Tradition analog simulation plane experimental provision General Requirements simulation Overlying Strata In A Face transport conditions, the inside dimension needing is large, general length all surpasses 3m, when carrying out the relevant simulated experiment of roadway surrounding rock, because tunnel size is little, experimental provision length reaches 2m and just can meet the requirements, so traditional experiment device volume is large, consumption steel are many and cause the whole heavier mobile difficulty of device; Enough analog materials of need to mating formation during experiment fill experiment device inside, cause the waste of material, and need a large amount of manpower and time.Traditional experiment device relies on merely top counterweight or jack pair material to load, there is not charger in horizontal direction, cannot simulate and determine under coefficient of horizontal pressure condition and roadway surrounding rock situation of change during different coefficient of horizontal pressure, make experimental provision limit greatly the simulation to roadway surrounding rock under full-scale condition.
Summary of the invention
Technical problem to be solved in the utility model is the shortcoming that overcomes that above-mentioned traditional analog simulation experimental provision volume is large, consumable material is many, can not side direction loads, provide a kind of reasonable in design, simple in structure, easy and simple to handle, can carry out vertical and tunnel that horizontal direction loads two-dimensional stress simulation plane experimental provision simultaneously.
Solving the problems of the technologies described above adopted technical scheme is: it comprises left column and the right column that is fixed on base both sides, left column, right column top are fixed with crossbeam, crossbeam below is provided with lifting jack and upper force transmitting board, right column inner side is provided with hollow tube bracing frame, on hollow tube bracing frame, be provided with side direction lifting jack and side direction force transmitting board, on side direction force transmitting board, be fixed with orientation lever, it also comprises the channel-section steel protecting for side when die trial paving is filled out.
On the utility model, lifting jack is positioned at top, Pu Tian district.
On the utility model, lifting jack and side direction lifting jack are 3.
The utility model utilizes physical acting force and reacting force principle, has realized the demand that horizontal direction loads.Compare with conventional planar analog simulation experimental provision, that this experimental provision has is reasonable in design, simple in structure, easy and simple to handle, can carry out vertical simultaneously and the advantage such as horizontal direction loading, can be used as analog simulation plane experimental provision, carry out the analog simulation loading experiment under the different coefficient of horizontal pressure conditions in tunnel, carry out the selection of the determining of drift section parameter, drift support type, the simulated experiments such as prediction that roadway deformation destroys.
