Construction of Tehran (Shariati-Khaje Abdullah) by Pipejacking Method

Project Overview

Tehran Sewerage Pipeline Project started from Shariati Street, Mirdamad Intersection to the south and after passing through Golanbey Street, Ketabi Square and Mojtabaei Street, it ended at the intersection of Shahid Araghi Street on Khawaja Abdollah Ansari Street. The total length of the project according to the contract is 3,982 meters and the total number of manholes is 34, which was implemented using the pipe laying method using micro tunneling devices. The material of the pipelines is polymer concrete with diameters of 1,600 and 1,800 millimeters. To provide the required pipes, Kayson Company has set up a production line in its satellite factories.

During the operations, the Client of the project also notified Kayson Company of the execution of 530 meters of 1,400 millimeter lines located on Mirdamad Street as additional work.
