**Soil Bacteria Strong Acidity Countermeasure Method** The "Soil Bacteria Strong Acidity Countermeasure Method" is an effective vegetation technique for slopes containing factors that inhibit vegetation, such as strongly acidic soil (pH ≤ 3). By combining a shielding layer created through soil-cement spraying with a vegetation foundation layer established using soil bacteria methods, it provides stable greening in areas where conventional vegetation has been difficult. **Soil Bacteria Strong Acidity Countermeasure Method System** In the "Soil Bacteria Strong Acidity Countermeasure Method," the vegetation-inhibiting factors present in the ground are shielded by soil-cement spraying, and a vegetation foundation layer is created on its surface. The hard shielding layer formed by soil-cement spraying restricts not only the growth of vegetation roots but also the supply of moisture and nutrients, meaning that the vegetation foundation layer constructed above the shielding layer will largely depend on many of the conditions for plant growth. Taking this into account, the vegetation foundation layer employs a soil bacteria method that possesses self-fertilizing capabilities, eliminating the need for additional fertilization.

The Easy Shelf Method is a simplified spraying framework that can be adopted when it is determined that the conventional site-sprayed framework standards are excessive. It is positioned as a greening foundation work, preventing erosion and surface washout on slopes and embankments, as well as stabilizing the base material. We have recently obtained VE certification from NETIS. (NETIS number: KK-160021-VE) The Easy Shelf Method features a framework that is flexible and easy to construct, allowing for the preservation and restoration of green spaces. The benefits of retaining trees include environmental conservation and the reinforcement effect of tree roots, which can also help prevent avalanches. It is advisable to keep trees such as oaks, chestnuts, and beeches, while it is better to cut down planted cedars, dead trees, and trees with poor vitality. A significant feature is that the framework is a site-cast sprayed framework, using only rebar and metal fasteners (glass stands) for the framework structure, which improves workability and shortens construction time compared to conventional spraying frameworks. 【Features of Glass Stand】 - The punched steel plate structure is strong against deformation from external forces. - Reduces the occurrence of cracks after spraying. - The abundance of openings and cuts eliminates mortar edge separation, making it easy to bind and enhancing workability. - Can be stacked for easy transportation.

The mortar reinforcement fiber mixed spraying proposed by K.F. involves mixing polypropylene fibers for mortar reinforcement, "Balchip MK," with crack suppression polypropylene short fibers, Toughlight RG, and spraying them to further reduce the crack occurrence rate in mortar structures, thereby enhancing durability and reducing lifecycle costs. By performing mixed spraying of reinforcement fibers on slopes and other areas, a more permanent weed prevention effect can be expected. 【Why is the crack occurrence rate reduced?】 Reinforcement fibers have various characteristics depending on their type, each with its own advantages and disadvantages. "Balchip MK" has a long fiber length and a rough texture, allowing the mortar to cling to each fiber, making it difficult to pull out and providing crack prevention effects (cross-linking effect). Additionally, as the bending toughness increases, it is possible to omit the wire mesh and reduce the spraying thickness. However, because each fiber is long and thick, the adhesion area within the mortar becomes smaller.

KEIF, specializing in slope construction methods, presents measures to mitigate wildlife damage to slopes. Q: What about cases that prevent deer intrusion altogether? A: 'Deer Intrusion Prevention Materials for Slopes - Deer Barrier' (Registered with NETIS) In tests conducted in Hiroshima, this method did not allow deer intrusion compared to other methods. Q: What about cases that accept deer intrusion and still maintain a vegetative base after foraging and trampling? A: 'Vegetation Substrate Injection Method - Green Green Mat Method' (Registered with NETIS) By injecting a vegetation substrate into a bag-like injection mat (Green Green Mat) deployed on the slope, a highly stable vegetative base is created. Even if the area is trampled or foraged by deer, the base is protected by the mat, ensuring the slope's protective function is not compromised. Q: What about cases that do not create feeding grounds for deer? A: 'Natural Intrusion Promotion Method - Plant Induction Spraying' This slope greening method uses raw chips to create a solid growth base. It is a slope greening method that awaits the natural arrival of plant seeds. *For more details, please refer to 'Slope Greening Methods: Choosing Techniques Based on the Situation for Wildlife Damage Countermeasures.'

Concrete Canvas (CC) is a composite material developed in the UK that combines concrete and canvas (fabric). It is a cement-encased canvas that sandwiches a specially formulated dry concrete mix between a three-dimensional fiber matrix and a PVC sheet. When laid on the desired surface and sprayed with water or fully submerged in water, the dry concrete begins to harden, allowing for the construction of a thin, highly durable, water-resistant, and fire-resistant concrete surface. **Usage Situations** Concrete Canvas is utilized in various locations, leveraging its unique properties. Waterway construction, erosion prevention (surface protection), dam protection, pipeline protection, design, shelter, three-sided waterway construction (large cross-section), three-sided waterway construction (small cross-section), slope protection works, erosion prevention works, dam protection works, pipeline protection works, pipeline lining works, cable protection works, revetment restoration works, and mine entrance closures (mining development).

The Ministry of Health, Labour and Welfare has revised the safety and health regulations, and Article 539-5 states that there should be a "work plan." This involves conducting and recording a survey of the work site, creating a work plan based on that survey, and informing the relevant workers to carry out the work accordingly. Are measures in place in your work environment to protect important workers from falling objects? Our proposal is the slope safety net "An'ei Net." 【Features】 - Absorbs rockfall energy due to the flexibility of high-strength raschel knitted fabric and the effectiveness of high-strength, high-elasticity rope. - Easily installable on standing trees. - Components are compact, making transportation and installation easy. - Reusable if there are no significant external damages. *For more details, please contact us or download the PDF.

NETIS Registration Number KK-110058-A ■Features of the Flat Cap, a Head Fixing Component for Non-Protruding Lock Bolts 1. Provides a Clean Aesthetic Offers a neat appearance on reinforced slopes. 2. Creates a Safe Environment Prevents damage from falling rocks or contact with vehicles from above the slope. It is safe to use on slopes facing roads as there is no contact with pedestrians or vehicles. 3. Reduces Maintenance Since leaves, driftwood, and debris do not get caught, maintenance work is minimized. 4. Easy Maintenance of Slopes The blades of grass cutters do not come into contact, so they do not obstruct maintenance work on slopes. 5. Economical Conventional reinforcement materials can be used as is, and the number of parts for head treatment is reduced, making it cost-effective. 6. Usable by Anyone There are no restrictions on the installer, so anyone can use it.

The "Rock Bonding Keiwon Bond Method" is a rockfall prevention technique that stabilizes unstable rock masses and boulders by integrating and fixing them to the bedrock using high-strength mortar and adhesive mortar, thereby covering the entire slope for stabilization. This method fills the voids in unstable rock masses caused by cracks in the bedrock and cavities in boulders with the high adhesive strength of Keiwon Bond, eliminating unstable factors by bonding and integrating with the stable bedrock.
