Conventional tetra-port that is formed by injecting concrete into the formwork has difficulty in transportation and construction, and cannot be enlarged. These small sofa blocks are light and shaken by waves, which shortens the life due to accidents such as breakage collapse. There was a great deal of damage to the surrounding area, but the conventional technology did not overcome the difficulties and struggled with his countermeasures.

The present invention constitutes a safe and efficient method for forming various marine structures or large tetra pots, which are not pushed by the waves, in the sea or in the water at sea, and immediately constructing them on the fly. It is technical problem to do

A. Configuration

In constructing the present invention, a representative tetrapot was selected among the sofa blocks, and the molding place was formed by arranging a work line having a walking function on the site selected as the construction site, and injecting concrete into the woven fabric on the line. As soon as it was completed, it opened a downward door door and drove it as it was, so it constructed a method of constructing a sofa (으므로 波提).

First, the tetrapot to be installed by the method of the present invention is constructed, but the outer shell of the known tetrapot (1) is made of 5 degrees with a strong chemical fiber, so as to cut at the starting point of the horizontal three-way turning and the vertical turning.

Insert into the inlet (6) and pull it out to the bottom and connect them with c In the horizontal stone angle, the bottom was wrapped with a band (12) connected with a hook made of synthetic resin (11) (11 '), and only the edge (11) (11') was attached to the left and right sides of the stone in the form of a pot handle.

After completion, it is easy to move and prepare a forming baggage device on the work line, that is, by drilling a rectangular sewer on the deck of the hull (13) (14) and closing the opening door (15) (15 ') with hinges on both sides. The winch (16) (17) opens and closes the door (15) and the winch (18) (19) opens and closes with wire ropes (20). (15) In the ceiling frame (21), the outer shell of tetrapot (1), which has not yet been infused with concrete, is placed in the center of the upper surface of (15 ') as shown in FIG. On the bottom of the ropes (24) (25) (26) bound in a triangular phase to the hoisting lifting frame (23) suspended by a winch (22) (27) (28) ( 29), and they spring on the lower part of the left and right clamps 30) Always hold it tightly and open it with solenoid (31) when releasing all of them. Thus, the tetraports are hanged on the hooks (11) (11 ') of horizontal frame angles as shown in FIG. And firmly insert the tip of the concrete pumping hose (32) into the inlet (6) so that the concrete is inflated.In this way, if the shell of the tetrapot has been expanded, remove the concrete pumping hose and place it (9). Pull the c-shaped binding section at the front end of (10) and let the non-return tank (8) come out of the outer surface.The inlet (6) closes the tongue piece (7) and the winch (16) (17) ( 18) Pressing the wire ropes (20) with (19) will open and close the door opening (15) (15 ′) as shown in the phantom line of FIG. 1. Give me te The traport is dropped as shown by the phantom line. After checking that the position is in a stable position in the desired position, open the left and right brackets of the coupling with the solenoid (31) and the lifting rope (23).
