Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] The steel structure dam with cable buttress is mainly composed of two parts: one is the cable buttress supporting the steel structure panel, its main function is to fix and restrain the steel structure, and transmit the huge water thrust formed by the steel structure to the The foundation is used to maintain the stability of the entire dam body. In addition, the pier structure can also be equipped with a drainage system to discharge excess water. The second is the steel structure panel mainly composed of beams, partitions, panels, etc., and its main function is to retain water. In addition, concrete pedestals are included, whose main function is to connect the steel structure to the foundation. The specific instructions are as follows:

[0025] Such as figure 1 As shown, the overall structure of the cable-supported steel dam of the present invention includes...

Abstract

The invention discloses a dragline buttress steel dam, which comprises buttresses, water-retaining steel structures and pedestals, wherein steel structure panels positioned among the buttresses form dam sections; the steel dam comprises a plurality of the dam sections; seams are formed among the dam sections; the buttresses comprise reinforced concrete buttress bodies, draglines and drain structures; the draglines are placed on the upstream surfaces of the buttresses and are anchored inside the buttresses through anchoring structures; the drain structures are placed on the buttresses on the dam sections of a middle river bed; the reinforced concrete pedestals are arranged on a base; and bottom holes are formed in the pedestals. The dragline buttress steel dam has the characteristics of flexible project layout, simple structure, stability and reliability, and can adapt to a higher water-retaining head (70 m) and larger discharge. Compared with the scheme of a traditional concrete gravity dam, the dragline buttress steel dam can save more than 15 percent of engineering investment within the dam height of 70 m under the same external conditions and functional requirements.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a steel structure dam. Background technique [0002] As a kind of water-retaining structure, steel dam has a history of more than 100 years. In the earliest steel dams, the panels and components were connected by welding or bolts, which made full use of the characteristics of high strength and flexibility of steel, so that the dam body has very good integrity and flexibility, and can better adapt to the deformation of the water body The requirement is an advanced new technology for dam engineering. The United States once built the Ashfork steel dam on October 7, 1897. The total length of the dam is 91.4m. The steel structure dam is 14m high and 56m long. Both ends of the steel structure dam are equipped with masonry gravity dams. It is the earliest steel structure dam in the world. one. From 1900 to 1960, several steel dams were successively built in Aust...
