Description
Technical field
The present invention relates to field of civil engineering, and in particular to a kind of main cable strand realized in Tunnel-Type Anchorage of Suspension Bridge quickly arrives
Up to the quick construction method in place in preceding anchor face.
Background technique
After anchorage is drawn using the main rope of suspension bridge strand of tunnel anchorage to tunnel anchorage, because there is space in tunnel anchorage
Limit, heavy mechanical equipment can not start tunneling, cause main cable strand cannot reach before anchor face.Elevator machine travel can only be used at this time
Anchor face before the method that steel cable pulls strand anchor head reaches it.Directly steel cable is bundled on strand anchor head and is possible to damage anchor head
Or rub with strand steel wire, therefore need to be improved.
Summary of the invention
Before so that main rope of suspension bridge strand is quickly reached tunnel anchorage the purpose of the present invention is to provide a kind of special fixture of utilization
The method in anchor face；Increase main push-towing rope propulsive efficiency, and main cable strand will not be had an impact.
Step 1: special fixture processing:
Special fixture is all made of 20mm thick steel plate, jig frame by jig frame, pulley blocks, upper lower clamp plate composition, material
And 25 bolt hole of φ is arranged in upper lower clamp plate, is connected using M24 plain bolt；
Step 2: special fixture is connect with strand anchor head:
Jig frame is covered in main cable strand anchor head position, lower clamp plate is installed, uses the fixed special fixture of bolt and rope
Stock anchor head；
Step 3: it is in place that hoist engine draws strand:
After special fixture and strand anchor head connect, it is connect around pulley cabling with hoist engine by steel cable, starts elevator
Machine travel strand reaches anchor face before tunnel anchorage.
It is of the present invention it is a kind of so that main rope of suspension bridge strand is quickly reached tunnel anchorage using special fixture before anchor face construction
Method；Main rope of suspension bridge propulsive efficiency is improved, and guarantees construction quality.
The present invention has the advantages that the present invention is connect using special fixture with strand anchor head by improving, then by dragging
The mode for dragging fixture can achieve same effect and will not influence strand.In addition pulley blocks are installed on special fixture can be improved
Efficiency is pulled, various tonnage hoist engines are suitable for, construction efficiency is high, and cost reduces.The present invention also has the following advantages that；
1, special clamp structure is simple, easy to use, and propulsive efficiency can be improved.
2, special fixture and strand anchor head are easy to connect.
3, special fixture will not damage influence to main cable strand anchor head in use.
4, special fixture can be recycled, and reduce costs.
Detailed description of the invention
Fig. 1 is special fixture and main cable strand anchor head connection schematic diagram；
Fig. 2 is upper and lower clamping plate schematic diagram；
Fig. 3 is the jig frame schematic diagram for assembling pulley.
Wherein: jig frame 1, pulley blocks 2, upper lower clamp plate 3.
Specific embodiment
Below in conjunction with attached drawing 1- Fig. 3, the present invention is described in detail, technical solution in the embodiment of the present invention into
Row clearly and completely describes, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
Every other embodiment, shall fall within the protection scope of the present invention.
The present invention a kind of makes in Tunnel-Type Anchorage of Suspension Bridge main cable strand quickly using special fixture by improving to provide herein
The construction method of position；Increase the speed of main rope of suspension bridge strand location and installation in tunnel anchorage, operation becomes simple, to protect
Demonstrate,prove construction quality and save the cost.
1-3 the present invention is further explained specific embodiment with reference to the accompanying drawing:
It is a kind of to make the quick construction method in place of main cable strand in Tunnel-Type Anchorage of Suspension Bridge using special fixture, make suspension bridge master
The speed of cable stock location and installation in tunnel anchorage increases, and operation becomes simple, to guarantee construction quality and save the cost.
Step 1: special fixture processing: special fixture is made of jig frame 1, pulley blocks 2, upper lower clamp plate 3, and material is equal
Using 20mm thick steel plate, 25 bolt hole of φ is arranged in jig frame and upper lower clamp plate, is connected using M24 plain bolt；
Step 2: special fixture is connect with strand anchor head: by 1 set of jig frame in main cable strand anchor head position, being installed
Lower clamp plate uses bolt stationary fixture and strand anchor head；
Step 3: hoist engine traction strand is in place: after special fixture is connected with strand anchor head, by steel cable around special
Fixture middle pulley cabling is connect with hoist engine, and starting hoist engine traction strand reaches anchor face before tunnel anchorage.
The present invention has the advantages that
1, special clamp structure is simple, easy to use, and propulsive efficiency can be improved.
2, special fixture and strand anchor head are easy to connect.
3, special fixture will not damage influence to main cable strand anchor head in use.
4, special fixture can be recycled, and reduce costs.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and the principles and novel features disclosed herein phase one
The widest scope of cause.
