Subsidence occurs every day on a large scale
As the Economic and Urban newspaper reported, right before the 2024 Lunar New Year, landslides and subsidence in Tran Van Thoi district began to occur with increasingly complicated developments. In the early days of March 2024, nearly 100 subsidence and landslides continuously occurred with a total length of thousands of meters, causing great damage to State property and greatly affecting the travel of people across the country. locality.
Talking to reporters, Mr. Kieu Minh Tieng, Vice Chairman of the District People's Committee Tran Van Thoi, said that as of this morning, March 7, 2024, landslides and subsidence have occurred in 9 communes and towns in the freshwater region. , a total of 128 routes, with 482 locations, with a total length of 12,590m, of which: 9,166m long concrete road (1.5m concrete road 5,033m long, 2.0m concrete road 124m long, concrete road 2.5m long, 86m long, 3.0m concrete road, 3,923m long), black dirt road 3,429m long; Estimated damage is about 16,800 million VND. “On March 6, 2024 alone, new subsidence occurred in 07 routes in 22 locations, 569m in length, including 554m of concrete road (1.5m concrete road, 319m long; 3.0m, 235m long), black dirt road 15m long" - Mr. Kieu Minh Tieng added.
According to the authorities, due to drought, rapid water evaporation, combined with pumping water for production, has caused most of the canals and ditches in the freshwater region to dry up. Meanwhile, the height of the bottom of the canal is deep, the height difference between the road surface and the current water level is very large, causing loss of counterpressure causing subsidence; At the same time, the air circulation space (width of river banks, canals, canals) from the edge of the road surface to the edge of the narrow canal.
This is the main cause of subsidence and landslides, damaging many rural roads in communes and towns in the freshwater region. In addition, there are other reasons such as: weak geological characteristics, deep canal bed,... causing landslides and subsidence.
Proactive solutions to overcome
Faced with the above situation, local authorities and people at all levels have proactively taken many solutions to overcome it in order to minimize the landslides and subsidence that may occur next.
Militia and self-defense forces, commune, hamlet and hamlet officials closely accompany people in taking measures to reduce the load on the ground, especially on roads with dry river beds and high risk of subsidence. People cut trees, prune branches, people make fences,... the atmosphere takes place busily on many roads.
On the other hand, increase patrols, check vehicle loads, install signs, barriers, appropriately reduce traffic on roads managed by districts and communes, etc. to ensure traffic safety.
When an incident occurs, officers immediately go to the scene to check; Installing ropes, making fences, warning signs to limit traffic, temporarily reinforcing with local wood trees the road sections with landslides and small land subsidence. Regularly propagate and mobilize people on the embankment, reinforce and prevent landslides and subsidence in sections with high risk of landslides and subsidence.
According to the People's Committee of Tran Van Thoi district, as of the morning of March 7, in the communes and towns of the freshwater region, 55 temporary tree embankments with a total length of 1,340m have been repaired. More than 135 tree routes have been cut and pruned, 1,700 trees have been cut, and more than 1,250 trees have been pruned (including coconut trees, eucalyptus trees, bamboo trees, and other large canopy trees...etc.).
In addition, propaganda has mobilized people in more than 50 cases of heavy construction material dumps along rivers, canals and ditches to move away from locations at risk of subsidence and landslides; For houses along rivers, canals, and canals, warning notices have been sent to people to move assets and heavy objects out of areas with high risk of subsidence and landslides in more than 450 cases. Install more than 260 warning signs, barriers, ropes, and traffic restriction warning signs at subsidence points; Replace the boards to reduce the load of routes for management.
Mr. Le Chien Luy, Vice Chairman of Tran Hoi Commune People's Committee, said: "Immediately after the phenomenon of subsidence and landslides began to appear in the area, the commune mobilized the commune, militia and self-defense forces, and the youth union. Commune, hamlet officials and mobilize people to jointly carry out the work of overcoming subsidence points; At the same time, troops are pruning trees and reducing the load on roads at risk of subsidence."
“We must ensure the safety of roads for people to travel. In the difficulty caused by this natural disaster, it also shows the consensus from officials to the people, with some households even volunteering to help their brothers eat and drink while on duty" - Mr. Nguyen Chi Tam, Secretary of the Commune Party Committee Khanh Hai shared.
Farmers have to transport rice by two-wheeled vehicles
Subsidence and landslides causing damage to traffic routes occur at the time people harvest winter-spring rice. This has caused people to have to increase costs when they have to hire two-wheeled vehicles to transport rice to purchasing points on the main route (Tac Thu - Rach Rang - Song Doc; Tac Thu - Co Xang - Vam Da Silver). It is estimated that people have to pay 250,000 VND - 450,000 VND for the transportation cost of each ton of rice.
As of March 6, 23,460/28,954 hectares have been harvested, reaching 81.02% of the sowing area; Estimated yield is 6.4 tons/ha, total output is 150,904 tons. According to statistics from communes and towns, rice output has so far been sold 130,838 tons. Rice varieties ST24, ST25, Loc Troi 28 sell at 8,000 - 8,200 VND/kg, up 600 - 800 VND/kg over the same period; Rice varieties OM5451, OM18,... selling price is 7,200 - 7,400 VND/kg, equivalent to the same period.
A road has sunk and cannot be passed through, the commune's militia force has to be on duty, setting up ropes to warn people.
