Construction method for dismantling old bridge by bridge girder erection machine
The invention discloses a construction method for dismantling an old bridge through a bridge erecting machine, and belongs to the technical field of old bridge dismantling. The construction method for dismantling the old bridge through the bridge erecting machine comprises the steps of land support erecting, underwater support erecting, bridge erecting machine rail support erecting, box girder blocking, bridge deck wing plate dismantling and box girder body dismantling. Under the condition that a bridge crosses a river or other spaces under the bridge are limited, the bridge can be safely and efficiently dismantled by erecting the bridge girder erection machine, the double-guide-beam bridge girder erection machine is not limited by the spaces under the bridge when being applied to bridge dismantling engineering, a beam body can be hoisted and transferred to a beam transporting vehicle section by section, the safety performance is high, the dismantling weight is large, and the flexibility is high; the device can be widely applied to various beam body dismantling engineering constructions.
本发明公开了一种架桥机拆除旧桥施工方法，属于旧桥拆除技术领域，本架桥机拆除旧桥施工方法包括：陆地支架搭设、水中支架搭设、架桥机轨道支架搭设、箱梁分块、桥面翼板拆除和箱梁体拆除。当桥梁跨河或其他桥下空间受限的情况下，通过搭设架桥机能够安全高效地完成桥梁的拆除，双导梁架桥机在桥梁拆除工程中应用可不受桥下空间限制，可将梁体逐节段吊装转移至运梁车上，安全性能搞，拆除重量大，灵活性强，可广泛用于各种拆除梁体工程施工中。
