Low-noise forcible entry method for simply supported prestressed hollow slab bridge
The invention particularly relates to a low-noise forcible entry method for a simply supported prestressed hollow slab bridge. The method comprises the following steps: 1, marking hinge joint positions between transverse and longitudinal hollow bridge plates; 2, mounting color strip cloth on the full bridge in a span division manner; 3, assembling a sound insulation, protection and dust reductionintegrated device; 4, breaking the longitudinal hinge joints of the bridge plate from one end of the bridge; 5, hoisting out the bridge plates through a crane after the bridge deck system and the hinge joint are cleaned; 6, carrying out fretsaw cutting on a bent cap and a pier stud, lifting out the bent cap and the pier stud, transporting the bent cap and the pier stud to a crushing plant far awayfrom an urban area together with the span bridge plate, and carrying out unified breaking; and 7, removing broken objects on the color strip cloth and removing the color strip cloth. A shielding cover with the sound insulation and cover cap functions covers a breaking hammer body, so that the sound insulation and dust prevention functions are achieved in the working process of the breaking hammerbody, thereby the problems that in the bridge breaking process, noise is large, and dust flying is serious are solved from the source.
本发明具体是一种简支预应力空心板桥梁的低噪音破拆方法；步骤1、标出横向、纵向空心桥板之间的铰缝位置；步骤2、在全桥分跨安装彩条布；步骤3、组装隔音防护降尘一体化装置；步骤4、从桥梁一端开始破除桥板纵向铰缝；步骤5、桥面系及铰缝清理完成后，采用吊车对桥梁板进行吊出；步骤6、对盖梁及墩柱进行线锯切割并吊出和本跨桥板一起运到远离市区的破碎厂，进行统一破除；步骤7、清理彩条布上的破除物及拆除彩条布。本发明通过在破碎锤上罩设一个带有隔音和罩盖功能的遮挡罩，从而在破碎锤工作过程中起到隔音和防尘的功能，从而在源头上解决桥梁破拆过程中噪音大、粉尘飞扬严重的问题。
