About This Product

■``Moving is the mountain's story'' Lock unit (Highly restrained wave-resistant bag type bag material for root protection method)

By adopting a bottom-lift structure, this bag-packed cobblestone has a higher binding force for filling materials compared to conventional bag-filled cobblestones. This product is made to look like a rock by locking the filling material with high binding force. The lock unit has been approved by the Coastal Technology Research Center for verification and evaluation of port-related private technology. ・Compliant with the Ministry of Land, Infrastructure, Transport and Tourism's bag-type root protection bag material performance regulations (long-term performance type) ・Confirmation examination and evaluation of port-related private technology project evaluation technology No. 17004 ・NETIS registration number: QS-200023-A Features

■High filling rate

Since the excess void is almost 0%, movement and movement of the filling material is suppressed.

■High shape retention performance

There is virtually no change in shape during lifting, temporary storage, or installation.

■High durability

Durability and abrasion resistance are improved by using a mesh fabric that is about 4 times thicker (our comparison) compared to conventional bagged cobblestones.

■Can be used in rusty and corrosive environments

It is easy to manufacture and does not require skilled workers. Construction is possible even on slight unevenness.

■Wave resistance properties

The wave stability of the lock unit has been confirmed through hydraulic model experiments.

■Bottom lift structure

The lock unit uses a system (bottom lift structure) in which the filling material is restrained by its own weight.

■Construction procedure

1. Attach the steel material to the special frame. 2. Add filling material. 3. Tie the rope around the mouth. 4. Hanging → temporary storage. 5.Tie the rope again. 6.Complete
