Soc Trang: Started exploiting sea sand mine to build highway

According to Vinaconex E&C Construction and Engineering Investment Joint Stock Company, the unit uses the mining method by running the suction nozzles of turtle ships along the sand surface on the seabed. This mining is spread out without creating deep holes, so it does not lead to erosion.

Sand mining vehicles are ready to go into action.

Director of My Thuan Project Management Board Tran Van Thi said that after July 1, the unit will transport to the construction site to pilot the expressway section passing through the provinces of Bac Lieu , Kien Giang and Ca Mau. From Km 81+000 to the end of the main route at Km 126+223 in Hong Dan district (Bac Lieu province); Vinh Thuan district (Kien Giang province); Thoi Binh district (Ca Mau province) and from Km 6+522 to Km 16+510 of the route connecting Ca Mau in the districts of Thoi Binh, Tran Van Thoi and Cai Nuoc (Ca Mau province).

Previously, the spokesman of the Ministry of Transport Uong Viet Dung sent a press release stating that currently, the Mekong Delta region is implementing the construction of expressway projects: Can Tho - Hau Giang , Hau Giang - Ca Mau component projects of the North - South Eastern Expressway Project phase 2021 - 2025, Chau Doc - Can Tho - Soc Trang Project and An Huu - Cao Lanh Project and a number of other key projects with a total demand for sand filling materials of about 50 million m3.

Although a special mechanism has been applied in the allocation of material mines, the Prime Minister and Deputy Prime Minister have regularly directed ministries, branches and localities with sand mines in the region to prioritize, allocate, increase capacity, and open new mines to serve the construction of projects. However, the source of river sand and the exploitation capacity have not yet met the demand and construction progress. In this situation, the Government and the Prime Minister have directed the Ministry of Transport to coordinate with relevant ministries and branches to study alternative material solutions, including studying the use of sea sand as roadbed material in suitable areas.

After implementing the pilot project on the DT.978 repaved section (in Bac Lieu province) of the Hau Giang - Bac Lieu expressway , the results showed that the physical and mechanical indicators met the standards for roadbed construction materials; the construction work of sea sand was carried out similarly to river sand, and so far there has been no sign of increased salinity in the surrounding environment. Currently, the Ministry of Transport has reported to the Prime Minister and notified localities of the results of the pilot use of sea sand; requesting localities to pilot the expansion of the use of sea sand as roadbed for projects with environmental conditions similar to the Pilot Project, considering applying standards on salinity tolerance of crops, agricultural land, and aquaculture water according to the guidance of the Ministry of Agriculture and Rural Development.

On that basis and based on relevant instructions, the Ministry of Transport continues to organize the pilot construction of expanding the exploitation of sea sand for roadbed to ensure the completion of the North-South Eastern Expressway phase 2021-2025, Can Tho - Ca Mau section by December 31, 2025.
