It should be understood that the embodiments according to the concept of the present invention are not limited to the particular mode of disclosure but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

Since the present invention uses the following Japanese Patent Application No. 0973591 as it is, all the features of the device configuration described below can be understood as the matters described in Patent Registration No. 0973591. [

However, the present invention is not limited to the structure disclosed in the above-mentioned Japanese Patent No. 0973591, in which 'one person measurement target for measuring the real time position of underground facilities is replaced with' real time position measurement device for underground facilities' And a description of its operation is further included, and this part constitutes the most essential constitutional feature.

Accordingly, the device structure, characteristics and operation relationship described below will be incorporated by reference in the above-mentioned Japanese Patent Application No. 0973591, and the configuration related to the main features of the present invention will be described in detail at the rear end.

1 to 3, an underground facility real-time position measuring apparatus (hereinafter referred to as "surveying apparatus") 100a according to the present invention can measure the position and depth of various underground facilities buried in the underground, Which is attached to the underground facility and is a target of measurement of a public measurement instrument 200 such as a total station.

The measuring apparatus 100a is configured to be adjustable in length so that it can be detected by the measuring equipment 200 located on the ground regardless of the depth of buried underground facilities.

1 (a) and 1 (b), the measuring apparatus 100a includes a stator 110 connected to an underground facility, a hinge (not shown) fixed to the stator 110 120, and a rod 130 rotatably fixed to the hinge 120.

The rod 130 includes a tubular matrix 131 whose lower end is connected to the hinge 120 and a self 132 which adjusts the length of the rod 130 while being inserted or removed along the longitudinal direction of the matrix 131 .

It is also possible to connect two or more members 132 in series with the matrix 131 so that the longest length of the rod 130 reaches several times the shortest length.

In other words, the length of the rod 130 can be adjusted in such a manner that the rod 132 according to the present invention is drawn out from the matrix 131 by applying a conventional rod antenna connection structure to the rod 130 according to the present invention.

A vertical weight 131a may protrude from the lower end of the base 131, which is rotatably connected to the hinge 120.

The vertical weight 131a is a protrusion protruding in the form of a horn in a downward direction. In the course of rotating the bar 130 with respect to the hinge 120, the vertical axis 131a indicates where the lower end of the bar 130 faces the ground, So that it can be measured.

At this time, since the interval between the vertical weight 131a and the ground (or one point of the underground facilities) is not relatively long, the measurer can recognize the direction of the vertical weight 131a roughly and relatively accurately, 200 can track which location of the underground facility corresponds to the location of the surveying apparatus 100a.

A scale (not shown) may be formed on the outer surface of the rod 130. The scale allows the measurer to measure where the aiming point of the surveying instrument 200 is and can calculate the position of the underground facility indicated by the surveying instrument 100a on the basis of this.

The stator 110 is attached and fixed to one point of the underground facilities, and is preferably made of a magnetic material with a certain weight.

Generally, underground facilities are mainly made of metal materials, especially magnetizable iron.

When the stator 110 is made of a magnetic material in consideration of the characteristics of the underground facilities, the measurer of the site may be provided with the measuring apparatus 100a of the measuring apparatus 100a by the stator 110 The measurement apparatus 100a attached to the underground facilities can stably maintain the current position by being resistant to various natural forces such as winds even if the other measurer does not hold it, The user can perform accurate position measurement alone.

It goes without saying that the stator 110 may be manufactured to have a certain weight or more so that the self weight of the stator 110 may exhibit an anchor function even in an underground facility of non-conductive material.

The hinge 120 is a means for pivotally connecting the stator 110 and the rod 130 to each other in a rotatable manner and is fixed to the stator 110 via the rotating shaft 122. The rod 130 is fixed to the fixing means 121 .

The rotating shaft 122 is rotatably engaged with the stator 110 so that the hinge 120 can be rotated by the stator 110 about the rotating shaft 122 and the holding means 121 rotates with the stator 110 Shaped frame 123 and a bolt 121a rotatably penetrating the bar 130 and a nut 123 that presses the bar 130 to tighten the bar 130 to maintain the current state, (121b).

Therefore, the measurer adjusts the position of the rod 130 according to the field conditions and then tightens or loosens the nut 121b so that the nut 121b moves along the bolt 121a, The current position can be maintained.

The hinge 120 allows the measurer to move the rod 130 relative to the stator 110 to match the vertical position of the rod 130 in the field, as well as to maintain the vertical position of the aligned rod 130 And to fix it so that it can be used.

That is, the measurer can rotate the rod 130 in the state of releasing the tightening of the nut 121b, align the vertical state thereof, and tighten the nut 121b again so that the hinge 120 can hold the rod 130 It is.

