The winding devices vary the effective length of the ropes to adjust the depth at which the tunnel is submerged. The water ballast on the tunnel is varied by a weighing device responsive to the tension in the ropes to control pumps which pump water to and from ballast compartments in the tunnel.

RELATED APPLICATION This application is a continuation-in-part of applica tion Ser. No. 252,944 filed Jan. 21, 1963 now abandoned.
BACKGROUND OF THE INVENTION This invention relates generally to a novel underwater floating tunnel construction particularly useful in jet train transport systems, but applicable to any type of transport systems constructed in lakes, rivers, etc.
SUMMARY OF THE INVENTION It is the primary object of this invention to provide underwater suspended transport tunnels suitably anchored at a desired depth to resist the buoyant effect of the water which tends to displace the tunnel upwardly. This tunnel construction may be suspended at any desired water level out of the influences of waves and ships passing through the water. The tunnel is advantageously placed at a depth providing surroundings of very favorable temperature and pressure conditions and isolated from the eifects of earthquakes.
Another object of this invention is to provide an underwater tunnel system constructed of prefabricated tunnel units made from waterproof building materials such as reinforced concrete or prestressed concrete, metals or plastics in suitable dimensions to provide the jet train transport system. Such construction avoids the necessity of conventional boring and supporting structures used in prior art systems. Prefabricated tubular units can be made longer due to very small expansion because of its placement in most favorable surrounding conditions.
Another object is to provide underwater tunnel construction having installation and storage rooms for machinery utilized in placing the tunnel units at the required depths, for receiving water ballast in and out of the tunnels, for ventilation, and for emergency entrance and exit openings into the tunnel system.
Another object is to provide underwater tunnel construction having an anchorage system including a plurality of parallel flexible ropes which cause the tunnel floor to remain horizontal even though it may move within the body of water.
Another object is to provide a tunnel anchor system ineluding a foundation imbedded in the floor of the body of water and flexible anchor ropes connecting the tunnel to the foundation.
Another object is to provide a waterproof and, if desired, flexible connection between adjacent tunnel units which comprises a plastic waterproof ring sheet secured between two metal plates to permit some relative movement between adjacent tube units, the degree of movement being limited by adjustable tie-ropes.
Another object is to provide underwater tunnel construction having automatic regulation of water ballast by means of pumps operated in response to instruments measuring the tension in anchor ropes and to signals of traflic patterns of approaching transport.
Other objects and advantages of this invention will become apparent upon reference to the accompanying description when taken in conjunction with the following drawings wherein:

FIGURE 9 is a longitudinal section view for the flexible connection between adjacent tunnel units spaced from each other;
FIGURE 10 is a section view of the rigid connection between adjacent tunnel units illustrated in FIGURE 5.
DESCRIPTION OF THE PREFERRED EMBODIMENT Before proceeding to a detailed description of the drawing, it should be noted that the suspended underwater tunnel transport system of the invention functions on the principle that, when the transport load in the tunnel changes, the buoyant effect of the water tending to surface and push the tunnel upwardly also changes, which changes are reflected in the tension in the anchor ropes holding the tunnel in the submerged condition. The ballast on the tunnel can be regulated automatically by heavy pumps which pump water in and out of the tunnel tubes, the pumps operating in response to measuring instruments sensing the tension in the anchor ropes or in response to an information service about the transport load moving through the tunnel.
Referring now to FIGURE 1, the underwater tunnel system comprises two tunnel tubes 1 enclosed within external walls 2, each tube having beams 3 supporting a floor 4. Center space 5 located between tubes 1 serves as a corridor and exit from the tubes, houses mechanical machinery such as water pumps, windlasses, etc. and instruments such as manometers for the pumps to obtain the required stresses in anchor-rope 12, and also receives some ballast water pumped in by the pumps. Door 6 connects the tubes to space 5.
Positioned within space 5 are windlasses 7 driven through coupling gear 8. Also positioned within space 5 are ladder 9, and ventilation and exit shafts 10 having metal walls 11 and communicating with tubes 1 through ventilating pipes 20. If no ventilation shafts are necessary, a waterproof cover may be provided over the manhole at the top of space 5.
An important aspect of the invention is that the anchor ropes 12 be arranged parallel to each other to maintain the tunnel fioor in a horizontal level position even though the tunnel may shift laterally as shown at 19 in FIGURE 1. The number of anchor ropes used varies, but, in any event, ropes 12 should be provided at least at the ends of each tube 1.
The anchoring foundation 13, 14 illustrated in FIG- URES 1, 2 and 3 is suitable in very hard and stable ground, such as rock foundations, which will retain the concrete 14. A cross beam 33 connects anchor rods 13 to ropes 12.
In FIGURE 4 a ballast anchor including a weighted loaded vessel 34 imbedding itself below ground floor 21 is provided and is particularly useful when the ground soil is very soft and sandy.
In another control arrangement, the pumps may be operated in response to an information service regarding the amount of traffic or transport load through the tunnel.
The embodiment of FIGURE 2 illustrates an underwater tunnel having six tunnel tubes, tubes 22 for a jet train, tube 23 for two ordinary railways, two tubes having sections 24 and 25 each with three car lanes, and tube 26 for two lanes of heavy trucks. The tunnel is also provided with ventilation shafts 29, stairs 30, and operating machinery 32.
The prefabricated tubular members which are joined together to form the underwater tunnel may be rigidly connected as in FIGURES 5 and 10 or flexibly connected as in FIGURES 6 to 9.
In FIGURES 6 to 9 the tubes 37 and 38 have their ends connected by an elastic waterproof ring-sheet 41 fastened to each of the tubes by a metal band 40, the ring-sheet permitting some relative adjustable movement between the tube ends. Tie- ropes 42 and 43 also connect the adjacent tube ends and serve to adjust the relative position of the ends and limit the spacing d therebetween. Bolts 44 fixed in the end of tube 37 pass into aligned holes 46 of tube 38 to prevent rotational movement between tubes 37 and 38 and properly align the tubes. This flexible connection enables the tubes to be joined so as to angularly deviate from each other, for example, to slope downwardly away from each other (FIGURE 6) or upwardly away from each other (FIG- URE 7). Additionally, because the tubes may move slightly upon impact by an external force, cracking or rupturing of the tubes is substantially reduced.
In FIGURES 5 and 10 the tubes are rigidly joined together by bolts passing through flanges 47. For assembly purposes, a waterproof plastic sheet 45 is temporarily placed over the ends of each of the tubes to prevent the inflow of Water.
The underwater tunnel is constructed by first placing the anchorage 14 or 34 in place in the ground floor 21 and connecting anchor ropes 12 thereto. The prefabricated tubes 1 are launched into the water, their ends closed by temporary plastic sheets 45. Anchor ropes 12 are connected to windlasses 7, and water ballast is pumped into the ballast compartments to enable the tube to be submerged to the desired depth D beneath the water surface 16 as the windlasses are operated to wind the ropes 12. The tube is then connected to the end tube of the already constructed tunnel portion by properly aligning and placing bolts 44 into the corresponding openings 46, connecting the waterproof ring sheet band 41 around outside of the adjoining ends of the tubes, and tieing the opposed ends of the adjacent tubes together by the tie ropes or chains 43. When the ends of adjacent tubes are so connected, the end covering sheets 45 are removed to provide a continuous underwater tunnel passage.
The invention may be embodied in other specific forrns without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
