勘探工程中送水管路防寒是冬季施工中保证生产,防止发生事故的重要问题之一。特别是东北地区气候寒冷,过去由于缺乏妥善的防寒方法,经常发生水管冻结事故,不但损失管材,造成浪费,而且影响了勘探工作。去年冬季我队曾采取了以绝缘材料(稻草、纸带蔴刀等)包紮铁管,水池烧热水,加大水箱容积,減少送水次数,敷设备用管路等方法,来防止水管冻结。但是这些方法不仅拆卸搬移麻烦,成本昂贵,而且也不能完全杜绝冻结事故发生。特别是在山势陡峻,岩石坚硬的地区,更不宜采用埋入地下的方法。对于某些浅鑽孔来说,因经常搬迁,采用固定性防寒设备是不经济的。为了克服这些毛病,我队去年曾在 The prevention of cold in the water supply pipeline in exploration projects is one of the important issues in ensuring production in winter construction and preventing accidents. In particular, the northeastern region has a cold climate. In the past, due to the lack of proper methods to prevent cold, water pipe freezing accidents frequently occurred. This not only caused loss of pipes and caused waste, but also affected exploration work. In the winter of last year, our team had adopted methods such as insulating materials (straw, paper tapes, etc.) to wrap iron pipes, pools to burn hot water, increase the volume of water tanks, reduce the number of water supply, apply pipelines for equipment, etc. to prevent freezing of pipes. However, these methods are not only dismantled and removed, but also costly, and they cannot completely prevent freezing accidents. Especially in areas where the mountains are steep and the rock is hard, it is even more inappropriate to use underground methods. For some shallow boreholes, the use of fixed cold-proof equipment is not economical due to frequent relocation. In order to overcome these problems, my team
