Description
Technical field
The utility model relates to fields such as Tunnel Engineering, mining tunnel, particularly a kind of tunnel crack water burst simulated test facility.
Background technology
It is the difficult problem of puzzlement underground works that seepage flow destroys always, especially deep tunnel, water conservancy project tunnel, mining tunnel and seabed tunnel etc., because these engineerings generally are in below the underground water table, add rich water-soluble hole, the influence of complex geological conditions such as water guide tomography, make prominent mud water burst geologic hazard take place often, often cause serious engineering accident.So the caused seepage flow destruction of tunnel excavation disturbance is carried out mechanical property test and analysis, it is an important process that guarantees that tunnel safety, constructing tunnel carry out smoothly.Existing simulation test normally stress field and seepage field is separately carried out test simulation, so often can not reflect real tunnel excavation and water burst process and influence factor and rule, simultaneously also can't observe the water burst path, being difficult to provides more valuable test figure and waterproof construction measure targetedly reliably to design and the construction in tunnel, thereby can not well guarantee safety and the efficient of tunnel construction.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of tunnel crack water burst simulated test facility is provided.This equipment can more real reflection tunnel excavation and influence factor and the rule of water burst process, can also observe the water burst path, obtain the change in time and space in crack, plane and carry out rule, can provide more valuable test figure and the measure of more reliable waterproof construction targetedly to design and the construction in tunnel, thereby can well guarantee safety and the efficient of tunnel construction.
The technical scheme that its technical matters that solves the utility model adopts is, a kind of tunnel crack water burst simulated test facility, its composition is: the test soil body case of rectangular parallelepiped is made of base plate, transparent top board and side plate all around, and the side that the middle part of described top board is provided with circular door closure, top board is provided with the rectangle door closure; Side plate is formed by stacking by load plate and the inner infiltration plate of outside, and the two ends card of side plate has draw-in groove, infiltration plate to fixedly connected with draw-in groove; Adjacent draw-in groove connects by flexible material.
Described test soil body case places the reaction frame of frame shape, is furnished with lifting jack between draw-in groove and the reaction frame, and the bottom of lifting jack is installed on the reaction frame; Base plate is fixedly arranged at the bottom of reaction frame, and the top is equipped with transparent cover plate, and sealing strip is set around the cover inner surface; Lifting jack links to each other with hydraulic power unit.
Be inserted with water inlet pipe on the described reaction frame, the other end of water inlet pipe links to each other with the pressurization water feed apparatus, also is connected with flowmeter, water inlet pipe valve, tensimeter on the water inlet pipe.
The bottom of described test soil body case under circular door closure and rectangle door closure is equipped with rising pipe, and rising pipe is provided with the rising pipe valve, and rising pipe end below is collecting container.
Work engineering of the present utility model and principle are:
Place the soil body by the ratio of similitude configuration in the test soil body case, or adopt undisturbed soil, to simulate different country rock grades.Simultaneously, in the soil body, bury pore pressure gauge, displacement meter, soil pressure cell underground.Hydraulic power unit is controlled lifting jack separately and the soil body in the test soil body case is pressurizeed by load plate and infiltration plate with thrust size separately, to realize the simulation to different surrounding rock pressure.Treat that surrouding rock stress reaches when setting size, open rectangle door closure or circular door closure on the test soil body roof box, so that the different excavation form in tunnel is simulated.Cover rectangle door closure or circular door closure then, cover the cover plate of reaction frame again, make the infiltration chamber that forms a sealing between reaction frame and test soil body case.Again by the pressurization water feed apparatus to infiltration chamber water-filling and reach the hydraulic pressure of setting.
Soil pressure and water pressure all reach need after, extract the load plate of a certain side, this moment, water infiltrated soil body chamber from this direction, by extracting the load plate of diverse location (side) or diverse location combination, can simulate different seepage directions.
In process of the test, pre-buried pore pressure gauge, displacement meter, soil pressure cell are tested pore water pressure, land movement, soil pressure respectively.
Real-time monitored and record by to collecting container can draw percolation flow velocity and seepage flow.
Simultaneously, because top board and cover plate are all transparent, therefore can adopt the digital camera of high pixel that the soil body is taken pictures in test soil body box top, high-speed camera is photographed to the experiment soil body in real time, obtain dynamic image, motion path with clear observation and record soil particle and water obtains the change in time and space in crack, plane and carries out rule.
Again in conjunction with when test given pressure from surrounding rock, the excavation form of tunnel, different seepage direction and the testing tool pore water pressure, land movement, the soil pressure that record can obtain the change in time and space in percolation flow velocity, seepage flow, crack, plane and carry out rule and the mutual relationship of factors such as wall rock condition, underground water, excavation form.
Compared with prior art, income effect of the present utility model is:
Testing equipment of the present utility model can apply different load to the soil body at the trial from different directions, to simulate different pressures from surrounding rock, also can carry out soil body infiltration with different hydraulic pressure from different directions simultaneously, thereby the crack water burst simulation test of tunnel excavation under the coupling of realization stress and seepage flow, can also observe and be recorded to the water burst path, clear distribution and the path of understanding its seepage channel obtains the change in time and space in crack, plane and carries out rule; In conjunction with the soil body that records in real time and current parameter, the influence factor and the rule that can more real analysis obtain tunnel excavation and water burst process, can provide more valuable test figure and the measure of more reliable waterproof construction targetedly to design and the construction in tunnel, thereby can well guarantee safety and the efficient of tunnel construction.
Below in conjunction with concrete the drawings and specific embodiments the utility model is described in further detail.
