Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for compacting the earthwork density around a PHC pipe pile. Background Art

[0002] With the development of renewable energy, photovoltaic power generation projects are increasingly being deployed in various geographical environments, including desert regions. Desert regions, with their abundant sunshine resources, are ideal locations for photovoltaic power stations. However, the soil characteristics of desert environments pose challenges to the construction of photovoltaic projects. In particular, the loose nature of the sand severely affects the pullout resistance of pile foundations (such as PHC pipe piles), thereby affecting the safety and stability of the entire structure.

[0003] Currently, photovoltaic (PV) project construction in desert areas typically uses PHC piles as the foundation for supporting structures. However, due to the unique characteristics of sandy soil, traditional piling methods often fail to ensure sufficient soil density around the piles. This results in insufficient pullout resistance, making the piles prone to loosening or even failure. Existing compaction technologies, such as vibration compaction and heavy hammer tamping, have the following limitations in desert environments:

[0004] 1. Low efficiency: Traditional compaction methods often require multiple repeated operations to achieve the required density, which increases construction time and cost.

[0005] 2. Poor adaptability: Existing compaction equipment does not work well in sandy environments and is difficult to effectively improve the density of sand.

[0006] 3. Inconvenient operation: The existing equipment is large in size, not easy to carry and install, and construction is difficult in a desert environment.

[0007] Therefore, it is particularly important to develop a soil density compaction device around PHC pipe piles that is specifically suitable for desert environments. Utility Model Content
