Sometimes even with the right analysis and studies, things can deviate from the plan. We put attention on those cases because they leave great lessons for us, who build and design structures. We hope you also find this interesting.

完成直後の橋台に沈下や傾きが発生、3カ所でボーリングしたのになぜ?
 高速自動車道の橋梁基礎の建設現場で、鉄筋コンクリート製の橋台の完成直後に、沈下と傾斜の変位が発生した。河谷平野を横断する橋梁の橋台の位置は、右岸側の小さな谷の出口付近に当たる。

As part of the energy transition, renewables and batteries will play a larger roll in any country's energy mix. In Japan they are testing several arrangements to achieve the transition as fast and as smoothly as possible. Civil engineering behind this developments cannot seat idle, we are up to the challenge in KURAKEN to meet the strict requirements of the energy industry.

Today we use satellite based systems like GPS or GNSS, that use radio waves, to locate geographical points in the surface of the Earth. But scientist in Japan have found out that there area also ways to use cosmic rays for this purpose. There are significant advantages to this, for example, cosmic rays can go through miles of stone, so we could locate points even beneath mountains, under the sea or inside deep tunnels. Increasing productivity from science advancements will make us stronger, we will keep on that pathway.



Japanese researchers developed a system based on subatomic particles derived from high-energy cosmic rays to locate a person's position underground, something that existing navigation tools like GPS are unable to do.

Aging infrastructure is becoming a problem in Japan, as many large infrastructure projects were carried out in the 1960s and 1970s. But this is not only a problem for Japan. For example, in Jakarta, the capital city of Indonesia, the increased necessity for groundwater pumping puts in risk the stability of infrastructure. Japan is dedicating satellites and radars to monitor the state of infrastructure in an efficient way. This is an area in which space exploration and civil engineering meet. We must explore the use of those tools to improve our services and productivity.

KURAKEN Caffe News!!



Kajima is a very large construction company and they are implementing automation processes to their construction projects, resulting in CO2 emissions cuts. We, at KURAKEN, are also directing efforts to automation processes in construction. Even though we are a rather small company, we know that the future, and indeed the present, of construction is taking this path.

鹿島が自動化施工システムのCO2抑制効果確認、成瀬ダムで導入のA4CSEL

 鹿島は、秋田県東成瀬村で施工中の成瀬ダム堤体打設工事において、複数の建設機械の自動運転を核とした自動化施工システム「A4CSEL」(クワッドアクセル)による二酸化炭素(CO2)排出量の抑制効果を確認した。自動運転によるまき出し作業で1m3当たりの燃料消費量を有人施工と比べて40~50%削減。その分、建機のCO2排出量を減らせた。

CONSTRUCTION NEWS CAFFE:

Last week there was a big accident in Shizuoka prefecture. During the construction of a bridge over the highway, a beam of about 140 tones fell from about 10 meters high, killing two workers and injuring few more. In construction, safety comes first. Authorities are investigating the causes of the accident in order to prevent this from happening again. We must take all safety measures when working at constriction sites, and that is what we do at KURAKEN.

What are your thoughts about large scale construction accidents?
