D-TEC PILE Method (Rotary Driven Steel Pipe Pile Method)

D-TEC PILE Method (Rotary Driven Steel Pipe Pile Method)

A steel pipe pile method that achieves stable quality by integrally forming the tip components with cast steel!

The "D-TEC PILE Method (Rotary Driven Steel Pipe Pile Method)" is a construction method that allows for the management of reaching the bearing layer for all piles by measuring the rotational torque. Steel pipe piles are used to penetrate the ground and prevent differential settlement of buildings on soft ground. By attaching circular wings to the tip of the steel pipe piles and giving them a spiral shape, construction time can be shortened, and the bearing capacity can be increased, thereby reducing the number of piles required. Additionally, for the joints, a plug-type joint that does not require on-site welding has been adopted, achieving improvements in quality and operability. 【Features】 - Low noise and low vibration among foundation reinforcement methods - No residual soil generated - Management of reaching the bearing layer for all piles is possible by measuring the rotational torque - Stable quality is achieved by integrally molding the tip components in cast steel *For more details, please refer to the catalog or feel free to contact us.

Sewer Composite Manhole Rehabilitation Method "Eba Sheet Method"

Sewer Composite Manhole Rehabilitation Method "Eba Sheet Method"

Long-lasting corrosion-resistant manholes! A sewer composite manhole rehabilitation method that achieves material savings.

The "Evashito Method" is a composite manhole rehabilitation technique that involves installing an "FRP sheet" on the corroded inner wall of an existing manhole using an expansion frame, and filling the gap between the sheet and the existing manhole with mortar. The backside treatment of the FRP sheet creates a rough surface with the adhered silica sand, enhancing the adhesion strength with the filling material and achieving a complete integration with the existing manhole, resulting in strong durability. No heavy machinery is required, and no special skills are needed, allowing for construction in a small road occupancy area. By utilizing the existing manhole, material savings are achieved, along with a reduction in construction time, making it highly economical. 【Features】 ■ High quality ■ High speed ■ Low cost ■ Can be constructed in a small road occupancy area ■ Achieves material savings by utilizing existing manholes *For more details, please refer to the PDF document or feel free to contact us.

Super Spiral Bolt SP24

Super Spiral Bolt SP24

The head protection materials (cap/mat) for waterproof sheet installation are no longer necessary.

The "Super Spiral Bolt SP24" is a high-strength locking bolt that inherits the excellent features of the "SN Twist Bolt." It features a newly designed special rib and screw section that are simultaneously formed during the round steel rolling process, resulting in no cross-sectional defects in the screw section and consistent strength throughout its length. 【Excellent Characteristics】 - It uses high-strength material SD685, achieving a high yield load of over 297 kN while being even lighter (3.4 kg/m) than the SN Twist Bolt. - By maintaining the same material diameter and reproducing the surface shape of the SN Twist Bolt, the insertion resistance is equivalent to that of the SN Twist Bolt. - It inherits the excellent anchoring characteristics of the SN Twist Bolt, with high adhesion toughness against ground deformation during the early age of the anchoring material, making it less prone to adhesion failure. - The adoption of the special-shaped nut "S Nut" reduces the protrusion of the nut and bolt, eliminating the need for protective materials (caps/mats) during waterproof sheet installation. *For more details, please refer to the PDF document or feel free to contact us.*

Construction method "Hybrid Fore-Piling"

Construction method "Hybrid Fore-Piling"

Enhance blade stability with a combined pattern of "long-length fore piling" and "long-length mirror reinforcement work."

"Hybrid Fore-Piling" is a construction method that is expected to have a higher effect in suppressing the plasticization of surrounding ground. By placing small-diameter steel pipes from the upper part of the mirror section towards the top, it is possible to reinforce not only the "top section" that is reinforced by conventional fore-piling but also the "upper ground of the mirror surface," which has a high risk of collapse. [Features] - By increasing the overlap section, it can reinforce the surrounding ground over a wide area, including the mirror section. - Compared to conventional fore-piling, it has a higher effect in suppressing the plasticization of the ground. - By using small-diameter steel pipes (φ76.3), it is more economical than before. *For more details, please refer to the PDF materials or feel free to contact us.

The "GPR method" is a groundbreaking repair technique that applies the technology of steel pipe expansion-type lock bolts to repair corroded parts of guardrail posts. It features simple work that does not require exploratory drilling and does not need special construction techniques. Additionally, the construction equipment is compact, and the work time per location is extremely high at just 10 to 20 minutes. [Features] ■ Adoption of highly corrosion-resistant plated materials ■ Simple construction that does not require special construction techniques ■ Instant repair from the inside of the post using expansion steel pipes ■ Speedy construction ■ No exploratory drilling required *For more details, please refer to the PDF materials or feel free to contact us.

Shear Reinforcement Method "RMA Method"

Shear Reinforcement Method "RMA Method"

Construction technology certification acquisition method! No need for mortar mixing or installation of injection holes on site!

The "RMA method" is a shear reinforcement method that allows for reinforcement without encroaching on the inner cross-section of continuous walls. It employs capsules containing premixed mortar as a bonding agent. This method enables construction using impact techniques for long or thick reinforcing bars, making it a post-installed method. Since there is no need for mortar mixing or the installation of injection holes on-site, special management is unnecessary. Reinforcement is carried out only for the insufficient shear capacity, allowing for a transition from shear failure-dominant to bending failure-dominant. 【Features】 ■ Drilling can be done with a small diameter and only once ■ No mixing on-site, maintaining consistent quality ■ Simple product composition and construction method, reducing construction time ■ Minimal interference with existing structural rebar, allowing for reduced re-drilling due to high stopping capability ■ A method that does not use large or special machinery, saving space *For more details, please refer to the PDF document or feel free to contact us.

Gainamesh method [fall prevention measures]

Gainamesh method [fall prevention measures]

It has excellent durability, conforms to the curved surfaces of tunnels, and prevents the spalling of concrete fragments.

■NETIS Registered, Registration Number: KK-240048 ■High-strength aramid fibers reliably prevent the spalling of concrete pieces. This construction method aims to prevent the spalling of concrete pieces in concrete structures using GFRP shape retainers and high-strength aramid fiber mesh, ensuring the safety of users of the structures. *This meets the quality standards specified in the NEXCO Tunnel Construction Management Guidelines. 【Features】 The mesh part allows for visual inspection after construction. By using high-strength aramid, there is less alkali deterioration due to groundwater, and since it does not conduct electricity, it can also be applied in railway-related tunnels. Installation is quick and easy, as it only requires driving in strike anchors. Additionally, if any deformation is observed after construction, maintenance such as removing and reattaching the fixing screws can be easily performed. By using a locking K-nut with a friction ring (leaf spring), it provides a function to prevent detachment, enhancing safety. This locking K-nut meets NAS standards, which are specified as verification items during material approval by NEXCO.
