Description
Technical field
The present invention relates to bridge construction method field, a kind of self-anchored suspension bridge and its cat road separate type construction party are provided
Method.
Background technology
Cat road is located under main push-towing rope, is arranged along main push-towing rope, as a series of the logical of construction operations such as suspension bridge Cable system
Road and interim load-carrying members are large size and essential temporary project needed for suspension bridge construction.Cat road is usually by being suspended in
Several parallel carrier cables, crossbeam composition between tower and tower, tower and anchorage, are laid with wire rope net surface layer, nonslip tread, column thereon
Bar angle steel column, steel wire rope manrope etc. prevent it from waving and rising and falling to improve the wind resistance in cat road, generally need to also be in cat
Road lower part is arranged wind resistance rope or takes other only shake measures.
Cat road is as a kind of convenient, repeatable plate tunnel utilized, to main rope of suspension bridge cable erection, installing Cable-clamp etc.
It brings great convenience.It is the height scaffolding that construction personnel carries out construction operation, is that Cable system or even suspension bridge are entire
The operation platform of superstructure.Construction personnel completes such as strand traction, stock, shaping is adjusted to enter saddle, tight cable, cord clip and hang on it
Rope installation, main push-towing rope twine the vital tasks such as silk, protective coating.
Cat road track cable generally uses aerotow method erection construction, then installs cat road crossbeam, Mao Dao respectively in high-altitude
Face layer steel wire, nonslip tread, railing, manrope etc., due to all using working at height, conventional construction method working face
Narrow, operating difficulties, construction period is longer, and security risk is larger.
The use in cat road is constructed always through entire suspension bridge superstructure work, and service life is long, how to accomplish to apply
Work is easy, safe and reliable, expense is saved, and is the critical issue of cat road system design and construction.
Invention content
To make up the deficiencies in the prior art, the present invention provides a kind of self-anchored suspension bridge and its cat road separate type construction parties
Method, improves the erection efficiency of self-anchored suspension bridge construction catwalk, and fast and convenient, safe operation shortens the construction period, saves manpower, object
