Embodiment 1

[0042] The present invention is based on the construction conditions of a finger-type wharf for an actual project, and carries out a series of studies on refitting the bridge erecting machine to form a complete set of construction methods for the superstructure of the high-pile wharf. Considering comprehensive requirements and construction schedule, special equipment is used for construction. This embodiment mainly elaborates on the design of special equipment, assembly and load test requirements, the process of lifting and installing concrete prefabricated parts, and the key points of mobile and in-place construction technology.

[0043] The front leg of the offshore bridge erecting machine is supported on the top of the front pile, which is the front end support point when erecting the beam. In order to make the front outriggers adapt to the horizontal deviation of the lower steel pipe piles or concrete piles, a transition joint is provided on the front outrigger steel pipe ...

Embodiment 2

[0057] As a preferred embodiment of the present invention, with reference to the attached Figure 1-7 , this embodiment discloses a bridge-erecting machine at sea, comprising a main girder, a front leg, a middle leg and a rear leg; the front leg of the bridge-erecting machine is connected to the main beam of the bridge-erecting machine The lower chord is locked, and the front outrigger transverse travel mechanism is installed at the lower part of the front outrigger; the upright column of the front outrigger is set as an inner and outer joint structure, and is equipped with a hydraulic jack for adjusting the height of the front outrigger; the front outrigger transverse travel mechanism The bottom of the track beam is connected by bolts to a number of transition sections that are sleeved on the top of the pile, and the distance between the transition sections at the bottom of the track beam of the front outrigger lateral travel mechanism is set according to the distance between ...

Embodiment 3

[0063] As another preferred embodiment of the present invention, with reference to the attached Figure 1-7 , this example discloses:

[0064] A construction method of an offshore bridge erecting machine is characterized in that it comprises the following steps:

[0065] Step A, the assembly step of the bridge erecting machine, assemble the bridge erecting machine according to the installation and operation specifications of the bridge erecting machine; when assembling the bridge erecting machine, lock the front leg of the bridge erecting machine with the lower string of the main girder of the bridge erecting machine through the double-ended studs , the front outrigger transverse walking mechanism is installed at the lower part of the front outrigger; the upright of the front outrigger is set as an inner and outer joint structure, and a hydraulic jack is configured to adjust the height of the front outrigger;

[0066] At the bottom of the track beam of the front outrigger tra...

Abstract

The invention discloses an offshore bridge erecting machine and a construction method thereof, and relates to the technical field of offshore platform construction. The construction method of the offshore bridge erecting machine of the present invention comprises the bridge erecting machine assembling step, the bridge erecting machine test step, the bridge erecting machine in place step, the prefabricated part installation step and the bridge erecting machine moving step, the construction method of the offshore bridge erecting machine of the present invention , is to improve on the basis of the bridge erecting machine used for roads and railways, transform its front outrigger structure to adapt to different steel pipe pile spacing and load requirements, and at the same time set transition joints on the front outrigger steel pipe piles, with The function of front, back, left, and right adjustments is to adapt to the horizontal construction deviation of the steel pipe piles or concrete piles at the lower part; the structure of the middle outriggers is transformed so that it can adapt to the complex characteristics of the steel bars on the pier caps on the top of the steel pipe piles, and finally realize the transformation of water operations into Construction on the road reduces the impact of unfavorable factors such as swells and tides, and at the same time speeds up the construction progress, improves the installation quality, and reduces construction costs.

Description

technical field [0001] The invention relates to the technical field of offshore construction, and more specifically relates to an offshore bridge erecting machine and a construction method thereof. Background technique [0002] Offshore platforms are generally high-piled wharfs such as wharf platforms and ship lift platforms, and are generally located in relatively deep sea areas, and sea conditions are often affected by factors such as tides and sea winds. [0003] The lower structure of the high-piled wharf includes underwater structures such as steel pipe piles and concrete piles, and the upper part is mostly a prefabricated concrete beam-slab structure. For a long time, the installation of prefabricated components on the upper part of high-pile beam-slab wharf has basically relied on large crane ships and barges. The construction process of using traditional crane ships and barges to install prefabricated components is greatly affected by factors such as swells and tide...
