The construction of soil nailing / Muhammad Eizzam Mohd Zin

Soil nailing is a remedial construction measure to treat unstable natural soil slopes or as a construction technique that allows the safe over-steepening of new or existing soil slopes. This construction is to avoid the soil slopes from collapse. However, currently there is limited research conducted on proper construction of soil nailing. Therefore, this report will discuss about soil nailing and grid beam construction at repairing slope at SMK Desa Petaling, Jalan 3/125, Taman Desa Petaling, 57100 Kuala Lumpur, Wilayah Persekutuan Kuala Lumpur. The objective of this report is to determine the construction of soil nailing and the method how to carry out. It will focus on the whole process starts from site clearance until construct nail head. In addition, the soil nailing construction has approximately 7 steps to follow starting from site clearance, setting out process, drilling, inserting steel bar, fill grout and pull-out test. It is also to investigate about the machinery and equipment that be used in soil nailing such as portable drilling rig, air compressor, control panel, power pack, grout mixer and others. This report is also to discuss about the problem that has been faced during the project such as the slope surface was collapse and the soil containing a hard rock. This report also to figure out the best solution to handle the problem and how to avoid that obstacle from repeat again. As conclusion, soil nailing construction is very important to prevent the landslide especially to an area who has high risk such as residential area at the hillside and so on. Thus, by knowing the proper soil nailing methods it can help the contractors in other to strengthen their knowledge in soil nailing construction for the future.
