The present invention is a method for embedding a pile in a method of embedding a concrete pile into a casing auger (Casing Auger) that excavated the pile ball in the ground using a ground excavator, and the casing to rotate the casing Method for embedding the demolition file of Oga Drive Unit and Casing Oga in ground excavator that allows concrete pile to be inserted in the state that excavated pile hole without dismantling of Drive Unit in Casing O Relates to a device.

In general, a device such as a screw organ or a hammer drill that excavates the ground in a ground excavator is usually equipped with a single motor that produces a high horsepower output and a planetary gear reducer that slows down the rotation speed of the motor very slowly. The screw organ was rotated by using the orga drive unit as a power source, and the casing organ was assembled to an attachment member attached to the lower end of the output shaft of the organ drive unit so as to receive the rotational output directly.

Therefore, the upper part of the casing oga is naturally closed. As an example, the invention of Patent Application No. 94-28427, which was filed by the present applicant, was invented so that the screw oga or the hammer drill and the casing oga can also be used. The motor mounted on the OGA drive unit is composed of one, and the upper side of each of the upper side of the skirt tube to which the screw organ or the hammer drill can be assembled and the casing organ can be attached are closed.

Therefore, in the conventional method of embedding a pile using a casing oga, in order to excavate a pile hole as a casing oga and then insert the concrete pile into the casing oga, after disassembling the orga drive unit of the casing oga, the orga drive unit is moved. Under the condition that the upper side of the casing oga is completely open and there are no obstacles, the pile has been buried by lifting the concrete pile using the auxiliary crane and inserting it into the casing o.

However, the conventional method of disassembling the OGA drive unit and embedding the pile in the casing OGA has shown the drawback of delaying the pile installation air due to the following problems.

In other words, because the OGA drive unit itself is a heavy load, it must be moved to the crane lift equipment installed in the crawler traveling device. First, the OGA drive unit is dismantled from the casing Oga that excavates the ground, and then the OGA drive unit is moved upward. Since the upward movement of the casing oil cannot be completely opened at the upper part of the casing oil, the upper part of the dismantled casing oil is completely opened by moving the crawler driving device itself, and the obstacle is removed. Lift the concrete pile vertically to insert the pile into the casing o, then replace the orga drive unit that was disassembled to remove the casing oga from the pile hole by repositioning the orga drive unit. As mentioned earlier, Because the OGA Drive Unit is moved as a crane lift machine, it is not only difficult to accurately move to the recombination position with the casing Ogawa, but also the recombination work is very slow because the crawler drive itself must move. In the case of continuous installation, the work air was delayed considerably.

The present invention eliminates the above drawbacks, and further to excavate the ground with a casing Oga to install the pile, and then immediately insert the concrete pile into the casing Oga without dismantling the OGA drive unit operating the casing Oga It aims to make the file installation work more efficient and faster by providing a method that can be used.As a means to accomplish this purpose, the motor, which is the power source of the OGA Drive Unit, is used as a high horsepower motor. A device configured to divide and mount two motors that can obtain the required total horsepower without a configuration, and to allow the outputs of the two motors to be simultaneously transmitted to one rotating cylinder, and Casing O is attached to the tubular screw formed by round or square pipe As a method of construction, when excavating pile hole, supplying pneumatic pressure with tubular screw to facilitate the soil work, and supplying cement mortar when removing casing oga to install concrete pile firmly and firmly. Invented to provide the present invention will be described in detail below with reference to the accompanying drawings.

The lower two stages are assembled so that the rotational output of the motor is reduced to two stages, which is the same as that used in the conventional OGA drive unit, so a detailed description thereof will be omitted.

The small gears 12a and 12b mounted on the reduction output shafts 11a and 11b are inserted into both sides of the gear box 13 and are installed in engagement with both sides of the ring gear 14. 14 is coupled as a bolt 16 to a rotating cylinder 15 in which rotation is freely installed in the center of the gearbox 13.

