Civil engineering structures such as drainage pipes on roads and roads, telecommunication cables and gas pipelines are equipped with civil engineering structures. The civil engineering structures are partially damaged due to aging or external impact on the civil engineering structures. There is damage to the back.

In the case of relatively small scale damage due to partial aging or partial destruction on the surface of civil engineering structures, partial repair is required for the maintenance of civil engineering structures. The maintenance of such relatively small area of civil engineering structures, Or the surface of the damaged portion is moved to a predetermined depth to achieve desired repair work.

The repair work of the relatively small area of the civil engineering structure is installed in a small heavy equipment such as a skid loader or a crane without detaching the large-sized special repair equipment in the past and a conventional grinder Grinding machine) is used.

A variety of such grinders have been developed and used so far, and they are mainly disk type disks.

The disc-shaped grinder is arranged in the circumferential direction of the grinding blades on the bottom surface of the substantially disc-shaped disc, and the disc-shaped grinder provided with the grinding blades is installed horizontally in parallel with the ground And the surface of the civil engineering structure to be repaired is rotated to a predetermined depth by the hydraulic motor driven by the driving source of the heavy equipment.

However, such a disk type grinder is installed at the work end of a small-sized heavy equipment and moves horizontally, and the epidermis of the civil structure is kept at a constant thickness.

Recently, there is a demand for a grinder capable of freely adjusting the removal thickness of the civil structure structure according to the degree of deterioration or deterioration of the civil structure to be repaired.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a grinder for surface maintenance of a concrete civil structure in which the thickness of a skin to be collected for partial repair in civil engineering structures can be freely adjusted .

It is an object of the present invention to provide a method and apparatus for easily removing the surface of civil engineering structures using heavy equipment such as forklans for repairing damaged portions when maintenance is required due to deterioration in a concrete civil structure or comparatively small- This grinder can be used for repairing damaged parts of a concrete civil structure by providing a grinder for repairing the damaged part of the concrete civil structure, such as aging or partial damage, The present invention relates to a grinding machine for grinding a surface of a civil engineering structure using a heavy equipment such as a grinding wheel, It is installed to be exposed to friendship, A drum type grinding body pivoted by a hydraulic motor operating in a circle, and adjusting means provided on one side wall of the housing for freely adjusting the grinding depth of the grinding body while raising and lowering, It is possible to freely adjust the thickness of the skin of the civil engineering structure to be collected.

According to the grinder for the surface repair of the concrete civil structure according to the present invention, it is possible to freely adjust the thickness of the skin to be collected for the partial repair in the civil structure, and thereby the repair can be carried out according to the aging condition of the civil structure or the degree of damage It is possible to improve the durability of the civil structure after repairing as well as the water retention due to the appropriate thickness of the epidermal removal of the civil structure.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view showing a crane equipped with a grinder for surface maintenance of a concrete civil structure according to the present invention; FIG.
2 is a front view of a grinder for surface maintenance of a concrete civil structure according to the present invention.
FIG. 3 is a partial cross-sectional view taken along line AA of FIG. 2;
4 (a) and (b) are explanatory views showing a grinding process of a grinder for surface repair of a concrete civil structure according to the present invention.

Next, an embodiment of the present invention will be described. 1 to 3 show a grinder for a surface repair of a concrete civil structure according to the present invention in detail.

The present invention relates to a civil engineering structure for installing a concrete civil structure, that is, a drainage pipe on both sides of a road, a communication cable, and a gas pipeline. In such civil engineering structures, And to provide a grinder for collecting the epidermis of civil engineering structures for repairing damages such as partial damage.

As described above, when relatively small-scale repair is required due to deterioration or partial destruction in concrete civil structures, the present invention uses a heavy equipment such as a forklänle to repair the damaged portion, A grinder for surface maintenance of a concrete civil structure, wherein 10 is a housing of a grinder.

The housing 10 is formed in a cap shape having an open bottom, and is provided with a mounting portion 12 which is hooked to and detached from the end of the heavy boom 100 at the upper end thereof.

In the housing 10 of the cap type, a grinding body 20 having a drum-shaped body is disposed in a horizontal direction so as to be parallel to the surface of the civil engineering structure to be repaired. The grinding body 20 includes a housing 10 so as to be rotated by a hydraulic motor 30 operating as a drive source of a heavy equipment.

In addition, high-strength grinding blades 22 are radially arranged on the outer circumferential wall of the drum-shaped grinding body 20 alternately with the radially adjacent side.

The housing 10 is provided at one side wall with adjustment means 40 for adjusting the grinding depth of the grinding body 20 by raising and lowering the housing 10 and the grinding body 20.

The adjustment means 40 includes a lift portion 42 that rides on guide rails 14 and 16 provided on both sides of the side wall of the housing 10 and moves on the surface of the civil engineering structure to be repaired on the bottom surface, Emphasizing portion 44 in the form of a barb type which is installed between the elevation portion 42 and the elevation portion 42 and rotates left and right to raise and lower the elevation portion 42. [

Here, the elevating portion 42 includes a lifting plate 42a that ascends and descends by the guide rails 14 and 16 of the housing 10, and a lower surface of the lifting plate 42a, And a slider 42b that moves on the slider 42b.

On the other hand, the adjusting means 40 may adjust the height of the adjusting means 40 by using a separate hydraulic method other than the bipolar method using the screw-up bar type emphasis portion 44.

4 (a) and 4 (b) are explanatory diagrams showing the process of surface treatment of a civil engineering structure of a grinder for surface repair of a concrete civil structure of the present invention.

4 (a) shows a reference value of the removal thickness of the skin for repairing the civil engineering structure in the grinder of the present invention.

4 (b) shows a state in which the thickness of the skin removal structure of the civil engineering structure is increased due to the aging of the civil engineering structure or the degree of deterioration in the state of FIG. 4 (a) The lifting portion 42 is raised to the upper side and the lower exposed portion of the grinding body 20 is increased by rotating the lifting portion 44 of the lifting portion 40 to increase the removing thickness of the civil structure structure.

While the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
