摘要：【中文】本发明公开了一种地下工程施工中，围护结构部分失效或坑底发生承压水突涌时，借助土体、砂石、混凝土等材料，通过在透水点位置先安装带阀门的硬质引流管，并在上方堆压少量土体，最后在土面浇筑薄层早强混凝土等，待混凝土初凝后，关闭引流管阀门，快速形成一大水力坡降比的薄壁结构，完成抢险。过程中，加强积水抽排，保证透水事故区域堆高面不被水淹。该方法具有速度快，2～3小时即可完成抢险，对环境影响小、所需人员少、材料易得、操作简便、成本低、后期清障简单等，适用于各种基坑开挖围护结构部分失效、坑底发生承压水突涌、隧道联络通道透水等事故的应急抢险。 【EN】The invention discloses a method for rapidly forming a thin-wall structure with a large hydraulic gradient ratio in underground engineering construction by installing a hard drainage tube with a valve at a water permeable point, piling and pressing a small amount of soil above the hard drainage tube, and finally pouring thin-layer early-strength concrete and the like on the soil surface by means of materials such as soil, sand, concrete and the like when a building envelope is partially failed or confined water suddenly gushes at the bottom of a pit, and closing the valve of the drainage tube after the concrete is initially set, thereby rapidly forming the thin-wall structure with the large hydraulic gradient ratio to finish emergency rescue. In the process, accumulated water pumping and drainage are enhanced, and the water-permeable accident area pile height surface is prevented from being flooded by water. The method has the advantages of high speed, capability of completing emergency rescue within 2-3 hours, small environmental influence, less required personnel, easily available materials, simplicity and convenience in operation, low cost, simplicity in later-stage obstacle removal and the like, and is suitable for emergency rescue of accidents such as partial failure of the enclosure structure for excavation of various foundation pits, sudden surge of confined water at the pit bottom, water permeation of a tunnel communication channel and the like.
