Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method of driving steel pipe piles into the ground for constructing foundation piles for structures, particularly in situations where the height of the working space is restricted. This invention relates to an advantageous steel pipe pile driving method.

(Prior art) For example, as shown in Fig. 1, in a situation where an elevated road slab 1 is constructed directly above a river 2 via a bridge pier 3, the age of the seawall 4 in the river 2 is determined. If it becomes necessary to construct a revetment reinforcing structure 5 inside the revetment 4 due to progress of deterioration, the foundation piles 6 that support the revetment reinforcement structure 5 may be used for driving piles that are moored and fixed to the river 2. The construction is carried out using a pile driver on a barge, but the piling work on this barge must be performed within the space below the elevated road slab 1, that is, the height of the work space during piling work is Since the above-mentioned elevated road slab 1 is greatly limited by the presence of the elevated road slab 1, it is not possible to use a pile driver equipped with a long leader.

On the other hand, as described above, the conventional general pile driver used on barges etc. is a leader supported vertically on a crawler crane, as disclosed in Japanese Patent Publication No. 62-34883, etc. The auger machine is equipped with an auger machine that can be raised and lowered, and the auger machine clamps the upper end of a steel pipe pile (casing) that fits around the earth auger, and rotates in the opposite direction to the earth auger while rotating in the axial direction. This is a large, long type of structure that consists of a steel pipe pile (casing) press-fitting means attached to the underside of the auger drive device. Therefore, in such conventional pile driving machines, when the leader is shortened for use at work sites where the height of the pile driving work space is limited as described above, the auger drive device and the steel pipe pile (casing) press-fitting means are shortened. The vertical stroke of the integrated auger machine, which has a long overall length, becomes very short. Naturally, the upper end of the steel pipe pile (casing) can be set in the steel pipe pile (casing) press-fitting means with the auger machine raised to the upper end of the leader. The overall length will also be significantly shorter.

(Problem to be solved by the invention) Therefore, by simply using a conventional pile driver with a short leader, it is possible to perform pile driving work at work sites where the height of the pile driving work space is greatly restricted as described above. In this case, the unit length of the steel pipe pile that can be used becomes extremely short, so in order to drive one steel pipe pile (casing) of the required length, many short steel pipe piles must be successively added and press-fitted. This required a great deal of effort and time, leading to a significant increase in costs.

(Means for Solving the Problems) In order to solve the conventional problems as described above, the present invention has the following features:
A steel pipe pile press-fitting device and an auger drive device are supported on a leader rotatable around a vertical axis so as to be able to move up and down separately by shifting their positions in the circumferential direction of the leader, and the press-fitting device includes:
A steel pipe pile rotation driving ring equipped with a steel pipe pile chuck that clamps the outer peripheral surface of a steel pipe pile that penetrates vertically is provided, and the sheet is attached to the upper end of the leader with this press-fitting device positioned near the lower end of the leader. Insert the steel pipe pile suspended by the hanging cable via the steel pipe pile rotation drive ring, and repeat the press-fitting operation of forcibly lowering the steel pipe pile rotation drive ring while rotating the steel pipe pile rotation drive ring while the steel pipe pile chuck is activated. After pressing the steel pipe pile into the ground and press-fitting the steel pipe pile to a desired position, the next steel pipe pile is lowered as described above and welded to the preceding steel pipe pile, and the press-fitting operation is repeated in the same manner, In the process of using an earth auger, the leader is rotated around the vertical axis, an auger drive device is positioned concentrically above the steel pipe pile in place of the press-fitting device, and the earth is set in the auger drive device. This invention proposes a steel pipe pile driving method characterized in that an auger is rotated and moved up and down through the inside of the steel pipe pile.

(Function of the Invention) The press-fitting device used when press-fitting steel pipe piles is separated from the auger drive device, so the overall length is shorter than that of a conventional auger machine in which both are connected vertically. Therefore, the length of the steel pipe pile that can be used when the working space is limited by the distance from the press-in device to the top end of the leader when the press-in device is located near the bottom end of the leader, that is, the height to the top of the leader. The length is longer than the length of a steel pipe pile that can be set in a conventional auger machine with a long overall length when the auger machine is located at the upper end of the leader.

