On July 28, the Traffic Project Management Board of Lam Dong province said it was coordinating with Deo Ca Construction Joint Stock Company - the construction unit of the project to upgrade and expand Prenn Pass to overcome the problem of subsidence and cracking. Road surface at Km228+506-Km228+530.
Accordingly, after examining the actual scene at Prenn Pass, it has been shown that in recent times the area has been raining continuously with heavy rainfall. So at a local location, water has penetrated deep into the ground under the roadbed, possibly causing water saturation.
At the same time, the soil under the roadbed has a high clay content, leading to reduced binding and bearing capacity, causing local damage (cracking of the upper road surface).
The construction contractor proactively reported to the Traffic Project Management Board of Lam Dong province and the Design Consultant, and at the same time handled the solution by using plastic putty to fill the cracks to prevent water from penetrating the foundation. road, organize monitoring of crack developments.
The parties continue to monitor possible changes on the Prenn pass . In the near future, solutions will be proposed to deal with the problem immediately after the end of the rainy season.
Mr. Pham Van Hung - General Director of Deo Ca Construction Joint Stock Company said that during project implementation, the contractor always complied with the design documents. The instructions, technical standards, and construction methods have been closely inspected and accepted by the investor and the supervision consultant.
