Disaster Prevention Wall Construction Method

Disaster Prevention Wall Construction Method

A groundbreaking cantilever retaining wall that withstands sudden heavy rain has been completed.

The "Disaster Prevention Wall Method" is a hybrid retaining wall with a tandem structure. To effectively utilize 100% of the backfill gravel as self-weight, the thickness of the retaining wall is reduced, significantly decreasing the excavation width and volume of excavated soil. Additionally, each tier of the back blocks has drainage and collection functions, allowing any groundwater that emerges from any part of the slope to be drained to the front of the wall, making it a "groundwater discharge type retaining wall." It has also been developed to meet other criteria such as integration through cast-in-place concrete and safe emergency construction responses. 【Features】 ■ Cost-reducing method ■ Groundwater discharge type retaining wall with high drainage functionality ■ Strongly integrated retaining wall ■ Enables safe emergency construction ■ Reduces complaints about backfill gravel settling *For more details, please download the PDF or feel free to contact us.

Recycled Wood Material Method "Kassei Method"

Recycled Wood Material Method "Kassei Method"

Utilizing the natural circulation system to accelerate the decomposition of waste wood and recycle it! Used for compost, vegetation substrate materials, environmental mulching materials, etc.!

The "Kasse-Chip Method" utilizes natural circulation systems to accelerate the decomposition of waste wood and recycle it. During the wood chipping process, "Kasse Liquid" (effective composite microbial material) is added to promote early decomposition (maturation) of the wood, allowing it to be repurposed as compost, vegetation substrate, environmental mulching material, and more, making it a recycling method. 【Features】 ■ Maturation of both coniferous and broadleaf trees in approximately 3 months of accumulation ■ Suppression of greenhouse gas emissions (carbon dioxide and methane) and odor generation ■ No risk of spontaneous combustion due to decay ■ Reduction of on-site costs ■ Improvement of abnormal pH levels ★ Registered with the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System NETIS (No. HR-020017) *For more details, please request materials or view the PDF data available for download.

Reinforcement of Reinforced Concrete Structures: Underwater Applicable CFRP Grid Reinforcement Method

Reinforcement of Reinforced Concrete Structures: Underwater Applicable CFRP Grid Reinforcement Method

It is a method for reinforcing concrete structures in water inexpensively without draining.

The underwater applicable CFRP grid reinforcement method is a technique that provides a cost-effective solution for aging deterioration and insufficient seismic strength in reinforced concrete structures such as bridge piers located underwater. The method involves adhering a lattice of carbon fiber bundles (CFRP grid) that has been impregnated with resin to the surface of the structure using a resin layer that cures underwater, thereby reinforcing the structure. Both the CFRP grid and the underwater curing resin have long-term durability. 【Features】 - Reinforces concrete structures underwater - Can be reinforced inexpensively without drainage - Long-term durability with CFRP grid and underwater curing resin - Carbon fiber can reinforce with high strength and minimal thickness - NETIS registration number KT-100101-A For more details, please contact us or download the catalog.

Unit Network Landslide Prevention Case Study No. 1 | Restoration Measures for Windfall and Slope Collapse

Unit Network Landslide Prevention Case Study No. 1 | Restoration Measures for Windfall and Slope Collapse

This is an example of preventing slope collapse in advance with "Unit Net," which balances slope stabilization and the conservation of the natural environment.

Mikune District, Sayo Town, Sayo County, Hyogo Prefecture ◆ Disaster from Typhoon No. 23 in 2004 In response to the damage caused by Typhoon No. 23 in 2004, the "Unit Net" was adopted at planned locations for the restoration of windfall trees and slope collapse areas, and construction was sequentially ordered based on the plan. ◆ Disaster from Typhoon No. 9 in 2009 While restoration work was progressing sequentially, we were hit by damage from Typhoon No. 9 in 2009. Slope collapses also occurred in surrounding areas, centered around the restoration plan area. There were still unaddressed areas within the restoration plan where slope collapses occurred, but in the adjacent area where the "Unit Net" had been installed, collapses were prevented. There were houses below the slope, but thanks to the installation of the "Unit Net," safety was successfully maintained. ● For more details, please download the materials.

Landslide prevention case study by "Unit Net" 2

Landslide prevention case study by "Unit Net" 2

Conditions during heavy rain disasters at unit net construction sites.

Asakura City, Fukuoka Prefecture, Haki Hoshimaru, Shimizu Moto District From July 5 to 6, 2017, due to the inflow of warm and very humid air towards the stationary rainy front near the Tsushima Strait, a linear precipitation zone was formed and maintained, resulting in extremely heavy rain in the same location. This led to record-breaking rainfall in the northern Kyushu region and caused a heavy rain disaster. In Asakura City, Fukuoka Prefecture, where this heavy rain disaster occurred, unit nets were adopted and constructed in 2014 as part of a steep slope collapse prevention project. You can view the situation near the unit net construction site immediately after the disaster on the Geospatial Information Authority of Japan's YouTube account. The back side of the three-story building (elementary school) shown around 1:40 in the video below is the site where the unit net method was implemented. Despite numerous landslides occurring in the surrounding mountains, the area where the unit net method was applied did not experience any landslides. For more details, please refer to our company's website column and materials (available for download below).
