Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a marine railway laid through water.

In order to build a railway, securing land and purchasing land for that purpose requires enormous costs.

This invention is aimed at the construction of a railway under the sea, where it costs almost nothing to secure or acquire land.The purpose of this invention is to greatly reduce construction costs. The objective is to provide a marine railway that can reduce the

Other objects of the present invention are, in particular, a means for supporting underwater pipes for laying railways in a vibration-proof manner, and a means for maintaining normal trackways connecting land and water without being affected by the ebb and flow of the tides. It is about providing the means.

The marine railway according to the present invention is a railway that is laid through water, and the underwater route is a pipe body that has a diameter that allows the railway to be laid, and the appearance of the pipe body that contains equipment for laying the railway and other equipment. Adjustment means for making the specific gravity equal to the specific gravity of seawater is incorporated, and the support means for the underwater tube is provided with struts that protrude downward in parallel to the floating body that is floated and held by buoyancy on the water surface, The strut elastically supports a hydrofoil plate that is movable along its longitudinal direction via a spring, and the hydrofoil plate supports the underwater tube, which is a movable structure that connects land and water. A bridge is a floating bridge that connects land and water by at least two floating bodies that can swing freely, and a plurality of beams are arranged on the floating bodies so that one end serves as a pivot point and the other end serves as a free end. It is characterized in that it is constructed in such a way that the lines are laid one on top of the other, and then a line of a required length is laid abutting against each other.

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

In Figures 1 to 5, reference numeral 1 denotes a tube body made of steel, other materials, transparent materials, etc. that has a diameter that allows railways to be laid. Corresponding roads, water pipes, gas pipes, electric lines, and optical transmission lines will also be installed.

In order to install the pipe body 1 on the bottom of the water, use a bottom sweeper or the like to lay it down while smoothing the unevenness of the bottom of the water. At that time, both ends of the tube are placed on land or on a ship and exposed to the atmosphere.

Of course, if there is a possibility that gravity or external force such as shearing force may be generated on the tube, it is necessary to take appropriate measures in advance to prevent excessive force from acting on the boat or float.

Necessary air, water, electricity, etc. inside the tube are brought in from outside, and unnecessary items are sent outside.

If a large amount of water leaks into the pipe, a short circuit in the current flowing between the left and right rails will be detected.
A stop signal is displayed by detecting it with a flow direction meter, thereby causing trains, cars, people, etc. (hereinafter referred to as moving objects) to stop, and moving objects to move backward.

When a stop signal is issued due to water leakage and it becomes clear that there are no moving objects in the area, the lock on the watertight door installed inside the pipe is automatically unlocked by electrical means or other means. I'll keep it. If a spring is attached to the hinge of the waterproof door, it is possible to close the waterproof door automatically, thereby stopping the flow of water and protecting the safety of moving objects.

In addition, by providing a large number of waterproof doors in the pipe body and using them to fill the hollow pipe body with an appropriate amount of water to make the apparent specific gravity of the pipe body equal to that of water, it is possible to , it is also possible to reduce the generation of external forces such as shearing forces on the tube body.

On the other hand, in the event of a water leak, workers wearing diving suits, etc., open the small work doors installed in each waterproof door one after another, enter the area where the water is leaking, and drill into the leak hole. The line will be opened to traffic after filling in and completing leakage prevention work.

FIG. 1 shows the state in which the pipe body 1 is installed at the bottom of the water, and the pipe body 1 is placed in the second to fourth positions.
As shown in the figure, struts 6 and braces 62 are placed on the bottom of the water.
erected and laid in or on water. FIG. 5 shows the track 3 supported on water.

In the above case, the pipe body can be used as an underwater bridge, and buoyancy acts on the supports and the underwater bridge, and the water pressure acting on the pipe body is less than that of a bottom pipe, so generally speaking, Economical design is possible. If a lateral force is applied to a strut or the like, braces 62 are installed.

To attach a mounting member or something like a pipe to the support, it is necessary to use protrusions provided on each member,
Use holes, screw holes, etc., and use methods such as tying, bolting, welding, and gluing.

If the bottom of the water is hard and you cannot drive pillars or stakes into it, use the drill used to dig oil holes from above the water to drill the hole to the required depth, and after pulling out the drill, push the stakes in from above the water.

