Quick dismantling method for municipal flyover
The invention discloses a quick dismantling method of a municipal flyover, which comprises the following steps: totally-closed management is carried out, the design positions of left and right web lines of a box girder are drawn, and a crawler-type rock drill is in place for the first time; concrete at the positions of a crash barrier and a wing plate of the overpass box girder is chiseled away in a symmetrical chiseling operation mode; the crawler-type rock drill is in place for the second time on the ground; each span of the box girder is provided with four crawler-type rock drills to symmetrically chiseling away two ends of the box girder, when the two ends of the box girder are damaged, the whole span of the box girder can collapse to the ground, and the crawler-type rock drills chiseling away the box girder and transporting materials away from the site. A plurality of crawler-type rock drills are adopted to carry out chiseling operation at the same time, chiseled concrete residues are transported away from the site in time, the whole flyover can be dismantled in a short time, the problems that the municipal flyover is long in dismantling construction period, tedious in blasting procedure and limited in use are solved, and transportation of citizens is not affected.
本发明公开了一种市政立交桥的快速拆除方法，全封闭管理，画出箱梁左右腹板线的设计位置，履带式凿岩机按第一次就位；采用对称凿除作业的方式，凿除立交桥箱梁的防撞栏跟翼板位置的混凝土；履带式凿岩机在地面进行第二次就位；每跨箱梁安排四台履带式凿岩机对称凿除箱梁的两个端头，当箱梁的两个端头被破坏后，使整跨箱梁会垮塌到地面上，履带式凿岩机凿除箱梁并将材料运离现场。采用多台履带式凿岩机同时进行凿除作业并将凿除的混凝土渣及时运离现场，很短时间就能使整座立交桥完成拆除，解决了市政立交桥拆除工期长、爆破手续繁琐及使用受限的问题，并且不影响市民交通出行。
