Soft ground surface drainage method design, construction Note: ① groove arrangement groove layout should consider the use of the natural slope of the terrain drainage; backfill settlement to pay attention to changes in slope; not to surface water from around the excavation site, the penetration of water immersion filling; trench interval to be encrypted as possible, to increase the drainage capacity of Reinforcing anchor rig, even if some of the grooves are cut will not hinder the overall drainage. ② construction trench groove dimensions and generally wide 0.5m, depth 0.5 ~ 1.0m. Before filling in the trench backfill become blind ditch with a good permeable sand (gravel). Blind ditch along the road longitudinal general longitudinal or central longitudinal excavation, lateral blind ditch general arrangement pitch 10m ~ 15m. When embedded within porous drainage trench must be protected with high-quality filter layer.
