Urban comprehensive pipe gallery construction method

YANG JIAYAN

The invention discloses an urban comprehensive pipe gallery construction method and belongs to the technical field of pipe gallery construction.The urban comprehensive pipe gallery construction method comprises the steps that a pipe gallery structure prefabricated block with the bottom open is prefabricated, the prefabricated block comprises a side plate and a top plate, and the side plate and the top plate are integrally formed; after the foundation pit is excavated, a plurality of longitudinal beams are poured at the bottom of the foundation pit in the length direction of the foundation pit, the longitudinal beams correspond to the side plates of the precast blocks one to one, and an advancing channel for supporting the trolley is formed between the longitudinal beams; a supporting trolley walking along the walking channel is arranged, the precast blocks are hoisted and extensively placed on the supporting trolley, the supporting trolley drives the precast blocks to complete splicing, and splicing comprises splicing of the side plates and the longitudinal beams and end connection of the adjacent precast blocks; and after assembly is completed, waterproof treatment is conducted, backfilling and earthing can be conducted after waterproof treatment is completed, and then foundation pit bottom construction treatment is conducted. According to the construction method, the splicing efficiency can be improved, and the construction period is effectively shortened.

本发明公开了一种城市综合管廊施工方法及施工方法，属于管廊施工技术领域，包括：预制底部敞开的管廊结构预制块，所述预制块包括侧板和顶板，侧板与顶板一体成型；基坑开挖完成后，在基坑底部沿基坑长度方向浇筑若干纵梁，纵梁与预制块的侧板一一对应，纵梁之间形成支撑台车的行进通道；设置沿行进通道行走的支撑台车，将预制块吊装粗放在支撑台车上，由支撑台车驱动预制块完成拼接，拼接包括侧板与纵梁的拼接以及相邻预制块的端接；拼装完成后，进行防水处理，完成后即可回填覆土，再进行基坑底部施工处理。本发明的施工方法可以提高拼装效率，且有效缩短工期。
