Caisson foundation has the characteristics of high bearing capacity, high rigidity, good stability, strong earthquake resistance, no maintenance and protection, and reliable construction. It can sink to a deep ideal base or directly sit on the base bed (setting the foundation) to obtain the required bearing capacity. Therefore, it is increasingly used in the deep-water foundation of long-span bridges.

The mesh cover includes a plurality of vertically welded end steel bars; the mesh cover is fixedly welded to the circular ring skeleton 51. The end steel bars are a plurality of perpendicular warp and weft steel bars.

[0033] The plurality of longitudinal steel bars include a plurality of inner longitudinal steel bars 52a and a plurality of outer longitudinal steel bars 52b. The plurality of outer longitudinal steel bars 52b are welded to the outer ring wall 51b of the circular frame 51 and are arranged near the area near the lifting lug 59.

Without welding the outer longitudinal steel bars 52b, the area near the lifting lug 59 constitutes a stone release opening. After the stones are placed in the gabion 50, the remaining number of longitudinal steel bars are welded to the outer ring wall 51b of the circular frame 51, and the stone release opening is blocked to form a complete gabion 50. The large-tonnage gabion 50 with such a structure can be easily transported and can be filled with stones in the designated construction area of ​​the caisson 500.

[0034] In order to have better structural strength, the gabion 50 also includes a supporting I-beam 58 parallel to the longitudinal steel bars and a plurality of channel steels 55 arranged at intervals along the circumferential direction. The supporting I-beam 58 and the plurality of channel steels 55 are welded inside the circular frame 51. The supporting I-beam 58 is provided with two symmetrically arranged lifting ears 59. The circumferential spacing between two adjacent longitudinal steel bars 52 is between 50 mm and 150 mm.

The number of the circular frame 51 is 4; a single supporting I-beam 58 and three channel steels 55 are evenly distributed along the circumferential direction. The plurality of outer longitudinal steel bars 52b are symmetrically distributed on both sides of the supporting I-beam 58 in the circumferential direction. The inner diameter of the circular frame 51 is between 1 m and 3 m, and the length of the gabion 50 is between 2 m and 5 m. The steel plate thickness of the lifting ears 59 is above 15 mm.

[0035] Specifically, the caisson 500 can be a steel caisson, which is a 10,000-ton steel caisson (about 8,000 tons). In order to have a better shielding effect, the gabion 50 is a cylindrical structure with a diameter of about 2.2 meters and a length of about 2.78 meters. The weight of the gabion 50 filled with stones is more than 10 tons, about 18 tons. The new gabion 50 of this embodiment can be used to close the caisson and prevent the stones from rolling into the caisson from the suspended area when throwing stones.
