【摘要】：在土木工程建设的十几年以来,由于我国的土木交通工程运输事业的不断发展,使我国的一大批跨度连续梁呈现发展的趋势,但是如何确保连续梁在施工过程中的安全性与准确度,成为一个非常关键的问题。因此连续梁的施工监控技术就非常重要。在预应力管道注浆施工中,注浆质量主要依靠施工队伍经验和职业操守来控制管道注浆压力、屏浆时间和注浆质量等,同时注浆施工记录依靠人工进行记录,注浆施工随意性大、可溯源性差、数据可靠性差。预应力管道注浆不密实,在桥梁建成后,即使发现管道注浆质量不良补救也十分困难。智能张拉与压浆设备的出现,则是上述问题得到一定的解决。本文研究对象就是针对在智能张拉与压浆施工工艺下的连续梁悬臂施工监控技术的研究,该研究不但开发出精确的智能张拉与压浆系统与设备,而且对该桥的施工监控技术进行了实践应用,从而说明了智能张拉压浆技术在连续梁悬臂法施工中具有很好的可行性。
[Abstract]:In the past ten years of civil engineering construction, due to the continuous development of civil engineering and transportation in China, a large number of span continuous beams in our country have shown a trend of development. However, how to ensure the safety and accuracy of continuous beam in construction process has become a key issue. Therefore, continuous beam construction monitoring technology is very important. In prestressed pipeline grouting construction, grouting quality mainly depends on construction team experience and professional conduct to control pipeline grouting pressure, grouting time and grouting quality, while grouting construction records are recorded manually. Grouting construction random, poor traceability, poor data reliability. After the bridge is built, it is very difficult to remedy the poor grouting quality even if the grouting quality of the prestressed pipeline is not dense. The emergence of intelligent tensioning and grouting equipment is a solution to the above problems. The research object of this paper is to study the cantilever construction monitoring technology of continuous beam under intelligent tensioning and grouting construction technology. This research not only develops the accurate intelligent stretching and grouting system and equipment, Moreover, the construction monitoring technology of the bridge is applied in practice, which shows that the intelligent tensioning and grouting technology is feasible in the construction of continuous beam cantilever method.
