Problems solved by technology

[0004] The purpose of the present invention is to overcome the method of building an artificial island by riprap slopes and cofferdams in the prior art, which has complex procedures, more noise, greater impact on the environment, difficult construction, and often brings greater impact on navigation. Insufficient influence, and aiming at the above-mentioned shortcomings that the method of deep-inserting large-diameter steel cylinders to build islands is mainly suitable for soft soil geological conditions, a method for constructing artificial island segments, assembled artificial islands and assembled artificial islands is provided. It also provides a sea channel

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...

Abstract

The invention discloses an artificial island segment, an assembled artificial island and a construction method thereof. The artificial island segment comprises a main body of a prefabricated part; andan inner cavity is formed in the main body. The assembled artificial island comprises at least two artificial island segments; and the two adjacent artificial island segments are connected with eachother. The artificial island segment comprises the main body of the prefabricated part and the inner cavity in the main body, and the assembled artificial island comprises the prefabricated part of each artificial island segment, so that the segmented prefabrication can be performed beforehand, and then, the artificial island segments are carried to a position to be installed for assembly; and compared with a traditional island construction mode through slope formation by stone throwing, island construction by cofferdams and deep insertion of large-diameter steel cylinders, the water operationand the waterbed foundation excavation quantity are reduced, a deep foundation pit is canceled, the foundation treatment workload is reduced, the environment influence is reduced, the construction difficulty is reduced, the construction time is shortened, the influence on navigation is lower, the cost is lower, the working conditions of various different foundation soil textures can be met, and the adaptability is high.

Description

technical field [0001] The invention relates to the technical field of artificial islands, in particular to an artificial island segment, an assembled artificial island and a construction method thereof, and a sea passage. Background technique [0002] Artificial islands are widely used in the fields of land reclamation, oil drilling, and transportation technology. The existing artificial islands are generally constructed by rappelling slopes to form artificial islands, or building artificial islands by means of cofferdams, or by deep A large-diameter steel cylinder has been inserted to form an artificial island with a flat bottom. [0003] Among them, the method of building slopes and cofferdams by riprap requires the treatment of the underwater foundation to be relatively flat, and the treatment method is also relatively complicated, which generates a lot of noise, has a large environmental impact, and has a relatively complicated process and a relatively long construction...
