(1) Jitsuko Sho 31-12946 This technology relates to a pile for civil engineering work, using a pipe material as a pile, and using a pipe at the tip of the pipe (in the specification, referred to as a cone, it is not a cone or a drill. It is a pipe material pile with a screw thread.) It is built by rotating the top of this pile, but since the cone itself is a screw thread, it is never dug at the depth to obtain the bearing capacity of the pile. What is not done is obvious (the drill excavates due to its structure, but the screw fertilizer does not excavate). Further, the present invention relates to a shaped steel pile, whereas in JP-B 31-12946 there is a difference in that it is a pipe pile. (2) JP-B-52-28285 This invention is essentially a method of burying a water jet pipe in a pile wall and injecting water from the pipe to dig the built-in ground. is there. In this invention, it is impossible to build a steel pile. (3) JP-B-54-75101 This invention relates to a sheet pile driving machine of a type in which a sheet pile insertion hole is previously excavated by an asuger screw and the sheet pile is press-fitted therein. The present invention relates to an improvement of a reaction force receiving mechanism at the time of press fitting and a structure of a lead mast. With this method, it is possible to press fit the sheet pile, but it is not possible to rotationally mount it, and of course it is not possible to rotationally mount the shape steel. (4) JP-B-55-2490 The present invention continuously rotates or repeatedly rotates a foundation pile such as a steel pile and jets high-pressure water from the lower end of the pile.
The present invention relates to a pile driving device for press-fitting a pile without vibration and noise. That is, this method is a method of building the shape steel (H steel), but if the H steel itself is built while rotating, it is built up by the ground built up (apart from special soft ground). The steel is twisted to weaken the strength of the pile. In addition to the extremely small tip supporting force of the pile, the present invention employs means for injecting high-pressure water from the lower end of the pile. Therefore, there is a drawback that the support ground of the pile is weakened, the bearing capacity of the pile is further reduced, and the pile sinks. (5) Japanese Patent Publication No. 62-20334 This invention uses a drive angle shaft after a drive angle shaft having an excavation cone is fitted inside a cylinder having spiral blades on the outer periphery and the pile built-in ground is excavated. Drive the concrete for pile building foundation, then pull out the drive square shaft together with the tip cone, build a ready-made concrete pile in the cylinder, and then rotate the cylinder in the reverse direction to remove the periphery of the concrete pile. It is a method of pulling this out and installing a pile while consolidating. According to this method, it is not possible to erected a shaped steel having a structure having a supporting force at its tip while rotating it. (6) Japanese Patent Publication No. 62-21934 The present invention relates to an improvement of a pile driving machine, such as a concrete pile or an H-shaped steel, which does not require a leader as in a conventional pile driving machine and is lower than a main cylinder. A pile catching mechanism is provided as an integrated unit in the concrete pile to catch concrete pile and H steel, and the head of the pile is the piston hammer of the main body cylinder.
A pile that has the advantage of being driven by a machine, does not emit noise, vibration, high-pressure gas, air, etc., and of course does not require a leader, and can be used even in a narrow space. This is a driving machine, and in the case of this method, it is possible to drive H-section steel and prevent twisting, but it is difficult to maintain the bearing capacity of the pile with respect to the ground or to use a pile with a structure that is further increased. is there . (7) Actual Utility Model Sho 63-2510 The present invention relates to an improvement of a sheet pile pushing device, first by excavating a steel mold building site with an earth auger, and then by excavating the next building site. Of the sheet pile for pushing the sheet pile into the excavation site, which cannot be used to rotatably insert the shape steel, and in this method, it is impossible to push the shape steel having the tip supporting force according to the present invention. Can not. (8) JP-B-62-3891 The present invention is a device for driving a pile by a method in which a hammer weight is lifted and dropped by a clutch mechanism that interlocks with a wire. Is provided with a pile catching mechanism and is configured such that the descending distance of the pile and the descending distance of the pile driver are always matched to accept the next impact regardless of the magnitude of the hammering force. This invention is also Japanese Patent Publication Sho 62-2
Similar to 1934, it is possible to drive the shape steel and prevent its twisting (since it is not rotationally driven), but it is impossible to drive the shape steel pile constructed so as to have the tip supporting force. (9) Japanese Patent Publication No. Sho 62-21932 The present invention relates to a method of pushing in a shaped steel pile, and first of all
This is a method of excavating the place where the shape steel piles are to be built with a girder, and then sequentially pushing the shape steel into the previously excavated place while excavating the next place of construction, in which the pushing reaction force is applied to the screw anchor.
A device configured to be obtained from
Like 510, it is impossible to erection the shaped steel while rotating, and in particular, it is not the erection of the shaped steel pile having the tip supporting force as in the present application. (10) Japanese Patent Application No. 60-29766 The applicant of the present application has previously provided a steel pile for retaining soil in Japanese Patent Application No. 60-29766, which is constructed by directly rotating the pile at the top of the pile. It adopts the method of incorporating. However, the pile of this consideration is an auger on solid ground.
A load is applied to the screw, the excavated portion is immediately collapsed in the gravel layer and the load is applied to the entire pile too much (the rotational moment of the steel pile is naturally insufficient with respect to the rotational force of the drive motor). The drawback is that the pile twists naturally. (11) Other conventional techniques In addition to the above, a method of driving a shaped steel pile with a Monken is adopted. However, when the supporting force of the tip of the shaped steel pile as a pile or the supporting force of ribs or webs is insufficient, It is not possible to settle or cast the shaped steel pile of the present invention.

