Upgrading ĐH.14 Road: NH38 Bypass – Đầm Đọ (Duy Tiên, Hà Nam)
The Project for Rehabilitation and Upgrading of Road ĐH.14, with a Total Investment of VND 136.834 Billion, Promoting Infrastructure and Industrial Development in Chau Giang Ward, Duy Tien, Ha Nam.
The ĐH.14 road section from the National Highway 38 bypass to Dam Do residential area, Chau Giang Ward, Duy Tien Town, Ha Nam Province, is one of the key infrastructure projects serving regional traffic and providing direct connectivity to the Chau Giang industrial cluster. With a total investment of up to VND 136.834 billion, the project is expected to create a strong impetus for socio-economic development, while upgrading traffic conditions and reducing vehicle congestion through residential areas.
In this article, Hanoi Vietnam provides an in-depth analysis of the technical aspects, practical performance, construction costs, and comparisons with similar road rehabilitation projects, thereby supporting engineers and investors in making well-informed decisions.
Geological Characteristics of the Bridge over Moc Nam Canal
The geological conditions at the bridge construction site over Moc Nam Canal are assessed as relatively complex, with interbedded layers of soil, clay, and sand. These conditions directly affect the selection of construction equipment as well as foundation reinforcement solutions.
Specifically, the ground consists of existing fill layers, interspersed with gray-brown, yellow-gray, and blue-gray clay in conditions ranging from soft plastic to stiff plastic. In particular, some clay layers mixed with organic remnants in a very soft to flowing state pose potential risks of settlement if not properly treated. Alternating with these are layers of silty sand, fine sand, and gravel, many of which reach medium-dense to very dense states, providing favorable conditions for bored pile toe placement once the required depth is achieved.
A thorough understanding of the geological conditions enables the contractor to proactively select appropriate drilling rigs, drilling tools, borehole stabilization methods, and to plan solutions for drilling slurry treatment. This is a key factor in ensuring the durability and stability of bored piles for the bridge foundation.
Bored Pile Construction Method Implemented by Hanoi Vietnam
As the direct contractor responsible for the bored pile works of the bridge, Hanoi Vietnam Co., Ltd. selected the construction method using the HITACHI KH180-3 drilling rig equipped with an R10 drilling bucket. This high-capacity rig offers deep drilling capability, excellent stability, and is well-suited to the complex geological conditions of the area.
According to the design, the drilling bucket is lowered from the natural ground level to the pile toe elevation, with an average depth of 45 meters. During drilling, bentonite slurry is used to stabilize the borehole, while settlement and drilling slurry quality are strictly monitored to prevent borehole collapse.
The selection of the R10 drilling bucket provides outstanding advantages in terms of penetration speed through hard soil layers and dense sand–gravel strata, ensuring construction progress while maintaining precise pile diameter control. This is a crucial preparation step to ensure that the bridge foundation can achieve high load-bearing capacity and long-term durability.
Socio-Economic Benefits of the ĐH.14 Road Rehabilitation and Upgrade Project
Beyond its technical and infrastructure value, the project carries significant importance for local development. Once rehabilitated and expanded, the road will:
- Enhance traffic connectivity between the National Highway 38 bypass and the urban area of Duy Tien as well as the Chau Giang industrial clusters.
- Reduce traffic congestion, especially during peak hours when vehicles from industrial zones pass through residential areas.
- Promote local economic development, creating favorable conditions for investment attraction and industrial expansion.
- Improve residents’ quality of life by upgrading transport infrastructure, shortening travel times, and increasing road safety.
This represents the project’s dual objectives: addressing immediate infrastructure needs while opening long-term opportunities for sustainable development in Duy Tien Town in particular and Ha Nam Province as a whole.
Conclusion
The rehabilitation and upgrading project of Road ĐH.14, from the National Highway 38 bypass to Dam Do residential area in Chau Giang Ward, Duy Tien Town, is a major infrastructure project with a total investment exceeding VND 136 billion. The geological conditions at the bridge over Moc Nam Canal are relatively complex, requiring precise selection of bored pile construction methods.
With extensive experience and modern equipment such as the HITACHI KH180-3 drilling rig, Hanoi Vietnam Co., Ltd. is confident in ensuring construction quality, schedule compliance, and safety for the project. This project marks an important step forward in infrastructure, industrial, and community development in the Chau Giang – Duy Tien – Ha Nam area.
