Description

Hitting machine to drive sheet pile deeply using auger}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sheet pile auger cab which types a cast steel sheet pile into a noiseless and vibrationless type.

In general, when excavating the ground in civil engineering or construction work, first put H-beams on the ground to be excavated at regular intervals, and then install earth-to-earth earth walls between two H-beams facing each other while excavating the ground. Since the existing excavated strata are prevented from collapsing, the construction method itself causes various pollutions such as noise pollution and vibration pollution when H-beams are typed on the ground. Is being regulated.

Therefore, in recent years, the noise regulation method and the vibration regulation method have been enacted in accordance with the Pollution Countermeasures Act, which defines various pollutions such as air pollution, water pollution, noise, vibration, and so on. SHEET PILE (Steel Sheet Pile) is being developed.

The sheet pile is made of main steel and its cross section is generally C-shaped and has open trapezoidal trapezoidal shape that is open to the outside of both ends. It has a structure that can be combined. Therefore, a plurality of sheet piles are connected in a straight line type installed on the ground or connected in a straight line type can be installed in the direction of the desired angle, or the type can be installed to form a circular shape In addition, such sheet piles are frequently used to press into the ground by a noiseless and vibration-free method, such as when constructing a concrete building, when constructing a continuous wall of water barrier, and when constructing a bridge such as a bridge or an overpass.

In the prior art, the above-described method for installing the sheet pile as a noiseless and non-vibration type has been developed and used. Among them, there is a method using an auger driver unit and a hydraulic cylinder. The soil piles are mechanically disturbed and excavated, and the pile piles are driven underground with the excavation operation of the auger screw rods in such a way that the pressure input of the hydraulic cylinder installed under the leader is transferred to the sheet piles. In the case of weak adhesive force such as sand, the sheet pile can be press-fitted by the weight of the auger driver unit holding the sheet pile alone, while the soil of the ground is very strong or irregularly large and small rocks are irregular. If you are interspersed, hold the sheet pile The weight of the unit alone prevents the sheet pile from easily penetrating clay soil or rock.In this way, the auger driver unit operates the hydraulic cylinder installed under the reader when the sheet pile cannot penetrate the soil. By increasing the pressure input of the seat pile, the sheet pile is forcibly driven.In this case, the pressure input of the hydraulic cylinder is limited, so when the sheet file cannot be driven by the pressure of the hydraulic cylinder, the sheet pile is press-fitted. It is not possible to proceed anymore, or the wire wound on the winch drum can be applied to press the sheet pile, but there is also a limit to the sheet pile with the wire, so the adhesive force of the ground is strong so that the sheet pile does not get stuck. Or the pile pile is stuck to the rock and can no longer be pressed If you do, you will no longer be able to press the sheet pile.

The present invention was created to solve the problems in the prior art of pressing the sheet pile using the auger driver unit as described above, and as a means for installing a hammer hammer between the auger driver unit and a rotating device installed below it The ground itself has strong adhesive force by allowing the hammer to lift and move repeatedly while exerting and dismantling the ground by the auger head and the auger screw rod, and repeatedly applying force to the sheet pile.

A feature of the present invention is a heavy hammer striking hammer (8) which is installed between the auger driver unit (1) and the rotary device (2) to apply a force to the seat pile (6) while falling naturally to its own weight. ) Is installed. (See Figs. 3, 4 and 8, 9)

As a configuration for this, a sliding hollow pillar 81 and the sliding hollow pillar 81 penetrate the center of the upper surface of the rotating device 2 while allowing the rotation operation of the auger connecting rod 41 penetrating the center thereof. In one state, the noise preventing member 82 is fixedly installed on the upper surface of the rotating device 2, and the heavy hammer striking hammer 8 rides on the sliding hollow column 81 on the upper side of the noise preventing member 82. It is installed so as to operate up and down, and the hitting hammer 8 is configured to be able to apply force while naturally falling by its own weight by the hammer elevating device 9.

The noise preventing member 81 fixed to the upper surface of the rotating device 2 is made of wood that is capable of reducing the noise and the vibration of the impact while the impact of the hammer (8) is transmitted to the seat pile (6) or It is preferable to use a rubber material, and it is preferable that the hammer hammer 8 uses a heavy metal material.

