[0002] Among the methods of foundation pit support, soil nails and composite soil nails are widely used and the cost is relatively low. However, if soil nails or composite soil nails cannot be used due to soil quality reasons and the large depth of the foundation pit, a deep mixing pile support structure is generally used. The current mixing pile support structure is a concrete pile arranged on the edge of the foundation pit. This can prevent the collapse of the soil on the edge of the pit when digging the pit, and prevent water from seeping into the pit from the pit wall. After searching the utility model with application number CN202220433198.2, a deep mixing pile support structure for cement mixing piles is disclosed.
