construction

process of the acropod dam at Surveyor has been an important task given the challenging coastal environment and the need to protect the city from powerful sea storms. The design of the Sir Bear Dam is based on the use of acropods, a type of concrete block commonly used along the Mediterranean coast. However, the new generation of acropods used on the surface allows for easier and faster installation. The construction process involves collecting rocks and dispersed materials from the sea, sorting them according to different sizes, and reintegrating them into the dam.

Both terrestrial and maritime rock excavation techniques are used to anchor the future acropods and prey to the seabed. Anchor depths vary from 2 to 8 meters and the process lasts approximately two months at the prefabrication site activity is at its peak the concrete plant produces 150 cubic meters of concrete per day in around 15 to 20 workers participate in The prefabrication process The acropods used in the project are the most recent generation that weigh 5 tons each and measure approximately three meters high and wide, they have been molded and welded by the Tunisian company Seas Comets, specialists in this field. It is the first time that the latest generation of acropods has been manufactured and installed in France. making the surveyor project a pioneering effort here acropogos are produced when the concrete reaches the required hardness the mold is removed the acropogos blocks will be transported to the landfill after the acropogos have gone through a 21 day drying period they are ready to be The Sir Bear Dam structure was transported and installed to handle the heavy acropods using a powerful 200 ton crane.

This crane is not only capable of lifting massive blocks but is also equipped with GPS guidance technology to ensure accurate positioning. The GPS system helps the crane operator to precisely position the acropods according to a predefined plan, ensuring that they are correctly aligned and fit perfectly into the overall structure of the dam. However, the installation process requires more than just the experience of the crane operator. Divers play a vital role in assisting the crane operator during placement. of the acropods, divers work in coordination with the crane operator, providing visual guidance and ensuring that the blocks are precisely placed according to the predetermined plan.

Most of the materials used in construction, including rocks and aggregates, come from the remains of the old dam. however, additional supplies of rock are obtained from quarries to meet the required quantities. In total, approximately 32,000 cubic meters of rock have been dredged and placed with rock blocks weighing between 1 and 10 tons. A combination of sea and land transportation methods have been employed to transport and place a total of 70,162 acropod blocks and 400 slotted cubic blocks. During the construction of the survey dam a significant amount of concrete was used for the capping wall and keystones. For a total of three thousand cubic meters, this significant amount of concrete was necessary to ensure the structural integrity and stability of these key components of the dam.

The crown wall serves as a protective barrier against the force of the sea, while the keystones provide additional support and functionality for the overall infrastructure. Once the main construction phases are completed, the focus shifts to the final stage. of the ongoing project, this phase involves the precise placement of the remaining acropos blocks using specialized self-propelled cranes. These cranes are meticulously operated to ensure precise alignment and positioning of the blocks. The purpose of these final acropods is to safely connect and integrate existing acropods. With the crowning wall, the completed topographic dam has a length of 110 meters, a height of 4 meters, a promenade of 6.20 meters wide and a depth of 12 meters.

The production of wave dissipating blocks commonly known as tetrapods involves several stages to ensure high quality manufacturing. and durable structures that effectively dissipate wave energy. This section shows an overview of the production process. Assembly of three pieces that form shapes. In this step, three shape-forming pieces are brought together and assembled in a specific configuration to create the mold for the tetrapod. These pieces are designed to give the tetrapod its characteristic shape pouring the concrete mixture once the pieces that form the shape are assembled a concrete mixture is prepared according to the required specifications the concrete mixture is generally a combination of cement Aggregates such as sand and gravel water and sometimes additives the mixture is carefully poured into the mold formed by the pieces that form the shape, the mixed concrete is compacted with a vibrator to ensure that the concrete mixture fills the mold evenly and removes any air pocket or gap.

A vibrator is used, the vibrator is inserted into the concrete mixture and its vibrations help to compact the mixture improving its density and strength. The compaction process also helps to eliminate trapped air bubbles. All connections are airtight. Air leaks are excluded. After compacting the concrete mix the tetrapod is carefully inspected to ensure all connections are tight any potential leaks in the concrete mix are checked and addressed, ensuring the tetrapod is properly formed and structurally sound. foreign curing and release after pouring and vibrating, filled molds are left undisturbed to allow the concrete to cure and gain strength.