も杭(足場)の沈下を防止せんとするものである。The type steel piles (H type steel, L type steel, rail type steel and the like piles) to be built for earth retaining or scaffolding are mainly H type steels or rail type steels used as piles. According to the state of the ground to be embedded, the means such as the above-mentioned rotation building method, placing method or pushing method have been adopted.
Each method has advantages and disadvantages, and in the case of shaped steel piles, the tip supporting area is extremely small, so the tip supporting capacity is insufficient, and especially when used as scaffolding piles, there are various inconveniences due to sinking of the piles. There is a problem that, when adopting the rotary excavation construction means as the pile construction means,
Since the pile is usually long, there is a shortage of the rotation moment of the shape steel pile with respect to the rotation moment of the drive motor, which causes the twist phenomenon of the pile during rotary installation. Exists. Therefore, the invention of the present application adopts a pivoting erection means as a method of erection of a shape steel pile, and improves the structure of the shape steel pile to prevent the twisting phenomenon of the shape steel pile due to the shortage of the rotation moment during rotation erection. In addition to the prevention, the pile supporting force is secured on any ground, and the sinking of the pile (scaffold) is prevented even when a heavy object is placed on the scaffold.

ない。Since the present invention has the above-mentioned structure, the shape steel pile (1) is replaced with the cylindrical steel pipe (10 ') or the fin casing.
It is fitted in a singing auger (8), and a rotational force receiver (12) is engaged in an engaging groove (11) or (11 ') as a clutch mechanism, on the other hand, a cylindrical steel pipe (10') or fin casing singing auger. The top of the gear (8) and the drive motor (7) suspended on the crane (22) of the work vehicle are engaged with each other by the clutch mechanism (21) to form the device of the present application, and the steel mold pile (1). ) Inside a cylindrical steel pipe (10 ') or fin casing auger
Suspend (8) with the crane (22), and drive motor.
(7) is turned to excavate the steel pile built-in ground. In that case, the drive motor (7) rotates the cylindrical steel pipe (10 ') or the fin casing auger (8), and the rotational force thereof is the clutch mechanism (11) (11') (12). ) To rotate the auger screw (4), the auger screw (4) excavates the built-in ground while rotating the shape steel (2). At this time, the excavation rotation diameter (R) of the auger screw (4) is slightly larger than the rotation diameters (R2) (R1) of the cylindrical steel pipe (10 ') or the fin casing auger (8). Therefore, the cylindrical steel pipe (10 ') or fin cage
The resistance of the built-in ground is small for the rotary excavation of the singing auger (8), and the rotational force of the drive motor (7) is almost the same as the clutch mechanism (11) ( 1
1 ') (12) is transmitted directly and does not weaken the excavation force of the auger screw (4). Further, the tip support plate and the rotation stabilizing plate (3) are almost the same as the external fitting steel pipes (8) and (10 ').
Since it is constructed so as to be inscribed on the outer surface of the steel pipe, the long and heavy shaped steel (2) is fitted into the outer fitting steel pipe (8) (1) during the excavation rotation.
0 ') even if a force that tilts acts, the stabilizer plate (3) is inscribed in the steel pipes (8), (10') to prevent the tilt, so that the auger screw (4) is driven. The direction is always stable. Moreover, since the earth and sand excavated by the auger screw (4) does not enter the outer fitting steel pipes (8) and (10 ') due to the presence of the tip supporting plate and the rotation stabilizing plate (3), especially the shape steel (2) Moreover, the force for cutting the rotational force, that is, the force for causing the twisting phenomenon does not work.

奏することになる。Since the device of the present invention has the above-mentioned structure and functions, unlike the conventional method and device for constructing the type steel pile, the motor directly driven to the steel mold (2) is used. -Because the rotating force of (7) is not applied and the resistance of the excavated earth and sand that reduces the rotating force during the rotation of the building is not received, that is, the rotating moment of the drive motor (7). Not only is there no direct relationship with the rotational moment of the shape steel, but the difference between the two moments is only a slight difference, and the twisting phenomenon of the shape steel (2) is completely prevented, and the shape steel pile ( There is no slight influence on the strength as 1). Further, the rotating diameter (R) of the excavation blade (9) of the auger screw (4) is different from that of the conventional one, and at least the outer fitting steel pipe (8) (1).
This is because the structure is formed to have a diameter larger than the rotating diameter of 0 '), which means that the tip supporting area, that is, the tip supporting force of the steel pile (1) in the built-in soil is much higher than that of the conventional steel pile. It has the great effect of being powerful. It should be noted that in the prior art, the twisting phenomenon becomes greater as the size of the advancing blade (9) becomes larger, and therefore the excavating blade could not be made large (the tip supporting force could not be increased). By using it, it became possible to increase the tip supporting force and prevent the shape steel from twisting. Furthermore, when building on a railroad bed or ground with a gravel layer, with the piles and methods shown in Japanese Utility Model Application No. 60-29766, even if the layer is dug, the gravel around the hole will collapse one after another. In addition to the fact that the shape steel piles were not smoothly rotated, and therefore the twisting phenomenon of the shape steels was great, the excavation was difficult or extremely inefficient, but in the present invention, the external fitting steel pipes (8) (10) were used. Since ') is used, the above inconvenience does not occur at all. Further, when the shape steel pile (1) on which the pile support plate (19) is formed is used as the shape steel pile (1), particularly in the case of a scaffolding pile on which soft ground or heavy objects are placed, the pile supporting force becomes stronger. Will be successful.
