Abstract
The invention discloses an orifice rapid hole sealing device and method for an underground large-dip-angle pressure measuring drill hole with the diameter of 75 mm, and belongs to the technical field of cement mortar hole sealing. The orifice rapid hole sealing device comprises a rapid hole sealing assembly which is formed in the underground pressure measuring drill hole and installed on the inner side of the pressure measuring drill hole; the rapid hole sealing assembly comprises a grouting pipe and a pressure measuring pipe which are arranged side by side, a pipe hoop assembly is arranged between the outer side wall of the grouting pipe and the outer side wall of the pressure measuring pipe in a sleeved mode, the pipe hoop assembly comprises two symmetrically-arranged clamping plates, a hinge is installed between one sides of the two clamping plates, and corresponding screw holes are formed in the middles of the two clamping plates. Fixing bolts are connected into the corresponding screw holes in a screwed mode, and nuts are connected to the tail portions of the fixing bolts in a screwed mode for reinforcement. According to the quick hole sealing device and method for the hole opening of the underground large-dip-angle 75mm-diameter pressure measuring drill hole, the device is simple, easy to machine and convenient to install, the hole sealing quality is improved, and the labor intensity of workers is relieved; the method is simple, convenient and reliable, and the hole sealing efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of cement mortar hole sealing, in particular to an orifice fast sealing device for underground pressure measuring drilling with a large inclination angle of 75 mm in diameter, and also relates to a rapid orifice sealing device for underground pressure measuring drilling with a large inclination angle of 75 mm in diameter. A hole sealing method of a hole sealing device. Background technique [0002] In recent years, with the continuous extension of mines, the number of kilometer-deep wells, high gas and coal and gas outburst mines is increasing, the original gas content and pressure of coal seams are increasing, and the amount of coal seam gas emission is also increasing. The problem of coal and gas outburst is relatively prominent, which brings great challenges to the management of underground gas disasters and the guarantee of safe production in coal mines. In order to do a good job in the prevention and c...
