Description
Technical field
The present invention relates to a kind of Geotechnical Engineering physical simulation multifunctional tester that has guide frame.
Background technology
The a lot of scholars of scientific and technological circle think that 21st century will be the century of the great development of the exploitation underground space.Subterranean tunnel is also all being developed and is being used in the development of urban track traffic and city high speed public transport on a large scale, has impelled people to carry out more deep understanding and research to underground ground.The skyscraper fast development trend also needs to find solid deep layer ground basis.Not only in these areas, also have dam, mine, bridge or the like, all these are all impelling people to accelerate mechanical property research to underground ground.
Project of vital and lasting importance, safety first.The development of all these urban construction, traffic, water conservancy, mining industry all be unable to do without the physical property of underground rock mass is studied, and this all needs the rock mass to the construction area at place, carries out the load test of physical model.Lot of domestic and international work all has realized that the importance that mechanical models for soil and rock are tested, and realize such experiment, and key is a research technique.At present, existing a small amount of unit is in development or preparing development mechanical models for soil and rock test unit, but, the device of its development, just two sides from four sides of model that can realize load, when the vertical load plate of its two directions inwardly loads, the problem that also will inevitably occur interfering with each other in the two boards intersection.The method that they adopt is the right angle intersection position at two boards, blocks with canvas or rubber slab, and this can produce two problems, the one, and the problem of sealing, the one, stressed problem.Extruded soil will inevitably outwards squeeze from this position.Rubber slab rigidity value size is inevitable limited, thereby makes rubber slab that bigger projection outwards be arranged.This has overall influenced test accuracy.
Now, along with the scale of Geotechnical Engineering is increasing, under the deeper and deeper situation of the rock stratum degree of depth, the engineering problem that may occur will be complicated more, and will be also more and more higher to the accuracy requirement of ground performance test research.Like this, certainly will produce an urgent demand that the high-precision analog test unit is developed.
Summary of the invention
The present invention is poorly sealed according to the test specimen case of soil mechanics proving installation of the prior art, orthogonal two boards adopts canvas to connect, influence the problem of test accuracy, provide a kind of sealing tight, orthogonal plate does not produce interference, to improve the Geotechnical Engineering physical simulation multifunctional tester that has guide frame of test accuracy.
For achieving the above object, the present invention is achieved through the following technical solutions:
The Geotechnical Engineering physical simulation multifunctional tester that has guide frame, comprise the test specimen case, it is characterized in that, the test specimen case comprises the guide frame of cube shaped as frame of being made up of frame, and six faces of guide frame are respectively arranged with left load plate, right load plate, last load plate, bottom loading plate, the big plate of preceding big plate and back; Preceding big plate is movably connected to form by the panel more than two, and described panel and guide frame more than two flexibly connects.
Wherein, described preceding big plate is provided with the excavation hole.
Wherein, place, excavation hole is equipped with dismountable platelet, and platelet is connected with panel by fixed frame.
Wherein, described panel more than two connects as one.Preferably by gusset and screw the panel more than two being flexibly connected is one, and the mode of flexible connection is easy for installation and removal.
Wherein, the frame of described guide frame removably connects mutually.
Described left load plate, right load plate, last load plate, bottom loading plate can be exerted pressure to it by lifting jack as load plate.
The soil mechanics performance testing device that has guide frame among the present invention, owing to adopted the guide frame among the present invention, make orthogonal load plate in loading stroke, do not produce interference owing to the guiding function of four frames around the load plate, and the sealing of test specimen case is tight, has improved test accuracy.

Fig. 2 is the side view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is the test specimen case front elevation among the present invention;
Embodiment
Further the present invention is further described below in conjunction with embodiment and accompanying drawing.
As Fig. 1-shown in Figure 4,
The Geotechnical Engineering physical simulation multifunctional tester that has guide frame, comprise the test specimen case, the test specimen case comprises guide frame 1, guide frame 1 is removably connected by frame 2 and forms, and six faces of guide frame 1 are respectively arranged with left load plate, right load plate, last load plate, bottom loading plate, the big plate of preceding big plate and back; Preceding big plate is connected to form by the panel more than two 3, and preceding big plate is provided with the excavation hole, and place, excavation hole is equipped with dismountable platelet 5, and platelet 5 and panel 3 connect as one by fixed frame 6 and stove bolt 4, and platelet 5 is removed, and promptly is the excavation hole.Panel 3 more than two flexibly connects by gusset 7 and screw 8 and is one.Panel 3 flexibly connects with guide frame 1.
When testing, soil is put into the test specimen case, compacting successively, and block-by-block installation panel and platelet, fill soil in the test specimen case after, whole panels are installed the sealing of test specimen case can be carried out load test to each load plate; In the process of the test, the design of platelet is convenient pulls down platelet, can observe or take out test soil in process of the test; After test finishes, can earlier platelet be pulled down, dig out the soil in the test specimen case.
