It is still another object of the present invention to provide a fabric foam tube having a PC wire rope network in the mortar layer of the outer tube to improve tensile strength and support of the structure.

Another object of the present invention is to provide a new coastal restoration method that is easy to construct, low construction costs, and shorten the construction period by recycling dredged soil and using a fabric foam.

The above and other objects of the present invention can all be achieved by the present invention described below.

Summary of the Invention

Fabric foam tube structure for coastal restoration public using the dredged soil of the present invention is formed in a cylindrical form so that the dredged soil or sand is injected into the inside and the dredged soil inlet 111 is made of a fabric form formed at regular intervals to inject dredged soil or sand from the outside Tube 101, and formed on the outer side of the inner tube is formed in a cylindrical shape so that the mortar is injected between the inner tube and the outer tube and the mortar inlet 112 is formed of a fabric foam formed at regular intervals to inject the mortar from the outside It is characterized by consisting of an outer tube (102).

The fabric foam tube structure of the present invention is characterized in that the PC wire wire rope network 120 is formed between the inner tube and the outer tube so that the PC wire wire rope network is positioned in the mortar layer after the mortar layer 104 is formed. It is done.

In addition, the fabric foam tube structure of the present invention may inject mortar into the inner tube 101, and inject dredged soil or sand into the outer tube (102).

Hereinafter, with reference to the accompanying drawings will be described in detail the contents of the present invention.
