Riverbed diversion structure for hydraulic engineering construction

Abstract

The invention discloses a riverbed diversion structure for hydraulic engineering construction, and and relates to the technical field of hydraulic engineering equipment. The riverbed diversion structure comprises a flow guiding screen device, the flow guiding screen device is provided with a front screen wall structure and a rear screen wall structure, the back face of the front screen wall structure of the flow guiding screen device is provided with an air sand removing and impurity discharging device, an adjusting sand conveying device is arranged between the bottom of the front screen wall structure and the bottom of the rear screen wall structure of the flow guiding screen device, the flow guiding screen device comprises a screen wall, a sand filling groove is formed inside the screen wall, the adjusting sand conveying device comprises side frame rods, the tail end of at least one of the two side frame rods is provided with an adjusting screw hole structure, and an inclined frame rod is arranged between the two side frame rods. When the riverbed diversion structure for the hydraulic engineering construction is used, a cofferdam does not need to be arranged in advance, the riverbed diversion structure has the characteristics of being convenient to arrange, high in reuse rate, flexible and adjustable, water quality pollution cannot be caused when the riverbed diversion structure is assembled or disassembled, and the problems that many existing flow guiding screen devices are tedious in arrangement, low in reuse rate, unadjustable and large in pollution after being disassembled can be solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering equipment, in particular to a river bed diversion structure for hydraulic engineering construction. Background technique [0002] Construction diversion refers to the construction of water conservancy and hydropower projects, in order to keep hydraulic structures on dry ground, use cofferdams to maintain foundation pits, and direct water flow to predetermined drainage structures to discharge downstream measure. Construction diversion is a very important engineering measure unique to hydraulic engineering construction, especially the construction of sluice dams. It is divided into full-section cofferdam method and segmented cofferdam method. [0003] An engineering facility that controls and guides the direction of water flow to form an artificial circulation to prevent sediment deposition, also known as a diversion screen. The diversion device can be divided into two types: fixed t...
