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.

HASUH Pump Gate®, completed in Gimhae-city, Gyeongnam-do, Korea

Project               : Andong Pump Station
Pump Capacity  : Ф1,350mm x 240cmm x 5mH x 5ea
                           : Ф1,000mm x 120cmm x 5mH x 1ea
Contract Period : 2007. 08. 30 ~ 2009. 02. 20
Location            : Bulam-dong, Ghimhae-city, Gyeongnam-do, Korea

                           Concrete form is attached to the guide frame set prior to the concrete
                           pouring in order to provide the pump gate with a vertical movement
                           way on which rollers on both sides run.





Actuator is installed at the top of the test bench to show its lifting capacity
during the factory acceptance test.                                                             
 
 
Submersible pump is now under the performance test at the manufacturer's
                      factory during the factory acceptance test.       
                                             
 
         Roller gate is lifted for the installation on the guide frame after the main       
structure is made.                                                                                  
 
 
   Pump is lowered in order to be mounted on the roller gate.      
 
 
Actuator is lowered to be positioned on the base frame.
 
 
Rotary screen is installed in order to guarantee the safe pump operation
by filtering the debris at the inlet flow to the pump.                  
           
 
Civil work is made for the floor at the outlet drainage way.

HASUH Pump Gate®, completed in Kapuk Poglar, Jakarta, Indonesia

Project               : Pembangunan Pump Gate Project
Pump Capacity  : Ф700mm x 60cmm x 4.2mH x 6ea
Contract Period : 2010. 08. 30 ~ 11. 30
Location            : Kapuk Poglar, Jakarta, Indonesia

                    Jakarta has been suffered from flooding due to the low-lying area. It is severe
                    when sea level rises as high tide. River is unable to drain to the sea even in the
                    sunny days.






                        This project is planned at the existing station equipped with blind gates
                         without pumps.Thus the existing structure above ground shall be
                         demolished for the new structure building.


                        The existing lower structure is partially revamped for the new roller gates.


                              Bottom beam is erected at its position as part of the guide frame.


                                Side beam and upper beam are erected to form a guide frame.


                              Our general manager YongHyun Kim is dispatched to supervise
                               local construction work at the site.


                         Spindle is connected between the actuator and the pump gate assembly
                         to show the actuator's capability to lift the assembly at the test bench for
                         Factory Acceptance Test at Hasuh factory.


                       The actuator is installed at the top of the test bench for Factory Acceptance
                        Test at Hasuh factory.



                         Inspectors from Local Authority watch the pump gate assembly lifted
                         at the actuator test bench for Factory Acceptance Test.


                        Pump test is performed for Factory Acceptance Test at pump manufacturing
                          shop.


                                     Pump gate is installed at the newly revamped structure.


                               Actuator and local control panel are installed at the newly built
                                control room.


                           The yellow-colored room at the top is for the actuators and the local
                            control panels.


                            Director SeongGwi Kang is dispatched for the supervision prior to
                             pre-commissioning.


                                     Pump gate is lifted for the pre-commissiong at the site.


                         Public officers from Local Authority attend the pre-commissioning for
                          the inspections.


                              The view from the top shows the upstreams along with the clean
                               street after the completion of the construction project.


                                 The above shows the front view of the pump gate facilities.
