Technical field
The present invention relates to field of civil engineering, and in particular to one kind realizes that main rope of suspension bridge strand second traction enters tunnel
The construction method of anchor.
Background technology
At present, more Analysis of Suspension Bridges ' Anchorage system is designed to tunnel-type anchorage, and its feature of the anchorage of this form is space
It is long and narrow and with certain inclination angle.Because sectional space is narrow and small in tunnel anchorage, dissipated in tunnel at cable saddle buttress, dissipate cable saddle and door
Frame system can occupy suitable large space.It will result in main push-towing rope and draw to tunnel anchorage and dissipate at cable saddle buttress, what traction was used pulls device
Occur position with portal frame system to conflict, prevent the traction of main cable strand.
The content of the invention
It is an object of the invention to provide a kind of main rope of suspension bridge strand second traction herein to enter the side that tunnel anchorage is constructed
Method, using second traction method, replaces traction using device is pulled, and main cable strand was smoothly drawn and cable saddle door is dissipated in tunnel anchorage
Frame, effectively and safely perform.So as to ensure construction safety, improve effect, cost-effective.
The present invention is achieved in that a kind of main rope of suspension bridge strand second traction enters the method that tunnel anchorage is constructed, profit
Solve to pull the problem of device conflicts with scattered cable saddle door frame with the device of simple and convenient, it is characterised in that：Comprise the following steps：
Step one：Releasing pulls device and is connected with strand：Strand anchor head is connected with pulling device releasing, steel cable is temporarily utilized by strand
Anchor head is fixed near tunnel anchorage hole；
Step 2：Hauling rope is fallen back：Using single line reciprocating-type tractor system is by hauling rope and pulls device retroversion 100m（To lead again
It device is pulled after drawing will not advance to scattered saddle's position and be advisable）；
Step 3：Tunnel anchorage pulls device and is connected with strand：The special device that pulls of tunnel anchorage is fixed with hauling rope, and main cable strand
Anchor head is connected with the special device that pulls of tunnel anchorage；
Step 4：Frame strand is handled：Strand is drawn after tunnel anchorage, it will passed through directly over from scattered cable saddle, and strand will be dragged
It is drawn into cable saddle saddle groove, is rubbed with frame strand, therefore set roller lattice to keep off in saddle groove, it is to avoid strand rubs in traction
Wipe；
Step 5：Traction is in place：Start trailer system hoist engine, strand drawn to preceding anchor face, complete main cable strand draw into
Tunnel anchorage works.
The invention has the advantages that：Enter tunnel anchorage the invention provides a kind of main rope of suspension bridge strand second traction
Construction method；Comprise the following steps：（1）Releasing pulls device and is connected with strand；（2）Pull rope is fallen back；（3）Tunnel anchorage pull device with
Strand is connected；（4）Frame strand is handled；（5）Traction is in place.In Tunnel-Type Anchorage of Suspension Bridge, the narrower tunnel anchorage in space, main push-towing rope
In the case that traction is using typically device is pulled, usually can not once it be drawn with the generation position conflict of cable saddle door frame is dissipated in tunnel anchorage
In place.Fast and effectively by second traction main cable strand can be made smoothly in place to preceding anchor face by the present invention, main push-towing rope can be increased
Propulsive efficiency, it is cost-effective.
The present invention also has the following advantages that：
1st, the tunnel anchorage complicated without design dissipates cable saddle door frame.
2nd, conventional main rope of suspension bridge trailer system can be just applicable.
3rd, temporary structure facility at cable saddle is dissipated in tunnel anchorage can not influence follow-up strand to enter saddle according to conventional arrangement completely
Construction.
4th, efficiency high, time and labour saving, and safety.
