A cost reduction method that effectively utilizes backfill crushed stone as 100% self-weight.
[NETIS SK-060007-A] This is a large block retaining wall made of "backfill material (crushed stone)" filled inside the back of a "large stacking block with a leaning style" that is integrated with cast-in-place concrete. The back of the block is equipped with a corrosion-resistant "back material (expanded metal)," and the backfill material is utilized as self-weight. Traditionally, the backfill material was intended for collecting groundwater behind the retaining wall, but now it can be used not only for drainage purposes but also as 100% self-weight. This allows for a reduction in the cross-section of the concrete part of the retaining wall itself, enabling cost savings.

basic information
This is a cost-reduction method that effectively utilizes backfill crushed stone as part of the block. 【Features】 - A corrosion-resistant backing material (such as steel) is attached to the back of the block, and the backfill crushed stone filled inside is utilized as 100% self-weight. - By using the backfill material not only for groundwater collection but also as self-weight, environmental impact can be reduced. - The length of the "connecting bars" can be adjusted as desired, allowing for an increase or decrease in the self-weight of the backfill material. - The length of the block projection of the retaining wall body can be shortened, making it economically advantageous. - The use of a couple guide pin joint method enhances workability. - Dedicated foundation blocks are also available for the backpack block. - It can also be used in conjunction with the wide wall method. *For other functions and details, please feel free to contact us.
