Pump Capacity : Ф1,000mm x 140cmm x 2.5mH x 1ea
: Ф600mm x 57cmm x 2.1mH x 2ea
Contract Period : 2008. 05. 30 ~ 08. 08
Location : Tongbok-dong, Pyeongtaek-city, Gyeonggi-do, Korea
This project is composed of the two (2) hinged pump gates construction to increase the discharging capacity of the existing conventional pump station and one (1) hinged pump gate application to the existing retarding reservoir at some distance to the above pump station.
identical main river as a downstream.
The building in the middle is the existing pump station. Four (4) outlets with flap valve on the wall
of the pump house continue to play the role of discharging. The existing vertical operation actuators
at the right/ left of the pump house will keep the blind gate open after the completion of this project.
The open/ close function of the flow will be played by the newly installed hinged pump gate. The
two concrete structure for the newly installed pump gate are seen adjoining the main stream.
Hinged gate is connected at the pivot for the swing operation.
Pump is lowered for the mounting on the hinged gate.
Structure for the hinged pump gate is ereted at the retarding reservoir. The existing bank seperating
the retarding reservoir and the main river had only concrete tunnel for the natural flow without gate.
Screen is erected for the safe pump operation at the inlet of the hinged pump gate of the retarding reservoir.
Hydraulic power unit is installed in order to supply the hydraulic power to the cylinder for the open/ close operation of the hinged pump gate as an actuator. 
The side view shows the screen, hinged pump gate and the hydraulic cylinder at the retarding
reservoir.
The above shows the two hinged pump gates at the open position with the existing conventional
pump station in the background.