The rotating cylinder 15 has an insertion hole 15a through which the concrete pile 8 can be inserted, and a flange 17 is attached to the lower end thereof as a bolt.

An upper flange 19a of the shovel device 18 is coupled to the flange 17 by a bowl, and the fixed outer cylinder 20 and the rotating inner cylinder 21 of the shovel device 18 are upper and lower bearings 22a. (B) -shaped packing 23 interposed therebetween, and the inlets 24a and 24b formed on both sides of the fixed outer cylinder have passages 25a and 25b formed in the rotating inner cylinder. It is configured to communicate at any time, the fixed outer cylinder is in a non-rotating state, while the rotating inner cylinder is in a rotating state for this purpose to form an annular groove in the inner portion of the inlet (24a, 24b) of the fixed outer cylinder, and also in the rotation The annular passage 26 is formed in a contact position between the injection hole and the passage by forming an annular groove in the outer portion of the passages 25a and 25b of the cylinder.

Meanwhile, holes 27a and 27b communicating with passages 25a and 25b are formed in the lower flange 19b attached to the bottom of the inner cylinder 21, and the casing oil 6 is attached. Forming a flange on the upper end of the lower flange (19b) may be assembled in the present invention is shown as an embodiment of the casing oga welded to the lower flange.

On the outer circumference of the casing oga 6, two rows of tubular screws 28a and 28b are formed in a spiral shape, and the tubular screws are formed of circular or square pipes as shown in FIG. 4 (a) (b). Oga head 29 having a plurality of bits (29a) attached to the pneumatic or cement mortar supplied to the inlet by attaching the upper end is connected to the holes (27a, 27b) of the lower flange (19b) to the tubular screw It is discharged to the outer circumferential side of the, and the bottom of the oga head 29 is fitted with an easy-to-remove bit 30 is attached, the double bit 30 is as shown in Figure 5 of the oga head 29 The protrusion 30b is fitted to the oga head in a configuration in which the protrusion 30b is inserted into the groove 29b formed on the inner surface, and the cover bit assembled as described above enters the oga head while being excavated while rotating together during the rotation operation of the oga head. Attached to it, preventing it from becoming The bit 30a is to excavate together with the bit 29a of the oga head. When the concrete pile 8 is inserted into the casing o after the completion of the excavation operation, and the casing o is moved upward, the weight of the concrete pile is increased. It was detached from Ogahead and buried in the pile.

On the other hand, since the casing oga 6 should be able to excavate the pile hole (P) of the depth that can be embedded in the concrete pile (8) to the principle of configuring a relatively long length in accordance with the embodiment of the present invention As well as the casing Oga can be configured in a single body, it can also be configured by assembling in two or more stages.

Referring to the method of inserting the file into the casing Oga and the operation and effects of the device as a member of the present invention as follows.

The organo drive unit 5 is installed with a wire cable 4 squeezed to the top sheave 3 on the top of the reader device 2 of the crawler traveling device 1 as in the prior art, and the organ drive unit 5 is driven to casing. The pile hole P is excavated to the ground by rotating the oga 6, and the casing oga 6 according to the present invention has two tubular screws 28a and 28b formed on its outer periphery. The pneumatic pressure of the compressor (not shown) supplied to the injection holes 24a and 24b of the 18 is supplied by the pneumatic pressure through the passages 25a and 25b to eject the pneumatic pressure from the outer periphery of the orga head 29. Due to the pneumatic ejection of the soil is smoothly moved upwards, the work is carried out quickly, thereby smoothing the excavation work.

After the excavation work of the pile hole P is completed as described above, the concrete pile 8 is inserted into the casing oars 6. In the related art, the casing o is formed by dismantling the orga drive unit 5 from the casing oars. Although the upper side of (6) has been opened, in the present invention, the power source of the OGA drive unit is two motors (9a) (9b), and these casing organs are assembled on both sides of the gearbox (13) by a gear. The concrete pile 8 is to be inserted through the insertion hole 15a of the rotating cylindrical body 15 formed at the center side of the box.
