Prefabricated underground comprehensive pipe rack and construction method
An embodiment of the invention discloses a prefabricated underground comprehensive pipe rack. The prefabricated underground comprehensive pipe rack comprises a comprehensive pipe rack singe body, connecting assembly and a supporting structure used for supporting the comprehensive pipe rack single body, wherein the comprehensive pipe rack single body is arranged on a pipe rack foundation. A construction method comprises following steps: step 100, supporting sleeves are inserted into selected comprehensive pipe rack mounting positions, and an underground passage is excavated after the supportingsleeves are inserted; step 200, the supporting sleeves are pulled out gradually after the underground passage is excavated, supporting sleeve columns are formed by pouring after the supporting sleeves are pulled out, and a supporting structure is constructed with the supporting sleeves as the base; step 300, an upper pipe rack section is laid on the formed supporting structure, a middle pipe racksection is laid with the lower pipe rack section as a passage, and an upper pipe rack section is mounted with a regression method; and step 400, the assembled comprehensive pipe rack is subjected tosecondary sealing processing. Accessory structures such as the pipe rack foundation are constructed while the supporting structure is built, so that functions of the pipe rack are reduced, and dead weight of the pipe rack and economic cost of construction are reduced.
本发明实施例公开了一种装配式地下综合管廊，包括综合管廊单体和连接组件、以及用于支撑所述综合管廊单体的支护结构，所述综合管廊单体设置在廊基上；该施工方法，包括如下步骤：步骤100、在选定综合管廊安装位置打入支护套筒，在打入支护套筒后挖掘地下通道；步骤200、在地下通道挖掘完成后逐次拔出支护套筒，拔出支护套筒后浇筑形成支护套柱，以支护套柱为基础建立支护结构；步骤300、在形成的支护结构上铺设廊管下段，以廊管下段作为通道铺设廊管中段，并以退步法安装廊管上段；步骤400、对装配后的综合廊管进行二次密封性处理；本发明通过构建支护结构的同时建立廊基等附属结构，削减了管廊的功能，降低了管廊的自重和施工建设的经济成本。
