Description

TECHNICAL FIELD The present invention relates to a floating ground constructed on a water surface.

<Prior art> In recent years, when land shortages and soaring land prices occur, water ground is constructed on the surface of the sea, lakes, rivers, etc. It is a huge structure with one side of about 1 to 5 km, and is installed in a temporary or semi-permanent form.

The most problematic point here is how to install this floating ground on the water surface in a stable state without moving.

Therefore, conventionally, a large number of legs are hung vertically on the lower surface of the ground above the ground, and the lower end of each leg is brought into contact with the water bottom such as the seabed,
Means for mooring the ground above the water to the bottom of the water with a wire etc. are adopted.

<Problems to be Solved by the Invention> However, as is well known, since the water bottom such as the seabed has a lot of ups and downs, it is impossible to stably bring the lower ends of all the plurality of legs into contact with the water bottom.

Therefore, a bulltozer is run on the water bottom by remote control to level the water bottom and flatten it.
Depending on the location, it may not be possible to hit the bedrock and level the soil to the desired state. In addition, since it has to be performed over an extremely wide range, the cost is also high.

On the other hand, it is possible to fix the lower end of each leg to the bottom of the water, but it is rather dangerous and unstable due to the influence of waves. Therefore, it requires an extremely large amount of labor and cost to bury and fix it with a strength that can withstand the force of waves, and half-way fixing is likely to damage it.

Further, the permanent fixing also has a problem in that the ground above the ground cannot be moved to another place.

In addition, if the water bottom is soft ground, the foundation cannot be used unless the piles are struck to the hard ground, which is an extremely large-scale construction.

<Means for Solving Problems> The present invention has been proposed in view of the above, in which a large number of legs are vertically provided on the lower surface of the ground located on the water surface, and a substrate extending across the lower ends of the adjacent legs is provided. At the same time, the substrate is integrally formed with a connecting portion, and a support having elasticity in the longitudinal direction is provided at a side edge of the substrate, and the support stably supports the substrate on the water bottom in a soft landing state. It was done like this.

<Operation> Since the present invention has the above-described configuration, the substrate on the bottom of the water is provided by the elastic support provided on the side edge in the longitudinal direction of the substrate integrally formed by the connecting portion while straddling the lower ends of the adjacent legs. Can be stably installed in a soft landing state, and the ground can be stably constructed on the water surface.

<Examples> Hereinafter, the present invention will be described with reference to Examples of the drawings.

1 and 2 are a schematic side view and a schematic front view showing the basic structure of the present invention, in which the ground 1 has sufficient strength to install a facility such as a predetermined building, For example, it is a structure in which concrete is cast on an iron plate, and has, for example, a plate shape with a short side of 150 m and a long side of about 1000 m.

A large number of legs 2 are vertically provided on the lower surface of the ground 1, and a substrate 3 is provided in series at the lower end of each leg 2 along the longitudinal direction of the ground 1. In the illustrated embodiment, there are two
The legs 2 in a row are arranged in a row, the substrates 3 are individually provided at the lower ends of the legs 2 in each row, and the substrates 3 and 3 are integrally configured by a connecting portion 4 arranged at appropriate intervals. ing. Further, the ground 1 is gently inclined in a stepwise manner along the longitudinal direction.

Then, elastic supports 5 are provided on both side edges of the substrate 3 along the longitudinal direction. The support 5 is formed of a predetermined material such as rubber or synthetic resin so as to be contracted in a liquid-tight and air-tight manner, and has a length of about 600 m with respect to the ground 1 of 1000 m, for example. .

A filling material such as water, sand, or air is appropriately injected into the support 5 having the above-described structure to expand the support 5, and the expanded support 5 elastically supports the substrate 3 on the water bottom a.

The amount of the filler injected into the inside of the support 5, that is, the support 5
The degree of expansion of is determined according to the state of the water bottom a.

Then, the expanded support body 5 acts as a kind of cushioning material, and the ground 1 can be installed on the water bottom a in a soft landing state. In addition, if the ground 1 is moored with a wire or the like (not shown) in an anchor shape as necessary, the ground 1 can be in a stable state in which it does not move on the water surface.

The above-structured floating ground 1 can be arranged side by side in the lateral direction to construct a larger area floating ground. In this case, the support 5 not only supports the vertical load but also the adjacent substrates. 3 functions as a cushioning material that prevents collision damage.

FIG. 3 is a floating city model using the floating ground 1 according to the present invention, in which a large number of legs 2 are vertically provided on the lower surface of the ground 1, and a substrate 3 is provided at the lower end of each leg 2. There is. And
A support 5 is provided on the side edge of the substrate 3 in the longitudinal direction, and the support 5 stably supports the substrate 3 on the water bottom a in a soft landing state.

A city 6 is formed on the upper surface of the ground 1 so as to incline upward from one end in the longitudinal direction toward the other end, and the center in the width direction is gently depressed. The city 6 has an office portion 7 at the side edge, a square 8 such as a tennis court and a park, and a residential portion 9 at the center. On the other hand, in the ground 1 (underground), public facilities such as roads, parking lots, shopping centers, machine rooms, stockpiling warehouses, buoyancy adjusting rooms, etc. are provided, and in the illustrated embodiment, a quay 10 is provided at one end. .

If a plurality of floating cities 6 as described above are installed side by side and a bridge is installed between the floating cities 6 to connect them, it is possible to build a large city on the water. In this case, according to the present invention, since the elastic support 5 is interposed between the substrates 3 of adjacent cities, the substrates 3 do not collide with each other.

Although the present invention has been described with reference to the embodiments of the drawings, the present invention is not limited to the above embodiments and can be carried out in any manner as long as the configuration described in the claims is not changed. .

<Effects of the Invention> In short, according to the present invention, a support having elasticity is provided at the side edge along the longitudinal direction of the substrate integrally formed with the connecting portion while straddling the lower ends of the adjacent legs. Since the substrate is elastically supported on the water bottom, it is possible to stably support the substrate in a soft landing state in which the ground does not move on the water surface. Therefore, the ground can be installed on the water surface very easily and stably, and the cost is extremely low. Moreover, even if the ground becomes large, it can be dealt with by extending the support, so that the construction is easy, and the construction cost and the construction period can be shortened.

Further, when the floating grounds according to the present invention are installed adjacent to each other, the supporting members function as a lateral cushioning member, so that the substrates do not interfere with each other and are damaged. The present invention has many excellent effects such as being less affected by waves and being safe, and being able to move as needed.
