Coastal and Port Construction Solutions
Lcm Rota Maritime can perform filling at the desired point under the sea. This application is generally used for underwater ground reinforcement or pipeline filling, and breakwater construction. We carry out this process by means of the split barge in our organization.
What is sea filling, if sea filling is to be summarized, it is the filling of the sea from the shore or by different means. This filling process has more than one and several different types. So what are these methods?
The most preferred method among sea filling methods is the method of filling the sea from the shore. According to the results and statements of research conducted by people specialized in this field, the most ideal and cheapest filling method is the method of sea filling from land. If you are wondering where such filling areas exist today, one of the places filled with this method is Maltepe and another is Yenikapı. The process of sea filling; can also be summarized as trucks full of excavation material approaching the seaside and gently emptying their loads into the sea. There is an important detail that needs to be known, which is that this method is particularly suitable for use in calm seas. So, how does the excavation material discharged from the shore into the sea stay without dispersing?
Although the sea filling process is summarized as the discharge of excavation material into the sea, in fact, the sea filling process first begins with making stone reinforcement around the outer perimeter of the area planned to be filled. When the stone reinforcement is made, loads begin to be discharged into that reinforcement area, thus gradually accumulations occur in the sea and sea filling is carried out. If the fillings are being done for places like ports, that is, if an environment that will bear excessive load is being filled, in such cases, piles are driven into the filling to try to lighten the load that will come on the filling. If there are no excessively large waves in the filled area and they do not occur, these piles are driven half a meter or one meter deep into the seabed, to the boundaries of the filling areas. While the back of the driven pile is being filled, the pile is fixed to the shore via cables so that it does not undergo any structural deformation, bend, and always remains upright. These driven piles can sometimes rise up to two meters above sea level.
Another method among sea filling methods is the block quay method. Two-meter concrete cubes, each weighing between 20 and 25 tons on average, are placed one on top of the other one by one. The boundary is determined by means of these cubes. Then, concrete cubes are poured from the land and these concrete cubes sink into the water. After the concrete cubes, rocks are placed inside the filling area, thus fixing the cubes.
With sea filling, artificial chambers are created in the sea and construction work is carried out on them. In this way, new artificial areas are created by enlarging the land and coastline. Coastal fillings are among the methods frequently used by private companies to gain easy land. Additionally, if the sea filling process is not carried out in accordance with the sea structure, if filling is done with low-quality materials such as construction waste, excavation, etc., and if not working with an expert company, it will reduce the quality of the project and make the job risky. Therefore, with our expert team working within our company, we are ready to offer you the best project studies.
How is sea filling done? This question is a matter of curiosity for consumers who want to get service in this field. Of course, filling the sea is not an easy job. There are several methods of filling the sea. It is the sea filling technique most frequently used by our company and consumers. According to the preference of the majority, the filling technique from the shore is an ideal filling technique with low cost. We carry out the filling process by discharging into the sea with our fully loaded trucks. At the same time, in such fillings, to prevent the piled material from dispersing with waves, firstly, the outermost material is placed and the area is filled inside. In situations where there may be more load pressure on the fill, such as a port, tools such as piles are used, and if the piles used are not used for a high-wave area, they are driven half a meter or one meter deep from the seabed to the boundary where the fill is made. The filled pile is fixed to the shore via cables to prevent it from bending. Another filling technique is the block quay technique. In this technique, two-meter concrete cubes are placed on top of each other to determine the boundary in the sea. With this filling method, done by filling concrete cubes, they are made to sink to the bottom of the sea. Then, the filling process is completed by fixing them with rock.
Points to Consider in Sea Filling Operations
The points to consider in sea filling operations are important for the permanence of the project. It is important to correctly analyze parameters such as Project Significant wave height, wave period, dominant wave direction, and coastal morphology, etc. This process is very important for protecting coastal fillings and for the coastal protection structures built. Another important issue to be done before the sea filling project is to examine whether the desired filling and facilities comply with the Coastal Law and Regulation Provisions in the preparation of filling plans. It is necessary to take these into account for good project design. After the project is implemented, problems and changes that occur should be observed and corrections should be made when necessary. Otherwise, there is a risk of significant loss of life and property due to the disrupted coastal dynamics.
Fill port construction are projects managed according to demands. The port filling project, in simple terms, is carried out by filling the sea using necessary materials. The port is built with sea fillings provided from the land. In this project, the seabed is reinforced and filled. The areas gained by filling form the basis of port constructions. Port projects are large projects carried out meticulously. The reason why fill port projects are carried out meticulously is that they are important logistical areas and areas that will be exposed to heavy traffic. Therefore, it is very important not to allow errors in filling and construction processes.
Different sea filling methods can be applied within the scope of the port filling project. Filling the sea from the coastline is seen as the most frequently used filling method. It also stands out for being less costly compared to alternative methods. During sea filling operations, the sea is filled with materials such as marine excavation. In seas called calm seas, trucks loaded with excavation material are brought to the shore and the loaded materials are poured into the sea. The sea filling process is carried out by pouring the materials into the sea. However, before these sea filling operations are carried out, some processes are needed to keep the poured materials stable and to form fill. Filling operations begin after stone reinforcement is done. This process prevents the fills from dispersing. During port filling, the method called the block quay method can also be used. This method uses concrete cubes weighing an average of 20 tons. After the concrete cubes are placed on top of each other, they are poured into the sea from the shore. The cubes poured into the sea sink easily in the water. However, in this method as well, there is a procedure applied to keep the fills stable. Rocks are used to keep the cubes stable.
