【摘要】：北京市區(qū)目前有上千公里的燃氣管線,因運行年限過長,腐蝕情況十分嚴重,急需改造。由于北京市近年來城市建設速度較快,道路上機動車數(shù)量猛增,同時地下各綜合管線不斷實施,造成原位開槽換管實施難度加大,各項非開挖修復工藝大量應用在實際改造工程中,其中翻轉內襯修復方式在實際運用過程中體現(xiàn)出了突出的優(yōu)勢。2011年市燃氣集團完成對東三環(huán)華威橋下700多米燃氣高壓管線的翻轉內襯修復。作為試驗段,該工藝經檢測完全適用于老舊高壓燃氣管道的修復工作[1],可以在高壓燃氣管線修復工作中加以推廣,通過試驗擴展了翻轉內襯工藝應用的范圍,解決了高壓管線非開挖修復的難題。然而在翻轉內襯工藝實施過程中由于受到城市管理要求制約,以及不可知因素限制,造成前期手續(xù)辦理周期較長,以及現(xiàn)場條件復雜造成施工降效情況發(fā)生,無法達到消除管線隱患的目的,因此需要對翻轉內襯工藝組織實施過程,尤其是建設單位手續(xù)辦理方面通過優(yōu)化組織機構的方式加以改進,在總結工藝實施流程經驗的基礎上,高效推進工作,確保施工工期的目的。
[Abstract]:At present, there are thousands of kilometers of gas pipelines in Beijing's urban areas. Due to the long service life, the corrosion situation is very serious, and it is in urgent need of renovation. Because of the rapid urban construction in Beijing in recent years, the number of motor vehicles on the roads has increased dramatically. At the same time, the continuous implementation of underground comprehensive pipelines, resulting in in situ slotted pipe change implementation difficulties, various non-excavation repair technology is widely used in the actual transformation project, In 2011, the City Gas Group completed the repair of more than 700 meters of high pressure gas pipeline under Huawei Bridge in East third Ring Road. The process is fully applicable to the repair of old and old high pressure gas pipelines [1], and can be popularized in the repair of high pressure gas pipelines. The scope of application of the reverse liner process is extended through experiments. The problem of non-excavation and repair of high-pressure pipeline is solved. However, due to the restriction of urban management and unknowable factors in the implementation of the overturned lining process, the pre-procedure processing period is longer. And the complex conditions of the site cause the situation of construction efficiency reduction, which can not achieve the purpose of eliminating the hidden danger of pipeline, so it is necessary to organize the implementation process of the overturned lining process. In particular, the procedures of construction units should be improved by optimizing the organizational structure. On the basis of summing up the experience of the process implementation process, the work should be advanced efficiently to ensure the purpose of construction period.
