The utility model discloses a steel support simulation device in a deep foundation pit construction mechanical model experiment. The steel support simulation device comprises adhering pieces, stress transmission tubes, a sleeve and a spring. The number of the stress transmission tubes is two. The two stress transmission tubes are fixed to the two ends of the spring through the adhering pieces and the other end of each stress transmission tube is provided with one adhering piece. The spring is fixed to the inner portion of the sleeve. A millimeter calibrated scale is arranged in the sleeve and corresponds to the spring in position. The steel supporting simulation device can simulate the steel support supporting and protecting function in the deep foundation pit digging process and measure the stress received by a steel support in the experiment process and an experiment device is simple in structure, low in cost, easy to machine and produce, convenient to operate and accurate in measurement.
Description
Technical field
The utility model relates to Geotechnical Engineering field, and the steel in especially a kind of deep foundation pit construction Mechanical Model Test supports analogue means.
Background technology
At present, steel in Deep foundation Pit excavation Mechanical Model Test supports analogue means, mainly the brief test equipment forming with the materials processing such as iron wire, plastic pipe, can only realize at horizontal loading loading procedure, these Simple steels support that analog machines easily produce flexural deformation or without any strain; Meanwhile, consider that in deep foundation pit construction Mechanical Model Test, steel supports the long term of reusing born load, cause steel to support difficult recovery of distortion that analog machine produces, support suffered stress state thereby cannot truly, effectively simulate steel, result of the test is not very desirable.
Utility model content
The utility model is in order to address the above problem, the steel having proposed in a kind of deep foundation pit construction Mechanical Model Test supports analogue means, this can simulate steel shotcrete support structure stress process in Deep Excavation effectively, have simple in structure, the advantage that test effect is desirable.
To achieve these goals, the utility model adopts following technical scheme:
Steel in deep foundation pit construction Mechanical Model Test supports an analogue means, comprises bonding sheet, stress transfer pipe, sleeve and spring; Wherein, stress transfer pipe has two, and two stress transfer pipes are fixed on both ends of the spring by adhesive sheet, the other end of two stress transfer pipes is equipped with an adhesive sheet, spring is fixed in sleeve, and sleeve inner is provided with a millimeter rule, and spring is corresponding with the position of millimeter rule.
The middle-end of described sleeve is clear glass.
Described sleeve inner top is provided with several decks.
Operating principle of the present utility model is: in deep foundation ditch model testing digging process, steel supports stressed size by measuring camber of spring size, and multiplies each other and obtain with spring constant, and wherein camber of spring size is measured by millimeter rule.
In deep foundation ditch model testing digging process, the barricade or other object that steel are supported in bonding sheet and the model testing at analogue means two ends are fixed as one, along with the continuous excavation of deep foundation ditch, soil body off-load in model testing, cause wall-retaining structure or other structure to foundation ditch inner inclination, thereby make steel support analogue means and bear extruding---the horizontal pressure force of horizontal direction, pressure is delivered to by stress transfer pipe on the spring of sleeve inner, cause spring crimp, spring deflection can be read by the clear glass rule on sleeve.In spring extrusion process, produce elastic force, react on stress transfer pipe, make it produce horizontal thrust, act on barricade or other works, play the supporting role of simulation steel.
The beneficial effects of the utility model are:
This device not only can be simulated steel shotcrete support effect in Deep Excavation, and in can testing experiment process, steel supports suffered stress intensity, and testing equipment is simple in structure, and cost is lower, and easily processing is easy to operate, measures accurately.
Accompanying drawing explanation
Fig. 1 is structure elevation of the present utility model;
Fig. 2 is section of structure of the present utility model.
Wherein, 1, bonding sheet; 2, stress transfer pipe; 3, sleeve; 4, clear glass; 5, spring; 6, millimeter rule; 7, deck.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the steel in a kind of deep foundation pit construction Mechanical Model Test supports analogue means, comprises bonding sheet 1, stress transfer pipe 2, sleeve 3 and spring 5; Wherein, stress transfer pipe 2 has two, and two stress transfer pipes 2 are fixed on spring 5 two ends by adhesive sheet 1, and the other end of stress transfer pipe 2 is equipped with an adhesive sheet 1, and spring 5 is fixed in sleeve 3, and sleeve 3 inside are provided with millimeter rule 6.
The middle-end of sleeve 3 is clear glass 4.
In deep foundation ditch model testing digging process, steel supports stressed size by measuring spring 5 distortion sizes, and obtains with spring 5 multiplication, and its medi-spring 5 distortion sizes are measured by millimeter rule 6.
In deep foundation ditch model testing digging process, the bonding sheet 1 that steel is supported to analogue means two ends is fixed as one with barricade or other object in model testing, along with the continuous excavation of deep foundation ditch, soil body off-load in model testing, cause wall-retaining structure or other structure to foundation ditch inner inclination, thereby make steel support analogue means and bear extruding---the horizontal pressure force of horizontal direction, pressure is delivered to by stress transfer pipe 2 on the spring 5 of sleeve 3 inside, cause spring 5 crimps, spring 5 deflections can be read by the millimeter rule 6 of the clear glass 5 on sleeve 3.In spring 5 extrusion processes, produce elastic force, react on stress transfer pipe 2, make it produce horizontal thrust, act on barricade or other works, play the supporting role of simulation steel.
By reference to the accompanying drawings the specific embodiment of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
