本発明は、水面上に構築される人工地盤構造に
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an artificial ground structure constructed on a water surface.
水面上に人工地盤を構築する場合、極めて大掛
りな設備と面倒な作業とを要している。
When constructing artificial ground on the water surface, extremely large-scale equipment and troublesome work are required.
そこで、水面上に簡単に人工地盤を作る手段と

工地盤本体を水に浮かせ、海底や川底等にアンカ
ー等を打ち込んで、人工地盤本体を水面上に固定
したものがある。 Therefore, as a means to easily create an artificial ground on the water surface, the artificial ground body is formed into a floating structure, the artificial ground body is floated on the water, and an anchor etc. is driven into the seabed or riverbed, and the artificial ground body is raised above the water surface. There is something fixed.
また、前記従来の浮体構造の人工地盤は、一般

In the artificial ground of the conventional floating structure described above, the buoyancy is generated by the air surrounded by the steel plate or concrete outer shell that forms the box, so there is a risk that it will sink if the outer shell breaks.

安定性が悪く、このためかかる人工地盤の利用も
極めて狭い範囲に限られていた。 In addition, if the artificial ground body is formed into a floating structure, this artificial ground body is floated on water, and an anchor or the like is driven into the water bottom to fix the artificial ground body on the water surface. Due to the movement of water, the artificial ground moves up and down, back and forth, left and right, resulting in poor stability, and for this reason, the use of such artificial ground has been limited to extremely narrow areas.

In order to solve the above-mentioned problems, the present invention provides an artificial ground body having a floating structure in which a core formed of reinforced concrete is made of a foamed organic compound such as expanded polystyrene, and a plurality of artificial ground bodies formed at appropriate locations on the artificial ground body. We adopted a structure consisting of support piles that movably fit into the through holes and support the artificial ground.

鍔を有する支持杭とからなる構成を採用した。 In addition, the artificial ground body has a floating structure in which a core formed of reinforced concrete is filled with a foamed organic compound such as expanded polystyrene, and the artificial ground body is movably fitted into a plurality of through holes formed at appropriate locations in the artificial ground body. A structure consisting of a support pile with a support flange that contacts and supports the bottom of the artificial ground body was adopted.

支持され、安定した人工地盤が得られる。 In addition, this artificial ground body is manufactured in a factory, etc., floated on the sea, towed and transported to the artificial ground installation site, and at that location, support piles are inserted into the through holes formed in the artificial ground body. By burying the lower end of the pile in the bottom and supporting the artificial ground main body on the support pile, the artificial ground main body is supported by the support pile with movement in the front and rear and left and right directions, that is, horizontal swing. , a stable artificial ground can be obtained.

When burying this support pile 5 in the seabed, it is sufficient to bury it in the seabed sand 10 (Fig. 5, Fig. 7, Fig. 8), or it can be buried in the seabed support layer 11 below the seabed sand 10. It may be driven and buried (Fig. 6), and the selection is made depending on the type and scale of the artificial ground and other conditions.

つても十分に支持できる。 The artificial ground body 1 may be supported by the support piles 5 at a distance from the sea (water) surface 9 as shown in FIGS. 5 and 6, or may be supported away from the sea (water) surface 9 as shown in FIGS. In this way, a part of the artificial ground main body 1 may be submerged in water, and the lower limit of the artificial ground main body 1 is supported, and the vertical movement above the lower limit may be supported freely. In this case, since the artificial ground body 1 receives a buoyant force in the vertical direction, the supporting force of the artificial ground body 1 by the support piles 5 is sufficient to support the above-mentioned buoyant load or more, and the artificial ground body 1 receives the buoyant force by that amount. Compared to support piles that support the main body 1 away from the sea (water) surface 9, even thinner piles can sufficiently support the main body 1.
