Construction method for variable cross-section T-shaped joint top plate of space-limited corridor
The invention relates to a construction method for a variable cross-section T-shaped connector top plate of a space-limited corridor. The construction method comprises the steps that a four-pipe-column supporting system and a steel beam are installed in the corridor, a wood bottom die is laid, and a supporting platform is constructed; an inner mold for forming the corridor variable-cross-section wall body is installed; mounting a cantilever type support-free local disassembly-free steel bottom die; mounting a hoisting ring for dismounting the steel beam; binding structural steel bars at the gallery top plate and the gallery variable cross-section wall body; mounting an outer mold for forming the gallery variable cross-section wall body and an outer mold for forming the gallery top plate; pouring concrete; concrete curing is conducted till the concrete strength reaches the design strength; and dismantling. On the premise of completing construction with quality and quantity guaranteed, the construction efficiency is improved, the construction progress is accelerated, the problem of roof construction with the limited gallery space is solved, and meanwhile it needs to be guaranteed that a reverse power transmission related medium-voltage cable path is smooth.
本发明涉及一种空间受限廊道变截面T型接头顶板施工方法，包括在廊道内安装四管柱支撑体系和钢梁，铺设木底模，构建支撑平台；安装廊道变截面墙体成形的内模；安装悬臂式无支撑局部免拆钢底模；安装钢梁拆除用吊环；对廊道顶板及廊道变截面墙体处进行结构钢筋的绑扎；安装廊道变截面墙体成形的外模、廊道顶板成形的外模；浇筑混凝土；进行混凝土养护，至混凝土强度达到设计强度；拆除。本发明能够在保质保量完成施工的前提下，提高施工效率，加快施工进度，不仅解决廊道空间受限顶板施工问题的同时需保障倒送电相关中压电缆路径通畅。
