It falls；Slow down hauling speed at this time, being slowly adjusted to for main pole is realized by 3 points at main pole root, top, motor-driven grinding mill
Position, makes four bracing wires all around be connected on bracing wire anchoring pile and be strained and fixed, as external cable；Floor installation is held at this time
Support rope, a plurality of bearing rope connect main pole by multiple barbs respectively, and different height of the other end through corresponding pole hangs cunning
Vehicle group, wherein the hanging pulley group of secondary pole top is connect with main holding pole base with two groups of bearing ropes；Finally using main pole as branch
Point, stand up all secondary poles；By taking A points as an example, the tackle pulley in the middle part of main pole is displaced downwardly to the position at total high 3/8, is prolonged backward
Bracing wire to the motor-driven grinding mill for stretching middle part tackle pulley is fixed, at the top of the secondary pole of other end connection A points, setting drawing at the top of A point time poles
Line connects earth anchor backward；Motor-driven grinding mill, middle part tackle pulley, 3 points of secondary pole top are in same x-axis, using middle part tackle pulley as not
Dynamic point recycles middle part tackle pulley bracing wire by motor-driven grinding mill and stands up time pole；After the completion of a piece secondary pole stands up, tightening middle part is sliding
Vehicle group bracing wire is replaced sheet-type support using jack immediately and is fixed by the way of flanged joint, and bolt tightly after all bolts, is torn open
Except middle part tackle pulley bracing wire；Then the position of motor-driven grinding mill is adjusted, stand up remaining twice poles in the same way；Wherein institute
There is standing up for pole that should have special messenger, monitor the verticality of its front and side, if there is the abnormal traction of stopping immediately adjusting；It treats
After the completion of its three time poles all replace sheet-type supports, pole stands up formal completion, arranges and tightens bearing rope and main pole
External cable.
