2, shield structure tune
The shield structure turns to, the shift operation step:
1) manual monitoring is adopted in shield structure jacking, after several centimetres of every jackings, suspends jacking, and whether measure jacking synchronous, and the jacking process adopts interim cushion block to support;
2) after jacking is finished, place rolling bar or disc type bearing, take out interim lip block, the shield structure falls sinking to rolling bar or disc type bearing;
3) utilize the hoist engine traction that 90 ° of levels of shield structure Caudad Starting Well are turned to.
4) shield structure horizontal movement is passed the down-hole crossbeam and is arrived the uplink position of appearing.
5) shield structure head turns to (finishing the shield structure turns to for 180 °) to the 90 ° of levels in the side of appearing.
6) the shield structure is aimed at the orientation axis orientation.
7) shield structure jacking, remove rolling bar or.
8) to press axis in place for the shield structure, and operation is finished.
There is the deficiency of following several respects in the turn round method of above-mentioned existing shield machine in active well;