On the other hand, the vertical state of the rod 130 can be confirmed through a known bubble tube (not shown).

The bubble tube can be detachably fixed to the upper end of the rod 130 by confirming the movement of the bubble and allowing the measurer to visually confirm the horizontal state of the object on which the bubble tube is installed. 4), the rod 130 can be rotated while the bubble position of the bubble tube disposed at the uppermost end of the rod 130 is visually confirmed, thereby adjusting the rod 130 to a vertical state.

The total station is a public measuring instrument 200 capable of measuring an angle and a distance together. The electronic station includes an electronic theodolite and electro-optical instruments (EDM) , And an electronic measuring / measuring instrument that can process measured data quickly and output the results. The types include a lightwave-wide-wave-side main body type in which a lateral wave function is added to a general-purpose wave side terrestrial wave, an optical type lightwave main body type in which an optical wave side girder is attached to an optical type lightwave, and an electronic type lightwave type .

A typical structure of the total station is composed of a tripod 210 for stable support and a main body 220 supported and fixed to the tripod 210.

The main body 220 includes a light wavefront detector 221, a vertical angle detection unit (not shown) for measuring the vertical angle caused by the vertical movement of the optical wavefront transducer 221, a horizontal angle And a tilting sensor (not shown) for measuring and correcting the level of the main body 220. [0064]

In the beginning, the conversion of the horizontal distance and the height difference is separately calculated later. However, since the calculation function is incorporated in the optical wavefront detector 221 due to the development of the electronic technology and the detection unit for measuring the vertical angle and the horizontal angle gradually becomes smaller and lighter, I have a shape.

As the types of the total station, there are a light wave side direction main body type that adds a side angle function to the optical wavefront side girder 221, an optical type semiodolite main body type that the optical wave side wave source 221 is attached to the optical type light stone, An electronic cedarite main body type having a photoreflector, and the like.

The measuring apparatus 100a is packaged with a retroreflective film 130a in the form of a film for retroreflection on its surface.

Reflective reflection means a phenomenon in which light from a light source is reflected from a surface of an object and returns to the light source. Regardless of the angle of light emitted from the light source, the retroreflective 130a reflects the light .

As is widely known, the retroreflective member 130a has concavities and convexities formed in a concave shape in the form of a curved surface or a trilobal, and when the trilobal shape is applied, .

A method of performing the measurement apparatus 100a will now be described with reference to FIG. 4. The underground facility 10 to be buried in the cutout 30 is installed for the burial of the underground facility 10, Before re-filling, the surveyor may install the surveying target 100a according to the present invention in the underground facility 10 to confirm the location of the underground facility 10. [

In this case, when the underground facility 10 is made of a magnetizable metallic material, the stator 110 having the magnetism formed on the survey target 100a is magnetically connected and fixed to the survey target 100a and the underground facility 10, So that the surveying target 100a can be stably placed in the underground facility 10 without collapse.

In addition to the underground facility 10, other underground facilities 20 may be buried together in the cutout 30 and the buried position of the other underground facilities 20 may be buried in the cutout 30, Location.

Therefore, when the arrangement of the underground facilities 10 and 20 is as shown in the drawing, it is difficult to measure the position of the underground facility 10 located at the lower part, as a straight bar-shaped survey target.

However, since the surveying target 100a according to the present invention is constructed so as to be rotatable via the hinge 120, the bar 130 of the surveying target 100a can be avoided, And the bar 130 of the surveying target 100a drawn straight from the cutout 30 is detected by the surveying equipment 200 and the actual buried position of the underground facility 10 located at the bottom is measured Can be measured.

The bar 130 is rotatable with the stator 110 via the hinge 120 so that the outer surface of the underground facility 10 on which the stator 110 of the measurement target 100a is placed is inclined or not flat Even if it is a curved surface, it is possible to position the rod 130, which is based on the stator 110, to be always straight. For reference, since the underground facilities 10 and 20 in the urban area are embedded in the adjacent sewer lines, various communication lines and underground lines are adjacent to each other, it is difficult to check the position of the subterranean facilities 10 and 20 by neighboring underground facilities 10 and 20 .

However, since the surveying target 100a according to the present invention can avoid the interference of the neighboring other underground facilities 10 and 20 and can precisely confirm the location of the underground facilities, the location information of the underground facilities There is an advantage that the construction work can be performed accurately and relatively easily.

In the present invention, as shown in FIG. 5 to FIG. 7, the lock 132 is coupled to the mother body 131 to maintain the adjusted length of the rod 130, (140) is further implemented.

