What is soil nailing of the wall? Stabilization of the wall
rose roofing: If you don’t know what nailing is, it should be noted that nailing is one of the methods of protecting trench and pit walls, which is very widely used in urban spaces.
Nailing was one of the creative methods of Australian engineers that has been used to improve the soil and strengthen the building. This method was first used to stabilize the tunnel, but later it was used in the construction industry and stabilizing trenches.
nailing
In general, the method of using nailing is that first the walls are adjusted, and then a network of steel meshes is driven into them with 50 cm long nails, and the surface is covered with cement with a diameter of 10 15 cm will be covered, the next step is the borehole and the placement of rebars. After this method, cement slurry will be injected into the place and after this step, the head nails will be closed. In fact, it is one of the best methods to deal with earthquakes and It is possible to strengthen load-bearing walls by implementing the nailing method.
In this case, the thrust of the soil caused by earthquakes and landslides is applied to the nails through the mass of soil, the thrust of the soil is restrained through the nailing system and is not transferred to the surface of the building and the walls. Later, it was used by French and German engineers to stabilize tunnels and stairwells. Nailing is considered a guard structure and increases the strength of the building’s skeleton.
What is nailing?
Nailing is one of the most popular methods of wall protection and there is a high speed in its implementation because several parts of its work can be done simultaneously. Stabilization of the wall with the nailing method can be implemented in a wide range of soil types, and it is possible to implement it in a vertical pit as well.
In excavations where the depth of the pit is very high and it is not possible to use inclined or stepped excavation, the method of nailing or nailing the soil is used to do this. This method has many applications in stabilizing slopes and gables and increasing their load-carrying capacity and creating restrictions on deformation, especially in urban projects.
In order to be able to use this method for the stability of the structure, the local soil must be able to maintain stability at least up to a depth of 1.5 meters. After the earth removal of the first step is done, the first row of nails is executed and then a concrete surface is drawn on the work. After that, the same process should continue until you reach the last level of digging.
It is very common and appropriate to use this method to stabilize structures that are built underground, such as subway stations.
Strengths and weaknesses of wall stabilization by nailing method
The nailing method is only one of the wall and pit stabilization methods, which has its advantages and disadvantages.

The strengths of the nailing method
This method can be used for places where spaces are very close to each other and many buildings have been built near the project site. For this reason, it is a very suitable method for urban spaces.
Uniaxial test
The nailing method is a very environmentally friendly method, and for this reason, it solves the concerns of many people.
This stabilization method has a lot of flexibility in implementation. The meaning of the implementation is the possibility of adapting the structure to the unevenness and different conditions of the land.
These structures are very good options to be implemented near the structures that are sensitive and it is possible to sit in them.
Nailing is an economical method. The materials and tools used in the nailing method make the final price of the structure much lower than other types of stabilization methods. It can be used for structures that need less than 18 months to be built, as well as structures that need a longer time because nailing can be applied in temporary and permanent ways. In situations where smaller tools and devices must be used due to space limitations, it is recommended to use the nailing method.

Weaknesses of nailing method
This method can be done with the help of the surrounding buildings, that is why the owners of the surrounding buildings must be satisfied to use this method. The tools used for nailing produce a lot of noise and may cause annoyance to the local residents.
Stabilization of pit and wall by nailing method
Walls that are nailed can be implemented in two ways, temporary or permanent.
Temporary nailing: Temporary nailing has a lifespan of less than eighteen months. Sometimes it is seen that a trench or pit is temporarily nailed, but it took more than eighteen months to build.
In this case, permanent excavation systems should be used for stabilization. For this purpose, pits are dug in the ground in which the pipes or rebars are placed and the empty space is filled with cement slurry.
Permanent nailing: When a structure is permanently nailed, their lifespan will last more than 18 months.
