摘　　要：在椰海大道管廊给水工程施工中,由于管道设计与管廊设计不是同一家设计单位而造成对预留吊装口的不同设计方案,导致管廊预留吊装口狭小。阐述了在工程总体工期不变的情况下,研究采用12 m长的钢管用双钩斜吊法吊入7 m长的预留吊装口内的操作方法,通过对实际案例进行分析,证明了双钩斜吊法在管廊狭窄吊装口中吊装的可行性和实用性,极具推广价值。In the construction of water supply engineering of Yehai Avenue pipeline corridor,the different design schemes of the reserved hoisting opening are caused by the difference of the pipeline design and the pipeline corridor design,which results in the narrow reserved hoisting opening of the pipeline corridor.This paper expounds the operation method of lifting steel pipe of 12 m into 7m reserved hoisting hole by double hook inclined lifting method under the condition that the overall construction period of the project is unchanged.Through the analysis of actual cases,the feasibility and practicability of double hook slanting lifting method in the narrow hoisting mouth of pipe gallery are proved,which is worth popularizing.
