The design feature of the compound Hanging basket on front support of the utility model single cable plane is lain also in：In the rear suspension of box beam bottom plate
Walking dolly, the walking dolly are to be arranged on the central track of Hanging Basket guy rope longeron as traveling slideway；Among two panels
Suspender belt is set respectively on the lower boom of English truss, the suspender belt is attached with Hanging Basket guy rope longeron using bearing pin, Hanging Basket
Bottom bearing platform is suspended in below English truss, and the top of suspender belt sets piston shoes, utilizes piston shoes and two panels middle triangle truss
Lower boom be connected；Thrusting slip jack is set in the front end of two panels middle triangle truss, utilizes the thrusting slip thousand
Jin top drawing piston shoes, so as to drive cradle bottom bearing platform integrally to move forward.
Compared with the prior art, the utility model has the beneficial effect that：
1st, the utility model successfully solves single rope on the triangular truss structure in the compound Hanging basket on front support of single cable plane
The big technical barrier of face cable-stayed bridge Hanging basket on front support lateral stability control difficulty, while it is used as suspended basket by the use of English truss
Draw-gear, it is rational in infrastructure, safe and reliable, so simplify construction, shorten the duration, reduce cost.
2nd, the utility model is suited measures to local conditions, Hanging Basket makes full use of girder 0# blocks, the support and main girder construction of girder 1# blocks
Trestle is as platform for lining, and the installation method integrally lifted by jack solves the Hanging Basket on river course and installs difficulty in place
Topic, reduces the security risk of overlength large-scale component upper air installing installation, while also ensure that the quality of Hanging basket on front support installation.
3rd, the compound Hanging basket on front support guy rope longeron front end arc head top surfaces improvement of single cable plane is arranged in the utility model
Slab construction, the first arch section of arc is down translated, avoid to effect Hanging Basket arc head and stay cable force converting means
Put the problem with Cast-in-Situ Segment interference.

Embodiment
Referring to Fig. 1 and Fig. 2, the structure type of the compound Hanging basket on front support of single cable plane is in the present embodiment：Set in bridge floor
Four English trusses, carried with preceding suspension rod 11 of the office in the two panels lateralis truss 1 in outside for cradle bottom bearing platform 12
It is in vertical rigid support for one, auxiliary bears the load of Hanging basket on front support bottom bearing platform, safeguards Hanging Basket lateral stability；
The haulage gear of suspended basket is used as using interjacent two panels middle triangle truss 2；To adapt to end bay Cast-in-Situ Segment and closure segment
The needs of construction, the arc head top surfaces of Hanging Basket guy rope longeron 3 change into what is be horizontal by " bending upwards type " in traditional structure
Slab construction, when this form can effectively prevent that maximum cantilever section and closure segment from constructing, first formed with Cast-in-Situ Segment of arc disturbs.
In specific implementation, Hanging Basket guy rope longeron 3 sets two panels altogether, Hanging Basket guy rope longeron 3 be welded using steel plate it is whole
Body formula box-structure, the length of Hanging Basket guy rope longeron 3 is set to meet the installation requirement of suspended basket and suspension cable 6.
As shown in figure 1, in the rear suspension walking dolly 7 of box beam bottom plate, walking dolly 7 is indulged with being arranged on Hanging Basket guy rope
The central track of beam 3 is traveling slideway 15, to ensure the stability of the compound Hanging basket on front support traveling of single cable plane, in twice
Straining beam is welded between Hanging Basket guy rope longeron 3 and forms overall structure, traveling slideway is arranged on the top surface of straining beam.
Suspender belt 8 is set respectively on the lower boom of two panels middle triangle truss 2, suspender belt 8 and Hanging Basket guy rope longeron 3 are used
Bearing pin is attached, and cradle bottom bearing platform 12 is suspended in the lower section of English truss, and the top of suspender belt 8 sets piston shoes 9, utilized
Piston shoes 9 are connected with the lower boom of two panels middle triangle truss 2；In the front end of two panels middle triangle truss 2, thrusting slip is set
Jack 10, piston shoes 9 are pulled using thrusting slip jack 10, so as to drive cradle bottom bearing platform 12 overall to reach
It is dynamic.
The installation method of the compound Hanging basket on front support of single cable plane is in the present embodiment：
Girder 0# blocks 13 and girder 1# blocks 14 are constructed using support cast-in-place, and the support of girder 0# blocks 13 and girder 1# blocks 14 is
Using the modular support being made up of bowl fastening type steel pipe scaffold 4a and falsework 4b, falsework 4b top surface absolute altitude and main girder construction stack
The top surface absolute altitude of bridge 5 flushes, and falsework 4b is linked to be entirety with existing main girder construction trestle 5；First with bowl fastening type steel pipe feet hand
Frame 4a completes the cast-in-place construction of girder 0# blocks 13 and girder 1# blocks 14, and completes the installation of suspension cable 6；Then remove bowl fastening type steel
Pin hand cradle 4a, the integral assembling of Hanging Basket is completed on main girder construction trestle 5 and falsework 4b, recycle thousand be arranged on bridge floor
