Description
Technical field
The utility model relates to construction equipment field, and specifically the bearing capacity of foundation soil such as building, structure is not enough, and prestressed pile need be adopted to meet a kind of prestressed pile with augers of foundation bearing capacity requirement.
Background technology
At building field, when the bearing capacity of foundation soil such as building, structure is not enough, prestressed pile generally need be adopted to meet foundation bearing capacity requirement.In work progress, often there is following situation: 1, prestressed pile does not go down in prestressed pile in the market, forces to suppress even to occur broken pile; 2, prestressed pile enters the rock degree of depth and does not reach; 3, the time of driving piles is long, and efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of prestressed pile with augers, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
With a prestressed pile for augers, comprise a bar, promote pipe, promote sleeve pipe, screw rod and augers; Described stake bar is hollow structure, promotes pipe lower end and inserts stake bar top, and promotes to be provided with flexible member between pipe end cap and stake rod end head; Described screw rod is located in a bar, and pushing set pipe box is located at outside screw rod, and pushing set inside pipe wall is provided with the screw thread matched with screw rod, and the upper end promoting pipe box is fixedly connected with the lower end promoting pipe, and described promotion sleeve pipe is provided with thrust bearing; Described augers is located at below a bar, and screw rod lower end connects augers.
As further program of the utility model: described flexible member is spring.
As the utility model further scheme: described thrust bearing totally 2, be located at the top and bottom promoting sleeve pipe respectively.
As the utility model further scheme: described augers is provided with unilateral bearing, and screw rod connects augers by unilateral bearing.
Compared with prior art, the beneficial effects of the utility model are: 1, the prestressed pile of this band augers can pierce lithosphere easily, ensure that prestressed pile pierces the degree of depth of lithosphere; 2, the prestressed pile of this band augers can pierce lithosphere easily, saves the piling time, improves piling efficiency; 3, the prestressed pile of this band augers is not easy to break a bar, and screw rod and miscellaneous part can take out and reuse in addition.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 6, in the utility model embodiment, a kind of prestressed pile with augers, comprises a bar 1, promotes pipe 3, promotes sleeve pipe 4, screw rod 5 and augers 6; Described stake bar 1 is hollow structure, promotes pipe 3 lower end and inserts stake bar 1 top, and promotes to be provided with flexible member 2 between pipe 3 end cap and stake bar 1 termination, and preferably, described flexible member 2 is spring, and flexible member 2 is for promoting the reset of pipe 3; Described screw rod 5 is located in a bar 1, promoting sleeve pipe 4 is set in outside screw rod 5, and promotion sleeve pipe 4 inwall is provided with the screw thread matched with screw rod 5, the upper end promoting pipe box 4 is fixedly connected with the lower end promoting pipe 3, described promotion sleeve pipe 4 is provided with thrust bearing 7, preferably, described thrust bearing 7 totally 2, be located at the top and bottom promoting sleeve pipe 4 respectively, promote pipe 3 and act on promotion pipe box 4, make it move at vertical direction along stake bar 1 inside, when promotion pipe box 4 moves, drive screw rod 5 to rotate; Described augers 6 is located at below a bar 1, screw rod 5 lower end connects augers 6, when screw rod 5 rotates, augers 6 is driven to rotate, described augers 6 is provided with unilateral bearing 8, screw rod 5 connects augers 6 by unilateral bearing 8, and the effect of unilateral bearing 8 ensures that augers 6 only rotates along a direction.
Operating principle of the present utility model is: the prestressed pile of described band augers, piling process in, when pile driver drop hammer get to promote pipe 3 time, promote pipe 3 act on promote pipe box 4, it is made to move along stake bar 1 inside at vertical direction, when promotion pipe box 4 moves, screw rod 5 is driven to rotate, when screw rod 5 rotates, augers 6 is driven to rotate, time pile driver drops hammer and rises, promotion pipe 3 pops into position by flexible member 2, and a workflow completes.When pile driver drop hammer again fall time, carry out second time workflow.So repeatedly, prestressed pile just can be always downward, pierces lithosphere.
The prestressed pile of described band augers can pierce lithosphere easily, ensure that prestressed pile pierces the degree of depth of lithosphere; The prestressed pile of described band augers can pierce lithosphere easily, saves the piling time, improves piling efficiency; The prestressed pile of described band augers is not easy to break a bar, and screw rod and miscellaneous part can take out and reuse in addition.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this manual is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should by manual integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
