HULHULE-MALE’ BRIDGE PROJECT

Recommendations

Info

EIA for the proposed Hulhule-Male’ Bridge Project The construction technology process of this scheme is presented in Figure 2.15. Underwater topographic survey at pier Integral steel casing + bottom steel cofferdam manufacturing and transportation Floating crane installation Installation of casing and cofferdam Anchor rope distribution and anchorage Anchor rope installation Casing is accurately in-place Installation of winch Removal of winch Fixing bottom steel cofferdam Bored pile construction Removal of anchor Removal of drilling platform Construction of bearing Figure 2.15: Process Flow Diagram for Construction Technology of Integral Steel Casing Platform + Bottom Steel Cofferdam Shallow-water transition pier foundation Construction of transition pier pile foundation will use a steel cofferdam, drilling platform, and rotary driller. The construction technology is as follows: • Steel cofferdam will be transported to the site on barges. A floating crane will place the steel cofferdam on the seabed, install the steel cofferdam top profile and set up the drilling platform. • The floating crane will hoist and place the steel casing in cofferdam. The different sections of the casing will be welded together to form a continuous casing. Alignment Prepared by: CDE Consulting & China Shipping Environment Technology Page| 29
EIA for the proposed Hulhule-Male’ Bridge Project accuracy will be closely monitored and fixed. Concrete will be poured into the casings to fix the casing bottom and steel cofferdam. • A slurry recycling system will be established on the work vessel. • Drilling machine will use gas-lift reverse circulation technology. A steel reinforcement cage will be lowered in the casing to create the cast-in-situ piles. After the casing insides are cleaned, concrete will be poured in. 2.4.1.2 Pier body construction The pier body is cast-in-site. The construction work covers locating, formwork erection, reinforcement assembling, concreting and demoulding. 2.4.1.3 Pouring concrete into box girder Pouring concrete into the box girder of the superstructure will use a cantilever and a basket. Pouring process of standard girder sections include mobile hanging basket, locating and formwork erection, reinforcement assembling, concreting, tension of longitudinal and transverse prestressing tendon and demoulding. 2.4.1.4 Construction of box girder’s closure segment Construction of box girder’s closure section also uses a hanging basket to cast-in-site. After the completion of closure the hanging basket shall be removed. 2.4.1.5 Construction of side-span cast-in-site segment After the closure of each main span, the construction of side-span cast-in-site will be completed. The construction of side-span cast-in-site segment uses a hanging bracket. The hanging basket used in the construction shall be replace by hanging bracket when the cantilever reaches the maximum. The nose girder shall be set between the transition pier and hanging bracket. Other activities include formwork erection, reinforcement assembling and the concrete pouring of side-span cast-in-site segment.
