Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to various surveying methods, such as in tunnel tunnels, which are performed to construct a tunnel with high accuracy and high quality, mainly in mountain tunnel construction, and a program for displaying the surveying results.
[0002]
[Prior art]
For example, in mountain tunnel construction represented by the NATM method, various types of surveying are performed to construct a tunnel with high accuracy and high quality. As the surveying items, for example, the top, left, and right points of the shoring are surveyed to check the installation accuracy, the shoring inspection to check the installation accuracy, the atari surveying to detect the hit at any cross section or any point after excavation, the underground Initial value measurement of A measurement (crest subsidence / inside sky displacement), A measurement such as prism setting measurement, cross section measurement to measure inside cross section of excavation of arbitrary cross section, required depth and invert of arbitrary point in invert excavation There are an inverted survey for displaying the finished height, an arbitrary point survey for measuring an arbitrary point using a prism or a non-prism, and a reinforcing bar survey for measuring a reinforcing bar position.
[0003]
In such various surveys, the survey is performed based on the three-dimensional coordinates. For example, in JP-A-2001-182484 and JP-A-3-103595, if a surveying instrument such as a total station capable of measuring a distance and an angle is installed at a predetermined position, the coordinates of the installation are determined. Is measured by another surveying instrument, and after setting the installation coordinates to be known, a reference point whose coordinates are known in advance is backsighted, angle measurement and distance measurement are performed, and then the coordinates to be measured are collimated. The three-dimensional coordinates of the collimation point are calculated based on the angle and distance measurement data.
[0004]
On the other hand, in the surveying of the light part outside the tunnel, two people survey the linear center in the horizontal alignment of the target structure such as road alignment and track alignment, install the surveying machine again at the surveyed center, and from there Collimate the reference point or other center point, swing the angle at right angles to the design alignment, and change the structure shape specified in the design cross section (cross-section at right angles to the design alignment). Determine or measure the desired location on the design cross section, calculate the coordinates obtained from the horizontal distance or ranging angle, and move a predetermined distance from the linear center on the previously calculated design cross section The deviation from the coordinates of the position is repeatedly checked or obtained by converting the measured horizontal distance or ranging angle with the linear center as an axis.

[Problems to be solved by the invention]
However, in the case of the conventional surveying method, there are various problems in the surveying work because the installation coordinates of the surveying instrument are basically considered as fixed points and the position is known by surveying. For example, even if the surveying platform moves due to blasting vibration or displacement of the ground, the surveying is continued without being noticed.As a result, there is an error in the surveying, the tunnel position shifts, a big hit or extra digging occurs. In some cases, a problem such as the occurrence of a problem occurs. In addition, every time the surveying equipment is changed or moved, another lightwave surveying instrument is required to measure the installation coordinates, and a plurality of measurements are required for the instrument coordinate measurement work (instrument installation to reference point collimation). It required staff and took a long time to set up.
[0007]
In addition, in the invert survey individually, at the preparation stage before construction, two or more persons survey the tunnel linear distance, the distance from the center, the height from the tunnel reference point, etc. by underground survey from the reference point, and excavation A laser must be installed so that the position information on the floor can be recognized, or a nail must be nailed to the side wall, etc., and a thread must be stretched. The height from the floor with the excavation floor must be calculated for each position away from the center. I had to. On the other hand, in the shoring inspection and reinforcing bar surveying, even if the coordinates of the shoring position and the reinforcing bar position can be measured, there is no information such as which position is relative to the tunnel section. Therefore, there was a problem that the distance from the center point of the tunnel section had to be additionally measured separately. In this case, when the tunnel shape is a complex cross section of a plurality of arcs, the surveying itself for finding the tunnel center point takes a lot of trouble and time. If the tunnel has a certain slope or a vertical curve, it is necessary to construct the lining concrete, which is the final structure, in a direction perpendicular to the certain slope and the vertical curve. . However, in conventional surveying, surveying on a vertical surface is fundamental, so in order to grasp the exact position, a special three-dimensional calculation is performed, or the measuring point obtained by leveling is slid by a certain dimension. It was necessary to calculate it, and it contained a considerable error.
[0008]
On the other hand, surveying a light part such as a slope, for example, outside the tunnel, requires two processes, center surveying and cross-sectional surveying. Therefore, there are problems in that surveying takes time and errors are accumulated. Was. In addition, when performing surveying in one process for labor saving, it is necessary to calculate the three-dimensional coordinates of a certain measuring point each time using a calculator or the like, which takes time and may cause an erroneous calculation. There was such a problem.
[0009]
Therefore, a main object of the present invention is to achieve simplification, labor saving, and high precision of various underground surveys or surveys at a light portion performed during tunnel construction, thereby improving the efficiency of construction.
[0010]

