Maintenance system for box girder winter construction
The invention discloses a maintenance system for box girder winter construction. The maintenance system comprises an external heating heat preservation structure arranged on the outer side of a box girder, an internal heating heat preservation structure used for heating a box chamber of the box girder, and a temperature measuring system used for detecting the temperature of the box girder in real time; a U-shaped supporting structure is arranged on the outer side of the external heating heat preservation structure; the external heating heat preservation structure is an assembled heat preservation formwork; the cross section of the assembled heat preservation formwork is in a U shape; the assembled heat preservation formwork comprises a bottom formwork arranged at the bottom of the box girder and two side formworks symmetrically arranged on the left side and the right side of the bottom formwork; and the bottom formwork and the side formworks are all heating type heat preservation formworks. The maintenance system is novel and reasonable in design, the box girder is heated and maintained through the internal heating heat preservation structure and the external heating heat preservation structure at the same time, the situation that the temperature difference between the concrete outer surface and the concrete interior of the box girder is too large, and consequently cracks are generated on the concrete surface is effectively avoided, and the forming quality of the box girder during winter construction is guaranteed.
本发明公开了一种箱梁冬季施工用养护系统，包括设置在箱梁外侧且的外加热保温结构和用于对箱梁的箱室进行加热的内加热保温结构，以及用于对箱梁温度进行实时检测的测温系统；外加热保温结构的外侧设置有凹字形支撑结构，外加热保温结构为组装式保温模板，组装式保温模板的横截面为凹字形，组装式保温模板包括设置在箱梁底部的底部模板和两个对称设置在底部模板左右两侧的侧部模板，底部模板和侧部模板均为加热式保温模板。本发明设计新颖合理，通过采用内加热保温结构和外加热保温结构同时对箱梁进行加热养护，有效避免了箱梁的混凝土外表面和混凝土内部之间的温差过大而导致混凝土表面产生裂纹，保证了冬季施工时箱梁的成型质量。
