Method for plugging tube orifice of well for person in ground pipes

[0007] The blocking method of the present invention is as follows: a blocking net is built into the manhole tube hole. The blocking net has 3 irregular horizontal buckles, as shown in the figure; the first horizontal buckle 2, the second horizontal buckle 3 and the third horizontal buckle 5, the 3 horizontal buckles are in the same plane and mutually For connection, the horizontal buckle can also be two or one, but the effect of 3 is better, and the 3 horizontal buckles are basically evenly distributed in the range of 360°. Of course, it can also be made into 4 or 5 buckles, etc. The handle ring 1 is set in a plane perpendicular to the horizontal buckle plane. When the horizontal buckle plane and the handle ring plane are not at a vertical angle, it does not affect the use, that is: the horizontal buckle plane and the handle ring plane can be inclined at an angle . The handle ring 1 is one, and the handle ring 1 is connected to the horizontal buckle and is in a different plane from t
