Electrical installation design
Pit stabilization is one of the most important and specialized steps in construction projects that is performed during deep excavation to create foundations or basement floors. This operation is performed to prevent the collapse of pit walls, damage to adjacent buildings, and protect the lives of human resources and equipment. The importance of pit stabilization increases when the project is in Dense urban areas are located in proximity to sensitive buildings or old structures.
In construction projects, excavation without considering sustainability measures may lead to the collapse of walls and cause serious financial and human losses. Also, in many projects, especially in urban contexts, buildings adjacent to the excavation may experience subsidence or cracking, which can lead to legal claims and project halts.
Pit stabilization, using engineering methods, prevents these risks and enables safe and rapid project implementation.
Common pit stabilization methods
The type of method chosen is determined by the depth of the pit, soil type, proximity to buildings, and environmental conditions. Some common methods include:
Berlin Wall:
One of the most common methods in urban areas. It involves driving concrete or steel piles into a hollow wall and connecting them with a backer or brace.Soil Nailing:
In this method, rebars are hammered into the pit wall and filled with grout. They are then covered with a layer of shotcrete to reinforce the pit wall.Anchorage:
Very similar to nailing, but the rebars are longer and installed with a tension system. It is used in projects with high lateral pressure.Use of piles and micropiles:
For deep excavations or loose soils. Piles are installed vertically or obliquely to restrain forces in the ground.Strutting:
This method uses horizontal and vertical beams (struts) inside the pit to prevent soil movement. It is mostly used in deep pits in densely populated areas.
General steps for implementing pit stabilization
Geotechnical study and investigation:
Accurate knowledge of soil characteristics, groundwater levels, and possible lateral loads are among the most important prerequisites for this operation.Selecting the appropriate method:
Based on the information obtained, the design engineer selects and designs the best stability method.Implementation in stages simultaneously with excavation:
Usually, stabilization operations are carried out in stages as excavation progresses to maintain stability as the depth decreases.Continuous monitoring and control: During implementation, close monitoring by the supervising engineer and conducting soil stability tests are essential to ensure the proper functioning of the stabilization system.
