The paper "Bridge Support Construction Process" is a worthy example of a report on engineering and construction. The construction of bridges has become an important part of today’ s infrastructure. The use of the bridge for roads is however advisable in any case the two locations cannot be linked together by road without the use of a bridge. In most cases, the topology of the land is the main determinant of the bridges that need to be constructed. This considers the stability of the terrain, the length of the bridge that needs to be constructed and the Loughor Bridge Crossing will be constructed to help connect Cardigan with Swansea.
The two locations are divided geographically by the Loughor River. To increase the activities between these two cities, the bridge will have to be installed in the location. The first issue was to determine the best type of bridge to construct for the area. There are currently four types of common bridges known and used in the world today. The beam bridges are the most common and cheapest bridges to construct. However, these types of bridges are limited to the type of terrain that they can be used.
The other types of bridges are the cable stein bridges or the suspension bridges, the arch brides and the cantilever bridges. Since the time and finances for the organization are limited, the beam bridge will be constructed. Before the actual construction begins, all the necessary conditions will have to be considered to ensure that the conditions necessary for the proper and easy construction of the bridge are provided. It has been identified that there are four pillars that will be constructed below the beam bridge to provide the bridge with the necessary support and foundation to enhance the quality of the structure. The construction plan to be used for the site will be as follows; Site layout Construction of the cofferdam Dewatering of the construction area for the bridge construction to begin Excavation of the soft soil Pile constructions Construction of the end piles and supporting columns Flooding of the cofferdam Removing the sheet piles and bracing Adopted from: Before the start of the building process, a cofferdam will have to be constructed to provide short term drainages for the river to help build the foundations for the bridge.
The cofferdams are the temporary dams that are constructed near the construction areas in order to help keep out the water and soil in order to allow for dewatering and construction of permanent structures to be made within a limited time in the dried area. The cofferdam helps to reduce loads such as hydrostatic forces of water and the dynamic forces that are experienced as a result of the wind currents and waves. In our case, the depth of the water is shallow and the soft soil and mad in the areas go to a depth of about three to four meters.
For our case, therefore, the braced cofferdam will be the best suited for the site. The braced dam worked best for the shallow waters of not more than 35 ft deep. The braced cofferdam is constructed from a single wall of sheet piling. The sheet piling is driven into the ground where a box-like structure will be formed around the excavation site. The successful construction of the cofferdam will be reliant on three major factors.
There are successful site investigation sampling and relevant testing to being a good image of the task that is to be completed, a good design for the different stages of construction for the project and finally, the setting out of piles and their secure and complete installation in the dam.
