Abstract

<P>PROBLEM TO BE SOLVED: To provide a drawing method of a survey result when an engineer performs a field work in the field. <P>SOLUTION: In a longitudinal/cross-sectional survey, description on a level book (field notebook) is performed. As a desk work, map drawing is started. In order to acquire a drawing from the field notebook of the field work, first of all, a ground height of a reference point is to be known. The spot is required for starting survey, and when seeing-through by a level in the first place, the spot is used for erecting a staff (box scale) thereon and reading a gage rod on the staff for a start. This operation is called as backsight (BS), and an instrument height is calculated at that time. When the instrument height is known, it is illustrated and decided on a longitudinal section view or on a cross-sectional view as one height standard, and then a figure of foresight of the survey result is read from the field notebook based on the reference line, and downward plotting is performed by a scale from the reference line, to thereby determine the ground height of the spot. A longitudinal/cross-sectional view can be acquired by connecting each point on the determined spot. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

発明の詳細な説明Detailed Description of the Invention

外業における野帳の製作は、水準儀を据え付けて、始点の地盤高のわかっている所にスタフを立て、その読みをとり、(後視)を、のちに、次の地点の所へスタフを立て読みをとる(前視)そして読みを野帳え記入する。また測量の範囲が水準儀の読み取りに限界を越えた場合器械を据え治すのであるが据え治す所で

Figure 2010066249
を読み、後に、スタフを次地点の所へ立てスタフの読みをとり前視とし、測量作業を順次進めていく。やがて外業が終ると、内業にかかるのであるが、図面作成の段階で、野帳の計算において、測点の地盤高が解って居れば、それに後視を加えて、器械高として、これを基としてこの器械高を、図面上に、線を引き、測点2 3、4、5を図上にプロットして各測点の高さが決まれば、後は測点の標高をつなげて行けば、図面は作成される。又、器械高の線から、前視を、スケールで下方へ図示すれば、求める測点地盤高は求められる。この様な、図面の作成は、計算を省き、かつ正確なる地盤高が製図できる。In the field work in the outside business, the standard is installed, the staff is set up at a place where the ground height of the starting point is known, the reading is taken, (back-viewing), and then the staff is moved to the next place. Take a reading (foresight) and fill in the field. In addition, when the range of surveying exceeds the limit of level reading, the instrument is fixed.
Figure 2010066249
Afterwards, the stuff is placed at the next point and the stuff is read as a foresight, and the surveying work proceeds in sequence. Eventually, when the outside business is over, it will take on the internal business, but at the stage of drawing creation, if the ground height of the station is known in the calculation of the field book, add the backsight to it and add this as the instrument height. Based on this, draw the line on the drawing, plot the measurement points 2, 3, 4 and 5 on the drawing to determine the height of each measurement point, then connect the elevations of the measurement points. If you go, the drawing will be created. Moreover, if the foresight is illustrated downward on a scale from the line of the instrument height, the required ground height can be obtained. The creation of such a drawing eliminates the calculation and can produce an accurate ground height.

測量学に於ける水準測量は縱断測量と横断測量とに分れ、外業と内業としがある。外業である野外測量は、実測値を野帳に記入する。
内業は、記入された地盤高を図面化するのであるが、新しい方法は図化するのに、野帳を計算をはぶき、かつ正確なる地盤高を得て製図を仕上げるものである。
Leveling in surveying is divided into diagnostic surveying and cross-sectional surveying. For field surveying, which is an outside business, the actual values are entered in a field book.
In-house work is drawing the ground height that has been entered, but the new method is to create a map with the calculation of the field book and to obtain a precise ground height to make the drawing.
