Description
【Technical field】
The utility model is related to build engineering field, and in particular to a kind of soil compaction club-footed pile shaped device.
【Background technology】
At present in the foundation engineerings such as building, water conservancy, highway, double helix extruded and extended pile is pile foundation form conventional at present, this
Construction method creeps into squeezed hole using bidirectional helix closed extruding-enlarging aiguille, in downward rotary drill squeezed hole by rotary drill out
The soil body can be squeezed into the wall of stake holes side, bidirectional helix closed extruding-enlarging aiguille is moved upwards and rotated squeezed stake holes again,
During the slump soil body can be squeezed into stake holes side wall in the stake holes in rotating up squeezed lifting, in upper rotation lifting simultaneously, start coagulation
Native pump fills piling to stake holes internal pressure.The subject matter of presence is first out to be transported up native rotary digging again being squeezed to the pile lining of both sides again
Pressure, therefore the soil for spinning out can block the conveying channel that rotating vane is formed, and easily produce bit bouncing phenomenon.And discharge
Soil or mud, increased bore forming difficulty and progress.
With the increase of building height, foundation pile is long to be stepped up, and the difficulty of pile foundation construction is also increasing.Existing stake
The bearing capacity of the bored concrete pile of foundation construction is mainly made up of stake end soil resistance and Pile side soil frictional force；The enlarged footing of pile foundation makes
Formed with cement high-pressure mortar spraying, but may be met using above-mentioned bored concrete pile under current complex geological condition and wanted
Ask.
Therefore, it is necessary to provide the soil compaction club-footed pile shaped device used under a kind of complex geological condition.
【Utility model content】
The purpose of this utility model is to provide a kind of soil compaction club-footed pile shaped device.
The technical solution of the utility model is as follows：
A kind of soil compaction club-footed pile shaped device, including the drilling rod with drill bit and base expanding and base expanding device, the drill bit include being formed at
The discharge opening of its outer wall, the base expanding and base expanding device includes concrete pump and the pipe of concrete connected with the concrete pump, the coagulation
Native pipe is contained in the drilling rod, and the spout of the pipe of concrete is connected with the discharge opening.
Preferably, the drilling rod includes the body being sequentially connected, stops circle and borded pile, and the borded pile is from the drill bit
Extend and formed, the body, stop circle, borded pile and drill bit are set with central shaft, and the internal diameter for stopping circle is more than the spiral shell
Rotation post and the body.
Preferably, the diameter of section of the pipe of concrete is 12-20 centimetres.
Preferably, it is described to stop that circle to the distance of the drill bit is 1-2 meters.
The beneficial effects of the utility model are：
1st, using the base expanding and base expanding device located at drilling rod, the enlarging to different soil properties is completed, the structure design is simple, low cost, effect
It is really good, be suitable to produce in batches and promote the use of.
2nd, stop coil structures to it is squeezed into the hole wall of stake carry out second extruding, stop that formation of pile soil is not screwed out
Direct squeezed pile, its structure is novel, pile quality is good, be difficult bit bouncing.
3rd, environmental protection, without mud discharge, without dregs outward transport, without construction fugitive dust, it is not necessary to deposit soil site, the environment of surrounding will not
It is contaminated.
【Brief description of the drawings】
