由我院和铁道科学研究院、北京市水利工程基础处理总队合作,五局和碧口水电厂等配合,于1986年7月在碧口水电站引水隧洞进口边坡处理中试验成功单孔吨位450吨岩石锚索。 该岩石锚索孔深32米,钻孔直径150毫米,采用30根7φ5钢绞线分组张拉、槽销锚分组锚锭新工艺。该岩锚为目前国内水利水电工程中单孔吨位最大的岩石锚索,该岩锚的试验成功,表明所采用的一整套工艺和设备是可靠的,可供工程采用,并为进行更高吨位的岩锚研制铺平了道路。
By our institute and the Academy of Railway Science and Technology, Beijing Water Conservancy Engineering Foundation Corps, five bureaus and hydropower plants and other cooperation, in July 1986 in the Bikou Hydropower Station diversion tunnel entrance slope treatment successfully tested single hole tonnage of 450 tons Rock anchor. The rock bolt holes 32 meters deep, bore diameter of 150 mm, the use of 30 7φ5 Strand grouping tension, slot pin anchor grouting new technology. The rock anchor is currently the largest single-hole tonnage rock anchor in domestic water conservancy and hydropower projects. The successful test of the rock anchor shows that the whole set of technology and equipment used is reliable and can be used for engineering purposes. For the purpose of carrying out higher tonnage The rock anchor developed to pave the way.
