We Proudly Remember The Passing Of (32) Years Since The Implementation Of The Double-Decker Bridge In The Capital Baghdad
Today marks the thirty-second anniversary of the completion of the double-decker bridge in the beloved capital Baghdad, this bridge that has become an immortal landmark in Baghdad, implemented and completed by engineering and technical cadres from the heroes of (Al-Fao General Establishment) previously and (Al-Fao General Engineering Company) currently and the supporting bodies with it.
This unique achievement in the time of the siege imposed on our country and with the limited and available local capabilities and by purely Iraqi hands (implementation, design and supervision). The Beginning Engineer Ahmed Ismail Majeed, the General Manager of (Al-Fao General Establishment), directly assigned Dr. Tariq Al-Katib to prepare the designs for this project, so Dr. (Al-Katib) submitted the necessary designs for a bridge with three floors and not two floors, as security approvals were not obtained at the time for the third floor, so only two floors were implemented (the third floor was designated for parking lots and casinos). The late engineer Abdul-Aimmah Hassoun Ahmed Al-Majid was assigned to be the project manager. He is one of the competencies and experiences that Al-Fao General Engineering Company is proud of, as he is one of the creative engineers and has a clear imprint in the completion of this bridge. This giant Iraqi project was started on 15/8/1992 and the work was completed in full on 1/12/1993
The Bridge's Leadership Staff
1) Engineer Ahmed Ismail Majeed / General Manager (Al-Fao General Establishment) / the project's implementing agency.
2) The late engineer Zuhair Abbas Mahmoud / General Manager (General Establishment for Industrial Projects) / Supervisor of the bridge's works.
3) The late engineer Abdul-Aimmah Hassoun Ahmed Al-Majid / Project Manager.
4) The late Dr. Tariq Al-Katib / Designer and Head of the Design Team.
5) Dr. Sami Raouf Al-Araji / Director of the Safety and Quality Control Center.
The work in the (double-deck bridge) project was divided into sections that included: -
1 - The Bridged Cycle Approaches
These approaches are divided into (63) spans, the length of each span is (20) meters, ending with a retaining wall with a length of (111) meters, so that the total length of these approaches is (1371) meters, and they are divided into two paths for going and returning, the width of each path is (15) meters. The number of concrete pillars reached (4241) pillars of different types, and the number of precast concrete girders reached (1922) girders, the length of each tributary is (20) meters. These approaches begin to rise gradually and in varying proportions until the incoming path (the cycle side) meets the second floor of the bridge body and the opposite path meets the first floor of the bridge body.
2 - Al-Jadriya Bridge Approaches
These approaches are divided into two slopes, the first slope for descending with a length of (520) meters and the second axis for ascending with a length of (540) meters and a width of (10) meters for each slope. The two slopes meet at axis (7) on two levels so that the descending slope is connected to the second floor and the ascending slope is connected to the first floor. The number of concrete pillars reached (1358) pillars and the number of pre-cast concrete girders reached (555) girders with a length of (20) meters.
3 - Bridge Body
The main bridge body is located above the Tigris River and is (401) meters long, with a single span length of (50.20) meters, resting on (9) main supports, each support containing (18) concrete pillars with a diameter of (1.5) meters and depths ranging between (35-42) meters. The height of the bridge is (19) meters, and the height between the two floors is (5.30) meters, and the width of one floor is (19.5) meters, of which (13) meters are for the car lane and sidewalks (3.25) meters on each side. The span consists of (4) main box bridges, two on each floor with dimensions of (2.5 x 2) meters and a thickness of (50) cm. These bridges are connected vertically with (36) concrete columns for each span and with dimensions of (5.30 x 2 x 0.5) meters. Horizontally with (14) transverse bridges. These bridges are connected with (64) precast secondary bridges.
4 - Earthen Approaches In Al-Dora
These approaches start from the retaining wall area in the course, passing through the intersection of Al-Masafi Street and ending with Aqaba Bin Ghazwan Street, with a total length of (9086) meters and a width ranging from (11-16) meters and an area of (110,000) square meters, where the total asphalt area of the project reached (177,351) square meters.
5 - Concrete Pillars
In order to reduce the project implementation period, five types of concrete piles were used, namely (Bore, Franke, Fabero, tubular, ready-cast). The total number of piles used in the project reached (6474) piles of the above-mentioned types, with a total length of (121) kilometers. These piles were completed in a period of (5) five months.
6 - Roads And Paving
The Roads, Bridges and Airports Department completed the road and paving works on the bridge, and the work included the approaches to Al-Jadriya and Al-Dawra (the two bridges), the bridge body, as well as the dirt approaches from the Al-Dawra side.
7 - Supervision And Quality Control
The Safety and Quality Control Center assumed the tasks of supervision and quality control, as laboratory tests were conducted by the National Center for Construction Laboratories, the Building Research Center, and other laboratories. The number of laboratory tests for the bridge reached (89,460) tests, including specialized tests such as loading tests, destructive and non-destructive tests, tests of pillars, iron supports, and rubber cushions, in addition to regular construction materials tests and concrete tests.
8 - Prefabricated Building Factories
The necessary measures were taken in the prefabricated building factories for the purpose of casting concrete girders, amounting to (2989) girders, as well as pre-cast finishing pieces, numbering (25000) pieces, including (facade cladding pieces, fences, Arab and Islamic facade pieces and concrete sheets).
9 - Alternatives
Due to the unjust siege imposed on our country during that period and the lack of imports, it was necessary to find alternatives for the required materials, which were manufactured locally and with high efficiency, namely (rubber cushions, iron supports and expansion joints).
10 - Initiatives And innovations
- Production of high-specification concrete with a strength of (52 MPa) Mica Pascal.
- Implementation of reinforced concrete piles with a diameter of (1.5) meters and depths ranging between (35-42) meters in the riverbed and implementation of the pile dome above the water level instead of implementing it in the riverbed, which saved time, cost and effort.
- Production of precast concrete pieces in the shape of a bowl placed on the columns for the purpose of implementing transverse bridges without the need for molds and screeds.
- Reliance on precast pieces in the installation process such as girders, fences and facade pieces, which led to shortening the time.
- Using mobile dowels to transport concrete to spans located in the riverbed without the need to build temporary and service bridges with high costs. - Production of cement paints.
11 - Designs
The designs were prepared by the work team in the Department of Roads, Bridges and Airports, which included architectural, structural and mechanical designs, and Dr. Tariq Al-Kateb was at the head of the design team.
