Description
Technical field
The present invention relates to the suspension cable field of bridge, be specially a kind of direct volume rope hanging cable method of main rope of suspension bridge strand.
Background technology
The erection construction of current main rope of suspension bridge mainly contains two kinds of methods: aerial braided cable method (AS) and prefabricated strand method (PPWS).During the operation of AS method, a rotating disk and trailer system is utilized to be suspended on bridge by individual wire, rotating disk shuttles in bridge two ends erection steel wire, the steel wire quantity included due to main cable unit cable strand is very many, can hundreds of be reached, such rotating disk needs back and forth to run the establishment that hundreds of times could meet a main cable unit cable strand, and the erection of a main push-towing rope needs tens up to a hundred main cable unit cable strand compositions, that is rotating disk is needed tens thousand of times back and forth with the main push-towing rope that AS method works out a suspension bridge, often need 1 year even time of several years, the time of at substantial and manpower, during AS method operation simultaneously, work difficulty is large, affect greatly by weather etc., the strand precision of establishment is low, each steel wire unbalance stress in rope, indivedual steel wire stress is caused to concentrate, be unfavorable for that the strand efficient high life is run, cause huge waste.During the operation of PPWS method, in factory, steel wire is made into strand in advance, then transporting cable strand is carried out hanging cable installation to bridge construction scene.It is high that PPWS method strand makes precision, and installation period is short, easy for installation, less by weather effect.But PPWS method need consider the transport of strand, need to make a large amount of logistics transportation equipment; Because strand tonnage is all larger, consider transportation problem, the specification of strand can only be reduced to tens to 100 multifibres; Strand specification reduces to make to have to during bridge construction set up anchorage at bridge two ends, causes anchorage seat bulky, adds the consumption of goods and materials; Due to the most of bad environments in bridge construction building site, particularly mountain road transport, the transporting cable strand of hundreds of ton is very difficult.
Summary of the invention
In order to overcome the defect of prior art, the suspension bridge suspension cable erection method that a kind of strand precision is high, long service life, short construction period, the consumption of materials are few, transport difficulty is low is provided, the invention discloses a kind of direct volume rope hanging cable method of main rope of suspension bridge strand.
The present invention reaches goal of the invention by following technical solution:
Rope hanging cable method is directly compiled at a kind of scene of main rope of suspension bridge strand, comprise planning unit strand, during planning unit strand, steel wire is released from thread discharge disk, wire sub-panel is entered through guide frame, after wire sub-panel sub-wire, send into closing device close up, take turns after shaping by traction unit machine travel unit through shaping again, transition apparatus is delivered to after winding machine is wrapped, complete planning unit strand, it is characterized in that: also comprise and establishment equipment is set, traction unit strand, hot casting anchor, cooling ground tackle, strand ground tackle and these 6 steps of Serial regulation are installed, planning unit strand complete establishment equipment is set after and carry out before traction unit strand.When establishment equipment is set, establishment district is set in one end of main push-towing rope hanging cable job site Construction of Pylon of Long Span Suspension Bridge, in establishment district, establishment equipment is set, establishment equipment comprises the thread discharge disk, excessively guide frame, wire sub-panel, closing device, shaping wheel, traction unit machine, winding machine and the transition apparatus that are arranged in order, transition apparatus is made up of fixed pulley, movable pulley and pillar, fixed pulley is fixed on pillar, movable pulley to be enclosed within pillar and to slide up and down along pillar, fixed pulley and movable pulley are staggered, and unit cable strand is embedded in the race of fixed pulley and movable pulley successively.During traction unit strand, by unit cable strand by hoist engine traction to the top of Construction of Pylon of Long Span Suspension Bridge, unit cable strand is drawn through tower top crawler belt and apparatus for shaping successively, after in across traction to another Construction of Pylon of Long Span Suspension Bridge.During hot casting anchor, the Construction of Pylon of Long Span Suspension Bridge at two ends arranges hot casting anchor platform respectively, and casting chill casting material, carries out hot casting anchor to strand.During cooling ground tackle, chill casting material is solidified the unit cable strand two ends cooling completing hot casting anchor.When strand ground tackle is installed, the strand ground tackle at unit cable strand two ends is separately fixed at the anchorage place at suspension bridge two ends.During LFM signal, according to linear with adjustment unit strand of the position of the design parameters adjustment unit strand of suspension bridge, the design parameters of institute's foundation comprises the sag, elevation, design temperature etc. of suspension bridge design.
Rope hanging cable method is directly compiled at the scene of described main rope of suspension bridge strand, it is characterized in that: after establishment equipment is set, planning unit strand and traction unit strand carry out simultaneously, namely namely the front end of steel wire starts traction unit strand after completing planning unit strand, the rear end of steel wire proceeds planning unit strand, and during planning unit strand when the traction unit speed of steel wire and traction unit strand the traction unit speed of unit cable strand be consistent.
The invention has the beneficial effects as follows:
1. unit cable strand completes the rear directly hanging cable of establishment, and the cross sectional shape of strand keeps good, and precision is higher, without the need to considering large-tonnage, the large volume transport of strand, strand specification limit is larger, can reduce the anchorage quantity of anchorage zone, operating efficiency improves, and saves the costs such as a large amount of manpower and transport.
2. eliminate the links such as lopping, one-tenth dish, packaging, fixing, transport, cost-saving.
3. last anchor processed, during establishment strand, after Dang Suotou involves, anchor not processed, directly draws hanging cable, and after a strand all draws, then at two anchor, now, volume cable system and trailer system can carry out establishment and the traction of a rear strand simultaneously, to save time.
4. sync pulling, the speed of strand workout system and trailer system is unified, and when workout system starts, draw-gear also links startup, reduces manually-operated workload, also can suitably manually adjust.
