IMPROVEMENTS OF AL SHINDAGHA CORRIDOR PHASE 2D - DOUBLE DECK ROAD ON CORNICHE STREET PROJECT commenced on 23rd April 2019 and have completion date by 18th Oct. 2021, is the continuation of the infinity Bridge from Deira side and over Corniche Street and DM Wharfage all the way till they connect with Al Khaleej Street with an approximate length of 1.2 km.
Al Shindagha project bridge is designed with 12 lanes in both directions, with a total width of 53.4m and a total length of 1.8km. The main structure includes 24 continuous girder bridges, of which 3 are cast-in-place structure, the remaining 21 are prefabricated segmental bridges, a total of 1901 segmental beams. The main bridge section has a total of 1170 beams with a width of 13m, and the ramp bridge section has a total of 731 beams with a width of 8.2m to 11.7m; the structural forms are all semi-cantilever and semi-span-by-span composite systems.
Different from the traditional bridge construction method, the short-line method precast segmental construction technology, and the precast construction technology adopts a new model of green construction, intelligent construction and standardized construction. Industrialize the traditional construction projects to improve production efficiency and construction quality. This project uses bridge launching gantry for the assembly and erection of bridge segments. Its advanced technology, economical rationality, and standardization of production flow have greatly promoted the level of local construction industrialization in the UAE and set an example for green construction and green development.
This method with line control technology, short-line method segment precast technology, segment erection technology, cast-in-place wet joint construction technology, bridge launching gantry technology, temporary prestressing design and construction technology and organizational design are controlled, and all aspects of the project are closely linked With the cooperation, a single construction record was created in which a single mold bed prefabricated a segment in 1.0 days, and a bridge launching gantry erected a span bridge in 2.5 days.
The erection by launching gantries reduces material waste by 25%, construction waste by 70% and energy consumption by 55% during the construction process. The pollution such as noise and dust is also significantly reduced, and the impact on the surrounding environment is greatly reduced. The advanced construction technology greatly reduces the construction risk of bridge construction. we actively develop and promote green technologies, continue to innovate on the premise of ensuring production quality, and promote the production concept of resource saving, low-carbon and environmental protection.
The implementation of this construction method has been recognized and praised by the client (Dubai Road Transport Authority RTA), the consultant (Parsons) and all sectors of society. The construction technology has attracted attention in the industry and brought good social and economic benefits.
