Description

TECHNICAL FIELD [0001] The present invention relates to a prefabricated retreading device for building a pipeline for easy installation and disassembly,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated earthmoving apparatus for construction of a pipeline which is easy to install and disassemble, and more particularly, to a prefabricated earthmoving apparatus for a pipeline construction which is easy to install and disassemble while preventing collapse of a wall surface of a crud.

In general, when constructing subways, pipelines, and large underground structures, temporary structures for earthworks are installed so that the surrounding soil or groundwater does not enter into the excavation ground.

Since these temporary structures are temporarily used and removed, safety and construction as well as economic efficiency are required at the same time.

The conventional anti-earth-sandwich panel brace is constructed such that a stretch brace having a movable portion formed on one side thereof and a movable portion on the opposite side thereof is formed between the anti-slip panels so as to support it. However, since the movable portion is formed by bolts and nuts, And there was an inefficiency problem because the operation time was slowed because quick adjustment was not made when the new construction was carried out.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same components are denoted by the same reference symbols whenever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIG. 1 is a perspective view of a conventional earthworking apparatus for pipeline construction according to an embodiment of the present invention. FIG. 1 is a perspective view of a conventional earthworking apparatus for a pipeline construction, (140).

The body part 100 includes a vertical part 110 and a horizontal part 120. The vertical parts 110 are separated from each other at positions where the pipe 10 is to be installed, And the horizontal portion 120 is a vertical H beam 111 and a horizontal H beam 111 horizontally laid between the web 112 and the web 112 between the vertical H beam 111 and the vertical H beam 111, 121 are positioned and formed by welding or bolting.

4, the vertical H beam 111 of the vertical part 110 includes a guide part 114 that allows the one of the flanges 113 to be coupled to the one of the flanges 113 by being fitted in a straight line, (115) spaced at a predetermined distance in the lower direction of the protrusion (114) to prevent the stretching part (140) from being drawn over a certain depth.

At this time, it is preferable that the flange 113 formed with the guide part 114 and the engaging part 115 is positioned in the direction in which the pipe 10 is positioned. That is, the guide portion 114 and the engaging portion 115 formed on the vertical H beams 111 located on both sides of the tube 10 are formed to face each other.

The horizontal part 120 has a steel plate insertion hole 124 formed in the longitudinal direction of the web 122 of the horizontal H beam 121 and a steel plate insertion hole 124 formed in the horizontal part 120 around the steel plate insertion hole 124. [ The steel plate pull-in guide portion 125 is further formed so that the steel plate portion 130 can be easily inserted into the insertion hole 124.

At this time, the steel plate pull-in guide portion 125 is provided at the outer upper end of the web 122 with respect to the steel plate insertion hole 124 so that the steel plate portion 130 to be drawn into the steel plate insertion hole 124 is guided outward at a predetermined angle So that the steel plate insertion hole 124 can be guided to the inside.

The web 122 of the horizontal H beam 121 which is the horizontal part 120 is further projected to both sides by the width of the one flange 113 of the vertical H beam 111 to form the flange 113 of the vertical H beam 111, To the web 112 between the flange 113 and the flange 113.

At this time, the vertical portion 110 and the horizontal portion 120 are welded or bolted to form one body portion 100.

The steel plate part 130 is coupled between the steel plate insertion holes 124 formed in the horizontal part 120 to support the earth wall to prevent the soil from collapsing.

Generally, the steel plate 130 used in a construction site is excellent in durability for safety, and is heavy in weight, so it is not easy to lift or move by the force of a person. Therefore, as shown in FIG. 5, the steel plate part 130 is formed with a ring-shaped moving part 131 at the upper end of the steel plate part 130 so that the steel plate part 130 can be coupled with the mobile equipment so as to be easily moved to the mobile equipment.

The thickness of the steel plate portion 130 is preferably set to be a thickness of the steel plate insertion hole 124 formed in the horizontal H beam 121, Is preferable.

The width of the steel plate part 130 is preferably equal to or smaller than the length of the steel plate insertion hole 124 formed in the horizontal H beam 121. [

The stretching part 140 is positioned between the vertical H beams 111 facing each other with the tube 10 interposed therebetween to support the steel plate part 130 so as not to collapse.

The supporting portion 140 includes an upper supporting portion 141 and a lower supporting portion 142 and includes a connecting portion 143 for connecting the upper supporting portion 141 and the lower supporting portion 142 on both sides thereof, And both sides of the lower support part 142 and the lower support part 142 are coupled with the connection part 143 and rotated up and down by the coupling shaft 144 of the connection part 143. [

As shown in FIG. 6, the upper support portion 141 and the lower support portion 142 are rotated up and down, so that insertion can be smoothly performed between the vertical H beam 111 and the vertical H beam 111, which are opposed to each other.

The rotation angle of the upper support portion 141 and the lower support portion 142 can be limited up to an angle that the rotation limiting means 145 located at the lower end of the upper support portion 141 and the lower end of the lower support portion 142, The upper supporting part 141 and the lower supporting part 142 of the supporting part 140 are positioned horizontally between the vertical H beam 111 and the vertical H beam 111 along the part 114, .

Here, the upper support portion 141, the lower support portion 142, and the connection portion 143 are integrally formed in a ladder shape.

Also, if the upper support 141 and the lower support 142 are not integrally formed by the connection 143 but are separately provided with the upper support 141 and the lower support 142, There is a disadvantage in that it takes a lot of time to adjust the level if it is not coupled by screw coupling.

The size of the pipe (10) to be installed at the time of pipe line construction is set as a standard, and when the treader is operated with the equipment used in the tearing operation, the treading operation is continued while maintaining a constant width. So that the steel plate portions 130 on both sides can be horizontally supported.

In addition, the prefabricated earth moving device according to the embodiment of the present invention is not a method combined with a complicated structure, but is easy to install and disassemble. Therefore, Since the pipe 100 can be separated from the steel plate part 130 and the brace part 140 and can be reinstalled at a position where the pipe line is extended, the piping work can be performed.

Therefore, the present invention is relatively simple in structure and integrated with the same standard, which facilitates installation and disassembly.

In addition, since the present invention is easy to install and dismantle, the construction period can be greatly shortened and the construction cost can be reduced.

The assembled earth moving device for pipeline construction which is easy to install and disassemble as described above is not limited to the configuration and the operation method of the embodiments described above. The embodiments may be configured so that all or some of the embodiments may be selectively combined so that various modifications may be made.
