It is widely adopted as a safety measure for roads and railways running through mountainous areas across the country!
An evolved form of rockfall prevention works! Introducing environmentally adaptive rockfall prevention measures that can respond to various ground conditions!
Efficiently absorbs falling rock energy with flexible wire ropes and steel supports!
Excellent workability and easy maintenance! An economical and versatile rockfall protection method that preserves the rich natural environment as it is.
By adopting a new type of anchor, we will shorten the suspension rope and significantly reduce the construction area!
The beauty of nature, just as it is. Thinning and logging of mixed woods and plantations can be done with minimal impact.
Construction evaluation improvement! Easy installation! Metal spacer for spraying 'CK Spacer'
Order from the Hata Civil Engineering Office in Kochi Prefecture! Case study on rockfall countermeasures and prevention.
Since there is no extensive excavation, the ground will not be damaged! Even at high slopes, construction can be easily carried out.
Sheath pipe structure! The support is installed in a sheath pipe style within the steel pipe pile, which provides excellent workability.
The upper and lower members are connected by spherical washers, creating a structure that does not transmit bending stress!
It applies to rock slopes with the risk of floating stones and rolling stones!
Install thick wire mesh as a supporting material to prevent the erosion of accumulated soil and gravel!
Both early greening with pre-introduced seeds and greening through natural invasion without using seeds, considering the ecosystem, are possible!
A new component has emerged that can reduce the acquisition of land for rope laying projects!
A rockfall protection fence that uses anchor foundations for fixing the posts, allowing the posts to be installed directly into the ground!
It minimizes the felling of standing trees on slopes and excels in protecting natural landscapes!
A structure that prevents falling rocks by securing floating stones and rolling stones with wire mesh and wire ropes!
A structure that uses H-shaped pillars at the top of the wire mesh to install an opening, allowing falling rocks from the upper source to drop inside the wire mesh.
The soil consists of gravelly soil, rock blocks, and pebbles, with examples of rockfall countermeasures and preventive works within an area of 850m2!
Examples of rockfall countermeasures and preventive works in a 1,300m2 area of clay, rock masses, and cobblestone soil!
Case study of rockfall prevention and mitigation works in a 250m2 area of rock and gravel soil!
The soil type is clayey soil, rock masses, and pebbles, with examples of restoration work in a 250m² area!
The soil type is gravelly soil, and it is an example of rockfall countermeasures and preventive construction within a range of 1,500 m²!
Examples of rockfall countermeasures and preventive works in a 200m² area with soil consisting of rock masses and gravel!
No need for concrete foundations; installation can be done on-site! Example from February 2013.
Case study using Ribmat Green R-20! Conducted in October 2019 (R1).
Application for rockfall countermeasures and prevention, case from October 2022 (R4), quantity 3,500 m².
The construction site in February 2021 (R3) is an example from Shizuoka Prefecture! The quantity is 1,150 m².
A method of preventing falling rocks within a wire mesh by securing floating stones and rolling stones with wire mesh and wire ropes!
No need for large machinery! Examples of construction methods that do not require large or specialized machinery.
A wire rope net is installed tightly against the slope! It suppresses the initial movement of loose stones and floating rocks, preventing them from becoming falling rocks.
We protect the slopes with a hybrid construction method that stabilizes scattered boulders and floating stones while also providing erosion prevention and landscape restoration functions!
Change the height from 1.5m to 2.5m with a raised type to accommodate your desired fence height.
Change the height from 2m to 3m! This method allows for approximately half the cost and a significant reduction in construction time.
The construction period is one day! The cost is less than half compared to base plate type or when demolishing and rebuilding.
The falling rocks do not directly collide with the support pillars or suspension ropes, but instead absorb the falling rock energy solely with the curtain section, which is an elastic material!
Stabilization of slopes and promotion of greening. Significant effects on natural restoration while preventing falling rocks!
It is possible to construct without affecting the surrounding ground! A highly reliable anchor.
You can achieve the strength that could only be secured through large-scale construction with a simple construction method!
Introducing the next-generation pipe anchor that can be installed on high-quality ground without relying on surface N values!
Construction can be easily completed in a short period of time with small, lightweight specialized tools! We have two types available.
Prevents landslides in unstable strata without damaging the natural landscape!
Due to the low output volume, the distance from the preservation target can be reduced!
To maintain construction methods more safely, it is necessary to select according to site conditions and construction methods!
Add energy absorption to conventional construction methods! The collision surface is reinforced to prevent rockfalls.
Strong against salt! Strong against acid! Strong against ultraviolet rays! It is a low-density polyethylene coated wire that does not rust.
For double-sided fences and rockfall prevention nets. Crimped diamond wire mesh.
Supporting everyone's lives in unseen ways. Rockfall prevention wire mesh and wire mesh for rockfall protection fences.
Introduction of the site investigation records for the construction results of rockfall prevention works that bond rockfall sources.
