It is required that.If pile body is all embedded in soil, cushion cap bottom surface is contacted with the soil body, then referred to as embedded footing on piles, low capped pile foundation;If ground is exposed in pile body top
Face and cushion cap bottom is located at ground or more, then referred to as elevated footing on piles.Building engineering field pile foundation is usually embedded footing on piles, low capped pile foundation plinth.It is high
In layer building, pile foundation is using more and more extensive.
Existing pile foundation pile foundation hole-forming device, simply by punching column, punch column on helical blade is set, to ground into
Row punching, the intensity for punching column is lower, and the planarization of punched hole hole inner surface wall is poor, and the soil on inner surface wall is easily fallen, shadow
It rings to pouring the quality of pile foundation, so can not meet the demand of user.
Utility model content
The purpose of this utility model is that: in order to solve existing pile foundation pile foundation hole-forming device, simply by punching column,
Helical blade is set on punching column, ground is punched, the intensity for punching column is lower, the planarization of punched hole hole inner surface wall
It is poor, the problem of soil on inner surface wall easily falls, influences the quality for pouring pile foundation, provide a kind of pile foundation hole-forming device.
The technical solution adopted in the utility model is as follows:
A kind of pile foundation hole-forming device, including column and helical blade are punched, it is provided with helical blade on the punching column, it is described
Grinding disc is welded with by column on punching column, the grinding disc is provided with multiple altogether, and multiple grinding disc are wrong along the vertical direction
On punching column casing is nested and fixed, and be welded with fixed disk on the appearance wall of casing in position setting at the top of the punching column,
Limited post is welded in the fixed disk, and the top of limited post is welded with sliding block.
Wherein, the punching column and helical blade are to pour integral structure.
Wherein, there are six the limited post is arranged altogether, and six limited posts are distributed in a ring, between adjacent two limited post
Spacing is equal.
Wherein, the cross section of the grinding disc is arcuate structure.
Wherein, it is welded with auxiliary connecting rod between the column and grinding disc, and assists there are two connecting rod is arranged altogether, and
And two auxiliary connecting rods are symmetrical about grinding disc.
Wherein, the limited post is parallel to each other with punching column.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, which is welded with grinding disc by column on punching column, and grinding disc is total
Be provided with it is multiple, and multiple grinding disc shift to install along the vertical direction punching column on, during use, drilling machine drive punching
Column rotation, when being punched by helical blade to ground, grinding disc can be rotated with the rotation of punching column, so as to right
The inner surface wall of hole is polished smooth, and ensure that the planarization on hole surface, is prevented the soil on hole surface from falling, is improved
The molding quality of hole, to further improve the quality that pile foundation pours.
2, it in the utility model, punches and casing is nested and fixed at the top of column, and be welded with fixation on the appearance wall of casing
Disk is welded with limited post in fixed disk, and the top of limited post is welded with sliding block, during use, can pass through limit
The annular hole opened up at the top of the sliding block of top end and drilling machine is slidably connected, and the setting of limited post, on the one hand can fight each other hole post
It is limited, improves its intensity, improve its stress intensity, the hole post that on the other hand can fight each other carries out rotary spacing, improves its turn
Dynamic stability.
