The utility model is further arranged to：Length direction sliding of the limiting plate along piling bar is connected on piling bar simultaneously
Fixed by screw with piling bar.
According to different soil properties, the amount that piling bar is driven into soil can be different, by using above-mentioned technical proposal, limit
Position plate can on piling bar up and down adjusting position so that piling bar can be driven into different soil properties, expands it and use scope.
The utility model is further arranged to：It is arranged with to be provided with fixed plate, the fixed plate on the piling bar and supplies steel
The through hole that stake is passed through, the fixed plate is fitted on step plane, and the orthographic projection of the limiting plate is projected in fixed plate.
By using above-mentioned technical proposal, the setting of fixed plate makes piling bar toward during squeezing into soil, limiting plate
It can directly contradict in fixed plate, so that limiting plate is difficult to be trapped in soil.
The utility model is further arranged to：The side of the fixed plate is provided with inserted link, and opposite side is provided with and inserted link
The slot that grafting coordinates, inserted link is inserted into slot so that two pieces of adjacent fixed plates are stitched together.
By using above-mentioned technical proposal, adjacent fixed plate is stitched together by way of grafting be linked to be one it is whole
Body, so that fixed plate is more stable, is less prone to situation about sinking into soil.
The utility model is further arranged to：The fixed plate is inserted into the side slope of hole body close to the side of hole body side slope
It is interior.
By using above-mentioned technical proposal, in the side slope that fixed plate is inserted into hole body, fixed plate can be further fixed.
The utility model is further arranged to：Tapped through hole is provided with the fixed plate, the tapped through hole inward turning is set
There is screw rod, the screw rod is screwed in step plane.
By using above-mentioned technical proposal, the setting of screw rod can play effect spacing up and down to fixed plate, make it not
The phenomenon easily beated.
The utility model is further arranged to：Some sandy soil are provided with the space formed between piling bar and hole body side slope
Bag.
By using above-mentioned technical proposal, the stacking of sand bag can reduce hole body slope failure and the office because of soil property saturated yielding
The phenomenon that portion caves in.
In summary, the utility model has the advantages that：When piling bar is down driven into soil,
Limiting plate is provided with the side wall of piling bar, limiting plate can facilitate workman to observe the depth that piling bar is driven into soil, when spacing
Plate stops squeezing into after contradicting onto fixed plate, and such structure can conveniently control every piling bar to be driven into the amount in soil,
Make workman that channel-section steel and piling bar be fixed up more easily by bolt, it is convenient to install.
