Construction techniques and technology of pre-stressed anchorage cable for the support of side-slope
Tong Guang-hai · Water power · 2003
In order to ensure the stability of side-slope during construction and operation periods, the pre-stressed anchorage cable has been used to reinforce the side slope in the construction of the left-bank side slope treatment in the Longtan Hydropower Project. It involves in boring hole, manufacturing and installing anchorage cable, grouting the inner anchoring section and pulling section, and pouring and pulling the cushion pad and outer anchorage head. According to the geological conditions of Longtan Hydropower Project, we treated the hole-paths in the clay inter-layers, micro-seepage and wet stratum, fissure layers, foundation rocks and other special layers. The consolidation grouting for the hole-paths has been adopted.
