EIA for the proposed Hulhule-Male’ Bridge Project<br />

accuracy will be closely monitored and fixed. Concrete will be poured into the casings to<br />

fix the casing bottom and steel cofferdam.<br />

• A slurry recycling system will be established on the work vessel.<br />

• Drilling machine will use gas-lift reverse circulation technology. A steel reinforcement<br />

cage will be lowered in the casing to create the cast-in-situ piles. After the casing insides<br />

are cleaned, concrete will be poured in.<br />

2.4.1.2 Pier body construction<br />

The pier body is cast-in-site. The construction work covers locating, formwork erection,<br />

reinforcement assembling, concreting and demoulding.<br />

2.4.1.3 Pouring concrete into box girder<br />

Pouring concrete into the box girder of the superstructure will use a cantilever and a basket.<br />

Pouring process of standard girder sections include mobile hanging basket, locating and<br />

formwork erection, reinforcement assembling, concreting, tension of longitudinal and transverse<br />

prestressing tendon and demoulding.<br />

2.4.1.4 Construction of box girder’s closure segment<br />

Construction of box girder’s closure section also uses a hanging basket to cast-in-site. After the<br />

completion of closure the hanging basket shall be removed.<br />

2.4.1.5 Construction of side-span cast-in-site segment<br />

After the closure of each main span, the construction of side-span cast-in-site will be completed.<br />

The construction of side-span cast-in-site segment uses a hanging bracket. The hanging basket<br />

used in the construction shall be replace by hanging bracket when the cantilever reaches the<br />

maximum.<br />

The nose girder shall be set between the transition pier and hanging bracket. Other activities<br />

include formwork erection, reinforcement assembling and the concrete pouring of side-span<br />

cast-in-site segment.<br />
