Accident Prevention

Excavation accident

Specially, Direct buried method has high

accident risk

Rapid recovery support after disaster

Use of underground facilities information

(excavation accidents, disasters - Earthquake

Tsunami Tornado Hurricane, etc.)

High risk prevention of accidents

Need to adjust NO info. & inaccurate

information of existing underground

facilities

April 28, 1995. Gas explosion in Dae-gu (400 casualties, $ 208 million property loss)

April 11, 1997 Gas explosion in a subway construction site in Gongdeokdong, Seoul

(6 casualties, $ 52 million property loss)

Thousand of accidents including 11 large accidents occurred on across the country

It is required to adopt new systematic and

accurate underground facility management

During a power outage or other construction,

if you do not find the exact electric power pipeline

Tsunami disaster Mar 11, 2011 JAPAN

Helps the reconstruction of

accurate UF information

Needs for maintenance management

Especially its need recovery after disaster

(Earthquake Tsunami Tornado Hurricane, etc.)

The UFS information will become more important

So You need our technology!

1. News reported 160km of underground

facilities in Seoul has lots of difference

between the drawing information and

the actual location

2. Maintain & Manage the latest

Detecting

method

Electro

magnetic

Induction

Method

Principal of detecting

Detection by receiving a

generated signal by forming

the current magnetic field on

the buried conducts.

Weak point

▶ Detectable only when the electric current is possible to flow

▶ Difficult to detect the objects in the areas electromagnetic

such as the high voltage

Ground

Penetration

Radar

Receiving the reflected signal

by firing

the electric wave to the

underground

▶ Since the underground is much more irregular than the air various

and raise a lot of noise, it is very difficult to measure.

Acoustic

Location

Method

Detecting the water waves

generated in the water pipe by

sending a water wave

signal to the water flowing

▶ Possible to use only when water flows

▶ Possible to detect only when the pipe is filled with water

Electro

magnetic

Coil Method

Detect the electromagnetic

waves with the Transceiver

▶Electromagnetic waves are far influenced by external

environment such as scattering, error occurrence

12

Comparison with similar technology of World

Detecting

methodPrincipal of detecting Weak point

Warning

Magnetic

Tape

Method

indicating cover tape and

detect by installing the

magnetic material between

the folds

▶ Low depth of detecting

▶ No way to measure the depth

▶ Possibility of detection error caused by surrounding

magnetic field.

UFMS

Magnetic

Markers

1. Detect magnetic

markers by using Magnetic

detector

2. Construction of New

UFMS for maintenance

management

▶ Possible to accurate survey regardless of material

▶ Not affected by the surrounding environment such as

high-voltage lines and communication lines, etc,.

▶ Possible to adapt and detect all kinds of pipes

regardless of the pipe material

13

Detecting

methodPrincipal of detecting Advantage

Comparison with similar technology of World

• We can detect only the magnetic fields of magnetic markers because protective plate is not

magnetized by the magnetic markers. And accurately find out the depth and location of

underground gas pipes

Measurement in the right

side part of protection steel

plate

Measurement in the right side

part of the plate, magnetic

marker to detect numerical

response to -66

Measurement in the central

part of protection steel plate

Magnetic marker to detect

numerical response to +99

Measurement in the left side part

of protection steel plate

Magnetic marker to detect

numerical response to -72

14

Attached on top of various underground facilities,

Magnetic Markers form magnetic arrays and they

inform their location to the magnetic detector so that they can play a

role as the indicator (sensor)

accurately tracking the location of facilities.
