Project No. 17/2021
Project Status as of August 2022
Project Introduction:
The project is located at Macao Peninsula, starting from the sewage pumping station at the north of Alameda Dr. Carlos D'Assumpção along the Avenida da Amizade to the Macao Sewage Treatment Plant. The sewage pipeline will be laid and installed, with a total length of about 2613 meters. The project is divided into three sections, the front open cutting section, the tunnel construction section and the rear open cutting section. The length of the front open cutting section is about 115 meters, and sewage pipes with diameters of 1 and 1.2 meters are installed in the open-cutting ditch of 2.5 meters deep. The tunnel section is about 2,279 meters and the shield construction method is used to install a pressure sewage pipeline with a diameter of 2 meters at a depth of 13 meters underground. And a departure well and an arrival well will be built. In the rear open cutting section, a sewage pipeline with a diameter of 1.5 meters is installed in a ditch of 2.5 meters deep built with open cutting method, and energy dissipation wells and confluence wells will be constructed.
Current Progress:
The project is running on schedule and at present, 47.8% of the total project has been completed. All design work has been completed on schedule, as what should be done at the first working node. And the construction of the departure well has been completed on schedule, as what should be done at the second working node. At present, the shield construction phase is currently underway, as designed at the third working node. Currently, 640 meters of shield construction have been completed. It is planned that the shield construction phase will be completed in January 2023. The excavation and pipeline laying work at the open cutting sections and the construction of energy dissipation wells and confluence wells in the Macao Sewage Plant are currently underway.
