Soil nailing is the process of installing reinforcement with a designed spacing of steel bars or nails in the existing ground using a top-down construction technique. The soil nail process is proceeded by installing reinforcement (bar/rod) in the drill hole in the ground, followed by grouting throughout the length. This technique is applied for stabilizing…
Micropile is a friction pile that can be both drilled and grouted and have a small diameter. The steel elements in a pile are bonded into the bearing rock or soil with cement grout’s help. These piles can be quickly installed in various kinds of ground with the use of drilling equipment. The micropile application…
Self-drilling anchors are the advanced type of fully threaded hollow steel tube rods. SDA is a fully threaded rod with an inner and outer diameter hollow steel tube. It is provided with a sacrificial drill bit at the end to facilitate the drilling process, coupler to join two SDA bars, screw nut, base plate, etc.…
Failure of rock or soil slopes takes place due to natural or artificial means. Natural events include failure due to flash flood, excessive seepage, pore pressure, seismic event, presence of weak discontinuities across the rock slope, shear zones, toe cutting of slope by meandering river leading to unstable slope due to change in slope geometry.…
Ground Anchors are the structural members that are installed deep into the rock mass with their main applicability to transfer the applied tension load deep into ground/rock mass. Sometimes, also referred to as tieback anchors. The main component of the ground tieback anchor is shown in figure 1. The anchorage is the combined system of…
