Casings wall，a celebrated term of civil engineering，refers to the use of pre-constructed casing walls made of reinforced concrete to build a bridge foundation or socket foundation. It is mainly used in the construction of bridge foundation structure and other deep foundation engineering, and has the advantages of convenient construction, high construction quality and rapid completion.

The reinforced concrete casing wall is a reinforced concrete structure with a certain thickness. Generally, the external pressure will be relatively large, and the internal pressure should be relatively small, so it can be regarded as a box structure with internal thin wall thickness. It is mainly used in the construction of the socket foundation of bridge foundation structure and other deep foundation engineering.

The casing wall is composed of several parts: reinforced concrete casing, reinforced steel, bolt and wedge. The reinforced concrete casing is generally rectangular in shape, and the reinforced steel is embedded in the wall body of the casing. After the reinforced steel is fixed by the wedge bolt, it can form a robust reinforced concrete structure, which is resistant to external pressure and stable in structure.

The method of construction of reinforced concrete casing wall is divided into two steps: firstly, the casing wall is pre-constructed in the factory and then transported to the bridge site; secondly, the casing wall is put into the foundation excavation and the bolts and wedges are used to fix the reinforced steel. After that, the concrete cement is poured into the casing wall and the reinforced concrete structure can be formed.

The use of casing wall can bring about several advantages. First, it can shorten the construction period, make full use of prefabricated components and improve the construction quality and quantity of the project. Second, it can also better protect the environment, reduce the disturbance to the area, and maintain the integrity of the original ecological environment. Finally, it can also reduce the cost of construction, the cost of labor and materials, and greatly save the construction costs.

In conclusion, the use of reinforced concrete casing wall technology has obvious advantages in civil engineering projects. It can not only save construction costs, but also reduce the waste of materials and improve construction efficiency. It is a very hot technology in the field of engineering construction.
