Selected legal problems associated with road investment preparation procedures
(2010) Firek, Karol; Zgórski, Krzysztof
This article presents an analysis of the legal acts, which regulate road investment preparation procedures. The aim of this study was to identify the problems emerging upon the application of the current legal provisions, as well as to assess the effects of recent legislative amendments in this regard. The paper presents basic legal acts relating to the preparation of Road Development Projects and a general description of the procedures for obtaining the most important permissions. The assessment of the effects of latest legislative amendments has been conducted based on a comparison analysis of the current regulations with the previous ones. An example provided here was that of the construction of a grade separated motorway junction located in a traffic route over a motorway, i.e. a project prepared before 2006, and executed in 2008-2010.
Using reflectorless total stations in surveying of industrial chimney inclinations
(2010) Kocierz, Rafał; Ortyl, Łukasz
The surveying of inclinations and shape of the axis of industrial chimney structure is one of the most frequently carried out surveys in industrial plants. For this purpose, a trigonometric method is commonly applied. However, to ensure high reliability of the final product, the surveying should be carried out from more than two positions. Thanks to the development of reflectorless distancemeters (increasingly greater range as well as increasing accuracy), it is possible to develop methods which will fulfil all the accuracy requirements, while being competitive in terms of workload. In this article the author intends to present methods which could be used in measuring the inclination of the axis of industrial chimney structure. The results of conducted experimental studies were presented, showing consistency of the results which were obtained from the proposed methods with the results obtained from the classical method.
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.
Impact of mining exploitation on the road viaduct situated in the immediate vicinity of the edge of a mined wall
(2010) Kocot, Wojciech; Wodyński, Aleksander
The article presents the results of the research conducted on the behaviour of the statically undetermined steel road viaduct, located in the immediate vicinity of the edge of a mined wall. The study allowed the comparison of the predicted area deformation indices with those measured directly on the structure during the occurrence of the impacts associated with the fall of the roof, which occurred in the course of coal exploitation.
Application of IBIS microwave interferometer for measuring normal-mode vibrational frequencies of industrial chimneys
(2010) Kuras, Przemysław; Oruba, Rajmund; Kocierz, Rafał
The frequency values of normal mode of vibrations constitute one of the key elements of the technical characteristics of high industrial chimneys. The article presents the surveying of chimneys normal modes of vibrations with the use of a microwave interferometer. The system IBIS Image by Interferometric Survey is a modern measuring device, operating on the principle of microwave interferometry. This innovative surveying technique can be used for precise measurements of dislocations and strains of building structures. It allows remote measurements from the distance up to 1000 m. The high frequency of recording allows the use of this particular device for dynamic surveying of building structures. The paper presents a general technical characteristics of the interferometer. The need for conducting dynamic monitoring of industrial chimneys has been discussed. The article also presents the results of Poland's first frequency measurements of normal modes of vibrations carried out on two reinforced concrete chimneys of the height of 260 m with an interferometric radar.
