Comparison of construction procedures for the "DON'TDIG method" for repairing intrusion prevention fences.

Comparison of construction procedures for the "DON'TDIG method" for repairing intrusion prevention fences.

In the installation work of the support for the setup operation, it is possible to temporarily secure with bolts without filling with mortar!

We would like to introduce a comparison of the construction procedures of the "DON'TDIG method" for repairing intrusion prevention fences with general construction methods. The inspection work of the "DON'TDIG method" only involves checking for cracks or damage in the existing foundation and confirming that there is no rust or cross-sectional loss in the existing posts, eliminating the need for buried cable surveys or investigations of buried cultural heritage areas that are typically required in general methods. Additionally, this method does not require the removal of existing foundations, the installation of posts and wire mesh, or the embedding of steel pipe foundations (L=600mm) into the ground. 【Inspection Work of the DON'TDIG Method】 ■ Check for cracks or damage in the existing foundation ■ Confirm that there is no rust or cross-sectional loss in the existing posts *For more details, please download the PDF or feel free to contact us.

Multi-functional rockfall protection fence 'SPARC Fence'

Multi-functional rockfall protection fence 'SPARC Fence'

Protective fences applicable for rockfalls, avalanches, and landslide debris measures.

The "SPARC Fence" is a slope-installed rockfall protection fence primarily designed to protect roads and houses from falling rocks. It can withstand rockfall energy of up to 318 kJ. Due to its structure, which does not use a damping device, it can also accommodate static loads from snow and collapsed earth. It is effective for rockfall measures in snowy regions and avalanche prevention on slopes with rockfall hazards. Additionally, it can be utilized as a temporary protective fence at construction sites for cut slopes and on weathered slopes. ■ Applicable for rockfall, avalanches, and collapsed earth ■ Supports rockfall energy up to 318 kJ ■ No damping device, resulting in low maintenance frequency ■ Minimal net deformation during rockfall capture Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: HR-130008-A *Registration period has ended *For more details, please download the PDF or feel free to contact us.

Vertical rockfall protection fence "Loop Fence"

Vertical rockfall protection fence "Loop Fence"

A vertical rockfall protection fence with a simple and rational structure to prevent falling rocks onto the road.

The "Loop Fence" is a vertical rockfall protection fence primarily installed along roads to prevent rockfall damage. It can withstand rockfall energy of up to 1506 kJ, making it effective for relatively large-scale rockfall countermeasures. By wrapping wire ropes in a loop between the posts, it reduces the deformation during rockfall capture. Its minimal protrusion towards the road allows for installation close to the roadside. ■ Catches rockfalls on roadsides and slopes ■ Supports rockfall energy up to 1506 kJ ■ Effective for large-scale rockfall countermeasures Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: SK-020001-V *For more details, please download the PDF or feel free to contact us.

High-energy absorption rockfall protection fence "Macro Fence"

High-energy absorption rockfall protection fence "Macro Fence"

High energy absorption type rockfall protection fence with small net deformation during rockfall capture.

The "Macro Fence" is a rockfall protection fence installed on slopes to protect roads and homes from rockfall disasters. It can withstand rockfall energy of up to 5000 kJ, making it effective for large-scale rockfall countermeasures. Due to the small deformation of the net during rockfall capture, it can be placed relatively close to the objects being protected. The deformation amounts of the nets for each type have been confirmed through experiments. By allowing for a configuration that is relatively close to the protected objects, the area required for land acquisition can be minimized, leading to expected cost reductions. ■ Slope-installed protection fence ■ Supports rockfall energy up to 5000 kJ ■ Effective for large-scale rockfall countermeasures ■ Available in five types according to the scale of rockfall Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: HR-090007-A *Registration period has ended *For more details, please download the PDF or feel free to contact us.

Rockfall protection fence "TF Barrier" that is easy to install on existing structures.

Rockfall protection fence "TF Barrier" that is easy to install on existing structures.

The 'TF Barrier' rockfall protection fence, characterized by its "L-shaped" posts, is easy to install on new and existing structures, minimizing the impact on structures during rockfall events.

The TF barrier can be installed on both new and existing structures and can withstand rockfall energy of up to 200 kJ. Since it is designed not to impose a load on the structure, it is possible to address the aging of existing structures, insufficient rockfall capture performance, and inadequate fence height without the need for removal or reinforcement of existing structures. 【Applications】 ● Protection for roads, railways, etc. ● Resolution of insufficient fence height on existing structures ● Resolution of insufficient rockfall capture performance on existing structures 【Features】 ● The support posts are in a 'knee' shape, making installation on structures easy. ● It can accommodate various types of existing structures, such as gravity retaining walls and block retaining walls. ● With two types of special shock-absorbing devices, it is designed to avoid imposing loads on the structure. ● By using two types of nets with different mesh sizes, it enhances the penetration resistance against rockfall. ● Performance has been verified through full-scale experiments.

Rockfall mitigation using flexible structures: "Ring Net Rockfall Protection Fence (RX Type)"

Rockfall mitigation using flexible structures: "Ring Net Rockfall Protection Fence (RX Type)"

During rockfall, a flexible structure rockfall protection fence method that allows for the absorption and dispersion of high energy, with maintenance and management being simple through just component replacement / applicable to railway and sediment control fields.

This is a rockfall protection fence construction method that enables the absorption of high energy up to 3,000 kJ, using a special wire mesh woven in a ring shape (ring net), shock-absorbing components (brake rings) incorporated into the support ropes that suspend the ring net, and wire rope anchors connecting from the top of the support to the ground. 【Applications】 ● Protection for roads, railways, residential areas, public facilities, etc. 【Features】 ● You can choose from six types (RX-025, 075, 100, 150, 200, 300) according to the target energy. ● It is a highly reliable construction method that has obtained construction technology review certification. ● It uses lightweight fence components and has fewer constraints related to the terrain and geological conditions at the installation site, allowing for installation on steep slopes without changing the slope shape. ● It minimizes the amount of tree cutting, and since there is no excavation or concrete pouring on the slope, it reduces the impact on the natural environment and harmonizes with the environment. ● The components that undergo plastic deformation have established replacement criteria, allowing for appropriate maintenance and management after rockfall capture.
