Embodiment Construction
[0013] The rapid plugging and drainage device of the pressure outlet hole includes a steel pipe 2 with one end extending into the borehole 1 and threaded on the outer cylindrical surface. The other end of the steel pipe 2 is provided with a control valve 3. One end of the control valve 3 is connected to a drainage pipe 4. 2 is covered with a water stop, which is composed of two metal sheets 5 and a rubber sheet 6 sandwiched between the two metal sheets 5, and both sides of the water stop are provided with nuts 7 screwed on the steel pipe. A quick-setting sealing material 8 is provided on the outside of the water-stopping parts; there are several water-stopping parts, and nuts 7 and quick-setting sealing materials 8 are arranged between two adjacent water-stopping parts; the outer edge of the metal sheet 5 Inclined inward; the method of quickly blocking and draining the pressure outlet hole, the steps are as follows: a. After horizontal drilling, it is found that pressurized wat...

The invention relates to a quick plugging and draining device and method of a pressure water outlet for tunnel engineering, solving the problems that time and labor are wasted and normal construction is influenced because the water or the cement is plugged after being jet in the traditional tunnel engineering drilling. The device comprises a steel pipe, wherein one end of the steel pipe extends to a drill hole, and the outer cylindrical surface of the steel pipe is provided with a thread, while the other end of the steel pipe is provided with a control valve; one end of the control valve is connected with a draining pipe; a water stopping piece is sleeved on the steel pipe and consists of two metal pieces and a rubber piece clamped between the two metal pieces; and two sides of the water stopping piece are respectively provided with a nut screwed on the steel pipe. The invention has the advantage of reasonable and reliable structural design and quickly and efficiently realizes the plugging to the drill hole; meanwhile, jet objects such as the water or slurry, and the like are drained to a draining system or a concrete transport cart to guarantee the safe operation of construction stuff; and the invention is suitable for the quick plugging and control of leveling advanced drilling confined water or slurry of tunnel construction.
Description
technical field [0001] The invention relates to a rapid plugging and drainage technology for a pressure outlet hole, in particular to a device and method for quickly plugging and draining a pressure outlet hole for tunnel engineering. Background technique [0002] With the increasing number of tunnel projects, tunnel water inrush and mud inrush accidents occur from time to time, and even cause serious casualties. In order to prevent water inrush and mud inrush disasters, it is necessary to drill horizontally in advance on the excavation face (face) to ascertain the geological conditions. The mud is sprayed under the pressure, which seriously affects the normal construction. The sprayed water or mud drainage must be sent to the construction drainage system in an organized way or transported to the dump site by a concrete truck. [0003] In the past, when this situation was encountered, methods such as temporarily digging trenches on the ground, stacking sandbags, etc. to int...
