章节摘录

插图：8 During grouting，if grout leakage occurs in inner anchoragesection due to breaking of grout stop ring，the tendon shall be pulledout SO as to flush away the grout in hole with clear water,replace thegrout stop ring，re-install the tendon and conduct grouting in the inneranchorage section.6.0.6 Relevant regulations for tensioning and locking of tendon：1 Test in-situ shall be conducted for tensioning of anchor barsSO as to determine reasonable tensioning techniques，to verify thetensioning parameters and tO avoid compulsory tensioning.2 Before tensioning，tensioning equipment shall be calibrated.3 Tendon tensioning shall be conducted according to specifiedprocedures.Tensioning procedure shall be designed by consideringthe mutual influence of adjacent tendons during tensioning.4  Before the formal tensioning，pre-tensioning shall beconducted once or twice with single-tendon jack to keep each part intight contact and steel wire or steel strand straight.The pre-tensioningload may be 20％——30％of the designed tensioning load.5 During the formal tensioning，tensioning and pressure。stabilizing shall be made according to the designed load increasing rangeand the stabilizing duration，and then locking shall be conducted.If theload increasing range and the duration of pressure stabilizing are notspecified in design，the tensioning load shall be increased tO 1 1 0％ofthe design one，and then the stabilizing pressure shall be kept at least2min before locking.6 Within 48 h afterlocking，ifloss ofprestress is larger than 10％of the design load，compensation tensioning shall be made.
