Construction method of full-section prefabricated corridor under aggregate stockpiling site
The invention discloses a construction method of a full-section prefabricated corridor under an aggregate stockpiling site. The construction method comprises the following steps: 1, prefabricating a plurality of groups of prefabricated wall plate groups and a plurality of prefabricated top plates; 2, excavating a gallery foundation and constructing a cast-in-place bottom plate; 3, erecting a scaffold on the boss; fourthly, the prefabricated side wall plates are hoisted, the inner side faces of the prefabricated side wall plates abut against the bosses, and each prefabricated wall plate set is temporarily stabilized through a scaffold; 5, mounting a prefabricated top plate, and pouring a fixed wall; sixthly, the scaffold is dismantled, and an earth and stone backfilling layer is backfilled The whole section of the gallery adopts the prefabricated wallboards, the work amount of formworks and bearing frames for cast-in-place concrete construction is greatly reduced, the construction cost is reduced, the construction safety risk is reduced, the top plates of the side walls of the gallery are prefabricated and installed in a segmented and blocked mode, a plurality of short stress units with independent sections are formed in the length direction of the gallery, and the construction safety is improved. Harmful structural cracks caused by differential settlement of the gallery bottom plate foundation can be effectively prevented, and the structure is safe and reliable.
本发明公开了一种骨料堆存场地下全断面预制廊道施工方法，包括步骤：一、预制多组预制墙板组和多个预制顶板；二、廊道基础开挖并构筑现浇底板；三、凸台上搭设脚手架；四、吊装预制侧墙板，使预制侧墙板的内侧面与凸台抵接，并利用脚手架对每组预制墙板组进行临时稳固；五、安装预制顶板，并浇筑固定墙；六、拆除脚手架并回填土石回填层。本发明廊道全断面采用预制墙板，大幅减小了现浇混凝土施工的模板和承重架的工程量，施工成本降低，减小了施工安全风险，廊道侧墙顶板分段、分块预制安装，在廊道长度方向上形成多个较短的独立断面的受力单元，可以有效防止由于廊道底板地基不均匀沉降产生的结构有害裂缝，结构安全可靠。
