Subway new and old station bottom plate joint treatment method
The invention relates to a metro new and old station bottom plate joint treatment method which comprises the following steps: chiseling off an underground diaphragm wall at the joint of a new station and an old station from top to bottom until the height difference between the chiseled-off surface of the underground diaphragm wall and the lower side surface of a bottom plate of the old station is 25-35cm; a plate structure reinforcing steel bar frame and a beam structure reinforcing steel bar frame are correspondingly arranged on the new station side and the upper side of the underground diaphragm wall, and the plate structure reinforcing steel bar frame and the beam structure reinforcing steel bar frame are connected with anchoring reinforcing steel bars in the old station bottom plate; concrete is poured on the beam structure steel bar frame and the plate structure steel bar frame, the transition beam and the new station bottom plate are correspondingly formed, the transition beam is in a T shape with the upper half portion wider than the lower half portion, and the two sides of the upper half portion of the transition beam are correspondingly pressed on the old station bottom plate and the new station bottom plate. The method has the advantages of simple process, convenience in implementation, safety and reliability.
本发明涉及一种地铁新旧站底板接缝处理方法，包括以下步骤：由上至下对新旧站连接处的地连墙进行凿除，直至地连墙凿除面与旧站底板下侧面的高度差为25～35cm；在新站侧和地连墙上侧对应设置板结构钢筋框架和梁结构钢筋框架，并使板结构钢筋框架与梁结构钢筋框架和旧站底板中的锚固钢筋连接；通过在梁结构钢筋框架和板结构钢筋框架上浇筑混凝土，对应形成过渡梁和新站底板，过渡梁呈上半部宽于下半部的T字型，过渡梁的上半部两侧对应压在旧站底板和新站底板上。具有工序简单、实施方便、安全可靠的优点。
