3. add the monitoring of the power of wringing and distortion in stretching process, make every effort to the accuracy measured, when monitor data error is larger, should stretch-draw be suspended, analytical error reason.
5) stretch-draw surveying record: first record drag-line original length, every stretch-draw one-level, then record pressure sensor and record pressure and total powerstation records agent structure deformation values, after stretch-draw completes, surveying record drag-line drift again, record overall stretch value, to carry out overall process monitoring to stayed structure and agent structure.
6) pulling force monitoring, check: because metal material self-characteristic can produce a certain amount of creeping in length after cable tension, value of thrust also can decline thereupon, therefore drag-line pulling force need carry out detection check after 5 days, if survey numerical value exceed scope of design should give in time stretch-draw adjustment, what value of thrust was less than design load carries out tensioning, the carrying out exceeding design load unloads power, such that the value of thrust with a pair drag-line is impartial and difference is no more than 5kN.
5.5 points for attention
1) structure stress situation and the Suo Li situation of change of each stretch-draw step should be calculated in detail, ensure that structural element and Cable forces are no more than limit condition design value, have enough safety stocks.
2) for ensureing the safety of structure and tensioning tooling, tension operation strictly should control stretching force, and stretching force must not exceed theoretical value 10%, and drag-line stretch value is listed in target Suo Libiao.
3) cable tension completes, and carries out Suo Li actual measurement, and adjustment mechanical model, checks the safety of stayed structure under various load case, guarantee safety of structure.
Finally, stretching construction monitored and check and accept
