Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tension setting device used for tensioning work at the time of ground formation and a tension setting method using the same.
[0002]
[Prior art]
Conventionally, a method shown in FIG. 1 is known as a tension setting method at the time of ground formation. Tightening work is performed, for example, when instructing the gradient or side groove position when cutting or embedding in civil engineering work, and more specifically, the position of the slope 41a and slope 41b of the slope 41, the slope As marks for instructing 1: P, 1: Q, etc. to the operator operating the heavy machinery, a stringer 40 representing these positions or numerical values is installed at each predetermined position.
[0003]
Tightening is a three-dimensional landmark. For example, in the case of a route, the position of the tension is determined based on the plane linear data, the longitudinal section data, and the transverse section data.
[0004]
When installing such a stringer 40, first, the surveying machine 42 is installed at the reference point T1 on the center line CLX of the road, and the direction perpendicular to the center line CLX from the reference point T1, that is, the arrow M− While looking at the normal direction shown in the N direction, hit the stake 43 near the shoulder 41a.
[0005]
Then, collimating the reserve pile 43 with the surveying machine 42, the distance LX1 between the placement point T2 of the reserve pile 43 and the placement point T1 on the center line CLX, and the altitude (placement) of the top end of the reserve pile 43 Height) The position of the reserve pile 43 is determined in the form of measuring ZX1.
[0006]
After that, the wooden piles 44A and 44B are placed on the line of sight connecting the placement point T2 of the reserve pile 43 and the reference point T1 on the center line CLX. Here, the wooden pile 44A is referred to as a reference pile, and the direction pile 44B is referred to as a direction pile.
[0007]
And based on the position of the reserve pile 43 calculated | required previously, by installing the cutting material 45 so that it may span over the reference | standard pile 44A and the direction pile 44B via the horizontal board 48, the cutting material 45 is made into a normal line direction. It arrange | positions toward a certain arrow M and N direction, and the punching material 45 is installed so that the inclination corresponding to the gradient 1: P, 1: Q of the slope 41 may be made using the slant rail 46 at this time. As a result, the cutting material 45 is instructed about the shape of the excavation line of the slope 41.
[0008]
Then, the length of law to be excavated with this gradient is described for each string 40. Thus, by setting the stringer 40 by the reference pile 44A, the direction pile 44B, the horizontal plate 48, the cutting material 45, etc., and installing the stringer 40 at a distance LX4 apart in the extending direction of the shoulder 41a, The excavation position of the shoulder 41a is instructed through a line of sight of a distance LX4 looking through the two stringers 40, 40 aligned in the shoulder direction.
[0009]
In order to install such a stringer 40, the operation of placing one, one reference pile 44A, the directional pile 44B, the horizontal plate 48, and the cutting material 45, and the position of the point T2 where the reserve pile 43 is placed are provided. Based on the surveying and cumbersome calculation, it is necessary to stack the work of obtaining the reference pile 44A, the direction pile 44B, the horizontal plate 48, and the cutting material 45 for each step. Is very cumbersome.
[0010]
In addition, if the reserve pile 43, the reference pile 4 4 A, and the direction pile 4 4 B are not installed in a normal line direction indicated by an arrow M-N that is exactly perpendicular to the center line CLX, the punched material The direction of 45 is bent, and the excavation line of the slope 41 where this appears is displaced, but in the tension setting method as described above, the reference point T1 on the center line CLX from the placement point T2 of the holding pile 43 Since the reference pile 44A and the direction pile 44B are driven on the line of sight by using the line of sight obtained by visual observation, the horizontal plate 48 and the cutting material 45 applied to the reference pile 44A and the direction pile 44B are normal. There is a risk of installation out of the direction.
[0011]
Therefore, in order to accurately install the stringer 40, it is necessary to patiently carry out complicated work and calculations with a skilled surveying technique, and the work labor consumed for this is very difficult (for example, patents). Reference 1).
[0012]
In such a tightening work, since the work effort is difficult, there is also a case where the position of the tightening is stored in the surveying machine 42 in advance.
[0013]
For example, as shown in FIG. 2, the intervals between the stringers are provided discretely in the longitudinal direction of the road, and in FIG. 2, symbols P <b> 1, P <b> 2,.
