Soil nailing systems are advantageous in many circumstances
Soil nailing is a technique used to reinforce and strengthen existing ground. Soil nailing consists of installing closely spaced bars into a slope or excavation as construction proceeds from top down. It is an effective and economical method of constructing retaining wall for excavation support, support of hill cuts, bridge abutments and high ways. This process is effective in cohesive soil, broken rock, shale or fixed face conditions.
Soil nailing systems are advantageous in many circumstances. First, where construction schedules are critical, the general excavation can begin immediately in conjunction with a Sinorock, thereby reducing the overall project schedule. Second, soil nailing systems can be installed within soils that are too dense to be penetrated with conventional driven earth support systems. Finally, Sinorock are beneficial at sites where rock is at or above subgrade elevation , where additional “toe” would otherwise be required for conventional earth support systems.
