Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ground settlement measuring system using a reflection member and a light wave distance measuring apparatus,

The present invention relates to a ground settlement measuring system. More particularly, the present invention relates to a ground settlement measuring system and an apparatus for accurately and simply measuring a deformed state of a ground.

The method of measuring ground subsidence is usually a method using level measurement and a method using surface ground penetration.

In the method of measuring the ground settlement using the leveling, the floating point which is not affected by the excavation is installed near the site, and the tip of the rod supported on the settlement plate at the position to be measured is measured by the leveling measurement, There is an advantage that the installation cost for carrying out leveling is low. However,

It is necessary to continuously move the measurement point along the road, so that it takes a lot of time for measurement, and the work is very dangerous on the road on which the vehicle is traveling.

The ground settlement measurement method using the ground subsidence system consists of perforating the floor to the same level as the rock bed at the point to be measured, mounting the anchor, fixing the pipe to the floating floor, As a method of measuring the ground settlement by the difference, that is, the relative displacement difference, there is an advantage that the change of the ground can be measured according to the installation position of the anchor,

Since the pipe must be buried to the depth of the floating layer, it is known that it takes a lot of installation cost and it is difficult to measure the relative position between the points.

In order to overcome the above-mentioned disadvantages, a sinking pin having a sinking plate fixed is provided at a position to be measured, and a reflecting member, which moves simultaneously with the sinking pin, is provided at the tip of the sinking pin, A ground settlement measuring apparatus and a method for measuring the settlement amount of the ground are provided so that the deformation state of the ground can be simply and accurately measured by collimating the reflecting member and measuring the settlement amount.

In a system and an apparatus using the reflective member according to the present invention, a registered trademark 501041 (2005.07.05) is provided, and as shown in Figs. 1 and 2,

A light wave distance measuring instrument installed at a floating point which is a reference point;

A housing embedded in the ground in the ground of the ground settlement measuring point and penetrating both sides thereof and having an internal space portion;

A sinking pin installed in the longitudinal direction of the housing and having a lowering plate fixed to the lower portion thereof;

A stationary supporter coupled to an upper end of the sinking pin in a state of being located inside the housing;

And a reflecting member which is supported by the fixed support part and moves according to the rising or rising of the sinking pin and reflects the light wave emitted from the light wave distance measuring device,

Wherein the reflection member comprises an attachment plate which is rotatably supported by a fixing member in a fixed support portion and a reflection sheet which is attached to one side of the attachment plate and reflects the light wave emitted from the light wave distance measuring device,

A protection cap is provided on the upper portion of the housing to prevent damage to the reflective member caused by a vehicle or the like.

Incidentally, in the case of the background art described above,

The mounting plate of the reflecting member is fixedly supported by the fixing member at both sides of the fixing support member and is rotatable about the horizontal axis of the fixing member, and the rotation can be rotated only in the vertical direction.

Therefore, even when a predetermined rotation angle is set by performing the rotation, if an external force acting on the fixing member surface or edge far from the axis for performing the rotation is generated, the rotation angle is deformed, . Even if the rotation angle is fixed by the fixing means, the structure is always affected by the external force acting in the vertical direction.

In order to solve this problem, it is possible to cover the protective cap. However, the protective cap may cause shadows to obstruct the reflection of the light wave of the reflection member, or to reduce the reflection efficiency of the light wave.

In an actual field, an external force is often applied to a vertical direction due to passing of a vehicle, falling of a natural force, an object, or an artificial activity of a person. Due to this, if the predetermined rotation angle is changed, accurate light wave distance measurement may not be performed. There is an error in the measurement value.

The present invention aims to provide a simple, quick and accurate measurement of the deformation state of the ground by securing a reliable measurement value of the light wave distance measurement value by minimizing the influence from the vertical external force of the fixing member to which the reflecting member is attached .

In order to solve the above-described problems, the ground settlement measuring system using the reflection member and the light wave distance measuring instrument of the present invention,

A light wave distance measuring instrument installed at a floating point which is a reference point;

A sinking pin disposed in a vertical direction and having a lowering plate fixed thereto;

A fixing unit coupled to the upper end of the sinking pin so as to be horizontally rotatable;

A rotating unit fixed to the fixing unit so as to be inclinedly rotated;

And a reflecting member which is supported by the rotating unit and ascends and descends according to the rising or rising of the sinking pin and reflects the light wave emitted from the light wave distance measuring device,

Wherein the reflective member comprises: an attachment plate; A reflection sheet attached to an upper surface of the attachment plate and reflecting a light wave emitted from the light wave distance meter; And an attachment protrusion protruded downward from the attachment plate and fitted and fixed to an upper end of the rotation unit.

According to the ground settlement measuring system using the reflection member and the light wave distance measuring instrument of the present invention,

It is possible to measure the deformation state of the ground easily and precisely by measuring the settlement amount by collimating the reflecting sheet with the light wave distance measuring instrument,

Regardless of the protective cap, it is possible to minimize the influence of the reflection member attachment plate on the vertical external force, thereby maintaining a predetermined rotation angle at all times, thereby securing a reliable measurement value of the light wave distance measurement value.

