Abstract
In the construction of high chute,the common method,hanging tank method and other construction methods are used less and less,and the method of using patio drilling rig to construct chute is used more and more.At present,it has been basically popularized and used[1-3].For the chute with a height of more than 50 m,this paper puts forward a new method of chute expansion through analysis and research,which solves the disadvantages of low efficiency and long construction period of traditional methods.Through many times of field construction,it is proved that the method is safe and efficient to complete the expansion of high chute.关键词
