Recoverable prestressing force anti -floating pile, it includes concrete pile body (8), main muscle (10) and enlarged footing (6), be provided with steel reinforcement cage (3) and steel strand wires (4) in its characterized in that concrete pile body (8), the top of concrete pile body (8) is provided with ground tackle (2), the inside central point of enlarged footing (6) puts and is provided with bearing pad piece (5), bearing pad piece (5) are walked around to the intermediate position of steel strand wires (4), two tip of steel strand wires (4) respectively pass one ground tackle (2), steel strand wires (4) overcoat is equipped with PVC sleeve (11). It have the atress effectual, provide bear the weight of dynamic height, characteristics with low costs, remove the convenience, but recycle has reduced the waste of resource.
Description
Technical field
This utility model relates to a kind of recoverable prestressed uplift pile, and it belongs to ground foundation engineering field.
Background technology
Uplift pile refers to that uplift pile refers to be primarily subjected to the stake of vertical uplift load.The range of application of uplift pile is the broadest, has the rock anchorage base etc. in anchoring pile, cable way bridge and cable-stayed bridge used in the pile foundation under transmission line tower foundation, offshore drilling platforms, the pile foundation of high-rise structure, stake static load test all to belong to and uplift pile basis.
Existing uplift pile, it is to be made up of the enlarged footing arranged bottom cylinder concrete pile body, internal arrangement of reinforcement and pile body.It is the bearing capacity making uplift pile can reach structural requirement in coastal soft soil area such as grade, often it is designed into the uplift pile that stake is long, stake footpath is bigger, this uplift pile produces vertical displacement under external force, stress is the most gradually stress, do not play the effect of uplift pile completely, and uplift pile concrete, amount of reinforcement are relatively big, construction cost and difficulty of construction all increase, economical not, applicable.When built exceed service life after can remove, have the higher ratio of reinforcement uplift pile remove difficulty, formed building waste, cause the wasting of resources.
Summary of the invention
This utility model is contemplated to solve above-mentioned technical problem, and the recoverable prestressed uplift pile of one provided, and it has, and the bearing capacity that stressed effect is good, provide is high, the feature of low cost, and it is convenient to remove, recoverable, decreases the waste of resource.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions:
Recoverable prestressed uplift pile, it includes concrete pile body, main muscle and enlarged footing, wherein it is provided with steel reinforcement cage and steel strand wires in concrete pile body, the top of concrete pile body is provided with anchorage, the inner hub location of enlarged footing is provided with pressure-bearing cushion block, pressure-bearing cushion block is walked around in the centre position of steel strand wires, and two ends of steel strand wires respectively through an anchorage, are arranged with plastic bushing outside steel strand wires.
Above-mentioned reinforcement cage structure is as follows: be from top to bottom arranged on the tie hoop in concrete pile body and the spaced ring-type reinforcement stirrup of horizontally set is welded.
A diameter of 1.5-2 times of concrete pile body diameter of above-mentioned enlarged footing.
Above-mentioned main muscle is disposed longitudinally in concrete pile body, and main muscle is welded on the tie hoop of steel reinforcement cage.
Owing to using technique scheme to make this utility model have the advantage that and effect:
The loading characteristic of the frictional force of conventional friction uplift pile the most gradually transmits, and plays the frictional force of stake bottom the most completely.The recoverable prestressed uplift pile of this utility model, the most gradually transmits during stress, and the frictional force of bottom is more much larger than the frictional force on top, it is possible to preferably play the effect of uplift pile.
This utility model uses pre-stress construction can reduce the ratio of reinforcement of reinforcing bar, reduces the consumption of reinforcing bar, and steel strand wires can reclaim after construction completes, cost-effective, and the utilization of resources and environmental conservation are played well effect.
This utility model has bearing capacity height, the feature of low cost that stressed effect is good, provide, and it removes convenient, and recoverable decreases the waste of resource.
