As an important part of modern transportation infrastructure,the construction quality of expressway directly affects the safety,durability and service life of the road.As an efficient foundation treatment method,wet spraying pile technology is widely used in highway foundation reinforcement projects because of its advantages such as fast construction speed,wide application range and good pile quality.Based on this,this paper will start from the basic theory of wet spraying pile construction,and systematically analyze its construction technology and technical points,including slurry ratio and quality control,optimization of drilling and remixing technology,construction quality control and pile quality inspection.It is hoped that it can provide valuable reference for engineering and technical personnel and promote the further application and development of wet spraying pile technology in highway construction.