[0014]
The horizontal placement position (X1, Y1) of the reference pile 44A is determined in accordance with the design data, and the reference pile 44A is driven by placing the reference pile 44A at the placement position (X1, Y1). When the placement height ZX1 of the reference pile 44A is obtained by the surveying machine 42, as shown in FIG. 3, a vertical distance H1 from the apex 44C of the reference pile 44A of the reference plate 44A of the horizontal plate 48 as an attachment position with respect to the reference pile 44A. The horizontal distance H2 from the reference pile 44A of the cutting material 45 as the attachment position with respect to the horizontal plate 48 and the inclination angle θ of the cutting material 45 with respect to the horizontal direction can be obtained by calculation.
[0015]
Accordingly, the surveying machine 42 is installed at the reference point T1, the placement position of the reference pile 44A is collimated, the placement position (X1, Y1) of the reference pile 44A for each location of the cross- sectional data, and its height ZX1. Is determined, the vertical distance H1, the horizontal distance H2, and the inclination angle θ are obtained, so that the tensioning operation can be performed based on the distances H1, H2, and the angle θ.
[0016]
In addition, although the direction pile 44B may survey independently and may specify a position, when the direction pile 44B is collimated using the surveying machine 42, it is placed at a placement position hidden behind the reference pile 44A. Just do it. The distance H3 between the direction pile 44B and the reference pile 44A is, for example, 1 m and can be determined and set as a constant.
[0017]
Thus, after placing the reference pile 44A and the direction pile 44B at the predetermined placement positions, the horizontal plate 48 is driven to the attachment position at the distance H1, and then the cutting material 45 is attached to the attachment position at the distance H2 of the horizontal plate 48. The angle θ is determined by using an inclination angle measuring device (not shown), and the punching material 45 is driven against the horizontal plate 48.
[0018]
By performing such a tightening operation, the operation of striking the holding pile 43 and the like can be omitted, and the tightening operation can be performed accurately while reducing the labor of the tightening operation.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 4A shows an example of the tension setting apparatus 1 according to the present invention. The tension setting apparatus 1 includes a plurality of operation buttons as an input unit (input unit) 2 and a display unit (display unit) 3 on the front. Further, as shown in FIG. 4B, the tension setting apparatus 1 includes a control calculation unit (calculation unit) 4, a memory card 5, and a storage unit (storage unit) 6. The storage unit 6 stores design data.
The design data includes plane linear data (IP coordinates, radius, clothoid parameters), longitudinal data (elevation, gradient, longitudinal curve length), crossing data (standard cross section data), and reference pile position data. The flat linear data corresponds to a view of the completed road as viewed from directly above, and the vertical cross-sectional data is a cross-sectional view of the completed road along the extending direction of the road. The cross-sectional data corresponds to the figure seen in a cross-section along the width direction of the road after completion. This cross-sectional data is provided along the normal (MN) direction of the road as shown in FIG. The reference pile 44A is placed on the shoulder in a direction along the cross-sectional data, and its position (X1, Y1) is determined in advance.
[0031]
The memory card 5 stores a calculation program for calculating the distance H1 and the distance H2 based on each data and position information described later from the operation buttons and displaying the inclination angle θ.
[0032]
The position information is the placement position (X, Y) of the reference pile 44A and the placement height ZX of the reference pile 44A by measurement using the surveying machine 42. These position information is based on the surveying machine 42. It is transmitted to the stringer 7 using wireless means.
[0033]
As shown in FIG. 5, the stringer 7 puts the reference pile 44 </ b> A at a position that is considered to be the planned placement position (X1, Y1) of the reference pile 44 </ b> A. The surveying operator points the telescope in the direction of the planned placement position (X1, Y1), and checks whether or not the reference pile 44A is in the field of view of the telescope. If the reference pile 44A is not in the field of view of the collimating telescope of the surveying machine 42, the surveying operator instructs the stringer operator 7 so that the reference pile 44A is in the field of view of the telescope.
