Description
Technical field
The present invention relates to it is a kind of suitable for pile-soil interaction test detachable concrete balancing weight experimental rig and
Its manufacturing method.
Background technique
Currently, the simulating vibration table test for carrying out the researchs such as pile-soil interaction is research engineering shock resistance and breaks
One of the important means of bad mechanism, by the concern of domestic and international academia and engineering field.But it is limited to effectively holding for shake table
Loading capability, large scale structure can only be tested with scaled model.Therefore, to enable model test to be truly reflected original as far as possible
The power character of type, it is necessary to consider the Physical similarity between model and prototype, this relates to the likelihood ratio value of each physical quantity
Problem.For a long time, manual quality's law of similitude based on the foundation of Bockingham Buckingham theorem is once in engineering model shaketalle test
Middle extensive use simultaneously adopts so far.In view of when carrying out shaking-table test, since model and prototype are at together
In one gravitational field, therefore acceleration of gravity is equal.It is limited by the constraint condition, fully meeting for model likelihood just becomes
It is extremely difficult, the similar of acceleration of gravity can be generally met by the method for additional bob-weight, imitates gravitational effect and inertia
The deficiency answered is compensated.And then how clump weight is fixed in Model Pile by crucial be just changed into of problem, one of which is thought
Road is to consider to extend the main reinforcement of Model Pile into concrete balancing weight, and also carry out certain arrangement of reinforcement in clump weight.This method
Although clump weight and Model Pile can be fixed together well, if there is the scaled model stake of more same ratios, then
Every Model Pile requires to connect clump weight with this method, causes to waste.In the pile-soil interaction test using reduced scale stake
This problem will be faced, it is therefore necessary to be considered as economical rationality concrete balancing weight experimental rig come to Model Pile into
Row self weight compensation.
Summary of the invention
The present invention improves the above problem, i.e., the technical problem to be solved by the present invention is to existing development stake soil phases
Clump weight needs to repeat modeling in the simulating vibration table test of the researchs such as interaction.
Specific embodiments of the present invention are: a kind of detachable concrete balancing weight suitable for pile-soil interaction test
Experimental rig, which is characterized in that including the square module being enclosed by multiple panels, the square module center is fixed with
The tube body being placed in inside square template, the bottom of the pipe closing.
Further, the square module includes cope plate and lower template, is fixed between the cope plate and lower template
The square shape side plate being enclosed, the upper end of tube body are concordant with cope plate.
Further, the material of the tube body is PVC.
Further, sandy soil are filled in the tube body.
The invention also includes a kind of detachable concrete matcheds that manufacture is tested suitable for pile-soil interaction as described above
The method of pouring weight experimental rig, which is characterized in that specifically includes the following steps:
(1) a piece internal diameter of the insertion tube body equal with Model Pile diameter at middle at the top of the square module of casting concrete,
Tube body does not penetrate square module, i.e., tube body upper horizontal plane and cope plate either flush and is shorter in length than side template height.
(2) it to prevent tube body to be subject to crushing in concreting process, is filled up and is compacted with sand in tube body.
(3) the cuboid coagulation for deducting one section of cylindrical body is made in casting concrete inside square module and outside tube body
Native clump weight.
(4) it after the completion of concrete curing, removes square module and sand is poured out or dug out, detachable concrete weight coating
Block completes.
Compared with prior art, the invention has the following advantages: experiment forming module of the invention can facilitate system
There is slot can carry out in more scaled model stakes in proportion at detachable concrete balancing weight, in the middle part of concrete balancing weight
The concrete balancing weight installation is carried out during pile-soil interaction test, is tested when being changed to other Model Piles in proportion
When, which can be disassembled from master mould stake and be mounted in new model stake, obtain concrete balancing weight
To duplicate utilization, reduces experimental cost and avoid material waste.
