HULHULE-MALE’ BRIDGE PROJECT

EIA for the proposed Hulhule-Male’ Bridge Project
No. 24 pier is the transition pier of the main bridge, without the pier body. The pier foundation
scheme is planned to use 4 cast-in-place piles with 1.5 m of diameter, and bearing platform is 2.5
m high, with 6.25 (axial direction) × 6.25 m (transverse direction) of plane dimension.
No. 25 and 26 pier bodies are T-type piers, with 2.0 (axial direction) × 4.0 m (transverse
direction) of sectional dimension. The pier foundation scheme is planned to use 4 cast-in-place
piles with 1.5 m of diameter, and bearing platform is 2.5 m high, with 6.25 (axial direction) ×
7.0 m (transverse direction) of plane dimension.
No. 27 abutment of the Airport side shall adopt pier foundation, with 1.5 m of diameter.
2.3.2.5 Design scheme of breakwater
The bridge on the side of airport joins with land via shore-connecting approach embankment
about 115 m in length. A dyke will be constructed around the embankment which will serve as
the breakwater. The core of the breakwater will consist of sand filled geobags, filter cloth and a
rubble cushion layer. The proposed design includes, 0.8 t quadrangle hollow blocks for wave
armour block. The width of approach embankment pavement is 20.3 m with 1:2 for gradient on
both banks. Cast-in-situ concrete anti-billows wall is set on both sides of dyke top. A drain ditch
is set in the rear of wall. The embankment toe (about 5 m wide) will be protected using 150-200
kg apron or rubble and riprap.

2.3.3 Proposed work sites
2.3.3.1 Precast yard at Hulhumale’
The precast yard is a 40,000 m 2 (160 × 250m) area located at the newly reclaimed section of
Hulhumale Island (See Figure 2.10). The site will be mainly used for fabricating I-type beam on
the superstructure of approach bridge. The site includes precast yard area, I-type beam storage
area, reinforcement processing and storage area, steel structure processing area, mixing station,
sandstone stockpiling yard, equipment parking area, materials storage area, power generator
house, parts warehouse, site laboratory, Office and living area and temporary construction wharf.
Major equipment includes gantry crane, generator, mixing station, and wheel type beam carrier
vehicle. Main construction materials and equipment are transported via the sea and unloaded
