Embodiment Construction

[0006] Assemble the bridge deck structure on the tire frame 4 on the side of the designed installation position of the bridge deck structure. All on the same straight line and loosen the anchorage of each through-type jack 5, pass the steel strand 6 through each through-type jack 5, and one end of the steel strand 6 is fixed on the end column 3 fixedly connected with the tire frame 4 At the top, after the steel strands 6 are arranged into a straight line, the other end is clamped by the anchorage of the through-hole jack 5 on the top of the head column 1, and then the cable wind rope 8 is fixedly connected to the top of the head column 1. The other end is connected in series with the turnbuckle 7 and anchored to the ground; after checking and confirming that the anchorage of the through-type jack 5 on each middle column 2 is in a loose state, adjust the plunger of the through-type jack 5 on the head column 1 to extend out The length is to apply a preload to the steel strand 6,...

Abstract

The invention relates to a stress self-balancing and deviation-rectifying equipment for upright post system in bridge deck structure jacking construction. Said equipment includes the following components: straight-through type jack, stranded wire, wind-resisting guy rope and anchorage device, etc. Said invention also provides the concrete mounting method and steps of the above-mentioned all the components for implementing stress felf-balancing and deviation-rectifying method of upright post system in bridge deck structure jacking construction.

Description

technical field [0001] The invention relates to a force self-balancing and deviation correcting device for a column system in the pushing construction of a bridge deck structure. Background technique [0002] At present, the jacking construction technology is often used in bridge construction, that is, the bridge deck structure is first assembled on the tire frame at the side of the bridge deck structure design installation position, and then the assembled bridge deck structure is pushed and slipped along the top of each column. Install it at the designed location. When the bridge deck structure touches the top of the column during the pushing process, a horizontal thrust will be generated on the column due to friction, resulting in displacement of the top of the column. If the horizontal thrust exceeds the design standard of the column, the column will be damaged, which will affect the safety of the bridge and construction. pose a danger. In the existing construction tech...
