摘要
贝雷片拼装双导梁技术通常是应用于大跨度桥梁的梁片吊装中的。论述的工程经过施工人员精密的理论计算 ,在国内首次将双导梁技术大胆地应用在中断顶进涵工程中 ,获得成功。工程施工实践经验表明 :此法适合于铁路、公路吊机无法施工的装吊作业 ;或受地形限制 ,工程量不多 ,设备不易进场的情况下 ,提高了施工作业的安全性 ,其优势十分显著。
The technique of patchwork double leads girder hoisting by beret pieces usually suitable for large-span bridge girder hoist construction. This paper introduces through exact academic theory calculation by construction workers, this is bravely use double leads girder in the Central Relay Culvert Project first time in home country ,and make a big success.The construction practice experience of this project in dicates that the method has a lot of advan tages:it suitable for the hoisting work of cannot construction on the road and railway .Or under the circumstances of the equipment enter the building site difficultly,the quantity of less projects,the restriction of terrain.More importantly ,it improves the safety of construction task .
