Abstract

Bored pile construction equipment has a variety of types, features, methods of cutting soil, taking soil chips and especially many manufacturers provide construction equipment. However, the equipment for construction of bored piles with small diameter serves the solution of reinforcing foundations in crowded constructions in large urban areas with small area and technical infrastructure of poor access to the work. Very few manufacturers care about. The speed of urbanization is large, the need to build new and replace old and degraded works in big cities is increasing, the selection of a suitable construction technology solution to ensure technical an, artistic requirements and meeting economic targets is an overall problem. The article introduces construction equipment "small diameter bored piles" for the construction of bearing piles, earth retaining wall, suitable for narrow construction site conditions. Including the process of selecting basic equipment, working equipment, drilling rods, concrete pouring pipes and supporting equipment system for construction work.
