DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inclined ground support structure for an upright support such as a wire mesh fence, a construction method and an apparatus.

[0002]

2. Description of the Related Art Conventionally, a method for establishing a pillar such as a fence has been developed which is simple, quick and strong, and which does not require disposal of backfilled soil and which is advantageous in terms of occupational health (Japanese Patent Laid-Open No. 2000-2000).
-345742).

By the way, the above-mentioned establishment method was invented mainly on a flat ground, and on a slightly inclined ground, a concrete block (made of synthetic resin) is buried horizontally or an inclined pipe is used to erect the embedded pipe. The only possible method was to insert the lower end of the support upright into the inside of the support, fill the gap between the lower end and the inner periphery of the pipe with mortar, and harden and condense the support to erect the support.

For this reason, when the inclination angle of the inclined ground is small, the above-described conventional method is sufficient. However, when the inclination angle is relatively large (about 45 degrees at the maximum), it is difficult to cope with the conventional method. Met.

Prop establishment method A guide tube of the pipe is arranged inside a long hole, and a diametrically projecting pin of the guide tube is pivotally supported on a long wall of the long hole, and the guide tube is centered on the projecting pin. The pipe is supported movably in the longitudinal direction, and the guide pipe is A method of establishing an upright support on an inclined surface according to the first aspect of the invention, which is slidably fitted in a guide cylinder. An upright support on an inclined surface according to the first or second aspect of the invention. A guide support pipe guide tube is disposed inside the long hole, and a diametrically projecting pin of the guide tube is pivotally supported on a long wall of the long hole to support the guide tube movably in the longitudinal direction of the long hole. The device for establishing an upright support on an inclined surface which is made of a synthetic resin and has a vertical and horizontal width or a diameter larger than the height of the support plate. The device for establishing an upright support on an inclined surface according to the fourth or fifth aspect of the present invention, wherein a pipe avoiding surface is formed. The fourth to sixth aspects of the present invention, wherein anchor bolts are inserted through a plurality of bolt holes formed along the outer periphery of the support board. It is constituted by the device for setting upright props on the inclined surface according to any of the above.

Accordingly, the upper surface of the support plate (having a width or a diameter larger than the height) is exposed by being inclined in parallel with the inclined ground, and is buried in the ground in that state, and the longitudinal direction of the long hole is set in the inclined direction. The pipe is buried in the ground by being guided (along) along the long wall of the long hole in the upright direction in the state where it is arranged.

[0008] The soil in the pipe that has been cast is beaten and compacted with a stamp to form a space above the pipe, and the lower end of the column is inserted upright into the space, and the lower end and the inner periphery of the space are inserted. Mortar is filled and hardened and condensed in the gap with the surface, so that the column can be set upright.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A square, rectangular or circular support plate 2 is formed of a thermoplastic synthetic resin (such as hardened polyethylene) or a thermosetting synthetic resin (such as phenolic resin). This support board 2 has a width or a diameter of 200 mm in the vertical and horizontal directions and a thickness of 6 mm.
It has a height or width or diameter larger than its thickness (height) at 0 mm. A rectangular or oval long hole 1 is formed in the center, and the support plate 2 is equally spaced along four corners or the outer periphery. Then, four bolt holes 11 are drilled, and a fitting recess 13 of a bolt head 12 ′ is formed at the upper end of the bolt hole 11.

A pipe avoiding surface 10 is formed below the short wall 1 "of the long hole 1, and the support plate 2 is buried in the inclined ground 3 shown in FIG. The elongated hole 1 is substantially parallel to the surface 3, is exposed on the ground 3, and is arranged such that the longitudinal direction of the long hole 1 is inclined.

A strut supporting pipe 4 is erected in the upright direction along the long walls 1 'and 1' of the long hole 1 and is passed through the long hole 1 and along the pipe avoiding surface 10 to the ground 3 by a hitting flange 15 of a hitting machine 14. Tap and bury.

At the time of beating and embedding, the soil 5 in the pipe 4 is compacted by a stamp 16 provided on the lower surface of the flange 15, and a space s is formed above the pipe 4 by the compaction. Thereafter, the percussion machine 14 is raised to remove the stamp 16 from the space s, and the lower end 6 ′ of the upright support 6 is inserted into the space s, and the space between the outer periphery of the lower end 6 ′ and the inner periphery of the space s is inserted. The gap s ′ can be filled with mortar 7, which can be hardened and set to fix the column 6 upright on the inclined ground 3.

A guide tube 8 for the pipe 4 is disposed and accommodated in the elongated hole 1, and diametrically projecting pins 9, 9 are provided on an outer surface of the guide tube 8, and the pins 9, 9 are attached to the elongated wall 1. ', 1'
Are inserted into the shaft holes 17, 17 formed at the opposing positions of the pins 9 and 9 to pivotally support the pins 9 and 9 on the long walls 1 'and 1'. Along the pins 1 and 9 in the longitudinal direction of the long hole 1 so as to be freely movable.

As shown in FIGS. 1 and 3, the guide tube 8 has two long walls 1 'inside the elongated hole 1 inclined in the inclined direction.
The support plate 2 is buried in the inclined ground 3 by excavation or beating while the projecting pins 9, 9 are stopped and held upright along 1 ', so that the soil 5 also enters the guide tube 8, and the guide tube 8 8, the pipe 4 can be beaten by the striker 14 and buried underground.

The support plate 2 has a length R from the lower short wall 1 "to the lower end in the inclined direction larger than the length r from the upper short wall 1" to the upper end. It can be circular.

Therefore, as shown in FIG. 4, when a left moment M is applied to the column 6, the ground pressure P applied to the inclined side of the pipe 4 is large in the depth direction. Since the applied ground pressure P 'is large and the reaction force thereof is large, there is no sliding in the tilting direction of the support plate 2 and the reaction force P "is applied to the lower surface of the support plate 2 to oppose the moment M of the column 6, 6 is strengthened against the moment M.

Further, by inserting an anchor bolt 12 into the bolt hole 11 and driving the bolt 12 on the ground 3, the resistance M opposes the moment M by the resistance ground pressure Pa and the frictional resistance Pb corresponding to the moment M applied to the column 6. be able to.

The residual soil generated when the support plate 2 is buried is filled back into the space s "between the inner periphery of the elongated hole 1 and the outer periphery of the guide tube 8, or the space s" is filled with mortar.

In the drawing, reference numeral 18 denotes a bearing groove which can pivotally support the projecting pin 9 on the bottom face 17 of the groove 18 and which can be attached to and detached from the bottom face of the groove 18 through the upper end opening of the groove 18. Can be.

[0020]

According to the present invention, since the method, the support and the device described above are used, a support such as a fence can be easily and quickly and firmly established on an inclined ground, and there is no need to treat the backfilled soil, and the work required for occupational hygiene is reduced. There is little necessity, and there is an effect that the upright support can be safely established on the inclined ground.