The curing process is crucial to the development of durability and structural integrity of tetrapods typically takes several days or weeks depending on the specific concrete mix and curing conditions. Once the tetrapods have reached sufficient strength, the molds are dismantled and the blocks are unmolded. Careful handling is necessary to avoid any damage to the tetrapods. Newly formed tetrapods During this quality control and finishing stage, each tetrapod is inspected for defects or imperfections. Quality control measures ensure that finished blocks meet required standards and specifications. At this stage any necessary repairs or adjustments are made. Tetrapods can also be surfaced.

Treatments such as sandblasting to improve its resistance to erosion and enhance its appearance. Kaisen technology has revolutionized the construction of port infrastructure. It offers a wide range of design possibilities, making it suitable for various marine structures, such as vertical key docks. Maritime containers. Offshore foundations. Mooring dolphins. and marine stations this versatility allows for innovative solutions and even the simultaneous construction of docks and cays providing a mixed approach compared to traditional

options essentially a kaisen is a concrete and steel structure that provides rigidity and stability to marine structures asiona infrastructure leader in the field with more than 100 years of experience has built the largest reinforced concrete Kyson in the

world

measuring 66.5 meters long, 24.6 meters wide and 34 meters high the first step in building a Kyson is the preparation of a reinforced concrete floor, a raft with steel rods is introduced to reinforce the pier floor of the kaisen building.

This floor served as the base for the entire structure. Once the floor is in place, the next step is to lower the structure that suspends the formwork and then attaches the formwork which is a temporary mold or casing as it slides down, this formwork will contain the concrete during the pouring process with the formwork in position, the concrete is poured into the kaisin . It is important to ensure that the concrete is properly mixed and of high quality to ensure the strength and durability of the kaisen. The concrete is allowed to set and harden once the Kyson is completed, the formwork is removed and the kaisen is left ready for further construction or deployment to anchor and support the casings.

Rockville foundations are often used. Barges are used to transport the rocks and load them onto the foundations where the casings will eventually be anchored the ends of the casings are anchored and stabilized by ballasting this is done by adjusting the weight and balance of the casings ensuring that they remain stable and in position the process of Building a kaisen offers advantages such as shorter construction time, improved worker safety, lower environmental impact, and flexibility to fabricate and join shells in different locations before floating them to their final position. This process has revolutionized the construction of port infrastructure by providing a versatile method. and efficient to build marine structures the construction of the key wall in the new Tema port facilities at MPS Marine Port Services use the land-cast caysons method.

This construction technique involves creating and installing large concrete structures called caseins to form the key wall to begin the process. The trench is dredged into the seabed to a depth of 19 meters. This trench serves as a base for the boxes. The boxes themselves are prefabricated on land and each unit requires an

1,000 cubic meters of concrete. These huge structures weigh around 2,600 tons each. Once the boxes are finished on land, they are transported to a floating dock. To begin the transfer process, the completed shells are carefully placed near the edge of the floating dock. Inflatable airbags made of strong and durable materials are strategically placed under the boxes.

These airbags are designed to be strong enough to support the weight of the casings while also providing a low friction surface for their movement once the airbags are in position they are inflated with compressed air as they The air bags expand and inflate creating a cushion of air between themselves and the surface of the dock. This air cushion reduces friction between the shells on the dock. It is easier to roll the shells onto the floating dock using specialized equipment such as jacks. hydraulics or winches. The caseins gradually roll up over the air pockets. Smooth, controlled movement is achieved by carefully coordinating the forces applied to each kaisen.

This process ensures that the cases maintain their stability and alignment during transfer as the caseins roll over the airbags, gliding smoothly along the spring surface, the inflated airbags providing a cushioned path that minimizes any Possible impact or damage to boxes. This method is especially useful when dealing with large, heavy structures. Like the 2600 ton shells used in the construction of the key wall at MPS, at this point the floating dock is intentionally sunk, causing the shells to float and tugs maneuver the shells into their designated positions along key wall to secure them in place. They are deliberately filled with water, causing them to sink and settle to the sea floor to complete the construction.

