SinkTree System is how to handle “sinkhole” occurrence

Leak occurred by aged and corroded facility creates sinkhole.
SinkTree System detect cavity formed by leak immediately and alert admin.

SinkTree System

Sinkhole occurrence is increasing due to soil inflow from aging and corroding pipeline. Considering the tendency and relation of increasing urban underground development and aging pipelines, technology to counterpart those problems is necessary on a national level. Especially pipe connections leak is the biggest cause of sinkhole so technology to detect is a must.

This System detect small cavity form from leak by installing Sinkball on top of pipe connections and prevent sinkhole by sending real-time alert to the admin.

Components

Sinkball

Detect cavity formed from pipe connection leak.

Detector

Deliver cavity detection information to the server and the admin.

Q & A

Q

What is UNDERCITY SOLUTION?


A

All buried underground pipe such as water and sewer pipe, gas pipe, communication pipe, electricity pipe, heating pipe, oil pipe, agricultural pipe, and etc make our lives convenient. But it is difficult to manage because it is buried and unseen. UNDERCITY SOLUTION is a system to prevent damage from other excavation work and detect leak in real-time. It can be classified with Smart Pipeline Monitoring System and SinkTree System.


Q

What is SinkTree System?


A

85% of ground subsidence occurring currently is from drain pipe damage. This system detects and locates ground subsidence due to drain pipe connection differential settlement or damage at the initial stage. It can be constructed with small amount of budget.


Q

What do you use to power the Detector?


A

Detector can operate by general electricity or power generated by sunlight. It is more efficient to use sunlight because it will operate by low electricity.


Q

Don’t you have to frequently visit site to check remaining battery?


A

There is no need to visit site to check remaining battery. It can be checked online in real-time. Furthermore, it is designed to operate for 15 days (give or take) even during raining or snowing season when it is difficult to charge battery.


Q

Can the facility be monitored as one facility even when various types of pipe are used?


A

It is our advantage that the system is designed to be efficiently manage as one facility network even when various types and sizes of pipe are used.


Q

Isn’t it hard to repair the sensing line?


A

What we send from Detector is signal. There is no risk for electric shock. Just cut off damaged sensing line with scissor and just reconnect with connecting jack and attach Protection Cover to protect the line from water inflow. Lastly, attach 10cm width butyl attached plate of glass fiber sheet.


Q

Through what route does Admin and Excavation worker receive alarm?


A

Our system collect database to detect leak around pipe connections (Sensing line length from Detector, GIS, Details of facility, etc). At this time, Admin’s phone will be updated to the server. If sensing line is cut or leak detection sensor operates, it compares with collected database for accurate location and alert the admin in real-time. Excavation worker’s contact can be listed to the server before construction or they can download our app on their phone to receive real-time alert.


Q

According to Underground Safety Act, it must check ground subsidence with GPR device in every 5 years. Can we do that with your system?


A

The range of GPR machine to check ground subsidence underground is down to 2 meters. Using sensing line inserted in Smart Prevention Sheet can detect down to 10 meters underground. We are fully aware of laying depth of Smart Prevention Sheet during construction and by comparing depth of Smart Prevention Sheet laid in the same area, 1 year later, is how we check its ground subsidence.
