Description

Technical Field

[0001] This utility model relates to the field of building square pile technology, specifically an auxiliary device for driving precast piles. Background Technology

[0002] Auxiliary devices used for precast pile driving are various specialized equipment or components that work in conjunction with the pile driving machine or directly participate in the pile driving operation during the precast pile driving process to ensure construction safety, improve pile driving efficiency, and optimize pile driving quality. Their main functions include: accurately positioning and guiding the precast pile to ensure that the pile body sinks into the ground according to the design axis and verticality, avoiding deviation or offset; clamping and fixing the pile body to prevent pile shaking or displacement during driving, ensuring pile driving stability; in addition, some devices can achieve rapid installation, disassembly, or conversion of pile driving equipment to adapt to the needs of different types of precast piles or construction processes, improving construction flexibility and reducing labor intensity.

[0003] Existing auxiliary devices for driving precast piles suffer from insufficient strength in key load-bearing components, inadequate rigidity in connection nodes, or poor stability of the supporting structure. These devices are prone to deformation, swaying, or even breakage under the impact force of pile driving or the self-weight of the pile. Furthermore, they lack compatibility with the pile body, with limited adjustment range of clamping device dimensions or uneven clamping force. This results in precast piles of different models and cross-sections not being securely fixed, leading to slippage or displacement. To address these issues, we propose an auxiliary device for driving precast piles. Utility Model Content
