Accuracy of determining the volume of road salt storage based on surveying with reflectorless total stations
(2010) Kocierz, Rafał; Ortyl, Łukasz; Mołoń, Robert
This article presents the possibility of using reflectorless total station in the process of determining the volume of road salt. Salt of this type is stored in warehouses intended for storage of loose materials that are a part of the road infrastructure of the country. In order to perform this task, the test of three different Leica reflectorless distancemeters was conducted by carrying out surveys for a specially prepared sample of salt. The possibilities of surveying the distance for various sight line lengths and different angles of incidence of the beam on the surveyed object were examined. After the conducted test, one of the reflectorless total stations was used as an alternative tool for the hitherto surveying the inventory of road salt volume carried out using the measure to prism method. The comparative works were carried out in a warehouse located at the town of Rudno near the A-4 motorway, which was owned by the company STALEXPORT Transroute Autostrada S.A. The surveys of station poles at the salt dump were conducted on the same day, for the two instruments independently, using the polar method. The first survey was performed with the use of the ELTA R55 instrument, with the measure to prism method, and the second one with TCR407Power total station in a reflectorless mode. As a result of this test, data were obtained, which became grounds for determining the volume of the salt mass using two models reflecting the measured surface in three different computational programs. The values of the volume determined from both surveys for different models and programs were compared in order to verify the compatibility of the results with a criterion provided in the form of the values of the relative error of determining the volume, which were specified in the Survey Manual of Ministry of Heavy Industry. Additionally, a survey of the volumetric weight of road salt was carried out, which allowed the calculation of the total mass of road salt stored in the warehouse. The obtained result was compared with the inventory present in the records.

Wpływ posypywania dróg solą drogową na zasolenie gleb w wybranej dzielnicy Krakowa

Celem pracy jest określenie stopnia zasolenia gleb wzdłuż szlaków komunikacyjnych w Krakowie, po zastosowaniu soli drogowej. Badania terenowe wykonano na zieleńcach wzdłuż al. A. Mickiewicza i Z. Krasińskiego. Pobrano próbki gleby w dwóch terminach (listopad 2013 i luty 2014) i oznaczono : pH, przewodność elektrolityczną, zawartość chlorków metodą Mohra oraz zawartość węglanów metodą objętościową. Przeprowadzone badania wykazały zwiększoną zawartość zarówno chlorków jak i węglanów w glebie, po zakończeniu sezonu zimowego. Zauważono również, iż stopień zasolenia gleby w odległości 1 m od krawędzi jezdni jest znacznie większy niż w odległości 5 m. Stwierdzono, że największy wpływ na wielkość zasolenia ma ilość zużytej soli drogowej oraz natężenie ruchu drogowego w danym miejscu. W pracy zaproponowano rozwiązania technologiczne minimalizujące negatywne oddziaływanie soli drogowej na środowisko.
