Pipeline Renewal Insertion Method 'SDF Method'

Pipeline Renewal Insertion Method 'SDF Method'

Can be inserted without selecting the bending angle of existing pipes! Long pipes can be manufactured, reducing construction time!

The "SDF Method" is a new technique for renewing pipelines by inserting stainless steel flexible pipes into existing aged pipes of small to medium diameter, including those with bends, which cannot be constructed using conventional insertion methods. Since it can be inserted regardless of the bend angle of the existing pipe, fewer construction piles, such as vertical piles, are needed compared to other methods. Additionally, the ability to manufacture long pipes allows for reduced construction time, and both the starting and reaching piles can be made smaller than with other methods, resulting in less road surface restoration area, less construction-generated soil, and reduced generation of industrial waste. 【Features】 ■ Can be inserted regardless of the bend angle of the existing pipe ■ Shortened construction time due to the ability to manufacture long pipes ■ Reduction in road surface restoration area, construction-generated soil, and industrial waste ■ Excellent long-term corrosion resistance and durability ■ No occurrence of rust lumps or other issues due to corrosion, with no impact on water quality *For more details, please refer to the PDF materials or feel free to contact us.

Ground Replacement Method "Light Drain Columbus Method"

Ground Replacement Method "Light Drain Columbus Method"

To ensure that buildings continue to stand safely for a long time! Protecting buildings from the ground during frequent earthquakes.

The "Light Drain Columbus Method" uses EPS in a shape developed by our company, laid under the foundation and floor slab. By placing a thick layer of EPS (air layer) between the foundation concrete and the ground, it cuts off the edges and reduces vibrations (horizontal and vertical) from the ground. This prevents resonance in vibrating buildings and minimizes the energy of the vibrations. Additionally, during disasters or prolonged power outages without heating or cooling, it effectively utilizes natural energy, allowing for comfortable living without strain. 【Features】 ■ Utilizes natural energy ■ Enhances the durability of the foundation (floor slab) ■ Protects buildings from the ground during frequent earthquakes ■ Minimal temperature difference between the underfloor and indoor spaces ■ Allows for integrated use of underfloor and indoor spaces *For more details, please refer to the PDF materials or feel free to contact us.

HEP&JES method

Non-excavation underpass construction method using elements with JES joints.

The HEP&JES (High Speed Element Pull & Jointed Element Structure) construction method, developed in collaboration with JR East, is a rational construction technique for cross-sectional structures that combines the non-excavation HEP (High Speed Element Pull) method for pulling and laying elements with the JES (Jointed Element Structure) method, which uses steel elements as the main structural components. This method has been adopted in projects for grade separations under railways and highways, and as of May 2024, it has accumulated over 160 orders. We propose the HEP&JES method as a safe, short-term, and low-cost solution for eliminating level crossings and improving intersections aimed at urban regeneration. **Features** - Since the inserted elements are used directly as the main structural components, insertion work is completed in one go, minimizing the impact on tracks and road surfaces. - Various shapes of structures can be constructed without being limited by structural length. - The method allows for precise construction as elements are pulled from the target point on the arrival side. - Since the pulling reaction force is taken by the retaining wall on the arrival side, there is no need for reaction force equipment on the starting side. *For more details, please refer to the PDF materials or feel free to contact us.*

Eco Recharge® Method

Eco Recharge® Method

Enabling large-volume ascites with a small diameter!

The Eco Recharge® method (circular groundwater control method) is a technique aimed at lowering groundwater levels by pumping groundwater and injecting it back into the ground using the latest technology. By eliminating excess water, it significantly reduces construction costs. Groundwater pumped from deep wells and other pumping wells is first sent to a sand separator. Here, impurities such as sand contained in the groundwater are removed, and then it is sent to a receiving tank. By controlling the injection pump to maintain a constant water level in the receiving tank, groundwater is pumped into the ground from the injection well without excess or deficiency. 【Features】 ■ Economic efficiency ■ Environmental conservation ■ Safety *For more details, please refer to the PDF document or feel free to contact us.

Small-diameter pumping method

Small-diameter pumping method

Achieving small diameter and high lift drainage!

The small-diameter pumping method is a technique used to lower groundwater levels by pumping in areas with high groundwater levels. This method generates negative pressure by sending a jet fluid (water or air) to an ejector installed at the well's tip, allowing for groundwater extraction. Since there is no need for a submersible pump inside the well, the drilling diameter can be smaller and more economical compared to traditional deep well methods. Additionally, it can handle higher lift compared to well point methods. 【Features】 ■ Excellent applicability: It can pump groundwater at depths where well point methods are ineffective and in soils with lower permeability coefficients than those used in deep well methods. ■ Cost-effectiveness: By not installing a submersible pump inside the well, the drilling diameter can be reduced compared to deep well methods. ■ Usability: Since the equipment is located above ground, maintenance is easy. *For more details, please refer to the PDF materials or feel free to contact us.
