River maintenance work

       River maintenance work is work for flood control, flood countermeasures, environmental conservation, disaster recovery, etc. While rivers are widely used in daily life as waterways, fishing grounds, and places for people to relax, disasters caused by heavy rains do not follow. We are in charge of excavating the riverbed and reinforcing the revetment to prevent flooding. With the technology to perform construction from the water, it can be constructed even if a work place is not secured on land.

Sumida River (upstream  and downstream of  Ryogoku Bridge) Seismic retrofitting  of the            right  bank tide embankment

Ordering party:
Koto Waterworks  Office
                    
     Seismic retrofitting of the tide embankment under the Ryogoku Bridge over the Sumida River and maintenance of the terrace,which is a waterside walking path, were carried out.
     In the seismic retrofitting work of the seawall, 146 steel sheet piles for 16 m will be placed. However, the girder bridge of Ryogoku Bridge is only 4.5m below.
    Since it cannot be cast once, it was constructed while welding short steel sheet piles. Moreover, welding was done in the summer, and we finished it while fighting against the heat of welding and temperature.
      There are also rest areas, benches, and flower beds on the waterside walking path where the terrace has been maintained.
      It seems to be a running and walking course for local residents, and it is also used as a place of relaxation.

Tokyo Daiichi ConstructionOffice                                                        
      I was in charge of the Furukawa River Improvement Project near Minami Azabu, Minato Ward. Furukawa has been flooded by torrential rain, and the construction is highly requested by the locals.
    Since it is difficult to secure a work space with the Metropolitan Expressway in the sky and houses on both banks, we adopted the gyro method with a small working radius.
      This construction for the purpose of preventing river flooding will continue to be maintained.

Port maintenance work

       Port maintenance work is work carried out for the purpose of maintaining the environment of the entire port. There are mainly pier construction, breakwater construction, route dredging, and seismic revetment construction.

Excellent construction

First year of Reiwa Construction Bureau Excellent Construction Award Ceremony

      July 10, 1945: Received an excellent construction commendation from the Director of the Tokyo Metropolitan Government Bureau of Construction.

       From the construction projects completed within the Construction Bureau in 2018, the "Nomigawa tide embankment seismic retrofitting work (No. 14)" constructed by Minato Civil was selected as an excellent work. This work was to reinforce the earthquake resistance of the seawall to prevent flood damage caused by tsunamis when the largest earthquake occurs in the future.
In Nomigawa, the width of the river is narrow and the houses are adjacent to the seawall, so Yamanaka, who is in charge of securing work space, considered the minimum necessary materials and equipment and deployed all of them on the river. It was highly evaluated that the construction was completed without delay by utilizing such a pontoon.
Mr. Takashi Miura said, "It will be a model for the future to complete the construction within the deadline while making ingenuity in the severe construction situation. It was an excellent construction including quality control and workmanship." I got the words.
