🌊 Engineering Marvels of the Panama Canal

The Panama Canal, a remarkable feat of engineering, utilizes an innovative locking system to elevate ships by nearly 20 meters, facilitating their passage between the Atlantic and Pacific Oceans. This system was made possible by the invention of giant T cranes, powered by steam locomotives and controlled from a small house above the crane, which could accurately lift and move a bucket filled with concrete. The construction of the canal was of paramount importance, as it allowed ships to save up to 20,000 kilometers of travel distance. The French initially attempted to construct the canal by digging through the terrain but faced numerous challenges including landslides, heavy rainfall, and disease, leading to the failure of their efforts and the loss of nearly 22,000 lives. The Americans later adopted a different approach, opting to remove only parts of the mountains and flood the area, thus avoiding the complete flooding of Panama. The canal's operation relies on a delicate balance of water levels, maintained by the Chagres River and local rainfall, which was threatened during the 2019 drought.

🚧 Overcoming Challenges in Panama Canal Construction

To enable the Panama Canal's construction, engineers had to devise a method to flood a specific region, leading to the creation of the Gatun Lake by damming the Chagres River. The challenge was to flood only the necessary area without submerging the entire country. The construction involved the removal of a 15-kilometer long strip of land, known as Culebra Cut, which required the use of massive machinery like track shifters, dirt spreaders, and unloaders. The steam shovel, invented by Bucyrus, played a crucial role, with 70 such machines being employed. The use of dynamite was also essential, with an average of 800,000 sticks used per month to break rocks into manageable pieces. The process of moving and unloading dirt was streamlined through the use of innovative machinery, including a steam-powered winch and a dirt spreader that could flatten the accumulated mounds of earth. The track shifter was another ingenious invention that allowed for the efficient relocation of railway tracks, saving both time and resources.