If individual pillars alone are not strong enough, conventionally known crescent pillars are used. In other words, use a pillar whose cross section is crescent-shaped, and use a drill to drill the next hole along the missing part of the previous crescent pillar, and when the drill is removed, the next crescent moon will be inserted. Insert the pillars along the missing part of the previous crescent pillar, and then insert the crescent pillars one after another to form a straight, polygonal, or circular wall, or to create a wall inside it. Formed by hardening with concrete.

FIGS. 6 to 9 show the state in which a tube body is fixed to the bottom of the water or underwater so that it will not sink in water even when a load is placed on it. That is, if the tubular body 11 cannot be fixed to the bottom of the water or underwater due to buoyancy or water current, the tubular body 11 is fastened to a stake or anchor bolt 50 that cannot be pulled out, as shown in FIG. 7th
~FIG. 8 shows the state in which the underwater tube 11 is fixed by the anchor bolt 50 and the wire 5. 9 and 10, a plurality of floating bodies 2 made of a suitable material are used, and a tube body 11 is placed on top of the floating bodies 2.
Alternatively, it shows a marine railway on which a track 3 is placed and laid using anchor bolts 50 and wires 5. The bracing member 21 attached to the floating body 2 is a reinforcing truss in the direction perpendicular to the railway line, and in addition to this, a horizontal reinforcing truss and a reinforcing truss in the direction of the railway line are also attached.

The reinforcing truss in three directions also has the function of connecting the floating body 2 together with bolts connecting holes provided at both ends of the floating body 2 so as not to disperse the floating body 2.

FIG. 11 shows means for horizontally supporting the tube in a vibration-proof manner. That is, a floating body 2 that is floated and held on the water surface by buoyancy is provided with a support 6 that projects downward in parallel, and a hydrofoil plate 15 that is movable along its longitudinal direction is attached to the support via a coil spring 65. The underwater tube body 11 is elastically supported by the hydrofoil plate 15, and
According to this configuration, the hydrofoil plate 15 and the spring 6
5, the underwater tube 11 can be supported in a vibration-proof manner.

Fig. 12 shows an example of supporting a railway line with a floating body, in which a floating railway line 3 is placed on a floating body 2, and an underwater tube body 11 through which an opposing line passes is attached below the floating body 2, and both lines are connected. It is formed in the shape of a meganebashi bridge using a linear integral truss. Crossing boats can pass through Meganebashi.

When the buoyancy of the floating body is insufficient, holes provided at both ends of the floating body are used to extend the floating body and the reinforcing truss in the left-right direction. The floating body 2 does not have to be an airborne body as long as it has buoyancy; for example, a light plywood can be used.

The pipe is used by pulling out the pipe that is no longer in use, and at the same time using the hole at the rear end of that pipe to connect the two pipes using the hole at the tip of the next pipe to be replaced. This is to make it easier to replace both pipes. There is no problem even if the tube has some protrusions or if it is not a tube as long as it does not pose a problem for this type of work.

The floating bodies 2 are usually arranged at right angles to the direction of the track, but they can also be arranged at other angles, or the angles can be changed when arranged in layers.

Further, the floating body 2 may have a circular shape instead of a straight line. If the floating body 2 has more buoyancy than necessary, install two or more pots out of the way so that water or air can be put in and out of the floating body 2 to adjust the apparent specific gravity. I'll keep it.

The track 3 supported on the water may be provided directly on the floating body 2 or on a bed of crushed stones or the like.

FIG. 13 shows a movable bridge that connects land and water. In other words, they communicate in a swingable manner. In other words, at least two
One floating body 2 forms a floating bridge connecting land and water, and a plurality of beams are sequentially stacked on top of the floating body so that one end serves as a rotation fulcrum and the other end serves as a free end. This is a configuration in which two lines are laid against each other, and according to this configuration,
Even if the floating body moves up and down due to the ebb and flow of the tide, the track can be displaced accordingly.

As described above, according to the present invention, it is possible to construct a railway with almost no cost for securing land or acquiring land.

In particular, according to this invention, it is possible to support the underwater pipe on which the railway is laid in a vibration-proof manner, and since the part connecting land and water is made into a movable bridge,
It is possible to construct a trajectory that is not affected by the ebb and flow of the tide.