However, as mentioned above, a press-in device is used to press-fit the required number of steel pipe piles into the ground, but if it becomes difficult to press-fit the steel pipe piles by simply pushing them down while rotating, The press-fitting operation is interrupted, and the press-fitting device is raised and removed above the upper end of the steel pipe pile, and the leader is rotated as described above to position the auger drive device at a concentric position above the steel pipe pile. Then, using the space between the auger drive device located at the upper end of the leader and the steel pipe pile, the earth auger is set in the auger drive device, and the earth auger is lowered while being rotated, and the steel pipe that was previously press-fitted is The steel pipe pile press-fit area below the lower end of the pile is excavated, and in this case, the earth auger is used while increasing its total length by sequentially adding shaft rods each time the auger drive device reaches its lowering limit.

When excavation to the required depth is completed, the earth auger and auger drive device are separated, the leader is rotated to return the press-in device to the concentric position above the steel pipe pile, and the press-in device is used again to remove the steel pipe pile. Perform additional press-fitting work. Once the steel pipe pile has been press-fitted to the required depth, the press-in device and auger drive device are replaced again, the earth auger waiting inside the steel pipe pile is connected to the auger drive device, and the earth auger is reversed. The foundation pile can be constructed by a conventionally known method such as pouring mortar while pulling out the pile.

In addition, it is also possible to drain the earth and sand inside the steel pipe pile that has been press-fitted to the required depth and construct a reinforced concrete pile using reinforcing steel and concrete inside the steel pipe pile.

In either method, it is also possible to use the press-fitted steel pipe pile as a formwork (casing) for foundation pile construction, and to pull it out using the press-in device after use.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

It is pivotally connected to the upper end of the crawler crane 9 by a support shaft 16, and a cylinder unit 17 for inverting/erecting operation is interposed between the crawler crane 9 and the crawler crane 9. The lower end of the leader upper half 12, which has been switched from the lying position to the standing position by the cylinder unit 17, is flange-bonded to the upper end of the leader lower half 11 with bolts and nuts.

As shown in FIGS. 3, 4, and 6, the leader 10 includes a steel pipe pile press-fitting device 18 and an auger drive device 19.
and are supported so as to be movable up and down separately via guide rails 20 and 21 with a phase shift of 90 degrees in the leader circumferential direction. Further, at the upper end of the leader 10 (the upper end of the leader upper half section 12), as shown in FIGS.
and an arm 24 equipped with a guide sheave 26 that guides the lifting cable 25 of the auger drive device 19.

A guide sheave 2 for guiding the suspension rope 28 is disposed above the 27.
An arm 30 with 9 is rotatably supported about the vertical axis of the leader 10.

As described above, the leader 10 is rotatable about the vertical axis with respect to the pair of upper and lower support members 13.15. As a means for rotating the leader 10, for example, as shown in FIG. , an arm 31 protruding from the leader 10 (leader lower half 11) and a crawler crane 9

As shown in FIG. 8 and FIG.
As shown in FIG.
The press-fit device main body 40 is suspended via a pair of left and right push-down cylinder units 39, and the press-fit device main body 40 has a steel pipe pile rotation drive supported so as to be able to rotate only around a vertical axis. a ring 41, a pair of left and right drive units 42 that rotationally drive the ring 41, and a steel pipe pile chuck 4 connected to the lower side of the ring 41.
3 is provided. The drive unit 42 drives the steel pipe pile rotation drive ring 41 to a motor 47 via a large gear 44 concentrically connected to the outer periphery of the ring 41, a small gear 45 meshing with the small gear 45, and a reducer 46. The steel pipe pile chuck 43 is driven by a plurality of projection chuck pieces 49 connected via links 48 at positions equally spaced in the circumferential direction of the ring 41, and these plurality of paddle-shaped chuck pieces 49. an elevating ring 51 that rotatably supports a ring-shaped cam 50 externally fitted on the chuck piece 49 at a position concentric with the ring 41; a plurality of elevating guides 52 in the circumferential direction that guide the elevating ring 51 so as to be able to only move up and down; Elevating ring 51
It is composed of a plurality of cylinder units 53 in the circumferential direction that drive the cylinder up and down. Therefore, each cylinder unit 53
By pulling up the elevating ring 51, each chuck piece 49 moves close to the rotation axis of the steel pipe pile rotation drive ring 41 by the ring-shaped cam 50 that rises together with the elevating ring 51, and moves inside this ring 41. It is possible to clamp the outer peripheral surface of the penetrating steel pipe pile in a self-centering manner. On the other hand, when the steel pipe pile rotation drive ring 41 rotates, the link 48, the chuck piece 49, and the ring-shaped cam 50 rotate together, so the steel pipe pile rotation drive ring 41 is rotationally driven by the drive unit 42. Then, the steel pipe piles clamped by the steel pipe pile chuck 43 can be rotationally driven as one unit.

