Hydraulic herringbone steel dam

Abstract

The invention relates to a hydraulic herringbone steel dam which is mainly applied to the construction field of water conservancy projects such as damping and impounding in rivers and reservoirs, farm irrigation, small hydroelectric stations and the like. The hydraulic herringbone steel dam is composed of a plurality of water damping panel units according to different water damping surface widths, all the water damping panels are firmly fixed into a dam foundation by bed shafts through hinge pedestals, the reverse sides of the water damping panels are connected with big hydraulic cylinders and supporting systems, and the water damping panels are driven to rotate by controlling the stretching of the hydraulic cylinders, therefore, dam erecting and laying are achieved; and when the water damping panels reach a designed supporting position, the supporting systems come into play, and form a stable triangular supporting structure with the water damping panels and the dam foundation. The hydraulic herringbone steel dam provided by the invention has a simple structure, is quick in dam erecting and laying, is safe and reliable, economic and durable, and is free of limitations from water quality and location.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, and more specifically relates to a hydraulic herringbone steel 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...

Problems solved by technology

With this structure, during the opening and closing process, the bottom shaft of the steel dam gate is hydraulically driven to drive the dam face plate to rotate. Since the water retaining face plate of the steel dam gate is an integral structure with a relatively large span, the bottom shaft is bulky and the power of the driving device is relatively large. , resulting in high investment; hydraulic drive has very high requirements on the levelness of the bottom shaft and is sensitive to foundation deformation, so it has very high requirements on foundation civil construction and cannot adapt to the settlement of dam foundation

Especially in long-span river courses, it is necessary to build a relay control pump room, which not only blocks water significantly, resulting in poor flood flow, but also makes it difficult to control the hydraulic synchronous lifting of large-span steel dam gates, and the bottom shaft is easy to bend and shift, resulting in Conditions of use are restricted
