Estudio comparativo técnico y económico del sistema de perforación horizontal ramming y el sistema convencional, estudio de caso

Abstract

Introduction: The article is the result of the investigation “Technical and economic comparative study of the system of horizontal perforation “ramming” and the conventional system, case study”, developed in the Universidad Católica de Colombia during the year 2016. Objective: Perform a technical and economic comparison with reference to a construction site located in the municipality of Tocancipá, which identify amounts of work, costs, construction processes, environmental impact, equipment, and construction workers, of the systems referred to in construction sites of underground networks. Methodology: It consisted of a collection of bibliographic information on the theme, acquisition and analysis of field data, and present conclusions clear and ordered fulfilling with the main purpose of the project. Results: The information of field data were obtained to make the economic comparison of direct and indirect costs, also failed to make a parallelism in the technical aspects of both technologies of intervention and finally they determined the execution times. Conclusion: Managed to find the direct and indirect costs where there is evidence that for direct costs open pit system is more economical than the excavation system, and for the indirect costs it happened otherwise. The project is a contribution of originality and interest in civil engineering since it has managed to do a complete study on a work with two techniques of intersection of pipes and an important input for developing future research has delivered. The limitation is the scarce information about the use and published research of new technologies of construction of crossings of pipelines in Colombia.
