Gabion mesh is used inrevetment cedar pilesscheme design

The slope ratio of the low-water revetment design scheme is 1:215, the elevation of the foot protection is 0.15m, and the elevation of the slope protection top is 415m. The slope protection adopts a 0.125m thick gabion net microbial slope protection structure, with a 0.120m thick sand, gravel and foundation cushion underneath. The specifications and model are 300g\/m1 reverse filtration anti-seepage geotextile; the foot protection is made of C20 concrete structure, 120m wide and 0.15m thick. The bottom of the foot protection is made of wooden columns with a length of 410m and a vertical interval of 120m; the outside of the foot protection is made of riprap. The width is 260m, the side slope ratio is 1:260, and the riprap surface is protected by a gabion net with a thickness of 0.145m. 212mm)

(1) Construction of riprap foundation engineering: Use a 5t dump truck to widen the vertical dumping forward with the end-entry method, carry out construction lofting according to the project construction sections, and throw according to the standards of horizontally from low to high and vertically from outside to inside. The weight of the thrown sand and gravel blocks is 30-50kg, and the sizes are matched when throwing. After the riprap body exceeds the predetermined cross-section and is stabilized by rolling, the riprap body is sorted and formed according to the designed outline.

(2) Construction of foot protection foundation: Place anti-corrosion treated pine wood piles with a pile length of 410m and a tail diameter of 0.114m every 120m according to the piling position laid out for construction, and use an excavator to drive them to the designed top elevation. When encountering riprap during the driving process, make appropriate adjustments to the piling position according to the proven range, depth 1, width, and piling position.
