Notice of Participation in the Construction Technology Fair 2025 in Chubu from December 4 (Thursday) to December 5 (Friday), 2025

Utilize existing rockfall protection fences as they are! We will introduce various construction examples with accompanying photos.

This document introduces examples of the "Stronger Method" construction. This method allows for the reinforcement and height increase of existing rockfall protection fences without special processing, utilizing them as they are. Various construction examples conducted nationwide are presented with accompanying photographs. 【Examples Listed (Excerpt)】 ■ Partial height increase type: Fence height H = 2.0 → 3.0, Construction length L = 22.9m ■ Partial height increase type: Fence height H = 1.5 → 3.0, Construction length L = 42.7m ■ Partial height increase type: Fence height H = 1.5 → 4.0, Construction length L = 35.9m ■ Partial height increase type: Fence height H = 2.0 → 3.0, Construction length L = 21.0m ■ Partial height increase type: Fence height H = 1.5 → 3.0, Construction length L = 12.0m *For more details, please refer to the PDF document or feel free to contact us.

• Renovation and repair methods

The construction period is one day! The cost is less than half compared to base plate type or when demolishing and rebuilding.

Our company offers a rockfall protection fence reinforcement method called "Stronger Method," which allows for the reuse of bent posts by utilizing existing structures. First, remove the wire attachment fittings and cut the post at the base (250mm from the top). Then, attach the post connection member (only bolted). Next, install the raised post and reattach the removed wire attachment fittings. Compared to base plate systems or complete demolition and new installation, the cost is less than half, and the construction period can be completed in one day. [Example of Adoption] ■ Location: Yamanashi Prefecture ■ Type: Raised type ■ Work Procedure 1. Remove the wire attachment fittings and cut the post at the base (250mm from the top). 2. Attach the post connection member (only bolted). 3. Install the raised post and reattach the removed wire attachment fittings. *For more details, please refer to the PDF document or feel free to contact us.

Change the height from 2m to 3m! This method allows for approximately half the cost and a significant reduction in construction time.

We would like to introduce an example of the "Stronger Method," a rockfall protection fence reinforcement project that utilizes existing structures in Yamanashi Prefecture. There were instances of rockfalls exceeding the fence, and there was a desire to increase the height of the fence. Additionally, although a high-energy protection fence had already been designed, it was costly. There were also bent posts that the client wanted to reuse if possible, which led to the adoption of this method. The height was changed from 2m to 3m using a raising type to meet the desired fence height. Furthermore, this method allows for approximately half the cost and significant shortening of the construction period. Regarding the bent posts, part of the base of the posts was retained and raised to accommodate the situation. 【Adoption Example】 ■ Location: Yamanashi Prefecture ■ Type: Raising Type ■ Reasons for Adoption - There were rockfalls exceeding the fence, and there was a desire to increase the fence height. → Addressed with the raising type (H=2.0→3.0m) - A high-energy protection fence had already been designed, but it was costly. → Approximately half the cost and significant shortening of the construction period. - There were bent posts that the client wanted to reuse. → Raised by retaining part of the base of the posts. *For more details, please refer to the PDF materials or feel free to contact us.

• Rockfall prevention agent

Change the height from 1.5m to 2.5m with a raised type to accommodate your desired fence height.

We would like to introduce an example of the "Stronger Method," which is a reinforcement work for rockfall protection fences utilizing existing structures in Fukushima Prefecture. There were rockfalls that exceeded the fence, and there was a desire to increase the height of the fence. Additionally, it was adopted with consideration for the landscape and to accommodate landscape colors. The height was changed from 1.5m to 2.5m using a raised type to meet the desired fence height. Furthermore, we were able to accommodate landscape colors with hot-dip galvanized coating plus painting. 【Adoption Example】 ■ Location: Fukushima Prefecture ■ Type: Raised type ■ Reasons for Adoption - There were rockfalls that exceeded the fence, and there was a desire to increase the height of the fence. → Addressed with a raised type (H = 1.5m to 2.5m) - There was a desire to accommodate landscape colors with consideration for the landscape. → Possible to accommodate with hot-dip galvanizing plus painting. *For more details, please refer to the PDF materials or feel free to contact us.

Examples of adopting reinforcement works for rockfall protection fences utilizing existing structures are published!

This document introduces examples of the "Stronger Method," a reinforcement technique for rockfall protection fences that utilizes existing structures. It includes a case from Fukushima Prefecture that addressed the request to raise the fence height due to rockfalls over the fence (from H=1.5m to 2.5m) with a raised type, as well as a case that dealt with the desire to reuse bent posts. In addition to detailed reasons for adoption, the document includes before-and-after photos, making it easy to compare the conditions before and after construction. [Contents] ■ Adoption examples (Fukushima Prefecture) ■ Adoption examples (Yamanashi Prefecture) ■ Replacement of bent posts is possible! *For more details, please refer to the PDF document or feel free to contact us.

• Protective fence

Utilizing existing rockfall protection fences! Achieving both short construction periods and low costs without the need for special equipment. Proven results in railways and other applications.

The "Stronger Method" is a rockfall countermeasure technique that allows for reinforcement and heightening of existing rockfall protection fences without processing or dismantling them. No special equipment or skills are required, and it can be completed in just a few days. It enhances rockfall capture performance with "short construction periods and low costs." It is compatible with H-beam type protection fences and has been widely adopted in railways and highways. Currently, we are offering a collection of case studies for construction near railways. 【Features】 ■ Construction costs are lower compared to new installation of protection fences ■ Can be constructed without special equipment such as heavy machinery ■ Short construction periods allow for brief traffic restrictions ■ Achieved reinforcement of approximately 30 meters of protection fence in 3 days ■ NETIS registered method (Number: HR-140004-A) *Catalogs and case study collections can be viewed via "PDF Download."

Easily, cheaply, and quickly raise the height of the existing stone guard! [Check the easy installation in the video]

We are currently offering a catalog featuring case studies of the Stronger Method, which has been adopted by the Ministry of Land, Infrastructure, Transport and Tourism! For more details, please download it. The Stronger Method is a completely new rockfall countermeasure technique that utilizes existing rockfall protection fences without any special processing, allowing for reinforcement and an increase in fence height. It can raise the fence height "easily, inexpensively, and in a short period," and the rockfall capture performance is more than doubled! It is compatible with both new and existing H-beam type rockfall protection fences. Adoption Case (Ministry of Land, Infrastructure, Transport and Tourism) ● Initially planned to "break down the retaining wall → new construction," but wanted to minimize damage to the retaining wall as it had been repaired multiple times. 　→ No need for any demolition (or core drilling) of the retaining wall concrete. ● As it is a major national road, we wanted to shorten the traffic regulation period. 　→ Only one day of regulation during material delivery (normally, regulations last about two weeks). ● We wanted to utilize existing stock and reduce costs. 　→ No processing required for existing structures, resulting in about a 20% cost reduction compared to new construction. *For more details about the case studies, please contact us or download the catalog to view.
