After Sichuan wenchuan earthquake, 187 people in the China National
Earthquake Disaster Emergency Rescue Team arrived at the disaster area,
and also fighted in Dujiangyan, Mianzhu, Wenchuan and Beichuan
with modern equipment and first-class rescue technology, saving life from the ruins.
Professional rescue personnel are equipped with all kinds of advanced
detection instruments and cutting and supporting equipment.
The sensitivity of the instrument is very high, so as long as the survivor
makes a small sound, the sonic detector can detect it. So even the person
who is buried in the rubble is unable to speak, the sound detector
is able to capture it in time even just tapping his fingers
and making a faint sound.
Infrared detectors make the best use of infrared reflections.
In the dark, it can detect the presence of life in an accident
according to temperature.
Opitcal detectors are also known as"snake eyes", which use light
reflection to detect life. In front of the instrument has a tiny probe,
which can go into tiny crack to detect. Rescuers put the probe into
the places needed to be detected, then the probe can rotate 360º
so rescuers can use viewer to see the places clearly that the probe detects.
The dog's sensitive sense of smell can give play to some abilities
that some advanced instruments do not have and the rescue range
can reach 2000 ~ 3000 square meters and 3 meters underground,
which make rescuers find viable lives in the rubble more quickly
and accurately. Experience shows that if use artificial search,
it takes 30 ~ 60 minutes to complete a local search, but if use dogs,
just 5 ~ 10 minutes. In a certain place, if rescuers can’t find
survivors using two sniffer dogs consecutively, then the place
can almost be thought that there are no survivors.
In addition, there are hydraulic tongs, high-pressure lifting
support air cushion, the moon light and other advanced equipment
that are used to cut, support and light. This equipment
can be used to protect rescuers to remove or support the object
on the top of the survivors’ body, winning precious time for life.
In order to ensure the smooth communication, the rescue teams
are equipped with satellite telephone, walkie-talkie and other
communication tools to ensure the smooth communication of
information in the rescue.
Due to the limitations of existing scientific and technological means,
it is still difficult to get accurate prediction for most earthquakes.
Therefore, it is necessary to strengthen the relief work after the earthquake.
Take Wenchuan earthquake as the research background, from
the perspective of the affected people, the evaluation
index system of earthquake emergency capability of local
government is put forward , and the method of interview
and field survey to collect data to evaluate government
emergency response capability of five worst-hit areas in
Whenchuan earthquake is adopted. The theory of mirror
government ability and modern organization theory proposed
that the government emergency ability includes static and
dynamic ability, of which that the static ability is the
basic emergency ability, and the dynamic ability contains
information gathering force, emergency rescue capabilities,
ability of resource integration, ability to maintain stability
and aftermath processing ability.