On the upper side of the press-fitting device main body 40, a steel pipe pile hanging guide 54 having a substantially U-shaped cross section and an open front side is provided to protrude along the inner circumferential surface of the steel pipe pile rotation drive ring 41. There is. Of course, an arcuate cutout 55 is also formed on the front surface of the elevating body 38 so as to follow the inner circumferential surface of the steel pipe pile hanging guide 54.

As shown in FIGS. 10 and 11, there are a plurality of guide sheaves pivotally supported on the base 36 between the elevating body 38 of the steel pipe pile press-in device 18 and the lower end base 36 of the leader 10. 35 and a plurality of guide sheaves 56 that are pivotally supported by the elevating body 38, the press-fitting device pull cable 57 is attached to the base 3.
It is wound and stretched from the 6th side.

To explain the steel pipe pile driving method of the present invention using the pile driver configured as described above, as shown in FIG. On the barge 7, the leader upper half 12 of the crawler crane 9 is erected and connected to the leader lower half 11, and the leader 10 is assembled. In other words, when towing the barge 7, the upper half 12 of the leader 10 can be laid down to lower the overall height, as shown in FIG. 1! , 13, it is not necessary to remove the entire leader 10 from the crawler crane 9.

Next, as shown in FIG. 3, the steel pipe pile is suspended with the steel pipe pile press-in device 18 at the lower limit position, and when the elevated road slab 1 shown in FIG. ) and it is not possible to secure a working space above the upper end of the leader 10, use a steel pipe pile that is appropriately shorter than the distance between the main body 40 of the main body 18 and the arm 30 at the lowering limit position. 59 is used, and the steel pipe pile 59 is suspended by a hanging rope 28 that is passed around the guide sheep 29 of the arm 30. However, the suspension rope 28 is wound up with a winch on the side of the crawler crane 9 and attached to the steel pipe pile 5.
9 is lifted directly above the main device 18. At this time, there is no need to lift the lower end of the steel pipe pile 59 to a position above the upper end of the steel pipe pile lifting guide 54 of the press-in device 18. As shown by the virtual lines in Figure 10,
When the lower end of the steel pipe pile 59 is slightly higher than the press-fitting device main body 40, enter the steel pipe pile hanging guide 54 laterally from the front open part, and attach the lower end of the steel pipe pile 59 to the inner peripheral surface of the guide 54. The steel pipe pile 59 can be positioned directly above the steel pipe pile rotation drive ring 41 with their peripheral surfaces in contact with each other (see FIG. 12).

On the other hand, since the steel pipe pile press-fitting device 18 is positioned directly above the pile driving position, once the steel pipe pile 59 has been lifted as described above, the hanging cable 28 is let out to lower the steel pipe pile 59, and the steel pipe pile It passes through the rotary drive ring 41 and the steel pipe pile chuck 43 and is erected vertically into the ground by its own weight (see the imaginary line in Figure 12).

Next, the steel pipe pile 59 is press-fitted into the ground using the press-fitting device 18, and the method is as follows. That is, the lifting cable 22 suspending the press-in device 18 is operated by the winch of nine crawler cranes, and after the press-in device 18 is raised a suitable distance, the steel pipe pile chuck 43 is activated as shown in FIG. With the steel pipe pile 59 clamped to the press-fitting device main body 40, the press-fitting device main body 40 is pushed down against the elevating body 38 by the pushing-down cylinder unit 39.

