Abstract

The invention discloses a tunnel drilling device capable of controlling drilling depth and a using method thereof, wherein a first baffle plate capable of adjusting position is arranged on a second plate in a control device in a direct or indirect sliding mode; the first baffle plate is positioned at one side of a second plate, away from a fixing rod; three fourth fixing holes are formed in the first baffle plate; the positions of the three fourth fixing holes correspond to those of the three third fixing holes one by one; a second baffle plate capable of adjusting position is arranged on a first plate in a direct or indirect sliding mode; the second baffle plate is positioned at one side of the first plate, away from a detection rod; the third baffle plate is provided with three second fixing holes which correspond to three first fixing holes one by one. According to the control device, the position of the first baffle plate can be accurately adjusted, so that the punching depth can be accurately controlled conveniently, the position of the second baffle plate can be conveniently adjusted, and the punching depth can be accurately controlled according to the length of the fixing rod.

Description

technical field [0001] The invention relates to the technical field of control devices, in particular to a tunnel drilling device capable of controlling the drilling depth and a use method thereof. Background technique [0002] Tunnel construction is the abbreviation of the new Austrian tunnel construction method. It is a reasonable construction method proposed by Austrian scholars from the perspective of rock mechanics in the long-term tunnel construction practice. It uses spray anchor technology, monitoring measurement, etc. And it is a new engineering construction method formed by a system composed of rock mechanics theory. During tunnel construction, flange bases need to be installed, and flange bases need to be drilled and bolted. After retrieval, the patent document with application number 201510256065.7 Disclosed is a tunnel multi-hole punching and bolting precision control device, which is composed of device I and device II. Device I is a flat plate with opening I in...
