我国地域辽阔,纬度跨度较大,尤其是有些地区都处于高寒地区,这就对我国的基础设施建设造成很大的困难。道桥建设是基础建设中非常重要的部分,它的施工受环境的影响较大。尤其在我国北方,冬季严寒漫长,非常不利于施工。在冬季施工因温度低对混凝土浇筑的影响是最大的,不但耽误了施工进度还造成了巨大的经济损失。近年来我国正在治理研究冬季混凝土的施工技术,取得很大进步。针对这一技术进行论述。
Our country has a vast territory and a large latitude span. In particular, some areas are in the alpine region, which has caused great difficulties for China’s infrastructure construction. The construction of the bridge is a very important part of the infrastructure and its construction is greatly affected by the environment. Especially in the northern part of our country, the winter is very long and cold, which is not conducive to construction. Due to the low temperature in winter construction of concrete pouring is the greatest impact, not only delayed the progress of construction has also caused huge economic losses. In recent years, our country is managing the construction technology of concrete in winter and has made great progress. Discuss this technology.
