Klong 13 canal road subsided



BANGKOK: -- Klong 13 canal road linking Lamlooka and Rangsit Ongkharak roads in Bangkok's eastern suburb suffered second major subsidence when over 100 metres long section of this asphalt rural road sank up to five metres below normal surface.

Fortunately no motorists were injured when the road which runs parallel to the Klong 13 Irrigation canal subsided.

Thanyaburi district officials and workers from the Department of Rural Roads are now inspecting the rural road and were repairing it back to normal.

Presently traffic was sealed off and the road was declared dangerous for motorists to pass.

Thanyaburi officials said the rural road began to show cracks at several sections after water in the canal receded quickly following the drought.

At end of last year, over 500 metres section of the road also sank four metres from ground level as the area suffered acute water shortage.

They usually blame the rain

They usually blame the rain

They will again, there's not enough of it ...

Well it has been proven that Bkk is sinking.

How about poor construction to blame?

Maybe when they will stop to build roads on sand and dust ...we can continue to dream

I bet that is all fill dirt, not compacted well enough.

where is the road base, all they have done is rolled the dirt/sand and layed the bitumen over the top, no wonder it has collapsed. This is the problem with all the thai roads, they do not use the proper sub structures before laying the surface material, they allow for it to be done properly but by the time everyone takes their cut they can only do a half ar*ed job so the roads break up/collapse. This will not stop happening until the corrupt practices by those in charge stop, they need to have responsibility all the way down and sampling/inspections done and passed on the construction process and payment only given when the work is passed as being correct.

Oh dear then because they are repairing it back to normal, some high ranking official may have given a friend a permanent contract

Thainess

They will always make sure they find somebody else to blame

Even with simple things like drive in to houses they cant seem to get it right. They will not accept that you can not pour new concrete next to existing and it will remain together.

Not just the roads.

Your right. The roads around our condo had a veneer of cement on top and when that wore off it exposed large stones and wire mesh. Nothing will be done however.

repairing it back to normal. Few loads of rubble and hard-core then a wafer thin layer of asphalt and thats it back to normal until next year then it can be repaired again as normal.

It looks like a concrete road, and anyway, no normal base prevents 5m of rapid subsidence, this is the result of large amounts of underground water moving, there needs to be an appropriate system in place to allow that water to move without it taking earth with it.

'...this is the result of large amounts of underground water moving...'

Which, of course, makes perfect sense.

Large amounts of underground water during the worst drought in, what was the figure? 20 years?

With all the large amounts of underground water rushing everywhere, expect more 'close to canal' collapses.

The make work projects continue. Don't build it right, don't repair it right, work forever.

I thought it was just the people, but even the roads here aren't ready for modern motorized vehicles.

Yes, it does make sense, the canal leaking into the ground water under the road, the drought causing the water table to drop, lowering the canal and causing the water that was saturating the soil under the road to leave, this large amount of water moving taking with it the soil from under the road. And yes, expect more subsidence if the drought continues, subsidence is largely a dry weather phenomenon as saturated clay shrinks when drying but this is more than that, this is 5m of movement, that can only occur by water having washed away the soil.

That whole area is normally under water. Basically all the land in and around Bangkok is a flood area. Always surprises me they can put up factories, etc, in an area like this.

I passed by that area the other day and on the highway there were water sprinklers watering the grass of the roadside sidewalks. As drought-conscious Thailand urge water conservation during a record dry year, sprinklers like these can offer an all-too-visible waste that sends gallons of water down the drain or evaporating into thin air. Pumping canal water out to water the grass! Great Idea!
