一、在桥孔上灌筑钢筋混凝土梁的特点钢筋混凝土梁在桥孔上灌筑具有下列优点: (一)可化整为零,普遍开花,施工单位在作桥的下部工程的同时即可着手安排灌筑工作,使劳动力能得到合理的调剂。 (二)在桥墩台的施工过程中对大堆料已有了充分的调查和试验,掌握了第一手资料,为灌注好梁打下了基础,而且各种材料都在工地,灌注梁时可以利用。 (三)风、水、电路都畅通,灌注梁时无 First, the bridge hole perforated reinforced concrete beam characteristics Reinforced concrete beams in the bridge hole filling has the following advantages: (A) can be adjusted to zero, the general flowering, the construction unit for the bridge at the same time as the lower part of the project can proceed with the arrangements Sinking work, so that the labor force can be a reasonable adjustment. (B) of the piers in the construction process of a large pile of material has been fully investigated and tested, grasp the first-hand information to lay a good foundation for the infusion of beams, and a variety of materials are at the site, when the beam can be perfusion use. (C) the wind, water, circuit are smooth, perfusion beam no
