More specifically, the present invention relates to a pier and a unit for the pier, which is easy and reliable to assemble, and which can improve the rigidity against bending of the pier as much as an ordinary integrated pier.

方法で連結することにより、台船を組み立てている。[0003] The total weight of an object loaded on a barge, such as a heavy machine such as a crane and a heavy object carried by a crane, usually reaches 100 to 200 tons. In order to obtain a loading capacity that can withstand this total weight, a large flat boat with a size of at least 100 m 2 (for example, a length of 17 m and a width of 9 m) is used. When transporting such a large-sized barge by land, a large-sized trailer having a special carriage must be used, which increases the cost. Further, since it is large in size, it is often difficult or difficult to secure a carry-in path, and there is a problem that it cannot be carried in and out unless there is a large space at the construction site. Therefore, in recent years, a berth in which a plurality of units each made of a hollow block body are combined has been proposed. This unit-type barge is carried by transporting each unit one by one on a trailer when transporting, and when arriving at the construction site, adjacent units are bolted together with plates, connected by welding, wire connection, etc. By assembling, the ship is assembled.

る。However, in the conventional unit type barge, adjacent units are connected to each other by using bolts, welding, wires and the like at places such as bottom and side surfaces of the units. Therefore, there is a problem that the connection work requires work underwater, requires a high degree of skill, takes time, and cannot achieve a good connection state.

部的に変形してしまうという問題もある。Further, since the respective units of the pontoon can rotate in different directions with the connecting portion as a fulcrum, they are weak against bending, particularly bending in the vertical direction. Therefore, if a unit receives a wave or wind, each unit sways up and down and is unstable. Moreover, when a heavy load is placed on the pontoon, stress concentrates on the unit directly below and sinks deeply,
Other units, especially those far from the load, receive little stress and do not sink much. Therefore, there is also a problem that the boat is locally deformed.

じやすいという問題もある。[0006] Further, when a river bank is constructed, conventionally, in order to enhance the stability of the barge when carrying cargo on the bank, the longitudinal direction of the barge is oriented in the width direction of the river. In addition, heavy machinery such as cranes is installed in the stern or on the top of the berth. Therefore, the flow of the river is narrowed by the pontoon, and it is blocked in some cases.Therefore, there is a problem that the flooding of the river or the overturning of the pontoon is likely to occur during flooding during the rainy season. is there.

As the side surface reinforcing member 19, a rod-shaped body made of a steel material or the like having a length of about 0.5 to 1 times the length of each of the two unit main bodies is adopted. In particular, it is preferable to use H-shaped steel as the side surface reinforcing member 19 because it is lightweight and high bending rigidity can be obtained. The side surface reinforcing member 19 is locked to the side surfaces of the two unit bodies by a fixture 20 having a U-shaped cross section. A support member 21 for supporting the side surface reinforcing member 19 from above and below is provided near the boundary between the side surfaces of the two unit bodies.
Are provided on each side.

Two may be provided. The drift prevention device 22 shown in FIG.
Is composed of an annular fixed frame 22a protruding from the front surface or the rear surface of the unit main body, and a pile 22b slidably arranged inside the fixed frame 22a. By embedding the piles 22b in the ground of the river bottom, it is possible to prevent the barge from being swept away by the flow of the river. Further, even if the water level of the river changes, the pile 22b slides up or down inside the fixed frame 22a, so that the unit body can maintain a constant draft line with respect to the water level of the river. As the pile 22b, a prism or H-shaped steel made of a steel material or the like is adopted.
