Composite geomembrane expansion and contraction amount reserving tool and construction method thereof
The invention provides a composite geomembrane expansion and contraction amount reserving tool and a construction method thereof.The tool comprises a track frame and a grabbing expansion and contraction device arranged on the track frame in a penetrating mode, the track frame is of an arch-shaped structure, and the arch-shaped part is arranged above the expansion and contraction amount reserving part of a composite geomembrane; the grabbing telescopic device penetrates through the arch structure and extends to the telescopic amount reserved part of the composite geomembrane, and the telescopic amount reserved part of the composite geomembrane is grabbed to form a preset arch. By means of the method, the problems that the later welding difficulty is large, the welding quality cannot be guaranteed and the like due to the fact that the telescopic allowance of an existing composite geomembrane is not accurately controlled can be solved.
本发明提供一种复合土工膜伸缩量预留工具及其施工方法，其中的工具包括轨道框架、贯穿设置在所述轨道框架上的抓取伸缩装置，所述轨道框架为拱形结构，所述拱形部位设置在复合土工膜的伸缩量预留部位的上方，所述抓取伸缩装置贯穿设所述拱形结构，并延伸至复合土工膜的伸缩量预留部位，对所述复合土工膜的伸缩量预留部位抓取形成预设拱形。利用本发明，能够解决目前复合土工膜的伸缩预留量控制不精确而导致后期的焊接难度大、焊接质量得不到保证等问题。
