Abstract
"DORMENTE ARTICULADO DE CONCRETO ARMANDO PARA GRADE DE FERROVIA". Trata-se de um dormente destinado ao uso em grade de ferrovias em substituição aos dormentes de madeira que são de baixa durabilidade e alto custo de manutenção e provocam descarrilhamentos como também aos dormentes de concreto protendido monolíticos, dormentes de ferro e dormentes de concreto armado bibloco ligado por base haste de aço todos de elevado custo e que não dissipam as vibrações na passagem da composição de forma satisfatória e ainda em caso de descarrilhamento dos dormentes de concreto ficam integralmente danificados e inutilizados. Com o uso da articulação no dormente de concreto armado reduz-se a secção e custos de fabricação, em caso de descarrilhamento substitui-se apenas um segmento, reduz-se as vibrações devolvidas à composição, contribui-se à não dispersão da cama de brita e reduz-se o risco de descarrilhamento causados por desalinhamento dos trilhos e obtém-se maior velocidade de rolamento."SLEEPING ARTICULATED CONCRETE ARMANDO FOR RAILWAY GRILL". It is a sleeper intended for use in railroad tracks to replace wooden sleepers, which are of low durability and high maintenance cost and cause derailments as well as monolithic prestressed concrete sleepers, iron sleepers and reinforced concrete sleepers. connected by steel rod base all of high cost and that do not dissipate the vibrations in the passage of the composition in a satisfactory way and even in case of derailment of the concrete sleepers they are completely damaged and unusable. With the use of the joint in the reinforced concrete sleeper, the section and manufacturing costs are reduced, in the event of derailment, only one segment is replaced, the vibrations returned to the composition are reduced, the gravel bed is not dispersed. and the risk of derailments caused by misalignment of the tracks is reduced and greater rolling speed is achieved.
