Demolition construction method for existing river channel-crossing prestressed concrete bridge
The invention discloses a demolition construction method for an existing overpass river channel prestressed concrete bridge, and the method comprises the following specific steps: S100, carrying out the detailed detection and evaluation of the condition of the bridge, determining the condition of a bridge structure, and evaluating the demolition difficulty of the bridge; s200, carrying out simulation calculation on bridge demolition so as to determine an optimal segmented cutting demolition scheme, and determining the position of a first cutting point; s300, the prestress of the bridge is gradually released through professional equipment and technology, the internal stress of the bridge structure is adjusted, and the structure instability risk caused by sudden dismantling is reduced; s400, cutting the bridge from the position of the first cutting point according to a dismantling scheme of bridge simulation calculation, hoisting a part to be cut and removed by using hoisting equipment while cutting, and directly hoisting the part to a specified position by using the hoisting equipment after cutting is completed; when the bridge is cut, the cutting flatness and precision of the bridge sections need to be ensured.
本发明公开了一种既有上跨河道预应力混凝土桥梁的拆除施工方法，该方法的具体步骤如下：S100、对桥梁的情况进行详细的检测和评估，确定桥梁结构的状况，并对桥梁的拆除难度进行评估；S200、对桥梁拆除进行模拟演算，从而确定最佳的分段切割拆除方案，并且确定第一切割点的位置；S300、采用专业的设备和技术对桥梁的预应力进行逐步的释放，桥梁结构的内部应力得到调整，减少了因突然拆除而导致的结构失稳风险；S400、根据对桥梁模拟演算的拆除方案，从第一切割点的位置对桥梁进行切割，并且在切割的同时利用起重设备对即将切割去除的部分进行起吊，切割完成后由起重设备直接吊运到指定位置；对桥梁切割时要确保桥梁分段处切割的平整度和精度。
