The invention relates to a large-span high-pipe gallery internal pipeline installation construction method which comprises the steps that firstly, a protective hoisting device is installed on a pipeline truss, and after the protective hoisting device is manufactured, the protective hoisting device is arranged on the pipeline truss; secondly, a winch and a directional wheel are installed on the pipeline truss, the winch is installed on the upper portion of the pipeline truss, and the directional wheel is installed at the bottom of the pipeline truss; and thirdly, the crane moves to the preset position of the pipeline truss, the preset position of the crane is set according to the position of the winch, and butt joint installation and welding of the pipeline are started after the crane is in place. The crane has the advantages that the winch is used in cooperation, displacement of the crane is reduced, the use efficiency of the crane is improved, the situation that the landform crane is inconvenient to move is avoided, operation is convenient, applicability is high, and the construction cost is reduced; through the arrangement of the protective hoisting device, unsafe factors caused by construction in bad weather are eliminated, the construction quality and safety are guaranteed, and the method is simple and low in operation cost.
本发明涉及一种大跨度高空管廊内部管道安装施工方法,包括步骤一、管道桁架上安装防护吊装装置,制作防护吊装装置完成后,将其设置于管道桁架上;步骤二、在管道桁架上安装卷扬机及定向轮,卷扬机安装在管道桁架上部,定向轮安装于管道桁架底部;步骤三、吊车移动至管道桁架预定位置,根据卷扬机的位置设置吊车的预定位置,吊车就位之后开始进行管道的对接安装及焊接。本发明的优点是配合使用卷扬机,减少了吊车的移位、增加了吊车的使用效率,避免了地形地貌吊车不便移动的情况,操作方便、适用性强,降低了施工成本;通过设置的防护吊装装置,排除了不良天气施工带来的不安全因素,保障了施工质量和安全,本发明方法简单,操作成本低。
