Project Description

Project: High-rise residential area combined with trade and service. Located at 765 Hong Bang, Ward 6, District 6, Ho Chi Minh City.

Construction unit: Mekong Investment Construction Co., Ltd

Supervision Consultant: Bach Khoa City Science and Technology Joint Stock Company. Ho Chi Minh City

Las 92 Joint Stock Company is the testing unit to verify the quality of the works, performing the test items such as: Determination of the verticality of the borehole wall (KODEN TEST), ultrasonic testing for the homogeneity of concrete. bored piles, drill to check the thickness of the pile tip for the project.

Experimental work KODEN TEST


Every execution pile is supervised by stakeholders


In the previous article, we introduced customers to better understand the pile ultrasonic testing method as well as the PDA method.

Next, we will introduce the KODEN bored pile test method and the standards applied to the process of implementing this method.

Did you know about the purpose of KODEN experiment in the construction of bored piles?

Piles are widely used in foundation construction. When drilling it is very important to check the verticality and bore size.

Therefore, checking the verticality to determine the distance and obliqueness of the borehole is very necessary and important in the evaluation of construction quality.



The test work to determine the verticality of the borehole wall is carried out based on the applicable standard: TCVN 9395:2012. Construction and acceptance of bored piles

The system of equipment used for testing is the DM-604 or DM-604R machine of KODEN, manufactured in Japan.

During the testing process of KODEN pile/diaphragm wall of Las 92, there is always the full supervision and witness of relevant parties such as Supervision Consultant, Construction and site technicians to ensure the results are in the most accurate and authentic way.
