Abstract
The invention relates to a one-time leveling method for the installation of a large bridge support, the bridge support, as an important constituent part of a beam bridge structure, is a force transferring device arranged at the support location of a bridge-span structure and a bridge pier or the supporting position of a bridge abutment. As the large bridge support limits the operating space on the top of a pier column, the support is difficult to meet the leveling demand during construction. At present, dry hard mortar is used as an anchorage leveling grouting material of the bridge support during the erection of the bridge, so normative level and standard are hardly reached, leaving potential safety hazards to post-operation of the bridge. The invention embeds in advance a plurality of leveling bolts in a pad stone to rotatably level the bolts so that the height of the topmark thereof is consistent in scale height of bottom surface of a lower filler plate of the support; the support is suspended on the leveling bolts and is regulated to be consistent with the axial line of the pad stone; a bonding material is poured between the pad stone and the support. The invention can, without being impacted by inconsistent compression of the dry hard mortar, level the support via the leveling bolts at one time, thus avoiding the defect of current method that repeated loading/unloading and leveling are required.
Description
Technical field
The present invention relates to the leveling method that a kind of large-scale bridge support is installed, but specifically be the method that a kind of large-scale bridge support is installed one-time leveling, belong to the highway engineering construction technical field.
Background technology
Bridge pad is an important component part of beam bridge girder construction, is the load transfer device that is provided with in the supporting place of bridge span structure and bridge pier or abutment.Along with the development of highway construction, bridge beam body and bridge pad are increasing, and supporting capacity and the deformability to bridge pad also constantly proposed new requirement simultaneously, and its construction and installation technical requirements is more and more higher.Because bridge pad is bigger, pier stud top operational space is limited, and bearing leveling when construction is difficult to reach requirement.Bridge erection at present adopts dry mortar as the bridge pad levelling grouting agent that casts anchor, so bearing also just is difficult to reach the standard level standard, stays serious potential safety hazard for the operation of bridge later stage.
Summary of the invention
But the objective of the invention is to disclose the method that a kind of large-scale bridge support is installed one-time leveling, to overcome existing in prior technology deficiency and defective.
The technical solution adopted in the present invention is:
A. pre-buried four leveling bolts in pinner;
B. rotating the leveling bolt makes its top mark high consistent with bearing lower bolster bottom surface absolute altitude;
C. bearing is hung on pre-buried good leveling bolt, it is consistent with the pinner axis to adjust bearing;
D. infusion and binding material between pinner and bearing.
Beneficial effect of the present invention: since in the pinner concrete pre-buried leveling bolt, be not subjected to inconsistent influence of stiff mortar decrement, can make the bearing one-time leveling, avoided existing property method to need repeatedly to load and unload repeatedly the defective of levelling by the leveling bolt, improve construction quality, saved cost.
Description of drawings
Accompanying drawing is installed status architecture generalized section after the leveling for the present invention.
Reference numeral is: bearing 1, leveling bolt 2, pinner 3, bearing crab-bolt preformed hole 4, bearing lower bolster 5.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is done and to describe in further detail:
A. select four leveling bolts (2) according to the size of bearing (1), with the whole screw mandrel of leveling bolt (2) nut of all screwing on, determined the physical dimension of bearing lower bolster (5), build the preceding bearing crab-bolt preformed hole (4) of reserving of pinner (3), four leveling bolts (2) that will have nut are embedded in the pinner (3), make the nut of leveling bolt (2) exceed pinner (3) end face, the pre-buried position of leveling bolt (2) guarantees at bearing lower bolster (5) in length and breadth in scope;
B. reach 20Mpa when above at pinner (3) concrete strength, at first rotate pre-buried four leveling bolts (2), make its top mark high consistent with bearing lower bolster (5) bottom surface absolute altitude;
C. bearing (1) is hung on pre-buried good leveling bolt (2), it is consistent with pinner (3) axis to adjust bearing (1);
D. between pinner (3) and bearing (1), pour into the gravity gravity flowing levelling mortar.
Claims (2)
