KRUŠIK SPIRAL MANHOLE                                                        serbian

TYPE-1- Manhole for installation in groundwater

sahta-za-kanalizacijuThe height of the manhole is higher then the level of groundwater. Size of the concrete weight device are determined according to the downforce of the water. This type of manhole is designed for pipes from 300 to 800 mm. Changing the direction of the pipeline is done in the manhole.                                                                                                                                 

 

 

 

 

 

 

 

 

 

TYPE-2- Manhole for installation in ground without groundwater

sahta-za-kanalizacijuThe height of the manhole is 400 mm larger than the diameter of the pipeline. This type of manhole is designed for pipes from 300 to 800 mm. Changing the direction of the pipeline is done in the manhole.                      

 







 

 

 

 

TYPE-3- Tangential manhole

sahta-za-kanalizacijuThis type of manhole is designed for big diameters of the pipeline, from 900 to 3000 mm. Changing the direction of the pipeline is made by arch. This manhole is lowered in the trench in one piece and it’s placed into the concrete foundation.                               

 

 

 

 

 

 

 

 

 

 

TYPE-4- Manhole with anchor teeth

sahta-za-kanalizacijuThis type of manhole is combination of concrete manhole which carry static loads and coverings made of PEHD which are intended for watertightness. Coverings are with anchor teeths. This type of manhole is intended for big loads with hight level of groundwater. Manhole is intended for pipes with diameter from 300 to 800 mm. Changig the direction of the pipeline is done in the manhole.
