A Review Paper on Lithely Arch Bridge

Abstract

Abstract: In this we are studying modern technology of arch bridges i.e “Lithely Arch technology”. In this technology the blocks are precasted, blocks are jointed with screed concrete and lifted to a location by transporting them on site and again lifted to form arch bridge and then working towards the finishing. It also includes the study of reading the drawing, Bearing capacity, prepared all over detailed estimate and stability checks. Various IRC codes, IS codes is studied. The masonry arch is one of the oldest structural elements. Brick masonry arches have been used for hundreds of years. This technical note is an introduction to brick masonry arches. Many of the different types of brick masonry arches are discussed and a glossary of arch terms is provided. Material selection, proper construction methods, detailing and arch construction recommendations are discussed to ensure proper structural support, durability and weather resistance of the brick masonry arch. Lithely arch method is innovative, modern, economic and fastest method of construction of arch bridges. This method is invented in Maharashtra, India. Bridges constructed using this method are purely compressive in nature. This method utilizes precast units for construction of arch bridges. This method can be utilized for rehabilitation of old arch bridges in India very economically and with less time. The lithely arch is India's only Precast, Unreinforced Bridge solution and is developed on the lines of the conventional stonemason built arch bridges. Arch bridges are the most reliable and time tested solution for medium span (5m to 20m) bridges. These bridges have been standing strong for centuries and while they were initially designed for 8-10 tons of load are carrying modern vehicular load without any distress.
