东北地区泥水平衡盾构施工营地标准建设

Camp Building of Slurry Balanced Shield Construction in Northeast China

长岭—长春—吉化输气管道工程属于东北天然气管网的一部分,其中长春—吉化段第二松花江穿越采用泥水平衡盾构工法。目前,这是国内最高纬度泥水平衡盾构施工,场地建设具有地理位置的特殊性,无以往施工经验可借鉴。工程场地建设针对东北冬季低温气候条件以及泥水平衡盾构施工工艺要求,考虑周全、细致,功能分区合理,并多次进行专家论证,采取各方面措施进行防冻保温,为后期盾构施工的顺利进行提供了便利条件和有效保障。

The gas transportation projet of Changling-Changchun-Jihua is a part of gas pipeline of northeast China.The Changchun-Jihua segment crosses No.2 Songhuajiang.Slurry balanced shield method is adopted,which is the application of slurry balanced shield in the largest latitude in China.So the camp building has its special characteristics and no experience of similar project.The camp is built according to low temperature in winter of northeast China and process demands.All the factors are considered.The division of function is reasonable.By several times of professor demonstrate,heat preservation measures are used to provide conditions for successful construction.
