Construction is underway on the Jeju river Sejongbo, Gongju, and Baekje, which were built by the 4 major rivers. The muddy water covers the river due to the construction, and the fish spawning ground is formed in the downstream.
On the 23rd, Daejeon Chungnam Green Union Team leader Kim Sung-jung and Yang Joon-hyeok's secretary visited this place to monitor Geumgang. At 9 am, the water level in the upper stream of Sejongbo was about 1 m lower. At the power station under construction, construction equipment was widespread with the general public blocking access.
Sejong Boss Hydraulic cylinder is being replaced.

When we got inside, we were working on replacing hydraulic cylinders of movable beams opening and closing gates, and removing the gravels accumulated in piping. I went down to the power station side gate. The floor full of mosses was slippery. The soil that was pulled from the piping through the hydraulic hose was piled on one side. Hydraulic cylinders placed for construction work were filled with rust.
To block the oil flowing from the piping being replaced, the adsorber was rolled up and sprayed around. The perishable state of the earth was filled with the pericarp. There was a stench in the place where the soil was piled up. Oil was flowing down on the new pipe. The oil floated on the water.

Sejong Boe, who entered the fourth repair of this year, has been replacing the hydraulic cylinders that open and close the hydrants from the 14th, replacing hydraulic pipes (steel pipes → oil pipes) installed on the wall and floor of the hydroelectric power plant,
Sejong City, which started construction in May 2009, built a budget of 217.7 billion won. The total length is 348m (high information 125m, movable beam 223m), and the amount of water is 425m3, which is 2.8 ~ 4m. The construction was completed on June 20, 2012, and the government awarded Hoon Packaging to Daewoo E & C, a construction company.
However, after five months of completion, the gravels accumulated between the gates and the riverbed were found to be defective by hydraulic devices, and a diver was mobilized in the middle of winter. Every year from February to March, the water gate is opened and checked and maintained. The inspection and maintenance were completed last March. In July, hydraulic cylinder blew up due to hydraulic breakdown and oil leaked. Then, in September, we made another renovation.
Repair work according to Princess Boshu

The princess, suffering from insolvency, is going to be reinforced by next year 's scour (riverbed breaks down by the river) again next year. The lower stream of Kongjubo made a road of hyperspace with nearby soil.
A sheet file (sheet pile) is put on the large heavy equipment at the point where the water-bearing ball and the stone protection ball installed for safety are installed. After that, we will fill in the lost sludge bottom protection ball and pour cement.
In October 2009, a total construction cost of 208.1 billion won was injected into Kongju Bo (length 280m, width 11.5m), which was built by SK E & C. However, due to the discovery of defects such as leaks in detail and leakage of water and the problems of the island, the completion date of construction was delayed several times from December 2011 to April, again June, and July 20 to August 1. Lt; / RTI & gt;
In the winter of 2013, less than a year after completion of construction, Princess Boiling, who had trouble with concrete casting in winter, fell down as if the railing concrete of 280m long and 11.5m wide melted down. A beam leak also occurred. Since then, we have been carrying out reinforcement works every year.
