Description
Technical field
The present invention relates to civil engineering suspension bridge construction fields, and in particular to realizes that a kind of main cable strand utilizes trailer system
Conversion equipment realizes that construction system and method in place are once drawn in the narrow space of Super Long Tunnel anchor.
Background technique
Main rope of suspension bridge strand is drawn when dissipating cable saddle to tunnel anchorage, due to slope change, narrow space, heavy mechanical equipment
Can not start tunneling, primary traction cannot achieve in place using conventional main cable strand traction technique, led at this time using this system
It crosses device and simply converts and can achieve primary traction in place, improve propulsive efficiency.
Summary of the invention
Therefore, in order to solve above-mentioned deficiency, the present invention provides a kind of main cable strand realization narrow space of Super Long Tunnel anchor herein
Primary construction system and the method drawn in place efficient, safety can once draw main push-towing rope in place.
It is once drawn in place the invention is realized in this way constructing a kind of main cable strand realization narrow space of Super Long Tunnel anchor
Construction system, it is characterised in that: the construction system has trailer system and conversion equipment；
Wherein, the composition of trailer system structure mainly includes dissipating cable saddle door frame, chain block, cat road door frame, cat road door frame guide wheel
Group, major-minor rack winch, hauling rope, pull device, cat road bottom plate is led, horizontal guide sheave, anchoring steel pipe；It will be led by pulling device
