[0028] ReferenceFigures 1-5 The embodiment provides a steel caisson offshore floating push-pull frame structure, which comprises a caisson steel shell 1, the caisson steel shell 1 comprises two layers of push-pull frames, and the push-pull frames serve as important auxiliary equipment in the floating process of the steel caisson and play a crucial role. Through the design and use of the push-pull frames, the stability, safety, construction efficiency and cost reduction of the steel caisson in the floating process are improved. The push-pull frames provide necessary support for the caisson steel shell 1, ensure the stability of the caisson in the construction process, and prevent the caisson from tilting or deforming in the floating and sinking process.

[0029] As Figure 3 The two layers of push-pull frames are divided into a bottom layer of push-pull frames 2 and a top layer of push-pull frames 3, the bottom layer of push-pull frames 2 is used for caisson steel shell 1 launching and floating, and the top layer of push-pull frames 3 is used for cable passing and positioning sinking. The bottom layer of push-pull frames 2 comprises first push-pull frames 4 and second push-pull frames 5, the top layer of push-pull frames 3 comprises second push-pull frames 5, the total number of the first push-pull frames 4 and the second push-pull frames 5 in the bottom layer of push-pull frames 2 is 10, which is divided into 4 first push-pull frames 4 and 6 second push-pull frames 5, and the top layer of push-pull frames 3 is provided with 4 second push-pull frames 5.

[0030] The bottom layer of push-pull frames 2 is distributed on the side of the caisson steel shell 1. The bottom layer of push-pull frames 2 located on the long side of the caisson steel shell 1 comprises first push-pull frames 4 and second push-pull frames 5, and the bottom layer of push-pull frames 2 located on the short side of the caisson steel shell 1 comprises second push-pull frames 5.

[0031] Two groups of bottom layer of push-pull frames 2 are arranged along the long side of the caisson steel shell 1, the second push-pull frames 5 and the first push-pull frames 4 in each group of bottom layer of push-pull frames 2 are arranged coaxially, the long side of the caisson steel shell 1 comprises a plurality of tie columns, and the bottom layer of push-pull frames 2 on the long side is coaxially arranged with one of the tie columns. Such an arrangement can ensure that the force transmission is along the direction of the long side of the caisson steel shell 1 during the pushing process, reduce eccentric force, and avoid structural deformation or damage caused by uneven force.

[0032] The second push-pull frames 5 in the bottom layer of push-pull frames 2 on the short side are located at the center position of the short side of the caisson steel shell 1. Such an arrangement helps the bottom layer of structure to uniformly support the caisson steel shell 1 during the pushing process, reducing instability caused by force point deviation.

A second jacking frame 5 is arranged at the center of the short side of the caisson steel shell 1. Such arrangement helps the top layer structure to work together with the bottom layer structure during jacking, to support the caisson steel shell 1 together, to ensure the concentration of stress points, and to improve the stability of the caisson.

[0034] A plurality of top layer jacking frames 3 are arranged at intervals on the long side or the short side of the caisson steel shell 1, and a plurality of bracing columns are arranged on the long side and the short side of the caisson steel shell 1, and the second jacking frame 5 of the top layer jacking frame 3 is coaxially arranged with one of the bracing columns.

[0036] The total height of the second jacking frame 5 is greater than the total height of the first jacking frame 4, and the width of the second jacking frame 5 is consistent with the width of the first jacking frame 4. The first jacking frame 4 is welded by using I-beams of model G40a and model G14, the total height of the first jacking frame 4 is 1.6m, the width is 5.2m, the center of the first jacking frame 4 is located at a position with a height h=6.45m upward from the caisson blade foot 14, and the center of the first jacking frame 4 is located at a position with a height H=1.5m from the water surface (as Figure 3 ). The first jacking frame 4 is arranged on the side of the caisson steel shell 1 along the floating direction, i.e. on the long side of the caisson steel shell 1, which is beneficial to provide stable support and force transmission during floating and sinking. The second jacking frame 5 is welded by using I-beams of model G40a and model G14, the total height of the second jacking frame 5 is 1.7m, the width is 5.2m, and the second jacking frame 5 is arranged in two layers (as Figure 5 ).
