Embodiment 1
Fig. 1, Fig. 2 and Fig. 3 are refer to, the present embodiment provides a kind of dowel pilework 100.Dowel pilework 100 includes leading
To spacer bar 120 and four boundling reinforcing bars 110.
Boundling reinforcing bar 110 is included by two coaxially connected lengths of rebar of reinforced bar sleeve 130, respectively the first lengths of rebar 111
With the second lengths of rebar 112.It is be arranged in parallel between four boundling reinforcing bars 110, the side wall of reinforced bar sleeve 130 is the same as boundling adjacent thereto
The side wall of the lengths of rebar of reinforcing bar 110 offsets, and has gap 140 between adjacent two boundling reinforcing bars 110.Guide-localization reinforcing bar 120
Gap 140 is located at along the axially arranged and guide-localization reinforcing bar 120 of boundling reinforcing bar 110, guide-localization reinforcing bar 120 is connected to adjacent
Between two boundling reinforcing bars 110.
Boundling reinforcing bar 110 is coaxially connected by the progress of corresponding lengths of rebar by using reinforced bar sleeve 130, can be achieved to boundling
The flexible assembling of the length of reinforcing bar 110, make the selection variation of the length of boundling reinforcing bar 110.In addition, adjacent two boundling reinforcing bars
It is to realize to connect by guide-localization reinforcing bar 120 between 110, and axial direction of the guide-localization reinforcing bar 120 along boundling reinforcing bar 110 is set
Put, not only increase the contact area between guide-localization reinforcing bar 120 and boundling reinforcing bar 110, improve connection effect, also make phase
Spacing between adjacent two boundling reinforcing bars 110 diminishes, and gap 140 is diminished, helps to make the dowel pilework 100 ultimately formed
Volume diminish.
On the other hand, it is be arranged in parallel between four boundling reinforcing bars 110, and the side wall of reinforced bar sleeve 130 is the same as adjacent thereto
The side wall of lengths of rebar of boundling reinforcing bar 110 offset, this to combine between adjacent two boundling reinforcing bars 110 even closer, makes
Gap 140 reduces, and is advantageous to reduce the diameter of guide-localization reinforcing bar 120, mitigates the weight of guide-localization reinforcing bar 120, makes final
The close structure of the dowel pilework 100 of formation and deadweight is smaller, is easy to carry and constructs, save material, advantageously reduce
Cost.Meanwhile the side wall of reinforced bar sleeve 130 offsets with the side wall of the lengths of rebar of boundling reinforcing bar 110 adjacent thereto, along boundling steel
The radial direction of muscle 110, make the junction of two lengths of rebar of boundling reinforcing bar 110 even closer, it is not easy to occur to break away or deform.And
And the side wall and the side wall of reinforced bar sleeve 130 of the lengths of rebar of adjacent boundling reinforcing bar 110 offset, above-mentioned lengths of rebar is to reinforcing bar set
Cylinder 130 have support and fixation, can further improve reinforced bar sleeve 130 stability and lengths of rebar junction it is strong
Degree, the bulk strength of dowel pilework 100 is improved, improve the ability of confrontation high thrust, dowel pilework 100 is applied to deep layer
The improvement on high thrust landslide.
It should be noted that in other embodiment of the present utility model, boundling reinforcing bar 110 can also be by reinforced bar sleeve
The lengths of rebar of 130 three, four or more coaxially connected roots is formed, if keep the side wall of reinforced bar sleeve 130 with its phase
The side wall of the lengths of rebar of adjacent boundling reinforcing bar 110 offsets.Preferably, the quantity of boundling reinforcing bar 110 is 3~4.
Further, in the present embodiment, the length of the first lengths of rebar 111 is more than the length of the second lengths of rebar 112, arbitrarily
First lengths of rebar 111 of the reinforced bar sleeve 130 of a piece boundling reinforcing bar 110 and adjacent boundling reinforcing bar 110 offsets, whole boundlings
The end wall of reinforcing bar 110 is respectively positioned on same plane.Further, preferably, the reinforced bar sleeve of adjacent two boundling reinforcing bars 110
130 are not less than the diameter of 35 times of boundling reinforcing bars 110 along the axial spacing of boundling reinforcing bar 110.
Further, in the present embodiment, four boundling reinforcing bars 110 surround the tendon of ring-type.Four boundling reinforcing bars 110
By rounded perpendicular to the cross section that the same plane of its axial line is intercepted, and the cross section of four boundling reinforcing bars 110
The center of circle is in same circumference.
Above structure to be connected to more regular, close, any one boundling of arranging between four boundling reinforcing bars 110
The reinforced bar sleeve 130 of reinforcing bar 110 offsets with the first lengths of rebar 111 of adjacent boundling reinforcing bar 110, also causes four boundling steel
Interaction force between muscle 110 tends to balance, and makes the inside uniform force of dowel pilework 100, avoids the occurrence of local pressure
Excessive situation, improve the overall intensity of dowel pilework 100 and the resistivity to thrust.
Further, in the present embodiment, guide-localization reinforcing bar 120 is in rod-short.Each gap 140 is equipped with more
Guide-localization reinforcing bar 120, axial uniform intervals of the more guide-localization reinforcing bars 120 along boundling reinforcing bar 110 in each gap 140
Set.
The structure can effectively reduce the gross weight of guide-localization reinforcing bar 120, but the connection to guide-localization reinforcing bar 120 is strong
Degree influences little with connection effect, not only ensure that between boundling reinforcing bar 110 there is good connection effect, also allows anchor pile knot
The deadweight of structure 100 substantially reduces.Make carrying, construction to dowel pilework 100 more convenient, meanwhile, guide-localization reinforcing bar
The dosage of 120 pairs of raw material also greatly reduces, and guide-localization reinforcing bar 120 can also be served as using the cutting clout of reinforcing bar,
The utilization rate to raw material is substantially increased, and reduces the consumption of raw material.
Further, in the present embodiment, dowel pilework 100 also includes suspension ring reinforcing bar 150, and suspension ring reinforcing bar 150 is along collection
