一种沉管预制外墙支撑
摘要：
本发明涉及土木建筑施工技术领域，公开了一种沉管预制外墙支撑，其包括混凝土反力墙，固定反力架、活动反力架、驱动装置和外墙模板，所述固定反力架的一端垂直安装在所述混凝土反力墙的竖直墙面上，所述固定反力架的另一端与所述活动反力架的一端可转动连接，所述活动反力架的另一端用于顶紧所述外墙模板的内侧，所述驱动装置用于驱动所述活动反力架伸缩。本发明结构稳定、可靠，能够保证外墙模板无变形及涨模风险，且不需使用对拉螺杆，不存在螺杆孔道渗水风险。
摘要（英）：

The invention relates to the technical field of civil construction and discloses an immersed-tube prefabricated outer wall support which comprises a concrete reaction wall, a fixed reaction frame, a movable reaction frame, a driving device and an outer wall formwork. One end of the fixed reaction frame is vertically arranged on a vertical wall face of the concrete reaction wall, the other end of the fixed reaction frame is connected with one end of the movable reaction frame in a rotatable mode, the other end of the movable reaction frame is used for abutting against the inner side of the outer wall formwork, and the driving device is used for driving the movable reaction frame to stretch out and draw back. The immersed-tube prefabricated outer wall support is stable and reliable in structure, can prevent the outer wall formwork from deforming and swelling, avoids split screws and avoids the water leakage risk of screw channels.
