Description

File construction apparatus capable of simultaneous achievement of hole-boring and vibrating}

One embodiment of the present invention relates to a pile construction device, and more specifically, to enable pile construction by simultaneously performing the drilling operation of the pile hole for inserting the pile and the driving operation for inserting the pile into the pile hole. It is related to a pile construction device that can simultaneously perform drilling and driving work to reduce the time required.

In general, when constructing a reinforced concrete structure or other building, the foundation is buried by driving PHC, steel pipe piles, H-beams, sheet piles, etc. into the ground at regular intervals to strengthen the foundation of the building's ground. As construction is being carried out, the construction of such piles is very important in constructing structures and buildings.

Pile construction methods such as pouring construction method and excavation construction method are used in foundation construction. The pouring construction method involves placing a pile by raising and then dropping a heavy hammer using a hoisting rope installed on the top of a leader installed vertically on a crane, or using compressed air from a compressor to raise and lower the hammer to place the pile. It is a method of pouring and inserting into the ground. However, these construction methods have many limitations in their use due to the problem of generating a large hitting sound and vibration when pouring the top of the pile with a hammer.

Therefore, it can be type installed on the ground in a structure in which multiple sheet piles are connected in a straight line, or can be type installed while connected in a straight line and then turned to a desired angle, or can be type installed to form a circle. , Such sheet piles are mainly pressed into the ground using a noise-free and vibration-free method in road, revetment, port and river construction, such as when constructing concrete buildings, continuous water barriers, and piers for bridges and overpasses. But it is being used a lot.

However, according to this conventional excavation construction method, the drilling work using an auger screw, the lifting of the sheet pile using a leader, and the insertion work of the sheet pile using a vibrator are carried out separately, and are performed alternately and repeatedly, thereby creating one pile.

In one embodiment, the support portion 330 may be coupled to the perforator 200, and the support portion 330 may be raised or lowered along the perforator 200. For example, a casing rail 231 is provided on one side of the casing 230, and the support portion 330 can be slidably coupled to the casing rail 231. In this way, according to one embodiment of the present invention, the support portion 330 can be raised and lowered on the leader 110, and as a result, the pile driver 300 can be raised and lowered even in a state where the boring machine 200 is not lifted.

In one embodiment, the puncher 200 may be rotated using an imaginary straight line parallel to the vertical direction of the leader 110 as a rotation axis. In one embodiment, the rotation axis of the drill 200 may be the same as the rotation axis of the screw 220. In another embodiment, the rotation axis of the puncher 200 may be a virtual straight line parallel to the vertical direction of the leader 110 while passing through a point on the first guide 250. As an example, a virtual straight line parallel to the vertical direction of the leader 110 while passing through the point where the second guide 260 rotates on the first guide 250 illustrated in FIG. 5 may be the rotation axis of the puncher 200. there is.

In this way, the position of the pile driver 300 can be adjusted as the driller 200 rotates, and as a result, the seat pile can be moved without moving the car body or the leader 110 itself while performing the connecting or drilling work of the sheet pile. The position can be adjusted precisely and conveniently.

In one embodiment, while the casing 230 in the drill 200 is long in the vertical direction, the auger 210 or the casing coupling part 215 has a relatively long vertical direction compared to the casing 230. It's short. Therefore, when the casing rail 231 is provided in the casing 230 and the support part 330 is coupled to be able to be raised and lowered along the casing rail 231, the pile driver 300 is raised while the boring machine 200 is stopped. ) can have the largest possible rise and fall range.

You can control it in detail and conveniently.

In one embodiment, support 330 may be coupled to leader 110, and support 330 may rise or fall along leader 110. For example, a leader auxiliary rail 112 is provided on one side of the leader 110, and the support part 330 can be slidably coupled to the leader auxiliary rail 112. As such, according to an embodiment of the present invention, the support portion 330 can be raised and lowered on the leader 110 separately from the drill 200, and as a result, even in a state where the drill 200 is not lifted, the pile driver 300 Elevation becomes possible, and the efficiency of positioning work, such as fitting a sheet pile with another sheet pile, can be improved through the raising and lowering operation of the pile driver 300. At this time, the leader rail 111 on which the drill 200 is coupled to be able to lift and lower may be provided on the other side of the leader 110.

In one embodiment, the pile driver 300 can be rotated, and the coupling relationship between the support portion 330 and the rotation guide 340 has been described above, so redundant description is omitted.

In one embodiment, the auxiliary leader 120 is coupled to the leader 110, and the support portion 330 is coupled to the auxiliary leader 120, so that the support portion 330 can rise or fall along the auxiliary leader 120. . For example, a leader rail 111 is provided on one side of the leader 110, an auxiliary leader 120 is coupled to the other side of the leader 110, and an auxiliary leader rail 121 is provided on one side of the auxiliary leader 120. And, the support portion 330 can be slidably coupled to the auxiliary leader rail 121. As such, according to one embodiment of the present invention, the support portion 330 can be raised and lowered on the auxiliary leader 120 separately from the boring machine 200, and as a result, even in a state where the boring machine 200 is not lifted, the pile driver 300 ) can be raised and lowered, and the efficiency of positioning work, such as fitting a sheet pile with another sheet pile, can be improved through the lifting operation of the pile driver 300. At this time, the leader rail 111 on which the drill 200 is coupled to be able to lift and lower may be provided on the other side of the leader 110.

