The forming cavity matched, above-mentioned core is cylindrical；
B, matched moulds：By external mold it is horizontal and make the U-shaped opening of external mold upwards, then core is inserted at above-mentioned forming cavity simultaneously
Core is fixed；
C, casting：In the forming cavity that concrete material is uniformly injected into above-mentioned external mold, and make above-mentioned concrete material abundant
It is wrapped on the outside of core；
D, ram-jolt：Concrete material ram-jolt using existing concrete ram-jolt equipment to above-mentioned forming cavity everywhere；
E, form removal：When concrete material at chamber to be formed is pre-hardening, then core is extracted out in external mold, treat concrete material
The hollow square pile of shaping is split out by external mold when solidifying completely.
This preparation method creativeness uses external mold and core, and external mold with forming and hollow side therebetween after core matched moulds
The cavity that stake matches.
Concrete material is directly injected at above-mentioned cavity, then by mixed mud ram-jolt.Certainly, concrete ram-jolt is
Existing mature technology.For example, ram-jolt directly can be carried out to it using existing concrete shock club.
After first splitting out core after concrete initial set, the pile body after shaping is torn open by external mold after after concrete completely solidification
Unload.Due to external mold upper opening, therefore, the pile body after shaping conveniently can be separated smoothly with external mold.
It is uniform on the inside of external mold and on the outside of core in described step A in the preparation method of above-mentioned hollow square pile
It is coated with separating medium.
In the preparation method of above-mentioned hollow square pile, described separating medium is graphite powder.
In the preparation method of above-mentioned hollow square pile, described separating medium is lubricant grease.
In the preparation method of above-mentioned hollow square pile, external mold is stretched out at the two ends of the step B core moulds.
Such structure can mold complete pile body, while the support that the core end stretched out can also be stablized.
In the preparation method of above-mentioned hollow square pile, end plate, two pieces are respectively mounted in the step B at the two ends of external mold
It is connected between end plate by prestressed steel bar.
In the preparation method of above-mentioned hollow square pile, the end matches with external mold port.
In the preparation method of above-mentioned hollow square pile, the two ends of the step B core moulds are carried out by corresponding support
Support positioning.
In the preparation method of above-mentioned hollow square pile, the presetting period of concrete is 3-4 hours in the step E.
In the preparation method of above-mentioned hollow square pile, the complete setting time of concrete is 4-10 small in the step E
When.
Compared with prior art, the preparation method of this hollow square pile is horizontal by external mold due to only needing to, then core is loaded
In external mold, the pile body uniform with fine aggregate distribution with regard to coarse aggregate can be molded after casting concrete raw material, therefore, using our legal system
The hollow square pile quality of work is high.
Simultaneously as just first tearing core open place when concrete material is pre-hardening, therefore, demoulding stability is also higher, tool
There is very high practical value.
