摘　　要：武汉书轨道交通11号线三期葛店段工程土建工程在施工过程中,需对中板预留洞口进行封堵,但不能影响区间隧道掘进电瓶车出土施工,需要在其中板下方预留出盾构出土车运行空间,设计并搭设了满堂碗扣式支架门洞支架,支架立杆采用双钢管进行搭设,提高其刚度及稳定性,达到浇筑的目的,从而保证了盾构施工进度和主体结构施工进度。该项目运用此方案成功浇筑完混凝土,取得了预期的目的。根据施工现场实践,就该门洞式支撑体系的设计结构、设计应用和应用情况进行阐述,可为相似工程提供借鉴和参考。During the construction of the civil engineering of Gedian Section of Wuhan Rail Transit Line 11 Phase III,it is necessary to block the reserved hole in the middle plate,but it should not affect the excavation of the battery car for tunnel excavation in the section.It is necessary to reserve the operation space of the shield excavator under the middle plate.It is designed and erected a full bowl shaped bracket for the door opening.The vertical pole of the bracket is erected with double steel pipes to improve its stiffness and stability and achieve the purpose of pouring,so as to ensure the construction progress of shield machine and main structure.The project has successfully poured concrete with this scheme and achieved the expected purpose.According to the construction site practice,the design structure,design application and application of the portal support system are described,which can provide reference for similar projects.
