The steel box structure is manufactured in a sectional matching mode, welding lengthening needs to be conducted in the process of placing the steel box into the groove section, meanwhile, the butt welding time of the steel box is long due to the fact that the weight of the steel box is large, and therefore the whole process of lifting operation of the steel box needs to be conducted on the steel box through the crawler crane in the process of connecting the steel box.

Because bridge construction is often in the geographic position that climatic conditions change very fast, often face weather changes such as wind, raining in steel box hoist and mount operation, and crawler crane hoist and mount are flexible hoist and mount form, consequently need to fix the steel box temporarily when weather is changeable to ensure construction safety.

In the prior art, after the steel box is hoisted and aligned by using the crawler crane, a cable rope is adopted to connect the middle part of the steel box with a ground anchor for temporary pulling and fixing.

Because the cable rope is of a flexible structure and has no rigid supporting effect on the steel box, the method can be used only in breeze or light wind days and has certain limitation.

Because the steel box lacks a better supporting method in the weather with larger wind power, the construction is often stopped from the aspects of construction safety and reliability, so that a certain construction period is wasted for construction operation, and the construction progress is influenced.

In other words, the steel box structure of the continuous wall lacks better supporting equipment and a method in the butt joint process, has poor adaptability to weather changes and has smaller safety redundancy for construction.
