the top of the conventional wave wall is completely buried in the dam body or is only exposed partially by lifting the dam crest of the earth and rockfill dam; the top of the wave wall is 0.7 m to 0 m higher than the dam body lifting part; and the protective barrier is arranged on the top of the wave wall and has the height of 0.3 m to 1.2 m. Due to the gap of the protective barrier, patrol and overhaul of the upstream dam surface are facilitated; the dam crest of the earth and rockfill dam is lifted, so engineering excavation slag can be utilized completely and environmental protection is promoted; and the protective barrier harmonious with the dam scenery is arranged at the upper part of the wave wall, therefore, the model is beautiful.
Description
Technical field
The utility model relates to Hydraulic and Hydro-Power Engineering water retaining structure field, relates in particular to a kind of earth and rockfill dam dam crest wave wall structure.
Background technology
Standards such as rolling earth-rock dam, rock, concrete gravity dam, arched concrete dam all require at present: should concrete wave screen be set at the dam crest upstream side, the wall top generally exceeds dam crest 1.0m～1.2m.Engineering application also is like this.But the continuous concrete wave screen of dam crest upstream side is higher, and texture is thick and heavy, and it is attractive in appearance that moulding is owed, and is difficult to coordinate with dam district landscape, and both block vision of entity structure simultaneously is not easy to the inspection and the maintenance of upstream dam facing again.For earth and rockfill dam, crest elevation causes more engineering excavation to abandon material because of the wave wall setting reduces the minimizing that then means the dam embankment material, is unfavorable for environmental protection.
The utility model content
The purpose of this utility model is to provide a kind of and makes things convenient for inspection of upstream dam facing and maintenance, can utilize the engineering excavation slag charge more, helps environmental protection, and earth and rockfill dam dam crest wave wall structure handsome in appearance, thereby solves the foregoing problems that exists in the prior art.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of earth and rockfill dam dam crest wave wall structure comprises that dam body raises part, wave wall and guard rail; Described dam body is raised the top that part is arranged at the earth and rockfill dam dam body, and the height that described dam body is raised part is 0.5m～1.2m; Described wave wall is arranged at the dam crest upstream side of earth and rockfill dam, and the wall of described wave wall is risen out top 0.7m～0m that described dam body is raised part; Described guard rail is arranged at the wall top of described wave wall, and the height of described guard rail is 0.3m～1.2m.
Preferably, the wall of described wave wall top adds up to 1.0m～1.2m with the difference in height of the dam crest of earth and rockfill dam and the height of described guard rail, and the height of wherein said guard rail is the height that described dam body is raised part.
The beneficial effects of the utility model are:
(1) inspection and the maintenance of upstream dam facing is convenient in guard rail of the present utility model space; (2) raise the earth and rockfill dam dam crest dam embankment material is increased, can utilize the engineering excavation slag charge more, be beneficial to environmental protection; (3) wave wall wall top flushes or the part exposure with dam crest, and top adds the guard rail of coordinating with dam district landscape, and is handsome in appearance.
Description of drawings
Fig. 1 is the schematic diagram of earth and rockfill dam dam crest wave wall structure of the present utility model;
Wherein: the 1---wave wall; The 2---dam body is raised part; The 3---guard rail.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.Should be appreciated that the specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, the utility model discloses a kind of earth and rockfill dam dam crest wave wall structure, comprise that dam body raises part, wave wall and guard rail; Keeping wave wall to push up under the constant situation of original design altitude, described dam body is raised the top that part is arranged at the earth and rockfill dam dam body, and the height that described dam body is raised part is 0.5m～1.2m; Described wave wall is arranged at the dam crest upstream side of earth and rockfill dam, and dam body or only exposure part are all imbedded by raising the earth and rockfill dam dam crest in conventional wave wall wall top, and the wall of described wave wall is risen out top 0.7m～0m that described dam body is raised part; Described guard rail is arranged at the wall top of described wave wall, and the height of described guard rail is 0.3m～1.2m.Described guard rail can be materials such as steel, stone matter, precast concrete.Wall top and the difference in height of the dam crest of earth and rockfill dam and the height of described guard rail of described wave wall add up to 1.0m～1.2m, and the height of wherein said guard rail is the height that described dam body is raised part.The technical solution of the utility model is also applicable to water-retaining structures such as all dam types such as gravity dam, arch dam and dykes.
Below to adopt the technical solution of the utility model with certain pumped storage power plant upper storage reservoir reinforced concrete face rockfill dam be that example is described with reference to the accompanying drawings: the wide 8m of dam crest, the long 655m of dam crest, maximum height of dam 64.5m.Keep wave wall 1 wall top design altitude 175.1m constant, crest elevation is raised to 174.5m, dam body is raised part 2 and highly is 0.6m, and wave wall 1 wall is risen out dam crest 0.6m, and top adds the high white lacquer precast concrete railing 3 of 0.6m.
By adopting the disclosed technique scheme of the utility model, obtained following useful effect:
(1) inspection and the maintenance of loose rock dam upstream panel is convenient in guard rail of the present utility model space; (2) dam embankment utilizes about 3200m more
3The underground cavern excavation slag charge, be beneficial to the environmental protection in engineering district greatly; (3) wave wall wall top portion exposure, top add white lacquer precast concrete guard rail, combine together with upper storage reservoir building and landscape, and be handsome in appearance.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be looked protection domain of the present utility model.
