Construction method for downwards penetrating existing municipal pipeline through multiple flexible sleeves
The invention discloses a construction method for a plurality of flexible sleeves to downwards penetrate an existing municipal pipeline, which is characterized by comprising the following steps of: excavating a soil body within a path range of one flexible sleeve, forming a mounting channel, and arranging a support frame in the mounting channel; excavating the soil body in the path range of the other flexible casing pipe, forming the mounting channel, arranging a supporting frame in the mounting channel, and repeating the steps until all the flexible casing pipe paths are excavated; after the supporting frame in one mounting channel is removed, a flexible sleeve is arranged in a penetrating mode, and gaps between the outer wall of the flexible sleeve and the inner wall of the mounting channel are backfilled; the steps are repeated until all the flexible sleeves are installed; according to the method, the excavation face is ensured to be stable in the mode that the supporting frame replaces the excavated earthwork, then the supporting frame is taken out, meanwhile, the newly-constructed flexible casing pipe is inserted, backfilling and compacting are conducted, and the pipeline construction mode is completed, and on the premise that normal operation of the current pipeline is ensured, flexible pipeline construction is completed safely, efficiently and rapidly.
本发明公开了一种多条柔性套管下穿既有市政管道的施工方法，其特征在于，包括以下步骤：开挖其中一条柔性套管路径范围内的土体并形成安装通道，在所述安装通道内设置支撑框；开挖另外一条柔性套管路径范围内的土体并形成所述安装通道，在安装通道内设置支撑框，重复上述步骤，直至所有的柔性套管路径开挖完毕；拆除其中一条安装通道内的支撑框后穿设柔性套管，将所述柔性套管外壁和所述安装通道内壁之间的缝隙进行回填；重复上述步骤，直至所有的柔性套管安装完毕；本发明采用支撑框置换开挖土方的方式确保开挖面稳定，然后在取出支撑框的同时插入新施工的柔性套管并回填密实完成管道施工的方式，在确保现状管道正常运营的前提下，安全、高效、快速的完成柔性管道施工。
