随着铁路建设事业的迅速发展,施工用房的需用数量很多,施工准备时间则要求较短。过去铁路施工用房,多用临时房屋和帐篷解决。临时房屋不但费工,修建工期长,而且由于不能移动,在迁移时要报废大批材料。此外,一般还需要大量木材,因此,在迁移较频繁的情况下,是很不经济的。帐篷虽具有灵活搬运的特点,然而造价高,使用寿命短,又需要消耗大批的棉布和羊毛。在这种情况下,为了多快好省地解决施工用房问题,活动房屋的设计,就成为目前一项急迫而重要的工作。这项工作,有不少单位已在进行,但对于我们来说,则是一项新的工作,缺乏经验,在设计和制造中遇到的问题很多。现将前一阶段设计工作做一介绍。 With the rapid development of the railway construction business, the number of construction sites needed to use a lot, and the preparation time is shorter. In the past, railway construction houses were mostly solved by temporary houses and tents. Temporary housing is not only time-consuming, but it has a long construction period. Because it cannot move, it is necessary to scrap large quantities of materials during the relocation. In addition, a large amount of wood is also generally required, and therefore, it is not economical in the case of frequent migration. Although tents have the characteristics of flexible handling, they are expensive and have a short service life. They also need to consume a large amount of cotton cloth and wool. Under such circumstances, in order to solve the problem of construction houses more quickly and efficiently, the design of mobile homes has become an urgent and important task at present. In this work, many units are already in progress, but for us, it is a new job, lack of experience, and many problems in design and manufacturing. Now we will introduce the design work of the previous stage.