The locking portion 140 may be formed in a shape such that the adjusted length of the rod 130 due to the lifting movement of the self 132 is less than the load of the self 132 or the pressure or impact transmitted from the outside to the self 132 Thereby preventing a return to the state before being adjusted.

This is because it is difficult to maintain the adjusted length because the mother body 131 and the mother body 132 are connected in a length-adjustable manner using a conventional connection structure.

To this end, the mother body 131 is formed with a guide hole 131a extending in the longitudinal direction on one side thereof and communicating with the inside thereof.

The locking part 140 includes a guide bar 141 having one end connected to one side of the self 132 and the other end passing through the guide hole 131a and forming a thread on the outer circumferential surface, And a locking member 142 screwed to the guide bar 141.

The guide bar 141 is provided on one side of the lower portion of the self 132 and is connected to the self 132 without being separated.

The guide bar 141 and the lock member 142 may be formed in a plurality of ways depending on the length of the self 132, the load, and the like.

At this time, the plurality of guide bars 141 should be spaced apart from each other in the longitudinal direction of the self 132.

It is preferable that the guide hole 131a does not extend to the upper and lower ends of the matrix 131.

This is to prevent the guide bar 141 which is lifted and lowered along the guide hole 131a from being separated from the self 132 while preventing the self 132 from colliding with the hinge 120 to be.

The locking member 142 may be formed of a nut or the like and may be coupled to the mother body 131 while advancing in the longitudinal direction of the guide bar 141 according to the tightening or loosening rotation, 131).

That is, the locking member 142 is brought into contact with the main body 132 according to the tightening rotation, and the main body 132 is brought into contact with the main body 131 so that the main body 132 is bound.

The lock member 142 is spaced apart from the self 132 by the rotation of the lock member 142 so that the self 132 is separated from the main body 131 to release the binding of the self 132.

The locking unit 140 may further include an auxiliary locking unit 143 for preventing the locking unit 142 from falling down due to imperfect binding or the like of the locking unit 142.

The auxiliary locking means 143 may change the position of the measuring apparatus 100a due to the variation in the length of the rod 130 due to the automatic lowering of the self- So that a smooth measurement can be made.

The auxiliary locking means 143 includes a metal plate 144 disposed on one side of the guide 132 and a guide groove 141 disposed on the upper side of the guide plate 141 to face the metal plate 144, And a magnet member 145 provided on one side.

It is preferable that the distance between both sides of the matrix 131 is longer than the distance between both sides of the matrix 132 itself.

The metal plate 144 may extend in the longitudinal direction of the self 132 and may be embedded so as not to protrude from the surface of the self 132.

The metal plate 144 is attached to the magnet member 145 by abutting on the matrix 131 according to the tightening rotation of the lock member 142.

The metal plate 144 is separated from the magnet member 145 by being separated from the matrix 131 due to the release rotation of the lock member 142.

The magnet member 145 is preferably rotatably connected to the upper portion of the matrix 131 by a folding member 146 such as a hinge.

That is, the magnet member 145 is rotated in the direction opposite to the metal plate 144 when the length of the magnet member 145 is adjusted according to the lifting and lowering of the magnet 132, So that it is not interrupted.

The magnet member 145 is attached to the metal plate 144 while being rotated in the direction of the metal plate 144 together with the tightening rotation of the lock member 142 in accordance with the length adjustment of the self 132, Thereby preventing automatic descent of the battery.

The locking member 142 is locked by the auxiliary locking means 143 so that the locking member 142 is locked to the base body 131 to prevent the locking member 142 from falling down even when the locking member 142 is incompletely engaged. The adjusted state can be maintained.

Therefore, the locking part 140 can prevent the self-lifting part 132 from falling due to its own load, pressure or impact transmitted from the outside, It is possible to smoothly perform real-time position measurement of the vehicle.

It is preferable that the mother body 131 has an outflow inlet 131b extending from the upper side to the lower side on the other side so that the mother body 131 and the mother body 131 can be smoothly separated and coupled with each other.

That is, the outflow inlet 131b is inclined downward in the direction of the outflow inlet 131b from the state where the self 132 is vertically formed when the matrix 131 and the self 132 are coupled, So that the guide bar 141 can be smoothly inserted into the guide hole 131a.

The outlet 131b is inclined downward in the direction of the outflow inlet 131b when the body 132 is separated from the body 131 and the upper end of the outlet 131b is perpendicular to the outlet 131b, So that the guide bar 141 can be smoothly drawn out from the guide hole 131a while being drawn out from the mother body 131. [

Therefore, the measurement apparatus 100a can be separated and stored between the models 131 and 132, and can be separated and stored for maintenance, repair, replacement, and unused.
