During deep mixing, the soft soil to be treated will be crushed, and then mixed evenly with cement. The slurry can be obtained by mixing evenly. Under the action of cement solidification, a complete structure can be formed in the soft soil. Molded cement mixing piles are relatively complete and can withstand upper loads. In practical applications, cement mixing piles can improve strength and shorten construction periods, which are of great significance to engineering construction.
