Description

Technical Field

[0001] This utility model relates to the field of soft soil reinforcement technology for highways, and in particular to a crushed stone pile for soft soil reinforcement of highways. Background Technology

[0002] Crushed stone piles are an engineering structure used for reinforcing soft soil in highways. After drilling holes in the soft foundation through methods such as vibration, impact, or water jetting, crushed stone or pebbles are squeezed into the holes to form a dense pile body. Together with the soil between the piles, they enhance the bearing capacity of the foundation. They are mainly used in highway projects where there is a lack of high-quality sand sources or where environmental protection requirements are high. They are particularly effective in the southeastern coastal areas where soft soil is widely distributed.

[0003] Existing technology, with publication number CN220414201U, discloses a roadbed crushed stone pile, belonging to the field of highway construction equipment technology.

However, existing gravel piles tend to tilt during use due to the soft soil, causing them to break under horizontal forces. This reduces the effectiveness of the gravel piles in reinforcing the soft soil. Utility Model Content