The hammer elevating device 9 for elevating and operating the hitting hammer 8 uses a lifting wire 9a and a pneumatic cylinder 9b, which are first lifted as shown in FIGS. 3 and 4. Referring to the hammer lift apparatus 9 using the wire 9a, a pair of hammer side pulleys 91 are rotatably installed on both sides of the upper end of the hammer 8, and the lower end of the auger driver unit 1 is provided. The auger side pulley 92 is rotatably installed on both sides of the bracket 16 protruding toward the front side, and a plurality of lifting guide pulleys 93 are rotatably installed on one front side of the auger driver unit 1 in the vertical direction. Then, the lead ends of the elevating wire 9a drawn out from the winch device (not shown) installed outside are delivered to the elevating guide pulley 93 on the upper side and the lower side, and then passed through one side of the striking hammer 8 ( The hammer side pulley 91 installed on the right side in the drawing While rolling, it is wound on the auger pulley 92 installed thereon, and then the auger pulley 92 on the other side (left side in the drawing) is turned around and wound on the hammer pulley 91 on the lower side thereof, and then pulled out. The end of the stage is tied to the lower end of the auger driver unit 1 (left side in the drawing) or it is structured to fix by welding. Winch installed on the outside of the hoisting wire 9a addressed to each pulley as described above When the device is operated and pulled, the hammer is moved upward by the pulling operation. The hammer is lifted to a predetermined height, and then the lifting wire 9a that is pulled out is momentarily released. When hitting the hammer (8) is a natural fall to its own weight while hitting the noise preventing member 82, the impact force applied to the noise preventing member 82 is configured to be transmitted to the seat pile (6).

And the hammer lifting device 9 using the pneumatic cylinder (9b) as shown in the embodiment shown in Figures 8 and 9, two pneumatic cylinders (9b) are installed vertically on both sides of the rotary device (2) The cylinder body 95 of the pneumatic cylinder 9b has its lower end penetrating the upper surface of the rotary device 2 and supported at the bottom thereof, and the front end of the piston rod 96 has both upper ends of the hitting hammer 8.

The force applied thereto is transmitted to the seat pile 6 Will.

In each embodiment of the hammer lifting device 9 described above, the striking pressure of the striking hammer 8 is configured to be adjusted as the hydraulic cylinder 3. That is, in the case where the piston rod 32 of the hydraulic cylinder 3 is fully immersed in operation, the height at which the striking hammer 8 can be raised becomes the shortest and the striking pressure is the weakest. In the case of fully emergent operation, the height capable of raising the hammer 8 is longest, and the impact pressure is the strongest. Therefore, the striking pressure of the striking hammer 8 can be adjusted as the hydraulic cylinder 3.

The operation of press-fitting the sheet pile with the present invention configured as described above will be described.

1A to 1E show the auger screw rod 4 and the casing rod 7 after the seat pile 6 is installed in the casing rod 7, the process of typing the sheet pile into the ground, and the type of the sheet pile are completed. As a figure showing a process of pulling out from the ground, a process of first installing the sheet pile 6 to the casing rod 7 will be described.

The sheet pile 6 binds one end of the pile wire 63 to the hole 62 drilled on one side of the upper end as shown in FIG. 2, and then guides the pile wire 63 to the guide pulley 54 of the clamping device 5. When the wire 63 for the pile is pulled by using external power in the state of hanging), the sheet pile 6 is vertically erected as shown in FIG. 1A, and the sheet pile 6 is thus casing. In order to attach to the rod 7, the stopper 61 welded to both bottom inner corner portions of the sheet pile 6 is positioned under the locking pin 71 at the bottom of the casing rod 7, while the sheet pile ( The upper end of 6) is located under the clamping space 53 of the clamping device 5, in which the piston rod of the clamping hydraulic cylinder 51 appears and operates so that the clamp 52 rotates counterclockwise in the drawing. By doing so, the cranking space 53 is wide open.

Pulling the file wire 63 in a state in which the sheet pile 6 is close to the casing rod 7 as described above, the sheet pile 6 is moved upwards, and thus the lower inner side of the sheet pile 6 The stopper 61 welded to the pin is pinched by the locking pin 71 and the upper end of the seat pile 6 is inserted into the clamping space 53. Then, the piston rod of the clamping hydraulic cylinder 51 is immersed. When the clamp 52 is rotated in the clockwise direction on the drawing, the top of the sheet pile 6 is firmly queried. Thus, the stopper 61 at the bottom of the sheet pile 6 is caught by the locking pin 71. When the upper end is firmly held by the clamp 52, the installation work of the sheet pile 6 is completed, and the pile wire 63 is dismantled.

