The T shape stake web of the epimere stake of described binodal T shape stake and hypomere stake is longitudinally embedded with the prestress wire as main muscle without edge of a wing end one side.
In the epimere stake of described binodal T shape stake and hypomere stake web, be embedded with shearing resistance net sheet.
Described agitation pile overlap joint thickness is 15～25 ㎝.
The anhydrous mud of the above part agitation pile in the foundation ditch bottom surface of described agitation pile in foundation ditch.
Described shaped steel built-in fitting comprises pile extension angle steel, anti-shear steel plate bar, connects steel plate and anchor bar, described anti-shear steel plate bar length is coupled between pile extension angle steel to weldering, described connection steel plate short weldering is coupled between pile extension angle steel, the pile extension angle steel upper end of one side is lower than the pile extension angle steel of opposite side, and the weldering of described pile extension angle steel lower end is associated with anchor bar.
A kind of T shape stake providing according to the utility model and the structure of agitation pile combination supporting compared with prior art tool have the following advantages:
1, T section stake bending resistance is strong especially, and reinforcing bar and concrete are low-consuming, adds pile spacing large, and stake number is few, and cost significantly reduces.
2, the agitation pile that arch is arranged can effectively form soil arch, and soil pressure is delivered on soldier pile, can solve again sealing leakproof problem simultaneously, and supporting and protection structure is safe and reliable.
3, soldier pile adopts epimere stake and the reverse pile extension technology of hypomere stake, can make an arrangement of reinforcement mate with bending moment envelope diagram, and significantly saving steel, improves bending rigidity, reduces distortion.

The specific embodiment
Referring to Fig. 1 to Fig. 5, a kind of T shape stake providing at the utility model and agitation pile combined support structure, comprise binodal T shape stake 1, agitation pile 2, grit 3 and support 5, described binodal T shape stake 1 comprises epimere stake 11 and hypomere stake 12, epimere stake 11 and the reverse pile extension of hypomere stake 12 certain depth under foundation ditch.The chain form structure that described agitation pile 2 is lap connection.Binodal T shape stake 1 inserts in the crossing figure of eight agitation pile 2 of two rows, and described grit 3 is coupled to the top of binodal T shape stake 1 or leans on the top of foundation ditch one side.The stake of T shape can divide transportation, the lifting of the convenient stake of two joints, and oppositely pile extension can make the bending resistance direction of stake mate with the bending moment envelope diagram of soldier pile; Continuous chain structure makes the anti-permeability performance of agitation pile good, domes can form good native arching action simultaneously, effectively transmit soil pressure, and space length between supporting piles can be expanded, thereby give full play to the large advantage of T shape soldier pile bending resistance, the cost of soldier pile is reduced; The crossing figure of eight agitation pile total length of two rows arranges, and is convenient to soldier pile and plants stake, and soldier pile is delivered to soil pressure in support by grit.In the present embodiment, grit is located at soldier pile top.
Referring to Fig. 1 to Fig. 3, in the above-described embodiment providing at the utility model, it is dark that described agitation pile 2 is positioned at the dark stake being greater than outside foundation ditch of stake of foundation ditch.Agitation pile outside foundation ditch transmits active earth pressure, and active earth pressure only has in the lower subrange in more than foundation ditch and hole, therefore without elongated setting; Agitation pile in foundation ditch transmits passive earth pressure, must arrange in hole part at the end, but consider piling technological requirement, needs total length piling, only cheats the following part whitewashing in the end.
Referring to Fig. 1, Fig. 5, in the above-described embodiment providing at the utility model, epimere stake 11 lower ends of described binodal T shape stake and hypomere stake 12 epimeres are embedded with welded connection between 4, two shaped steel built-in fittings of shaped steel built-in fitting.Shaped steel built-in fitting manufacturing dimension is accurate, and welded connection is convenient, and Transfer of Shear performance is good, the good integrity of embedded part and stake.
Referring to Fig. 4, in the above-described embodiment providing at the utility model, epimere stake 1 and the hypomere stake 2 of the stake of described binodal T shape all adopt prestress wire 5 as main muscle, and main muscle is longitudinally embedded in T shape stake web end one side.The edge of a wing of T section is as the pressure zone of bending resistance component, reasonable stress, and therefore in a side, burying main muscle underground is conducive to bending resistance.
