Embodiment 1
[0096] Such as Figure 1-3 , shown in 4a-4d, an artificial island segment, including a prefabricated body 1, the body 1 is provided with an inner cavity 11.
[0097] The artificial island segment described in the present invention, through the body 1 including the prefabricated structure, and the inner cavity 11 provided in the body 1, since the body 1 is a prefabricated structure, it can be prefabricated in advance, and then dragged Transported to the location to be installed, in addition, an inner cavity body 11 is set in the body 1, and the buoyancy of the body 1 can be changed through the counterweight in the inner cavity body 11 to facilitate settlement; since the artificial island segment is prefabricated in sections, Then each artificial island segment is also easy to assemble and connect. Compared with the existing artificial islands built by riprap slopes and cofferdams, it reduces the work on the water, reduces the excavation of the underwater foundation, and also ca...
Embodiment 2
[0105] Such as Figure 5a , 5b , 6, and 7, the present invention also provides an assembled artificial island, comprising at least two artificial island segments, and two adjacent artificial island segments are connected to each other.
[0106] The aforementioned two adjacent artificial island segments are connected to each other along the transverse direction or / and longitudinal direction. Two adjacent artificial island segments are connected to each other by a U-shaped waterstop 5 . Two adjacent artificial island segments are connected to each other by a U-shaped baffle 6 , and the baffle 6 forms an end cavity 61 with the two artificial island segments. The end cavity 61 is filled with underwater non-dispersible concrete or waterproof grout.
[0107] Two adjacent artificial island segments are connected to each other through at least one pulling device 9 . Two adjacent artificial island segments are connected to each other through two pulling devices 9, and each pulling ...
Embodiment 3
[0118] As shown in Figures 5-7, 8a, 8b, 9, 10a, 10b, 10c, and 10d, the present invention also provides a method for constructing a prefabricated artificial island. The method for constructing a prefabricated artificial island includes the following steps:
[0119] Step 1. On-site preparation, laying the gravel cushion of the foundation bed underwater in the area where the assembled artificial island is to be installed;
[0120] Step 2, hauling the first artificial island segment, sealing both ends of the first artificial island segment, and hauling it to the location to be installed;
[0121] Step 3: sinking the first artificial island segment and implanting it in the position to be installed;
[0122] Step 4, hauling the second artificial island segment, sealing both ends of the second artificial island segment, and hauling it to the location to be installed;
[0123] Step 5, the second artificial island segment is sunk, and the first artificial island segment and the second...
