ITA rewards underground construction projects around the world
The global pandemic has recently brought to light the importance of space, especially in urban areas. How do you plan city life if people have to stand within 1 meter of each other? On the contrary, can the global megalopolis provide all of its population with sufficient electricity and water while people live in long-term lockdown due to the global pandemic? In addition to the global demographic growth of the last decades and the challenges encountered in housing, the urgency to find new solutions to free up surface space is more present than ever. This urgency is one more reason for international decision-makers to pursue town planning to free up surface space.
Since 2015, the International Tunneling and Underground Space Association has been organizing the ITA Tunneling Awards, which aim to reward the most revolutionary innovations and exceptional projects in the field of tunnels and the use of underground space. The next edition will be a virtual event to be held on December 3 and 4, 2020.
Although megaprojects are being undertaken all over the world, the category âInnovative and Contributing Underground Spaceâ underlines the importance of underground space as a dedicated space that must be invested as a link between airspace and space. underground. This will allow businesses to build resilient and sustainable urban areas.
The following projects are recognized by ITA:
Indian Strategic Oil Reserves Padur, India
Energy security is one of the most difficult issues faced by Indian public authorities. The Indian government has entrusted the Indian Strategic Petroleum Reserves Limited (ISPRL) with the construction of an underground storage facility for crude oil. This project is innovative because it highlights the importance of the coexistence between air and underground spaces.
The facilities provide the safest and most secure means of storing crude oil for longer periods, as the product is stored at a depth of 80 meters below the earth’s surface. The above ground part of the installation requires less space and the available land can be used to create other renewable energy projects, such as solar power plants. In addition, the facility can exist without disturbing the natural green environment. The total length of the tunnel to create the underground caverns was about 30 kilometers with an excavation of about 22 million tons of hard rock.
Shenzhen Chegongmiao Integrated Traffic Hub Project, China
Shenzhen Chegongmiao Integrated Traffic Hub Project is a huge multi-functional job. It includes construction of new metro interchange station, improvement of Xiangmihu roads, works on municipal auxiliary, development of underground space and airspace for land saving functions. . In addition, its scope includes underground metro stations, business development, underpasses, ground roads, bridge renovation and other categories.
The project facilitated the traffic functions of Xiangmihu and Shennan avenues, improved the surrounding pedestrian system and traffic connection facilities, implemented the separation of people and vehicles, and comprehensively improved traffic and distribution capacity. In the region. This was done by renovating the Chegongmiao and Xiangmihu interchange while carrying out the construction of the metro.
Union Square Market Street Station – Drilled wells as permanent ground support, United States
Union Square Market Street (UMS) station is a subway station under construction as part of the central subway project in San Francisco.
The whole project is a 1.7 mile long subway extension with three underground stations and one surface station. The project will improve public transportation by extending the third line of the Muni-T subway through the market district, Union Square and Chinatown.
The south entrance will be integrated with the existing Bart and Muni Powell Street station while providing a direct connection between the two transit lines.
To the north, the main entrance will be at the southeast corner of Union Square on Geary Street. Part of the famous Union Square Garage and Plaza will be redeveloped to house the main evacuation points, as well as two emergency ventilation shafts. The station is approximately 950 feet long. Its overall configuration is divided into three areas: the north hall, the platform and the south hall. The North Concourse is approximately 200 feet long and 55 feet below the pavement. The platform is approximately 400 feet long and its depth ranges from 90 feet to 100 feet. The South Concourse is approximately 250 feet along Stockton Street and another 100 feet as it winds along Ellis Street. The depth varies from about 20 to 30 feet as it rises north.
