Construction Method: Circle Cutter Method

Construction Method: Circle Cutter Method

It is a construction method that allows for low noise, vibration-free, and space-saving rapid installation in the replacement of manhole frames and covers.

This is a construction method ideal for replacing iron covers, characterized by speed, recyclability, and low cost. The weight of the cutter machine is 20 kg, and since it is dry, the asphalt dust generated after pavement cutting is collected and recycled using a dust collector. By using jigs for corner covers, the pavement cutting results in no leftover cuts, with the corners enclosed by arcs. Additionally, recycled materials such as steel slag are used, allowing for traffic release at each location with cold rapid-hardening pavement materials.

Cutting soil reinforcement method "Green Panel (FRP pressure plate method)"

Cutting soil reinforcement method "Green Panel (FRP pressure plate method)"

Easy to install and significantly shortens construction time! This method is also suitable for reverse installation.

This construction method involves fixing FRP lattice-shaped green panels as slope protection materials with reinforcement at the top, utilizing the tensile strength of the reinforcement to prevent slope collapse. By spraying materials such as soil onto this part, full greening, which was difficult with conventional slope protection methods, becomes possible. 【Features】 ■ NETIS Registration No. CG-010007-V ■ Lightweight at 16.8 kg due to being made of FRP ■ Easy to install ■ Significantly reduces construction time ■ High opening ratio due to lattice shape, enabling full greening *For more details, please refer to the PDF materials or feel free to contact us.

Construction Method: Multi-Mall Method

Construction Method: Multi-Mall Method

The multi-mole method is a mechanized technique for horizontal thrusting and vertical excavation work during the installation of sewer connection pipes and public manholes.

During the installation of sewer connection pipes and public manholes, it is necessary to dig horizontal and vertical holes. However, due to the complex site conditions, the current situation relies heavily on manual labor, making labor-saving at the site a pressing issue. The Multi-Mole method utilizes "TonTon-kun" and "BuruBuru-kun" to mechanize horizontal pushing and vertical excavation. In addition to standalone use, it also allows for the joining of horizontal and vertical operations. The Multi-Mole method significantly improves not only labor-saving but also safety and construction quality.

Danby method

Danby method

Construction is possible only in the work zone on the road without excavation! A new pipeline is formed inside the existing pipe.

The "Danby Method" is a technique for rehabilitating damaged or aging pipes in sewers, agricultural water systems, and sluice gates without excavation. A rigid PVC strip is fed into the existing pipe from a manhole, and while spirally winding it along the inner surface of the pipe, adjacent strips are joined using a fitting component to form a continuous pipe body. After that, using a spacer for injecting filler material, which is pre-installed above the existing pipe, the filler material is injected into the gap between the strip pipe and the existing pipe, resulting in a composite pipe that is integrated with the existing pipe, exhibiting high strength and water tightness. 【Features】 - Construction is possible only in the work zone on the road without excavation. - A new pipeline is formed on the inner surface of the existing pipe. - Improved chemical resistance and abrasion resistance due to the formation of a rigid PVC pipeline. - Enhanced load capacity, seismic resistance, and flow capacity as a composite pipe integrated with the existing pipe. *For more details, please download the PDF or feel free to contact us.*

IPH method

IPH method

Achieving the longevity of concrete structures! Methods for preventing re-deterioration.

The "IPH method" replaces the air present inside the concrete and the injected resin, allowing the resin to diffuse radially from the inside of the drilled holes, thereby filling even the finest cracks at the ends. This method not only enhances the adhesion strength between rebar and concrete but also provides a high anti-corrosion effect, leading to improved durability. It has received technical evaluation from the Japan Society of Civil Engineers. Additionally, structures constructed using this method can extend the intervals between subsequent repairs. Since the deteriorated areas are repaired and injected without being chiseled away, the amount of demolition waste is reduced, resulting in cost savings. 【Features】 ■ High-density filling ■ Rebar anti-corrosion and neutralization suppression ■ Strength recovery and durability enhancement ■ Improved cost-effectiveness and environmental measures *For more details, please download the PDF or feel free to contact us.
