一、概述在铁路施工组织设计中,都不喜欢冬季施工,特别是桥基的冬季施工。因为工作效率低,施工进度慢,增加防寒费用多,气温越低,冷的时间越长,情况就越不利。可是,当气温降到一定严寒程度,此时冬季施工反而会向有利方向转化。本文所介绍的就是其中的一个例子。它不但解决了施工组织设计中有时要在冬季中断施工的缺点,争取了施工时间,平衡了劳动力,加快了施工进度;而且还节约在夏季施工时所需的大量防水(围堰工程)、抽水费用。它是一个切实可行的好方法,在我国东北、内蒙等严寒地区铁路桥基施工中,已取得了不少成功的经验。
First, an overview In the railway construction organization design, do not like the winter construction, especially the construction of the bridge base in winter. Because of low efficiency, slow construction progress, increased cold-proof costs, the lower the temperature, the longer the cold, the more adverse conditions. However, when the temperature dropped to a certain degree of coldness, the construction in winter would instead turn to a favorable direction. This article describes one of these examples. It not only solves the shortcomings of construction organization design sometimes interrupted in winter construction, strives for the construction time, balances the labor force and accelerates the construction progress; but also saves a lot of waterproofing (cofferdam construction) required in summer construction, pumping cost. It is a feasible and feasible method. In the construction of the railway bridge foundation in the cold regions of northeast China and Inner Mongolia, China has obtained a lot of successful experiences.
