some high-class highway Facing wall construction programme

The face protection wall is used for the protection of strongly weathered rock slope, and the slope ratio is generally 1:0.5. The slope ratio of 1:0.75 can be used for local slopes whose slope is slower than 1:0.5 due to slope collapse after excavation. The face wall is divided into one section every ten meters, and an expansion joint is set in the middle (the joint width is 2cm, filled with asphalt waterproof material). The facing wall is poured with C15 rubble concrete
