The invention provides a waterproof structure of a multi-layer mobile loading beam; the loading beam is used in a loading system for simulating the soil pressure in a laboratory; a plurality of layers of loading beams are distributed in the vertical direction; each loading beam can move back and forth; and the plurality of layers of loading beams can move relative to each other; a waterproof layers are respectively arranged on the top surface, the left surface and the right surface of each loading beam; the waterproof layers are formed by water stopping bars. According to the waterproof structure, the clearance among the loading beams and the clearance between the loading beam and the wall are filled by a plurality of water stopping bars no matter how the loading beams move; in this way, the water penetration is avoided effectively.
Description
Technical field
The present invention relates to a kind of waterproof construction of multilayer motion loading beam, belong to field of civil engineering.
Background technology
In civil engineering work, usually to study the pressure distribution in the native medium, the problem that need to solve on many engineerings all with soil layer in pressure distribution relevant, for example stability of slope problem, the native interphase interaction problem of stake and bearing capacity of pile foundation problem etc.But at present common research means is for to study through the small scale model test; But when there is native medium in the object of simulation; Gravity becomes a difficult physical quantity with simulation; And gravity is Fundamentals that cause the soil body and structure stress deformation and failure, its consolidation settlement, all is directly to be produced by gravity to the soil lateral pressure of structure etc.This is difficult to simulation in the model test of small scale, this native medium that just needs vast scale is as subjects, and vast scale rock-soil layer load application is carried out the soil pressure simulation.In simulation, need use loading beam, and loading beam is usually destroyed by the water in the soil layer.Because loading beam need move at work, surface of contact between the interlayer surface of contact of loading beam and loading beam and the side wall is carried out waterproof need adopt waterproof constructions different when being in static state with it.
Summary of the invention
The technical matters that the present invention will solve is to provide a kind of waterproof construction of multilayer motion loading beam, and it can prevent effectively that sealing infiltrates, and increases the service life.
In order to solve the problems of the technologies described above; The waterproof construction of multilayer motion loading beam provided by the invention; Said loading beam is used in the loading system of in the testing laboratory soil pressure being simulated, and said loading beam vertically multilayer distributes, and said every loading beam can seesaw; But and relative motion between the multilayer loading beam, the end face of said every loading beam, left surface and right flank are provided with water barrier.
Preferably; Said loading system is installed in the test pit, is provided with test soil in the said test pit, and said loading system comprises that an end is installed in the loading actuator on the test pit wall; Said loading actuator vertically multilayer distributes; Every layer loads actuator is that the even distribution of along continuous straight runs is a plurality of, and the other end of said loading actuator is connected with the trailing flank of loading beam through transmission rod, and the number of plies of said loading beam is identical with the number of plies that loads actuator; All corresponding with test each soil layer in the soil, the place ahead of said loading beam is that said test is native.
Preferably; Said water barrier is made up of sealing rod; The sealing rod of said loading beam end face is arranged the end face that is paved with loading beam along the length direction of loading beam; The sealing rod of said loading beam left surface is arranged the left surface that is paved with loading beam along the direction parallel with side wall, and the sealing rod of said loading beam right flank is arranged the right flank that is paved with loading beam along the direction parallel with side wall.
The waterproof construction of multilayer motion loading beam of the present invention, no matter how the multilayer loading beam moves, and fill by many sealing rods in the gap between gap between the loading beam and loading beam and the body of wall, can effectively prevent the infiltration of sealing.

The structural representation that Fig. 2 distributes for loading beam multilayer of the present invention.
Fig. 3 is the axonometric drawing of single loading beam among the present invention.
Embodiment
The waterproof construction of multilayer motion loading beam as depicted in figs. 1 and 2, loading beam 6 are used in the loading system of in the testing laboratory soil pressure being simulated, and loading system is installed in the test pit 1; Be provided with test soil 2 in the test pit 1; Loading system comprises that an end is installed in the loading actuator 3 on the test pit wall, loads actuator 3 multilayer distribution vertically, and every layer loads actuator 3 is that evenly distribution is a plurality of for along continuous straight runs; The other end that loads actuator 3 is connected with the trailing flank of loading beam 6 through transmission rod 5; Loading beam 6 vertically multilayer distributes, and the number of plies of loading beam 6 is identical with the number of plies that loads actuator 3, and is all corresponding with each soil layer of testing in native 2; The place ahead of loading beam 6 is test soil 2; Every loading beam 6 can seesaw, but and relative motion between the multilayer loading beam 6, the end face of every loading beam 6, left surface and right flank are provided with water barrier.
Like Fig. 2 and 3; Water barrier is by sealing rod 41; 42 form; The sealing rod 41 of loading beam 6 end faces is arranged the end face that is paved with loading beam along the length direction of loading beam 6, and the sealing rod 42 of loading beam left surface is along arranging the left surface that is paved with loading beam with side wall 11 parallel directions, and the sealing rod 42 of loading beam right flank is along arranging the right flank that is paved with loading beam with side wall 11 parallel directions.
As shown in Figure 1; During loading system work, guarantee that at first soil 2 promotions are not tested in the position of each layer loading beam 6, then every layer of loading beam 6 loading that loads actuator 3 through 5 pairs of these layers of transmission rod of this layer; Loading beam 6 travels forward and promotes corresponding soil layer; Make that the distortion of this soil layer is excessive and destroy that 6 pairs of pressure to this soil layer of loading beam are exactly the passive earth pressure of this soil layer; If every layer loads the loading beam 6 of actuator 3 through 5 pairs of this layers of transmission rod of this layer and unloads, this layer loading beam 6 promoted by corresponding soil layer backward, is out of shape excessive and destroys until this soil layer, and this soil layer is exactly the active earth pressure of this soil layer to the pressure of loading beam 6.
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 the loading beam 6, loading beam 6 and the body of wall 11, can effectively prevent the infiltration of sealing.As long as and sealing rod possesses certain water-proof function, need not to use the material of high life, can effectively save cost.
