摘要
通过对平煤集团天安一矿北风井井架采取碳纤维加固、外包钢及锚栓加固、灌注高效渗透性阻锈剂等措施,解决了混凝土表面碳化、强度降低、主钢筋锈蚀等问题,加固效果良好。
Some measures for strengthening derrick of north air shaft in a coal mine are introduced, including carbon fibers strengthening, wrapping steel outside, anchor bolt strengthening, and pouring high permeability rust-resistant agents. Using these strengthening measures, engineers successfully solve some difficulties, such as the carbonization of concrete, strength reduction, and rusting of main steel. The strengthening effect is good.
