Ask: In Singapore, drain outlets are placed every 5 meters along tarmac roads to ensure rainwater flows off quickly, significantly reducing the risk of sudden flooding. Yes, Singapore’s well-planned drainage system plays a significant role in reducing sudden flooding and preventing water from pooling on roads, which is crucial in avoiding road damage and sinkhole formation. The frequent placement of drain outlets, like every 5 meters, ensures that rainwater is quickly directed away from tarmac surfaces, keeping the roads dry and reducing water-related stress on the road structure. In contrast, places like KL may experience more drainage challenges due to the design and maintenance of the drainage infrastructure. Without a system as thorough as Singapore’s, water can accumulate beneath the surface during heavy rains, contributing to erosion and creating voids that may eventually collapse into sinkholes. The key is proper drainage management, and if KL adopts a similar system to Singapore’s, with consistent drain outlets and good water flow management, tarmac roads could perform much better in minimizing damage. Ultimately, it’s not just the road material but how well the entire drainage and subsurface system is designed and maintained. Singapore’s model is a good example of how effective drainage helps prevent road damage and even sinkholes.
Diana needs a raise for going all the way to the accident site at KL to share this knowledge with us. I wouldn't even dare to go near! Edit: I didn't know my simple comment to praise Diana ignited so many hateful comments. Take a chill pill guys, if you guys wanna go visit the place, go ahead.
Mad kudos to the Talking Point team to have this produced in like what, few weeks??? This and the latest CNA Food Feud series are the only two local programmes I've been watching thus far (considering that I've never watch many local production the past decade).
Mr Goh has maximum Chill - Since there is a chance for people to escape the vehicle if it falls into a sinkhole, there is no need to cordon off this section of the road.
Everything was perfect until the last part when the expert shared about how to get help. Wah piang, if I fall into a sinkhole, I still can stay calm, best part, take out my phone and call for help? WHAT, doing this while balancing on the loose pipes and rocks, with one hand most likely gripping onto the loose rocks. Eh wait, I forgot. Humans are octopus with 8 hands hehe
This news should viral the soonest to notify the public and hopefully engage the Right Professional to look for better solution before the next victim during this unpredictable weather changer. Kuala Lumpur has already started weather changes especially at year end. Be Extra Cautious.
Pretty good except for the slightly ridiculous last part. Sinkholes do not tend to be dry, there’s likely to be flowing water or quicksand/ watery mud underneath based on your own previous experts’ theories - that advice is much more applicable to surviving a building collapse in an earthquake or an avalanche. I think I would be grabbing for a handhold or foothold and try to climb out of there, not stay put. It may collapse even further if you wait and then other things may start falling in.
Any malaysians who is watchng this, please please ask KL governor to engage a university geologist from JAPAN or AMERICA as the geologists are super experience, to at least conduct survey using proper tools like Ground Penetrating Radar (GPR). GPR is a geophysical method that uses radar pulses to image the subsurface! If there is a super big sinkhole beneath KL that is waiting to swallow the highrise buildings there, its going to be end of the world disaster!
Ground Penetrating Radar (GPR) typically penetrates the ground to depths of 1 to 100 feet (about 30 meters), depending on soil composition, moisture levels, and the frequency of the radar used. In areas with dry, sandy soil, it can go deeper, while in denser or wetter ground, penetration may be less effective. For detecting possible sinkholes in a place like KL, where urban infrastructure and soil conditions can vary, GPR can be a useful tool for scanning subsurface anomalies, but its effectiveness also depends on local conditions. 22:27
Ask: Why KL Govt never want to do? Answer: It could be due to a combination of factors. Conducting large-scale GPR surveys requires significant funding, specialized expertise, and coordination, which might not be readily available or prioritized by the KL government. Bureaucratic delays, competing urban projects, and budget constraints could also contribute to their hesitation. Moreover, the authorities may feel that existing geotechnical surveys and studies are sufficient, or they might be unaware of the urgency some people see in potential sinkhole threats. Another possibility is that governments sometimes wait for more concrete signs of danger before acting, although that approach can be risky. Public pressure, like the note you mentioned, might be the push they need to prioritize it. 22:27
@@xcel5203 he was making a point of identifying a possible sinkhole by knocking on the tiles with a hollow sounds feedback. A manhole is a man made structure, that by designed is a hollow structure and not a possible sinkhole. When you are speaking in a position of authority or perceived one, you should refrain from misleading people.
@@ArvinTunas ...he was clearly trying to show what sound it would make if a person were trying to identify a potential sinkhole. Did you actually expect him to hammer on street looking for actual sinkholes while people are walking past? Also that's a utility cover, not a manhole cover. Act smart but only highlight how ignorant you are, clown
KL got more dangerous things than that lah. I was walking down Jalan Pudu, goodness, the five foot way height difference between shophouses is so big you can have a concussion.
“The lady’s body is most likely in one of the pipes and divers are unable to reach her.” OKAY, Let’s call it a day and leave the body there. It’s time for lunch! 😳🤦🏼 So typical of Malaysia.. The least the authorities there could do is to retrieve her body and return it to her love ones. Her son should open a court case and legally SUE the City Of KL!
The lady who fell in was an Indian tourist who was almost 50, not a girl like the ‘eyewitness’ says. She was on her way to a temple on her last day in Malaysia to pray for her and her family’s safe journey home when this happened. Unfortunately, she was right over the part that collapsed and could not grab anything to save herself from falling 8m straight into a broken waste water pipe 1.5m in diameter. People looking into the hole said she clung onto the broken edges of the pipe for a few seconds but could not hold on for long and was swept away. Her being older and wearing a sari did not help matters as the sari material would’ve soaked up the water and gotten very heavy (most sari is 6m-8m of material), dragging her down. The same would happen if you wore jeans, a long dress or multiple layers. Either way, it would’ve been terrifying for her. Such a sad and tragic end to her holiday. RIP.
