Problems solved by technology

[0003] However, this measurement method requires surveyors to go downhole with special measuring instruments on their backs for actual measurement, and the on-site measurement procedures are cumbersome, which takes up a lot of head-on construction time. For the construction site, it is urgent to use the roof and floor elevations that the construction thinks of to carry out layer control or The technicians of the construction unit install the laser according to a group of centerline points measured and set up to meet the current production needs, but it happens that the surveyors do not have time to go to the site for actual measurement. Laser data and roof and floor elevation data are imperative

Embodiment 1

[0033] Embodiment 1 The method of measuring in the alley

[0034] First, let me introduce how to use a tape measure and a transparent plastic hose to obtain laser data in a horizontal roadway. The horizontal roadway mentioned in the underground is not a horizontal roadway in the absolute sense. They generally have a certain construction slope, but the slope is relatively small, generally 0.3%. Let's take a horizontal roadway with a 0.3% uphill slope as an example to introduce how to use a transparent plastic hose and a tape measure to obtain a set of laser data of the center line and the roof elevation of some center line points.

[0035] In the group of midline points we usually mark, there is generally one point that is a traverse point, and the surveyors of this point have provided accurate coordinates and elevations, while the other 2 or 3 are midline points, and these points are just in line with the The wire point is on a straight line, which provides a certain construc...

Embodiment 2

[0037] Embodiment 2 Inclined lane test method

[0038] The above is the method of using transparent plastic hose and tape measure to obtain accurate laser data and related point elevations in the roadway. Because it is carried out in the alley, it is relatively convenient to measure and adjust, and I think it is relatively simple. Now let me introduce how to obtain the number of lasers and measure the elevation of relevant points in the inclined lane. The principle of point measurement in inclined alleys is similar to that in horizontal alleys, but the data adjustment range is relatively large, which is somewhat difficult to control. now with figure 2 Take an example to introduce how to use transparent plastic hose and tape measure to obtain construction laser data and related point elevations.

[0039] like figure 2As shown, it is a set of midline points provided by surveyors, D1 is the traverse point, the elevation is H1, and Zhong1, Zhong2 and Zhong3 are the provided ...

Embodiment 3

[0041] The following is a detailed explanation through an inclined lane measurement case

[0042] 1. Roadway layout and center line extension survey

[0043] The following is an example of a group of median lines measured by 14148 Yunshun. The roadway is a 12° inclined roadway with a design height of 3.6m and a design width of 5.2m. The part of the inclined roadway has been constructed for 37m. , "B7" is the wire point, "Zhong 1" and "Zhong 2" are the center line points, the elevation of B7 point is -496.598, and the roadway plan is as follows image 3 shown.

[0044] Because the slope of the roadway is 12°, the slope is relatively large. For the convenience of measurement, a transition point "plus" point is temporarily added between B7 and middle 1 point. The roadway profile is as follows Figure 4 shown.

[0045] 2. Measurement steps of midline point elevation and measurement method of laser data

[0046] First, mark a1 on the suspension line of wire point "B7" with gun ...

Abstract

The invention provides a method for emergency measurement and setting of laser data and elevation of transmission points. First, vertically hang wires at the wire point and all midline points, install a laser instrument below the wire point, and adjust the laser beam to be consistent with the slope of the roadway floor; Mark a1 on the vertical line, measure b1, c1, ... on the same horizontal plane as a1 on the vertical line of other midline points; respectively make marks b2, c2, ... after slope correction on the vertical line; Mark a2 at the intersection of the vertical line and the laser beam, then measure the distance from a1 to a2, mark b2, c2, ... upwards with the same distance from a1 to a2 as b3, c3, ...; measure a2, b3, c3 , ... point to the corresponding guide point and each centerline point respectively, calculate the distance from the laser to a1 and the elevation of the laser mark on the centerline point. The advantage is that there is no need for surveyors to carry special measuring instruments to go downhole for actual measurement, which not only reduces the cumbersome measurement procedures for surveyors, but also reduces the time spent on head-on construction to a greater extent.

Description

technical field [0001] The invention relates to the technical field of surveying, in particular to a method for emergency surveying and setting of laser data and elevation of transmission points. Background technique [0002] When measuring laser data and point elevations underground, surveyors generally use special measuring instruments, such as theodolites, levels, total stations, and other instruments, to measure along certain wires or leveling routes. After going into the well, the surveyors will perform internal calculations and add the corresponding tension correction, vertical correction, meteorological correction, spherical correction and other correction data to obtain more accurate measurement data. Then, according to the calculation results and the corresponding design drawings, a construction contact letter is issued to the construction unit and relevant functional departments, so that relevant personnel can carry out construction or supervision according to the ...
