HASUH Pump Gate®, completed in Tongbok-dong, Pyeongtaek-city,Gyeonggi-do, Korea

Project               : Tongbok Pump Station
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.

     The above map shows that the existing pump station and the retarding reservoir  are adjoining the
      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.

HASUH Pump Gate®, completed in Joongma-dong, Gwangyang-city, Jeonnam-do, Korea

Project               : Joongma Pump Station
Pump Capacity  : Ф700mm x 62.4cmm x 2.9mH x 3ea
Contract Period : 2006. 02. 21 ~ 06. 07
Location            : Joongma-dong, Gwangyang-city, Jeonnam-do, Korea

Normally the type of opening/ closing movement of pump gate by actuator is vertical operation. However, if overpass runs next to the pump gate site or the site condition requires the utilization of the space under the vehicle road, the design can not allow the vertical operation of pump gate. In addition, the vertical operation cann't be applied in order to avoid disturbing the skyline to the place where aesthetic appreciation of the landscape is respected.

 

Pivotal swing operation of pump gate can be the best solution to the above difficult cases. As overpass runs next to this Joongma pump station site, the vertical movement of pump gate cann't be applied. Pivotal swing operation by the actuator with hydraulic cylinder was introduced to this project for the first time.

 

                       As overpass runs just next to the pump station site, the vertical operation

                        of pump gate cann't be applied to this project.
 

 

Guide frames are erected at their positions for the civil concrete work.

 

 

Pump test is performed to confirm the discharge capacity at the manufacturer's

                   factory during the factory acceptance test.               

                                          

 

Hydraulic power unit is installed as an actuator to open/ close the pump gate.

 

 

Pump is mounted on the gate leaf before the integrated pump gate is installed.

 

 

         Hydraulic cylinder connects the integrated pump gate and the hydraulic power unit.

        

 

Rotary screen is installed at the inlet of pump gate for the safe pump operation

                   by filtering debris.                                                                                          

 

                                                           

   Flap gate is installed across the road at the downstream in order to prevent 

                       sea water from flowing back into the pump gate system.    

 

                    

Trial operation of pump gate is performed to confirm the smooth operation.

 

 

The side view shows the three sets of hydraulic cylinder connecting the hydraulic  

                power unit and the pump gate.    

                                                                             

 

The front view shows overpass at the left, three sets of rotary screen in the middle

and jib crane at the right.
