As an improvement, the outer casing is also made of more piece cylinder, pass through cuff between the more piece cylinder of the outer casing of composition
It is weldingly connected.
As an improvement, main ribs are uniformly distributed in interior casing surrounding, welded together by hoop of putting more energy between main reinforcement.
As an improvement, the reinforcing rib runs through inside and outside casing, and 5-10cm is stretched out in outer casing outer surface.
As an improvement, the interior casing and outer casing are equipped with the eyelet passed through for reinforcing rib, after reinforcing rib passes through eyelet,
It is welded and fixed at eyelet.
As an improvement, the reinforcing rib is distributed on inside and outside casing cross section in well word.
As an improvement, the reinforcing rib is uniformly distributed along inside and outside casing axis direction interval.
A kind of hollow no stirrup friction pile construction method, which is characterized in that include the following steps：
Step 1: surveying setting-out goes out stake position, drill according to the prior art, and borehole cleaning extremely design or code requirement；
Step 2: interior casing and outer casing are fixed together by reinforcing rib；
Step 3: the inside and outside casing being fixed together is sling in decentralization to the stake holes being drilled；
Step 4: the space casting concrete between interior casing and outer casing；
Step 5: after concrete curing, filling concrete magma and earth mixtures in interior casing are completed empty after solidification
The heart is without stirrup friction pile driving construction.
As an improvement, the interior casing and outer casing are made of more piece cylinder, first with reinforcing rib by inside and outside casing
A pitch circle cylinder be welded and fixed together, sling transferred in stake holes with crane later, inside and outside the section casing cylinder decentralization after,
Main reinforcement is welded on interior casing, and welds the cylinder of casing in another section using main reinforcement, utilizes cuff to weld outside another section later
Then the cylinder of casing transfers a section cylinder heights again, so repeat, until inside and outside casing reaches projected depth.
Present invention has the advantages that：
The design of the invention carries inside and outside combination casing, and interior casing is centrally through reinforcing rib and cement mortar original soil knot
Integrator, outer casing stretch out reinforcing rib end and increase the contact point with soil, further enhance entire pile body and soil
Frictional force, pile body is without using stirrup, the problems such as avoiding common stirrup desoldering, saves material, rationally backfills original soil, save
Transportation cost, while the problem of inside and outside casing avoids collapse hole after a pore-forming, adapting to construction condition variation, ensure that pile body
Bearing capacity.

Specific implementation mode
The present invention is illustrated below in conjunction with the accompanying drawings,
As shown in Figure 1 to Figure 3, a kind of hollow no stirrup friction pile, including combination casing, the combination casing is by concentric locking collar
The interior casing 5 and outer casing 4 of folded setting form, and the reinforcing rib 7 that the two is fixedly linked, the reinforcement are equipped between inside and outside casing
Muscle 7 is stretched out from 4 surface of outer casing, space casting concrete 2,5 inside filling concrete magma of interior casing and soil between inside and outside casing
Mixture, i.e. cement mortar original soil 3, the interior casing 5 are made of the cylinder of more piece thin-walled, form in casing 5 more piece cylinder it
Between be weldingly connected by longitudinal main reinforcement 6, main reinforcement 6 is welded with interior casing 5 by edge；The outer casing 4 is also by more piece thin-walled
Cylinder composition, form and be weldingly connected by cuff 8 between the more piece cylinder of outer casing 4, main ribs 6 are in 5 circumferential direction of interior casing
It is uniformly distributed, is welded together by hoop of putting more energy between main reinforcement 6, inside and outside casing is made of thin-wall steel pipe.
The reinforcing rib 7 is distributed on inside and outside casing cross section in well word, uniform along inside and outside casing axis direction interval
Distribution.The interior casing 5 and outer casing 4 are equipped with the eyelet passed through for reinforcing rib 7, after reinforcing rib 7 passes through eyelet, at eyelet
It is welded and fixed.The reinforcing rib 7 runs through inside and outside casing, and stretches out 5-10cm in 4 outer surface of outer casing.
Outer casing 4, interior casing 5 are processed：According to the size of design stake diameter, the making of casing is carried out in factory, outer casing 4 is same
