Embodiment Construction

[0021] Utilizing the underground pipeline fast measuring instrument and measurement technology method to measure the underground pipeline has made great improvements and innovations in theoretical thinking and practical application. The specific measurement method is:

[0022] 1) For underground pipelines that cannot be reached artificially, use such as figure 2 The single well orientation method shown; first open the surface manhole cover of the underground pipeline, then place figure 1 The instrumentation shown is placed above the manhole cover;

[0023] 2) Turn on the instrument, and use two GPS antenna heads to obtain the actual coordinates of the two ends of the straight rod (X 1 , Y 1 ,Z 1 ), (X 2 , Y 2 ,Z 2 ), then, using the mathematical model① Obtain the coordinates of the instrument center of the MINI super station instrument, where (x, y, z) is the coordinate of the instrument center, (ΔX, ΔY, ΔZ) is the center displacement deviation of the instrument calib...

Abstract

The invention discloses a rapid underground pipeline element measuring instrument and a technical method. Distance and angle measuring functions of an MIMI smart station and a positioning function of a GPS antenna head are integrated, and accurate positioning of a point to be measured is achieved. Underground pipeline elements are determined by respectively utilizing single-well directional and non-directional traverse survey and branch traverse survey methods according to the three situations that a pipeline can be reached artificially, the pipeline cannot be reached artificially and an underground pipeline multi-way joint cannot be reached artificially, and determination of the underground pipeline elements, pipeline routing and the like are achieved.

Description

1. Technical field [0001] The invention relates to a measurement technology for underground pipelines, in particular to a quick measurement instrument and technical method for elements of underground pipelines. 2. Technical background [0002] Underground pipeline measurement work includes construction measurement (planning and setting out) of new underground pipelines, completion measurement of newly buried pipelines, and detection and measurement of existing pipelines. Underground pipelines are mainly divided into power pipelines, telecommunications pipelines, water supply pipelines, gas pipelines, sewage Different types of pipelines, industrial pipelines, etc., and different underground pipelines have different measurement methods due to factors such as burial depth and pipeline direction. So far, traditional underground pipeline measurement methods are mainly divided into two types: pipelines that can be reached artificially and pipelines that cannot be reached artificia...
