The "T・PJOINT" is a connection plate and joint method that consists of end parts, side plates, reinforcement bands, connection plates, and connection bolts, and is a non-welded joint. The connection plate has a concave shape that fits with the protrusions of the end plate, and by attaching the connection bolts to the screw holes of the side plates, the concave and convex parts are engaged, transmitting the stress acting on the joint through this engagement. Additionally, the connection bolts serve to prevent the connection plate from detaching when tensile forces act on the joint. 【Features】 ■ Has performance equivalent to welded joints ■ Less affected by weather conditions (wind, rain, temperature, etc.), allowing for stable construction ■ Can be safely constructed even in areas where open flames are prohibited ■ Shorter construction time compared to welded joints ■ The connection plate is divided into three parts for weight reduction, making it easy to handle *For more details, please refer to the PDF materials or feel free to contact us.

The "MY Best Construction Method" is a technique that integrates straight piles with the ground to develop bearing capacity. Since the piles are installed while compacting the soil against the hole walls, the amount of residual soil generated is significantly less compared to conventional pre-boring methods. Additionally, the frictional force from the compacted ground around the piles and the solid anchoring section allows for the assurance of a very large bearing capacity. [Features] - Integrates straight piles with the ground to develop bearing capacity - Generates significantly less residual soil compared to conventional pre-boring methods - Ensures a very large bearing capacity *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The "G-Lock Method" involves straight drilling, making the excavation process simple and improving construction efficiency through a pre-boring expansion grouting method. Since the tip of the pile's grouting section is inserted 5D (D: pile diameter) into the supporting layer (N value of 30 or more), the pile's bearing capacity coefficient α=348 is significantly high, ensuring reliable bearing capacity. By using an excavation mixing device, the injection fluid is mixed with the ground, allowing for a reduction in the amount of excavated residual soil. 【Features】 ■ Improved construction efficiency ■ Straight drilling ■ Reliable high bearing capacity ■ Enhanced construction quality and easier construction management ■ Reduction of excavated soil volume *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction Method

The "pairing joint" is a non-welded joint pile that can be used with all prefabricated piles. It allows for stable construction unaffected by weather conditions such as rain, wind, snow, and low temperatures. Its resistance to bending, shear, and tension is equivalent to that of welded joints. Additionally, since welding is not required, it can be used in sites where flammable gases are likely to be generated or in chemical plants handling combustible materials. 【Features】 ■ Easy construction management, leading to shortened construction periods ■ Unaffected by weather conditions ■ Usable in fire-restricted sites ■ Stable quality due to factory production ■ Joint strength is equivalent to that of welded joints *For more details, please refer to the PDF document or feel free to contact us.

The "T・P JOINT (Triple Plate Joint)" is a non-welded joint that is less affected by weather conditions (such as wind, rain, and temperature) and allows for stable construction. The tightening of the connection bolts is done using a torque wrench, requiring no special tools or skilled workers, making construction management easy. Additionally, the protrusion of the connection plate from the pile body is small, which minimizes the impact on the frictional force around the pile surface. 【Features】 ■ Equivalent performance to welded joints ■ Less affected by weather conditions, allowing for stable construction ■ Safe construction even in areas where open flames are prohibited ■ Shorter construction time compared to welded joints ■ Easy to handle *For more details, please refer to the PDF materials or feel free to contact us.

The "High Bearing Capacity Pile Method (H・B・M)" enables the reduction of pile diameter and the number of piles used through high bearing capacity pile design, achieving a shortened construction period for foundation work and a reduction in excavated soil. By adopting HB piles with enlarged diameters, it obtains the specified values of the astonishingly high bearing capacity coefficients α, β, and γ (as per the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1113). To match the large ground bearing capacity, ultra-high-strength concrete piles with a strength of over 105 N/mm² have been developed, and a group of manufacturing factories affiliated with the association provides high-quality products. 【Features】 ■ Ensures ultimate α, β, and γ values ■ Constructs environmentally friendly foundations ■ High-quality construction covering all of Japan ■ Concrete pile materials entering a new era ■ 8 types of selection variations *For more details, please refer to the PDF materials or feel free to contact us.

• Special Construction Method

The "Hyper-Straight Method" is a pre-boring expansion solidification method where the ground is first excavated using an auger, followed by the injection of solidification liquid and pile surrounding fixation liquid, allowing the pile to be inserted into the designated support layer by self-sinking or rotation to a depth of 1D or more. Using a drilling and mixing device composed of an auger head, screw, mixing rod, and connecting rod, the construction is carried out through a sequence of steps from excavation to the injection of solidification liquid, repeated solidification of the solidified section, injection of pile surrounding fixation liquid, repeated fixation of the surrounding section, and installation of the pile. Additionally, by introducing a construction management system that supports high precision and efficiency, real-time management of the solidification bulb section and support layer is conducted to ensure quality. 【Features】 ■ Pile tip bearing capacity coefficient α=363 ■ Simple construction ■ Use of standard precast concrete piles ■ High bearing capacity at low cost ■ Construction management *For more details, please refer to the PDF document or feel free to contact us.

• Special Construction Method

The "STJ Method" is a construction technique that involves high-pressure injection of cement milk from an STJ bit to create an enlarged bulb, integrating it with the ground to develop bearing capacity. By switching the auger's rotation to a low speed and jetting cement milk from two high-pressure injection nozzles while pulling it up at a constant speed, it is possible to reliably construct an enlarged bulb. Compared to the pre-boring method, it is a low-discharge method, and the discharged soil is natural soil, contributing to a circular economy. 【Features】 ■ Low noise and low vibration method ■ Reliable construction of enlarged bulbs ■ High bearing capacity ■ Rapid construction ■ Low construction costs *For more details, please refer to the PDF materials or feel free to contact us.

The "Kemun Method/ST Kemun Method" is a pre-boring expansion grouting method that adapts to various ground conditions and ensures reliable anchoring to the bearing layer. The "Kemun Method" allows for construction using small-diameter to large-diameter piles, and by injecting pile fixing fluid along the entire circumference of the pile, friction can be expected. The "ST Kemun Method" can address horizontal forces by combining PHC piles of types B and C, PRC piles, SC piles, etc., with the upper piles. 【Features of the Kemun Method】 ■ Low vibration and low noise construction ■ Reliable anchoring of piles to the bearing layer ■ Construction possible from small-diameter to large-diameter piles ■ Adaptable to various ground conditions ■ Extremely low soil displacement compared to conventional cement milk methods *For more details, please refer to the PDF document or feel free to contact us.
