Low-pressure resin injection method, Tarpan Type 2 method * Optimal for concrete cracking.

Low-pressure resin injection method, Tarpan Type 2 method * Optimal for concrete cracking.

A low-pressure injection method that achieves a high filling rate that could not be achieved with high-pressure injection methods such as grouting pumps!

The actual internal cracks have a complex shape and are not smooth like acrylic sheets. When injected with a grout pump, the pressure is high, which speeds up the injection time, but considering the filling properties, it is not necessarily true that high pressure is always good. Additionally, there are methods that only involve sealing techniques or applying epoxy to the surface, but these only treat the surface, leaving the internal cracks as they are, which could lead to the widening of cracks in the future or act as a trigger for cracks to develop in other areas. 【Features】 ■ Easy handling of injection equipment! ■ A wide variety of bases! ■ Available in flat bases, corner bases, narrow L-shaped joints for use in tight spaces, and holders, making it adaptable to any site! ■ A trusted product featured in the LPIS (Automatic Low-Pressure Resin Injection Method Guidebook)! *For more details, please download the catalog or contact us directly.

Low-pressure resin injection method Tarpan Type 2 method *Same results regardless of who performs the work!!

Low-pressure resin injection method Tarpan Type 2 method *Same results regardless of who performs the work!!

An automatic low-pressure injection method that eliminates variability caused by the operator by relying on the restoring force of the spring, ensuring the same results regardless of who performs the work!

The actual interior of the cracks has a complex shape and is not smooth like an acrylic plate. When injected with a grouting pump, the pressure is high, which speeds up the injection time, but considering the filling ability, high pressure is not necessarily always good. Additionally, in conventional methods, workers could not leave the site until the injection was completed, but with the automatic low-pressure injection method, once the capsule is set in the crack, the worker can leave the site as the operation relies on the spring's restoring force. This allows for a small number of workers to cover a wide area, and the significant feature of this product is that anyone can achieve the same results regardless of who performs the work. 【Features】 ■Ease of handling injection equipment! ■A wide variety of bases! ■Includes flat bases, corner bases, L-shaped joints for narrow widths, and holders, making it adaptable to any site! ■A trusted product featured in the LPIS (Automatic Low-Pressure Resin Injection Method Guidebook)! *For more details, please download the catalog or contact us directly.

Concrete Repair Method 'IPH Method' for Customers in Aichi Prefecture

Concrete Repair Method 'IPH Method' for Customers in Aichi Prefecture

High-density filling even for fine cracks of 0.01 mm with ultra-low pressure injection while removing air. *Numerous construction achievements within Aichi Prefecture.

At our company, Chūnichi Construction, we are implementing the concrete repair and reinforcement method known as "IPH Method." The conventional concrete repair method, "low-pressure resin injection method," often failed to allow the resin to reach the internal structure of the concrete due to the obstruction of air inside. In contrast, the "IPH Method" allows the injected resin to diffuse radially within the concrete while removing the air present inside the structure, enabling it to fill even the finest cracks at the ends. This detailed filling enhances the adhesion strength between the rebar and concrete, providing anti-corrosion effects as well. We have a significant track record of adoption in tunnels, bridges, and public works projects, and in recent years, there has been a notable increase in inquiries from large private facilities and factories! 【Construction Achievements in Aichi Prefecture (Partial Excerpt)】 ◇ May 2018: Toyoda City, Aichi Prefecture Construction work for seismic reinforcement of the Kanpachi Water Pipe Bridge as part of the Yahagi River Comprehensive Phase II Agricultural Disaster Prevention Project. ◇ March 2019: Okazaki City, Aichi Prefecture Box culvert repair work as part of road disaster prevention construction. ◇ March 2019: Nishikasugai District, Aichi Prefecture Combined construction for the improvement of the internal roads at Nagoya Airport (Phase 5) and civil engineering facilities (Phase 18). *For more details, please refer to the PDF document or feel free to contact us.

[Helpful Materials Provided] Explanation of the 'Void Injection Filling Method' to Prevent Injuries

[Helpful Materials Provided] Explanation of the 'Void Injection Filling Method' to Prevent Injuries

Install PVC pipes for injection! There are advantages such as 'low noise and vibration generation'.

In the "Void Injection Filling Method," if there are depressions or voids around the building, cement is injected to fill them. First, a PVC pipe is installed for injection. Then, a cement slurry is prepared and injected into the void areas. There are advantages such as "possible construction in a short period" and "minimal noise and vibration." 【Process Flow】 (1) Install PVC pipes for injecting cement slurry (2) Prepare the cement slurry for injection (3) Inject the cement slurry into the void areas *For more details, please refer to the PDF document or feel free to contact us.

Introduction of standard construction procedures for obtaining inspection certification for self-supporting manhole rehabilitation methods!

No special materials or construction techniques are required, and it can be completed in a short period of about 4 to 5 days! Here is an introduction to the construction procedure of the SS Hall system!

The "SS Hole System" is a rehabilitation method that simply extends the lifespan of aging manholes. Depending on the conditions, it can be completed in a short construction period of about 4 to 5 days! The construction steps are as follows: 1. Clean and remove the deteriorated sloped walls of the manhole, the vertical walls of the existing manhole, and the invert. 2. Install the "Reinforced Plastic Composite Pipe Manhole" into the existing manhole, filling the gap between the reinforced plastic and the vertical wall of the existing manhole with backfill material. 3. Install the foundation block and slab block of the SS hole, then backfill after installing the sloped walls, adjustment rings, and iron covers to complete the process. 《Construction Technology Examination Certificate (Sewage) obtained March 18, 2021, No. 2021 Scope of application expanded: Manholes No. 1 to No. 4, up to a depth of 10 meters》 *For more details, please refer to the PDF document or feel free to contact us.
