Description
Technical field
The invention belongs to the construction engineering technical field of bridge, particularly relate to a kind of in rotator construction to turn spike with
The equipment that between slipping, space is filled with, is specifically related to use the bridge horizontal of a kind of support means for bridge horizontal construction
Construction of Supporting method.
Background technology
At present in bridge horizontal rotator construction, when using centre bearing swing system, often support is set under top rotary table
Foot, divides into steel limp at spike.When spike is bridge rotating, supporting construction swivel structure insures lower limb smoothly, is symmetrically distributed in vertical
The both sides of axis.It is provided with slideway in the lower section of spike, insures spike when turning and can slide in slideway, to keep swivel structure to put down
Surely.During Superstructure Construction, for keeping Stability Analysis of Structures, the space between spike and slideway need to be tamped, existing general doing
Method is to fill steel, the tetrafluoro combined liner plate being made up of steel plate and tetrafluoro plate.Treat that Superstructure Construction is complete, take out before bridge rotating
Aforesaid steel and the combined liner plate of tetrafluoro, and corrosion resistant plate of mating formation in chute surface.But, in practice of construction, due to bridge
Superstructure load is very big, and the action time constructed is the longest, causes causing the combined liner plate of above-mentioned steel and tetrafluoro growing
Occur to deform significantly under phase, big pressure environment, therefore and be difficult to pull out, affect follow-up operation of turning, from forming
For affecting the bottleneck problem of rotator construction later stage progress, new constructing device and technique certainly will be taked difficult to solve this engineering
Topic.

Use the bridge horizontal Construction of Supporting method of a kind of base support means for bridge horizontal construction of the present invention,
Carry out as follows:
Step 1: lay the steel plate slideway 8 of annular on the end face of concrete lower rotary table.The center of circle of described steel plate slideway and bridge pier yet to be built
Center coincide.Steel plate slideway is installed emery disc 3.Each emery disc 3 center need to be mutually overlapping with the center of spike 1 to be positioned
Close.
Step 2: have emery disc side openings 4 on the sidewall of each emery disc 3, and be furnished with side openings plate 7.
Step 3: will pour in emery disc 3 in dry sand in emery disc 5, with trowel dry sand in emery disc 5 is made real, floating, formed
Sand bedding course.Guaranteeing that this sand bedding course is smooth and level, the end face of sand bedding course is less than emery disc 3 height.
Step 4: be provided with the spike 1 of spike steel limp 2 bottom the top of the sand bedding course described in step 3 disposes.Subsequently,
In the one layer of cement mortar of surface brush of the sand bedding course not covered by spike steel limp 2, form sand finish layer 6.
Step 5: under the stable support of the spike 1 built in step 4, carry out cushion cap above concrete lower rotary table, bridge pier and
The construction of bridge superstructure.
Step 6: after treating the construction construction of the cushion cap described in step 5, bridge pier and bridge superstructure, by side openings
Plate 7 is removed at emery disc side openings 4, makes dry sand 5 in emery disc flow out from emery disc 3.Subsequently, remove emery disc 3, and clear up
Steel plate slideway 8.
Step 7: load onto steel plate in the bottom surface of spike 1, the fit beneath polyfluortetraethylene plate of steel plate bottom spike 1, and
Butter is spread in the bottom surface of polyfluortetraethylene plate.
Step 8: being driven turntable 12 to rotate by pulling equipment by hauling rope, spike 1 rotates along steel plate slideway 8, it is achieved
The flat turn construction of bridge.After turntable 12 rotate in place, between spike 1 and slideway 8, use drift wedging and fix, clearly
Reason construction area, assembling reinforcement, branching standing template, pour envelope hinge concrete, complete bridge horizontal construction.
Useful technique effect
The simple in construction of the present invention, emery disc are with low cost, and processing technology is simple, can on-the-spot processing and fabricating.Sand bedding course in the present invention is
Being made up of dry sand 5 in the emery disc after screening, beating, in emery disc, dry sand 5 self compacting ability is preferable, and settling amount is minimum, thus
The sand bedding course making the present invention has splendid bulk strength and the ability of the anti-deformation of resistance to compression.The present invention can meet Superstructure Construction
Period spike is supported in the construction requirement on lower rotary table smoothly, thus ensures the needs that overall structure is stable.
