As a result, the overall bulk capacity of the floating body unit 13 is reduced, which saves space during storage and transportation, which is advantageous in terms of cost.

  Next, referring to (2) of FIG. 7, in use, the opening / closing valve 43 is opened, and a gas having a predetermined pressure is injected into the pipe 42 from the gas filling port 45. The predetermined pressure is set slightly higher than the set value of the safety valve 47. The set value of the safety valve 47 is set to a pressure corresponding to the allowable tensile stress of the film material of the buoyancy body 28a to the buoyancy body 28c.

  The injected gas is filled into the buoyancy body 28a to the buoyancy body 28c through the pipe 42. As a result, the buoyancy body 28a to the buoyancy body 28c swell in a columnar shape and change to a use state in which desired buoyancy is generated in the sea. When the inside of the buoyancy body 28a to the buoyancy body 28c rises close to a predetermined pressure, the safety valve operates as an internal pressure adjusting means, and further pressure rise is suppressed. Therefore, when the on-off valve 43 is closed, the use state in which the buoyancy body 28a to the buoyancy body 28c are inflated with the set internal pressure is maintained.

  Here, although it is a set value of the safety valve 47, if this is set according to the use conditions of the floating pier structure 11, a more efficient floating pier structure 11 is obtained. For example, when the load weight applied when using the floating pier structure 11 is large, the set value may be set to a large value. That is, this means that the internal pressure of the buoyancy body 28a to the buoyancy body 28c including the inside of the pipe 42 is increased. Then, since the film | membrane material which comprises the buoyancy body 28a-the buoyancy body 28c has a stretching property, when an internal pressure becomes large, an internal volume will expand and it will become possible to increase the buoyancy which arises in the floating body unit 13 as a result. Because.

  On the other hand, when the load weight applied when using the floating pier structure 11 is small, the set value may be set to a small value. As a result, the internal pressures of the buoyant bodies 28a to 28c are reduced and the volumes thereof are reduced, and the buoyancy generated in the floating body unit 13 is reduced. In this case, since the tensile stress generated in the film material of the buoyancy body 28a to the buoyancy body 28c is reduced, the service life of the floating body unit 13 is increased.

  In this way, the floating unit 13 in the storage state is filled with gas and sequentially sent to the sea surface, and connected to the subsequent floating unit 13 each time. The floating pier structure 11 having a length of can be easily constructed. Therefore, even when the quay or wharf is damaged by the earthquake, it is possible to extend the floating body unit 13 from the ship side and install the floating pier structure 11 toward the quay or the like.

  FIG. 8 is a side view showing another usage state of the floating pier structure shown in FIG.

  Referring to the figure, a state where the floating pier structure 11 is constructed from the offshore to a shallow such as a coast is shown. In the use state of FIG. 1, since the seabed 19 is deep, it can be used in the state where the floating pier structure 11 as a whole floats. However, in the case of a slope such as a sandy beach where the seabed 19 rises toward the land as shown in FIG. At least a part of the front end side of the floating pier structure 11 is landed.

  In this case, in the floating unit 13a at the tip of the floating pier structure 11 on the land side, the distance between the plate 27a and the seabed 19 is the smallest, and the buoyancy does not work sufficiently, so the weight of the plate 27a. In addition, the load on the buoyancy body 28a-1, the buoyancy body 28a-2, and the buoyancy body 28a-3 are greatly applied. Therefore, the buoyancy body 28a-1, the buoyancy body 28a-2, and the buoyancy body 28a-3 attached to the lower surface of the plate-like body 27a are deformed by receiving a large compressive force in this order. Then, since the internal pressure set at the time of deployment in FIG. 7 increases, the gas corresponding to the increased amount is discharged from the safety valve 47.

  Thereby, each of the buoyancy body 28a-1, the buoyancy body 28a-2, and the buoyancy body 28a-3 is deformed to have a smaller volume in this order as shown in the drawing. As a result, since the buoyancy body 28a-1, the buoyancy body 28a-2, and the buoyancy body 28a-3 are deformed along the inclination of the seabed 19, the upper surface of the plate-like body 27a disposed thereon does not vary greatly.

  Such deformation continues from the buoyancy body 28b-1 to the buoyancy body 28b-2 of the floating body unit 13b, and enters a floating state without landing from the buoyancy body 28b-3 of the floating body unit 13b. In this way, since the floating unit 13a to the floating unit 13d are installed in a stable state with respect to shallow water such as the coast, the floating pier structure 11 can be stably provided regardless of the installation environment such as partial landing. It can be installed. Incidentally, the step can be easily coped with by installing a slope table 20 or the like between the plate-like body 27a on the front end side and the sandy beach.
