Szukana fraza: [Abstrakt = "Military foldable bridges, apart from usual military application, can be used in the peacetime to erect temporary bridges in crisis situations \(e.g. flood or failures and crashes of bridges\) and in a case of absolute necessity \(repairs and reconstruction of road bridges\). The foldable constructions are characterized by the limited service life compared with fixed structures, their advantage lies in the improvement of the traffic during the development of road infrastructure. In this situation the erection of a temporary detour or a separated intersection made of foldable structures improving the flow of the traffic and acting as a temporary measure allowing for the materials to be collected for fixed constructions. They meet normative requirements defined by economical procedures. The constructions do not require additional reinforcement as temporary bridges. The paper describes some selected applications of collapsible constructions to erect temporary bridges in Wrocław. The presented structures \(DMS\-65, MS\-54, MS 22\-80, KD\-66C\) allow for quick and easy assembly of bridge spans and supports. In the conclusion are given the development perspectives of said constructions."]
