Description

technical field

[0001] The invention belongs to pile forming in building foundation construction, in particular to a novel cement-soil pile and a pile forming method thereof. It is used for forming piles such as composite foundation piles, slope protection piles, and water-stop curtain piles. Especially in peat soil, silt, quicksand and sandy pebble formations. Background technique

[0002] Cement-soil mixing piles are widely used in fields such as foundation treatment, foundation pit support, and water-stop curtain piles because of their simple construction and low cost. are greatly restricted. For example, peat soil in a site in Kunming area is black, black gray and brown, saturated, soft to fluid plastic state, and highly compressible. The specific gravity is close to 1.0, the pores are large and loose, the void ratio e=3.01-8.04, the average value is 5.63, the average water content is 267%, and the average organic matter content is 45.4%. It is a strong peaty soil wit...
