Abstract

The invention discloses a fast leaking stoppage device and leaking stoppage method for a strongly-permeable and loose stratum. The device comprises a drilling tool for drilling a grouting hole, a combined floral pipe and a sealing and stopping body for sealing the opening of the grouting hole after the combined floral pipe is inserted in the grouting hole; the combined floral pipe comprises at least one grouting pipe group, each grouting pipe group comprises two grouting pipes, the opening of the lower end of each grouting pipe is sealed, the upper end of each grouting pipe extends out of the opening of the grouting hole, the end face or the peripheral face of the lower end of each grouting pipe is provided with a grouting floral hole, and the heights of the lower end faces of all the grouting pipes in the combined floral pipe are all different. The method comprises the steps that the grouting hole is drilled and the combined floral pipe is inserted in the grouting hole; quick-solidification cement mortar is adopted to pour the opening of the grouting hole; each grouting pipe is filled with stabilized cement-clay slurry; one grouting pipe in each grouting pipe group is grouted with cermet slurry and the other grouting pipe is grouted with water glass slurry, so that the two kinds of slurry are mixed to fill the gap in the strongly-permeable and loose stratum and fast seal and stop a leakage stoppage channel.

Description

technical field [0001] The invention relates to the technical field of grouting construction, in particular to a fast leak-stopping device and a leak-stopping method for strong water-permeable loose formations. Background technique [0002] In engineering construction, highly permeable loose strata mainly refer to soil layers with high permeability coefficients such as earth-rock accumulations, original sand and pebble overlays, earth-rock filling layers, etc. Relatively waterproof. For the seepage of strong permeable and loose strata, it is more effective and simple to adopt double-liquid grouting technology to prevent seepage and plugging. The existing relatively advanced technologies mainly include sleeve valve pipe double-liquid grouting technology and buried pipe lifting rod pure pressure double-liquid Grouting technology, the common feature of these two double-liquid grouting technologies is that a single grouting pipe is used in the hole, and the cement grout and wat...
