TECHNOLOGY
1. Advantageous/Features of Round Shape Structure
1. Round structure features high strength.
- Pursuit of function made us achieve this parking system with streamlined design.
- Making the best use of limited space, this cylinder shaped parking facility realized not only simplicity but also high effectiveness and safety.
- Round shape has earthquake-resistance and quake-absorbing structure to restrain tremors or shakes, which won’t be influenced by the direction of seismic wave. The small deformation and no tension force enable the wall thinner.
2. Total cost is drastically reduced (Compare with Conventional Building Parking)
- Compared with the same sized underground garages, the amount of earth from drilling is smaller and no curing is required thanks to the round shape.
- The necessary land space is only one third(1/3) of the conventional parking garage where drivers park by themselves.
- Drilling and immersion can be done simultaneously and construction time is shortened. We have succeeded in reducing the cost by one fourth(1/4) of that of the underground parking where drivers park by themselves.
- The shorter construction term contributes to cost reduction.
3. Shortening construction term
- As this system uses press in caissons built beforehand in a factory, construction is undertaken very speedily.
- Round structure makes construction time shorter than that of the same sized underground parking facility.
- Machine installation is so simple to assemble on the site, which also means easy dismantlement as well as easy relocation.
- The short working time leads to the overall cost reduction.
4. Small space per car (VS. Conventional Building Parking)
- As the place where cars are converged is in the center of the round shape, space per car is small.
- It requires only 28 % of land space compared with the existing underground parking system where drivers park by themselves.
- The effectiveness of car capacity is three times and half (×3.5), while the construction cost is one fourth (1/4) !
- Other empty space can be utilized as a reservoir.
5. Small space per car (VS. Square Shape (Linear type) Automated Parking)
Round shape has more advantages
Comparison in case of parking 10 cars on one floor
- About 270 ㎡ / floor
- 27 ㎡ per one car (100%)
- Center space has to be left open for car movement.
- About 240 ㎡ / floor
- 24 ㎡ per one car (88%)
- Fan shaped space is left open, but it can be utilized for a reservoir, an electric room and so on.
* Round shape is reasonable for car placement.
| Occupation Area (㎡/car) | |
| Round type parking | 24 |
| Linear type parking | 27 |
| Conventional parking | 35-42 |
6. Civil cost is reduced (VS. Square Shape (Linear type) Automated Parking)
Round shape has more advantages
Comparison in case of parking 60 cars on each system
- About 3,780 ㎥/ system/ 60cars (18m×15m×14m=3,780㎥)(100%)
- 3,780㎥ × @500$ = 1.89million$
- 1.89million$ / 60cars = 31,500$/ car (100%) *case in Japan
- About 3,366㎥/ system/ 60cars
(17.5m×14m=3,366㎥)(89%) - 3,366㎥ × @350$(30% down from 500$) = 1.18million$
- 1.18million$ / 60cars = 19,600$/ car (62%) *case in Japan
* Round shape is much reasonable for Civil Cost.
| Cost for civil work (US$/car space) | |
| Round type parking | 19,600 $ |
| Linear type parking | 31,500 $ |
| Conventional parking | 250,000$ |
7. Other empty space can be utilized as another purpose space (VS. Square Shape)
Round shape has more advantages
Comparison in case of parking 60 cars on each system
Round shape has other empty space can be utilized as a reservoir (Rainwater storage tank or Fire prevention water tank), an electric room, Luggage warehouse and so on.
- O ㎥
- 3 ㎥ × 12m =36 ㎥,
36 m3 × 10space =360 ㎥/system
*Capacity of 36 fire engines water,1 fire engines = Capacity : 10,000 L
| Type:60cars | Utilized Area (㎥/system) |
|---|---|
| Round type parking | 360 (360,000Liter) |
| Linear type parking | 0 |
| Conventional parking | 0 |
Technology infomation
1. Structure (shape) is most effective. The structure is advantageous
In case of square type
- Concrete is strong against the compression, but week against the tensile strength.
- [Concrete is easy to deform] & [Tensile strength arises] → Wall becomes thicker
In case of round type
- Small rate of deformation.
- No tensile strength arises → Wall becomes thinner.
2. Short construction period
In case of square type
Outline process
Building of continuation wall under the ground
Excavation
Construction of open caisson method on the spot
Framework → Concrete casting → Concrete cure → Framework removal
Removal of temporary equipments
In case of round type
Outline process
Construction of the first excavating area
Excavation
Assembling of pre-cast segment
Simultaneous work of excavation and placing
Repeat 
Assembling of pre-cast segment
Characteristics
- No temporary facility necessary
- No time for concrete cure and others necessary
- Drilling and placing can be done simultaneously
- Reduction of the amount of earth
→ Shortening the work period → Reducing the cost
3. Utilization as a building foundation
Parking lot can be used as a building foundation
Characteristics
- When newly constructing or renovating hotel/office buildings and public facilities, the round parking system can be installed as a foundation element of the superstructure as well as a providing sufficient parking capacity.
- The round parking system will increase the value of high-grade residences or apartment houses in combination with a safe, convenient and environmentally friendly parking system.
