Inverted arch steel structure dam with resistance piers

Abstract

The invention discloses an inverted arch steel structure dam with resistance piers. The inverted arch steel structure dam comprises a concrete foundation, a plurality of resistance piers, a water blocking steel structure and a hydrocone type water-drainage energy-dissipation building, wherein the water blocking steel structure is fixed on the concrete foundation, the plurality of resistance piers are arranged on the downstream of the water blocking steel structure which is composed of a middle inverted arch dam section and two arch dam sections, the two arch dam sections are fixed on two sides of the middle inverted arch dam section symmetrically, and the hydrocone type water-drainage energy-dissipation building penetrates through the top of the middle inverted arch dam section and the corresponding resistance piers. By utilizing the scattered resistance piers arranged at the downstream, water heads borne by the water blocking steel structures of the two arches on two sides of the middle inverted arch are diffused on the concrete foundation, the steel structure dam can adapt to high water heads and large flow, the construction efficiency is increased, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of water conservancy and hydropower engineering, in particular to a steel structure dam body used for blocking and discharging water in a river course. Background technique [0002] In water conservancy projects, steel dams have been used as a water retaining structure for more than a hundred years. Steel dam is a new type of water-retaining structure. It has novel structure, beautiful appearance, reliable performance and flexible use. It better solves the contradiction between water storage and flood discharge in the river, and is beneficial to protect the natural environment of the river. However, the steel dams built in the early days were all inclined dams, and the truss support system was adopted behind the dam surface. In water conservancy projects, steel gate water-retaining structures similar to steel dams have been used for many years. In recent years, new gates have emerged one after another. The ...

Problems solved by technology

However, the current research and practice on steel dams are still in their infancy. The existing steel dams are mainly of small and medium water heads, and their operation and management are complicated. Their structural construction and management are similar to steel gates.

Since most of the initial steel dams adopt the inclined steel dam type, the amount of steel used is large, the investment is relatively large, and some related technologies such as calculation technology, anchoring technology, anti-rust technology are outdated, etc. In addition, the steel output is small and the construction technology is relatively backward. In order to avoid wasting steel, steel dams are not built at all. In addition, there are no design specifications and procedures to follow for steel dam technology, and the design ideas are relatively conservative. Therefore, its industrialized manufacturing and installation are only in the exploratory stage, and there is no real steel dam. The innovation and development of the structure cannot meet the requirements of higher water head and larger discharge volume
