大型输水渠道改扩建关键技术及设备的研发与应用

Research and application of key technology and equipment for reconstruction and expansion of large water transfer canal projects

  • 摘要: 北疆长距离输水渠道改扩建工程,事关北疆地区的供水效益和工程安全。针对北疆供水工程渠道改扩建施工存在的渠基膨胀土、新老防渗膜连接、排水软管易变形、人工劳动力短缺等工程问题,研发了多功能混凝土制缝机、表面成型机等渠道一体化施工设备,极大提升了工程施工效率、确保了工程质量。通过室内试验和现场示范开发了KS热熔胶粘接和套管内旋固膜技术,保障了新老防渗膜的高效连接。研发了深埋地下软管的变形复位装置,通过该装置可以无创伤地将渠基排水体的淤堵进行快速疏通,避免了大开挖,为渠道的长期安全运行提供了支撑。本系列设备和技术在北疆供水工程中得到示范应用,对类似大型渠道工程的改扩建具有参考指导价值。

     

    Abstract: The reconstruction and extension project of the long-distance water transfer canal in Northern Xinjiang is key to water delivery efficiency and project safety. In order to solve the existing problems of expansive soil, the new and old anti-seepage geomembrane connection, easy deformation of drainage pipes, and labor force shortage, the multi-functional gapping machine, concrete surface molding machine and other integrated machines were developed, construction efficiency and project safety were enhanced, and the demanded labors were sharply reduced. The KS hot melt adhesive bonding and inner tube spinning geomembrane technology were developed by laboratory test and field demonstration, which ensured the efficient connection of new and old impermeable geomembranes. The deformation resetting device of deeply buried underground hose was developed, through which the blockage of the water body in the foundation of the canal could be unclogged quickly, thus avoiding large excavation and providing support for the long-term safe operation of the channel. A series of equipment and technologies have been demonstrated and applied in the north Xinjiang water supply project, and produced great social and economic benefits. The research results have important reference values to the reconstruction and expansion of similar channel projects.
