The present application relates to rock mass supporting technical field, provide a kind of integrated anchor cable for soft disintegrating rock mass and construction method, integrated anchor cable includes anchor cable, grouting pipe, expansion capsule, anchor cable tensioning lock, tray and aligning ball pad, anchor cable includes anchor cable exposed section, anchor cable tensioning section and anchor cable anchoring section in turn;The import of grouting pipe is set at anchor cable exposed section, the outlet of grouting pipe is set at the junction position of anchor cable tensioning section and anchor cable anchoring section;Expansion capsule is wrapped in the local cable section of anchor cable tensioning section, local cable section corresponds to the orifice position of drilling, expansion capsule is connected with grouting pipe, and expansion capsule expands under the grouting pressure of grouting pipe.By waterproof anchoring agent, anchor cable anchoring section is fixed with the hole wall of drilling, and the orifice of drilling is sealed by expansion capsule, avoid the leakage of slurry along the orifice position of drilling, can realize good tensioning effect and grouting effect, can provide good supporting capacity for soft disintegrating rock mass.

This invention provides a tension leg floating foundation, a construction method, and a wind turbine generator set. The tension leg floating foundation includes: a floating body, comprising a main column and connecting bodies spaced apart around the main column. The main column is used to connect to the wind turbine body, and one end of each connecting body is connected to the second end of the main column. Multiple tension assemblies are spaced apart around the floating body. Each tension assembly includes tension legs and a mooring connection. One side of the tension leg is universally connected to a connecting body, and the other side protrudes from the connecting body towards the first end. The mooring connection is located on the side of the tension leg that protrudes axially from the connecting body. A mooring cable is provided for each tension leg. Each tension leg has a clearance cavity extending axially through it. One end of the mooring cable is inserted into the clearance cavity and connected to the mooring connection, while the other end is used for connection and fixation to the seabed. This invention can reduce the difficulty and cost of wind turbine foundation construction.
