Description
Technical field
The present invention relates to bridge construction engineering field, especially a kind of construction method of bridge expanssion joint.
Background technology
Along with the development of urban construction, medium and small bridges gets more and more, and the shrinkage joint construction related to is more and more.Bridge expanssion joint refers to the requirement for meeting bridge floor distortion, usually between two beam-ends, between beam-ends and abutment or on the delivery position of bridge, arranges shrinkage joint.The main a kind of mode adopted is that sandbag is filled at present, and sandbag is filled needs artificial amount large; In work progress, cracky causes sandy soil or foreign material to bleed in shrinkage joint, not easy to clean; And sandbag fill unreal, be easily subjected to displacement, cause both sides, shrinkage joint asphalt compaction degree and planeness not to meet design requirement.
Through retrieval, finds one section of patent document relevant to present patent application: a kind of shallow groove anchorage bridge expanssion joint construction process, notification number: CN1341791, its elder generation establishes both sides, seam place to have step surface at bridge, then carries out surfacing to this two step surface; One group of hole is made a call to two step surface relevant positions are each by the anchor hole position of the stretching device two curb girder body that will arrange, each swivel nut of two groups of expansion bolts and screw rod are placed in each corresponding aperture of step surface, and pour into epoxy cement slurry, and at two step surface surface uniform brushing adhesive sticks; The each anchor hole of two curb girder bodies of stretching device is penetrated on the screw rod of the expansion bolt of each correspondence one by one, then close-fitting is connected with packing ring and nut thereon; Fill up High Strength Concrete at stretching device two curb girder body with in the cavity between corresponding step surface side, stretching device beam body is connected with bridge structure thing by it, and by two groups of expansion bolts, sealing is therein all effectively simultaneously.
Contrasted by technical characteristic, disclosed in above-mentioned document there is relatively big difference in bridge expanssion joint construction process and present patent application in technical scheme.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of construction method of bridge expanssion joint be provided, the method utilize wooden form readily removable except, capable of circulation, not easily displacement and the feature of surfacing; On-the-spot material is utilized to customize wooden form, be mounted to expansion joint position, not only can ensure degree of compaction and the planeness of both sides, shrinkage joint bituminous concrete, and sandy soil, foreign material etc. can not be caused to bleed in shrinkage joint, be a kind of construction method of efficient, reliable, energy-conservation, low cost.
The solution of the present invention is achieved in that
A construction method for bridge expanssion joint, step is as follows:
Step one, before the concreting of bridge engineering abutment, at the vertical or horizontal embedded ribs of the pre-buried bridge expanssion joint in abutment top;
Step 2, making template assembly, width and the shrinkage joint of this template assembly are wide, and height and the basic road surface of template assembly are contour;
Step 3, be placed in template assembly in shrinkage joint embedded ribs on, template assembly lower surface is supported on beam-ends and abutment, and the upper surface of template assembly flushes with basic road surface, and assembled tight firm;
Step 4, on basic road surface and template assembly top asphalt concrete and grinding compacting;
Step 5, along template assembly arranged on left and right sides limit cutting bituminous concrete and instead to open, take out template assembly;
Other reinforcing bars in step 6, colligation shrinkage joint, and on reinforcing bar, weld shrinkage joint shaped steel;
Step 7, to plug-in mounting cystosepiment in the gap formed between the shaped steel of shrinkage joint, then to concreting in shrinkage joint, complete shrinkage joint and all construct.
And described template assembly comprises template and the lumps of wood of rectangular configuration, multiple lumps of wood is installed at the parallel longitudinal interval, lower surface of described template.
And the template size of described template assembly is 75cm × 100cm.
And, in step 4, before asphalt concrete, smear one deck grease at template assembly end face.
Advantage of the present invention and good effect are:
The present invention utilizes existing construction material, draw materials easily, construction cost is low, and technique is simple, speed of application fast, can follow bad utilization after template assembly dismounting; This method easy construction, quick, not only can ensure that shrinkage joint is not filled by sandy soil foreign material in work progress, and can ensure the planeness that has been connected with the asphalt concrete pavement laid after construct in shrinkage joint, the present invention is suitable for popularization, has a extensive future.
