This month builders increased the concrete tamping 1.9 times as over last month.

The builders have pushed forward with the concrete tamping of the dam on the right bank of Huichon Power Station No. 9.

They applied a rational method as the pillars of the sluice gate went up and registered the peak record in concrete tamping of pillars of the sluice gate by setting up a new system of carrying mixture.

The builders of Huichon Power Station No. 6 created dykes at each interval and carried out draining work, thus fulfilling daily quota of ground concrete tamping more than 2 times.

At the construction site of Huichon Power Station No. 8 ground digging and concrete placing have been done in a short span of time for building fishway reinforcement structure extending dozens of meters.

The workers of the Thaechon Hydroelectric Power Station Construction Company who are in charge of the construction of Huichon Power Station No. 12 produced large steel framework and applied it to the construction to ensure the quality. They also made successes in the concrete tamping of intake floodgate pillars and walls of inlet channels.
