Description
Technical field
This utility model belongs to technical field of bridge construction, especially relates to a kind of large-span continuous beam deep-water pier pier top
Beam section construction formwork system.
Background technology
At present, China railways bridge construction is in the fast development phase, using advanced design and construction technique, reaches section
Investment-saving, reduction of erection time are it is ensured that the target of safety is always the result that engineering circles are pursued.Wherein, in large span, deep-water bridge
Construction aspect, design theory, building technology and equipment aspect have reached or close to advanced international standard.For example in Nanning railway pivot
Knob increases newly in the grand bridge Construction of continuous beam of the new Yongning in two wires river in Guangxi river, and bridge main, across reaching 168m, is domestic current single-line railway bridge
Maximum span in beam.This bridge deepwater foundation construction security risk is high, and quality control difficulty is big；Especially carry out exposed under water
During the excavation of basement foundation, because bridge is against both wired, main pier is located in Yong Jiang (II grade of navigation channel of planning), and the depth of water reaches 18m,
Both wired (i.e. existing railway line) operation and river in Guangxi river Navigation in Navigable safety should be guaranteed, ensure construction period, quality, safety again
On the premise of, select rational construction technical schemes just particularly important.Meanwhile, the construction to bridge top continuous beam, needs to adopt
Merogenesis section constructing method, its cantilever construction will experience the mistake that "T"-shaped cantilever pouring sections (i.e. T structure cantilever beam section) forms girder
Journey.This bridge main span reaches 168m, arm length, and the process of system transform to be experienced, the internal force of girder and linear all can be with construction
Progress and be continually changing.Because beam body span is big, sections is many, has higher requirement to beam body alignment control, such as controls not
Good, not only affect the presentation quality of beam body, the prior operation that can affect beam body.
Although deepwater pier Double-Wall Steel Boxed Cofferdam foundation construction and large-span continuous beam construction have the construction of comparative maturity at home
Precedent, but include deep water intectate exposed bedrock, deepwater foundation construction under water, and with existing Business Line route distance
Only 30m, or relatively more rare, and also bridge main reaches the continuous beam cantilever casting construction of 168m across span, at home still very
Rare.Especially the beam section (hereinafter referred to as deep-water pier pier top beam section) being supported on deep-water pier in T structure cantilever beam section is entered
During row construction, difficulty of construction is very big.Deep-water pier pier top beam section is also referred to as 0# beam section, and it is the beam section constructed at first, this beam
Section is full bridge structure stress is the most complicated, difficulty of construction is maximum one section, generally carries out cast-in-place applying using bracket support template system
Work.But because above-mentioned deep-water pier pier top beam section is supported on deep-water pier, the difficulty of construction of pier top bracket is larger, simultaneously because of bridge
Beam main span span reaches 168m, thus the construction quality of deep-water pier pier top beam section is most important.Therefore, a kind of structure need to be designed
Simply, a large-span continuous beam deep-water pier pier top beam section construction module system reasonable in design and that easy construction, using effect are good
System, energy is easy, be quickly fixedly installed in deep-water pier pier top, and stressed effect is good, is provided that firm support.
