Description
Technical field
The invention belongs to engineering construction testing equipment or device technique field, be specifically related to be used for the test platform of simulated formation distortion.
Background technology
The geologic hazard that stratum deformation causes (like ground fissure, land subsidence etc.) is very big to the harm of Architectural Equipments such as building, bridge, tunnel, pipeline.Set up the stratum deformation simulator stand, through the certain stratum deformation of the artificial manufacturing of stratum deformation simulator stand, for the deformation behaviour of the different geologic condition sub-surfaces of research, the different punishment method of study tour sub-surface deformation ability is very necessary.
Adopt the test of small scale testing equipment about the research of this problem at present, data error is bigger more.The test platform of large scale research stratum deformation problem is actually rare; The patent No. is that 200410026128.1 Chinese patent discloses a kind of large-scale test platform; This platform is a test panel utilizing the movable settlement plate of many equilateral triangles to be combined into; The movable settlement plate of each equilateral triangle is located the platen bearing and the electric-hand driven two-purpose lifting jack of below and is supported through being arranged on its summit (node just); Utilize the up-down of lifting jack to realize the up-down of test platform node, like this, the test platform that is spliced into by the movable settlement plate of equilateral triangle just is easy to simulate various distortion; Can utilize this distortion to come the simulated formation distortion, carry out the stratum deformation simulation test.
Because the movable settlement plate of these equilateral triangles is directly to be placed on the platen bearing; Simultaneously in order to simulate distortion; Be reserved with little clearance each other at the movable settlement plate of equilateral triangle; But the horizontal direction at the movable settlement plate of equilateral triangle is not provided with locating device, carries out under the effect of soil internal stress complicated in the process in test, and the movable settlement plate of some equilateral triangles can produce and move horizontally sometimes; Can produce the phenomenon that drops downwards when serious, influence the authenticity of test findings even can cause unexpected injury.Test soil from the slot leakage testing table lifting jack jacking district below test panel between the movable settlement plate of equilateral triangle in order to prevent simultaneously; On the seam of the movable settlement plate of equilateral triangle, be provided with some simple cover plates in the process of the test; But because these cover plates do not have detent mechanism; In process of the test, move owing to cover plate, cause testing soil and leak downwards through regular meeting.
Summary of the invention
Technical matters to be solved by this invention is to overcome the shortcoming that above-mentioned test platform support panel is easy to generate big displacement in process of the test, the edge leaks soil, and the stratum deformation analogue test platform support panel of better, the safe side seal of a kind of reasonable in design, good airproof performance, globality is provided.
The technical scheme that solves the problems of the technologies described above is: it is made up of at least ten module unit panels, and wherein a module unit panel connects through connector with the bight of an adjacent module unit panel, is provided with seal between a module unit panel and the adjacent module unit panel.
Unit panel of the present invention is: the edge of plate is processed with limiting stand in the above, and the lower surface edge of plate is provided with side plate in the above, is provided with bearing block between a side plate and the adjacent side plate; Seal is arranged on the limiting stand.
The lower surface of top panel of the present invention is provided with strengthening part.
Strengthening part of the present invention is stiffening plate and/or reinforced pipe.
The bearing block arranged outside in the bight at unit panel of the present invention has safety door hook.
A module unit panel of the present invention with the mode that the bight of an adjacent module unit panel uses connector to connect is: pass a module unit panel with connector and connect with the safety door hook in an adjacent module unit panel bight.
Seal of the present invention comprises that overlap joint is at intermediate seal bar on the limiting stand of two adjacent unit panels and the edge sealing strip 4 that is arranged on the limiting stand of edge unit panel.
Top panel of the present invention is a steel facing.
Safety door hook and the connector that pass safety door hook of the present invention through being arranged on the unit panel bight connects each unit panel of node place, avoided making the technical matters that the displacement that the horizontal direction generation is bigger at the node place of individual elements panel is perhaps dropped because the acting force that soil deformation produces causes the individual elements panel significantly to move horizontally; The present invention is provided with limiting stand on the unit panel edge, the limiting stand between two adjacent panels forms stopper slot, and seal is set in stopper slot; Through seal plug envelope, can prevent effectively that soil particle from leaking from slit between unit panel downwards, stopper slot can prevent seal overmigrate in process of the test; After adopting rigid seal; Seal also can prevent between two adjacent panels too near, make that also the globality of whole front panel is better, security is higher; The lower surface middle part that the present invention also is employed in unit panel is provided with strengthening part; Can reinforced panel whole load-bearing capacity, its deformation is reduced, improved the measuring accuracy of whole test platform simultaneously; Security also is greatly improved, and has further strengthened the load-bearing capacity of support panel.Top panel of the present invention adopts steel material, makes top panel be convenient to processing more, and rigidity is improved.
