Description
Technical field
The utility model relates to a kind of fixed devices of pile body of the indoor pile-soil model test in indoor model test equipment.
Background technique
It would ordinarily be encountered complicated foundation pit operating condition, such as the influence adjacent to existing building basis in urban construction.Sometimes it needs
The interaction of Supporting Structure deformation caused by excavation of foundation pit and composite foundation is researched and analysed by indoor model test,
But intends pile arrangement in stake clay model there are several difficult points: it is bad in sand to make marks if 1, test is sand with figure, it is inconvenient
Guide pile end position；2, to guarantee that pile body does not glance off during banketing relatively difficult；3, cohesive soil is studied at other people
Model test in, the method that Model Pile is arranged mostly is to excavate hole similar in the diameter of one and stake after the completion of banketing again will
After pile body insertion, then tamp, but when the stake for testing selection is elongated stake, hole excavate will and it is inconvenient, and dig
Native process can make into disturbance with local methods to what is filled in.
In the scientific research of civil engineering, indoor model test is important means and method.Pile-soil interaction
Research is a kind of research type being frequently run onto model test, and the precision of stake position and the verticality of pile body are real in such test
One of successful key factor of guarantee test, during actual tests, the fixing means of pile body will receive the shadow of soil property property
It rings, when especially using elongated stake in test, the fixation of pile body seems more difficult.It is existing to be buried for elongated stake in cohesive soil
If the method for mostly using borehole after first banketing, there are three difficult points for such method: firstly, elongated hole is excavated, there are biggish difficulties
Degree, the precision of stake position and the verticality of pile body are difficult to ensure；Secondly, digging process can impact surrounding soil, finally
When pile body is more, such as 25, in such cases, the larger workload of excavation will affect test progress.In addition to this, right
Less someone of fixing means of pile body refers in the shots soil body such as dry sand, and the fixation of pile body is compared with cohesive soil in the shots soil such as sand
It is more difficult, it is mainly reflected in three convenience: 1, when fixing pile body before banketing, since three native liquids mark it can not
Note, causes pile position deviation larger；2, after stake position determines, the process of banketing will cause pile body offset, and pile body position and verticality are all
It is unable to get guarantee；3, due to the fluid behaviour of shot soil, can not using first banket excavate afterwards by the way of place pile body.Between upper
Reason is stated, is badly in need of studying a kind of fixed to pile body fixation device suitable for the test of indoor pile-soil model, and guarantee it not
Model test progress is influenced, does not influence the process of banketing, while can guarantee the precision and Model Pile pile body of Model Pile position
Verticality.
