Embodiment 1

[0016] Embodiment one: a kind of walking type pushing device, such as Figure 1-1 to Figure 1-4 As shown, the walking pusher includes five parts: a slide box 1, a slideway 2, a translation jack 3, a lifting jack 4, and a deviation correction jack assembly 5.

[0017] Described slide box 1 is a quadrilateral carrier, is made up of 4 identical slide box main units 11 and 2 transverse slide box main body connectors 121 that connect slide box main unit 11 that are positioned at frame 4 corners (referring to Figure 2-1 to Figure 2-4 ); Described each slide box main body unit 11 comprises slide box main body steel structure 111, stainless steel plate 112, push away ear 113 and translation guide plate 114, the slide box main body steel structure 111 of slide box main body unit 11 is made of 4 hollow A hollow steel frame assembled by the frame includes a load-bearing part 111a composed of a right-angled trapezoidal cross-section and a rectangular hollow frame with a cross-section, and...

Embodiment 2

[0025] Embodiment two: a kind of method for bridge jacking construction---install the walking type jacking method of bridge girder section, it is to utilize the walking type jacking device described in embodiment one of the present invention, to bridge girder section (this implementation For example, a steel box girder) is assembled in sections and pushed into place as a whole, which includes the following steps (see Figure 9-1 to Figure 9-5 ): A, install pusher VI (referring to Figure 9-1 ): Assemble the jacking device VI and pad beam I on the jacking device installation platform VII of the bridge pier; B, jacking the steel box girder II (see Figure 9-2 ): The jacking jack IV extends the cylinder to the set stroke through the control system, and lifts the entire pushing device and the steel box girder II, leaving a certain distance away from the pad beam I; C. The steel box girder II is pushed forward (see Figure 9-3 ); Synchronously control the extension cylinder of the...

Abstract

The invention provides a walking type incremental launching device. The device comprises a slide box, a slideway, a translation jack, a jacking jack and a deviation-rectifying jack assembly, wherein the slide box comprises slide box body units and slide box body connectors connecting the slide box body units; the slide box body units are movably connected by bolts; the slide box body units and the slide box body connectors are movably connected by bolts; the slide box body connectors are movably connected by bolts; the slideway comprises slideway body units and slideway body connectors; the slideway body units are movably connected by bolts; the slideway body units and the slideway body connectors are movably connected by bolts; the slideway body connectors are movably connected by bolts; the whole slide box is put on the slideway and is of an up-down structure; the jacking jack is installed in a jacking jack installation barrel on the slideway; the translation jack is installed on a translation jack installation plate on the slideway; and the deviation-rectifying jack assembly is installed on a deviation-rectifying jack installation rack on the slideway. Used in a method for bridge incremental launching construction, the device has the characteristics of strong generality, convenience in construction and low cost.

Description

technical field [0001] The invention relates to bridge construction equipment and a bridge construction method thereof, in particular to a bridge main girder construction jacking device and a bridge jacking construction method thereof. Background technique [0002] Due to its light structure and high strength, steel box girders are widely used in the construction of long-span bridges at home and abroad. The existing construction methods generally use continuous jacking or towing. The jacking traction system belongs to the ZL series automatic continuous jacking For the push system, the steel box girder or concrete girder needs to be temporarily reinforced with external cables during construction by continuous pushing or towing, and the external cables need to be removed after the bridge is completed. The construction process is cumbersome and the cost of bridge construction increases; The corbel produces stress concentration on the girder, and the girder needs to be strengthe...
