Urban underground comprehensive pipe gallery and construction method thereof

WANG BOCHAO

The invention discloses an urban underground comprehensive pipe gallery and a construction method thereof, relates to the technical field of urban comprehensive pipe networks. The problem that in theprior art, the modes such as foundation treatment, ditching and sand filling and flexible joints are adopted to reduce the damage of ground cracks to underground pipelines but the effect is poor is solved. The urban underground comprehensive pipe gallery comprises multiple pipe sections, wherein the multiple pipe sections comprise multiple first pipe sections, at least one second pipe section andat least two connecting pipe sections, the shape of each second pipe section is the same as the shapes of the first pipe sections, and the sectional area of each second pipe section is larger than thesectional area of each first pipe section; and the connecting pipe sections connect the second pipe sections with the first pipe sections.

本发明公开一种城市地下综合管廊及其施工方法，涉及城市综合管网技术领域，用于解决现有技术中采用地基处理、砌沟填砂、柔性接头等方式来减少地裂缝对底线管线的损害但其效果较差的问题。本发明的城市地下综合管廊，包括多个管节，所述多个管节包括：多个第一管节；至少一个第二管节，所述第二管节和所述第一管节的形状相同、且所述第二管节的截面面积大于所述第一管节的截面面积；至少两个连接管节，所述连接管节将所述第二管节与所述第一管节连接。
