Mutually the problem of conflict；The invention remarkable in economical benefits, high to space utilization rate in tunnel anchorage, anchor system safety is good.
The invention is realized in this way a kind of meet the main track cable layering of CABLEWAY ERECTION SYSTEM in narrow space tunnel anchorage
Arrangement system, it is characterised in that: anchor face anchors steel band according to the simulation layered arrangement of spatial position before tunnel anchorage and anchoring is slided
Vehicle, tunnel face turn cable saddle and are designed as bilayer, are conducive to dissipate cable saddle two sides and preceding anchor face arrangement sufficient amount in narrow tunnel anchorage
Main rope, and avoid the conflict area between each main rope.
One kind meeting the main track cable layered arrangement method of CABLEWAY ERECTION SYSTEM in narrow space tunnel anchorage, mainly arranges
Include:
Arrangement one: the arrangement of anchor face anchoring coaster before tunnel anchorage:
The arrangement for anchoring coaster can be designed as according to preceding anchor face using the size of area and the design requirement of anchoring coaster specification
Layering point column arrangement.Spacing herein needs to consider main rope anchoring connector and the influence that conflicts between adjacent main rope and its connector.
Arrangement two: tunnel anchorage hole bilayer steering cable saddle:
Since there are scattered cable saddle and scattered cable saddle door frame in tunnel anchorage hole, in order to avoid main track cable and scattered cable saddle and scattered cable saddle door frame rush
It is prominent, the double-deck steering cable saddle is usually arranged in scattered cable saddle two sides.The position and height for dissipating cable saddle should carry out Accurate Analysis, need to consider
To two linings thickness and ensure whether to exist between steering cable saddle and preceding anchor face anchoring coaster after main rope layered arrangement and hand over
Pitch conflict area.
Arrangement three: main track cable winding sequence arrangement:
It is more concatenated forms for main track cable, the main track cable of selective analysis is needed to turn in the double-deck steering cable saddle and preceding anchor face
Winding sequence between coaster.Ensure that after main rope is layered be not in rope anchoring connector and conflicting between adjacent main rope and its connector
The case where.
Meet cable crane in narrow space tunnel anchorage the present invention has the advantages that the purpose of the present invention is to provide one kind
The system and method for the main track cable layered arrangement of dress system is avoided that due in the individually designed anchoring temporarily system in tunnel anchorage hole
System, and increased great amount of work；It also can solve in narrow tunnel anchorage simultaneously, layered arrangement main rope, it is ensured that main rope
The problem of not conflicted with each other between main rope；The invention remarkable in economical benefits, anchoring high to space utilization rate in tunnel anchorage
Security of system is good.The present invention also has the following advantages that；
(1) it will be maximized in tunnel anchorage using space；
(2) it is necessary to ensure that under the premise of main rope radical and safety coefficient, effective solution nothing in narrow space tunnel anchorage
Method single layer be arranged side by side main rope the problem of；
(3) the characteristics of space is utilized by Accurate Analysis and rationally, can effectively avoid being likely to occur due to hierarchical design
Main rope anchors the problem of connector and conflict of adjacent main rope；
(4) by specific main rope cabling sequence, influence when effectively reducing main rope sag adjustment to anchoring temporarily main rope；
(5) anchor system utilizes the male cone body of permanent structure, does not need as conventional method, and independent pre- answer is arranged at hole
Power anchor system, greatly reduced project amount, also further ensure that the safety of anchor system.
