Embodiment Construction

[0018] Such as Figure 1-7 , a fast lofting and positioning device for drilling and blasting cloth holes in tunnels, which includes a turntable 8, a hollow double-ended screw 9 is vertically arranged in the middle of the turntable, grooved nuts 10 are arranged at intervals on the hollow double-ended screw, and grooved nuts are arranged in grooves. Arc-shaped support plate 11, inserting rod 15 is inserted inside the hollow double-ended screw rod, and the outer end of the inserting rod is vertically provided with a gravity indexing plate 7 and a scale slide frame 6, and a scale rod 5 is arranged in the scale slide frame. There is a gap between the insertion rod and the hollow double-ended screw rod, and the two can rotate mutually. The lofting positioning device also includes a dotting long rod 3, and a laser pointer 4 is arranged on the top of the dotting long rod. The arc brace is made of two sections that can be folded, and the center is connected by a pivot pin 12 .

Abstract

The invention relates to a device and a method for performing tunnel drilling and blasting hole arrangement and rapid lofting and positioning. The device comprises a turnplate. The middle part of the turnplate is vertically provided with a hollow double-thread screw; groove nuts are arranged on the hollow double-thread screw at intervals; arc-shaped supporting plates are respectively arranged in grooves of the groove nuts; an inserted link is inserted into the hollow double-thread screw; the outer end part of the inserted link is vertically provided with a gravity index plate and a staff carriage; a staff pole is arranged in the staff carriage; the inserted link and the hollow double-thread screw are arranged at intervals, and mutually rotate. The lofting and positioning device also comprises a dotting pole; the top end of the dotting pole is provided with a laser pen. The device and the method disclosed by the invention have the beneficial effects that the process of the tunnel drilling and blasting hole arrangement is simplified, the hole arrangement time is shortened, and the operation is simple, safe and reliable. Compared with hole arrangement performed by using a measuring apparatus conventionally, the hole arrangement performed by using the device and the method disclosed by the invention has great technical economic advantages, and the progress of tunnel drilling and blasting excavation construction can be greatly accelerated.

Description

technical field [0001] The invention relates to a stakeout device and a rapid stakeout positioning method, and is a tunnel drilling and blasting precise and rapid positioning hole layout device and method which can replace measurement stakeout. Background technique [0002] Before the excavation of tunnel drilling and blasting, in order to ensure that the drilling and blasting section size of the tunnel meets the design requirements, and the tunnel is not deviated and deflected, it is necessary to accurately calculate the charge amount of the tunnel drilling and blasting, and carry out accurate drilling. Measure hole. Whether it is a circular tunnel, a city gate tunnel or a horseshoe-shaped cross-section tunnel, the centering hole is measured, and then under the guidance of the measuring instrument, the drilled holes are marked on the excavation section manually with paint, etc., for Drilling rigs are used for positioning. Although this method is accurate, it is very time-c...
