Description
Technical field
The present invention relates to a kind of hanging basket cantilever method construction, in particular to a kind of curve low-pylon cable-stayed bridge Hanging Basket is short
Special arrangement and traversing construction method in small 0# beam sections.
Background technology
At present, Hanging Basket cantilever pouring construction has been a kind of ripe cast-in-place construction technique, and the design and installation of Hanging Basket are these
The core of technique, the installation spelling of Hanging Basket is the whole substantial first step of Hanging Basket cantilever construction for concrete operations,
It is a most important link.When some specific type bridges are run into, traditional cradle assembly scheme generally requires to make
Change can adapt to construction.Especially in some bridges, 0# section box girder length is shorter, and design Hanging Basket main longitudinal grider because
Some cause specifics must are fulfilled for certain length condition, and the solution generally directed to this contradiction is forced to change Hanging Basket
Form is processed by the way of being connect using first having no progeny main longitudinal grider, and construction is extremely bothered.
The content of the invention
It is short and small it is an object of the invention to solve curve low-pylon cable-stayed bridge 0# beam sections, Hanging Basket cannot normal mounting problem,
A kind of curve low-pylon cable-stayed bridge Hanging Basket interlaced arrangement and traversing construction method are provided herein, existing Hanging Basket is made full use of to reach
Purpose, in the case where construction input is relatively fewer, solves 0# sections of Hanging Basket of curve low-pylon cable-stayed bridge and be unable to normal mounting and ask
Topic.

Track is installed below drop-over steel plate, and the coating lubricating oil on drop-over steel plate；
（5）Cross track is installed：Track has been transversely mounted it and has anchored in the position of rear anchor dolly, and rear anchor dolly has been rotated
90 ° are anchored on cross track；
（6）Reaction frame is installed：Reaction frame is welded at Hanging Basket fulcrum, reaction frame is welded on pre-buried good steel plate；
（7）Jack is installed：Hydraulic jack is installed at central bearing point after being welded reaction frame；
（8）Anchor constraint, makes rear anchor be separated with beam body after dismounting, transfers force on rear anchor dolly, and in each rear anchor point
One 5t chain block is respectively installed；
（9）Anchor point chain block tensed with long rails at jack pushing tow fulcrum simultaneously after, makes Hanging Basket together with longitudinal rail
Road slowly slides transverse translation to design attitude on drop-over steel plate, anchor fining twisted steel and is anchored after then installing；
（10）Anchor point cross track after dismounting, and move long rails afterwards and anchor, anchored after rear anchor dolly is rotated by 90 °
On long rails；
（11）Edge of a wing skid beam suspension rod is reinstalled in normotopia, and is anchored；
（12）Anchor after dismounting, two sets of Hanging Baskets symmetrically move forward to No. 2 beam section positions and anchor on request, complete No. 2 beam sections and hang
Basket is in place, into next procedure construction.
Curve low-pylon cable-stayed bridge Hanging Basket of the present invention is staggered installation of and traversing construction method, in the traversing playback of Hanging Basket
When, anchor point carries out track and dolly is rotated by 90 ° after Hanging Basket, and it is rolling friction to become sliding friction.
In the traversing playback of Hanging Basket, many methods of hydraulic jack are controlled using same oil pump and oil meter combination banked direction control valves
Control jacking force, it is ensured that each point stress equalization, prevents larger internal force influence Hanging Basket resistance to overturning.
The advantage of the invention is that：Compared with prior art, the beneficial effects of the present invention are：
（1）The cost-effective, duration：After being such as staggered installation of using Hanging Basket, remove Hanging Basket reinstall, it is necessary to artificial, material,
200,000 yuan of the expenses such as plant equipment, reinstalling Hanging Basket need to be with 20 days time, it is necessary to pay site operation expense and administration fee
Totally 10 ten thousand yuan.And after using this construction technology, it is only necessary to 20,000 yuan of the expense such as artificial, material, plant equipment, the engineering time only needs 2
It is, it is necessary to pay site operation expense and administration fee less than 10,000 yuan.
（2）Hanging Basket is staggered installation of and whole lateral moving construction stress is clear and definite, and safe and reliable, economic and practical, technology is easily mastered,
The construction period can be shortened and reduced investment outlay, be a kind of construction method being worthy to be popularized.
