摘　　要：预制管桩因具有高强度、质量稳定和成本低等优势被广泛应用于各类建筑,其中高质量和高效率的焊接接桩对于充分发挥预制管桩的承载力具有重要影响。由于目前人工焊接接桩存在质量不稳定、劳动强度大以及效率不足等问题,因此研发了预应力管桩焊接机器人。本文在已有的研究基础上,为解决现有焊接机器人移动困难、复杂场地适用性不足等问题,研发了履带式管桩焊接机器人,并在具有复杂场地条件的软土地层管桩工程项目中进行了应用。为验证焊接接桩质量,开展了焊缝检测和桩基承载力测试。结果表明:履带版焊接机器人在复杂场地条件中移动灵活,有效节省了移动时间和施工成本,显著提升了焊接效率。焊缝检测、施工管桩静载和接头传力测试结果表明,采用机器人焊接接头传力稳定,焊接质量高,可以满足高质量管桩焊接施工要求。Prefabricated piles are widely used in various buildings due to their advantages,including high strength,stable quality,and low cost.The high quality and efficiency of welded piles significantly impact the full bearing capacity of prefabricated piles.To address issues such as unstable quality,high labor intensity,and insufficient efficiency associated with manual welding,a prestressed pipe pile welding robot has been developed.Building upon existing research,this paper introduces a crawler-type pipe pile welding robot to enhance the current robot's mobility and applicability in complex sites.The developed robot is applied in the pipe pile project for soft ground with complex site conditions.To validate the quality of the welded jointed piles,both weld testing and pile bearing capacity testing were conducted.The results show that,The crawler version of the welding robot moves flexibly in complex site conditions,effectively saving the moving time and construction cost,and significantly improving the welding efficiency.The results of weld inspection,static load and joint force transmission test show that the robot welding joint force transmission is stable and the welding quality is high,which can meet the requirements of high-quality pipe pile welding construction.
