Description
Technical field
The present invention relates to the suspension cable field of bridge, the direct volume rope that is specially a kind of main rope of suspension bridge strand is hung Suo Fangfa.
Background technology
The erection construction of main rope of suspension bridge mainly contains two kinds of methods at present: aerial braided cable method (AS) and prefabricated strand method (PPWS).During the operation of AS method, utilize a rotating disk and trailer system that individual wire is suspended on the bridge, rotating disk shuttles and sets up steel wire in the bridge two ends, because the steel wire quantity that main push-towing rope unit strand includes is very many, can reach hundreds of, rotating disk needs back and forth operation could satisfy the establishment of a main push-towing rope unit strand for hundreds of times like this, and setting up of a main push-towing rope needs tens up to a hundred main push-towing rope unit strands to form, that is to say that the main push-towing rope with a suspension bridge of AS method establishment needs rotating disk tens thousand of back and forth times, often need the time of 1 year even several years, expend a large amount of time and manpower, work difficulty is big during AS method operation simultaneously, it is big influenced by weather etc., the strand precision of establishment is low, and each steel wire unbalance stress in the rope causes indivedual steel wire stress to concentrate, be unfavorable for the efficient high life operation of strand, cause huge waste.During the operation of PPWS method, in factory, steel wire is made into strand in advance, then strand is transported to the bridge construction scene and hangs the rope installation.PPWS method strand is made the precision height, and installation period is short, and is easy for installation, is subjected to weather effect less.But the PPWS method need be considered the transportation of strand, needs to make a large amount of logistics haulage devices; Because the strand tonnage is all bigger, considers transportation problem, the specification of strand can only be reduced to tens to 100 multifibres; Have to set up anchorage when the strand specification reduces to make bridge construction, cause the anchorage pedestal long-pending huge, increased the consumption of goods and materials at the bridge two ends; Because the most of environment in bridge construction building site are abominable, particularly mountain road transportation, the strand transportation of hundreds of ton is difficulty very.
Summary of the invention
In order to overcome the defective of prior art, a kind of strand precision height, long service life, short construction period, the consumption of materials is few, transport difficulty is low suspension bridge suspension cable erection method are provided, and the direct volume rope that the invention discloses a kind of main rope of suspension bridge strand is hung Suo Fangfa.
The present invention reaches goal of the invention by following technical solution:
A kind of on-the-spot rope of directly compiling of main rope of suspension bridge strand is hung Suo Fangfa, comprise the planning unit strand, during the planning unit strand, steel wire is emitted from thread discharge disk, enter wire sub-panel through guide frame, sending into closing device after wire sub-panel divides silk closes up, again after the shaping of shaping wheel by traction unit machine travel unit, after wrapped machine is wrapped, be delivered to transition apparatus, finish the planning unit strand, it is characterized in that: also comprise the establishment equipment that is provided with, the traction unit strand, the hot-cast anchor, the cooling ground tackle, strand ground tackle and linear these 6 steps of adjusting are installed, the planning unit strand finish establishment equipment is set after and carry out before the traction unit strand.When establishment equipment is set, an end of hanging rope job site suspension bridge bridge tower at main push-towing rope is provided with the establishment district, in the establishment district, establishment equipment is set, establishment equipment comprises thread discharge disk, mistake guide frame, wire sub-panel, closing device, shaping wheel, traction unit machine, wrapped machine and the transition apparatus that is arranged in order, transition apparatus is made up of fixed pulley, movable pulley and pillar, fixed pulley is fixed on the pillar, movable pulley is enclosed within on the pillar and along pillar and slides up and down, fixed pulley and movable pulley are staggered, and the unit strand is embedded in the race of fixed pulley and movable pulley successively.During the traction unit strand, the unit strand is drawn to the top of suspension bridge bridge tower by hoist engine, the unit strand is drawn successively by cat head crawler belt and apparatus for shaping, after in stride traction to another suspension bridge bridge tower.During the hot-cast anchor, the suspension bridge bridge tower at two ends is provided with hot-cast anchor platform respectively, and casting chill casting material carries out the hot-cast anchor to strand.During the cooling ground tackle, the chill casting material is solidified strand two ends, the unit cooling of having finished the hot-cast anchor.When the strand ground tackle is installed, the strand ground tackle at strand two ends, unit is separately fixed at the anchorage place at suspension bridge two ends.During linear adjustment, according to linear with the 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 of suspension bridge design etc.
The on-the-spot rope of directly compiling of described main rope of suspension bridge strand is hung Suo Fangfa, it is characterized in that: after establishment equipment is set, planning unit strand and traction unit strand carry out simultaneously, be promptly to begin the traction unit strand after the front end of steel wire is finished the planning unit strand, the planning unit strand is proceeded in the rear end of steel wire, and during the planning unit strand when traction unit speed of steel wire and traction unit strand the traction unit speed of unit strand be consistent.
The invention has the beneficial effects as follows:
1. the unit strand is finished the establishment back and is directly hung rope, and it is good that the cross sectional shape of strand keeps, and precision is higher, need not to consider large-tonnage, the large volume transportation of strand, the strand specification limit is bigger, can dwindle the anchorage quantity of anchorage zone, operating efficiency improves, and saves costs such as a large amount of manpowers and transportation.
2. omit links such as lopping, one-tenth dish, packing, fixing, transportation, saved cost.
3. make anchor at last, during the establishment strand, do not make anchor after Dang Suotou involves, directly rope is hung in traction, after a strand all draws and finishes, again at two system anchor, at this moment, compiles cable system and trailer system and can carry out the establishment and the traction of a back strand simultaneously, to save time.
4. sync pulling, strand establishment system unifies with the speed of trailer system, and when the establishment system started, the draw-gear startup that also links reduced manually-operated workload, also can suitably manually adjust.
