Completed repair of subsidence hole on the road to Sin Cheng commune

After nearly 4 days of construction, by early afternoon of August 10, the subsidence point on the road from National Highway 4 to the center of Sin Cheng commune (Si Ma Cai district, Lao Cai) had been fixed, and traffic returned to normal.

As reported, at around 9am on August 7, on the road section passing through Mao Sao Chai village (connecting National Highway 4 with Sin Cheng commune), a sinkhole appeared with a circumference of about 16m, 6m deep, and the volume of collapsed rock and soil was estimated at about 100m³.

Immediately after receiving the news, the People's Committee of Sin Cheng commune coordinated with the commune police to put up warning ropes, put up traffic signs, and at the same time organized a survey to develop a solution.

Repair work is carried out carefully to ensure safety for people and construction vehicles.

The remedial works encountered many difficulties. Due to the deep hole and complex geology, the construction units had to do it manually, using layered stone cages for reinforcement, and machines only supported the external leveling.

Nearly 60m3 of rubble was used to fill the sinkhole.

To fill the hole, the commune government used 30 iron baskets containing nearly 60m³ of rubble (linked together) to drop into the bottom of the hole to create an anti-collapse foundation, then poured 20m³ of crushed stone to fill the gap and level the ground to ensure the temporary tightness of the roadbed.

Mr. Vien Dinh Hiep, Chairman of the People's Committee of Sin Cheng Commune, said that by early this afternoon (August 10), the work to fix the sinkhole had basically been completed to open the first phase of the traffic route, motorbikes and cars could now pass normally.

Although the road has been cleared, we are still monitoring the stability of the sinkhole. Vehicles and people passing through here need to pay attention to prevent sudden sinkholes that cause traffic safety problems.

Mr. Vien Dinh Hiep, Chairman of Sin Cheng Commune People's Committee

The repair of the subsidence hole on the road to Sin Cheng commune has been completed to serve traffic.

Due to the special geological structure, Sin Cheng commune and the communes of the old Si Ma Cai district often have sinkholes related to underground caster caves, especially during periods of prolonged heavy rain. Therefore, people need to be vigilant to ensure safety.
