Description

[Detailed Description of the Invention] Industrial Application Field This invention is a deep underground spiral tunnel that is implemented for the purpose of securing sufficient underground parking space for the large number of cars that overflow on the roads in densely populated areas. Park in the parking lot.

Conventional technology.

Currently, traffic congestion and frequent traffic accidents are becoming chronic on roads in densely populated urban areas, with no quantitative solution to the traffic problem found, and this will become a major issue in the future. .

Currently, large-scale parking lots in urban areas include metered street parking lots, multi-storey warehouse type parking towers, and self-propelled or mechanical underground parking lots.

The problem that the present invention aims to solve is that although many large-scale parking lots as mentioned above have been constructed and used for a long time in the current urban areas, there are still many parking lots on the roads. I! The shortage of z-bases is indescribable, and traffic jams and traffic jams caused by a large number of illegally parked cars
Accidents are occurring frequently, and this is an rR problem that needs to be solved.

Means for Solving the Problems As a means for solving the problems of the above-mentioned prior art, a deep underground spiral tunnel type parking lot according to the present invention is connected to a road 1 above ground, as shown in the embodiment in the drawings. approach tunnel 2.9, followed by spiral tunnels 3, 3' that revolve around a nearly vertical center line.
and two or more spiral tunnels 3, 3' installed in parallel.
an access tunnel 4 that connects the
It consists of an elevator 5 that directly connects the spiral tunnel 3 and the ground, and is characterized in that a roadway 6 and a parking space 7 are provided inside the spiral tunnel 3.

The driver goes down to the parking position of the car 8, gets back into the car 8, and starts out from the parking space 7 onto the road 6, passes through the approach tunnel 9, and exits onto the road 1 on the ground.

When the spiral diameter of the spiral tunnel 3 is increased, the curvature of the curve on which the automobile 8 is driven becomes larger, making it easier to drive, and at the same time, the tunnel becomes longer, and the parking space 7 increases proportionally.

The parking space 7 can also be increased proportionally by constructing the spiral tunnel 3 deep and long underground.

A car 8 wishing to park enters the approach tunnel 2 from the road 1 on the ground, proceeds to the driveway 6 of the spiral tunnel 3, finds an empty parking space 7 beside the driveway 6, and parks the car 8. Park. The passengers who got off the car use elevator 5 to return to the ground. Alternatively, the crew members who have finished their errands on the ground may use the elevator 5 from the ground.

FIG. 1 shows a twin-type underground parking lot in which a pair of spiral tunnels 3, 3-, which go around a vertical center line, are constructed with a suitable distance left and right. The spiral tunnel 3 on the left side of the figure is configured as an entry side, and the spiral tunnel 3' on the right side of the figure is configured as an exit side. The upper end of the spiral tunnel 3 on the approach side is constructed in series with an approach tunnel 2 for approach connected to the road 1 on the ground. The upper end of the spiral tunnel 3' on the exit side is connected to an approach tunnel 9 on the exit side that also leads to the road 1 on the ground. The two left and right spiral tunnels 3 and 3' are connected in series through a substantially horizontal access tunnel 4 at their lower ends (and at multiple locations along the way).

Therefore, this underground parking lot has a one-way structure, and cars always enter the spiral tunnel 3 from the approach tunnel 2 on the left side in Figure 1, and then park in an appropriate parking space 7 provided along the roadway 6. Find an empty space and park. Spiral tunnels are constructed with a nearly constant curvature, making driving easier and safer.

Cars leaving this underground parking lot must pass through access tunnel 4 and enter the 1st t! Spiral tunnel 3' on the right side of the l
Pass through and exit to the ground through approach tunnel 9 on the exit side.

The approach tunnel 2.9, the pair of spiral tunnels 3.3', and the access tunnel 4 described above are all constructed using a well-known tunnel cutting technique using a shield machine. The diameter of the shield tunnel is 6~
The spiral tunnel 3.3' is constructed with a diameter of about 12 m and a spiral diameter of about 100 m, but it is possible to construct a spiral tunnel that reaches 100 m underground.

As shown in FIG. 2, the interior of the spiral tunnel 3.3' is constructed with a partition slab 11 that horizontally partitions the cross section of the tunnel approximately in the middle. 6 and parking space 7 and 2
The tunnel is divided into two major sections, and both are arranged parallel to each other in the longitudinal direction of the tunnel.

Therefore, as soon as a car 8 running on the roadway 6 finds an empty parking space 7, it can drive into the parking space 7 beside the roadway and park there. Alternatively, the parked automobile 8 can voluntarily enter the road 6 again and return to the ground as soon as the occupants have finished their business.

Beside the parking space 7, there is a footpath 2 that allows passengers to exit the vehicle 8h) or return to their vehicle 8.

In the space 'F@' from the partition slab 11, a horizontal floor is also constructed to create a spacious promenade 13 exclusively for pedestrians.
is provided. The second promenade 13 is mainly used for passengers who get off the car 8 in the parking space 7 and descend from the footpath 12, or for those who are bothered by the exhaust gas and noise of the moving car. This is a road for walking long distances in a good environment without getting caught. It is therefore advantageous for this promenade j3 to be constructed as a moving walkway for those in a hurry or to help walk long distances.

Approximately the center line of the spiral tunnels 3 and 3' (or the innermost part of the spiral is located at the outer position and parallel to the center line) is located between the ground and the deepest part of the spiral tunnels 3 and 3'. A high-speed elevator 5 is installed that connects vertically. This high-speed elevator 5 and spiral tunnel 3.3'! The % deep part and a plurality of suitable depth positions in the middle are connected by a substantially horizontal communication passage 14. The communication passage 14 is connected to the spiral tunnel 3 or 3', particularly on the promenade 13 side. Communication passage! It would be convenient to install a moving walkway in 4 as well. The upper part of the high-speed elevator 6 is connected to the underground mall and above ground by escalators and passageways.

Embodiment (1) of the pond The spiral tunnel can be implemented as a double-spiral configuration in which a spiral tunnel on the entrance side and a spiral tunnel on the exit side are connected in series to form a composite configuration.

(2) Spiral tunnels include not only spirals with a circular planar shape as shown in Figure 1, but also spiral tunnels that have an oval or elliptical planar shape by connecting the two left and right spirals shown in Figure 1 tangentially. It can also be carried out with a formed spiral. This will dramatically increase parking space.

(3) What is the configuration inside the spiral tunnel 3.3'?

It can also be implemented as a two-lane type, with the area corresponding to the median strip serving as a parking space, and two roadways 6°6, one for going up and the other for going down, on both sides.

(4) All occupants should disembark at the entrance and exit of approach tunnel No. 2.9, and all operations including entry and parking of the vehicle into the spiral tunnel and exit of the own OX shall be carried out as an automated mechanical mobile system. You can also do it.

The effects of the present invention are as described in detail in conjunction with the embodiments, and according to the deep underground spiral tunnel type parking lot according to the present invention, it is possible to park many cars that are overflowing on the ground in urban areas. Ample space 7 can be secured underground, thereby eliminating illegal parking on above-ground tyas, improving road functionality, and contributing to #, vi, traffic accidents.

Not only that, but it is also possible to eliminate parking space from above-ground buildings, allowing the building to be used more effectively by the amount of parking space that was previously available.
