Problems solved by technology
Its disadvantages: First, the formed pile is still a single-column cement-soil pile. The single-column cement-soil pile on a soft soil foundation has a small area of the pile foundation, the soil around the pile is thin and soft, and the vertical support force is not enough to support the single-column cement pile. The soil pile is kept vertical, so it is very easy to cause the formed single-column cement-soil pile to tilt and be scrapped; second, because the cement slurry and soil in the single-column cement-soil pile are stirred in the same direction, it is impossible to make the gap between the cement slurry and the soil The mixing cannot be uniform, which will inevitably lead to the low strength of the formed single-column cement-soil pile.

Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as figure 1 As shown, a multi-angle bored pile includes a pile body 10, the pile body 10 is a cement pile or a concrete pile, and the cross section of the pile body 10 has more than three arc-shaped angles 11, that is to say, The pile body 10 is non-cylindrical but has more than three arc-shaped corners 11 on its outer surface.
[0031] The pile body 10 is formed by stacking several pile bodies 20, and the number of the pile bodies 20 is not less than the number of angles 11. That is to say, there may also be pile bodies 20 inside the pile body 10, but the pile body 10 The inner pile body 20 does not show an arc-shaped corner 11 outside the pile body 10, and the axis lines of the several pile bodies 20 are not on the same plane. It can also be understood that when the axis lines of the pile bodies 20 are connected to eac...

The invention relates to a quincunx drilling pile with good verticality, good inclination resistance capacity and full load bearing capacity and a forming method. The quincunx drilling pile comprises a concrete drilling pile, wherein two end surfaces and the pile body of the concrete drilling pile are formed by connecting a plurality of plum blossom petals. The quincunx drilling pile has the advantages that firstly, as the bearing area of a pile foundation of the quincunx concrete drilling pile distributed at multiple angles is large, and bearing supporting points are distributed in a polygon way, the stability of the pile foundation is good; secondly, when the pile body formed by polygon plum blossom petals is positioned in a soft soil foundation, a plurality of plum blossom petal pile bodies with the same included angles which are like a plurality of raised shores are acted on the wall of the soft soil foundation, and the concrete soil pile is ensured to be not inclined and to be vertically erected in the soft soil foundation.
Description
technical field [0001] The invention belongs to the technical field of construction, and relates to a cement bored pile and a forming method thereof, in particular to a polygonal bored pile and a forming method thereof. Background technique [0002] Bored piles are made of underwater concrete, which is mechanically formed. Existing bored piles are drilled by a drilling rig, and cement slurry is poured during the drilling process, and the borehole is filled with cement slurry after reciprocating several times to form a mud-water mixed column, which is a bored pile after solidification and molding. But existing bored piles are all single-column piles, and when higher pull-out resistance and pressure resistance are required, the aperture of the borehole needs to be enlarged so as to make a drilled pile with a larger aperture. [0003] Chinese patent literature discloses a pile-forming operation method of two-way mixing pile [Notice number: CN1632233A], including the following ...
