Description
Technical field
This utility model belongs to technical field of bridge construction, particularly relates to ultra-wide view picture formula box girder with variable cross section 0# block pile knot
Box-like temporary consolidation system.
Background technology
Along with China Investment in Basic Facilities for Traffic builds steady growth, road and bridge construction achieves and develops rapidly, greatly across
Degree bridge application is more and more extensive, and variable cross-section continuous beam is increasingly becoming the main flow bridge type crossing over the barrier such as river, road.Outstanding
Arm casting method and bracket subsection casting method are main two kinds of construction methods of box girder with variable cross section, and the emphasis that 0# block is constructed especially
With difficult point position.Before Hanging Basket cantilever or segmented support cast-in-place, it is necessary to the continuous pier of temporary consolidation, beam body is converted into static determinacy knot
Structure.
For variable cross-section continuous beam 0# block temporary consolidation, generally use Support Method, cushion cap top steel-pipe pile temporary consolidation, pier
Top, without support temporary consolidation etc., is respectively arranged with its characteristics and available field, and technique is the most ripe.For Support Method, due to bracket basis
Part utilizes cushion cap, and part is ground foundation, is easily formed bigger differential settlement, and is not subject in construction the unbalanced moment produced,
Reduce safety.Steel pipe column for cushion cap top consolidates system, owing to making full use of cushion cap space (or at direction across bridge cushion cap two
Side arranges cast-in-place bracket) arrange steel pipe column support system, apply in general to the following bridge of deck-siding 15m.For pier top supportless
Temporary consolidation technique, the first size to pier stud have certain requirement, otherwise cannot carry out pressure block, anchoring temporarily bundle in pier top
Layout, and when No. 0 block is long, this consolidation technique stress system cannot effectively support.In sum, for ultra-wide
(more than 30m) box girder with variable cross section 0# block, existing temporary consolidation technique all can not reach its construction requirement.
Summary of the invention
Present invention aims to the whole secondary formula variable cross-section continuous beam of ultra-wide (more than deck-siding 30m, cushion cap pier stud size
For broad box girder cross section, smaller), existing 0# block consolidation technique can not effectively solve ultra-wide section temporary support and
Solidification problem, on the basis of prior art, it is provided that the 0# block that a kind of cast-in-situ bored pile and steel pipe support post i.e. pile combine is solid
Knot body system, i.e. need to arrange steel pipe support post requirement at the outer ground of cushion cap for ultra-wide box beam direction across bridge, use and first arrange boring
Bored concrete pile foundation and reinforced concrete pile cap connect the design of steel pipe column again, ask solving steel pipe column support system differential settlement
Topic, it is ensured that construction safety is reliable.
In order to realize above-mentioned purpose, this utility model have employed following technical scheme:
Ultra-wide view picture formula box girder with variable cross section 0# block pile convolution temporary consolidation system, including main cushion cap, described main cushion cap
On be provided with continuous pier stud, be respectively arranged with row's steel pipe support post along continuous pier stud both sides, described steel pipe support post part is pacified
Being contained on main cushion cap, at least four steel pipe support posts are arranged on outside main cushion cap surrounding, these four steel pipe support posts position respectively
Under the outboard web of box beam 0# block base plate.
As preferably, being provided with 4 interim bored pile foundations outside described main cushion cap surrounding, described interim boring fills
Note pile foundation upper end is provided with interim cushion cap, is arranged on four steel pipe support posts outside main cushion cap surrounding and is fixed on 4 temporarily
On cushion cap.
As preferably, described steel pipe support column bottom is provided with pre-buried finish rolling twisted steel, and pre-buried finish rolling twisted steel is arranged
There is vertical finish rolling screw thread presstressed reinforcing steel, between pre-buried finish rolling twisted steel and vertical finish rolling screw thread presstressed reinforcing steel by branch sleeve even
Connect.
As preferably, described main cushion cap and interim cushion cap being embedded with steel plate, steel pipe support post is directly fixed by steel plate.
As preferably, laterally attached between described steel pipe support post have laterally attached beam, is horizontally connected with lateral connection beam.
Compared with prior art, the invention has the beneficial effects as follows:
1., by designing interim bored pile foundation and interim cushion cap, overcome ultra-wide monoblock type variable cross-section and connect box beam
The uneven subsidence of the outer steel pipe support post of 0# block cushion cap.
2. simple in construction, technical maturity, stress is clear and definite, easy construction.
3. make full use of main pier bearing platform to participate in, outside stress, only needing to arrange 4 large diameter boreholes outside cushion cap surrounding simultaneously
Bored concrete pile foundation, so that it may solving the temporary consolidation of ultra-wide integrated box girder (more than 30m), relatively economical, quality safety is reliable.
