【摘要】 针对丁集矿井的特殊水文地质条件,为防止井壁在冻结壁融沉和地层疏水沉降时发生破裂,在井壁设计时采用竖向可缩性结构,并提出了一种新型可缩性冻结井壁接头。模型试验表明:在竖向附加力作用下,研制的可缩性接头具有良好的压缩变形特性,抗侧压能力大,防水性能好,可应用于工程实际。更多还原

【Abstract】 Aiming at the special hydrogeological condition of Dingji mine, vertical reducible structure is adopted when the wall of a well is designed to prevent it from break while freezing wall is thawed and the stratum is settled ,and a new type reducible joint of freezing wall of a well is hold up. Model test indicate:at effect of vertical additive force, reducible joint has good characteristic of compressing distortion and resists greater side pressure and has good capability of waterproof, it can be applied to practice project.更多还原
