Description
Technical field
The present invention relates to Arch Bridge Construction fields, be specifically it is a kind of using end bay pressure Tasso as buckling and hanging system dorsal funciculus
Construction method.
Background technique
It when deck type or half-through arch bridge are constructed, generallys use and withholds integrated structure type, therefore it presses Tasso and button
Extension system is all set on same king-post.Shown according to structural finite element analysis and previous Arch Bridge Construction actual measurement data
As buckling and hanging system is constantly installed, Sarasota absolute deviation of tower top under identical hoist operating condition is constantly reducing, but due to pressing tower
Rope is different from buckling and hanging system effect, now usually accounts for as mutually independent system when arch bridge conceptual design.This side
Formula will increase steel strand wires dosage and when anchor case number, especially Large Span Structure of Arch bridge construction, due to buckling and hanging system anchor case number compared with
It is more, it is more difficult that anchor case arrangement is limited by king-post space.
Summary of the invention
Therefore, in order to solve above-mentioned deficiency, the present invention provide herein it is a kind of using end bay pressure Tasso as buckling and hanging system back
The construction method of rope；When solution conventional cable lifting pressure Tasso and buckling and hanging system are designed as mutually independent system, by
It is repeated in its partial function, causes material utilization amount to increase, anchor case difficult arrangement and cumbersome problem.
The invention is realized in this way a kind of construction method that buckling and hanging system dorsal funciculus is doubled as using end bay pressure Tasso is constructed,
It is characterized by: directly also serving as part buckling and hanging system dorsal funciculus using end bay pressure Tasso, buckling and hanging system dorsal funciculus quantity is reduced to play
Purpose；
Its operating procedure is as follows:
(1) CABLEWAY ERECTION SYSTEM is installed: being installed CABLEWAY ERECTION SYSTEM, is needed to install pressure Tasso according to Structure Calculation, and by calculating
Tension carries out tensioning operation to pressure Tasso, and end bay pressure Tasso tension is T1 at this time, and middle cross-pressure Tasso tension is T1 '；
(2) the 1st ~ the N-1 sections of arch rib installations:
The 1st ~ the N-1 sections of rib-lifting sections are successively lifted, and set gradually buckling and hanging system knotted rope and dorsal funciculus as required, according to design
Load tensioning buckling and hanging system knotted rope and dorsal funciculus, it is ensured that arch rib line style and design line style are coincide；
(3) N sections of arch rib installations: N sections of arch ribs of lifting to installation site install the road N buckling and hanging system knotted rope, according to design lotus
It carries simultaneous tension N road knotted rope and end bay presses Tasso dorsal funciculus, complete the installation of the last one rib-lifting section；Due to tensioning front across
Pressure Tasso dorsal funciculus has had tension T1, therefore presses Tasso dorsal funciculus category two times tensioning, its tension is T2 after tensioning；
(4) restore pressure Tasso to original state: arch rib needs to remove buckling and hanging system after being installed, the unloading of the road N knotted rope
When, opposite side cross-pressure Tasso should be synchronized and unloaded, until its tension restores from T2 to T1, then remove the road N knotted rope, then according to
It is secondary to remove remaining button, dorsal funciculus.
The present invention has the advantage that the construction method is directly using pressure Tasso dorsal funciculus as the last one rib-lifting section
Buckling and hanging system dorsal funciculus has following features；
Its 1: relatively conventional " button one is hung " structural system, the invention patent unilateral side rib-lifting section can reduce by one of dorsal funciculus, drop significantly
Low dorsal funciculus steel strand wires dosage, saves engineering cost；
Its 2: save one of knotted rope installation procedure, accelerate the engineering construction duration, reduce high-altitude application risk；
Its 3: single king-post reduces a dorsal funciculus anchor case, saves Sarasota space, reduces Sarasota load, increasing structure can
By degree.

Specific embodiment
Below in conjunction with attached drawing 1- Fig. 3, the present invention is described in detail, technical solution in the embodiment of the present invention into
Row clearly and completely describes, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
Every other embodiment, shall fall within the protection scope of the present invention.
The present invention provides a kind of construction method for pressing Tasso to double as buckling and hanging system dorsal funciculus using end bay by improving herein；
As shown in Figure 1, system structure: by cable crane 1, anchorage 2, Sarasota 3, end bay pressure Tasso 4, middle cross-pressure Tasso 5, knotted rope 6,
Dorsal funciculus 7 and arch rib 8 form, and core is that end bay pressure Tasso is directly utilized to also serve as part buckling and hanging system dorsal funciculus, are subtracted with playing
