Description
Technical field
The present invention relates to a kind of multilayer Motion loading beam with waterproof construction, belong to field of civil engineering.
Background technology
In civil engineering work, usually to study the pressure distribution in native medium, in many engineerings, need the problem of solution all relevant with the pressure distribution in soil layer, such as stability of slope problem, mutual effect of the pile and soil problem and bearing capacity of pile foundation problem etc.But at present common research means is for to study by small-scale model test, but when there is native medium in the object of simulation, gravity becomes a physical quantity that is relatively difficult to simulation, and gravity is Fundamentals that cause the soil body and structure stress deformation and failure, its consolidation settlement, soil lateral pressure of structure etc. is all directly produced by gravity.This is difficult to simulation in the model test of small scale, and this just needs the native medium of vast scale as subjects, and vast scale rock-soil layer load application is carried out to soil pressure simulation.In simulation, need to use loading beam, and loading beam is usually destroyed by the water in soil layer.Because loading beam needs to move at work, surface of contact between the interlayer contact face of loading beam and loading beam and side wall is carried out to waterproof and need to adopt the waterproof construction different when the static state with it.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of multilayer Motion loading beam with waterproof construction, and it can infiltrate by effectively anti-sealing, increases the service life.
In order to solve the problems of the technologies described above, the multilayer Motion loading beam with waterproof construction provided by the invention, described loading beam is used in the loading system of in testing laboratory, soil pressure being simulated, described loading beam is Multi-layers distributing vertically, every described loading beam can seesaw, and between multilayer loading beam, can be movable relatively, the end face of every described loading beam, left surface and right flank arrange water barrier.
Preferably, described loading system is arranged in a test pit, in described test pit, be provided with test soil, described loading system comprises that one end is arranged on the loading actuator on test pit wall, described loading actuator is Multi-layers distributing vertically, every layer loads actuator to be that along continuous straight runs is uniformly distributed a plurality of, the other end of described loading actuator is connected with the trailing flank of loading beam by transmission rod, the number of plies of described loading beam is identical with the number of plies that loads actuator, all corresponding with each soil layer in test soil, the place ahead of described loading beam is described test soil.
Preferably, described water barrier is comprised of sealing rod, the sealing rod of described loading beam end face arranges along the length direction of loading beam the end face that is paved with loading beam, the sealing rod of described loading beam left surface is arranged the left surface that is paved with loading beam along the direction parallel with side wall, the sealing rod of described loading beam right flank is arranged the right flank that is paved with loading beam along the direction parallel with side wall.
The multilayer Motion loading beam with waterproof construction of the present invention, no matter how multilayer loading beam moves, and fill by many sealing rods in the gap between the gap between loading beam and loading beam and body of wall, infiltration that can effectively anti-sealing.
Accompanying drawing explanation
Fig. 1 tests the schematic diagram of the indoor loading system that soil pressure is simulated in the present invention.
Fig. 2 is the structural representation of loading beam Multi-layers distributing of the present invention.
Fig. 3 is the axonometric drawing of single loading beam in the present invention.
Embodiment
The multilayer Motion loading beam as depicted in figs. 1 and 2 with waterproof construction, loading beam 6 is used in the loading system of in testing laboratory, soil pressure being simulated, loading system is arranged in a test pit 1, in test pit 1, be provided with test soil 2, loading system comprises that one end is arranged on the loading actuator 3 on test pit wall, load vertically Multi-layers distributing of actuator 3, every layer of loading actuator 3 is a plurality of for along continuous straight runs is uniformly distributed, the other end that loads actuator 3 is connected with the trailing flank of loading beam 6 by transmission rod 5, loading beam 6 is Multi-layers distributing vertically, the number of plies of loading beam 6 is identical with the number of plies that loads actuator 3, all corresponding with each soil layer in test soil 2, the place ahead of loading beam 6 is test soil 2, every loading beam 6 can seesaw, and can be movable relatively between multilayer loading beam 6, the end face of every loading beam 6, left surface and right flank respectively arrange water barrier.
As Fig. 2 and 3, water barrier is by sealing rod 41,42 form, the sealing rod 41 of loading beam 6 end faces arranges along the length direction of loading beam 6 end face that is paved with loading beam, the sealing rod 42 of loading beam left surface is arranged the left surface that is paved with loading beam along the direction parallel with side wall 11, the sealing rod 42 of loading beam right flank is arranged the right flank that is paved with loading beam along the direction parallel with side wall 11.
As shown in Figure 1, during loading system work, first the position that guarantees each layer of loading beam 6 is not promoted by test soil 2, then every layer loads actuator 3 by loading beam 6 loadings of 5 pairs of these layers of transmission rod of this layer, loading beam 6 travels forward and promotes corresponding soil layer, make the distortion of this soil layer excessive and destroy, 6 pairs of the loading beams pressure to this soil layer, is exactly the passive earth pressure of this soil layer; If every layer loads actuator 3 by loading beam 6 unloadings of 5 pairs of these layers of transmission rod of this layer, this layer of loading beam 6 promoted backward by corresponding soil layer, until this soil layer distortion is excessive, destroys, and the pressure of this soil layer to loading beam 6, is exactly the active earth pressure of this soil layer.
In the present invention, as shown in Figure 2, no matter how multilayer loading beam 6 moves, and fill by many sealing rods in the gap between the gap between loading beam 6, loading beam 6 and body of wall 11, infiltration that can effectively anti-sealing.And as long as sealing rod possesses certain water-proof function, without the material that uses the high life, can effectively save cost.