At this time, the press-fitting device pull cable 57 is pulled by the winch of the nine crawler cranes and is in a tension state, preventing the upward movement of the elevating body 38, so that the press-fitting device main body 40 is is forcibly pushed down together with the steel pipe pile 59. On the other hand, by operating the motor 47 of the drive unit 42 to rotationally drive the steel pipe pile rotation drive ring 41, the steel pipe pile 59 clamped by each chuck piece 49 of the steel pipe pile chuck 43 is driven to rotate the steel pipe pile. It rotates around the vertical axis together with the ring 41.

As described above, while the steel pipe pile 59 is rotated by the drive unit 42, the steel pipe pile rotation driving ring 41, and the steel pipe pile chuck 43, the press-fitting device main body 40 is pushed down by the push-down cylinder unit 39, thereby pushing the steel pipe pile 59 into the ground. It is possible to press-fit vertically into the interior (although it is possible to do so, the upward reaction force is applied to the front end of the crawler crane 9 via the lifting body 38, the press-fitting device pull cable 57, the base 36, and the leader 10). The weight of the crawler crane 9 stops the support. However, if the reaction force during press-fitting of the steel pipe pile is large and the front end of the crawler crane 9 tends to lift up, the
As is well known in Publication No. 883, etc., the lower end of the leader (base 36
) can be taken to be anchored to the barge 7.

When the press-fitting for the stroke of the push-down cylinder unit 39 is completed, the steel pipe pile clamp by the steel pipe pile chuck 43 is released (the lifting ring 51 is pushed down by the cylinder unit 53), and then the push-down cylinder unit 39 is contracted, and the press-fit device The main body 40 is attached to a steel pipe pile 5
9 and returned to the initial position close to the elevating body 38, the steel pipe pile 59 is rotated and press-fitted again in the manner described above. The steel pipe pile 59 can be press-fitted into the ground to a depth where its upper end reaches the welding connection work level with the next steel pipe pile.

When the press-fitting of the first steel pipe pile 59, that is, the lower end steel pipe pile 59A is completed, as shown in FIGS. 2 and 13, the next intermediate steel pipe pile 59B is suspended directly above the lower end steel pipe pile 59A in the manner described above. It's crowded. Then, the abutting ends of the image adjustment tubes 59A and 59B are connected and integrated by welding. After this, by performing the steel pipe anti-rotation press-fitting operation by the press-fitting device 18 in the same manner as described above, the steel pipe pile 59 whose total length has been increased due to addition, that is, the lower end steel pipe pile 59A and the intermediate steel pipe pile 59B are press-fitted into the ground as one unit. You can.

As described above, a plurality of steel pipe piles 59 are press-fitted in sequence, but if one intermediate steel pipe pile 59B
If the lower end steel pipe pile 59A reaches the hard ground when press-fitting with additional parts, and it becomes difficult to press-fit any further, the steel pipe pile clamp by the steel pipe pile chunk 43 is released, and the entire press-in device 18 is moved to the lifting cable 22. After lifting the leader 10 upwardly from the upper end of the intermediate steel pipe pile 59B, the leader 10 is rotated 90 degrees around the vertical axis by the cylinder unit 32 shown in FIG. Instead of the steel pipe pile press-in device 18, an auger drive device 19 is positioned at the pile driving work position. Incidentally, in FIG. 4, illustration of the press-fitting device 18 is omitted. A telescopic earth auger 60 is set in the auger drive device 19 in a contracted state while being lifted up to the upper end position of the leader 10. This auger drive device! During work, the earth auger 60 can be attached to the earth auger 19 using the hanging rope 28 used when suspending the steel pipe piles 59A and 59B. In this case, since the arm 30 is rotatable around an axis perpendicular to the leader 10, the tip of the arm 30 can be positioned directly above the auger drive device 19 even when the leader 10 is rotated 90 degrees. I can do it.

