Problems solved by technology

General laser surveying and mapping instruments are often prone to certain deviations due to terrain factors when setting out lines in tunnels, and manual measurement and positioning with tools such as tape measures is laborious and laborious; in addition, there are many places in the segment with reinforcement, and the brackets are drilled These positions need to be avoided during positioning. Once the positioning is not correct, the holes will be punched on the reinforcement, which will greatly affect the bearing capacity of the segment

Abstract

The invention discloses a rapid positioning device and method for a tunnel pipeline support. The rapid positioning device comprises a cross beam, supporting legs, adjusting rods, locking parts, bases, a connecting rod, a fastening part, and a positioning plate; the supporting legs are vertically arranged below the cross beam, the adjusting rods can stretch out and draw back in the supporting legs, the locking parts are used for fixing the adjusting rods on the supporting legs, and the bases are arranged on the adjusting rods; and the connecting rod is telescopically arranged in the cross beam and can be pulled out of the cross beam, the fastening part is used for fixing the connecting rod on the cross beam, the positioning plate is hinged to the connecting rod, and a positioning hole is formed in the positioning plate. The pipeline support can be rapidly and accurately positioned, and the positioning efficiency of the pipeline support is improved.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a fast positioning device and method for a tunnel pipeline support. Background technique [0002] In the field of tunnel engineering, after the tunnel segment is installed, it is necessary to install pipelines, wires, air ducts and other pipelines. For this reason, it is necessary to install tunnel supports in the arc-shaped tunnel. Before the tunnel support is installed, it is necessary to position and drill holes on the arc-shaped tunnel. The traditional positioning method is to pop out the center line of the support and hanger according to the position of the pipeline in the construction drawing, and then use a tape measure or an infrared laser surveying instrument to position the line. , and finally determine the position of the tunnel support. However, in the general tunnel pipeline installation process, since the tunnel segment is not completely horizontal when it is laid...
