Abstract
The invention relates to a steel cable dam comprising a truss structure dam body and a steel structure water retaining panel, wherein the lower end of the truss structure dam body is fixed on a dam foundation concrete bearing platform; steel cables are distributed and fixed on support nodes of the truss structure dam body, obliquely upstream pulled along an upstream direction and fixed in a rock stratum or both-bank concrete side slopes; and the truss structure dam body, the steel structure water retaining panel, the steel cables and connecting bolts are accessorily coated with anticorrosive paint polyurea materials. The steel cable dam has the advantages of simple structure, easy construction and maintenance and short construction period, has low requirements on the both-bank concrete side slopes during dam construction because the steel cables relieve the pressure born by the both-bank concrete side slope to a great degree, is suitable for various terrains, can even save the processing of bearing platforms of the both-bank concrete side slopes positioned on dam abutments and also relieve the pulling force of the truss structure dam body on a bottom bearing platform to a great degree; and in addition, the invention has the advantages of simple, stable and reliable structure, long service life and more cost reduction, and is suitable for industrialized production and field assembly implementation.
Description
Technical field
The present invention relates to the dam structure in Hydraulic and Hydro-Power Engineering field, specifically relate to a kind of cable wire dam.
Background technology
At present, there is multiple dam body in the hydrotechnics field, earth dam for example, and loose rock dam, concrete dam, arch dam, types such as steel-structure dam, all there is its unique advantage on various dams.Earth and rockfill dam expends a large amount of sandstone material, long construction period, and special release floodwatering facility and seepage control system need be set.Ordinary steel structure dam body, its origin of force normally utilizes dam base concrete cushion cap and the special constructing concrete side slope in two sides, steel work panel and trussed construction water pressure pass at the bottom of the dam and the two sides side slope, what the steel work dam body mainly bore is pressure, the technical requirements height of structural steel design need need comparatively complicated trussed construction according to the design of landform specific aim during construction, and need to increase truss thickness so that improve the pressure that it bears, thereby increased construction cost.
Summary of the invention
In order to overcome the deficiency that prior art exists, the invention provides a kind of cable wire dam.
Technical scheme: a kind of cable wire dam, comprise trussed construction dam body and steel work water retaining facing, the lower end of trussed construction dam body is fixed on the dam foundation concrete bearing platform, distributing on each support node of trussed construction dam body is fixed with cable wire, each cable wire along countercurrent direction be tilted to the upstream tractive and be fixed in the rock stratum or two sides concrete side slope on.
The one or both ends Y-shaped composition cable wire of cable wire, each minute cable wire be separately fixed on the adjoining support node, perhaps be fixed on the diverse location of side slope rock stratum.
The two ends of trussed construction dam body are fixed on the concrete side slope of two sides.
The vertical pillar lower end of trussed construction dam body is provided with joint angle, is embedded with set bolt in concrete bearing platform, and each joint angle is by being bolted on the concrete bearing platform, and the lower end of concrete bearing platform is provided with the stake of going deep in the riverbed simultaneously.
The trussed construction dam body is that a kind of convex globoidal is the arch of upstream face.
Beneficial effect of the present invention:
1. cable wire of the present invention dam has simple in structure, construction and maintenance easily, the advantage of short construction period, because cable wire has been alleviated the pressure that the two sides side slope is born to a great extent, so it is less demanding when building the dam to the two sides side slope, be applicable to multiple landform, even can save processing, also alleviated the tractive force of dam body simultaneously to a great extent the bottom cushion cap to dam abutment two sides side slope cushion cap.
2. utilize cable wire as the main load carrier of dam body, because that steel work bears tension strength easily is big, reduced the complexity of trussed construction, Stability Analysis of Structures is reliable, and long service life significantly reduces costs.Being suitable for suitability for industrialized production and assembled on site implements.
