Study proposes that Public Works review the construction system of road drainages

SANTO DOMINGO. A group of graduates of Instituto Tecnológico de Santo Domingo (INTEC) proposed that the Ministry of Public Works and Communications (MOPC) implement a new model for the construction of the drainage system by encachado on the roads of the country, to make them safer and cost efficient.

The civil engineers Jordan Pantaleón, Paola Pérez, Rogelio Cordero, Aurelio Torres, Bryan Arturo García, Heliana Castillo, Joemi Feliz and Gioribel Rivas, determined that the calculation of the friction applied to build the drainage systems of the country's highways It corresponds to the materials that are used.

According to the MOPC manual, a formula that has a friction factor (Manning factor) of 0.001 for concrete and another of 0.030 for rock is used to calculate the measurements of gutters in the country. However, when drainage is not built by pitching with these two materials, it has become common practice to use one of the ends, to avoid intermediate calculations.

Professor Martín Meléndez, technical advisor of the research and specialist in Disaster Management, states that using the smallest friction parameter causes ditches to be constructed with measures that increase the possibility of flooding of the roads, given their inadequate size. Also, alert that opting for the highest friction factor is also incorrect, as construction costs skyrocket unnecessarily.

The results of the research of the graduates of the INTEC pose the need that for the construction of road drainages by encachado the Manual of Public Works include a parameter of 0.24, intermediate between the concrete and the rock, so that it responds with greater accuracy to the requirements of the roads. This value has a level of reliability of 95% verified by more than 100 laboratory samples and drainage construction models.

The study was published in the journal Science and Society, a quarterly body of scientific dissemination of INTEC, which has been published for 34 years in the country.

"The great contribution of this study is an average value for the design of gutters, which would reduce the likelihood of flooding and unnecessary expenses in the construction of drainage by encachado," said Meléndez, who advised the research along with INTEC professor Tulio Rodríguez

The young people started the process of intellectual registration of their proposal in the National Office of Industrial Property (ONAPI) to then complete the formal application process to include your model in the Public Works manual.
