Problems solved by technology

Steel dams have a history of more than 120 years, and their types mainly include inclined-plane steel dams, arched steel dams, and flexible reverse-arched steel dams. Many, especially the flexible steel dam as a light structure, there are technical problems in the construction process, such as the auxiliary fixing of the steel plate during welding, the effective connection between the dam body and the concrete base, and the concrete abutment, etc. Both need to be studied and solved. Based on this, we propose a construction method for flexible steel dams

Abstract

The invention proposes a flexible steel dam construction method, which belongs to the technical field of hydraulic engineering. The flexible steel dam includes a dam body, a concrete base, a concrete dam abutment, and channel steel. The bottom is connected in the slot of the channel steel; the dam body includes several dam body layers that are stacked and connected to each other from bottom to top, and each dam body layer includes a plurality of mutually welded steel plate units; The concrete abutments are connected, and the bottom of the concrete abutment is connected with the concrete base to form the flexible steel dam. The invention has the characteristics of high strength and good flexibility, and the dam body has good tensile properties; at the same time, it has the advantages of environmental protection and economy, short construction period and convenient dismantling and construction.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a flexible steel dam construction method. Background technique [0002] A dam is a water-retaining structure that intercepts the river flow and stores water in front of the dam to form a reservoir area. Usually, earth dams, rockfill dams, masonry dams, concrete dams, etc. are used. Steel dams have a history of more than 120 years, and their types mainly include inclined steel dams, arch steel dams and flexible reverse arch steel dams. In particular, the flexible steel dam is a light structure, and there are technical problems in the construction process, such as the auxiliary fixation of the steel plate during welding, the effective connection between the dam body and the concrete base and the concrete abutment, etc. All need to be studied and solved. Based on this, we propose a construction method for flexible steel dams. SUMMARY OF THE INVENTION [0003] In o...
