large-diameter rock bolt
With increasing of excavation depth and complexity of surrounding environment, to meet demands of construction, length and diameter of also need to be increased.
Sheet-pile anchorage adopted in foundation pit mainly focuses on 4 aspects:
1. At stressing aspect, it mainly utilizes high-strength, strong-stiffness and big-shearing advantages of pile and .
2. Large-diameter self drilling anchor bolt has good supporting effect. It can also save materials, be simple and fast to construct and be benefit for mechanized operation.
3. Large-diameter self drilling anchor bolt can effectively solve problem of difficult to form holes in weak stratum.
4. It provides bigger space for inner construction of foundation pit, avoiding security risk and ensuring stability during construction.
Under the premise of saving construction costs, large-diameter self drilling anchor bolt in metro open cut pit reduces construction risk and ensures project’s duration.
