The office tell (a kind of one-room) of Kasamagong Ward in Seoul,
the ground of the construction site collapses and the inhabitants
of the apartment evacuate
One week after the uproar came,
One week after the uproar came,
At the after time the multi-family housing construction site was
near kindergarten of the Supyeong-dong district (Tongjakg-sandong) collapsed.
Both cases are caused by the collapse of the sheet pile at the construction site.
In the overall construction process the piling work is the most likely accident.
It's because safety and cost are part of the front.
In order to deal with soils that human beings can not anticipate,
In the overall construction process the piling work is the most likely accident.
It's because safety and cost are part of the front.
In order to deal with soils that human beings can not anticipate,
it is necessary to secure the highest degree of safety,
but since the sheet piles are temporary structures that are no longer necessary
after the completion of this building, the main object of cost reduction It is also.
The pile-related accident continues between this contradiction.
The pile-related accident continues between this contradiction.
Assembling a temporary structure for construction such as a mold, bundle pole,
scaffolding, pile sheet etc. is called temporary construction.
According to the statistics, of the 3434 deaths of the entire construction industry
According to the statistics, of the 3434 deaths of the entire construction industry
in the decade before 2011, the temporary construction related
is 484,1647 people.
In order to secure profits without touching direct expenses
In order to secure profits without touching direct expenses
with the construction ordered by low price bidding,
it is nothing other than to reduce overhead like temporary construction.
In particular, Sheet pile is the same as chicken stock.
It is regrettable to throw away the chicken stock,
but it is satisfying So that do not have a meat ,
Sheet pile is that it is a waste to make it somewhat costly
to put emphasis on safety.
In the majority of cases,
In the majority of cases,
it can not be freed from the temptation
to make this structure before the soil "transforms".
Soil has an intermediate property between liquid and solid.
The solids can be stacked vertically, the liquid spreads horizontally,
The solids can be stacked vertically, the liquid spreads horizontally,
but the soil creates an inclined plane that is intermediate there.
The shape of the surrounding mountains is all this.
The shape of the surrounding mountains is all this.
This force trying to make an inclined surface makes earth pressure
and knocks down the sheet pile.
In addition, the soil is made up of mineral, water, air,
In addition, the soil is made up of mineral, water, air,
pores (gaps between soil particles) and so on, so it compresses like a sponge.
Italian "Leaning Tower of Pisa" is a case
Italian "Leaning Tower of Pisa" is a case
where one of the grounds is pressed and tilted.
Once you have a waterway in the pore of the soil,
it will lead to a major catastrophe like
the collapse of the dam of Laos occurred in July this year.
When the 1990 flood occurred, the embankment of the Han River (Hangan)
near Goyang City (Gyeonggi Province, Gyeonggi)
in Gyeonggi Province collapsed also occurred when water flowed
into the hole dug by the mice.
This phenomenon is called scouring.
This phenomenon is called scouring.
All the sink halls due to subway work and rupture of water supply
and sewer pipes are all caused by this phenomenon.
In order to handle unpredictable soil,
In order to handle unpredictable soil,
it is necessary to place a higher safety valve than this structure,
but there is a problem in reality that is not the case.
However, while watching this accident, I caught my mind about the disaster
of the Vajont dam which occurred in Italy in 1963.
The accident at the time when 5000 people passed away was to be included
The accident at the time when 5000 people passed away was to be included
in "5 lessons learned and 5 good news" set by the United Nations Educational,
Scientific and Cultural Organization (UNESCO) in 2008
"International Year of Planet Earth".
Waves of 250 meters high crossed the dam and swallowed five villages
Waves of 250 meters high crossed the dam and swallowed five villages
in only six minutes.
The cause of this "mega tsunami" was a landslide.
Sand and rock of 260 million cubic meters from the mountain next
The cause of this "mega tsunami" was a landslide.
Sand and rock of 260 million cubic meters from the mountain next
to the dam collapsed at a speed of 110 km / h and pushed out the dam water.
In the electric company SADE, in addition to the fact that the geological features
of the dam candidate site are limestone and clay layers weak in water,
in addition to ignoring the opinion that the construction of the dam is inappropriate due
to the inclination, forced construction.
Tilt the hamburger containing slippery cheese.
One month before the accident 25 cm a day the ground was moving

One month before the accident 25 cm a day the ground was moving
the evacuation order was not issued.
This shock wave energy was twice the size of the Hiroshima atomic bomb,
This shock wave energy was twice the size of the Hiroshima atomic bomb,
so it seems like we did an atomic bomb experiment
without evacuating the residents.
Samdong-dong kindergarten has already diagnosed experts that
the gneiss fault is inclined five months ago and there is a danger of collapse.
The fact that the building was tilted the previous day
The fact that the building was tilted the previous day
was also reported to the Cool Spring Ward Office.
Structures are also trying to prevent themselves
Structures are also trying to prevent themselves
from collapsing through deformation and cracks.
It is not about yesterday and today
It is not about yesterday and today
that they tried to neglect such advance warning.
In 1994, the day before the collapse of the Holy Water (Son) Ohashi,
the citizen's appeal that the gaps are spreading
has Seoul City government officials anyway have a thick skin.
1995 The collapse of the department store of Sanfeng (samen) in the morning,
1995 The collapse of the department store of Sanfeng (samen) in the morning,
water leaked from the building and continued to operate despite the sound,
after all, 502 people (except for 6 missing persons) died.
Interpreting a precursor of collapse as convenient
for them is due to a confirmation bias that
They want to believe that there is no way it can collapse.
In the background there is a hidden rational division
In the background there is a hidden rational division
on the utility obtained by floating safety costs.
Even if you condemn such attitude as a pathological condition like
Even if you condemn such attitude as a pathological condition like
"Safety insensitivity" the problem will not be resolved unnoticed.
There is only one way for safety it is pay appropriate costs.
Korea's construction cost per square meter is 1.63 million won
(about 1,447.85 US dollars), which is the 26th largest country in 62 countries.
It is 2.8 times smaller than the UK in 1st place.
It is 2.8 times smaller than the UK in 1st place.
The fact that Korea is the most dominant world in the world
and the 26.3 times that of the UK is related
to this is the industrial accident mortality rate reflecting the income level.
Construction industrial accident is 51.5% of the total.
While becoming the world's ten largest economy,
Construction sites are still "cheap and fast"

logic dominates the development era.

It is the same reason why the dam of Laos is destroyed.
Priority is given to short-term interests,
