地下管廊管道运输吊装方案

In recent years, with the rapid development of urban underground pipelines, the demand for underground pipeline transportation and hoisting has also increased. In order to ensure the safety and quality of underground pipeline transportation and hoisting, it is necessary to formulate corresponding schemes. The following is a brief introduction to the hoisting scheme of underground pipeline transportation: 1、选择合适的设备：在进行地下管廊管道运输吊装时，要根据实际情况选择合适的起重机械设备。一般来说，可以使用手动或电动卷扬机、钢丝绳卷扬机、立式和卧式起重机、塔式起重机等。 1. Select suitable equipment: when carrying out underground pipeline transportation and hoisting, suitable lifting machinery and equipment should be selected according to actual situation. Generally speaking, manual or electric winch, wire rope winch, vertical and horizontal crane, tower crane can be used. 2、安全保障：地下管廊管道运输吊装工作要求高度安全性，因此要对各项安全保障措施进行分析。可以根据不同情况采取不同的安全保障方法：如使用特别的平衡装置来减少物体的重心;使用特别的平衡装置来减少物体的重心;使用传感器监测物体是否处于平衡态;仔细考察工作区域是否存在明显危险;如发生故障应立即停止工作。 2. Safety guarantee: Underground pipeline transportation and hoisting requires high safety level, so it is necessary to analyze all safety guarantee measures. Different safety guarantee methods can be adopted according to different conditions: using special balance device to reduce the center of gravity of objects; using special balance device to reduce the center of gravity of objects; using sensors to monitor whether objects are in balance state; carefully examining whether there are obvious dangers in the working area; stopping work immediately if any fault occurs. 3、施工方法：地下管廊管道运输吊装施工时要根据实际情况考察施工方法。一般来说可从以下几个方面考察：一是考察卸料区位于水平或者上部时如何进行上部回转作业或者水平大小回转作业?二是考察当割断或者焊接时如何将历史数据传递到新部分?三是考察当割断或者焊接时如何将历史数据传递到新部分?四是考察当零检测时如何将历史数据传递到零检测中?五是考察当零检测中出现间隔不能正常焊��时应该怎么办?六是考察当焊套中出��间隔不能正常焊 接 时 如 何 保 证 焊 接 货 物 的 合 格 等 。 3. Construction method: When carrying out construction of underground pipeline transportation and hoisting, construction methods should be examined according to actual situation. Generally speaking, it can be examined from the following aspects: firstly, how can upper rotation or horizontal small rotation operation be carried out when unloading area is located at horizontal or upper part? Secondly, how can historical data be transferred to new parts when cutting or welding? Thirdly, how can historical data be transferred into zero detection when cutting or welding? Fourthly ,how can historical data be transferred into zero detection when zero testing ? Fifthly ,what should we do if there is interval which cannot weld normally during zero testing ? Sixthly ,how can we ensure that welding goods are qualified when there is interval which cannot weld normally during welding sleeve ?
