Technical Field
[0001] This utility model relates to the field of mixing pile construction technology, and in particular to a construction tool for mixing pile construction in pebble layer. Background Technology
[0002] Cement mixing piles are a type of soil treatment system that uses cement as the main curing agent. A mixing pile machine injects cement into the soil and mixes it thoroughly, causing a series of physicochemical reactions between the cement and the soil to improve the foundation strength. Cement mixing piles are classified into single-axis, double-axis, and triple-axis mixing piles based on their main construction methods.
[0003] Mixed soil mixing piles are difficult to construct when encountering thick and large gravel layers because the piles cannot penetrate the strata, resulting in low construction efficiency and compromised pile strength. To address this, casing is typically used in conjunction with a drilling rig. However, existing casing structures are simple and difficult to operate during construction, reducing efficiency. Furthermore, casing positioning during installation is challenging, further decreasing efficiency.
[0004] Therefore, the existing casing used for mixing pile construction has a technical problem of low construction efficiency due to unreasonable structure. Summary of the Invention
