More than 100 billion landslide projects

After substantial discovery, the Ma riverbank near Ham Rong District in Ham Rong District was eroded by over 60 meters of bank. Landslides are threatening the safety of the dam.

The investment project for emergency work on the Ma riverbank has been seriously deteriorated.

The investment project for emergency work on the Ma riverbank has been seriously deteriorated.

The lowering of the level of this dam is known to have occurred for many years. But landslides in this area are even worse.

In the field, over 60m of reinforced concrete levees were degenerated, and the total levees in the levees were about 2m below their original locations. Many stone pavement slabs spread, large concrete beams break, and the embankment structure changes.

This is the embankment of the project that invests in the construction of emergency operations for the discharge of Ma River. Prior to this situation, the local authorities sent a warning sign to stop the sinking area.

Many slabs on the dyke became flat.

The Ministry of Agriculture and Rural Development of Thanh Hoa province also carried out inspections. As a result of the test, the embankment appeared as a landslide and sedimentation corresponds to K39 + 484 – K39 + 534.

Falling depth of 0.2 – 2 m; Ma The nearest slope of the river bank is 3.9 m. The base of the embankment is 1 – 2 m in length and 27 m in length.

According to the functional sector, the cause is due to the impact of the floods in 2017 and 2018. The landslide phenomenon continues and becomes serious.

The surface of the bank has sunk about 2m below the original site.

The Department of Agriculture and Rural Development has set up a fence at the Ham Rong Ward People's Committee in Thanh Hoa City, asking them to set up fences, signage, and tell the public about dangerous areas.

At the same time, people and ships are prohibited from accessing landslide areas. The dike management unit can closely monitor the evolving of the development of sedimentation, preparation materials, human resources and means to deal with bad situation, continue monitoring.

It was known to be about 1.4 km long and the embankment of the emergency treatment project of the Ma River Bank until the Tran Hung Dao intersection, Ham Rong ward, Thanh Hoa at Ham Rong Bridge.

In the survey, the footprint of K39 + 364.5-K39 + 418.05 was reinforced with two rows of reinforced concrete piles of length 6m, but when designing the construction drawings, flood protection with Thuy and Thanh Hoa's consultants removed the files, Not provided.

With regard to the above-mentioned issues, the Thanh Hoa provincial people's committee called for clarification and treatment of the organizations and individuals who committed the violation.

Currently, the management department is the dike and flood control department. Thanh Hoa continues to investigate to coordinate this work and suggest directions for repair.

Large concrete beams are also damaged to change the embankment structure.
