Reinforcement of Tunnels Facades And Entrances

Reinforcement of Tunnels Facades And Entrances

The need is urgent and necessary when using shotcrete or shotcrete in the works of constructing and strengthening the sides of trenches, tunnels, large swimming pools, and small pools, as well as works to support weak soil when digging trenches, tunnels, and large roads, because shotcrete may be used in such circumstances to strengthen it either in terms of its nature You may use a dry or wet projectile.

Where the mountain facades and entrances to the tunnels appear after cutting the rock in an unsafe shape, which is a result of the remnants of blasting and cutting with equipment, and because the mountain is formed from various rock layers, sometimes it is heterogeneous (Hard Rock & Witherrd Rock), especially when cutting to high altitudes, there may be rocky blocks that suggest the eye With the seriousness of its existence, and to overcome this feeling and also to give cohesion between the rocks and to feel reassured and comfortable, concrete sprinkles are used on the front of the mountain.

It is about coating the facades of the rock cuts with a galvanized mesh "against rust", an iron mesh . It is spread over the entire surface of the mountain façades and fixed with iron rods, taking care to create a space between the grille and the mountain, then this façade is sprayed (with a throwing system) with a layer of high-quality dry concrete . Thus, the general shape of this facade is transformed from a rocky, mountainous, unsafe and heterogeneous facade into a homogeneous panel that gives confidence in safety and prevents the fall of rocks and dust of small size and resists erosion factors for decades.
