摘要
对于架棚巷道小夹角交叉点的施工,若按照常规施工方法进行施工,由于交叉点夹角较小导致开门跨度较大、抬棚棚梁过长,而影响巷道交叉点处的安全系数。结合某矿对于此类工程的施工经验,决定采用斜抬棚法进行施工。经实践证明,该方法安全可靠、施工简单,具有推广价值。
If the construction follows the normal method, the small angle intersection in the hacking shed tunnel causes long span, which affects the safety. Based on the construction experience of a mine,decides to use inclined carrying framed timber for construction. It is proved that this method is safe,reliable and simple to construct.
