Underground excavation construction method for underground multi-cabin utility tunnel underpass buildings
The invention belongs to the technical field of pipe gallery construction, and particularly relates to an underground excavation construction method for underground multi-cabin utility tunnel underpass buildings. A utility tunnel is prefabricated in a factory by adopting segment prefabrication and assembly, a formwork system adopts a customized complete set of steel formwork and vertical pouring,the outer wall of a steel structure outer mold is a steel plate, the interior of the steel structure outer mold is of steel truss structure; the outer wall of a steel structure inner mold of each cabin is a steel plate, and the interior of the steel structure inner mold is of steel truss structure. According to the weight of different segments, different lifting points are adopted, a underground multi-cabin utility tunnel is formed by splicing prefabricated reinforced concrete utility tunnel segments through adhesives and tensioning the prefabricated reinforced concrete pipe gallery sections in a prestress mode, the adhesives play a role in adhesion and achieve the effects of filling, sealing, seepage resistance, leveling and the like. The method has the advantages of being high in stability, high in construction speed and the like, the construction quality can be guaranteed, the safety of existing buildings is guaranteed, and smooth proceeding of follow-up crossing construction is guaranteed.
本发明属于管廊施工技术领域，特别是涉及一种地下多舱管廊下穿建筑物的暗挖施工方法，管廊采用节段预制拼装，在工厂内预制，模板系统采用定制成套钢模板，立式浇注，所述钢结构外模的外壁为钢板，所述钢结构外模的内部为钢桁架结构。所述各舱室钢结构内模的外壁为钢板，所述钢结构内模的内部为钢桁架结构.根据不同的节段重量，采用不同的吊点设置，地下多舱管廊由预制钢筋混凝土管廊节段通过胶粘剂拼接、预应力张拉而成，胶粘剂除了起到粘结作用外，还起到填充、密封、抗渗和找平等作用。本发明方法具有稳定性高、施工速度快等优势，而且能保证施工质量，确保已有建筑物安全，保障后续穿越工作顺利进行。
