Internal fixation body wedge assembly and using the same for tensile material removal shape internal fixation of the ground anchor

摘要

Topic When external fixation of the tension member is cancelled when the fixation load has put on the tension member which it becomes fixed to the subterranean anchor borehole also the wedge putting is cancelled, removal preparation of the wedge assembly and the pulling vessel etc which can remove the tension member being dying very easy, the wedge assembly for the fixation body inside tension member removal shape for the ground anchor - which can remove the tension member efficiently and inside this is used offers the fixation body.SolutionsIt forms the helical putting blade in the inside of the wedge, puts the elastic ring to the external point and tries to be able to keep the assembly state of the cyclotomy condition wedge, the internal first portion of the aforementioned wedge puts the sliding surface which does not have the blade it makes, in the point in circumferential direction the traction nail forms the wedge traction board uses, in rear rank of the aforementioned traction nail the internal piston-ring groove for the wedge open ring forms. It is desirable, the aforementioned wedge when backing up to circumferential direction on the back of the external piston-ring groove, is put by the wedge lock ring, furthermore possesses the lock groove which is locked.
