Embodiment

[0021] Through measurement, the flow velocity at the dew point of the main permeable channel is 0.5m / s, and the flow rate is 2.5m 3 / s;

[0022] Drill three plugging holes in the permeable channel, i.e., upstream hole 1, midstream hole 2 and downstream hole 3, with a diameter of 100 mm and a hole depth of 80 m. Add wall protection steel sleeve 4 in the interior.

[0023] Choose stones with a particle size of 15-25 mm,

[0024] In the upstream hole 1, use high-pressure wind to blow and throw the blocking stone into the hole;

[0025] In the midstream hole 2, the high-pressure wind direction is used to block the mold bag concrete, and the mold bag concrete 5 is ordinary concrete with ordinary grades packed in woven bags;

[0026] In the downstream hole 3, the betting stone is blocked with high-pressure air to form the betting stone area 6;

[0027] After the water seepage at the leakage point is significantly reduced, grout the upstream hole 1 and the middle hole 2 until the...

Abstract

The invention relates to a method for calking a deep underground nonwatertight channel, which adopts the technical proposal that the method comprises: measuring the flow velocity and the flow rate of leaked points of a main nonwatertight channel first; drilling three calking holes on the upstream, the midstream and the downstream of the nonwatertight channel, and selecting the particle diameter of calking materials to not more than one third of the aperture; using high-pressure blast to blow calking stone materials into an upstream hole; using the high-pressure blast to perform mold-bagged concrete calking on a midstream hole; using the high-pressure blast to throw the stone materials into a downstream hole for calking; and performing plaster slurry grouting on the upstream hole and the midstream hole after water seepage of the leaked points is obviously reduced until seeped water is completely calked. The method for calking the underground nonwatertight channel adopts a method for arranging the upstream hole, the midstream hole and the downstream hole and uses the stone materials, mold-bagged concrete and plaster slurry grouting to be combined with each other for calking the underground nonwatertight channel, has strong pertinence of drilling and calking, greatly improves the calking efficiency, and simultaneously reduces the calking workload and the calking cost.

Description

technical field [0001] The invention relates to the technical field of plugging treatment of underground permeable channels. technical background [0002] In the process of infrastructure construction or coal mining, it is often encountered in the excavation of underground caverns, coal seam mining or mineral exploration construction that the permeable water body is opened. In the light case, the engineering facilities are damaged, and in serious cases, the underground engineering or mine facilities are damaged. Complete scrapping or even major loss of life and property. Contents of the invention [0003] The purpose of the present invention is to provide a method that can quickly block the underground deep-buried permeable channel. [0004] The purpose of the present invention is achieved in that a method for plugging a deep underground permeable channel, [0005] Measure the flow velocity and flow rate at the dew point of the main permeable channel; [0006] Three plu...
