The specific embodiment:
Below in conjunction with accompanying drawing and example, the present invention is further described.
1, vertical guide sets up the cat road
，Mao road 1 You Mao road track cable, crossbeam, manrope, veil, horizontal compositions such as wind resistance steadying line 7, anchoring adjustment System as shown in Figure 10 and Figure 11.Cat road track cable 1 can be with three across isolating construction.Two end bays are respectively established a width and are merged the cat road.In across main push-towing rope due to needs through the space transfer process, so the Zhong Kuamao road adopts two width independence cat roads.
2, vertical guide braided cable
Main push-towing rope 2 is arranged on 1 top, cat road, and main cable unit cable strand adopts vertical guide erection technique comparative maturity, is divided into general Strand Erection and Datum Strand Erection two classes.Main construction sequence is: the strand traction; On strand, carry, traversing shaping enters saddle; The strand sag adjustment; The anchor span tension adjustment.First set up Datum Strand, after observing, adjusting, then take Datum Strand as benchmark sets up general strand.
3, the tight cable of vertical guide
Tight cable work must be carried out in two steps, i.e. pretension cable and formal tight cable.The method that binding strap on strand adopts Jin Lan limit, limit to remove, a unsuitable complete removal.Formal tight cable adopts special-purpose tight cable machine that main push-towing rope is made into to circle.The direction of formal tight cable should be carried out to the king-post direction from span centre, and end bay is carried out to the king-post direction by anchorage.The schematic diagram that Fig. 1～Fig. 4 is empty cable state main push-towing rope.
4, interim cord clip, interim hoist cable are installed, permanent cord clip vertical guide initial alignment
Multipair interim cord clip and interim hoist cable 3 are installed in vertical guide.Interim cord clip, hoist cable and permanent cord clip, hoist cable be not all at same position, and length is also different.Consider it is interim member, the strength of materials can be considered suitable reduction.Interim cord clip is arranged on main push-towing rope 2, and interim hoist cable 3 one ends are connected with main push-towing rope 2 by interim cord clip, and the other end is connected with Bridge beam 4.Because the permanent hoist cable of this bridge is the Spatial Cable face, this just requires permanent cord clip accurately to locate.First carry out permanent cord clip initial alignment, the three dimensional space coordinate accurate positioning, the cord clip bolt is just twisted, and tonnage is less, does not make the cord clip slippage.Permanent cord clip is only pursued and installs to tower top by span centre and anchorage place.
5, in across the multipair interim drag-line of symmetrical stretch-draw, will in be flared to across main push-towing rope is traversing that to approach into bridge linear
Adopt multipoint method, as required, in across the multipair interim drag-line of symmetrical stretch-draw, will in be flared to across main push-towing rope is traversing that to approach into bridge linear, the space angle of controlling cord clip and hoist cable with become the bridge angle more approaching, when guaranteeing the hoist cable installation, can penetrate in the girder anchor tube.This process is the key of cable system construction method of spatial self-anchored rope-suspension bridge.Determine some, several to interim drag-line, need obtain by analog computation.Purpose is by several stretch-draw to interim hoist cable, and after making main push-towing rope traversing, the hoist cable lateral slip angle can meet the required precision of design.According to span, the about 50m of spacing left and right between general interim hoist cable.Fig. 5 is that interim hoist cable is arranged schematic diagram, and Fig. 6～Fig. 9 is into the schematic diagram of bridge state main push-towing rope.
6, permanent cord clip angle accurately locate, permanent hoist cable stretch-draw anchor, saddle pushing tow
The about 10m of permanent hoist cable spacing left and right, the every corresponding permanent cord clip in hoist cable upper end.Main push-towing rope is traversing be flared to approach into bridge linear after, just can carry out the accurate location adjustment of permanent cord clip.Under this state, due to depth-width ratio, higher near the cord clip position of king-post, with the lateral angles of girder anchor point, with becoming the bridge state, approach, and the cord clip position of close span centre is lower, with the lateral angles of girder anchor point with become bridge state difference distance also very large.Therefore, the tension sequence of hoist cable should carry out stretch-draw to the span centre direction from king-post 6, can make the differential seat angle between cord clip otic placode and hoist cable meet required precision.For eliminating the impact of the hoist cable of stretch-draw on other hoist cable own, the accurate adjustment of cord clip angle must be carried out after a upper hoist cable stretch-draw is complete simultaneously.
By the gauge point of doing on main push-towing rope in advance, use universal bevel protractor, measure the angle that now main push-towing rope reverses, according to survey data and corrected Calculation value, cord clip otic placode angle is carried out to accurate adjustment.The result of calculating according to work progress system converting analogue, Space Nonlinear and the requirement of hoist cable safety factor due to main push-towing rope, have the part rope to need the spreading anchoring in stretching process.Along with the stretch-draw of hoist cable, to becoming, bridge is linear to be drawn close gradually for main push-towing rope linear, and the cord clip angular deviation is also more and more less.Excessive for preventing the hoist cable lateral angles, be provided with stiffening ring device 8 on each permanent cord clip, can regulate the space angle of cord clip by drag cable, make in be controlled at ± 2 degree of hoist cable lateral slip angle in stretching process.
7, system conversion, full-bridge Suo Li adjust
In system conversion process, along with the stretch-draw of permanent hoist cable, the Suo Li of interim hoist cable is decreased to zero gradually, at this moment interim hoist cable can be removed.Permanent one-phase is to hang cable force and linear dual control, with Suo Liwei master.Mainly by regulate the order and the number of times that hang cable force and the permanent rope of stretch-draw temporarily, solve.Permanent one complete, after the de-frame of girder steel, carry out the full-bridge adjustment to hanging cable force as required.The permanent two-stage, to hang cable force and linear dual control, take linear as main.Be now accelerating construction progress, can first carry out the construction of deck paving and the second bridge deck main cable protection system, carry out as required funiculus posterior medullae spinalis power and always adjust after becoming bridge.
8, main push-towing rope twines silk, protection, the ancillary works construction
