(See Japanese Patent Publication No. 247474 and Japanese Patent Laid-Open No. 63-261070, etc.) In addition, Japanese Patent Publication No. 42-11394 discloses that an endless tunnel is constructed by a shield construction method, and a plurality of loading platforms for parking are connected to an endless chain conveyor. It describes a tunnel parking system in which vehicles are mounted and circulated from the entrance to the exit.

[Problems to be Solved by the Invention]

By the way, when constructing an underground parking lot under a road or the like, conventional construction has been performed by an excavation method using an earth retaining wall such as an underground continuous wall. However, in the case of the excavation method, there is a disadvantage that work can be performed only at night when traffic is low until the road surface excavated to a certain depth is temporarily covered to minimize traffic blockage on the ground during road excavation. . In addition, when constructing an underground parking lot under a river, it is necessary to turn around the river during construction, temporarily collapse the river bank, and restore these after the underground parking lot is completed.

Further, the tunnel parking system described in Japanese Patent Publication No. 42-11394 mentioned above uses a shield tunnel to solve the drawbacks of the excavation method, but the circular tunnel cross section is simply used as a parking and transport space. Since the conveyor on which the loading platform is placed is circulated, the efficiency of loading and unloading and transportation is poor, and the self-propelled section of the entrance / exit requires construction by excavation.

The present invention is to solve the problems in the prior art as described above, it is possible to effectively use the space under the road, it is possible to perform efficient construction while minimizing traffic interruption in construction, and The purpose of the present invention is to provide a structure of an underground parking lot having a high movable efficiency as a parking lot.

[Means for Solving the Problems]

The underground parking lot of the present invention uses a shield tunnel having a predetermined cross section and a predetermined length constructed in the ground by a shield machine as an underground parking lot space.

In this shield tunnel, a shaft (corresponding to claim 4) or a connecting running path (corresponding to claim 5) is provided for communication with the ground, and an entrance / exit is constructed in this portion, and the vehicle is parked at a predetermined parking position. Vehicle transportation equipment will be provided for transportation and parking.

As the vehicle transportation equipment, an elevating device for vertically transporting the vehicle and a horizontal transportation device for horizontally transporting the vehicle are installed.

Inside the shield tunnel, a plurality of parking areas are provided in upper and lower stages, and vehicle transportation lanes are provided in parallel with each other. Lifting devices such as lifts will be installed at required positions in the vertical shaft and shield tunnel to connect the inside of the tunnel with the ground or between parking areas divided into multiple stages.

As the horizontal transfer device, a conventional one used in a mechanical parking lot, for example, a type in which a pallet carrying a vehicle is placed on a trolley to move, etc. can be used. It can be transported to a predetermined parking area and parked.

Further, regarding the parking area and the vehicle transportation lane, as described in claim 2, the parking area is provided in a plurality of upper and lower steps on both sides of the tunnel cross section in the shield tunnel, and the vehicle transportation lane is provided in a plurality of upper and lower steps at the center of the tunnel cross section. By combining the upper and lower vehicle transport lanes, it is possible to improve the efficiency of loading and unloading. In addition, the space left above and below the vehicle transportation lane can be used for stock areas and other purposes.

The parking lot in the shield tunnel may be fully mechanical from the entrance to the parking position, or may be partially self-propelled semi-mechanical. In addition, as described in claim 3, when a vertical multiple shield tunnel is used as the shield tunnel instead of the tunnel having a circular cross section, the upper portion may be self-propelled and the lower portion may be mechanical.

Furthermore, regarding the cross section of the shield tunnel,
It is also possible to use a horizontal multiple tunnel shield tunnel or vertical multiple tunnel shield tunnel in which circular cross sections are overlapped in the horizontal direction, and the cross sectional shape is not particularly limited, depending on the diameter and capacity of the shield machine. And
