Experimental Quantification of Load-bearing Mechanisms in Spiral Wound Lining Rehabilitation of HDPE Pipes
摘要
Abstract
A plate-loading test platform was established to conduct mechanical tests on both original and rehabilitated pipe specimens,and the mechanical behavior of high-density polyethylene(HDPE)pipes rehabilitated using the spiral wound lining(SWL)method was investigated.The results show that,for pipelines rehabilitated with SWL technology,when the inner diameter deformation was controlled within 5%,the vertical load-bearing capacity of pipes increased by 246%.The grouting layer and the liner contributed 91%and 9%,respectively,to this enhancement in vertical load-bearing capacity.When loading continued until the grouting layer cracked and failed,its contribution to the improvement of the vertical load-bearing capacity of the composite pipe section decreased significantly.When the vertical loading displacement reached 200 mm,the contribution rates of the grouting layer and the liner were 44%and 56%,respectively.The experiments further revealed that the liner,through interfacial friction,effectively enhanced the confinement effect at the pipe-grout interface,prevented and reduced relative slippage of the grouting layer,and ensured the overall stability of the composite pipe during the instability-failure stage.关键词
