Water-carrying grouting plugging structure and method for large-flow leakage stratum
The invention relates to the technical field of drilling of soil layers or rocks, and discloses a water-carrying grouting plugging structure and method for a large-flow leakage stratum. The water-carrying grouting plugging structure comprises a porous resin consolidation body and a grouting consolidation body which are plugged in stratum pores near a leakage opening; and leakage objects are wrapped in the porous resin consolidation body, and the grouting consolidation body and the porous resin consolidation body are bonded into a whole. According to the water-carrying grouting plugging structure and method for the large-flow leakage stratum, the porous resin consolidation body is formed in the stratum pores through water-injection epoxy resin liquid, so that the large stratum pores are changed into small pores, the wall effect is obviously improved, the flowing resistance of fluid in the stratum pores is increased, the flowing speed of water in the stratum pores is decreased, and subsequently-injected slurry is not prone to being flushed out; meanwhile, water bodies in the stratum pores are separated, so that the subsequently-injected slurry is not rapidly diluted; and the slurry is more easily attached to the walls of the small pores in the porous resin consolidation body.
本发明涉及土层或岩石的钻进技术领域，公开了一种用于大流量渗漏地层的带水注浆封堵结构及封堵方法，包括塞堵在渗漏口附近地层孔隙中的多孔树脂固结体以及注浆固结体；多孔树脂固结体内包裹有渗漏物，注浆固结体与多孔树脂固结体相互胶结为一体。本发明中，通过注水性环氧树脂液在地层孔隙中形成多孔树脂固结体，从而将大的地层孔隙变成小孔，壁效应明显提升，增加了流体在地层孔隙中流动的阻力，减小地层孔隙水的流动速度，使后续注入的浆液不易被冲出；同时，将地层孔隙中的水体分隔开来，使后续注入的浆液不会被快速稀释；浆液也更容易附着在多孔树脂固结体中的小孔壁上。
