Multi-span prestressed concrete continuous beam bridge dismantling method
The invention discloses a method for dismantling a multi-span prestressed concrete continuous beam bridge. The method comprises the steps of dismantling bridge deck accessories, milling bridge deck asphalt through a milling vehicle and transporting the bridge deck asphalt outwards, converting a bridge deck system, dismantling a beam body structure and transporting crushed concrete slag outwards. According to the device, a conventional structure of an existing multi-span prestressed concrete continuous beam bridge is combined, aiming at structural characteristics of an old precast beam bridge, a construction method of in-situ breaking or static dismantling is adopted, the dismantling step is completed span by span, the existing precast beam bridge is safely and rapidly dismantled, a set of complete construction method is provided for dismantling of the bridge, and the construction period is shortened. Reference is provided for similar projects, and the method has extremely high popularization value.
本发明公开了一种多跨预应力混凝土连续梁桥拆除方法，包括拆除桥面附属，将桥面沥青采用铣刨车铣刨并外运，桥面体系转换，梁体结构拆除，破碎砼渣外运。本装置结合现有的多跨预应力混凝土连续梁桥的常规结构，针对预制梁旧桥的结构特征，采用破碎机械原位破除或者静力拆除的施工方法，逐跨完成拆除的步骤，安全快速的拆除既有预制梁桥，为桥梁的拆除提出一套完整的施工方法，为类似工程提供借鉴，具有极高的推广价值。
