Description

Concrete pile setting method by utilizing an auger drilling maachine}

The present invention relates to a method for constructing a rectangular concrete pile through an auger drilling machine, and more particularly, not only can a sheet pile be inserted into a high vertical body, but also shorten the working time and can be generated in a working process. The present invention relates to a sheet pile construction method through an auger drilling machine that can minimize the risk of component damage.

In general, when placing a port (beam) for foundation work using auger drilling machine, which is widely used, a leader mounted on a crane is erected vertically and rotated 90 degrees by a leader turning device. Therefore, a hole is drilled to a certain depth with a screw rotating by an auger, and then the beam is cast.

Such a conventional auger drilling machine is capable of pulling the casing formed on the outside of the auger drill to the wire formed on the top of the rudder to press the casing formed inside the auger drill into the vertical hole drilled by the auger drill If the tip of the vertical shaft drilled by the auger drill is a soft ground, the ground drilling can be easily performed. However, in a hard ground such as a rock, the auger drill and the casing cannot be inserted by magnetic force. .

In the conventional auger drilling machine, perforated soils such as clay and nito are firmly adhered to the upper surface of the auger drill, but foreign matters such as perforated soil stuck to the upper surface of the auger drill prevent the groundwork of the perforated soil from drilling. There was a problem of being an obstacle.

In order to solve this problem, the applicant has proposed an improved auger drilling machine through the registration number 20-444957.

That is, as shown in FIGS. 1 to 5, the auger drilling machine 100 pre- filed by the applicant has a rudder 112 that is rotated by a rotating device on an upper portion of the crane 111 that supplies power while moving to a working position. And a plurality of driving pulleys 116 having wires 117 operating on the power of the crane 111 on the upper part of the rudder 112 with the pulley bracket 115, A rudder portion 110 having a rudder guide 114 formed on the perforation side, and a transfer pulley 122 having the wire 117 of the rudder portion 110 formed thereon are formed on an upper portion of the transfer bracket 121, and a transfer bracket A transfer guide 124 which is coupled to the rudder guide 114 to one side of the 121 and a transfer part 120 having a transfer coupling hook 123 formed at the bottom of the transfer bracket 121 and the transfer part ( The fixed coupling hook 133 is hingedly fixed to the upper portion of the fixed frame 131 to be coupled to the transfer coupling hook 123 of 120. Hinge fixed by the hook hinge 134 provided in the, and coupled to the rudder guide 114 to one side of the fixed frame 131 to form a fixed guide 132 guided during the vertical operation, the fixed coupling of the hook 133 The cylinder rod 139 of the operation cylinder 137 fixedly coupled to the fixed frame 131 by the cylinder fixing hinge 138 to one side is hinged by the hook operation hinge 136 to be fixed by the operation of the operation cylinder 137. A transfer fixing part 130 formed to operate the coupling and disassembly of the transfer coupling hook 123 of the transfer part 120 while the hook 133 rotates about the hook hinge, and a fixed frame of the transfer fixing part 130. When driving the auger drill 141 in the lower portion of the (131) to form a driving guide 143 is coupled to the rudder guide 114 to one side of the drill driving unit formed up and down operation cylinder 144 to operate up and down, Auger with casing 146 on the outer side driven under the drill drive In the auger boring machine comprising a five reject 140 to form a reel (141). The auger 140 is formed by extending the extension guide 146 formed with the guide groove 147 to the lower side of the casing 145 to the lower side to be poured into the hole drilled by the auger drill 141. (Sheet file) is configured to guide.

However, in the auger drilling machine of the present applicant, there is a problem that it takes a lot of time to draw the casing after drilling due to friction between the seat pile connecting ring and the guide groove of the extension guide.

In addition, when attempting to construct a rectangular concrete pile as a cast body rather than a sheet pile, the above problems will be very large.

The present invention was created to solve the problems of the above-described auger drilling machine previously filed by the present applicant, in addition to the advantages of the existing guide groove can prevent friction between the guide groove of the rectangular concrete pile and the extension guide, in particular the construction The purpose is to provide a square concrete pile construction method of the auger drilling machine that can be made stable to shorten the working time and cost reduction.

Square concrete pile construction method of the auger drilling machine according to the present invention in order to achieve the above object, the process of extending and forming an extension guide formed with a guide groove in the lower side of the casing of the auger; Axially rotatably supporting a plurality of rollers at predetermined intervals inside the guide groove of the extension guide; Providing a guider having a rectangular cross-sectional shape between the rollers; Mounting a rectangular concrete pile to be installed by mounting a vibrator on a crane; The step of adjoining and puncturing the groove of the square concrete pile in the adjacent guide guide of the extension guide; characterized in that consisting of.

The guider disposed between the rollers of the present invention is formed of a metal, is installed to protrude lower than the roller, and at the same time the auxiliary guider made of a square iron piece and a cylindrical pipe welded to the casing on the left and right outer sides of the guider. It is characterized by being further provided.

The roller of the present invention has a long and rectangular cross-sectional shape having the same cross-sectional shape as the rectangular concrete pile, characterized in that the iron plate of the same shape is interposed between each other.

An engaging shaft portion between the roller and the extension guide of the present invention is characterized in that the O-ring is interposed.

The vibrating letter of the present invention is characterized in that the air hose for injecting air into the groove formed in the center of the rectangular concrete pile is provided.

As described above, the method for constructing the square concrete pile of the auger drilling machine according to the present invention may be drilled through the extension guide by entering through the vibratory letter of the square concrete pile crane, and in particular, the extension guide and the auxiliary guide and the air hose during the drilling process. It is possible to stably drill through the back.

In addition, due to the interaction between the shape of the roller and the groove of the rectangular concrete pile body, it can be drilled firmly without shaking.
