Description
Technical field
The present utility model is related to railway, highway communication engineering, specifically swivel dress in the middle part of a kind of high-altitude pier shaft
It sets.
Background technology
With China's expanding economy, railway and freeway net preliminarily form and constantly improve, from now on railway,
In highway construction, newly-built railway is inevitably encountered, highway needs asking across existing railway and busy highway
Topic, at this moment will be considered as the construction method small to existing line Influence to operation, and rotator construction is a kind of preferable method, but
It is when pier height is higher, will appear swivel in pier bottom swivel, weight is excessive and center of gravity is excessively high, and crank, swivel process is caused to incline
Cover the excessive problem of torque；It then will appear stress system conversion complexity in pier top swivel and construction technology control difficulty be big, especially
It is that body member and the installation of pier top bearing and continuous beam 0# segmental constructions interfere with each other larger, complicated problem.Therefore
Studying a kind of not only economic but also safety construction is very important.
When newly-built railway, highway are needed across existing railway and busy highway, generally use pushing tow or swivel are applied
Work should be selected according to field condition.Rotator construction generally use pier bottom or pier top setting rotor system carry out rotator construction,
But when pier height is higher, will appear swivel in pier bottom swivel, weight is excessive and center of gravity is excessively high, leads to crank, turns process
The excessive problem of tilting moment；It then will appear stress system conversion complexity in pier top swivel and construction technology control difficulty be big, it is special
It is not that body member and the installation of pier top bearing and continuous beam 0# segmental constructions interfere with each other larger, complicated problem.
Invention content
The purpose of this utility model is that in view of the above-mentioned deficiencies in the prior art, providing the higher iron of bridge pier
Road, highway bridge cross over existing railway and busy highway when using rotator construction settling mode.When the higher iron of bridge pier
When road, highway continuous beam, Continuous Rigid-Frame Bridge are needed using rotator construction, since bridge pier is higher, it should not be turned using pier bottom
Body construction, and pier top rotator construction is also more complex, it is contemplated that the safety of structure, the safety of construction save cost, and have invented height
Rotary body device in the middle part of empty pier shaft.
To solve the above problems, the utility model is achieved using following technical scheme：Swivel dress in the middle part of the pier shaft of high-altitude
It sets, including construction rotor system device, lower wall pier shaft and upper disk pier shaft, is installed on high pier middle and upper part position, construction swivel system
Bulk cargo, which installs, to be placed between lower wall pier shaft and upper disk pier shaft.
Pier shaft is respectively set on the lower wall pier shaft and upper disk pier shaft and widens steel construction.
Steel construction rotator construction platform is set up to construction rotor system setting position along high pier.
The upper disk pier shaft, lower wall pier shaft use armored concrete, and the pier shaft widens steel construction and steel construction swivel is applied
Work platform uses steel construction.
The construction rotor system device be it is existing it is a full set of turn facility, including flexural pivot, top rotary table, lower rotary table, slideway,
Spike and trailer system.
It needs to apply using swivel across existing railway, highway in railway, the big span continuous beam of highway, continuous rigid frame bridge
Work, and pier shaft is higher（30m~60m）When, rotary body device in the middle part of the high-altitude pier shaft of the utility model is set, pier bottom can be solved and turned
Body transfer body weight is excessive and center of gravity is excessively high, leads to crank, the excessive problem of swivel process tilting moment；It can solve simultaneously
Certainly the conversion of pier top swivel stress system is complicated and construction technology control difficulty is big, especially body member and the installation of pier top bearing with
And continuous beam 0# segmental constructions interfere with each other larger, complicated problem.
The construction methods such as the utility model is turned compared to pier bottom, pier top turns, in structure feature and the swivel of swivel
Technical difficulty has larger breakthrough, not only more ripe in technology so that swivel spanning existing railway, highway are more
For safety, therefore it is to solve the high pier swivel most economical and feasible scheme of bridge using rotary body device in the middle part of the pier shaft of high-altitude, is one
The novel processing mode of kind.
Rotary body device has the following advantages in the middle part of the pier shaft of the utility model high-altitude：
（1）Rotary body device can effectively solve the higher railway of bridge pier, highway continuous beam, continuous steel in the middle part of the pier shaft of high-altitude
The rotator construction problem of structure bridge.
（2）Widen steel construction dismounting after the completion of construction, bridge pier globality is coordinated, and appearance is preferable.
（3）Engineering can be safely performed more, short time limit, save engineering cost, economical rationality, technological innovation.
