Using a box unit with a fluid pipe arranged in it, air is sent into the box to float it on water, and it is towed to the required location.
At that location, the air is removed from the box units, the boxes are allowed to settle, and the boxes are filled with stuffing to form a marine structure.

Traditionally, in the construction of seawalls, artificial islands, and embankments, a concrete box built on land was floated on the water, towed to a predetermined location, and then submerged.
A construction method has been proposed in which filling material such as sandstone is placed inside the box and fixed by gravity.

あつた。つまり、吃水量が調節できないという問
題点である。 Furthermore, if such a box is used, much work remains to be done on the superstructure, and it will take a considerable amount of time to complete. Furthermore, when constructing a structure at great depth, a large box is required, but this increases the amount of water that can be absorbed, making it approximately half the size of a box, and is also constrained by the water depth of the dock. However, those designed for deep water use not only were not structurally possible, but also had problems such as limitations due to the depth of the channel for towing. In other words, the problem is that the amount of water intake cannot be adjusted.

ある。 An object of the present invention is to enable safe and efficient towing of a box that constitutes the frame of a marine structure. A further object of the present invention is to prevent the box from moving under the influence of tidal currents and waves after the box has been seated and before filling is introduced. The purpose of this is to enable the towing of large boxes suitable for constructing structures at great depths.

As a means to solve this problem, the present invention combines a plurality of boxes surrounded by side walls on all sides, closed at the top with a top plate, and opened at the bottom at the sides, and has a tip attached to each of the boxes. A box unit consisting of a fluid pipe with branch communication and an on-off valve at the base end is floated in water with the bottom facing down, and air is fed into the box from the fluid pipe to form the box. After adjusting the amount of water intake, this box unit is towed to a predetermined location, and at that location, the air inside the box is removed through the fluid pipe, the entire box is allowed to settle, and its bottom edge is placed on the water bottom. This is a method of constructing a marine structure, which is characterized in that a filling material is then inserted into the box to stabilize it.

In the invention of the method, since a box unit including a plurality of boxes is towed and sunk, the construction efficiency of marine structures is higher than when each box is towed and sunk individually. Floating on water with the bottom of the body facing down, the air inside each box is fed through fluid pipes, and the internal air pressure is adjusted to adjust the amount of water taken up by the box unit. Stability during towing is improved, and a deep-water box unit can be towed even in shallow water. Further, since the box units are allowed to settle by removing air from each box via the fluid pipe, the box units are quickly set down, and as a result, the influence of water currents and waves is small.

Each box 2 has an outer wall having an arcuate cross section. Due to this shape, the bending moment exerted on the outer wall due to earth pressure, etc., was reduced to one-tenth that of a case where the outer wall was simply flat. Therefore, the overall weight was also significantly reduced. Moreover, the top of the top plate 9 becomes a deck, and constitutes the so-called superstructure itself, which serves as a roof when towed or when the ship is submerged and fixed. A fluid pipe 4 is attached to the top plate 9. The above-mentioned main valve 10 and branch valve 11 are attached to the fluid pipe 4, and the entire pipe assembly can be removed from the top plate 9. 12 in the diagram
