Phraya Banlue canal road subsides in Ayutthaya



AYUTTHAYA: -- Another heavy land subsidence was reported today at a road beside Klong Phraya Banlue canal in Lat Bualuang district of Ayutthaya, forcing local authorities to seal the road to traffic for safety.

The road subsided for several sections which measured almost two metres from the surface and almost 100 metre long in each section.

The serious subsidence was reported on the canal road from which runs parallel to the Phraya Banlue canal in Tambon Sammuang from in front of Nurund Hidaya Mosque (Surao Mai).

Another section also subsided over two metres deep and eight metres wide, covering the entire two-lane traffic of the canal road.

It was fortunate that no people was injured as the subsidence occurred at night and no vehicle passed the road last night.

Ayutthaya authorities ordered the closure of the road along the canal for safety reason.

Rural highway authorities said it could take up to two weeks to repair the subsided road and open to traffic again.

The land subsidence was blamed on the receding water in the canal which runs dry because of drought, and pumping of water out of the canal for farming by farmers.

Earlier yesterday the sharp drop of the water level in Klong Rapeepat in Saraburi’s Nong Sua district has caused the heavy subsidence of a section of the road beside the canal resulting to a closure of the road to traffic.

The land subsidence occurred to the road from Nong Kae to a police booth at Pak Tho covering a distance of about 150 metres. The road subsided by 1-2 metres from its former level prompting the Saraburi highway office to block the affected stretch to all traffic with barriers.

Officials said that the land subsidence occurred before on this road but the problem this year is much worse. It was however lucky that no motorists were harmed as the problem was detected in advance.

Road collapses reported in many drought-hit provinces

BANGKOK, 6 July 2015 (NNT) - The drought crisis has been blamed for major road collapses in Ayutthaya, Pathum Thani and other provinces. No one was killed or injured by the incidents.

Sections of up to 88 roads in Pathum Thani collapsed after canals in many areas dried up. Roads in Nong Suer and Klong Luang districts sustained the most damage, as canals run alongside most roads. Motorists are urged to avoid these roads and exercise caution while driving. The Disaster Prevention and Mitigation unit has carried out repair work on 27 roads, and additional funds are being approved to re-open more roads for traffic.

In Ayutthaya, the drought caused water levels in canals around the province to hit record lows, resulting in road collapses. Late on Monday night, the road built along Praya Bunlue Canal collapsed further. The subsidence is over two meters deep and 100 meters long, rendering the road inaccessible for motor vehicles. The collapse followed another major road subsidence nearby, where the crack is almost three meters deep. The cracks are expected to grow without immediate repair.

The sharp drop of the water level in Rapeepat canal in Saraburi’s Nong Sua district has also caused heavy subsidence of a section of road beside the canal, resulting in the closure of the road to traffic.

Question to our qualified / experienced civil engineers:

Is this just bound to happen and cannot be prevented, or.....?

[Reigntax]

Scorecard,

No, no bound to happen and yes, can be prevented.

It is only a small section of the whole road which from the pic also runs its full length alongside the canal.

If unpreventable you would expect some movement to have occurred at other locations as well.

Changes in moisture content of soil can cause issues, especially clay based soils that expand and contract more than sand based soils.

In this case, there may have been a localised abnormality not known about during construction but the more likely cause is either 'one size fits all' engineering or a local land owner is disposing of some type of waste water under the road and the pipes have failed or similar.

It is hard to see from the picture but the soil directly under the road base seems nothing more than dirt and reddish clay both which would be considered an inadequate road base material.

[BigBadGeordie]

And yet the plan is to dig/drill 1000 more wells to extract more groundwater??

You gotta love TV there is an expert ready for comment on any subject.

[lostmebike]

forcing local authorities to seal the road to traffic for safety.

I`m sure Somchai can still get along there in his `I-slow-zu`

[Equalizer]

You do not actually need to be an engineer to know that roads are built on crushed rock that vary in size from large to small, the smallest being at the top for base tarmac to sit on. You cannot tarmac over sand and clay for goodness sake.

[realenglish1]

So the road are now protesting Can you arrest a road

I need to think about that one

[kannot]

How would I know there was a problem without the twig in it??? Looks like a normal Thai road to me

[LawrenceN]

Have to love Thai engineers

Yes, either love them or prosecute them for negligence.

[kannot]

Im surprised the tarmac is more than a quarter of an inch thick as thats all it is on our "road"

Amazing how the Romans could do it

[fareastguy]

Subsidence due to drought or piss-poor highway construction ??

[gerry123]

it could take up to two weeks to repair the subsided road!!! Wow that's about a week longer than it took to construct

put together the first/second /third time round

[hutchings1963]

I WONDER HOW MANY FINGERS WERE IN THE PIE WHEN THEY BUILT THIS ROAD,WAS A PROPER SURVEY DONE ON THE ROAD WHEN IT WAS BUILT EASY YOU HAVE 10 SECONDS TO ANSWER,ANSWERS PLEASE ON A POSTCARD TO GOVERMENT HOUSE WHERE THERE THE IDIOTS MEET EVERY DAY.

Have a look at my post #3835 here on TVF ; I had nearly the same answer ( 4 centimeters ) as you did here ...

How many fingers were in the pie when they built Highway117 from Nakhon Sawan to Phitsanulok? It's a disgrace.

[wvavin]

Anywhere else in Thailand is still safe?

Thai what ?

Engineers, like Casey Jones, he was an engineer and we all know how safe Thai trains...........ah..........well moving on swiftly.

[Assurancetourix]

Engineers ??!

I'm looking after this word in my thai encyclopedic dictionary ( 32 volumes ) but cannot find it ;

Is it normal Dr Watson ?

[jackanapes]

typical thai response its the drought that's causing the roads to subside under normal conditions this shouldn't happen theres more to this issue than drought conditions .

[dotpoom]

" forcing local authorities to seal the road to traffic for safety."

Oh...I suppose it would have been possible to carry on using it if only we weren't so concerned about the safety factor?

I didn't knew about John Luther (Casey) Jones ;

but now , thanks to you,

You are correct, fact is there are many experts on a wide range of subjects here, trouble is there are too many who's only expertise is bitching and moaning.

Ever seen a Roman road, ever examined the grading of stone used in its construction ? Such road building techniques have been the blue-print for road building around the world up to the 21st century, but it seems Thailand chose to ignore 2000 years or wisdom.

Yes, of course you are quite correct about TVs experts. Most of the long-stay farangs are retired after a lifetime of work, so of course they have good knowledge in particular areas. There is a depth of farang talent that you and Thailand ingeneral seems to either ignore or ridicule.
