Large block retaining wall, greening type, green growth retaining wall.

Large block retaining wall, greening type, green growth retaining wall.

Large block masonry retaining wall, greening type - Green growth retaining wall

Unlike other greening blocks, this product does not use backfill crushed stone, which significantly improves workability. At the same time, it prevents the hollowing phenomenon where compost soil and sediment within the block flow out into the backfill crushed stone, as well as the stunted growth and death of trees caused by their roots being obstructed by the backfill crushed stone. 【Features】 - By pouring core concrete, it becomes a masonry retaining wall that can be used up to a standard height of approximately H=5.0m. - By incorporating rebar within the core concrete, it forms a reinforced concrete retaining wall structure with a completely integrated and robust beam, allowing it to be used as a high retaining wall over 5m, capable of withstanding soil pressure, uneven settlement, and earthquakes. ● For other functions and details, please contact us.

[Construction Case] Park Improvement Project *Plans are being distributed

[Construction Case] Park Improvement Project *Plans are being distributed

Access station to a private university! In recent years, the area in front of the station has been developed, resulting in increased foot traffic and considerations for greening!

The project for the development of the JR Minakuchi Station Front Park was carried out. For the large radius (R), type A was used to achieve full greening up to the fourth step, incorporating Green Cup A8 in the product, and using a φ300 drainage pipe at the product joint. For the small radius, type B was used (with some inversion), and a φ300 drainage pipe was utilized for greening. This site effectively showcased the advantages of curved construction, allowing for a beautiful representation of two different radii. 【Project Overview】 ■ Purpose: Development project for JR Minakuchi Station Front Park ■ Construction Method: Box-type retaining wall ■ Large radius used type A, small radius used type B ■ Leveraged the advantages of curved construction to beautifully express two different radii *For more details, please refer to the PDF document or feel free to contact us.

[Construction Case] Road Improvement Works *Plans are being distributed

An essential construction method in areas with high annual rainfall! It is also effective on unstable foundation grounds!

Our company has a track record of road improvement construction. Box-shaped retaining walls, based on various experiments, show that the vertical earth pressure acting on the foundation ground is smaller compared to rigid cantilever retaining walls, similar to the shear stress occurring in the retaining wall, making them advantageous from the perspective of ensuring bearing capacity. Additionally, the structure that acts in a well-balanced manner, as demonstrated in experiments, is effective even on non-stable foundation grounds. In regions with high annual rainfall, box-shaped retaining walls with high drainage performance are an essential construction method. Furthermore, their excellent seismic resistance has been verified through experiments and real phenomena. 【Case Overview】 ■ Purpose: Road improvement construction ■ Method: Box-shaped retaining wall ■ In regions with high annual rainfall, box-shaped retaining walls with high drainage performance are an essential construction method ■ Their excellent seismic resistance has also been verified through experiments and real phenomena *For more details, please refer to the PDF materials or feel free to contact us.

[Construction Example] Restoration of Castle Stone Walls *Blueprints Available

[Construction Example] Restoration of Castle Stone Walls *Blueprints Available

The box-type retaining wall, known for its excellent drainage properties, has been adopted! It also significantly contributes to the planning of the restoration work process!

In the year 2000, during the restoration of the castle walls at Fukuchiyama Castle Park in Kyoto Prefecture following a disaster, Tanba stone was used to restore the historically significant temple-style stone walls, aiming for restoration through traditional civil engineering methods known as Anō-zukuri. A box-type retaining wall was adopted as a combined method that receives earth pressure from the back, excelling in safety, constructability, cost-effectiveness, and drainage. The box-type retaining wall was constructed by stacking using the small step sections of the box, allowing for sufficient securing of installation locations for Tanba stone and workspaces, which greatly contributed to the planning of a safe and swift restoration construction process. [Case Overview] - Purpose: Restore the historically significant temple-style stone walls - Method: Box-type retaining wall - Sufficient securing of installation locations for Tanba stone and workspaces is possible - Greatly contributes to the planning of a safe and swift restoration construction process *For more details, please refer to the PDF document or feel free to contact us.