No fixing. Too much work and money needed. Will only do perfunctory work if disaster strikes to show like we care but dun. After a week called off the sar and just refill the hole with sands and get on with life like things nvr happen. Afterall we need to pray 5 times a day. Friday is practically half day. Aint no time for repair and prevention measures
Perkara paling penting perbaiki pipes dan aliran air.Jika banjir besar berlaku ditempat yang berhampiran .Akan lalu ke kawasan yang lain juga.Berdasarkan pengalaman air perlu mudah lalu jika sangkut-sangkut permukaan tanah akan merekah lama kelamaan jerlus.Kita boleh lihat dikawasan jalan raya sebagai contoh.Ianya berlaku seluruh dunia.Bahan dan cara penyelenggaraan itu penting.
What a reason to be called Sinkies. But just like Florida, it is normal for tropical swampy terrains to form hollow undergrounds due to earth deep underneath being washed away by rainstorms. Even more hard to detect because new big underground hollows can form within a day from normally nothing!
With the increase in underground construction activity the chances of sink holes opening up in new areas have increased. The primary reason though is the nature of the soil whether it's clay,chalk,rock etc and the presence of running water.
This should never happen in Singapore. Hope the govt agencies will be proactive in their inspections. Not only sink holes but pot holes on the road, water logged areas and parasite plants along the road side are good breeding grounds for Mosquitoes.
Nicely done CNA. Always informative and educational.However, nobody asked why a break in the sewer pipe large enough for a person to fall through was not detected? I know it's not a pressurised main but a gravity sewer whereby the loss in pressure or flow is not detectable at the upstream pumping station or visible on the surface. But still, the sewerage company should carry out regular inspections using submersible cameras or sonic detectors to inspect large sewer pipes regularly, especially if its a trunk sewer feeding into a treatment plant as mentioned by a minister. It is clear that the second sink hole is in the line of the sewer pipe. It is also clear from the drone footage that with the area completely tiled, surface water run-off and soak aways were not considered. Most of the rain water probably just seeps into the ground which exasperates the situation. I would like to see an interview where the sewerage company representative is asked why they didn't know that a major asset was defective?
not just one or two in KL... there is many more in somewhere else. pothole might be everywhere, driving on to it felt like exploring on moon and mars. sinkhole another new pothole after this raining season. take care , gangs. many unexpected turns will come we just don't know yet.
This proves that we all are walking on egg shells and are gambing with our life for every step we take! It's the lucky or unlocky draw if we will die today or not! 😮
LTA has some of the most stringent protocols and guidelines for tunnelling activities of any authority in the world. I worked in tunnel construction for 40+ years and on 4 continents. Singaporeans can be assured that LTA has their best interests at the core of their activities.
sudden flashback of the past Nicoll Highway collapse. The COI determined that Nishimatsu, L&M Geotechnic, Monosys and thirteen professionals from the LTA and Nishimatsu were responsible for the collapse.[83][96] Those who received warnings included Nishimatsu personnel, an LTA engineer, soil engineers, and L&M Geotechnic and Monosys, which were engaged in soil analysis.[97] Three others were given counselling by the Manpower Ministry. Nishimatsu and three of its personnel faced criminal charges under the Factories Act. A qualified personn from LTA, who was project director of the CCL and responsible for monitoring the site's readings,[98] faced charges under the Building Control Act.[83][99]
Singapore don't have any news and they need to go around neighboring countries to get some news. Maybe better talk about the high suicide rate in Singapore due to stressful life.
Because there are very little problems to look at in Singapore (too normal and too boring). Malaysia? Tons of newsworthy juice to squeeze. Anwar Ibrahim trying to ban DNS, but got backlash, investments leading to Ghost Cities are one of my favorite to watch. Now potentially a new documentary about sinkholes. Never a dull moment to see what is happening in Malaysia. Let's not forget about them trying to send their troops to help with "Peacekeeping" in Gaza.
Isn't there some sort of ground penetrating radar or ultrasound devices that the govt can use to go around and scan the roads? Why should people just walking go around looking for uneven pavement and carry around a hammer to see if the ground is hollow? 😂
so interlocking pavers is a no no for walkway & roadworks. rain will wash away sand & soil under the pavers. Malaysia many developer using interlocking pavers
The good thing becoming corrupt country like indonesia. We always have fake cheap contruction project every 5 years at least. So accidently there is someone checking every spot of infrastructur for looking how to make money from it. of course this only happen in big city or rich province.
You don't have to pretend as though you are seeing uneven surfaces for the first time in life in Malaysia Diana, please go to the Arab street and Jurong area and you can see plenty of them in Singapore too.
They saw her for a moment after the fall. If you watched more the researcher said the lady still managed to scream for help for a few minutes but was eventually swept away by the current never to be found to this day.
@@GMD3N From the video, it is talking about limestone, reaction to man made atmospheric conditions and interference...pollution,traffic,acid etc which makes it worse As a Malaysian, we need to start thinking deep into how we work intelligently.. the amount of work needed to get up to the stds to meet environmental disasters like this and cash needed to rectify is going to cost a LOT of money... Watch National Geography about Florida,Miami ,Africa and more...climate impact... Hence why insurance cost has shot up recently as claims are going through the roof globally So chill GMD3N...
