Description
Technical field
The present invention relates to a kind of cast-in-place pile construction method, specifically, be a kind of cast-in-place pile construction method using double casing to pass through deep metalling.
Background technology
Wall protecting method many employings mud off of the most conventional bored concrete pile.But bored concrete pile of constructing in some deep & thick silt layers, the effect of mud off is frequently not very well, it may appear that a lot of problem such as collapse hole, undergauge, sediment.
In order to solve the problems referred to above, the method occurring in that full casing construction bored concrete pile, i.e. first steel pile casting sinking is put in place before construction bored concrete pile, then bored concrete pile of constructing under the protection of steel pile casting.The most conventional lower steel pile casting method has: rotary (the full casing of Spiral digging machine band, pipe rubbing machine, full circle swinging etc. represent equipment), vibration type (vibration hammer etc. represent equipment), paddle type mill (impact pile driving machine etc. represent equipment), static pressure type (static pile press etc. represent equipment).
Above-mentioned construction equipment is the most no problem when constructing soft layer, but running into top backfill deep (10 meters) metalling, bottom be again soft layer simultaneously steel pile casting diameter 1 meter and above time, some equipment often runs into the situation that difficulty even cannot be sunk.Vibration hammer is also a kind of equipment that lower casing is conventional, but its sinking casing in deep rubble is also at a loss what to do.
Currently for this Special Geological Condition, the construction equipment that can use is little, and full circle swinging equipment can be used, but its efficiency of construction is the lowest, is not suitable for large quantities of engineering pile.Most recently newly go out a kind of device name be multifunctional drill, carry two unit heads, a unit head drives casing to sink, and another unit head drives long screw drill rod to fetch earth.But current equipment construction ability can only casing within construction diameter 800mm.There is a method in which and join special double-walled casing for high-power rotary drilling rig, efficiency is fast compared with full circle swinging.But, three of the above method have one what is common is that construction equipment is few, equipment purchasing price high.
Therefore the cast-in-place pile construction method passing through deep metalling known to also exists above-mentioned all inconvenience and problem.
Summary of the invention
The purpose of the present invention, is to propose a kind of cast-in-place pile construction method using double casing to pass through deep metalling using vibration hammer that steel pile casting passes through deep metalling.
For achieving the above object, the technical solution of the present invention is:
A kind of cast-in-place pile construction method using double casing to pass through deep metalling, it is characterised in that comprise the following steps:
A, clamping the groove part of outer steel pile casting with the fixture of vibration hammer, vibration-sunk is to flushing with ground；As relatively big in the power that is hampered, continue to sink to position after being drawn out by inside soil stone core with Spiral digging machine；The long 10m of outer steel pile casting, internal diameter 1.2m, wall thickness 15mm；
B, with Spiral digging machine the native stone core in outer steel pile casting drawn take clean；
C, interior steel pile casting of slinging with vibration hammer, through outer steel pile casting, shake interior steel pile casting and sink to overhead 200-300mm；The long 25m of interior steel pile casting, internal diameter 1m, wall thickness 15mm；
D, clamp the hanger being arranged on outer steel pile casting with vibration hammer, extract outer steel pile casting；
E, fetch earth in interior steel pile casting with Spiral digging machine, until designed elevation；
F, descending reinforcing cage；
G, casting concrete；
H, extract interior steel pile casting with vibration hammer, complete bored concrete pile and pour.
The cast-in-place pile construction method using double casing to pass through deep metalling of the present invention can also be further achieved by the following technical measures.
Aforesaid method, in wherein said step a, soil stone core is drawn out facility and is used punching to grab cone.
Aforesaid method, wherein said interior steel pile casting uses 16Mn steel matter, and the upper and lower two ends of interior steel pile casting are respectively provided with Reinforced Hoop.
Aforesaid method, wherein said outer steel pile casting uses 16Mn steel matter, and the upper and lower two ends of outer steel pile casting are respectively provided with Reinforced Hoop.
Aforesaid method, wherein said vibration hammer selects electric vibrating hammer or hydraulic vibration driver.
After using technique scheme, the cast-in-place pile construction method using double casing to pass through deep metalling of the present invention has the advantage that
1, without expensive special equipment, the construction of the common equipment such as vibration hammer and ordinary steel casing is only used；
2, construction quality is safe and reliable, be beneficial to organizing construction, and speed of application is fast, and cost is low；
3, Construction Cost is reduced.
Accompanying drawing explanation
Fig. 1 is the double casing sinking schematic diagrams in the filling pile construction of the embodiment of the present invention.
In figure: 1 vibration hammer, 2 fixtures, steel pile casting in 3,4 hangers, 5 outer steel pile casting.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, the present invention is illustrated further.
Embodiment 1
Referring now to the double casing sinking schematic diagrams in the filling pile construction that Fig. 1, Fig. 1 are the embodiment of the present invention.
Double casing that uses of the present invention passes through the cast-in-place pile construction method of deep metalling, it is characterised in that comprise the following steps:
A, fixture 2 with electronic vibration hammer 1 clamp the groove part of outer steel pile casting 5, and vibration-sunk is to flushing with ground；As relatively big in the power that is hampered, continue to sink to position after being drawn out by inside soil stone core with Spiral digging machine；The outer long 10m of steel pile casting 5, internal diameter 1.2m, wall thickness 15mm；Described outer steel pile casting (5) uses 16Mn steel matter, and the upper and lower two ends of outer steel pile casting are respectively provided with Reinforced Hoop.
B, with Spiral digging machine the native stone core in outer steel pile casting 5 drawn take clean.
C, interior steel pile casting 3 of slinging with vibration hammer, through outer steel pile casting 5, shake interior steel pile casting (3) and sink to overhead 200-300mm；The long 25m of interior steel pile casting, internal diameter 1m, wall thickness 15mm；Described interior steel pile casting 3 uses 16Mn steel matter, the upper and lower two ends of interior steel pile casting to be respectively provided with Reinforced Hoop.
D, clamp the hanger 4 being arranged on outer steel pile casting 5 with vibration hammer 1, extract outer steel pile casting 5；
