Soil stapling is an economical technique to achieve stability in slopes and to build retaining walls from top to bottom Bottom and side support from the surrounding area The excavation of the site begins with a depth of between (1.5 – 2 mm) The first row of soil stapling, 0.75 m deep, is designed by design. Then the sprayed stage and those fans It is located in the middle of the thickness of the dance layer and put a grid parallel to the planned wall After that, short plastic pipes with a diameter of 20 cm are installed in the places where the soil is stapled.
After finishing the shot crete layer, a hole for reinforcement is made with a diameter and an inclination according to the design. After that, the reinforcing skewer is placed inside the hole, taking into account the installation of metal or plastic parts (lanterns). The entire length of the iron skewer and at 1.5 meter intervals to keep the skewer central inside the hole. After that, drilling starts after placing the reinforcing bars for the entire length of the hole from the bottom to the top. After completing the work of soil nails, steel plates of specific dimensions that were designed are installed And fixing nuts on the head of each skewer in order to increase the cohesion and contact between the reinforcement of the shotcrete And reinforcing bars for soil stapling.
