AI Technical Summary
Technical Problem
When constructing pile foundations on sloping terrain, it is difficult to control the eccentric displacement and radial slippage of the pile body. Traditional methods pose safety hazards, are costly, and have long construction cycles.
Method used
A steel sleeve is vertically positioned and embedded to form a rigid guide body. The steel sleeve is embedded below the slope surface through static pressure, vibration or spinning to provide full-circumference rigid constraint, shield asymmetric lateral pressure, and ensure the verticality of the drilling and pile-forming process.
Benefits of technology
Effective control of pile foundation verticality avoids safety hazards, simplifies construction process, shortens construction period, and reduces costs.

Abstract
The application discloses a slope terrain pile verticality control method, and belongs to the field of pile foundation construction. The method is aimed at the problems of pile position deflection and pile head slip caused by slope terrain. The method is characterized by vertically embedding a steel sleeve at a predetermined pile position and removing the soil in the sleeve, thereby converting the complex slope soil environment into a controlled vertical space environment. The method specifically comprises early-stage surveying and parameter determination, steel sleeve vertical positioning and burying, soil removal in the sleeve and cavity forming, pile foundation hole forming and pile forming construction, and post-treatment. The slope terrain pile verticality control method effectively shields the asymmetric lateral soil pressure caused by the slope height difference by using the steel sleeve, thereby eliminating the radial displacement risk of the pile head when drilling on the slope from the source. Under the premise of not damaging the overall stability of the slope, the verticality precision and construction efficiency of the slope pile are significantly improved. The method has the advantages of simple structure, low cost and strong applicability.