[0034]
The stringer operator 7 moves to the planned placement position (X1, Y1) based on the instruction and stands the reference pile 44A again. The surveyor collimates the target prism placed on the center of the reference pile 44A, and stands the reference pile 44A so that the vertical axis 44D of the reference pile 44A passes through the optical axis center (collimation axis) of the telescope. Instruct the tensioning operator 7 as much as possible. The stringer 7 moves the reference pile 44A based on the instruction, and when the vertical axis 44D of the reference pile 44A is set at a position passing through the optical axis center of the telescope and measures the distance, the angle at which the reference pile 44A stands. And the position is calculated from the distance. This is the placement position (X1, Y1) planned by design. And the top of the reference | standard pile 44A is height Z1.
[0035]
At this time, it is possible to perform the tensioning operation using the distance H1, the distance H2, and the inclination angle θ previously obtained by calculation based on the design data.
[0036]
When there is a hindrance to standing the reference pile 44A at the planned placement position (X1, Y1) and the height Z1, the stringer operator 7 notifies the surveying operator to that effect. The stringer operator 7 stands the reference pile 44A at a place different from the placement position (X1, Y1) scheduled in the design. It is desirable to stand the reference pile 44A as close to the placement position (X1, Y1) as possible in the design.
[0037]
After collimating so that the reference pile 44A passes through the center of the optical axis of the telescope, the reference pile 44A is surveyed. Triangulation method may be used for surveying the placement position and height (X1 ′, Y1 ′, Z1) of the reference pile 44A, and the distance to the reference pile 44A is measured, and the calculation is based on the reference point T1. Can also be obtained.
[0038]
In any case, the reference pile 44A is set at a position where the rotation angle of the telescope is small enough to be regarded as being in the normal (MN) direction with a small deviation from the normal (MN) direction. Is desirable. Otherwise, the error with respect to the cut or fill as planned in the design may increase.
[0039]
First, the surveying operator measures the placement position (X, Y) of the reference pile 44A with the position where the reference pile 44A is set as the placement position (X, Y). After measuring the placement position, the stringer 7 drives the reference pile 44A into the ground 8 as shown in FIG. After driving the reference pile 44A into the ground 8, the surveying operator collimates with the telescope and rotates the telescope in the height direction so that the top end 44C of the reference pile 44A is located at the center of the optical axis. The casting height Z is measured. In addition, when measuring using a target prism, a placement position and height (X, Y, Z) are directly measurable. For example, as shown in FIG. 7, when the target prism 44E is provided at the height position of the offset height ZX from the top end 44C of the reference pile 44A, the height Z is
Z = (Z + ZX) −ZX.
[0040]
Next, the surveying operator collimates the telescope and causes the stringer operator 7 to stand so that the direction pile 44B is hidden behind the reference pile 44A. For example, the stringer operator 7 stands at a predetermined interval H3, for example, 1 m from the reference pile 44A, and positions the direction pile 44B based on an instruction from the surveying operator. And this direction pile 44B is driven in the ground 8. FIG.
[0041]
Thereafter, the surveying operator informs the tensioning operator 7 of the placement position (X, Y) and the placement height Z of the reference pile 44A by radio. The dressing operator 7 inputs the placement position (X, Y) and the placement height Z as the position information to the tension setting device 1. The tightness setting device 1 calculates the distance H1, the distance H2, and the inclination angle θ based on the position information and the design data. The distance H1, the distance H2, and the inclination angle θ are displayed on the display unit 3.
[0042]
As shown in FIG. 8, the tensioner 7 makes the horizontal plate 48 horizontal based on the distance H1, and spans the reference pile 44A and the direction pile 44B with the portion below the top end 44C by the distance H1 as the attachment position. Hit it.
[0043]
Next, the stringer 7 puts a mark on the mounting position in order to set the position of the horizontal plate 48 separated by the distance H2 in the horizontal direction with respect to the vertical axis 44D of the reference pile 44A as the mounting position of the cutting member 45. wear.
[0044]
Next, as shown in FIG. 9, the tensioner 7 applies the cutting material 45 to the mounting position of the horizontal plate 48 according to the mark, and the cutting material 45 is tilted by using a tilt angle measuring device (not shown). After setting so as to face the direction of θ, the cutting material 45 is struck against the horizontal plate 48. As a result, it is possible to quickly perform the tightening work without any trouble.
[0045]
