摘要：The current drainage pipeline repair methods present significant limitations, and this paper proposes a new construction technology applied to the internal collapse repair of high-density polyethylene (HDPE). This study designed the hot-melt, deflection, support, monitoring, and grouting mechanisms of the grouting gun body while deducing the mechanical formulas of the grouting, deflection lifting, support, and travel processes. The grouting gun body was tested by inserting it into soil, confirming that the pipe grouting robot could perform grouting in an actual construction environment. The hot-melt test verified that the hot-melt mechanism of the pipeline grouting robot melted and broke the HDPE double-walled corrugated pipe. The kinematics simulation was performed using the ADAMS software, verifying that the motion of the pipeline grouting robot satisfied the design requirements. In this paper, the dynamic simulation and experimental research of HDPE double-walled corrugated pipe grouting robot were carried out. Compared with existing drainage pipeline repair methods, the pipeline grouting and shaping technology was highly efficient in a construction environment.