As described above, the earth auger 6 is connected to the auger drive device 19.
0 is set in the contracted state, the earth auger 60 is extended, and while rotating the earth auger 60 in the excavation direction, the lifting cable 25 is let out from the winch of the crawler crane 9, and the auger drive device 1
9, and the steel pipe piles 59B, 59 are lowered by the earth auger 60 until the auger drive device 19 reaches the lowering limit position.
Excavate inside A. When the auger drive device 19 reaches the lower limit position, the auger drive device 19 and the earth auger 60
After separating the auger drive device 19 from the lifting cable 25 to the upper limit position, and connecting the auger drive device 19 and the earth auger 60 by the intermediate rod, the earth auger 60 is moved again as described above. Excavate (see Figure 14).

As shown in FIG. 15, once the earth auger 60, which is successively extended by the intermediate shaft rod, has excavated to the level of the lower end of the foundation pile, the earth auger 60 and the auger drive device 19 are separated, and the auger drive device 19 is moved up and down. After being raised by the rope 25, the leader 10 is again rotated 90 degrees in the opposite direction, and the steel pipe pile press-in device 18 is returned to the pile driving position in place of the auger drive device 19. After that, the upper end steel pipe pile 59C is suspended in the manner described above, and the middle steel pipe pile 59C is
After the abutting ends with 9B are connected and integrated by welding, the lower end steel pipe pile 59A to the upper end steel pipe pile 59C are rotated and press-fitted together by the press-fitting device 18.

Once the upper end steel pipe pile 59C has been press-fitted to a predetermined level, as shown in FIG. With the lower end and the upper end of the upper end steel pipe pile 59C tied together, the press-fitting device 18 connects the upper end steel pipe pile 59A to the upper end steel pipe pile 5 through the pipe 61.
Press-fit the entire 9G while rotating it.

When the upper end of the upper end steel pipe pile 59G reaches the ground breaking depth (
When the lower end of the upper end steel pipe pile 59A reaches the level of the lower end of the foundation pile, the press-in device 18 lifts and removes the roller 1, and then the leader 10 is rotated 90 degrees again and the auger drive device 19 is moved to the pile driving work position. and steel pipe piles 59A~
Connect the upper end of the earth auger 60 remaining at ss+c C to the auger drive device 19. Then, as shown in FIG. 17, the earth auger 6 is driven by the auger drive device 19.
The earth auger 60 is moved to the steel pipe piles 59A to 59C by upward movement of the auger drive device 19 while rotating the earth auger 60 in the opposite direction.
It is pulled out from the inside, but at this time the earth auger 6
Pour mortar from the tip through the shaft rod of 0, and attach it to the steel pipe pile 5.

The foundation pile 6 shown in the figure can be constructed.

Also, the earth auger 60 or this earth auger 6
The earth and sand in the steel pipe piles 59A to 59C are discharged using an earth removal grab attached to the auger drive device 19 instead of the auger drive device 19, and reinforcing bar cages are inserted into the steel pipe piles 59A to 59C, and concrete is poured to form the foundation pile. It is also possible to build 6. In this case, the steel pipe piles 59A to 59C are used as caning for the concrete formwork, and the press-in device 1
8 can also be used to pull out the steel pipe piles 59A to 59C.

In the above embodiment, a guide 54 for suspending the steel pipe pile 59 is provided in the steel pipe pile rotation drive ring 41 of the steel pipe pile press-in device 18, but this steel pipe anti-suspension guide 54 is essential for the construction method of the present invention. It's not a thing, but it can be omitted. or,
In the above example, the method of the present invention is used for piling work on a barge associated with river bank reinforcement work, but it is also applicable to steel pipe pile driving work at other construction sites with upper air restrictions. You can also use invented construction methods.

(Effects of the Invention) As described above, according to the method of the present invention, compared to the conventional method, when driving steel pipe piles at a site where the height of the pile driving work space is limited by existing structures, etc. Therefore, the length of steel pipe piles that can be used is significantly increased, and therefore, the number of additional steel pipe piles required to construct one foundation pile can be reduced. Moreover, since the leader can be rotated to selectively use the steel pipe pile press-in device and the auger drive device, compared to the case where the earth auger has to be used with a completely separate piling machine, Switching between the steel pipe pile press-in process and the earth auger use process can be performed efficiently.

Therefore, as mentioned above, the labor and time required for the entire pile driving work at the site where the height of the pile driving work space is limited by existing structures etc. can be significantly reduced, and the cost of building foundation piles can be lowered. .