Next, FIG. 1B shows a trust sheave 13 installed at the side of the auger driver unit 1 and a guide sheave 14 installed at the bottom of the leader (not shown) after completing the installation of the seat pile 6. The drawing showing the connection of the traction wire 15, the traction wire 15 connected to the thrust sheave 13 and the guide sheave 14 as described above, the traction end 15a is operated by external power It is connected to a winch device (not shown), the end 15b of which is fixed to a reader or crawler traveling device (not shown).

1C and 1D show that the sheet pile 6 is press-fitted while driving the auger driver unit 1 to excavate the ground with the auger head 42, and the press-fit of the sheet pile 6 is shown. In order to start the operation, first make the upper end of the safety hole 33 formed in the connecting member 33 attached to the tip of the piston rod 32 of the hydraulic cylinder 3 to hold the safety pin 22. The excavation work of the ground is carried out by the auger head unit 42 by driving the auger driver unit 1. When the ground excavation work is performed in this way, the hanger wire connected to the top sheave 12 on the upper part of the auger driver unit 1. The auger driver unit 1 is pulled by the pulling force of the towing wire 15 together with its own weight so that an operation of pulling the towing end 15a of the towing wire 15 together with the action of releasing the pressure occurs simultaneously. Lowering pressure The auger head 42 acts on the giant head 42 to excavate the ground, and the auger screw rod 4 drills at a predetermined interval on one side of the casing rod 7 while moving up the excavated soil. The ground layer through which the auger head 42 is dug into the ground through the earth hole 72 is in a state in which the adhesive force is weakened as the excavated soil is discharged to the ground, so that the sheet pile 6 is the auger driver unit 1. The operation of being pressed into the ground together with the auger head 42 by the pulling force of the self-weight and the pulling wire 15 is to proceed smoothly.

By the way, when the ground layer is weak adhesive force, such as sand, but not only the ground excavation operation of the auger head 42 but also the press-in operation of the sheet pile 6 can proceed smoothly, but the ground is a clay ground having a very strong adhesive force or In the case of the ground where large and small rocks such as gravel are scattered in the strata, the indentation operation of the sheet pile 6 proceeds smoothly only by the weight of the auger driver unit 1 and the pulling force of the towing wire 15. Will not be. One of the reasons is that when the gravel is located at the bottom of the sheet pile 6, the sheet pile 6 must break the gravel so that the press-in operation can proceed. The self-weight of the auger driver unit 1 and the towing wire 15 are This is because the pulling force of the sheet pile (6) can not give a shock that can break the gravel hanging on the bottom, or when the sheet pile (6) is caught by the gravel and the indentation operation is not made smoothly traction wire (15) ), Even if the pulling force of the auger driver unit 1 is increased, the press-fitting operation of the sheet pile 6 does not occur easily unless the gravel is broken.

Therefore, in the present invention, even if the ground is composed of clay with strong adhesion or small rocks such as gravel scattered irregularly in the ground, the sheet pile 6 can be smoothly press-fitted. .

That is, the hammer elevating device 9 carries the hammer of the heavy body provided between the auger driver unit 1 and the rotating device 2 from the time when the work to press-fit the sheet pile 6 to completion is completed. And then the hammer lifting device 9 repeatedly performs the operation of releasing the hitting hammer 8. Thus, the hammer lifting device 9 raises the hitting hammer 8 of the weight by a predetermined height. After lifting up and hitting the hammer (8) to fall naturally hitting hammer (8) hits the noise prevention member 82 with its own weight while falling naturally with a potential energy, so hitting hammer (8 When hitting the noise preventing member 82, the noise preventing member 82 and the rotating device 2 is instantaneously lowered by the impact of the impact, so that the flange 25 of the rotating device (2) A casing rod (7) connected to and installed on the clamping device (5) assembled in the The seat pile 6 is instantaneously descended together with the rotary device 2, and the seat pile 6 descending at this moment has a fairly high speed as it receives the instantaneous striking pressure of the striking hammer 8 as it is. At the same time, it is press-fitted at a strong falling pressure.

Therefore, the sheet pile (6) is a case of the strata in which the large-sized rocks such as gravel are scattered irregularly as well as the press-fitting operation of the clay layer having strong adhesive force is smoothly hung on the bottom of the sheet pile (6). When present, the rocks are broken or pushed sideways by the instantaneous strong striking pressure of the seat pile 6, so that the seat pile 6 is as deep as the striking pressure of the striking hammer 8 is applied. Since the hitting operation of such a hammer (8) is repeatedly made while the orga head 42 proceeds with the excavation operation, the sheet pile 6 is the orga head 42 for the excavation operation. It is pressed together with the ground.

