The recessive benefit of anchor bolt

Anchor bolt is the most basic constituent part of tunnel support. It reinforces tunnel with surrounding rocks, realizing self-support. Now, anchor bolt can not only applied in tunnel, but also in engineering technology, having reinforcement for slope, mine, dam and infrastructure construction. Especially in fractured rock mass, the function of rock bolt is obvious. In […]

Underground Diaphragm Wall Features in Deep Foundation Pit Supporting Design

During excavation of deep foundation pit, underground diaphragm wall has functions of seepage-prevention, earth retaining and load bearing. Its specific features are as following: 1. Its stiffness is benefit for controlling deformation of foundation pit, especially for foundation pit engineering with narrow space and strict requirement in deformation. 2. It has strong impermeability and vertical […]
