（中建四局第六建筑工程有限責(zé)任公司， 合肥 230011）[摘要] 地下建筑的施工過程中，必然會遇到既有地下管線的改遷、就地保護(hù)等施工措施，為避免因管線拆遷對管線使用造成中斷現(xiàn)象，所以合適的就地保護(hù)措施尤為重要。本例以廣州天河體育中心綜合改造項目（第二標(biāo)段）工程，基坑南側(cè)長途光纜保護(hù)工程為例，對門式架懸吊法地下管線就地保護(hù)的施工技術(shù)進(jìn)行探討，并為此類地下管線就地保護(hù)施工提供一些值得借鑒的方法與建議。[關(guān)鍵詞] 地下建筑; 就地保護(hù); 門式架中圖分類號：TU990.3 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2013)S2-0714-03作者簡介：程群，碩士，總工程師，Email：sjchengq@cscec.com。Portal frame suspension method of underground pipeline in situ conservation constructionCheng Qun, Liu Fangling, Ye Wenjuan(China Construction 4th Engineering Bureau 6th Co. , Ltd. , Hefei 230011, China)Abstract: During the construction of underground buildings, it will certainly encounter the diversion of existing underground pipeline or in situ protection and so on. To avoid interruption phenomenon caused by the pipeline demolition, and protected in situ is particularly important. The protection of long-distance optical cable in south of the foundation pit, in Guangzhou Tianhe Sports Center Comprehensive Reconstruction Project (second section) , for example, the portal frame suspension construction technology of underground pipeline in situ conservation construction is discussed, and for this kind of underground pipeline construction in situ protection method ,we provide some worthy of reference and recommendations.Keyword: underground structure; protected in situ; portal frame
