The gabion block 10 can be slidably arranged on the parallel slide rails 40 of the hull deck, and is used to carry the cylindrical gabion 50; the gabion block 10 includes: a plurality of base rods 11 arranged in parallel; a plurality of bearing rods 12 arranged in parallel and fixedly connected above the base rods 11. The base rods 11 are perpendicular to the bearing rods 12; the base rods 11 are perpendicular to the slide rails 40; at least one of the two ends of the base rods 11 is provided with baffles extending downward, and the inner wall of the baffle is arranged adjacent to the slide rail 40, and the two baffles can limit the gabion block 10 to slide above the parallel slide rails 40, so as not to derail due to lateral movement.

[0036] At least one end of at least one of the base rods 11 is also provided with a safety plate. The safety plate and the baffle 15 can be the same plate body or different plate bodies, and the present application does not limit this. In this embodiment, the safety plate and the baffle 15 are of the same structure. Further, in order to ensure stable positioning and avoid positioning failure, both ends of the base rod 11 are provided with safety plates 15. Of course, in the case of multiple safety plates 15, only one of the safety plate positioning holes needs to be aligned to facilitate positioning by construction personnel.

[0037] The safety plate 15 is provided with a first positioning hole, and the far end of the slide rail 40 is provided with a second positioning hole. When the first positioning hole and the second positioning hole are aligned, the gabion pulley 10 is positioned by penetrating and connecting through the pin shaft 13. The base rod 11 and the bearing rod 12 are both I-beams. A limit rod 17 perpendicular to the bearing rod 12 is also welded to the bearing rod 12. Preferably, a plurality of limit rods 17 are also provided on the bearing rod 12; the limit rod 17 is perpendicular to the bearing rod 12, and the plurality of limit rods are arranged along the length direction of the base rod 11, and the space between two adjacent limit rods is used to support the gabion 50.

[0038] like Figure 1 As shown, the gabion pulley 10 can carry two gabions 50 at one time, and the two gabions 50 are limited by four limiting rods 17, and the throwing efficiency of the gabions 50 can be improved. The length of the base rod 11 is greater than the length of the cylindrical gabion 50.

[0039] In other feasible embodiments, in order to facilitate on-site construction, the bearing rod 12 is further provided with limiting square timbers perpendicular thereto.

[0040] like Figure 4 , Figure 5 , Figure 6 As shown, a new type of gabion 50 is also provided in the embodiment of the present application to facilitate manufacturing, on-site filling of stones and hoisting. The gabion 50 is used to block the blade of the steel caisson in the air to prevent the stones from rolling into the caisson from the suspended position when throwing stones. The caisson is a steel caisson, which is a 10,000-ton steel caisson (about 8,000 tons). In order to have a better shielding and hanging effect, the gabion 50 is a cylindrical structure with a diameter of about 2.2m and a length of about 2.78m. The weight of the gabion 50 filled with stones is more than 10t, roughly about 18t.

[0041] Specifically, the new gabion 50 includes: a cylindrical main body 60; a mesh cover fixedly welded to both ends of the cylindrical main body 60. The cylindrical main body 60 is provided with a plurality of lifting ears 59. The cylindrical main body 60 includes a plurality of longitudinal steel bars 52 arranged in parallel along the circumferential direction, and a plurality of circular ring frames 51 arranged at intervals along the longitudinal direction; a plurality of longitudinal steel bars 52 are fixedly welded to the plurality of circular ring frames 51; wherein two of the circular ring frames 51 are respectively welded to both ends of the cylindrical main body 60. The mesh cover includes a plurality of end steel bars welded vertically; the mesh cover is fixedly welded to the circular ring frames 51. The end steel bars are a plurality of perpendicular warp and weft steel bars.

[0042] 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. The plurality of inner longitudinal steel bars 52a are welded to the inner ring wall 51a of the circular frame 51. The plurality of outer longitudinal steel bars 52b are distributed on both sides of the circumference of the plurality of inner longitudinal steel bars 52a. The number of the outer longitudinal steel bars 52b is greater than the number of the inner longitudinal steel bars 52a. The plurality of outer longitudinal steel bars 52b are welded after filling with stones. 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.

[0043] 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 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.

[0044] The embodiment of the present application also provides a gabion laying vessel, which can be transformed by an anchor boat without the need for separate manufacturing. The anchor boat only needs to cut off the front roller, and the gabion pulley 10 can be installed on site.

[0045] Specifically, the gabion laying vessel comprises: a hull, on which a parallel slide rail 40 is fixedly arranged; a gabion pulley 10 slidably arranged on the parallel slide rail 40 of the hull deck, which can adopt any of the gabion pulleys described in the above embodiments.

[0046] The two ends of the parallel rails 40 are also provided with blocking plates 18 perpendicular thereto; the blocking plates can be welded to the hull deck or to one end of the parallel rails 40, which are higher than the parallel rails 40. The blocking plates 18 are parallel to the base rods 11. The gabion block 10 is restricted to slide between the two blocking plates 18. The parallel rails 40 are also made of I-beams.

[0047] In order to facilitate the subsequent unhooking and recovery of the wire rope, one end of the wire rope provided on the hanger of the gabion throwing ship is connected with a hook assembly 70 to lift the gabion 50. Figure 7 As shown, the hook assembly 70 includes a main body plate 61 and a hook 63 rotatably connected to the main body plate 61. The hook 63 is rotatably connected to the main body plate 61 through a rotating shaft 62; the hook 63 includes a hook body 69 located on one side of the rotating shaft 62 and a counterweight body 68 located on the other side of the rotating shaft 62; the weight of the counterweight body 68 is greater than the weight of the hook body 69. Figure 1 As shown, the hoisting is lowered until the gabion 50 is landed, and then the hook assembly 70 is further slightly lowered. At this time, the counterweight body 68 will descend automatically, and the hook body 69 will be lifted to complete the automatic unhooking. At this time, the wire rope is wound to lift the hook assembly 70 to complete the recovery.
