In figure, 1: conduit tapered hollow plug; 2: secondary pouring conduit; 3: lower funnel; 4: sealing ring; 5: drilling pouring pile hole; 6: concrete perfusion first; 7: mud; 8: secondary pouring concrete.
Detailed description of the invention
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples for illustration of the present invention, but can not be used for limiting the scope of the invention.
As shown in Figure 1, the drilled pile secondary tubing string pile making device of the present embodiment comprises: secondary pouring conduit 2, be connected to the conduit hollow taper plug 1 of secondary pouring conduit 2 bottom nozzle and be connected to the lower funnel 3 of secondary pouring conduit 2 top ports.
Conduit hollow taper plug 1 is the pyramidal structure of hollow, and the bottom of secondary pouring conduit 2 can be inserted in first in concrete perfusion 6 through the mud 7 in drilling pouring pile hole 5 by conduit hollow taper plug 1.
Conduit hollow taper plug 1 can be tightly connected by the bottom nozzle of sealing ring 4 with secondary pouring conduit 2.
The drilled pile secondary pouring piling method applying above-mentioned drilled pile secondary pouring pile making device in the present embodiment comprises the following steps:
S1. the concrete perfusion first 6 being positioned at bottom in drilling pouring pile hole 5 pours into mud 7.
S2. conduit hollow taper plug 1 is connected on the bottom nozzle of secondary pouring conduit 2 by sealing ring 4, the bottom nozzle of secondary pouring conduit 2 is sealed;
Owing to being plugged with conduit hollow taper plug 1 at the bottom nozzle of secondary pouring conduit 2, and be provided with sealing ring 4 between empty taper plug 1 and secondary pouring conduit lower end in the catheter, inserted through when crossing mud 7 under the bottom of secondary pouring conduit 2, make can not enter mud in secondary pouring conduit 2, thus ensure when the perfusion of second coagulation soil, do not have silt particle to be discharged from secondary pouring conduit 2, interlayer is caused between the concrete being mixed in twice perfusion, make secondary pouring concrete eight together with concrete perfusion 6 energy seamless connection first, improve the success rate of pile extension.
S3. the bottom of the secondary pouring conduit 2 with conduit hollow taper plug 1 is inserted in the concrete perfusion first 6 of non-initial set through mud 7;