In one embodiment, the auxiliary leader 120 is rotatably coupled to the leader 110, and as a result, the pile driver 300 can be rotated. At this time, the auxiliary leader 120 may be coupled to the leader 110 so that it can be rotated about an imaginary line parallel to the leader 110 as an axis while passing a point on the leader 110. To this end, the auxiliary leader guide 130 may be intervened between the leader 110 and the auxiliary leader 120.

In one embodiment, the vibration generating unit 320 or the pile fixing unit 310 may be coupled to the support unit 330 to be movable in the horizontal direction. For example, referring to Figures 5 and 6, the position at which the rotation guide 340 is coupled to the support part 330 can be adjusted in the horizontal direction, and further, the rotation guide 340 can slide on the support part 330. can be combined Here, the rotation guide 340 may change its position in the horizontal direction without rotating around a point on the support portion 330. In other words, an embodiment in which the part corresponding to the rotation guide 340 can only move horizontally and not rotate is also possible.

The positional relationship between the support part 330 and the vibration generating part 320 or the support part 330 and the pile fixing part 310 can be applied on a similar principle to other embodiments described above.

Accordingly, when the size of the sheet pile changes or the diameter of the pile hole changes, it is possible to efficiently respond to the change by moving the vibration generating unit 320 or the pile fixing unit 310 in the horizontal direction.

Referring to FIG. 2, in one embodiment, the bit 240 may be formed to have a major axis 241 and a minor axis 242. At this time, when the drill 200 is raised in the first state in which the bit 240 is positioned so that the long axis 241 of the bit 240 faces the pile fixing part 310, the bit 240 is placed on the adjacent casting. When contact is made and the long axis 241 of the bit 240 is raised while the long axis 241 of the bit 240 is not facing the pile fixing part, the bit 240 is implemented in a shape in which the bit 240 does not contact the adjacent casting. It can be. For example, in the case of the bit 240 having an overall rectangular shape, the long axis with the longest length is equal to the diameter (240R) of the rotation range of the bit 240, and as a result, the diameter of the second pile hole 12 and the long axis ( 241) becomes the same length. In the pile construction device capable of simultaneously performing drilling and driving work according to this embodiment, after the pile hole drilling is completed and before raising the driller 200, the long axis of the bit 240 is in the direction of the sheet pile, that is, the pile fixing unit 310. By rotating the bit 240 so that it does not face the direction and then raising the puncher 200, the bit 240 can be prevented from contacting adjacent sheet piles during the raising process of the puncher 200.

The conventional conventional bit 240 was generally made to have an overall circular shape. And, the bit 240 was generally made to have a diameter larger than the diameter of the casing 230. For example, the casing 230 may have a diameter of 457 mm, 508 mm, 560 mm, etc., and for each diameter of the casing 230, a bit 240 having a diameter of 460 mm, 512 mm, 570 mm, etc. may be used in the screw 220. It means that it can be combined with . According to one embodiment of the present invention, the insertion process of the first sheet pile 21 into the first pile hole 11 and the drilling process of the second pile hole 12 proceed simultaneously, using a conventional general circular bit ( When using 240), in the process of raising the perforator 200, a situation may occur in which the bit 240 is caught in the first sheet pile 21 and cannot be raised, or the bit 240 may be raised while damaging the first sheet pile 21. there is. According to one embodiment of the present invention, since the bit 240 is formed to have a major axis 241 and a minor axis 242, it is possible to form a pile hole of sufficient diameter and, while raising the driller 200, adjacent sheet piles There is no situation in which bit 240 cannot be raised due to damage or jamming of adjacent sheet files.

In one embodiment, a guide portion 270 may be provided at the lower portion of the casing 230. At this time, the guide unit 270 may be slidably coupled to an adjacent sheet pile (eg, the first sheet pile 21 in FIG. 3). Meanwhile, the insertion process of the first sheet pile 21 may be performed with one end of the first sheet pile 21 fitted into one end of the basic sheet pile 20. Accordingly, in the process of drilling the second pile hole 12 simultaneously with the insertion of the first sheet pile 21, the insertion direction of the first sheet pile 21 is guided by the basic sheet pile 20, and the casing The downward direction of (230) may be guided by the insertion direction by the first sheet pile (21).

Position it. At this time, the perforator 200 can be positioned at the position where the first pile hole 11 is to be formed. In this process, the process of positioning the driller 200 and the pile driver 300 can be carried out efficiently by rotating the driller 200 or the pile driver 300. In addition, precise position control is possible by horizontally moving the vibration generating unit 320 or the pile fixing unit 310 on the support unit 330.
