🪄How did the USJ Harry Potter zone come from??

Creation

The Wizarding World of Harry Potter Zone

Universal Studio Japan (USJ)

It's a very challenging project.

Because it's not just about building regular buildings.

But the creation of a "gigantic work of art."

Designed based on the magical world.

And still have to pick up the tremors.

From earthquakes by Japanese standards, too.

• • Construction around the world Ep.6 • •

This is considered a tourist attraction.

Long popular.

Knowing the origin of construction

Maybe it'll give you a funnier view.

When traveling in the future

Today I will raise some interesting issues.

Let's talk.

🟠. Area management.

✔️ soil quality improvement.

It's an engineering problem.

(Geotechnical Engineering)

The hardest place.

Because the original area is

"Soil formed by sea reclamation."

Osaka Bay Area

Which is very soft clay.

(Soft Marine Clay)

And there's a high risk of liquid soil.

When there's an earthquake, sir,

It takes a combination of techniques to

"Change the lane

To become a strong concrete floor. "

The techniques used are as follows:

🌊 Accelerate subsidence with the Vertical Drain Method.

Because of the clay below the ground.

There is a lot of water inserted.

If the building is overlaid

The soil will slowly collapse for years to come.

Therefore have to force the soil

To finish collapsing before building.

• Use Sand Drains / Plastic Board Drains technique

Use the method of plugging many drainage rods.

In the dirt. Vertically.

To be a shortcut.

Causing the water to be depressed

Drain out faster.

• Continue with Preloading / Surcharge Techniques

As soil conduction

Or a stone of enormous weight.

Let's put it on top.

To press the water out of the clay.

Like squeezing a sponge

Until the soil is tight to the desired level.

Then remove the soil

To start construction.

⚙️ build a cement mix earth pile.

(Deep Mixing Method - DMM)

In an area that requires enormous weight.

Like Hogwarts Castle.

Because waiting for the soil to collapse alone may not be enough.

• This method is to use machines.

Drill into the ground.

Then spray the mortar

Mixed with the same soil in there

The result is

"Pile soil mixed mortar."

Many times stronger than the original soil.

Spread full ground under the foundation.

To help carry weight and protect against tilting buildings.

⚙️ liquid soil protection.

(Liquefaction Mitigation)

In that Osaka Bay,

A layer of sand that reclaimed

There is a chance of becoming liquid.

When hit by the earthquake tremors,

Which can cause the player to sink or crash.

• Sand piling is nailed

Into the original sand soil layer.

With high tremors.

Sand Compaction Pile (SCP)

To compress.

Let the grains of sand line up as tightly as possible.

So there's no room for water to insert.

• A pebble pillar has been inserted.

To help drain the soil water pressure out quickly.

Reduce the likelihood that land will become liquid.

⚙️ soil pollution management.

This area used to be a heavy industrial area.

(Steel plant)

This makes the soil heavily contaminated with metals.

like lead, arsenic.

• Before building

So toxic soil must be dredged.

Go to rigorous treatment or blocking areas.

To ensure that

The dirt in that theme park.

Safe to visitors

And the environment in the long run, sir.

.

.

🟠 Building a building in the Hogwarts zone.

"Twisted" or "Close to breaking"

(Themed Crooked Constructions)

According to the manner described in the book,

But still have to maintain the highest level of security.

It's a collaboration between

Architects and structural engineers

Using the following main techniques

🔧 "perpendicular" internal structure.

But the outside "deceived the eyes."

The key secret is

Most of the main structures

Still steel poles and beams.

That's upright and strong.

According to engineering, sir.

• There are extensions.

"Reinforced Steel Frame" (Outriggers)

Out of the main structure.

These auxiliary frames

Will be bending or placed degrees to tilt

According to the desired design

• Even the outside looks distorted

But the weight calculation

Will always be transported back to the upright pillar.

So that the counterweight center of the building remains stable.

🔧. Use a lightweight GFRC wall.

Traditional plastered masonry is not used.

To make that distorted shape

Does not overload the structure.

• GFRC

(Glass Fiber Reinforced Concrete)

It's a concrete mix of glass fibers.

That was cast in sheets in the factory.

These plates.

Can cast to have cracks

Fissures or exposed skin

Like an old stone can follow the mold

• These wall plates

Will be brought to hang.

With a tilted steel frame.

(Panelized System)

Causing it to look from the outside like a tilted building

But it's actually a shell.

The steel structure is covered.

🔧 illusory technique.

• Buildings that look taller than reality

Like a castle tower.

Will be designed to make the top smaller.

And use fake stones.

Smaller and smaller as they get higher.

• Window degrees are placed

Or the chimney to tilt unevenly.

Will make our brains feel that

The building is more twisted than reality.

🔧 latched hole access points are used.

(Slotted Holes)

Or a slightly moving joint.

To provide external wall plates.

It can expand or shrink.

By the weather.

And tremors.

Without making the skin of the "fake stone."

A crack really happened.

Building Making

"Seems to fall, but not fall."

So it's a combination of

Accurate calculation

And a smooth staging.

That's it.

Think about work. No time.

Or housing problems. Think about it.
