Description
Technical Field
[0001] The utility model relates to the technical field of vibro-stone piles, in particular to a reinforcing device for vibro-stone piles. Background Art
[0002] Vibro-stone piles are a special type of pile foundation engineering technology, which is usually used in foundation improvement and infrastructure construction. The main purpose of this technology is to improve the engineering properties of soil and enhance the bearing capacity of the foundation in order to support buildings or other infrastructure; the main function of vibro-stone piles is to increase the bearing capacity of the foundation, stabilize the foundation, and reduce the risk of foundation subsidence; this technology is usually used in buildings, bridges, docks, roads and other infrastructure projects, especially in areas with poor soil conditions.
[0003] Vibro-compacted stone piles usually involve the following main steps: Drilling: First, drilling is carried out in the area where foundation improvement is required to prepare the hole to receive the stone pile; Delivering the stone: Next, the stone is delivered to the hole; this stone is usually gravel or similar material; Vibro-compacting: Using special vibro-compacting equipment, the stone pile is vibrated layer by layer to sink the stone into the hole. This process will make the stone densely arranged and improve the engineering properties of the surrounding soil; Compacting: Once the stone pile is installed, compaction work can be carried out to ensure a tight connection between the pile and the soil.
[0004] However, when water seeps into the holes and the foundation is subjected to very high pressure, the connectivity between the gravel in the holes will be greatly reduced, and they will slip against each other, causing the foundation to settle and its bearing capacity to be greatly reduced. How to carry out high-quality reinforcement of vibratory crushed stone piles has become an urgent problem to be solved in engineering. Utility Model Content
