Reverse construction method for large-diameter pipeline of comprehensive pipe gallery
The invention discloses a reverse construction method for a large-diameter pipeline of a comprehensive pipe gallery, which is used for solving the problem of installation of the large-diameter pipeline in the comprehensive pipe gallery and comprises the following steps of pipeline blanking, pipeline transportation, temporary supporting and fixing of the pipeline, pipeline welding and buttress concrete pouring, welding is conducted through temporary supporting and fixing, then pouring is conducted through concrete, the problem that in a traditional method, the welding difficulty in the pipe gallery is large is solved, the welding quality can be guaranteed, due to post-pouring, blocking of buttresses is avoided in the pipe conveying process, and the pipe conveying process is smoother. According to the construction method, the traditional machining sequence is changed, and the special pipe conveying trolley is matched, so that the layout of the large-diameter pipeline in the comprehensive pipe gallery is greatly simplified, and the production efficiency is improved.
本发明公开了一种综合管廊大直径管道的逆序施工方法，用于解决综合管廊中大直径管道的安装问题，包括以下步骤：管道下料、管道运输、管道临时支撑固定、管道焊接、支墩混凝土浇筑，其中浇筑与焊接安装的施工顺序进行交换，通过临时支撑固定进行焊接，再用混凝土进行浇筑，也就避免了传统方法中管廊内焊接难度较大的问题，能够保证焊接质量，而且由于后浇筑，在运管过程中就不会受到支墩的阻挡，运管过程更加顺畅。本发明的施工方法通过改变传统的加工顺序，配合专用的运管小车，大大简化了大直径管道在综合管廊的布设，提高了生产效率。
