Prefabricated longitudinal beam of assembled and overlapped integral type underground station and construction method
The construction method comprises the following steps that the longitudinal beam is hoisted to the position above a foundation pit through a hoisting trolley, the longitudinal beam penetrates through the position between two foundation pit supports, and the longitudinal beam is controlled to rotate to be perpendicular to the foundation pit supports; the inverted-T-shaped supporting platform is adjusted till the vertical deviation rectifying steel plate is attached to the side face of the longitudinal beam, the longitudinal beam is conveyed to the position between the two stand columns through the positioning trolley, the height of the jack is adjusted, the I-shaped steel plates of the longitudinal beam and the stand columns are consistent in elevation, and the I-shaped steel plates of the longitudinal beam and the stand columns are fixed through the prefabricated connecting plates. The multi-hook-point parallel hoisting method has the beneficial effects that the stability in the hoisting process is improved by arranging multi-hook-point parallel hoisting, the horizontal distance between the longitudinal beam and the foundation pit support is pre-warned by arranging the radar sensor, it is ensured that the longitudinal beam can stably pass through the foundation pit support, collision between components is avoided, and the construction safety is improved.
本发明涉及一种装配叠合整体式地下车站预制纵梁及施工方法，包括以下步骤：将纵梁用吊装小车吊至基坑上方，将纵梁从两个基坑支撑中间穿过，控制纵梁转至与基坑支撑垂直状态；将倒T型支撑平台调整至竖直纠偏钢板与纵梁侧面贴合，定位小车将纵梁运至两立柱之间，调整千斤顶高度，使纵梁和立柱的工型钢板标高一致，通过预制连接板固定纵梁和立柱的工型钢板。本发明的有益效果是：设置多钩点并行吊装增加了吊装过程中的稳定性，并设置雷达传感器对纵梁和基坑支撑的水平距离进行预警，确保能够平稳的通过基坑支撑，避免了构件之间的碰撞，提高了施工的安全性。
