Reservoir area anti-seepage geomembrane overhauling device
The invention provides a reservoir area anti-seepage geomembrane overhauling device, and belongs to the technical field of hydraulic engineering, and the reservoir area anti-seepage geomembrane overhauling device comprises a base membrane adsorption assembly and a covering membrane delivery assembly. The vacuum box is communicated with an external vacuum pipeline to adsorb the geomembrane, at the moment, the lifting cylinder lifts the geomembrane on the two sides of the crack, in the lifting process, the bottom of the geomembrane is separated from the supporting layer, wrinkles of the original geomembrane are absorbed till the geomembrane area needing to be repaired is flat, contact between the geomembrane welding area and residual seepage water of the supporting layer is reduced, and the repairing efficiency is improved. And the supporting layer does not need to be aired for a long time, and the reservoir area geomembrane repairing period is shortened. Certain high temperature can be generated in the geomembrane welding process, residual water vapor between the geomembrane and the supporting layer is evaporated and condensed on the geomembrane, a geomembrane repairing area is lifted through vacuum adsorption, condensed water drops can be reduced to flow to a crack and flow to a welding area, the water explosion sputtering phenomenon in the geomembrane welding process is reduced, and the quality of welding seam repairing is improved.
本申请提供了水库区防渗土工膜检修装置，属于水利工程技术领域，该水库区防渗土工膜检修装置包括基膜吸附组件和覆膜递送组件。真空箱连通外部真空管路对土工膜进行吸附，此时提缸提起裂口两侧土工膜，提起的过程中土工膜底部与支持层脱离，并吸收原先土工膜的褶皱，直到需要修补的土工膜区域平整，减少了土工膜焊接区域与支持层残余渗水的接触，无需长时间对支撑层进行晾晒，减少库区土工膜修复工期。土工膜焊接过程会产生一定的高温，土工膜和支持层之间的残余水汽蒸发会凝结在土工膜上，真空吸附抬高修补土工膜区域，可减少凝结水滴流向裂口顺流到焊接区域，减少焊接土工膜过程中水爆溅射现象，提高修补焊缝的质量。