On the other hand, the hydraulic cylinder (3) supporting the rotating device (2) as described above before the impact hammer (8) falls naturally to hit the noise prevention member 82 as described above is the piston rod 32 The upper end of the safety hole 34 formed in the connecting member 33 at the tip is pressing the safety pin 22 penetrating the bracket 21. Therefore, an empty space is formed between the safety pin 22 and the lower end of the safety hole 34, and the empty space is the hydraulic cylinder 3 and the auger driver unit 1 during the striking operation of the hammer. Is a safety distance that allows only the rotary device 2 to descend without descending.

That is, the safety distance of the empty space formed between the safety pin 22 and the lower end of the safety hole 34 is the sheet pile by one blow operation in which the hammer (8) moves up to a predetermined height and then falls naturally. 6) is set in advance so as to be the maximum distance that can be pressed into the ground, and the auger driver unit 1 itself is also lowered as much as the hitting hammer 8 presses the seat pile 6 by one hitting operation. Therefore, the hydraulic cylinder 3 and the connecting member 33 at the tip of the piston rod 32 are also lowered accordingly, and thus the connecting member 8 is moved up again while the striking hammer 8 moves again to perform the striking operation again. (33) is inserted into the bracket 21 again so that the upper portion of the safety hole (34) is pressing the safety pin 22, so that the hitting hammer (8) while hitting the continuous and repeated hitting operation Hammer (8 The inertia of) is not applied to the auger driver unit 1 and the hydraulic cylinder 3 but to the rotary device 2, the clamping device 5, the casing rod 7 and the seat pile 6.

In addition, each of the auger connection rod 41, the auger screw rod 4, and the auger head 42, which are connected to the output shaft 11 of the auger driver unit 1 in multiple phases, has a hammer hammer 8, a noise collector ( 82), the rotary device 2, the clamp device 5 and the casing rod (7) is rotatably inserted.

Therefore, the auger connection rod 41, the auger screw rod 4, and the auger head 42 are normally ground excavated while the impact operation of the hammer 8 is repeatedly performed without being impacted. It will perform the operation.

As described above, the operation of excavating and discharging the ground by driving the auger driver unit 1 and the operation of pressing the single hammer pile 8 into the sheet pile 6 by repeated strike operation are completed. 6) In order to press-fit by extending, the auger screw rod 4 and the casing rod 7 which are separately prepared are assembled and extended, while the sheet pile 6 is similar to the example shown in FIGS. 1A and 1B described above. As shown in FIG. 1C and FIG. 1D, the sheet pile 6 is installed on the newly installed casing rod, and then the upper end of the sheet pile pressed into the ground and the lower portion of the newly installed sheet pile are welded. 6) is press-fitted.

Next, FIG. 1E shows the auger driver unit 1 moving up after the pressing operation of the seat pile 6 is completed. In this case, the clamp hydraulic cylinder 51 of the clamp device 5 is operated. When the clamp 52 releases the upper end of the seat pile 6, and then lifts the auger driver unit 1 while releasing the towing end 15a of the towing wire 15, the casing rod 7 Since the lower locking pin 71 is pulled out of the stopper 61 of the sheet pile 6, only the casing rod 7, the auger screw rod 4, and the auger head 42 can be removed from the ground.

When the press-fitting operation of the sheet pile 6 is completed by the above-described operation, and when a new sheet pile is to be pressed adjacent to the press-fitted sheet pile 6, as shown in FIGS. 11A and 11B, the sheet piles adjacent to each other ( 6) are symmetrical with each other and the two ends are pressed together in a state in which they are bound together, the operation so that the adjacent seat piles (6) to be symmetrical is the worm gear of the hydraulic motor installed in the rotating device (2) It consists of the rotation drive of 24 (refer FIG. 10).

That is, when the seat pile 6 is fixedly installed on the casing rod 7 and then the worm gear 24 of the hydraulic motor mounted on one side of the upper surface of the rotating device 2 is rotated, the turning gear 23 engaged with the seat pile 6 is engaged. The rotating device 2 itself is stationary and the turning gear 23 and the flange 25 are rotated so that the clamping device 5 and the casing rod 7 assembled to the flange 25 are rotated. ) Is rotated together with the turning gear 23, and accordingly the seat pile 6 is also rotated together, so that the sheet pile 6 to be newly pressed is symmetrically coupled to the seat pile previously pressed in a symmetrical state. The sheet pile 6 can be press-fitted in a continuous form as well as continuously connected in a straight line as shown in FIGS. 12A and 12B. Will be.
