On the morning of April 21, Lieutenant Colonel Tran Quang Hoat, Deputy Director of Truong Son 10 Management Board, Truong Son Construction Corporation, said that the unit has started exploiting sand mines on Hau River, the section belonging to Binh Thuy Commune, Chau Phu District and Binh Thanh Dong Commune, Tan Hoa Commune, Phu Tan District assigned by the People's Committee of An Giang Province, serving the construction of Chau Doc - Can Tho - Soc Trang Expressway Phase 1, the section passing through Hau Giang Province.
The sound of machines on the construction site
Lieutenant Colonel Hoat informed that in order to exploit this sand mine, Truong Son Construction Corporation has arranged three scrapers, with a bucket capacity of 3.5m3, and enough workers to serve the sand mining work according to regulations.
"This is the second sand mine assigned by the An Giang Provincial People's Committee to Truong Son Construction Corporation for direct exploitation to serve the construction of the Chau Doc - Can Tho - Soc Trang expressway.
Previously, Truong Son Construction Corporation also started exploiting the first sand mine to serve the cross-axis highway in the West, the section passing through An Giang province," Lieutenant Colonel Hoat shared.
The third sand mine serving the construction of the Chau Doc - Can Tho - Soc Trang expressway has begun exploitation.
Mr. Truong Thanh An (41 years old), a sand mining worker at Truong Son Construction Corporation, said that he has nearly 20 years of experience mining sand for construction projects.
"We will uphold our spirit and responsibility to bring sand to the construction site soon," Mr. An added.
With 25 years of experience in sand mining for the construction of many important projects, Mr. Do Van Da (47 years old), a sand mining worker at Truong Son Construction Corporation, shared: "The first thing we workers need to do is to mine according to regulations on depth and permitted reserves."
Still need new sand mines
Also according to Lieutenant Colonel Hoat, the sand mine on Hau River, in Binh Thuy Commune, Chau Phu District and Binh Thanh Dong Commune, Tan Hoa Commune, Phu Tan District (An Giang) has an area of 61.47 hectares. The permitted volume of exploitation is 2,625,631 m3.
This sand mine has a permitted exploitation capacity of 1,312,816m3/year. In the first year, the capacity is 1,312,816m3/year and in the second year, the capacity is 1,312,815m3/year.
Mining depth is minus 16m. Mining method is open-pit. Project implementation time is 2 years and 6 months, of which mining time is 2 years and environmental improvement and restoration time is 6 months.
"Every day, workers start working from 7am to 5pm, no mining at night with the daily allowed mining quantity being 3,700m3 of sand/day," said Lieutenant Colonel Hoat.
More sand is needed to ensure the progress of the construction of the cross-axis highway in the West.
And Lieutenant Colonel Hoat added that the Chau Doc - Can Tho - Soc Trang expressway package, the section through Hau Giang province, is being constructed by Truong Son Construction Corporation with a total length of 18.8km, with the amount of sand needed to fill the foundation being 2.1 million m3.
With the sand mine granted by the An Giang Provincial People's Committee under a special mechanism, the total amount of sand is enough for construction. However, the permitted daily exploitation reserves do not meet the current actual demand at the construction site, because depending on the stage - sometimes a lot is needed, sometimes a little.
Currently, the construction site needs about 8,000m3 of sand/day to fill the foundation to ensure construction progress. However, the amount allowed to be brought to the construction site each day is 3,700m3 of sand/day, which is still not enough.
According to calculations by professional agencies, to ensure technical factors, the package implemented by Truong Son Construction Corporation, depending on the section, requires a loading time of 10-12 months.
Meanwhile, with the amount of sand allowed to be exploited daily, it would take up to two years for this sand mine to fully exploit the permitted reserves.
At the same time, increasing daily mining capacity is also facing difficulties due to many factors related to environmental impact.
"The contractor wants to add another sand mine. And this additional sand mine can be exploited in June or July so that the construction can be guaranteed to meet the planned progress," informed Lieutenant Colonel Hoat.
Previously, to provide sand for the construction of the longitudinal and transverse expressways in the West, An Giang province granted contractors to directly exploit 10 sand mines with a total reserve of 15.2 million m3.
Up to now, there are 4 sand mines supplying Can Tho - Ca Mau expressway being exploited, with total reserves of about 4.7 million m3.
Meanwhile, three sand mines supplying the Chau Doc - Can Tho - Soc Trang expressway have also begun exploitation with a total reserve of more than four million m3.
The Chau Doc - Can Tho - Soc Trang Expressway Project Phase 1 has a total length of 188.2km, passing through four provinces and cities: An Giang, Can Tho, Hau Giang and Soc Trang. The starting point connects to National Highway 91 in Chau Doc city (An Giang) and the end point intersects with Nam Song Hau National Highway, connecting to Tran De port access road (Soc Trang), with a total investment of 44,691 billion VND. The entire route is expected to be completed and put into use in 2027.
Of which, component project 1 in An Giang province is 57.2km long, component project 2 in Can Tho city is 37.2km long, component project 3 in Hau Giang province is nearly 37km long and component project 4 in Soc Trang province is 56.9km long.
In phase 1, the project will be invested in a 4-lane scale, with a design speed of 100km/h. In the final phase, the project will be invested in a 6-lane scale.
