Description
Technical field
The present invention relates to the realm of building construction, and in particular to a kind of cast-in-place concrete pile head shaping equipment and its user
Method.
Background technique
Coastal soft clay area engineering construction is fast-developing, and as the common base form of building, pile foundation is adopted extensively
With.Pile foundation is divided into prefabricated pile and bored concrete pile according to construction method.Prefabricated pile needs prefabrication, and transport is inconvenient.Bored concrete pile uses
The mode of poured in place concrete, cast-in-situ concrete poured pile constructing process is simple, strong operability, and convenient for detection, single pile is held
It is high to carry power, diameter can be very big, therefore, obtains in the ground foundation engineerings such as architectural engineering, traffic engineering and municipal works
It is widely applied.
However, being got over when construction bored concrete pile since surface soil layer is softer, and closer to earth's surface soil pressure in soft soil foundation
It is small, thus concrete poured in stake holes after soil lateral pressure effect of contraction it is inadequate so that pile concrete to surrounding soil squeeze
Out, the size and shape of design are not achieved.
In the filling process of in situ concrete pile, it can usually be extracted in situ concrete pile mold process after perfusion
The deformed problem of stake top occurs, it is costly so as to cause the post-processing of pile crown, cause unnecessary waste, and casting
Environment can also be impacted with the processing mode of row's concrete.It strikes the mode of chisel when selection to handle pile crown, and can shadow
Ring the quality for arriving entire in situ concrete pile pile foundation.
Summary of the invention

2) stake machine is in place, makes the center of mould sharp (502) alignment former (1) of a mould (5)；
3) it is pushed down above bearing plate with weight, or is directly connected to a machine, push down bearing plate by the self weight of stake machine；
4) stake mould (5) slowly sinks, and so that mould sharp (502) is slowly insert molded device (1), then stake mould (5) is slow across former (1)
It is slow falling enter ground in, reach projected depth；
5) start concrete perfusion, start upper pile pulling mould (5) after being injected more than the concrete of 1/3 height of a mould, draw out benefit on side
Fill concrete；Former (1) is pushed down by weight or the self weight of stake machine, remains motionless；
6) after stake mould (5) is extracted completely, a machine is removed, the weight on bearing plate is removed, adjusts concrete later；It is set according to stake top
Absolute altitude is counted, former (1) inner concrete amount is adjusted；If top of concrete height exceeds designed elevation, part concrete is dug out；
If top of concrete height is lower than designed elevation, continue to add a certain amount of concrete into pile crown former (1)；Finally make to mix
Solidifying soil top surface absolute altitude reaches designed elevation；
7) after the initial set of pile crown former (1) inner concrete, by lifting lug I (201) and lifting lug II (301) by pile crown former (1)
Ground is extracted, then takes former (1) away from pile body, achievees the purpose that pile crown is formed.
3. a kind of application method of cast-in-place concrete pile head shaping equipment according to claim 1 or claim 2, which is characterized in that
The cross sectional shape of the former (1) is determined according to pile body section to be poured, the cross sectional shape of former (1) with it is to be poured
The pile body cross sectional shape built is consistent；The cross sectional shape of the former (1) can be circle, rectangle, X-shaped or Y shape.
4. a kind of application method of cast-in-place concrete pile head shaping equipment according to claim 1 or claim 2, which is characterized in that
The former (1), which sinks to ground, can place weight pushing realization in bearing plate I (2) and bearing plate II (3), can also be direct
Stake machine is installed on, the strength of pushing is provided on bearing plate.
5. a kind of application method of cast-in-place concrete pile head shaping equipment according to claim 1 or claim 2, which is characterized in that
Type chamber (105) sectional dimension of the former (1) is greater than pile body sectional dimension to be poured.
