Description

Technical Field [0001] The present invention relates to an excavation surface roughness measuring apparatus and an analysis system,

TECHNICAL FIELD The present invention relates to an excavation surface roughness measuring apparatus, an analysis system, a method for measuring roughness of an excavation surface using the same, and an analysis method using the same. More particularly, the present invention relates to an excavation surface roughness measuring apparatus, an analysis system, and a method for measuring roughness of an excavated surface using the same, which can easily measure roughness of a rock excavation surface of a drilled pile with a semi-solid material protection portion.

In general, field drilled piles are structures used to transfer loads to deep grounds with high strength to compensate for insufficient bearing capacity when mounting structures on soft ground. 1 is a conceptual view showing an excavation surface of a cast-in-place pile. As shown in FIG. 1, such a ground drilled pile is configured to penetrate from a relatively soft soil layer to a relatively high strength rock bed. Since the frictional force on the relatively weak soil layer is relatively low, the frictional force on the rock surface of the drilled pile greatly affects the vertical bearing capacity of the drilled pile.

2 is a graph showing the relationship between the roughness of the rock excavation surface and the main surface friction force in relation to the main surface friction force of the rock bed. In Fig. 2, the abscissa represents the displacement, the ordinate represents the main surface friction force, and i represents the roughness. The higher the value of i, the more rough the surface is. As shown in FIG. 2, it can be seen that the roughness of the rock surface increases as the roughness of the rock becomes higher. Fig. 3 is three-dimensional data obtained by quantitatively evaluating the roughness of the rock excavation surface. Based on these data, the frictional force and the vertical bearing capacity of the cast-in-place pile are derived. Therefore, there is a need for an equipment for easily measuring the roughness of a rock excavation surface in the field.

In the related art, FIG. 4 is a photograph of a conventional excavation surface roughness measuring apparatus. As shown in FIG. 4, equipment for measuring the roughness of the excavated surface using the semi-solid material and shrinking expansion of the cylinder by the air pressure at a specific position downward from the upper part has been conventionally used.

However, this conventional technique frequently causes the semi-solid material to be damaged during the input and recovery of the measuring device, and the semi-solid material does not stick to the excavation surface due to the inclination of the excavation surface. The reliability of the roughness measurement was reduced due to the rotation of the shaft, and the number of times of measurement required for acquiring a large number of data was increased due to the two-direction measurement, and maintenance of the center of the measuring device in the excavation hole was not easy and the air pressure had to be controlled separately from the outside .

Therefore, there is a need for an excavation surface roughness measuring device for solving such problems.

The measurement mode of the excavation surface roughness measuring apparatus 100 according to an embodiment of the present invention means a mode in which the expansion and contraction means 120 expands and the semi-solid material 10 is brought into close contact with the excavation surface, The loading and lifting mode of the apparatus 100 means a mode in which the expansion and contraction means 120 contracts and the semi-solid material 10 is inserted into the semi-solid material protection portion 130.

The semi-solid material (10) is constituted such that one side is pressed against the excavation surface of the rock, and a pattern corresponding to the roughness of the excavation surface emerges. Here, the semi-solid material 10 is not water-soluble and oil-soluble material so that it can be used in water. It is preferable to use a material having a property of not being hardened even after storage for a long time so that it can be reused even after measuring the roughness of the excavated surface. As the material of the semi-solid material 10, it is preferable to use a soil, but the present invention is not limited thereto.

7 is a perspective view showing a compression plate according to an embodiment of the present invention. As shown in FIG. 7, the compression plate 110 has a structure in which the other side of the semi-solid material 10 is coupled to one side and directly applies pressure to the semi-solid material 10. The pressing plate 110 may include a first panel 111, a first hinge 113, a second panel 112, a second hinge 114, an elastic member 115, and the like.

The first panel 111 is brought into contact with the semi-solid material 10 at one side thereof. In addition, the first panel 111 may include at least one semi-solid material inlet hole into which a part of the semi-solid material 10 flows. Part of the semi-solid material 10 introduced through the semi-solid material inflow hole thus has the effect of preventing the semi-solid material 10 from falling off the first panel 111 when the semi-solid material 10 is squeezed onto the excavation surface, .

At least one first hinge 113 is provided on a side surface of the first panel 111 and at least one second hinge 114 is also provided on a side surface of the second panel 112. An elastic member 115 is provided between the first hinge 113 and the second hinge 114. Therefore, the first panel 111 and the second panel 112 are connected by the first hinge 113, the second hinge 114, and the elastic member 115. The first panel 111 is configured to be tilted at a predetermined angle with respect to the second panel 112. [ Therefore, the above-described structure according to an embodiment of the present invention has an effect that the first panel 111 can be tilted corresponding to the inclination of the excavation surface. This makes it possible to accurately measure the roughness even when the excavated surface is inclined.

A plurality of the expansion and contraction means 120 may be provided so as to have the same distance from each other on one plane. In this case, the pressure generated by the expansion / contraction means 120 is balanced so that the center of the excavation surface roughness measuring apparatus 100 is not eccentric. In one embodiment of the present invention, four expansion shrinking means 120 each having an angle of 90 degrees are provided, so that the four semi-solid materials 10 can be accommodated. It is possible to improve the amount of roughness data that can be obtained in one measurement and to reduce the number of times of measurement to ensure the convenience of measurement and to reduce air and construction costs It is effective.

