More specifically, the present invention relates to a screw guide tool for guiding the screw and head of a continuous auger machine along the already driven steel sheet piles for driving steel sheet piles.

Various cross-sectional shapes of steel sheet piles have been proposed, and the steel sheet piles have a structure that fully engages with each other during driving and provides watertightness. When driving steel sheet piles into the ground, if the ground is hard, use a continuous auger or other means to drill holes or loosen the ground before driving the steel sheet piles into the ground.

法及びその装置が記載されている。 For example, in Japanese Patent Application Laid-open No. 55-142826, an earth auger is attached to the tip of the boom of a crane machine, and steel sheet piles are press-fitted into the auger screw at the same time.
A press-in method and its equipment are described in which when a predetermined depth is reached, only the steel sheet pile remains in the soil and the earth auger is pulled out.

It is necessary to drill holes accurately at the installation location. However, it is difficult to accurately drill holes along the edges of steel sheet piles because the hardness of the rock is uneven, and even if the head is positioned accurately, it will bend during drilling.
For this reason, methods such as re-drilling the holes were taken, which resulted in the problem of prolonging the construction period.

What is shown in FIG. 1 is a diagram showing a press-in construction method using the screw guide of the present invention. The wheel crane vehicle 1 is a normal wheel crane vehicle 1
It has a similar structure, but the one used in this press-in method has been modified to have a special function. This wheel crane vehicle 1 is described in detail in Japanese Patent Application Laid-Open No. 112924/1983, which has already been filed by the present applicant, and will therefore be omitted here. A telescopic boom 3 is swingably provided on a vehicle body 2 of a wheeled crane vehicle 1. In order to swing the telescopic boom 3, a traction cylinder device 4 is rotatably provided between the vehicle body 2 and a piston of the traction cylinder device 4 is rotatably provided between the telescopic boom 3 and the vehicle body 2. . A sub-boom 5 is provided at the tip of the telescopic boom 3 so as to be freely retractable. At the tip of the sub-boom 5,
An auger device 10 is swingably provided.

い。 One end of a screw 11 is fixed to the auger drive device 10. A head 12 is fixed to the other end of the screw 11. The head 12 is
It is for drilling holes in the ground, and is a well-known type that is selected depending on the type of ground. A screw guide 15 is provided in the intermediate portion of the screw 11 near the head 12 side. Two flanges 16, 1 at a distance from the screw 11
6, and a cylindrical main body 17 is rotatably provided on the shaft 13 of the screw 11 between the flanges 16, 16. (FIGS. 2 and 3) One end of the connecting members 18, 18 is fixed to the outer periphery of the cylindrical body 17, and a guide tool 20 is fixed to the other end of the connecting members 18, 18. In this embodiment, these fixings are all integrally fixed by welding. The guide tool 20 has a U-shaped cross section and is provided so as to enclose the steel sheet pile 30 in the U-shaped internal space 21. The screw guide 15 may be smoothly guided in the longitudinal direction of the steel sheet pile 30.

置１０に伝えられる。How to use the screw guide tool: Insert the steel sheet pile 30 into the internal space 21 of the guide tool 20. The auger drive device 10 is started and the screw 11 is driven to rotate. The guide tool 20 is a steel sheet pile 3
Since rotation is restricted to 0, it does not rotate. Since the cylindrical body 17 rotatably holds the shaft 13 of the screw 11, the screw 11 rotates stably without swinging. The head 12 drills a hole in the ground. During this drilling, the traction cylinder device 4
operates and pulls the telescopic boom 3 strongly. This tensile force is transmitted to the auger device 10 from the tip of the sub-boom 5.

０に沿つた削孔ができる。 An axial pressing force is applied to the screw 11 from the auger drive device 10. Theoretically, this pressing force is applied in an amount approximately equal to the weight of the crane vehicle 1 with the largest wheels. When the head 12 drills a hole in the ground and the screw 11 is lowered, the screw 11 is added. Also, the length of the sub-boom 5 is adjusted and constantly added. In addition, the length of the sub-boom 5 is adjusted so that the screw 11 always maintains a correct posture during operation. The guide tool 20 descends while being guided by the steel sheet pile 30. At the same time, the cylindrical body 17 prevents deflection and eccentricity of the screw 11, so the existing steel sheet pile 3
It is possible to drill holes along 0.

It is corrected by the screw guide 15. When the auger drilling is completed to the ground position where the steel sheet pile 30 is to be driven, the screw guide tool 15 and the screw 1
1. Operate the traction cylinder device 4 to pull up the auger drive device 10. The next steel sheet pile 30 is driven into the drilled ground using conventional construction methods such as an auger casing vibro and a press-in machine. The steel sheet pile 30 is placed by repeating this operation.

も良い。[Other Examples] In the turning example described above, a hole was drilled in the ground with the head 12, but instead of drilling a hole, the steel sheet pile 3 was constructed using the same construction method as described above.
It's okay to just figure out when it's 0. In the construction example shown in FIG. 4, the press-fitting of the steel sheet pile 30 and the auger drilling are performed simultaneously at the same speed. The steel sheet pile 30 is press-fitted by a known press-in machine 40 and holes are drilled while the steel sheet pile 30 is held and guided by the screw guide tool 15 described above. In this case, head 12 uses a large magnifying head. Although the wheel crane vehicle 1 described above is a special one, it is not limited to the one described above, and may be a general continuous auger machine having a leader.

is smoothly guided along the steel sheet pile 30. Also,
The inner circumferential surface of the cylindrical body 17 and the shaft 13 slide better, and the screw 11 rotates smoothly. Note that a solid lubricant such as graphite, a high viscosity lubricating oil, or clay such as bentonite may be interposed between these materials.
