The "Vacuum Consolidation Drain Method" is a technique that uses drains equipped with airtight caps and drainage hoses to achieve consolidation improvement through negative pressure. By utilizing the upper clay layer as a negative pressure sealing layer, it allows for consolidation improvement without the need for a sealing sheet on the ground surface, which was essential in conventional vacuum consolidation methods. Since it can be transported and installed with the airtight cap and drainage hose attached, on-site work can be simplified, and it can be efficiently installed using standard drain construction equipment. Because a sealing sheet is not required, it can also be applied to ground improvement below the water surface, which was difficult with conventional methods. 【Features】 - Does not cause shear failure - No need for fill materials or sand mats - Can be used in conjunction with loaded fill - An environmentally friendly method that does not use chemical solidifying agents like cement - NETIS registered (No.HK-060002-V) For more details, please contact us or download the catalog.
