Construction technology for installing directly-buried-section reinforced concrete drainage pipelines
The invention relates to a construction technology for installing directly-buried-section reinforced concrete drainage pipelines. During pipe laying operation, a lifting arm on single pipelines is adopted for hoisting the single pipelines in a storage box into a pipe pit at a time, and therefore, the construction technology shortens the time for erecting a crane compared with the mode of using thecrane, and is labor-saving and high in efficiency compared with the mode of manual pipe laying operation. In addition, the situation that when drainage pipelines are arranged at the two sides of thepipe pit in the length direction of the ditch pipe pit in advance, the drainage pipes may be insufficient or excessive is also avoided, and the construction efficiency is furthermore improved. An earth fill mechanism follows pipeline installing equipment to move and pushes mounds at the two sides of the pipe pit into the pipe pit to position the single pipelines, thus stability of the single pipelines is maintained, and deviation of the directly-buried section is avoided. After all the single pipelines are laid, pipe pit backfilling can be carried out after the airtightness of the single pipelines is judged by means of a closed water test, and then installation of the directly-buried-section reinforced concrete drainage pipelines is completed.
本发明涉及一种直埋段钢筋混凝土排水管道安装施工工艺，下管作业时通过管道单体上的起吊臂一次将存储箱内的管道单体吊装至管坑内，从而相比现有的通过起重机的方式减少了起重机架设的时间，并且相比人工下管的方式，更加省力快捷，也避免了预先将排水管道沿沟管坑长度方向排列于管坑两侧可能出现的排水管数量不够或过多的情况，进一步提高了施工效率。填土机构跟随管道安装设备运动并将管坑两侧的土堆推入管坑中对管道单体进行定位，从而保持管道单体的稳定，避免直埋段偏离。当所有管道单体下装好后，通过闭水实验判断管道单体的密封性后即可进行管坑回填，完成对直埋段钢筋混凝土排水管道的安装。
