Embodiment Construction

[0019] The structure of total station prism group of the present invention is as figure 1 As shown, it includes a total station base 101, base screws 102, a total station base plate 103, an operation panel 104, a total station support 105, a telescope 106, a handle 107, a handle disassembly button 108, and a prism 109. Wherein, total station base 101, base screw 102, total station bottom plate 103 have constituted total station base, are used for fixing total station and leveling total station; Operation panel 104 is used for total station Operate; the total station bracket 105 is used to fix the telescope 106 and the handle 107, and it is disassembled by the handle disassembly button 108; the prism 109 is fixed at the center of the handle 107. The total station support 105 can rotate 360 ​​degrees with its vertical center as a fixed axis, and simultaneously drive the operation panel 104, the telescope 106, the handle 107 and the prism 109 to rotate together.

Abstract

The invention discloses a total station prism group, a tube push bench guide system for tunnel construction and a guide method of the tube push bench guide system. The tube push bench guide system for tunnel construction comprises a laser target, a main total station prism group, a plurality of branch total station prism groups, a rear prism, a communication box and a computer. The laser target is arranged on a tube push bench in a tunnel, the main total station prism group is arranged on a mounting support in a tunnel starting well opening, the rest branch total station prism groups are arranged on tunnel segments which are arranged between the laser target and the main total station prism group and advance along with the rube push bench one by one at intervals along with the tunneling of the tube push bench. The rear prism is arranged on the wall of the tunnel starting well opening, and the main total station prism group and the branch total station prism groups are all connected with the computer. The system and the method can achieve automatic measuring of gesture of the tube push bench during long-distance curved tube pushing tunnels and guide tunneling construction of the tube push bench.

Description

technical field [0001] The invention belongs to a tunnel surveying device and method, in particular to a total station prism group, a pipe jacking machine guiding system for tunnel construction and a guiding method thereof. Background technique [0002] In tunnel surveying, a total station is usually used for surveying work. The total station is an instrument that can simultaneously measure angles (horizontal angle, vertical angle) and distance measurements (slope distance, horizontal distance, height difference). However, in the pipe-jacking tunnel, since the segments are always in motion, the total station itself is unstable and cannot perform measurement work like a shield tunnel. For short-distance straight pipe-jacking tunnels, a total station is usually installed at the originating wellhead, and a laser target is installed on the pipe-jacking machine to measure directly without changing stations. Taking measurements, often by hand, is inefficient. Contents of the in...
