The "Hayak Pressure-In Caisson Method" is a construction technique that utilizes anchors driven into the ground to take reaction forces, which are transmitted to a pressure jack via a gripper rod. This method allows for the controlled tilting of the structure while ensuring that the structure is securely sunk into the ground. The total load capacity of multiple hydraulic jacks installed on the top surface of the caisson ranges from several hundred tons to several thousand tons. By operating these jacks alternately or simultaneously, posture control is achieved, enabling highly accurate sinking. In recent years, advancements in excavation patterns and jack control technology have allowed this method to meet the demands of the times, resulting in a wide range of applications. 【Features】 ■ Enables highly accurate sinking ■ Improved control technology ■ Utilizes relatively simple equipment and has a long history ■ Suitable for challenging construction: in narrow spaces or areas with overhead restrictions *For more details, please download the PDF or feel free to contact us.

• Ground foundation construction method

We would like to introduce our "Bridge Foundation Construction" utilizing the "Hayak Pressure Insertion Caisson Method" that we are implementing. This method can be executed on construction sites that require land for structures, excavation machinery, and soil disposal equipment. It is a construction method that matches the narrow construction conditions in urban areas. 【Features】 ■ Capable of creating highly reliable foundations for bridge foundations such as roads and railways ■ Compact construction that can accommodate narrow construction yards *For more details, please download the PDF or feel free to contact us.

• Ground foundation construction method

We would like to introduce our "Underground Pump Room and Underground Storage Pond Construction" utilizing the "Hayak Pressure Insertion Caisson Method." In conventional methods, issues with water leakage in structures arise due to depth and soil conditions. Given the high reliability of the caisson method for constructing permanent structures above ground, the adoption of the pressure insertion caisson method is increasing. 【Features】 <Underground Pump Room and Underground Storage Pond Construction> ■ Capable of constructing deep and large-diameter shafts ■ Most of the work can be done from above ground, which is advantageous in terms of safety and cost *For more details, please download the PDF or feel free to contact us.

• Renovation and repair methods

We would like to introduce the "shaft construction for shield and thrust" utilizing our "Hayak Pressure-in Caisson Method." Shield construction planned in urban civil engineering often requires deep excavation to avoid existing underground structures such as subways and water pipelines. As a result, the adoption of the pressure-in caisson method is increasing, considering the impact on the surrounding area and safety. [Features] <Shaft Construction> ■ Capable of constructing deep and large-diameter shafts ■ Most of the work can be done from the ground, which is advantageous in terms of safety and cost *For more details, please download the PDF or feel free to contact us.

• Renovation and repair methods

We would like to introduce our "Low Space Construction" utilizing the "Hayak Pressure-In Caisson Method" that we employ. This method enables low space construction, such as under elevated structures, by appropriately planning the construction base surface and the height of the construction lot. *For more details, please download the PDF or feel free to contact us.
