Description
Technical field
A kind of pile foundation engineering technique that the utility model belongs in civil engineering, and in particular to multi-functional pile foundation simulation experiment
Case.
Background technology
Recently as the construction of high-rise, high-rise building, pile foundation is because of its high capacity, and the features such as deforming small obtains
It is increasing to pay attention to.Forefathers focus mostly in theoretical research, but as it is assumed that condition is too many, it is sometimes long for same stake,
The foundation pile in same stake footpath, different theories formula obtains bearing capacity and sedimentation differs greatly.In-situ test is due to site condition or machine
The limitation of tool equipment can not be implemented sometimes, and most in-situ test is all that a certain stake carried out in specific place is long, stake
The research in footpath, it is difficult to carry out systematic research to pile foundation, the in-situ test for a clump of piles does not almost have.
Therefore, pile foundation model test research pile foundation of can yet be regarded as is carried out on the basis of model experiment similar theory is met to be had
Efficacious prescriptions method.Zhou Xiaolong has invented a kind of variable element ultra-long pile effective length research simulation chamber (patent No. by research:
ZL201510195754.1), but the problem of the invention does not account for foundation soil modulus of elasticity at piles with different end, also not to soil around pile
Sedimentation with stake end is monitored.After the completion of pile foundation particularly overlength model test of pile, how foundation soil is taken out conveniently
Battery of tests, which, yet under carrying out is not probed into.Current model test, does not account for the change of different foundation pile bottoms pile-end soil substantially
Change, also do not account for the change of the condition such as long, pilespacing of stake in same battery of tests.These are all optimization element task characters in fact,
Reduce the important topic of building settlement otherness.In addition experiment in due to banket wait operate, stake end inevitably departs from
Originally the position set so can bring error so as to cause the change of pilespacing to result of the test.
Utility model content
There is provided a kind of Multifunctional pile base model test in order to overcome the above-mentioned deficiencies of the prior art for the purpose of this utility model
Case, its is simple in construction, simple operation, reusable, and can improve experiment accuracy.
The technical solution adopted in the utility model is:A kind of multi-functional pile foundation simulation chamber, including casing, detachable spiral shell
Silk, adjuster and simulation stake;
The casing is combined by armorplate glass and angle steel, and the front side of casing is switchable door made of tempered glass, steel
Change glass door both sides and be respectively equipped with hinge and latch, two side walls of casing, which are provided with the inside of osculum, osculum, installs filtering
Net, the bottom plate reserving hole of casing simultaneously installs detachable screw;
Spring and displacement transducer built in the adjuster, adjuster embedded are threadedly secured in by what its bottom was provided with
On the detachable screw, the simulation stake is placed on above spring, the external computer of displacement transducer.
Preferably, the door made of tempered glass is marked with horizontal scale line, available for observation foundation soil placement in layers and
Sedimentation.
There is reserving hole on coordinate scale line, coordinate scale line to supply detachable spiral shell preferably, the box bottom is drawn
Silk is fixed.
Door made of tempered glass described in the utility model can be opened, and soil is unloaded for having tested, and described adjuster will by experiment
Ask, inside can place the spring of different-stiffness to simulate pile-end soil modulus of elasticity, and have an embedded screw thread, available for being fixed on
On the detachable screw of bottom plate, displacement transducer is installed in spring bottom, and connects computer real-time data collection.Described can
The formula screw of unloading can be fixed on box bottom by test requirements document.
The beneficial effects of the utility model:
(1) the front side armorplate glass of casing is made openable door and laid out pile with optimizing, it is possible to complete rear in experiment
Just the foundation soil in casing is taken out, when special casing is higher, the advantage of door is more prominent;
(2) being drawn on the front side door made of tempered glass of casing has horizontal scale line, when filled foundation is native, can fill
Compaction in layers is carried out during certain absolute altitude, is so conducive to controlling the compactness of foundation soil, and it is same what is loaded to pile foundation
When observe foundation soil sedimentation;
(3) box bottom, which is drawn, a coordinate scale line, and each coordinate points can be used in fixed screw, adjuster can screw in
On screw, it is such be advantageous in that to simplify lay out pile, reduce influence to clump of piles pilespacing during filled foundation soil;
(4) left and right sidewall of casing leaves osculum, and inside sidewalls are provided with screen pack, with clay, silt etc.
When ground foundation simulation is native, for ground consolidation draining;
(5) adjuster can select different diameter and length as needed, and longer regulation is just selected when stake is long shorter
Device, it is ensured that loading device is loaded to pile body., can be in advance in different positions particularly to there is the situation of long-short pile in a clump of piles
The adjuster of different length is installed, then places thereon pile body;
(6) spring built in adjuster and displacement transducer, choose spring, especially according to the modulus of elasticity of each foundation pile pile-end soil
Exist in place when boulder, solution cavity, there may be "abnormal" situation at indivedual Under Pile ends, the now effect of adjuster
It is most important to feasible simulation Bearing Capacity of Pile Groups character;Displacement transducer connects computer, and every grade of load stake end can be gathered in real time
Sedimentation situation.
