The anchorage of suspension bridge both sides,
The king-tower both sides are respectively fixed with one first anchor, pass through between two the first anchors of same king-tower
Being connected to drawing device in king-tower is embedded in, a main span load-bearing is connected between two relative the first anchors between two king-towers
Rope；
The anchorage is provided with the second anchor, the first anchor of second anchor king-tower relative with its
It is fixedly mounted between putting and is connected with end bay track cable.
On the basis of above-mentioned technical proposal, main span track cable and the second anchoring dress by first anchor
The tune rope device for adjusting track cable line style is equipped with the end bay track cable for putting side.
On the basis of above-mentioned technical proposal, described pair load be set to be embedded in king-tower to draw finish rolling deformed bar.
The present invention also provides a kind of construction method in above-mentioned suspension bridge segmented cat road, is comprised the following steps in method：
S1, on the king-tower of suspension bridge both sides main cable saddle is installed, is installed on the anchorage of both sides and dissipate cable saddle；It is subsequently mounted tower top door
Frame, scattered cable saddle door frame, the first anchor, the second anchor and tune rope device；
S2, erecting guide rope, form it into unidirectional reciprocating-type tractor system, and two end bays are first installed using the trailer system
Track cable, then installs main span track cable, finally installs door frame rope and hauling rope；
S3, installation cat road track cable displacement steel frame construction, cat road surface layer structure and horizontal day bridge construction.
On the basis of above-mentioned technical proposal, when first anchor is installed, drawing device is carried out by setting
Prestretching.
On the basis of above-mentioned technical proposal, the LFM signal of the main span track cable and the end bay track cable enters respectively
OK.
On the basis of above-mentioned technical proposal, also include in the step S2, by adjusting rope device by the linear tune of guide cable
Design linear under whole to empty strand state.
On the basis of above-mentioned technical proposal, also include in the step S3, by adjusting rope device respectively by main span load-bearing
Rope and end bay track cable LFM signal are to design attitude.
Compared with prior art, the advantage of the invention is that：
(1) segmented Mao Daozhongmao roads track cable of the invention is disconnected at king-tower, and end bay can be separated with across track cable
Installed and debugged so that track cable is influenceed small by temperature and cutting length, site operation tissue is simple, efficiency of construction is high,
With very strong applicability and economy.
(2) segmented Mao Daozhongmao roads track cable of the invention disconnects at king-tower, greatly simplify cat road rope set up and
LFM signal operation, shortens the erection time, saves construction costs, while it is more simple to arrange tower top, facilitates main rope of suspension bridge
Strand Erection is constructed, while later stage cat road structural demolition more facilitates, while cat road track cable is being installed and is using process center line
Shape adjustment is more convenient.
