The NAKS method is classified as an embedded pile method using precast concrete piles and is a middle excavation enlarged root solidification method. This method involves excavating the ground at the pile tip using a spiral auger inserted into the hollow part of the pile and a specially designed mechanical or hydraulic enlarged bit, allowing the pile to be installed by its own weight or forced pressure input. The enlarged bit excavates below the outer diameter of the pile until it reaches the supporting layer, at which point the enlarged wings open wider than the outer diameter of the pile, creating an enlarged bulb at the pile tip through the mixture of solidification fluid and sand/gravel from the supporting layer. 【Features】 ○ Reliable track record ○ High bearing capacity with a safe and secure method ○ Minimal amount of excavated soil ○ Improved construction accuracy ○ Low noise and vibration with no secondary pollution For more details, please contact us or download the catalog.

■Generator processing airflow Q=23,760m3/ x 7 units ■Noise level per generator 78dB(A), 86dB(A) for 7 units ■Permissible noise level at the property boundary 60dB(A) <Summary of Measures> 1. Exhaust noise countermeasures for the generator → Weather-resistant GW silencer 2. Body noise countermeasures for the generator → Porous sound-absorbing composite panels 3. Intake noise countermeasures for the generator → Weather-resistant GW silencer The key point of the measures is to allow the generator to breathe without putting a burden on it while satisfying the target permissible noise level. Therefore, instead of surrounding the entire generator with soundproof walls, we considered the minimum necessary range for soundproofing and decided to install intake silencers at the bottom of the soundproofing and exhaust silencers at the top of the exhaust. By implementing these measures, intake occurs from the bottom and exhaust from the top, which also contributes to shortcut measures, resulting in good operation of the generator and satisfaction of the permissible noise level.
