Hyundai Engineering and LH Sign Win-Win Agreement for Heater Pile Construction New Technology

[Asia Economy Reporter Yuri Kim] Hyundai Engineering and Korea Land & Housing Corporation (LH) announced on the 17th that they have signed a win-win agreement to promote the development and expanded application of new construction technology (Heater Pile).

The signing ceremony held at the LH headquarters in Jinju, Gyeongnam was attended by Hwang Heon-gyu, Vice President and Head of Hyundai Engineering's Architecture Business Division, Kwon Hyuk-rye, Head of LH's Public Housing Division, and officials from Sampyo P&C and BTENC.

The main contents of the win-win agreement signed that day include ▲ technology exchange related to new technology ▲ promotion of technology improvement and additional research projects related to new technology.

The technology designated as Construction New Technology No. 891 by the Ministry of Land, Infrastructure and Transport in August, titled "High-temperature curing method of cement slurry using water-heated heater in the hollow part of piles for early confirmation of bearing capacity of driven piles," is a cement slurry high-temperature curing technology for driven piles jointly developed by Hyundai Engineering, LH, Sampyo P&C, and BTENC.

Piles are structural elements used in construction to safely support structures such as high-rise buildings, bridges, and foundations on soft ground. The typical method of installing driven piles involves drilling holes into the ground, inserting precast piles, and filling the gap between the pile and the ground with cement slurry.

To apply driven piles on-site, a bearing capacity confirmation test must be conducted after curing the cement slurry. The curing process usually takes about seven days to secure the bearing capacity. The newly developed technology, Heater Pile, fills the hollow part of the pile with water and heats it with a water-heated heater to rapidly cure the cement slurry around the pile. Applying this technology can reduce the curing period of the cement slurry from more than seven days to within one day.

Because the cement slurry can be cured in a short period, the bearing capacity of the pile can be confirmed without waiting time for the testing equipment. From a design perspective, this technology allows for increasing the design load or reducing the pile length compared to the same design load, enabling construction efficiency and cost savings through optimal design.

Hyundai Engineering, together with Sampyo P&C and BTENC, jointly developed and registered related patents in 2015 and has continuously applied this technology on its sites to secure cost reduction and construction quality stability. LH supported the development of this new technology by providing research on site applicability and technical support.

A Hyundai Engineering official said, "With the signing of this win-win agreement, the utilization of new technology will be promoted, and technology exchange and sharing of construction experience among the companies will be further expanded."
