Therefore, the best way to ship it is to use a module transport vehicle to ship it; because a single structural module is narrow in width, low in height, and light in weight, if it is transported and shipped according to the traditional process of transporting individual modules one by one, not only Repeated transportation of module transport vehicles is required, which leads to a waste of transportation resources, and at the same time occupies more construction sites, increasing the time of transportation and shipping and the cost of transportation

Embodiment Construction
[0026] Such as figure 1 — image 3 Shown, the present invention adopts following steps:
[0027] Step 1: Prefabricate several transport beams 1, superimposed and fixed structures 2 and supporting pier 3 in advance according to the needs; wherein, the transport beam 1 includes: the beam body 11, which is an I-beam; it is installed on the On the top of the two ends of the beam body 11, the lateral limit beams (12, 12') used to limit the lateral movement of the module, and several ribs 13 installed inside the beam body 11 by welding;
[0028] The second step: if Figure 4 As shown, first place the supporting pier 3 next to the structural modules that need to be stacked with a forklift, and hoist the transport beam 1 to the top of the supporting pier 3 with a crane;
[0029] Step 3: If Figure 5 As shown, the bottom module 4 is hoisted to the top of the transport beam 1, and fixed by welding;
[0030] Step 4: If Image 6 As shown, the middle module 5 is hoisted to the top of...

The invention relates to an overlaying, fixing and transporting process for elongate structure modules. The overlaying, fixing and transporting process includes the steps: (1), prefabricating a plurality of transporting cross beams, overlaying and fixing structures and cup supports in advance; (2), placing the cup supports beside to-be-overlaid structure modules, and using a crane to lift the transporting cross beams to the top of the cup supports; (3), lifting and fixing bottom modules onto the top of the transporting cross beams; (4), lifting and fixing middle modules onto the top of the bottom modules; (5), lifting and fixing top modules onto the top of the middle modules; and (6), transporting entire overlaid modules onto ships or other specified places. Field space resources are utilized to the utmost extent, transporting and shipping time of module transporting vehicles are shortened, and cost for field building and transportation cost of the module transporting vehicles are saved.
Description
technical field [0001] The invention relates to a module fixing and transportation process, in particular to a stacking and fixing and transportation process suitable for marine engineering and land terminal slender structure modules. It belongs to the field of offshore oil engineering. Background technique [0002] For offshore oil platforms and similar large-scale steel structure modules, there are usually three ways to transport and ship them: one is to build sliding shoes at the bottom of the module, and then the entire module is loaded on the slide as a whole; the other is The module is hoisted onto the ship as a whole by a floating crane; the third is to use the module transport vehicle to transport and load the module as a whole. In offshore oil platforms and similar large-scale steel structure modules, there are often some slender modules, which are characterized by narrow and long structures. Due to its special structural form, the overall flexibility of the struc...
