[0068] Optionally, before hoisting the box column 1, it is necessary to detect whether the current floating box area 2 meets the installation conditions for the box column 1. Among them, it is possible to detect whether the weight of the floating box area 2 reaches a preset weight that can prevent strong wind impact or movement. If the weight of the floating box area 2 reaches the preset weight, it is determined that the installation conditions for the box column 1 are met.

The reflective identification plate can be set in the middle of the top, and parameters such as the installation elevation and verticality of the box column 1 are measured through the reflective identification plate.

[0075] Optionally, before hoisting the box column 1, in order to facilitate the adjustment of the box column 1 during installation, a steel wire rope can also be set. The steel wire rope passes through the installation adjustment lifting ear or is bound to the installation adjustment lifting ear. The length of the steel wire rope can be determined according to the installation position of the installation adjustment positioning lifting ear and the position of the connection anchor point at the other end of the steel wire rope. Among them, an adjustment hoist can also be set on the steel wire rope to adjust the length of the steel wire rope by using the adjustment hoist.

[0076] Optionally, before hoisting the box column 1, the measuring instruments and hoisting equipment required for the installation of the box column 1 can also be installed first. Among them, the measuring instruments include measuring devices such as total stations and levels, and the hoisting equipment can include truck cranes, overhead cranes and other equipment.

The magnitudes of the first preset height and the second preset height can be determined according to actual requirements and the length of the box column.

[0080] In one embodiment, two cranes cooperate to turn over the box column 1, that is, the two cranes lift the hooks simultaneously, hoist the box column 1, stop when it is 200 mm above the ground, observe the overall state, and after determining that the states of the box column 1 and the cranes are stable, lift the box column 1 simultaneously, and it can be lifted by 5 m. At this time, the hook of the second crane stops rising, and the main hook of the first crane continues to rise. The main hook rises 5 m relative to the auxiliary hook, and the auxiliary hook slowly lowers at this time (the main hook does not move at this time) until the bottom of the box column 1 is 1 m above the ground, and then the main hook continues to rise until the main hook bears all the force, forming a single crane bearing the force, thus completing the turning-over operation.

[0081] S103: Use the positioning object to lower the box column 1 to the installation position, and adjust the verticality of the box column 1 by adjusting the cable 3 and the installation adjustment positioning lug.

[0082] Optionally, using the positioning object to lower the box column 1 to the floating box area 2 includes: hoisting the box column 1 above the installation position; controlling the box column 1 to approach the positioning object and gradually unload the box column 1.

[0083] In one embodiment, when lifting the box column 1, the direction state of the box column 1 can be adjusted by the steel wire rope connected to the installation and adjustment positioning lifting lug, and the box column 1 is lifted by the first crane to above the installation position in the floating box area 2. After determining that it has reached above the installation position, the box column 1 is gradually lowered by the first crane, so that the side of the box column 1 slowly approaches the clamping code plate and the bottom of the box column 1 falls to the installation position inside the sectional outer frame.

[0084] Optionally, after the box column 1 is closely attached to the clamping code plate, the bottom end of the box column 1 is made to abut against the floating box area 2, so as to reduce the tension on the first crane until the tension it bears is one-third of the weight of the box column 1. And, during the process of placing the box column 1, the box column 1 is kept in place without displacement.

[0085] Optionally, the floating box area 2 is equipped with connecting anchor ears, and the connecting cable is provided with an adjusting hoist. The verticality of the box column 1 is adjusted by the adjusting cable 3 and the installation and adjustment positioning lifting lug, including: connecting one end of the adjusting cable 3 to the connecting anchor ear and the other end to the installation and adjustment lifting lug; after the box column 1 is placed at the installation position, the verticality of the box column 1 is adjusted by using the adjusting hoist.

[0086] Optionally, as Figure 4 、 Figure 5 shown, the adjusting cable 3 can be a steel wire rope. After the box column 1 is placed at the installation position, one end of the steel wire rope is connected to the connecting anchor ear, and the verticality of the box column 1 is adjusted by using the adjusting hoist on the steel wire rope to meet the verticality requirements. Among them, the installation and adjustment positioning lifting lugs on each side of the box column 1 can be connected to a connecting anchor ear through a steel wire rope.

[0087] S104: Weld and fix the box column 1.

[0088] Optionally, welding and fixing the box column 1 includes: welding and fixing the box column 1 by using a preset number of stiffeners; after determining that the accuracy meets the preset conditions, controlling the crane to release the hook and welding the remaining stiffeners; after passing the ship inspection, welding the main welds.

[0089] Optionally, the bottom end of the box column 1 can be provided with welding positions for a plurality of stiffeners, and the box column 1 is fixed on the floating box area 2 by using the welded stiffeners. Among them, these welding positions can be arranged at intervals. When welding and fixing the box column 1 by using a preset number of stiffeners, multiple welding positions can be selected at intervals according to the welding positions, and there can be at least one welding position for the remaining stiffeners to be welded left between the welded stiffeners. During welding, a symmetric welding method can be adopted for welding to reduce problems such as welding deformation and asynchrony. And, during welding, a measuring instrument is used to observe the state (such as verticality) of the box column 1 in real time, and when it is detected that the box column 1 is tilted or shaken, an adjusting hoist and welding stiffeners are used for adjustment to control the installation accuracy.

[0090] Optionally, the size of the preset quantity can be determined according to conditions such as the type of stiffeners, the size, weight, dimensions of the box column 1, and the quantity of welding positions. After welding the preset quantity of stiffeners, the installation accuracy of the box column 1 can be detected using a total station instrument. After determining that the installation accuracy meets the requirements according to the measurement results, it is determined that the preset conditions are satisfied.

[0091] Optionally, after controlling the crane to release the hook, the box column 1 is tightened using the adjusting cable 3. At this time, the adjusting cable 3 serves as a windproof cable to prevent the box column 1 from being affected by strong winds.

[0092] Optionally, after the welding of the stiffeners is completed, the main welds of the box column 1 can be processed first (such as grinding the main welds using a grinding machine), and then the ship inspection is carried out. After passing the ship inspection, the main welds are closed with the outer plate to complete the installation of the box column 1.

[0093] Optionally, the installation of each box column 1 on each floating box area 2 is gradually completed in the above manner. Compared with the existing installation method, the amount of high-altitude work of the operators can be reduced. Through measures such as adjusting the windproof cable and positioning the code plate, the need for high-altitude work can be greatly reduced, thereby reducing the construction intensity of the operators, significantly reducing the safety risks, significantly reducing the construction measure costs, and effectively improving the work efficiency, helping to promote the progress of the project.
