Abstract
The utility model discloses a grouting pile provided with double layers of tensile bars. Inner-circle reinforcing steel bars are arranged in the middle of the grouting pipe and fixed through an inner reinforcing steel bar cage, outer-circle reinforcing steel bars are arranged on the outer circle of the grouting pile and fixed through an outer reinforcing steel bar cage, and reinforcing steel bars used for fixing the distance between the inner reinforcing steel bar cage and the outer reinforcing steel bar cage are welded between the inner reinforcing steel bar cage and the outer reinforcing steel bar cage. Tensile force borne by the grouting pile in the range of the pile length is relatively uniform, and force borne by the overall pile is more uniform and more reasonable. The number of tensile reinforcing steel bars around the pile is reduced correspondingly, and the reinforcing steel bars around the pile body bear a small part of the tensile force and mainly play a role in controlling cracks. The inner-circle reinforcing steel bars are bound while the outer-circle reinforcing steel bars are bound, construction is convenient, operation is easy, and construction quality is guaranteed.

Background technology
In recent years, the improving constantly of the development of national economy and people's living standard is all in the development that constantly promotes urban construction.Emerging in large numbers of high level and super highrise building, the basis is embedding more and more darker, the pure basement part of building as the square formula of the functions such as garage simultaneously, podium or relatively independent underground structure are (such as sinkage type structure, underground garage, subway, underground store etc.) development and utilization more and more.Thus, the waterproof of underground structure and anti-floating problem become increasingly conspicuous, and the basement anti-floating problem that buried depth is larger just seems particularly important.Because the existence of buoyancy can produce destruction to underground structure and superstructure: the basement bottom board protuberance, cause coal seam floor failure, underground structure integral body is inhomogeneous floats, and causes the inclination of bean column node place cracking and coal seam floor failure and building etc.The anti-floating problem that how to solve underground structure has become a problem that often faces at present, causes engineer's extensive concern.
At present, uplift pile being set is for the most widely used a kind of solution of underground structure anti-floating problem in engineering design.The uplift resistance design of uplift pile is taken by pile body and the frictional force of soil and the smaller value of pile body tension bearing capacity, generally speaking by the frictional force control of pile body with soil.The stake footpath is less, and larger with the surface area of volume pile body, then frictional force is also larger.In addition, obvious to the Concentrated load of base plate if the single pile uplift resistance is excessive if the basis is raft foundation, strengthen or change the form of structure of base plate for the part of bearing the base plate that this uplift resistance must take this moment, and cost is further increased.So uplift pile should select generally that stake footpath is less, the corresponding less stake of single pile uplift resistance is gathered.Long should as far as possible being controlled in the single-unit pile length scope of stake of uplift pile, the uplift resistance loss that can reduce like this pile extension expense and avoid causing owing to pile extension is insecure.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of castinplace pile that double-deck tension muscle is set is provided, and is a kind of uplift pile that can in-site pouring, and it is simple and convenient to construct.
For achieving the above object, the utility model adopts following technical proposals:
A kind of castinplace pile that double-deck tension muscle is set, in the middle of it and outer ring arranges respectively inner ring reinforcing bar and outer ring reinforcing bar, and both are fixed by interior reinforcing cage and outer reinforcing cage respectively, and welding is used for the fixing reinforcing bar of distance between the two between described interior reinforcing cage and the outer reinforcing cage.
The core of described castinplace pile is provided with vertical muscle, can share the vertical tension of larger proportion, thereby makes the corresponding minimizing of tensile reinforcement around the stake, avoids the stake stressed excessive crack that causes of tensile reinforcement on every side.
Distance between the stake heart of described inner ring reinforcing bar and castinplace pile is 1/2 radius of castinplace pile.
Described interior reinforcing cage and outer reinforcing cage are respectively: along inner ring reinforcing bar and outer ring reinforcing bar vertically, the some circle stirrups that arrange every 0.5m.