The lockers are filled with sand and the key cover is melted on top. This last step ensures a stable and functional key wall that can accommodate various maritime activities. In the manufacturing process of the floating concrete pontoons for the urban rigger 2.0 project, mold manufacturing played a crucial role in achieving the desired shape and dimensions of The pontoon molds were constructed using a combination of rebar and steel frames to provide strength and stability during the casting process. The steel frames were constructed using strong steel bars or beams that were welded together to create the desired shape. The rebar was strategically placed within the steel frames forming a lattice-like structure.

The rebar was secured to the steel frames using wire or metal ties to ensure proper alignment and stability with the molds in place and the prepared concrete mix. The pouring process began. The concrete mixture was carefully and evenly poured into the molds, taking care to avoid the formation of air pockets or voids. This was done using a concrete pump. To facilitate a smooth and controlled flow, the bottom platform of each pontoon was built 25 centimeters thick, providing a solid foundation for the entire structure. The area covered by the lower platform measured 220 square meters per pontoon, offering ample space for various purposes.

The pontoon walls were built 20 centimeters thick to ensure structural integrity and resistance to external forces such as waves andweather conditions. On the other hand, the internal walls had a slightly thinner thickness of 15 centimeters which still provided enough strength and durability for the internal spaces to complete the pontoon structure a platform with a thickness of 20 centimeters was added on top. This platform not only served as a walking surface but also contributed to the overall stability in the pontoons' carrying capacity. The height of the pontoons varied with the lower side measuring 3.2 meters and the upper side reaching 3.62 meters.

This design allowed for a multi-level structure that accommodated different functionalities and provided a diverse living or working environment. Once the onshore manufacturing process was complete, the final pontoon was transported and set sail for Denmark, where it would be used in the Urban Rigger 2.0 project. The hull of each pontoon, excluding the deck, weighed 250 tons, while the total weight of the hull, including the deck, amounted to 330 tons. The construction of the protective belt for the new Eco District in Monaco. It began in the port of Marseille, where meticulous planning and precise execution were crucial. 18 reinforced concrete boxes, each weighing a staggering 10,000 tonnes, were manufactured to serve as a base for the offshore expansion.

The manufacturing process involved continuous casting and the boxes were poured with reinforced concrete. In large molds, these molds were placed on a specially constructed floating metal structure known as a Marco Polo. This continuous casting method allowed for efficient and continuous production of the shells. Once the concrete was poured, the shells were allowed to cure and gain strength after the curing process prepared the shells for installation, they were carefully placed and floated on the surface of the water. This floating stage allowed the shells to be maneuvered into desired locations before being lowered to sink the shells. A controlled flooding technique was used at the ends of the casings.

They were designed with specific compartments that could be filled with water. As the compartments were gradually flooded, the weight of the shells increased causing them to gradually descend into the water. The sinking process was carefully controlled to ensure that the casein sat firmly on the sea floor. This method allowed for precise positioning and alignment of the shells, ensuring a stable base for offshore extension, the weight of the shells together with their reinforced structure provided the stability needed to resist the forces exerted by the sea as the caseins They gradually sank into the water, forming a protective barrier. belt surrounding the construction area this belt served as a barrier to protect the future ecological district from the forces of the sea and at the same time provided a stable foundation for future construction activities.

The project in nbien has a length of 5000 meters and is currently being implemented through pile driving and embankment construction. This project aims to protect the coast from erosion and provide favorable conditions for the livelihoods and lives of people in the area. The construction process of the btct D300 pipeline. Piles are an essential part of the coastal protection embankment construction that contributes to the safety and sustainability of coastal infrastructure and the environment in the region.

The construction of the embankment was an important phase in the offshore extension project in Monaco. The embankment played a crucial role in providing additional stability and support for the platform and overall infrastructure. The construction process began with the transportation of materials from the quarry to the construction site. Specialized boats equipped with conveyors passed over the Kaisen belt efficiently delivering the quarry materials to the designated location. This innovative approach minimized logistics. Then, several earthmoving workshops were responsible for carefully distributing the quarry materials on the platform. Materials that normally measured zero by 50 millimeters were strategically placed layer by layer to create a strong and solid embankment.

Each layer was compacted to ensure optimal density and stability, the embankment served multiple purposes, firstly, it provided a solid foundation for subsequent construction activities, ensuring that the platform had a stable foundation, secondly, it acted as a protective barrier against the forces of the sea, protecting the ecological district from possible erosion and the impact of waves.
