Abstract
The utility model discloses a kind of pile body overload protection pile cover of composite foundation; outer pile cover and interior pile protection including mutual cooperation; the interior pile protection outer wall is arranged with multistage yielding component from upper; make a concession component and yielding action occurs when load exceedes arranges value; the outer pile cover, which is overlapped on, to be made a concession on component, and containment vessel is additionally provided with the outside of the interior pile protection.This configuration has improved composite foundation integrated carrying ability.
Description
Technical field
The utility model belongs to civil engineering field, and in particular to a kind of composite foundation pile body overload protection pile cover.
Background technology
Composite foundation refers to that subsoil part soil body during basement process is strengthened, or is replaced, or in day
Reinforcement material is set in right ground, stabilization zone is by subsoil and reinforcement artificial foundation dimerous, according to ground
The different of middle reinforcement direction can be divided into geosynthetic-reinforced mattress composite foundation and vertical reinforcement composite foundation again；And vertically strengthen
The common two kinds of failure modes of bluk recombination ground：One kind is that pile body destroys first, and then the overall destruction of composite foundation occurs, another
Kind is that inter-pile soil destroys and then the overall destruction of composite foundation occurs first.The first failure mode is very fast due to developing, and is most
For a kind of failure mode of danger.Current pile body does not have defencive function in overload, so that destroy inter-pile soil when occurring
Bearing capacity can not play completely.
The content of the invention
The utility model is aiming at the deficiencies in the prior art, there is provided a kind of to improve answering for composite foundation integrated carrying ability
Close ground pile body overload protection pile cover.
To achieve these goals, the pile body overload protection pile cover of a kind of composite foundation designed by the utility model, its
It is characterized in that：Outer pile cover and interior pile protection including mutual cooperation, the interior pile protection outer wall move back from the upper multistage that is arranged with
Allow component, make a concession component yielding occurs when load exceedes arranges value and act, the outer pile cover is overlapped on yielding component, described
Containment vessel is additionally provided with the outside of interior pile protection.
Further, the yielding component is made up of some yielding units, and the yielding unit is in same one-level by between 60 ° of grades
It is uniform in load action lower stress away from arrangement, stress concentration phenomenon will not be produced.
Further, the yielding component is provided with 2 ~ 6 grades, it is possible to achieve multistage regulation.
Yet further, the spacing for making a concession the adjacent the superior and the subordinate of component can be set according to being actually needed, and be traditionally arranged to be
More than 2cm to produce enough yielding amounts.
Yet further, the yielding unit of component between the superior and the subordinate of making a concession is staggeredly arranged.After avoiding cutting
Latch blocks outer pile cover.
Yet further, the containment vessel and interior pile protection are formed in one structure, and the containment vessel and interior pile protection outer wall
U-shape structure is collectively forming, the yielding component is located inside U-shape structure.Interior pile protection is provided with containment vessel to exclude composite foundation
The yielding displacement of bed course pile cover outside particulate blockage in deformation adjustment.
Yet further, the yielding unit is cuts latch, and when undertaking load and exceeding arranges value, generation fragility is broken
It is bad, pile body is protected in time.
Yet further, the installation neck that latch is cut for installing, the cutting are provided with the interior pile protection outer wall
Latch one end is fixed using be hinged, is needed to stir cutting latch during use, is made it from closure state to deployed condition.The other end is used
In overlapping outer pile cover, set installation neck that cutting latch can be protected to be not damaged by transport and assembling process.
The utility model has the advantage of：
Design is multistage to make a concession component, and yielding action occurs when load exceedes arranges value, can prevent for the yielding component
Composite foundation pile body destroys because carrying excessive in the course of the work, avoids pile body from destroying first and causes what ground integrally destroyed
Pattern occurs.Meanwhile by setting the larger composite foundation bed course of relative rigidity, default stake soil is can reach by repeatedly adjusting
Stress ratio, give full play to inter-pile soil bearing capacity.

In figure：Outer pile cover 1, interior encapsulation 2, make a concession component 3, neck 4, containment vessel 5.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
The pile body overload protection pile cover of composite foundation as depicted, include the outer pile cover 1 and interior pile protection 2 of mutual cooperation,
The interior outer wall of pile protection 2 is arranged with multistage yielding component 3 from upper, and outer pile cover 1, which is overlapped on, to be made a concession on component 3, and the interior outside of pile protection 2 is also
It is provided with containment vessel 5.Containment vessel 5 is excluding the yielding position of composite foundation bed course pile cover 1 outside particulate blockage in deformation adjustment
Move.
Make a concession component 3 to be made up of some yielding units, in order to reduce stress concentration phenomenon, make a concession unit and pressed in same one-level
60 ° are equally spaced in the interior surrounding of encapsulation 2.Make a concession component 3 and be provided with 2 ~ 6 grades, the spacing of adjacent the superior and the subordinate is 2cm.It is used as this
The preferred structure of utility model, as preferred structure of the present utility model, described interior pile protection and outer pile cover are using cutting unit
Overlapped as unit is made a concession.Other overlapping modes can use the modes such as wedge-shaped snap ring, oval snap ring.Cut unit
Latch is specially cut, the installation neck 4 that latch is cut for installing is provided with the interior outer wall of pile protection 2, latch one end is cut and adopts
Need to stir cutting latch be hinged fixation, during use, make it from closure state to deployed condition.The other end is used to overlap stud
Cap 1, set installation neck 4 that cutting latch can be protected to transport and be not damaged by assembling process.Pottery can be used by cutting latch
The fragile materials such as porcelain rod, pig iron rod make.To avoid the latch after cutting from blocking outer pile cover, cutting latch between the superior and the subordinate is equal
It is staggeredly arranged.
Containment vessel and interior pile protection are formed in one structure in the utility model, and the containment vessel and interior pile protection outer wall are common
U-shape structure is formed, the yielding component 3 is located inside U-shape structure.
During work, the outer top cover of pile cover 1, which undertakes bed course load and passed to, cuts latch 3, when the load that cutting latch 3 is born
When reaching setting value, cut latch and cut, outer pile cover 1 sinks, and reduces stake soil difference in height, is finally reached and set by multistage regulation
Fixed stress ratio, while the effectiveness of pile body and soil is played, improve the bearing capacity of composite foundation.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not done any formal
Limitation, it is any be familiar with any modification of technical staff's made within spirit of the present utility model and principle of the present utility model,
Equivalent variations and improvement etc., it should be included within the scope of protection of the utility model.
