Abstract
The utility model discloses a mixing pile foundation pit supporting structure, which comprises a concrete mixing pile, an anchorage pile and a steel strand, wherein the anchorage pile is arranged on an axis which passes through the concrete mixing pile and is vertical to the edge of a foundation pit; and the steel strand is respectively connected with the concrete mixing pile and the anchorage pile. Above-mentioned scheme, the utility model discloses a mixing pile underground structure on concrete mixing pile basis, has increased the anchorage stake, and concrete mixing pile, anchorage stake pass through the steel strand cable and connect. The horizontal force of the top of the mixing pile on the soil body is offset by the pulling force of the steel cable, the stress form of the concrete mixing pile is improved, the anti-overturning capacity of the concrete mixing pile is improved, meanwhile, the cross section width of the mixing pile can be reduced compared with that of the engineering under the same condition, and the engineering cost is saved.
Description
Technical field
The utility model relates to the deep foundation pit supporting structure in a kind of building operations, a kind of stirring pile pit supporting construction of more specifically saying so.
Background technology
In the method for pattern foundation pit supporting structure, soil nailing and composite soil nailing are used commonplace, and expense is also cheaper, if but can't adopt soil nailing or composite soil nailing because soil property reason and foundation depth are big the time, generally adopt deep-mixed pile supporting and protection structure.Existing agitation pile supporting and protection structure is the concrete pile on the foundation ditch limit of arranging, and can prevent to cheat subsiding of limit earth so on the one hand when digging pit, and can prevent to cheat wall infiltration in the hole on the other hand.Because above-mentioned agitation pile supporting and protection structure is the gravity by agitation pile self keeps the stable of side slope, the horizontal force action bottom offset that withstands on the soil body like this is excessive, causes piling wall integral body to topple easily.
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of agitation pile supporting and protection structure of agitation pile more stable and stronger, and it is excessive and cause piling wall integral body to topple to prevent that stake from withstanding on the horizontal force action bottom offset of the soil body.
For achieving the above object, the utility model by the following technical solutions: a kind of stirring pile pit supporting construction, it comprises concrete agitation pile, anchorage stake, steel strand cable, described anchorage stake is on concrete agitation pile and the axis vertical with the foundation ditch limit; Described steel strand cable is connected with concrete agitation pile, anchorage stake respectively.
Foundation ditch limit one side of described concrete agitation pile upper end is implanted with the band armored concrete slab, and the top of described concrete agitation pile and band armored concrete slab is provided with the contact beam that bears down on one, described steel strand cable with coagulate native agitation pile and get in touch beam by bearing down on one and be connected.Described steel strand cable preferably is provided with the PVC sleeve pipe outward.
Adopt such scheme, stirring pile pit supporting construction of the present utility model on concrete agitation pile basis, has increased the anchorage stake, and concrete agitation pile, anchorage stake connect by the steel strand cable.Agitation pile withstands on the horizontal force of the soil body like this, pulling force by the steel strand cable is offset, and has improved the stress form of concrete agitation pile, has improved concrete agitation pile resistance to capsizing, can reduce the breadth of section of agitation pile simultaneously than the engineering of equal conditions, save engineering cost.
Description of drawings
Fig. 1 is the schematic diagram of stirring pile pit supporting construction of the present utility model.
Among the figure, 1-concrete agitation pile, the stake of 2-anchorage, 3-steel strand cable, 4-foundation ditch limit, 5-is with armored concrete slab, the 6-contact beam that bears down on one, 7-PVC sleeve pipe.
The specific embodiment
As shown in Figure 1, stirring pile pit supporting construction of the present utility model, it is included in concrete agitation pile 1, anchorage stake 2, steel strand cable 3, and described anchorage stake 2 is on concrete agitation pile 1 and the axis vertical with foundation ditch limit 4.
Described steel strand cable 3 respectively with coagulate native agitation pile 1, anchorage stake 2 is connected.For guaranteeing the pulling force of steel strand cable 3, in practical operation, can tighten up steel strand cable 3 usefulness Chain blocks.
As improvement, foundation ditch limit 4 one sides of described concrete agitation pile 1 upper end are implanted with band armored concrete slab 5, the top of described concrete agitation pile 1 and band armored concrete slab 5 is provided with the contact beam 6 that bears down on one, and described steel strand cable 3 is got in touch beam 6 with concrete agitation pile 1 and is connected by bearing down on one.
Be the convenience in practical operation, will pass the temporary road of construction, can earlier PVC sleeve pipe 7 be embedded in the road, then as long as steel strand cable 3 is passed PVC sleeve pipe 7 as steel strand cable 3.
Claims (3)
