GUD block construction results
Sakamoto Dam / Annaka City, Gunma Prefecture
Construction in March 2019
We had you lay around two dams which Annaka engineering works office manages.
With an effective storage volume of 50 tons, the dammed water creates the artificial lake "Lake Usui." In order to create the peace of the waterside, an observation deck and a promenade are maintained around it, and Lake Usui is covered with "Yumenose Bridge" and "Homiemi Bridge" to create a beautiful landscape, and part of the lake becomes shallow, You can also enjoy catching fish. Many tourists visit every year.
I was concerned about the environment. Weeds and hills were especially troublesome. I asked a specialist to cut weeds four times each year, but the grass was so thick that I couldn't keep up with it, and it obstructs the promenade. In addition, hills may fall from the branches of trees that rise along the boardwalk.
For this reason, in the summer of 2019, a GUD block was laid on a part of the boardwalk.

“Weed removal is not only labor-intensive, but also expensive, so I tried using GUD blocks for two dams, including the meaning of the experiment. We haven't seen any weeds until January 2, but we are paying attention to the summer season. If we can survive the summer, we will only have a part of the promenade. I would like to consider not only the entire construction but also the construction in other places. Also, there are other civil engineering offices that have the same problems as ours, so I would not be glad if you introduce me. Is not it"
