Bridge demolition construction process
The invention relates to a bridge demolition construction process, which relates to the technical field of bridge demolition, and comprises the following steps of performing on-site reconnaissance, analyzing an on-site environment, knowing conditions of surrounding buildings and engineering facilities, and selecting a demolition method. The blasting demolition method comprises the steps of bridgedeck opening, ladder stand and scaffold erecting, hanging basket preparing, blasting point selecting, drilling, charging, blasting demolition and demolition object cleaning. The layered demolition method comprises the steps of demolition of bridge deck auxiliary structures, demolition of bridge deck pavement layers, demolition of expansion joints, demolition of beam plates, demolition of piers andcleaning of demolition objects. The layering and blasting separation demolition method comprises the steps of bridge deck appendage demolition, bridge deck pavement layer demolition, expansion jointdemolition, beam plate demolition, pier blasting demolition and demolition object cleaning. According to the bridge demolition construction process, the problem that at present, a single bridge demolition process is adopted, and for some bridges with complex structures, unique structures or unique positions, the demolition construction process reduces interference or damage to the surrounding environment.
本发明涉及一种桥梁拆除的施工工艺，涉及桥梁拆除的技术领域，包括下列步骤：现场踏勘，分析现场环境，了解周围建筑物及工程设施情况，选定拆除方法；爆破拆除方法：桥面开口，搭设爬梯及脚手架，准备吊篮，选取爆破点，钻孔、装药，爆破拆除，拆除物清理；分层拆除方法：桥面附属结构物拆除，桥面铺装层拆除，伸缩缝拆除，梁板拆除，桥墩拆除，拆除物清理；分层及爆破分离拆除方法，分层及爆破分离拆除方法包括桥面附属物拆除，桥面铺装层拆除，伸缩缝拆除，梁板拆除，桥墩爆破拆除，拆除物清理。本发明解决目前较为单一的桥梁拆除工艺，针对一些结构较为复杂，结构独特或位置独特的桥梁来讲，该拆除施工工艺降低了对周围环境的干扰或破坏。
