Abstract

The invention relates to a method for punching a transverse blind hole. The blind hole is punched through a punching mechanism. The punching mechanism comprises an annular blade seat, a cast iron outer sleeve arranged at the tail end of the annular blade seat in a sleeve mode and a drill rod which penetrates in the cast iron outer sleeve, is connected with the tail end of the blade seat and is ofa pipe body structure. The outer peripheral surface of the tail end of the annular blade seat is provided with a protective ring, the front end of the cast iron outer sleeve is provided with an end ring capable of being in butt joint with the protective ring, the projection of the inner peripheral surface of the end ring in the axial direction of the drill rod is all located on the protective ring, the inner end of the end ring is provided with an induction switch matched with the protective ring and connected in series with a warning lamp located at the rear end of the cast iron outer sleevethrough a wire, and the front end surface of the annular blade seat is provided with a plurality of blades capable of being folded together and penetrating through the end ring. The method for punching the transverse blind hole has the advantage of good safety, and solves the problem of poor safety in the existing blind hole construction process.

Description

[0001] This application is a divisional application of the application number 2019102737462, the application date is April 07, 2019, and the name is "horizontal blind hole punching square". technical field [0002] The invention relates to the technical field of infrastructure construction, in particular to a method for drilling a transverse blind hole. Background technique [0003] In daily production and life, it is often encountered that a horizontal blind hole needs to be formed on a stone mountain (that is, a stone mountain). It is discharged to form a blind hole blank, and a concrete layer is poured on the hole wall of the blind hole blank to prevent the stones on the hole wall from falling during use. The existing construction method has the following disadvantages: during the construction process in the blind hole blank, it is easy to produce safety accidents in which stones fall and damage people and objects, that is, the safety during construction is poor. Conten...
