Abstract
The utility model discloses a mixing pile foundation pit support structure, which comprises a concrete mixing pile, an anchoring pile and a steel rope, wherein the anchoring pile is located on an axial line after passing through the concrete mixing pile, and is perpendicular to the side of a foundation pit, the steel rope is respectively connected with the concrete mixing pile and the anchoring pile. With the scheme, the mixing pile foundation pit support structure of the utility model is further provided with the anchoring pile on the basis of the concrete mixing pile, and the concrete mixing pile and the anchoring pile are connected through the steel rope. Thus the horizontal force of the mixing pile pressed on the soil can be offset through the tension of the steel rope, thereby improving the forced way of the concrete mixing pile, increasing the overturning resistance of the concrete mixing pile, and simultaneously reducing the cross section width of the mixing pile compared with projects with the same conditions, and saving project expanse.
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)
