Description
Technical field
The present invention relates to the method and apparatus to build a bridge, and in particular to a kind of based on the accurate of bridge integral replacement technology
Localization method and system.
Background technology
Bridge is influenceed by multiple factors such as traffic loading and natural causes, can engender various problems, for bridge knot
The lasting deterioration of structure, it is necessary to carry out maintenance and renovation, serious then changing superstructure or remove is rebuild.
Traditional remake old bridge mode is rebuild again after Jiu Qiao original places are removed, and this method suffers from traffic
With the limitation in place, apply man-hour requirement and take interim even breaking measure of restricting driving, account for road time length, and to society and traffic impact
Greatly.Simultaneously as the limitation of construction organization, structure is larger by disturbing in work progress, and construction quality is difficult to meet to require.Remove
Difficult outer existing for above-mentioned work progress, also there are a variety of drawbacks in traditional remake old bridge mode.Such as airborne dust is more, noise is big
Cause Heavy environmental pollution；Breaking construction infection passing cars；Vehicle is due to around enforcement fuel consumption increase, the wasting of resources.Meanwhile
The tediously long duration causes the long-term congestion of peripheral path, influences go off daily plan, and public opinion pressure is big.Therefore, take new
Technology reduces the influence to traffic and society, improves speed of application and is increasingly paid attention to by relevant relevant party.
Bridge rapid construction technology is arisen at the historic moment with this demand, wherein with SPMT (self-traveling module Transport Machinery,
Self-Propelled Module Transporters) be nucleus equipment, to bridge superstructure carry out it is whole tear open it is whole build, be this
It is most novel in engineering method, most efficiently a kind of, referred to as bridge integral replacement technology.
The characteristics of rapid construction is disposably to pack " prefabricated tunneling boring bridge superstructure " to after scene, overall drop
Fall, synchronous precision is in place, it is trickle adjustment, be quickly open to traffic.In operation, " prefabricated tunneling boring bridge upper mechanism " uniformly unloads
Load, synchronous stress, overall in place, strict control plane position deviation, it is the difficult point place of the whole project implementation.Traditional beam body is unloaded
The position that makes a decision typically uses " snap the line method ", macroscopical sideline of manual control beam slab, carries out plan-position and the border of center line off normal is controlled
System, error is relatively large, generally 1-2cm；And waste time and energy.
The content of the invention
It is an object of the invention to provide a kind of precise positioning method based on bridge integral replacement technology, solves " prefabricated complete
Section bridge superstructure " drops the plane precise positioning problem of installation, meets《Road Engineering Quality Checking And Evaluation standard》It is right
The requirement of construction plan-position medium line error.
It is a further object to provide a total precise positioning system based on bridge integral replacement technology.
The purpose of the present invention is realized by following technical proposals：
A kind of precise positioning method based on bridge integral replacement technology, this method use a set of precise positioning system, institute
Stating precise positioning system includes locator and at least two lower locating devices at least two, and two upper locators are arranged on bridge
The bottom surface of beam superstructure, two lower locating devices are non-relative to two orthogonal axis of symmetry of the bridge zone on bridge zone
The top of two supporters is symmetrically separately positioned on, the upper locator is correspondingly arranged with the lower locating device；It is described fixed
Position device is provided with inverted truncated rectangular pyramids, the lower locating device is provided with the positioning hole matched with the truncated rectangular pyramids；The step of the precise positioning
Suddenly include：
A, using the top for packing frame all-in-one by the bridge superstructure and being transported to the bridge zone, make two it is described on
The bottom surface of the truncated rectangular pyramids of locator synchronously enters in the opening range of positioning hole of two lower locating devices simultaneously, described in completion
The first positioning of bridge superstructure；
B, the bridge superstructure is slowly fallen, the truncated rectangular pyramids of two upper locators are from two lower locating devices
Positioning hole opening insertion, the internal face of the positioning hole of the truncated rectangular pyramids of two upper locators along two lower locating devices
The center of two lower locating devices is gradually shifted to, the bridge superstructure completes plane position by the precise positioning system
The correction put；