First, in the drawings of FIGS. 1 and 2, the above-mentioned background art relating to the present invention will be described in more detail.

The reflection member is composed of an attachment plate which is rotatably supported by a fixing member on a fixed support, and a reflection sheet which is attached to one side of the attachment plate and reflects the light wave emitted from the light wave distance measuring device.

In addition, the method may further include the steps of: setting the sinking pin to which the reflection sheet is fixed at the upper end at a plurality of points to be measured;

Measuring and setting a floating point which is a reference point higher than the vicinity of the sinking pin so that the reflection sheet of the sinking pin can be confirmed without the influence of excavation;

The present invention provides a ground settlement measuring method for measuring a settlement amount by collimating the reflective sheet of settlement pins installed using a light wave distance measuring device on the basis of the floating point.

As shown in the figure, a housing 2, which is embedded in the longitudinal direction of the ground G at a point where the ground settlement is to be measured and through which both sides pass, and a space inside the housing 2, A fixed support portion coupled to an upper end of the sinking pin in a state of being located inside the housing, a movable support supported by the fixed support portion and moved together with the sinking pin of the sinking pin, And a reflecting member for reflecting light.

The housing 2 may be formed in a cylindrical pipe shape having a predetermined length and diameter. The housing 2 shields foreign materials and the like from entering the interior of the housing.

A plurality of drain holes (10) are formed in the housing (2) so that water introduced into the housing (2) can be drained to the outside.

A threaded portion 12 is formed at an upper end of the sinking pin and an extended portion 14 is formed at a lower portion of the fixed support portion. A thread portion corresponding to the threaded portion 12 is formed in the extended portion 14, And the fixed support portion can be coupled with each other.

The fixed support portion connected to the sinking pin has a space formed therein, an upper portion formed as an opening portion, and a reflecting member rotatably fixed to the inside of the upper portion thereof with a fixing member.

The reflecting member is fixedly supported by the fixing member 16 on both sides of the fixed supporting portion so as to be vertically rotatable about the fixing member 16. The reflecting member includes an attachment plate 18, And a reflection sheet 20 attached to one side of the reflection sheet 20 and reflecting the light wave emitted from the light wave distance meter.

After a plurality of measuring apparatuses are installed at positions where the ground subsidence is to be measured in this manner, the position coordinates of the reflective sheet 20 are respectively measured and recorded at a reference height.

In this state, the ground can be settled or raised when a certain period of time elapses. At this time, when the soil around the settlement plate installed on the ground (G) sinks or rises, the settlement plate is lowered or raised together with the soil, The mounted fixed support also descends or rises and the position of the reflective member changes.

At this time, a floating point serving as a reference point is measured and installed on the roof of the building (B) in the vicinity of the adjacent building so that the reflecting member / reflecting sheet 20 can be confirmed without the influence of excavation.

The reflection sheet 20 of the measuring apparatus installed in the ground G is collimated using the light wave distance measuring device 24 based on the floating point to measure the position coordinates of the reflection sheet, Compared with the height, the ground settlement amount can be known.

The light wave distance measurer 24 measures a point at which the light reflected from the reflective sheet 20 is reflected by the reflection member / reflective sheet 20 at the measurement point and converts the measured light into coordinates, (24) may be used as is commonly used in civil engineering work or construction work.

Since the light wave distance measuring unit 24 can display the position coordinates in three dimensions, it is possible to measure the subsidence or ridges of the ground in three dimensions. At this time, the coordinates of the national branch and the national reference point can be utilized.

When the height of the building in the vicinity of the ground is low or the measuring apparatus is installed on an inclined surface or the like and thus the reflection sheet 20 can not be confirmed in the measurement of the ground settlement, the mounting plate 18 supported on the stationary support portion is rotated And the inclination angle of the reflection member attachment plate is adjusted so that the reflection member / reflection sheet is visible.

3 and 4, the present invention includes a fixing unit 200, and the fixing unit 200 includes a cylindrical fixed body 210; A fixed inclined surface 220 formed by machining / forming a cam-shaped inclined surface on the upper end of the fixed body 210; Is formed at the lower end 230 of the fixed body 210 by concave / perforated corresponding to the shape of the horizontal rotation protrusion c10 so that the horizontal rotation shaft c is sandwiched by the horizontal rotation protrusion c10 A horizontal rotating recessed portion c20; A fixed body shaft hole (a23) formed at the center of the ellipse of the fixed inclined surface (220) by perforating a hole perpendicular to the fixed inclined surface (220); And a screw tightening room (a21) formed by drilling a wider diameter at the lower end of the fixed body shaft hole (a23).

Therefore, the grip handle 340 is configured to be inclined as viewed in the outside, such as the rotary body shaft hole a22.

Meanwhile, the screw tightening room a21; The fixed body shaft hole a23; The rotary body shaft hole (a22) together form an inclined rotary shaft hole (a20).
