摘要
为了解决传统非脱钩强夯机的机身稳定性差、施工效率低、操作灵活性差和施工质量保障难等难题,结合强夯施工特点,采用了创新性的机械液力传动系统、施工臂架平台动态稳定技术、夯击深度自动检测技术、卷扬多级安全制动技术、控制系统等多项技术,研发了新型机液一体式非脱钩强夯机。结果表明:新型非脱钩强夯机实现了起锤、放锤及夯锤空中起停的灵活操作,具有大扭矩、高效率、高稳定性、高安全性的优点。工程实际应用表明,在相同的工况条件下,采用新技术的非脱钩强夯机的施工效率是脱钩强夯机的2.5~3.0倍,与强夯智能施工管理系统结合后,不需现场挂钩和人工测量,进一步提升了施工效率,同时解决了施工安全问题。该研究可为非脱钩强夯施工工法的推广、非脱钩强夯设备的发展方向提供参考。
Due to the challenges of inadequate stability,low construction efficiency,limited operational flexibility,and difficulties in ensuring construction quality in traditional non-decoupling dynamic compaction machinery,a range of innovative technologies for dynamic compaction construction is introduced.These include a mechanical hydraulic transmission system,dynamic stability technology for the construction arm platform,automatic compaction depth detection technology,a multi-level safety braking system for the winch,and a comprehensive control system.Through this approach,a new iteration of hydraulic-integrated non-decoupling dynamic compaction machinery has been developed.The results show that the new non-decoupling dynamic compaction machinary achieves flexible operation of starting,releasing,and start control of the hammer in the air,with the advantages of high torque,high efficiency,high stability,and high safety.Notably,practical engineering applications have shown that under the same working conditions,the construction efficiency of non-decoupling dynamic compaction machinaries using new technology is 2.5-3.0 times that of decoupling dynamic compaction machinaries.When combined with intelligent dynamic compaction monitoring systems,on-site hooking and manual measurement are not required,further improving construction efficiency and solving construction safety issues.This work can provide valuable reference for the promotion of non-decoupling dynamic compaction construction methods and the development direction of non-decoupling dynamic compaction equipment.
