The Rama III Road footpath that collapsed on Monday was probably a combination of two factors: the collapse of a soil-holding wall and water erosion.
The section of footpath that collapsed was almost three metres in depth, five metres in width and 22metres long and stretches from Soi 21 to 23 in Bang Kho Laem district.
The City’s deputy governor, Theerachon Manomaipibul, who inspected the site this morning, said an initial inspection had revealed that the subsidence resulted from the collapse of soil holding wall combined with water erosion, as the site was next to the Bang Khlo Drainage Canal.
He said the footpath in the area had been constantly improved and had thus been subject to weight pressures, which affected the soilholding wall.
Theerachon said officials would first retrieve the materials that had fallen into the roadside canal. The Engineering Institute of Thailand and related agencies had been contacted to inspect the subsidence and would jointly redesign the infrastructure.
Meanwhile, the Engineering Institute of Thailand will on Wednesday morning announce the result of the investigation into the sinkhole that appeared on March 18 on Rama IV Road.
The institute’s secretary general Thanes Veerasiri said that early findings indicated that the sinkhole resulted from water that had originally leaked into an underground void then run out, leaving a big hole underground.
