Environmentally-friendly slope-attaching type trash rack and building method thereof

Abstract

The invention relates to an environmentally-friendly slope-attaching type trash rack and a building method thereof and belongs to a structural style of trash rack arrangement. The trash rack comprises a hoist chamber. The contact portions of trash rack piers and a mountain are of step shapes. An included angle alpha between the trash rack piers and the horizontal plane is from 60 degrees to 80 degrees. A connecting beam is connected between the two trash rack piers. Each trash rack pier is provided with a trash rack gate groove. The connecting beam is connected with the mountain in a contacting mode. The trash rack piers or the connecting beam and the mountain are fixedly connected through anchoring rods. Trash rack gates are connected with the trash rack gate grooves in a sliding mode. The trash rack has the advantages of being simple in structure, reliable in operation, and suitable for the geography with the natural side slope grade of 60 degrees to 80 degrees, natural slope covering layers and the geological condition of shallow rock mass weathering. The trash rack achieves the purpose of trash holding, attention is paid to the combination of the trash rack and the natural mountain slope, the requirement of the structural functionality is met, the purpose of ecological environmental protection is achieved, and the trash rack has the good application prospect.

Description

technical field [0001] The invention relates to a structure type of trash rack arrangement, in particular to a trash rack arrangement type against a slope, which is suitable for independently arranged water inlets and trash racks arranged along slopes on terrain with a slope greater than 60°. Background technique [0002] The function of the trash rack is to prevent dirt from entering the water inlet, thereby affecting the normal operation of the turbine. The layout of the trash rack depends on the type of water inlet and the size of the power station’s reference flow, the local climate conditions, the range of water level changes in the reservoir, the minimum size of the trash held by the trash rack, and the cleaning method. It can be arranged as a straight line and a semicircle (usually a polygon) on the plane, and it can be vertical or inclined on the facade. The trash rack can also be fixed or movable according to maintenance requirements. [0003] In the past, the wat...
