采用冻结法施工的处理井,因冻胀力、低温等原因会造成已有混凝土起皮、开裂、掉块等破损,若不采取合理的保护措施,会出现严重的质量问题和经难以估量济损失,比如说内蒙古的塔原高勒主、副、风井。核桃峪矿风井井筒开创性的采用了加热孔循环措施来保护已有井壁,并取来了良好的效果。 Due to frost heaving force, low temperature and other reasons, existing treatment wells with freezing method will cause peeling, cracking and falling off of the existing concrete. Without proper protective measures, serious quality problems and difficult to estimate economic conditions will occur Losses, such as the tower of Inner Mongolia, the main high, vice, wind shaft. Walnut Valley mine shaft mine pioneered the use of heating hole circulation measures to protect the existing shaft wall and take good results.
