One of the three buried workers ‘ vehicles is believed to have been struck by a rescue pipe being driven through the rubble in an under-construction railroad tunnel, according to firefighters, who hoped to reach the people on Tuesday.
On Monday night, Pak Chong city key Kanatchon Sricharoen reported that a scanner and a sniff dog had found human-like signs, boosting rescue efforts.
Later that night, volunteers discovered essential signs from one resource, but not from the other two locations. They were frantically working against to find a way through the shattered area and approach the victims.
About 1.6 kilometers from the hole access, which is near the Pak Chong district’s Khlong Khanan Chit train station, the fell part begins. The three staff were reportedly entrapped within the tunnel by around 600 meters.
The provincial public relations department said on Tuesday night that the recovery pipe, 1.2 feet in width, hit what was believed to be a vehicle , about 11.30pm on Monday.  ,
To increase the air flow inside the pipe, two more tubes, each about 40 millimeters in size, were being inserted through the larger tube.
As a result of reports from rescue workers that soil and rocks kept falling inside the pipe, firefighters are also strengthening the train’s concrete surfaces to prevent another cave in.
The Sino-Thai high-speed rail, which is being constructed between Bangkok and Nong Khai state, which edges Laos, is comprised of the fell hole.
When a part of the 8-kilometer tunnel collapsed while being constructed in tambon Chan Thuek on Saturday evening, a Taiwanese backhoe driver, a Taiwanese supervisor, and a Myanmar truck driver were trapped in. There were three cars in the pipe- a shovel, a trailer and a vehicle.
Shortly after that, the evacuation procedure began.  ,
