It is necessary to set up slagging well to facilitate slagging and improve construction efficiency during the construction of tunnel shaft inverse well method. Due to the geological condition of the shaft and human factors, the slag chute is easily blocked and the construction period is affected. The conventional dredging method has some problems such as low efficiency, complicated process and long time limit. In this paper, based on Yunnan province Taihe Sumie to Lincang highway tunnel shaft engineering, put forward a way to use two strands in a certain distance between wire rope clamp, two of the same height of the steel wire rope clip through the switch assembly structure of the hinge connection, can be efficient and convenient to dredge the well construction shaft sneak slag well jam problem, as a reference for other similar projects.
