In the sandy pebble stratum,the method of combining high-pressure rotary jet pile and pile anchor is worth studying.However,because pebbles with large particle size in sandy pebble stratum will hinder the formation of high-pressure rotary jet pile,the indoor test is carried out to explore the influence of additive agent on cement slurry.The research structure shows that bentonite and anti-dispersing agent have good improvement effect on the encapsulation of cement slurry and the diffusion of cement slurry.With the increase of bentonite content,the water extraction rate of cement slurry decreases gradually.