In addition, a pneumatic distribution device 400 may be provided at the center of the excavation surface roughness measuring apparatus 100 to which the other ends of the respective expansion and contraction means 120 are connected. This pneumatic distribution device 400 has the effect of solving the unevenness of the accessories due to the increase of the directionality by bundling the air pressure for expanding and contracting the expansion / contraction means 120 in the four directions. That is, there is an effect of minimizing the pneumatic wiring 121. The pneumatic distribution device 400 is connected to the control means 150 and the pneumatic wiring 121. The pneumatic wiring 121 includes shrinking and expansion wiring and the pneumatic distribution device 400 is a pneumatic wiring 121 to provide shrinking and expanding pneumatic pressures to the respective expansion and contraction means 120.

The expansion and contraction means 120 is coupled to the moving member 170 at one end and moves the moving member 170 in the longitudinal direction by driving (expansion and contraction) of the expansion and contraction means 120. Therefore, the pressing plate 110 coupled to the end of the moving member 170 is moved by the movement of the moving member 170. When the excavation surface roughness measuring apparatus 100 is inserted into the excavation hole and is changed between the input and salvage mode and the measurement mode, it will move in the radial direction of the excavation hole cross-section.

This moving member 170 can be configured to have a polygonal cross section to prevent the pressing plate 110 from rotating. This is closely related to the accuracy of the roughness data. According to this configuration, the equipment for preventing the rotation of the presser plate 110 is simplified, and the equipment cost is reduced. The moving member 170 according to an embodiment of the present invention has a hexagonal cross section. One end of the expansion and contraction means 120 is formed with a hexagonal hole that is shaped to fit with the outer periphery of the moving member 170 and the moving member 170 is configured to slide in contact with the hexagonal hole, Prevent rotation.

These extension rods can be coupled to both sides of the expansion and contraction means 120 by engagement members 122. The excavation surface roughness measuring apparatus 100 may be used in an oyster vacuum of 1.5 m or less in diameter at the time of the maximum expansion of the expansion shrinking means 120 according to an embodiment of the present invention. In the case of measuring the roughness of the excavation surface in a oyster vacuum of 1.5 m or more in diameter, these extension rods can be used by tightening.

The semi-solid material protection unit 130 may be configured to surround the compression plate 110 and the semi-solid material 10 at one end of each expansion and contraction means 120. And serves to protect the semi-solid material 10 in the loading and lifting mode of the excavation surface roughness measuring apparatus 100. This is because when the semi-solid material 10 is brought into contact with the excavation surface, the semi-solid material 10 having the roughness pattern is damaged and the precision of the roughness data is reduced. The semi-solid material protector 130 is in the form of a case, one side of which is closed, and the other side of which is opened to move the compression plate 110 to the other side that is open.

The wire 180 is connected to the depth adjusting device 300 so that the excavation surface roughness measuring apparatus 100 can be put into or taken out of the excavator.

In addition, a rotation preventing guide formed in the longitudinal direction of the expansion and contraction means 120 may be provided on one side of the semi-solid material protection portion 130. The rotation preventing guide may be formed of a groove or a hole. One side of the pressing plate 110 is connected to the rotation preventing guide and moves along the rotation preventing guide, so that the pressing plate 110 moves the moving member 170 There is an effect of preventing rotation about the axial direction. This is closely related to the accuracy of the roughness data.

The control means 150 is connected to the expansion and contraction means 120 and the pneumatic wiring 121 so as to control the expansion pressure of the expansion and contraction means 120.

So as to prevent the shape of the semi-solid product 10 from being deformed.

With respect to intrusion device 320, FIG. 8 is a side view illustrating intrusion equipment in accordance with an embodiment of the present invention. 8, the intrusion equipment 320 is provided at one side of the introduction port of the oyster vacuum, and may include a stringer and a beam. At the end of the stringer and the beam, a first sheave 322, A wire 323 may be provided to guide the wire 180 to be driven in the vertical direction. According to the intrusion apparatus 320 according to the embodiment of the present invention, it is possible to adjust the length of the beam to facilitate mounting of the excavation surface roughness measuring apparatus 100 at the center of the transverse section of the excavation hole. Also, since the intrusion equipment 320 according to an embodiment of the present invention is mounted on the upper end of the oyster casing surface, it is very advantageous to secure stability in the insertion and lifting of the excavation surface of the excavation surface roughness measuring apparatus 100 There are advantages.

Particularly, in the first pulley 322 or the second pulley 323, a depth measuring device (not shown) for measuring the depth of insertion of the excavation surface roughness measuring device 100 using the principle that the pulley is rotated when the wire 180 descends 324 may be further provided. This depth measurement device 324 can easily confirm intrusion depth of the excavation surface roughness measuring apparatus 100.

That is, it is possible to adjust the air pressure while confirming the operating condition of the excavation surface roughness measuring apparatus 100, thereby maximizing convenience in equipment operation. The air pressure regulating device 326 includes another structure capable of adjusting the expansion and contraction of the expansion and contraction means 120 according to the type of the expansion and contraction means 120, and is not limited to the adjustment of the air pressure.

The depth adjusting device 300 may be a winch or the like and may be connected to the wire 180 to pull or loosen the wire 180 extending from the penetration equipment 320 to measure the depth of the excavation surface roughness measuring device 100 .

Hereinafter, the operation of the excavation surface roughness measuring apparatus 100 and the method of measuring excavation surface roughness according to an embodiment of the present invention will be described.