When the "guidance" button 18 is selected, the screen is switched to the guidance screen 26 shown in FIG. The screen is divided into an upper setting and a lower setting. When the upper setting specifies a cycle number or a tunnel linear distance TD, and specifies up / left / right, the collimating direction is guided in that direction. I have. The lower setting is for manual guidance in the left, right, up and down directions. The inner “>” button is the fine movement button 20 and the outer “>>” is the coarse movement button 21. Note that the collimating direction can be visually confirmed by a laser emitted from the total station 5.

In the inspection of the steel support, the total station 5 performs surveying using at least three inspection points, that is, the left end inspection point, the top end inspection point, and the right end inspection point of the steel support. At this time, it is basically desirable to perform the measurement by installing a prism at each of the inspection points.However, at the top end inspection point, when it is difficult to secure a scaffold and to install the prism, It is possible. In that case, non-prism measurement may be used.

Regarding the rebar separation, by selecting the “Result display” button 25, the measurement results that have been measured are displayed at the same time.
[0043]
As described above, the present invention has been described in detail.In recent years, surveying instruments having a monitor screen and those having a computer function have been proposed, so that the surveying instrument does not have the handy terminal separately, Some or all of the handy terminal functions may be provided.
[0044]
In the above-described embodiment, the tunnel survey has been described in detail. However, the present invention can be applied to survey of a light portion such as slope measurement outside the tunnel in the same manner. When the method is applied to the surveying of the lighting part, the center surveying is not required, and the surveying can be performed in one process and by one person, so that the time can be reduced and the error can be minimized. In addition to the cross section clearly shown in the drawing, it is possible to immediately carry out surveying on the spot while checking the place where the stake is to be applied according to the local topography. By inputting a design finish line (which may be a cut or an embankment) in advance, the distance between the X, Y, and Z components of the measurement point on the specified cross section is displayed. Therefore, it is possible to determine on the spot which direction should be moved and how much, and to execute the survey again, so that highly accurate and efficient survey can be performed.
[0045]
Furthermore, by utilizing the fact that the current position is displayed in the X, Y, and Z component directions with respect to the previously input design finish line, it is possible to grasp the performance with respect to the design dimensions of the light construction, By being able to grasp whether progress has been made to a certain degree, it is possible to omit the calculation of quantities by drawing the results of conventional surveys, and to achieve a significant increase in efficiency. That is, conventionally, in order to calculate the cutting work volume of the cut and embankment in the surveying of the light part, each work volume cross-sectional shape is measured, each cross-sectional view is described, each cross-sectional area is calculated, and the average cross-sectional method is calculated. Although it was common to calculate the volume of soil produced in this way, this method required cumbersome surveying and took a lot of trouble such as drawing a cross-sectional view. In the case of the present invention, all information on the planned finish line is stored in the computer, and the deviation from the survey target point to the predetermined point is grasped. By using this method, you can easily draw the lines of the actual finished section for the preset plan section shape, calculate the area with the original ground line, and calculate each measured section distance by the average section method. Thereby, it is possible to calculate the amount of construction work. As a result, the calculation of the cross-sectional view, which was conventionally required, can be automatically drawn, and the amount of work that can be performed can be grasped by designating a certain section without performing a special calculation.
[0046]
