Resumen
RESUMEN: El objetivo de la memoria es dar solución del saneamiento al proyecto del enlace vial
rotonda Bonilla que forma parte del estudio licitado por el Ministerio de Obras Publicas,
desarrollado por la empresa Consultores de Ingeniería Ltda. denominado
"Mejoramiento y Ampliación Rotonda General Bonilla", en la VIII Región. Este enlace
corresponde al acceso norte a Concepción donde confluyen importantes autopistas de
alto transito.
El estudio desarrollado como parte de la presente memoria de titulo da la solución del
saneamiento de la rotonda y áreas vecinas, incluyendo calles que convergen a ella y
también optimizar el canal Pocitas existente. Para determinar esta solución, el estudio
se basa en el planteamiento que da para el sector el Plan Maestro de Evacuación de
Aguas Lluvias de Concepción y en criterios de diseño del Manual de Carreteras de la
Dirección de Vialidad del Ministerio de Obras Publicas, ya que el diseño de las obras
forma parte del estudio vial mencionado. Estas obras están aprobadas por la Dirección
de Obras Hidráulicas del Ministerio de Obras Publicas.
Con los antecedentes mencionados, se plantean y evalúan las obras necesarias para la
nueva red de saneamiento que incluye la verificación y proyección de obras tales como
colectores de aguas lluvias, sumideros, canales, fosos, etc. Para ésto se realiza
preliminarmente el estudio hidrológico para el sector el que se compara con lo que
plantea el Plan Maestro, obteniéndose las precipitaciones de diseño.
El principal problema que se encuentra en el sector, es el punto de evacuación que
plantea el Plan Maestro a través del canal Pocitas que descarga en el río Andalién ya
que la diferencia de cota que tiene el sector en estudio con respecto a los puntos de
descarga es baja, esto impide mejorar las pendientes de los colectores, para así lograr
descargar de manera normal, obligando a diseños muy ajustados.
Se concluye que el sistema que se proyecta permite la descarga de aguas lluvias al río
Andalién para crecidas de hasta 10 años de periodo de retorno
El presupuesto estimativo que se confecciono, en base a obras tipo y precios unitarios
entregados por Consultores de Ingeniería Ltda. en el año 2007, es de $858.382.185
netos.
ABSTRACT: The purpose of memory is to solve the drainage project Bonilla roundabout highway link is part of the study tendered by the Ministry of Public Works, developed by the Engineering Consultants Ud. company called "Improvement and Expansion General Bonilla Rotonda" in Region VIII. This link is for the northern access to Concepción, where major highways converge high traffic. The study developed as part of the title referring to them memory gives the solution of the reorganization of the roundabout and surrounding areas, including streets that converge to it and also optimize existing Pocitas channel. To determine this solution, the study is based on the approach to the sector given the Master Plan for Stormwater Disposal of Conception and design criteria of the Manual for Roads Department of Roads, Ministry of Public Works, as the design works part of the study mentioned road. These works are approved by the Department of Water Resources, Ministry of Public Works. With the above background, we propose and evaluate the work required for the new sewerage system, including verification and screening of works such as storm'water collectors, drains, canals, ditches, etc.. For this preliminary study is performed hydrologic industry that compares to what poses the Master Plan, obtaining the design rainfall. The main problem encountered in the sector, is the evacuation point raised by the Master Plan through Pocitas channel which discharges into the river Andalién since the difference in elevation that the sector under study with respect to the discharge points is low, this prevents improve the slopes of the collector, thereby bringing download normally, forcing tight designs. We conclude that the system is projected to allow storm water discharge to the river to flood Andalién 10 years return period The budget estimate is formed, based on work type and unit prices provided by Engineering Consultants Ud in the year 2007 is $ 858,382,185 net.
