Application of Micro Steel Pipe Pile Construction Technology in the Treatment of Large-Scale Colluvial Deposits
Anchor reinforced piles have been widely used in traditional fields such as slope treatment and foundation reinforcement.Compared with anti-skid piles or anti-skid walls,they have the characteristics of lightweight equipment,flexible pile layout,fast construction speed and strong adaptability to the site during construction,and they have been continuously promoted and applied and have achieved good engineering results in recent years.However,in some fractured bodies with complex geological conditions and the high degree of rock weathering,it is difficult to avoid hole collapse and inability to form holes in anchor pile drilling.If methods such as mud wall pro-tection and consolidation are conventionally used,it will lead to complex construction processes,longer construc-tion periods and higher construction costs,but the use of micro steel pipe pile drilling technology can effectively solve such problems.This article introduces the application of micro steel pipe pile technology to successfully solve the problems of easy collapse and inability to form holes under complex geological conditions in the treatment of large-scale colluvial deposits in the Yangfanggou Hydropower Station.
