Description
Technical field：
The utility model is related to a kind of middle weathering geology contrary sequence method stand column pile more particularly to a kind of inverse works of middle weathering geology
Method concrete filled steel tube stand column pile.
Background technology：
When carrying out reverse construction in middle weathering geology, steel pipe post stake serves not only as vertical branch when reverse construction
Support, and as the supporting member of basement, the steel pipe post stake used when reverse construction at present is being cut the earth especially
When carrying out catalase, static(al) explosion or mechanical shock fractured rock no matter are used, opposition stanchion is all easy and causes to disturb, pole
Big there are the risks that stand column pile is destroyed, and cause stand column pile depression of bearing force.
Utility model content：
A kind of construction is simple is provided the purpose of the utility model is to overcome the deficiency of above-mentioned prior art, material obtains
It is convenient, the duration is saved, securely and reliably, construction quality is easily guaranteed that, be can effectively avoid catalase opposition stanchion and is generated unfavorable shadow
It rings, ensures the middle weathering geology contrary sequence method concrete filled steel tube stand column pile of engineering smoothly implemented.
The purpose of this utility model can be reached by following measure：A kind of middle weathering geology contrary sequence method steel tube concrete
Native stand column pile comprising stake holes, stake holes is interior to be equipped with steel pipe post stake, it is characterised in that has poured concrete in steel pipe post stake
Plastic film layers, the big 400mm of diameter of the aperture ratio steel pipe post stake of stake holes, stake holes and steel are wrapped up in column, steel pipe post stake outside
Gap between tube column stake is filled with the supple buffer layer being made of microlith of 30-50mm grain sizes.
In order to further realize the purpose of this utility model, the steel pipe post stake outside is in raft foundation bottom elevation line
The above package plastic film layers, the gap between stake holes and steel pipe post stake is filled with to be made of microlith of 30-50mm grain sizes
Supple buffer layer, the gap between the steel pipe post stake below of raft foundation bottom elevation line and stake holes has poured concrete
Layer.
The utility model can generate following good effect compared with the prior art：The utility model is a kind of band flexible buffer
The concrete filled steel tube stand column pile of construction, wraps up plastic film on the outside of steel pipe post stake, at the same steel pipe post stake and stake holes it
Between filled with 30-50mm grain sizes microliths, form the flexible buffer construction of steel pipe post stake, it is ensured that apply carrying out contrary sequence method
When work catalase, disturbance is not generated to concrete filled steel tube stand column pile and destroyed, ensure that of concrete filled steel tube stand column pile itself
Quality and bearing capacity protect steel pipe post stake.The utility model construction is simple, it is convenient that material obtains, and saves the duration, peace
It is complete reliable, while construction quality is easily guaranteed that, can effectively avoid catalase opposition stanchion and has an adverse effect, ensures engineering
Smoothly implement.
Description of the drawings：
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model；
Fig. 2 is the vertical view of Fig. 1；
Fig. 3 is the structural schematic diagram of the another embodiment of the utility model.
Specific implementation mode：It elaborates below in conjunction with the accompanying drawings to the preferred forms of the utility model：
Embodiment 1：A kind of middle weathering geology contrary sequence method concrete filled steel tube stand column pile（Referring to Fig. 1, Fig. 2）Comprising stake

Plastic film layers 4, the big 400mm of diameter of the aperture ratio steel pipe post stake 2 of stake holes 1, the sky between stake holes 1 and steel pipe post stake 2
Gap is filled with the supple buffer layer 5 being made of microlith of 30-50mm grain sizes.
Its construction method is as follows：Plastic film 4 is wrapped up in 2 outside of steel pipe post stake, coagulation is poured in steel pipe post stake 2
Soil fills out 30-50mm grain sizes microlith in 2 outside gap of steel pipe post stake, flexible buffer construction is formed, when ensureing fragmented rock body
Vibrations steel pipe post stake is not affected greatly.
Embodiment 2：A kind of middle weathering geology contrary sequence method concrete filled steel tube stand column pile（Referring to Fig. 3）Comprising stake holes 1,
It is equipped with steel pipe post stake 2 in stake holes 1, concrete column 3, the aperture ratio steel pipe post stake 2 of stake holes 1 have been poured in steel pipe post stake 2
The big 400mm of diameter, plastic film layers 4, stake holes 1 and steel are wrapped up in the outside of steel pipe post stake 2 of 6 or more raft foundation bottom elevation line
Gap between tube column stake 2 is filled with the supple buffer layer 5 being made of microlith of 30-50mm grain sizes, raft foundation bottom mark
Gap between the 6 steel pipe post stake 2 below of high line and stake holes 1 has poured concrete layer 7.
Its construction method is as follows：The casting concrete inside and outside steel pipe post stake 2, casting concrete height is in raft plate base
Plinth bottom elevation line 6 hereinafter, after the concrete initial set poured under raft foundation bottom elevation line 6, at raft foundation bottom elevation line 6 with
On the outside of steel pipe post stake 2 wrap up plastic film 4, casting concrete in steel pipe post stake 2 is empty in 2 outside of steel pipe post stake
Gap fills out 30-50mm grain sizes microlith, flexible buffer construction is formed, to ensure that vibrations when fragmented rock body do not make steel pipe post stake
At larger impact.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
