Description

Technical Field

[0001] The present invention relates to the technical field of building engineering construction, specifically to the technical field of pile driving positioning, and in particular to a fixed-point positioning device used before pile driving operation. Background Art

[0002] Pile driving is a construction method used to stabilize the foundation of buildings or other structures by sinking piles deep into the ground to provide stable support. This method is often used for sites with soft or unstable soils or where increased bearing capacity is required. Pile driving effectively transfers the load generated by the building to deeper strata, thereby ensuring the building's stability and safety. During pile driving, the piles must be positioned to ensure optimal results.

[0003] Due to the rapid development of the current construction industry and the increasing demands for construction quality, pile position deviations may occur during construction. Piling operations typically require fixed-point positioning, typically performed by professional surveyors using total stations. This step is not only time-consuming and labor-intensive, but can also directly lead to a decrease in foundation bearing capacity and uneven settlement of various building components. This can affect structural stability, increase repair costs, and hinder subsequent construction. This can affect the overall building's bearing capacity and durability, hindering construction progress and increasing difficulty and cost. Summary of the Invention
