Cable-pulled miter dam

Abstract

The invention relates to a cable traction reversed-V-shaped water retaining dam. The cable traction reversed-V-shaped water retaining dam is mainly applied to the hydraulic engineering construction field of water retention and storage of watercourses and reservoirs, farm irrigation, small hydropower stations and the like. A water retaining panel (1) of the water retaining dam is firmly connected to a dam foundation by a bottom shaft (8) through a hinge pedestal (9); a row of transmission supporting rods (2) are arranged on the back side of the water retaining panel (1) at equal intervals, connected into a whole through steel plate profiles and locked through a clamping device (11) to form a stable triangle supporting structure. A power device of the cable traction reversed-V-shaped water retaining dam is composed of a cable (7), a pulley block, the transmission supporting rods (2), a winch and the like; the pulley block is connected to the transmission supporting rods (2) and the dam foundation and are rotated positively and negatively through the winch, and therefore the dam erection and dam dropping are achieved. The cable traction reversed-V-shaped water retaining dam is simple in structure, fast in damp dropping and dam erection, safe, reliable, economical, durable and not limited by water quality or territory.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, and more specifically relates to a cable-drawn gable dam. Background technique [0002] With the development of human beings, water resources are becoming more and more tense. In order to make full use of water resources, dams are usually built in river courses, not only to achieve the purpose of water retention and storage, but also not to affect flood control safety, so dams are widely used. The dams currently used in engineering construction include automatic flap dams, rubber dams, and steel dams. [0003] The automatic flap dam has a row of pillar piers in the river channel, and water blocking panels are arranged between the pillar piers. It has the advantages of low cost, convenient operation and management, etc., but there are many problems in the automatic flap dam, mainly including: first, water blocking , cannot withstand the impact of severe floods; second, it is easy to b...

AI Technical Summary

Problems solved by technology

This dam erects and collapses quickly, and basically does not block water, but its structural force is unscientific, resulting in a bulky bottom shaft, and the cost is very high. If the span of the steel dam is large, the bottom shaft is easy to bend and shift, resulting in The conditions are limited, so it is not widely used in actual engineering
