Description
Technical field
The utility model is related to construction engineering technical field, more particularly to a kind of rigid frame bridge non-truncated pier stud climbing structure.
Background technology
Traditional indeterminate bridge jacking engineering carries out again the spy of jacking with releasing after the conversion stress system that is rigidly connected
Point, had both destroyed former pier stud and had carried system, can not protect again fully ensure that releasing be rigidly connected during construction safety, and subsequently
Accurate Prediction is unable to bridge mass action counter productive, is unfavorable for the protection to former bridge structure.
Utility model content
To solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of not injury of primary structural-load-carrying capacity, applies
Work process is simple, short time limit, recyclable, reusable rigid frame bridge non-truncated pier stud climbing structure.
Rigid frame bridge non-truncated pier stud climbing structure of the present utility model, including jack, steel pipe pier and precutting trough, institute
The two ends for stating steel pipe pier are provided with ring flange；The ring flange of the steel pipe pier bottom fixed by fixture and billet and
The bottom of the billet is provided with precutting trough；Fix described very heavy by fixture on ring flange at the top of the steel pipe pier
Top, at the top of the jack billet is fixed with.
Further, it is additionally provided with for the non-slipping block of spacing jack on the ring flange at the top of the steel pipe pier.
Further, the fixture is bolt.
Further, the steel pipe pier includes at least end to end steel pipe pier of two-stage.
Further, the length of the steel pipe pier is 5-6m.
Further, two end side surfaces of the steel pipe pier are additionally provided with floor.
Further, the billet surrounding of the steel pipe pier bottom is fixed on the ground by cast-in fixing bolt.
Further, the pre-cut slot thickness is 5～10cm.
By such scheme, the utility model at least has advantages below：1) applied range；2) do not damage original structure to hold
Loading capability；3) work progress is simple, short time limit；4) recyclable, reuse；5) quality is easily guaranteed that.
The utility model in the face of original basis surrounding on ground by applying precutting trough so that original basis are separated with surrounding soil,
Realize the target of jacking by arranging interim steel pipe pier again, especially with hydraulic synchronous system jack jacking is controlled, eliminate
Relative settlement between each pier stud, on the basis of the former pier stud bearing capacity that adequately protects, former pier stud jacking bridge is not blocked in realization
Target；Do not block pier stud jack lifting technique and block pier stud process is simple than traditional, it is not necessary to destroy original structure, maximum possible is protected
Shield original structure bearing capacity, and face steel pipe, girder steel, jack etc. can be with Resource recovery.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
