The linking beam of campshed and rear campshed；Rotary churning pile is equipped between the preceding campshed and rear campshed, is equipped in the rotary churning pile as its positioning
Steel strand wires.
The utility model in traditional Double-row Piles Support before and after be additionally arranged rotary churning pile between campshed, can be well by waist
Beam, front and rear campshed and inter-pile soil body link together, and reduce the Internal forces of preceding campshed and rear campshed, significantly increase branch
The overall stiffness of shield provides larger drag, is conducive to the Deformation control of foundation pit, and reduce pile shaft material dosage, improves economical
Benefit；Secondly, using steel strand wires localization method, the method for improving jet grouting pile construction at pile body has saved the duration, has provided standard
True positioning method improves the construction precision of deep layer rotating spraying stake, when avoiding jet grouting pile construction due to direction determine it is unstable
The construction error brought and the intensity for influencing pile body around foundation pit, reduce the injury to front and rear pile body of row pile in traditional supporting.
Furtherly, the steel strand wires of the utility model are anchored by the anchor being set on rear campshed；The anchoring
Device includes anchor disk and anchor end plate.
It further says, the preceding campshed of the utility model is equipped with the waist rail for connecting the preceding campshed, parallel to set
The lower section of campshed capping beam before being placed in；One end of rotary churning pile is connect with waist rail, and the other end is connect with rear campshed；The slip casting of rotary churning pile
Material is cement mortar, and the ratio of mud is 0.4~0.45, and cement-sand ratio is 0.5~1.0.
Furtherly, preceding campshed is the deposited reinforced concrete pile of circular cross-section；Campshed is the reinforcing bar of circular cross-section afterwards
Cast-in-place concrete pile；The horizontal layout of preceding campshed and rear campshed is plum blossom array arrangement.
Advantageous effect：Compared with prior art, it is the advantages of the utility model：The overall stiffness of the Double-row-piles Structure compared with
Greatly, internal force is smaller, Supporting Structure deformation is small, without the supporting members such as setting support anchor in follow-up Excavation Process, reduces
Support pile material utilization amount greatly facilitates the construction of earth excavation and underground structure in hole, significantly improves construction efficiency,
The duration has been saved, has reduced construction cost, applicable base pit engineering range is wider.

Specific embodiment
The technical solution of the utility model is described further with reference to embodiment.
As shown in Figures 1 and 2, pile body of the present invention is equipped with the Retaining Structure with Double-row Piles of rotary churning pile, including preceding campshed 1, sets
The rear campshed capping beam 4 of campshed 2 after rear campshed 2 in preceding 1 side of campshed, the preceding campshed capping beam 3 of the preceding campshed 1 of connection, connection
And the linking beam 5 of the preceding campshed 1 of connection and rear campshed 2, wherein, preceding campshed 1 is the deposited reinforced concrete pile of circular cross-section, preceding
Campshed 1 is equipped with the waist rail 9 for connecting the preceding campshed 1, the lower section of campshed capping beam 3, rear campshed 2 before being arranged in parallel in