Transcripts

did you know that a simple drought in

the Panama region could cease the

operation of the great Panama Canal this

Marvel of civil engineering uses a

clever locking arrangement to lift

passing ships by almost 20 meters in

order to safely transport them across

the canal to materialize this smart

Canal lock system a super fast

concreting technology was needed look at

the giant T cranes the American

engineers invented they were moved by

steam locomotives and did you notice a

small house sitting above the crane

interestingly the steam engine inside

this house was able to lift a bucket

filled with concrete and also control

its movement accurately

this steam-powered cable pulley

mechanism delivered the bucket to its

destination much faster than manual

material transportation

the way it dumped the concrete was also

quite innovative

you might have already noticed how this

100 year old invention was able to move

the concrete bucket in all three

directions the Americans invented many

more incredible machines to complete the

Panama Canal project successfully

but the question is why is this canal

project so important

if you can connect the Atlantic and

Pacific Oceans via water the ships can

save a travel distance of 20 000

kilometers

the best location to achieve the canal

dream is a narrow region in the country

of Panama

Panama is a stunning country with very

rugged terrain this cross section of the

land is proof of that

the most obvious solution is to Simply

dig all of this out allowing the oceans

on both sides to rush in and connect

so ships can continue their voyage

the French tried this exact method in

1892 and failed miserably landslides

torrential rain and disease were the

main problems removal of the earth took

almost eight years and killed nearly 22

thousand people as a result the project

was eventually abandoned

the Americans came up with a brilliant

idea why should you dig the Earth

completely

just remove a portion of these huge

mountains and flood the entire length of

land with water

keep watching to learn how they filled

only a small width with water without

flooding the entire country of Panama

as you can clearly see as long as the

ship is raised onto this new elevated

water surface it can easily cross Panama

but how exactly did they make it

possible to raise a heavy ship to this

new water level Engineers relied on this

simple trick if an object can float on

water

just by increasing the water level

it will be lifted up

to implement this trick we must first

install three gates at the entrance of

the Panama Canal

assume the first gate is open

the ship enters the region between the

two gates

now close the first gate and open this

valve the water from the second chamber

is released both the water level and the

ship will automatically rise once the

water levels are equal open the second

gate so that the ship can effortlessly

enter the next chamber now close the

second gate and do one more water

leveling after a few more water

levelings the ship can now enter the

raised water platform effortlessly just

like that the ship can continue on its

long journey through this fantastic

shortcut through Panama

when the ship reaches the end of the

canal it must be lowered to sea level

again

in order to accomplish this simply

perform the same water leveling

technique in the exact opposite sequence

the ship has been lowered to the ocean

level

in this genius

this raising and lowering is a

completely gravity-based method no

external energy is needed for this

operation

however did you notice a small issue

here when the first ship entered the

canal the ocean and chamber water were

at the same level

however after it was fully raised up

an extra water step was formed in the

first chamber

this extra water must be released into

the ocean so that the next ship can

enter the chamber

this water step originally came from the

lake

therefore with the passage of each ship

the gatun lake loses water without

correcting this issue the gatun lake

would eventually dry up completely and

operation of the Panama Canal would

cease

luckily this is not the case

the gantoon lake is supplied by the

chagras river whose water comes from

local rainfall in the Panama province

as long as there is sufficient rain the

water loss that occurs during each ship

Crossing is easily compensated for

however the Panama Canal drought of the

Year 2019 scared everyone

the water level in Panama became too low

due to the drought some shippers were

forced to limit the amount of cargo in

order to safely navigate the Waterway

the next year there was sufficient

rainfall and the canal was functioning

optimally once again

now let's tackle the big question how do

we flood this exact region of Panama for

this we must first construct a dam

the water stream from the chagras river

will accumulate within the dam region

the newly formed water body is called

gatun Lake one of the largest man-made

Lakes

simply by controlling the dam height or

the height of the water surface we can

achieve different levels of flooding

unfortunately there is no way to flood

only this region if you try to flood the

entire Crossing almost the entire

country of Panama will be underwater

because of this American Engineers

decided to stop the flooding at this

level almost two-thirds of the land is

flooded and only a small portion remains

above water

now Begins the real challenge removal of

this 15 kilometer long unflooded region

or the formation of Culebra cut the

whole purpose connect the dam and ocean

water have a look at these gigantic

machines known as a track shifter

dirt spreader

and unloader interestingly they were all

invented for one specific purpose form

the calabra cut by removing the Earth

and connect the oceans the king of the

Panama Canal construction Machinery was

the steam shovel created by Bucyrus to

accomplish this Mega project 70 such

steam shovels were employed

even such a gigantic machine struggled

in Panama's Rocky terrain the right

solution is

usage of dynamite

a staggering eight hundred thousand

sticks of dynamite were used on average

per month during the major excavation

work

the dynamite effortlessly broke large

rocks into smaller pieces which could

then be easily scooped up by steam

shovels one scoop could move two tons of

dirt the way the dirt was dumped into

the train was so cool to watch

take a look at the power source of this

gigantic machine

a steam engine the way this steam engine

controls this machine is a classic

example of the incredible Innovations of

the early 20th century Engineers turned

the boom using a mount with a rope

around it

the Dipper stick was able to move to and

fro thanks to this interesting gear

arrangement

the Dipper stick could also rotate

because of this chain pulley arrangement

when the bucket was ready to dump the

material

the crane operator simply pulled the

latch

the wagons now filled with dirt could

start their Journey towards the dump

area

as it turns out even just emptying the

dirt from these 20 plus wagons was a big

challenge

with the help of an experiment let's see

how Americans solve this issue

this simple piece solved the big issue

of unloading let's see it in action

I am moving the unloader piece

you can see all the stones are falling

down in this direction this is somewhat

cool

this animation shows the details of the

automated soil dumping machine

when this steam-powered winch rotates it

pulls the unloader towards it as a

result the soil gets dumped from the

open edge of the wagon let's watch the

unloading operation from another angle

these big mountains of dirt on the sides

of the rail track will not allow any

further dumping when the next material

filled wagon arrives

to flatten these mountains the Americans

invented yet another machine the dirt

spreader the dirt spreader has steel

wings that can extend by 11 to 13 feet

from the rails on either side

the operation of this machine is so

satisfying to watch

you can see how effortlessly the machine

pushes away the dirt and flattens the

mountains

once the embankment became wide enough

the clever Engineers shifted the track

to the new flat surface

to shift the track the engineers

invented and deployed another genius

machine called a track shifter the track

shifter has a small but useful crane

powered by a locomotive the workers are

connecting the track with the track

shifter

the first step in the operation is to

lift the track from the ground this is

achieved with the help of a chain yoke

and upper boom Arrangement you might now

be wondering how the steel rails are

able to bend like this this was possible

due to the use of a special kind of

flexible steel rail

now the lower boom turns towards one

side and the track gets shifted this way

a large section of track could be

shifted without having to disassemble

and rebuild the track

if the track shifter had not been

invented it would have taken around 500

workers to toil using the old method

shifting ties and rails separately

by using this newly invented machine

it's estimated that the American

government saved several million dollars

now it's time to see using these

machines how the engineers formed the

Culebra cut the Culebra cut was a big

engineering lesson for civil engineers

worldwide suppose the excavation took

place in a non-mountainous region this

is what the french thought sufficient

enough to dig

however nearly three times more soil

needed to be removed

even the Americans couldn't imagine the

need to remove such a massive amount of

soil

the reason for this is landslides all

the materials have an angle of repose

the angle of repose needed for the

Culebra region was quite low to achieve

a stable cut

after years of Earth removal the

collaber cut was almost ready

the last challenge remaining was this

heightened portion called Gamboa Dyke as

you might expect by now the Americans

tackled this issue in style

on October 10 1913 the American

President Woodrow Wilson pressed a

button which sent a signal to 7 000

kilograms of dynamite located 6 000

kilometers away at Gamboa Dyke in Panama

the engineers had prepared an extensive

electrical cable network mostly under

the ocean to transfer the president's

signal to Panama after pressing the

button the signal took four seconds to

reach its destination

there it caused a spark and a giant

explosion leaving a gap of 60 feet at

Gamboa Dyke the water in the gatun lake

immediately rushed to the calabra cut at

last the Atlantic and Pacific Oceans met

for the first time Not only was this a

moment of great pride for the Americans

but the whole world joined in the

celebration of this historical moment

using the fundamentals and Technologies

we've learned so far let's review all

the details of a ship's Transit across

the Panama Canal

when a cargo ship nears the lock chamber

of the canal the ship propeller must be

turned off

the ship will now be moved by these two

tugboats no ship is allowed to pass

through the lock chamber under its own

power

watch how the ship is perfectly aligned

with the canal gate thanks to the

sideways push of these boats

just before the ship enters the lock

chamber the Canal workers tether it to

four electric locomotives called mules

they travel on either side of a lock

wall on a high voltage rail track these

locomotives carefully guide the ship so

it doesn't hit the lock walls the ship

is now undergoing a few water step climb

operations

the Panama Canal locks are so well

designed that today's enormous ships can

safely travel through it with only

inches to spare

after climbing the final water step

the ship reaches the famous Culebra cut

you know what comes after the caliber

cut the gatun lake

while cruising across the lake

passengers can enjoy Panama's Scenic

Beauty

foreign

once the ship reaches the end of the cut

it's lowered using the reverse water

step method

here's one last fun fact

these Gates you see are called miter

locks and they were originally designed

by the great Leonardo da Vinci around

500 years ago the genius design of the

miter locks form a watertight joint

automatically

mitral locks are huge but you might be

aware that Lasix is in a huge trouble to
