Dismantling method of inverted siphon bridge cable hoisting device under steep and narrow working condition
The invention relates to the technical field of bridge construction, in particular to a dismantling method of an inverted siphon bridge cable hoisting device under steep and narrow working conditions, which comprises the following steps: step 1, dismantling a main hoisting point and a main rope; 2, arranging a double-layer temporary cable; 3, reinforcing and protecting the truck crane; fourthly, the main cable saddle is dismantled; 5, adjusting the temporary cable wind; 6, unloading the structure cable wind; seventhly, the tower top profile steel distribution beams are dismantled; eighthly, a cable bent tower assembling frame is installed; ninthly, the transverse connectors at the main pipes are dismantled; tenthly, a follow-up support is dismantled; eleventhly, the truck crane standard section is lowered; and twelfthly, layer-by-layer dismantling is conducted according to the steps, and the double-layer temporary cable wind moves downwards alternately layer by layer. The dismounting device has the effect that the dismounting procedure of the inverted siphon bridge cable hoisting device is simplified, so that the dismounting efficiency of the cable hoisting device is improved.
本申请涉及桥梁施工技术领域，尤其是涉及一种陡峭狭窄工况的倒虹吸管桥缆索吊装装置的拆除方法，其包括以下步骤：步骤一、主吊点、主绳拆除；步骤二、布置双层临时缆风；步骤三、加固防护汽车吊；步骤四、拆除主索鞍；步骤五、调整临时缆风；步骤六、卸载结构缆风；步骤七、拆除塔顶型钢分配梁；步骤八、安装索塔拼装架；步骤九、拆除主管处横联；步骤十、拆除后续支架；步骤十一、降低汽车吊标节；步骤十二、按上述步骤进行逐层拆除，双层临时缆风逐层交替下移。本申请具有简化倒虹吸管桥缆索吊装装置的拆除程序，以提高了缆索吊装装置的拆除效率的效果。
