A self-controlled steel face dam

Abstract

Disclosed is an automatic control type steel faceplate dam. The automatic control type steel faceplate dam is characterized in that a rectangular concrete water tank crossing a riverway serves as a foundation portion and is provided with a floating ball chamber, supporting seats are arranged on two sides of the top of the water tank, the water tank is provided with a water inlet hole and a water outlet hole which are communicated with the floating ball chamber, a water inlet and a water outlet are formed in the outer sidewall of the floating ball chamber, and slip-resistant ridges are arranged in the floating ball chamber; a foldable three-joint steel faceplate dam body formed by three rectangular steel plates through two steel hinges serves as a retaining dam portion, and two sides of the steel faceplate dam body are fixed on the two supporting seats at the top of the water tank respectively; a floating ball portion comprises a floating ball, a floating ball rod and watertight rubber, the perpendicular floating ball rod passes through a central hole of the slip-resistant ridges in the floating ball chamber, the floating ball and the watertight rubber are fixed at the upper and lower ends of the floating ball rod respectively, and a water supply and drainage portion comprises a water inlet pipe, a water inlet valve, a water pump, a water outlet pipe and a water outlet valve. The automatic control type steel faceplate dam has the advantages of simple structure and low construction difficulty, and short construction cycle, low cost and good economic applicability in engineering by adopting main components which can be pre-fabricated.

Description

technical field [0001] The invention relates to a water retaining structure in the field of hydraulic engineering, in particular to a self-controlling steel face dam. Background technique [0002] According to statistics, there are more than 50,000 rivers with a drainage area of ​​100-1,000 square kilometers in the country, a large part of which are located in mountainous areas. Rivers in mountainous areas have the characteristics of uneven distribution of water volume in time and space, and the flow rate in winter and summer varies greatly, which can reach hundreds of times. At present, gates are often used in water retaining and discharging facilities in water conservancy projects, which can be installed on hydraulic structures such as overflow dam sections, bank spillways, scuppers, hydraulic tunnels, etc., to intercept water flow, control water level, adjust flow, For the purpose of discharging sediment and floating objects. The traditional gate is a systematic project...

AI Technical Summary

Problems solved by technology

Generally speaking, the gate has the disadvantages of complex design, difficult construction and high cost.

Moreover, when the gate pier discharges water during the flood period, it will produce greater flood resistance, which will affect the water flow conditions in the river channel.
