Description
Technical field
The utility model relates to drilled pile perfusion piling technique field, particularly relates to a kind of drilled pile secondary pouring pile making device used when the midway failure of drilled pile perfusion pile.
Background technology
Adopt in catheter perfusion underwater concrete construction process at bored pile; due to when concrete work performance index is not up to standard and workability is poor; often there will be the concrete poured in conduit no longer to flow because segregation causes coarse aggregate to be piled up; cause perfusion operation to be forced to interrupt, cause pile breaking phenomenon.When there is broken pile, normally adopt and descend steel pile casting to broken pile position in the borehole, the mud in boring is drained with pump, artificial chisel proceeds second coagulation soil and builds after going out fresh concrete surface again, there is the high and long in time limit defect of construction cost in this processing method, constantly, the mud in hole cannot be pumped if run into infiltration in boring, the second coagulation soil carried out is built and just be there will be interlayer, causes pile extension failure.
Utility model content
(1) technical problem that will solve
The purpose of this utility model is to provide a kind of drilled pile secondary pouring pile making device, easily occurs the technical problem of pile extension failure to solve drilled pile secondary pouring in prior art.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of drilled pile secondary pouring pile making device, comprise secondary pouring conduit, be connected to the conduit hollow taper plug of described secondary pouring conduit bottom nozzle and be connected to the lower funnel of described secondary pouring catheter tip mouth, described conduit hollow taper plug is the pyramidal structure of hollow, and the bottom of described secondary pouring conduit can be inserted in first in concrete perfusion through the mud in drilling pouring pile hole by described conduit hollow taper plug.
Preferably, described conduit hollow taper plug is tightly connected by the bottom nozzle of sealing ring and described secondary pouring conduit.
(3) beneficial effect
Drilled pile secondary pouring pile making device of the present utility model improves underwater concrete because of plugging and interrupts carrying out the success rate of secondary pile extension perfusion, technique is simple, processing ease, equipment cost less investment, pile extension success rate is high, solves drilled pile secondary pouring in prior art and easily occurs the technical problem of pile extension failure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the drilled pile secondary pouring pile making device of the utility model embodiment.
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, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
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;
Distance between the end face of the bottom nozzle of secondary pouring conduit 2 and first concrete perfusion 6 is 0.8 meter ~ 1.2 meters, in the present embodiment, is preferably 1 meter.
S4. funnel 3 under the top ports of secondary pouring conduit 2 is installed, by lower funnel 3 by secondary pouring concrete eight along secondary pouring conduit 2 catheter wall uniformly continous be filled in secondary pouring conduit 2, after secondary pouring concrete eight is full of secondary pouring conduit 2, stop perfusion, then, secondary pouring conduit 2 is upwards promoted, conduit hollow taper plug 1 is come off from the bottom of secondary pouring conduit 2;
The distance upwards promoted by secondary pouring conduit is 8 centimetres ~ 12 centimetres, in the present embodiment, is preferably 10 centimetres.
S5. continue to pour into secondary pouring concrete eight in secondary pouring conduit 2 by lower funnel 3, until pile filling concrete completes.
Drilled pile secondary pouring pile making device of the present utility model improves underwater concrete because of plugging and interrupts carrying out the success rate of secondary pile extension perfusion, technique is simple, processing ease, equipment cost less investment, pile extension success rate is high, solves drilled pile secondary pouring in prior art and easily occurs the technical problem of pile extension failure.
Embodiment of the present utility model provides for the purpose of example and description, and is not exhaustively or by the utility model be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present utility model and practical application are better described, and enables those of ordinary skill in the art understand the utility model thus design the various embodiments with various amendment being suitable for special-purpose.
