📋 Tender Overview
Continuing his mission to inspect and direct the work of responding to and overcoming the consequences of rain and floods in a number of central provinces, on the morning of October 31, Deputy Prime Minister Tran Hong Ha inspected the work of overcoming incidents and landslides on the La Son - Hoa Lien highway, the section passing through Da Nang city.

The La Son - Hoa Lien expressway is 66 km long, connecting Hue - Da Nang. Due to prolonged heavy rain, many locations on the route suffered landslides, soil and rocks filled the road surface, causing local blockages. Field reports showed that Km 8+100 had slope erosion, about 9,000 m3 of soil and rocks spilled onto the road surface, which has been cleared; Km 12+300 had about 1,500 m3 of landslides and has been treated. Due to prolonged heavy rain, many locations on the La Son - Hoa Lien highway were eroded and seriously damaged - Photo: VGP/Minh KhoiKm 14+00 and Km 16+600: Total about 8,000 m3, one lane has been opened, the rest is being completed. Km 41+450 to Km 42+800: The volume of landslides increased sharply, estimated total from 35,000 - 42,000 m3, cleanup is underway, expected to take many days to complete. Notably, intersection N1 (Khe Tre) - the connection point between La Son - Hoa Lien Expressway and National Highway 14B - is one of the most seriously eroded areas.

The estimated landslide volume was about 5,000 m3, high slopes, sloping terrain, weak soil, and prolonged rain caused the roadbed and drainage ditch structures to be broken, and there is a risk of further landslides when there is additional rain. Currently, the construction units are maintaining the force, excavators and dump trucks 24/7, focusing on clearing landslides, at the same time drilling anchors and spraying temporary concrete to reinforce the roof, expected to complete step 1 before November 2. At Km50 + 700 - Km50 + 800, the section through the sloping terrain area, the slope is high, there is a crack in the road surface about 80 m long, 5-10 cm wide, the cross-section shows signs of roadbed movement and subsidence. locally. Units have erected warning barriers, waterproof covers, limited traffic loads, and arranged technical teams to monitor deformation hourly. At the point of slope failure and road surface cracks at Km 50+700 - Km 50+800, the Deputy Prime Minister requested a reassessment of all geological factors in the area, including inviting an independent professional agency to participate to determine the level of water saturation, deep and stable sliding status. determination of roadbed and slope. The Deputy Prime Minister emphasized that each landslide must have its specific cause assessed, and appropriate technical solutions selected to ensure the long-term sustainability of the expressway - Photo: VGP/Minh Khoi The geology must be fully re-evaluated, with an independent agency participating. The landslides have clear causes. If the design has not taken into account, it must be recalculated, the Deputy Prime Minister emphasized. The design consulting unit must carefully study and propose plans. fix the basics, ensure safety, do not do temporary work, do it once and for all, do not let it recur when there is heavy rain. The Deputy Prime Minister emphasized that each landslide must have its specific cause assessed, appropriate technical solutions will be selected, ensuring the long-term sustainability of the expressway. It must be overcome scientifically and thoroughly. Do it once, so that it does not happen a second time, the Deputy Prime Minister said. The Deputy Prime Minister requested the Ministry of Construction to set up a professional council and Send a working team directly to the site to evaluate the plan and appraise it before implementation. Representatives of the Ministry of Construction were assigned to immediately coordinate with the Government Office to organize a working group as soon as possible. The Deputy Prime Minister directed to continue banning all vehicles from traveling through potentially unsafe roads, to prevent people from mistakenly entering dangerous areas - Photo: VGP/Minh Khoi. The Deputy Prime Minister noted the risk of continued landslides due to saturated geology and loss of slope footing, requesting consultants and relevant units to calculate an overall solution to stabilize slopes, including: Adding drainage ditches; anchor drilling, reinforcement, spraying to protect slopes; or build a retaining wall, depending on the technical assessment of each location. Regarding the work of ensuring traffic safety, the Deputy Prime Minister directed to continue banning all vehicles from traveling through the road section at risk of unsafety, assigning traffic police and local police forces to organize remote traffic diversion and early notification so that people and vehicles can proactively change directions. The fix will not be completed quickly. Therefore, we must block both ends, clearly divide the channel, and not let people mistakenly enter dangerous areas, said Deputy Prime Minister.Minh KhoiSee moreSee moreSee moreSee moreSee moreSee moreSee more