In sea filling projects, there are generally factors that determine costs. The port filling project is a project that can be affected by conditions that may give rise to different costs. In project processes, action is taken based on customer demands and conditions. Expert personnel in their fields work and technological equipment is used in port projects. All processes from the project planning phase to the completion phase are carried out meticulously. The most important element is making the plans correctly and completing the project on time.
Additional sea filling applications are procedures applied in necessary projects. In projects such as port construction on sea coasts, it is aimed to expand the areas on land by applying additional filling processes. Besides this, additional filling applications are also used to move quays to deeper waters upon requests. The purpose of these applications is to make changes in the project. In additional sea filling operations, similar to planning the project before sea filling is done, necessary planning is done by experts. Filling operations are started and the process is carried out in accordance with the plans.
The answer to the question of why additional filling is done is also a matter of curiosity. In order for the sea filling operations carried out to be called additional filling, the planned projects must have been completed. If there is a need for additional fillings after the planned sea fillings are done during the project process, refilling applications are planned. Additional filling applications are also re-planned and the project is revised. The purpose of carrying out additional sea filling operations is to expand and enlarge the filling areas in use. It is also possible to apply additional filling operations to fully provide the necessary strength for the solidity of the ground in the area where sea filling will be done. Since elements such as depth, wave sizes, and tides in field studies in areas to be filled can change over time, the area to be filled can also grow. Since the areas where the operations will be carried out generally require large-scale materials, the filling process is carried out periodically. Due to the high need for materials in the areas where sea filling will be done, the operations are carried out in this way.
The need for additional filling can arise for different reasons. For example, ports built on coasts not having sufficient space and the ever-growing logistical mobility create new requirements. The emerging requirements also indicate the need for additional filling, which is a procedure applied to expand usage areas. This application, which enables ports to grow and expand according to need, is very important for projects. The areas where additional sea filling will be done need to be under intense observation for months and examined in the smallest detail. As with all applications, additional operations are also carried out meticulously.
Seabed reinforcement and bottom filling projects are carried out by professional equipment and expert employees in the field. Within the scope of the seabed filling project, underwater ground reinforcement and necessary filling operations are carried out. In simple terms, sea filling is the filling of the sea from the coastline or different areas. In this application, it is possible to use different methods depending on different conditions. Generally, filling operations are carried out from the shore. However, alternative methods can also be preferred. In seabed filling operations, the split barge hydraulic system is used. This system is a system used in ships used for the transportation of materials such as excavation. With the split barge system, the ship splits into two sides and the load is discharged into the sea.
The seabed filling project can be carried out within the scope of different applications. Among the filling methods, the most preferred and considered ideal method is sea filling from the shore. Using this method reduces filling costs. The reason for this is that in this method, the excavation materials that need to be poured into the sea are transported by trucks and can be easily poured into the sea from the shore. Before applying sea filling methods, stone reinforcement is done to keep the fillings stable in the sea. After this process, filling materials are discharged into the area. Another method used in sea filling is called the block quay method. This method uses concrete cubes. The listed concrete cubes are poured from the land into the sea and sink in the water. Later, rocks are placed in the area where the concrete cubes are located, ensuring the cubes are fixed. The methods used in seabed filling projects vary according to customer demands and site conditions.
There are multiple factors that can affect the cost of a seabed filling project. The main goal in project processes is to produce a quality project and complete the project on time. Project processes are managed with expert personnel and technological equipment. All necessary equipment for sea filling projects and operations is used. Different methods and equipment are preferred according to the characteristics of the filling operations, and all operations are carried out meticulously. Project costs vary according to time, equipment used, and materials.
The sea filling process is a process with quite extensive details and scope. As you can guess, it is not an easy process. You can carry out the sea filling process using different methods. The sea filling technique is just one of these methods. It can also be expressed as the process generally requested from our company by users. The filling technique from the shore is generally preferred because it contains a suitable cost scale. The process steps progress with fully loaded trucks discharging from the shore into the sea. In this type of filling, the first outermost material is placed to prevent the materials discharged into the sea from dispersing with waves. In this way, the filling process continues within the created area.
If there is going to be a force that will apply a load on the fill, such as a port, tools like piles can also be preferred in such cases. If these piles used are preferred for a high-wave area, they must be half a meter or one meter deep from the seabed. It is necessary to reach this depth to carry out filling operations and reach the boundary. Additionally, to prevent situations like bending in the filled piles, they are fixed to the shore with cables.
One of the sea filling process techniques can be expressed as block quay. Thanks to this method, two-meter-long concrete cubes are placed on top of each other, drawing a boundary in the sea. Since this filling process is done by filling concrete cubes, it is aimed for them to sink towards the bottom of the sea. Afterwards, a fixing process is done by getting support from a rock and the filling is completed.
Tips in Sea Filling Operations
For the permanence of the project, there are some tips within the scope of the sea filling process. High efficiency can be obtained in operations carried out in line with these points. Correct analyses must be carried out for the area where the project will be implemented. These are;
They are divided into details like these. Additionally, it is important that this process to be carried out is done to protect coastal fillings. Another important issue is whether it complies with the rules set by the Coastal Law and Regulation Provisions. This process, which is a very comprehensive and detailed process, requires a good analysis process and work follow-up.
