摘要

水平定向穿越管道起吊过程中,管道的吊点位置决定管道入土角度,如入土角度偏大或者偏小,都可能导致管道在入土时发生卡管或瘪管事故。通过对管道起吊过程的受力分析,结合材料力学知识,得到管道的吊点位置与入土角度的数学模型,并利用实验研究验证其准确性。研究表明吊点2的位置对入土角度的影响比吊点1敏感。实验结果与理论计算结果的相对误差是5.8%,表明该数学模型可用于现场指导。

Abstract

If the hoisting position is bad during the engineering application of the lifting pipe,which may bring the serious influence when the pipe smoothly enters the grave,even happen stuck pipe and tube flat accidents. Through the mechanical analysis of the pipe lifting,themathematical model about lifting point position and the grave angle was established,which on the basis of reasonable assumptions. The location of the lifting point 2 affects on the size of the grave angle more than lifting point 1by mathematical model analysis. And then compared with the calculated value of mathematical model and the value of test measurement,the relative error of theoretical calculation value and experimental value that is about 5. 8% was discovered.Therefore,the mathematical model can be used to guide the actual construction.
