Segmented-winged butterfly-shaped slope protection net system and design method thereof

Abstract

The present application discloses a segmented wing butterfly-shaped slope protection net system and its design method. In view of the defects of the existing continuous passive protection technical scheme of the slope, the present application provides a segmented wing butterfly-shaped slope protection net system. The system comprises at least two protection segments along the slope, the protection segment support column is perpendicular to the slope and arranged in a single slope continuous span along the slope, the protection net face is wide in front and narrow at the back, high in front and low at the back, the upper segment outlet is narrower than the lower segment inlet, and the upper segment outlet is lower than the lower segment inlet. The present application introduces the idea of bionics, the longitudinal structure simulates the trunk segment of crustacean, and the transverse structure simulates the butterfly shape, forming a continuous protection net structure with the characteristics of "fitting and waist tightening", and realizing the overall protection concept of "active energy consumption + dredging". The present application provides a design method of the protection net system and a design method of the energy consumption ring steel strand number of the winding type ring net. The technical scheme of the present application can completely adapt to the mountainous slope prevention engineering technology and cost limitation, and is suitable for popularization and application in mountainous areas.
