The canal section in Thanh Da peninsula is sinking 2 cm per day.

Ho Chi Minh City: Nearly 200 meters of Thanh Da canal bank, Binh Thanh district, continues to sink nearly 2 cm per day after the embankment collapsed, directly affecting 13 households living above.

The information has just been released by the HCM City Department of Transport after 9 days of monitoring and measuring by the Port Design and Marine Engineering Joint Stock Company (consultant). The results show that the nearly 200 m long Thanh Da canal bank is sinking vertically at an average of 1.78 cm per day and horizontally, sliding towards the canal bed about 2 cm. It is forecasted that this situation will continue, posing a risk of landslides affecting the constructions and houses built above.

Nearly a month ago, this section of the canal bank collapsed, damaging about 120 meters of embankment. Many houses above the canal sank and cracked, some of which leaned toward the canal. The city then had to urgently evacuate 13 households and warned that the area at risk of landslides should be restricted for safety.

To accurately assess the cause and solution, the consulting unit proposed a general survey and collection of additional data on topography, geology, hydrology, etc. However, the immediate measure is to lower the load of some houses near the top of the embankment to reduce the impact on the canal bank, temporarily ensuring the safety of the people. This was agreed upon by a number of related units.

According to Deputy Director of the HCM City Department of Transport Bui Hoa An, the Thanh Da embankment was completed in 2009. At that time, the residential buildings above had not been built yet and the safety corridor was 10 meters. Up to now, houses have been built about 3.5 meters from the top of the embankment, leading to a large load above.

The Department has assigned the Waterway Management Center to provide documents related to the construction of the above embankment section to the consulting unit for research, assessment of specific causes and proposed solutions. The relevant units will also coordinate with local authorities to closely monitor and ensure safety for the people.

In addition, this agency requested Binh Thanh district to compile legal documents of houses, land, assets... of affected households to prepare for site clearance for embankment reinforcement after finding a solution.

In addition to the above area, at Thanh Da peninsula, construction projects to build embankments to prevent landslides in many other sections are also being implemented. In particular, the two construction packages of section 2 (Saigon River - Saigon Domaine Hotel) and section 4 (Saigon River - Ly Hoang Villa to La San Mai Thon Church) are behind schedule, so the investor plans to stop the contract and choose a new contractor to speed up the progress.
