【摘要】：在国内外淡水资源越来越缺乏的情况下,大型海水资源利用项目在国内外逐渐展开,超大型玻璃钢输水管道的应用势在必行。作为一种新型的建筑管材,玻璃钢管道凭借其优异的性能被广泛应用于建筑工程当中,带来了显著的经济效益,其市场前景和发展潜力是不可估量的。目前为止,国内玻璃钢管道的施工方法都是参照其他材质的管道,并没有针对超大型玻璃钢管道施工方法的研究,基于这种现状,本文结合沙特阿拉伯朱拜勒工业区海水冷却水取水整体项目的二期工程,对超大型玻璃钢管道的施工工艺进行针对性研究,希望为其它超大型玻璃钢输水管道项目的施工提供借鉴和指导。本文主要的研究内容包括:(1)从管道安装对口施工、工作管穿过路套管施工、防漂管施工、阀门井预埋套管施工四方面入手,通过理论分析和计算,提出超大型玻璃钢输水管道的施工方案;(2)对提出的施工方案进行试验,包括场外试验和典型施工段试验,进而验证施工方案的可行性;(3)通过分析试验中存在的问题,对施工方案进行相应改进;(4)结合本工程,对超大型玻璃钢输水管道的施工工艺进行总结。通过本文的研究,主要得出以下结论:(1)超大型玻璃钢管道的管径较大,在进行管道安装对口施工时,必须考虑吊装、运输、变形以及对接准确性等方面的因素;(2)超大型玻璃钢管道长度较长,自重较大,在进行工作管穿过路套管施工时,应特别注意管道的变形和移位;(3)超大型玻璃钢管道的浮力较大,在进行防漂管施工时无法采用传统压沙袋法,所以在施工中要做好降水措施;(4)在进行超大型玻璃钢管道阀门井施工时,应特别注意法兰短管对接就位的准确性。本文的研究成果已经成功应用于实际工程,对于其它超大型玻璃钢管道项目的施工具有良好的借鉴和指导作用。
[Abstract]:With the shortage of fresh water resources at home and abroad, large-scale sea water resources utilization projects are gradually launched at home and abroad, and the application of super large FRP water conveyance pipeline is imperative. As a new type of building pipe, FRP pipe has been widely used in construction engineering with its excellent performance, which has brought remarkable economic benefits, and its market prospect and development potential are inestimable. Up to now, the construction methods of domestic FRP pipeline are all referring to other materials, and there is no research on the construction method of super large FRP pipeline. Based on this status quo, In this paper, the construction technology of super large glass fiber reinforced plastic pipeline is studied in connection with the second phase of the whole project of seawater cooling water intake in Jubail Industrial Zone, Saudi Arabia. Hope to provide reference and guidance for the construction of other super-large FRP water pipeline projects. The main research contents of this paper are as follows: (1) through theoretical analysis and calculation, the main contents of this paper are as follows: (1) from four aspects of pipeline installation construction, work pipe through road casing construction, anti-drift pipe construction, valve well embedded casing construction, Put forward the construction plan of super large FRP water pipeline, (2) carry on the test to the proposed construction plan, including the field test and the typical construction section test, then verify the feasibility of the construction plan; (3) through the analysis of the problems existing in the test, The construction scheme is improved accordingly. (4) combined with this project, the construction technology of super large FRP water conveyance pipeline is summarized. The main conclusions of this paper are as follows: (1) the pipe diameter of super large FRP pipeline is large, so it is necessary to consider hoisting and transportation in the construction of pipeline installation. Deformation and the accuracy of docking, etc. (2) the length of super large FRP pipeline is longer and the weight of the pipe is larger, so special attention should be paid to the deformation and displacement of the pipe when carrying out the construction of the working pipe through the road casing; (3) the buoyancy of the super large FRP pipeline is larger, The traditional sand bag method can not be used in the construction of anti-drift pipe, so it is necessary to do a good job of dewatering measures in construction. (4) in the construction of the valve well of super large FRP pipeline, special attention should be paid to the accuracy of the docking position of the flange short pipe. The research results of this paper have been successfully applied to practical projects and have a good reference and guidance function for the construction of other super large FRP pipeline projects.
