Description
Technical field
The utility model relates to a kind of direct shear apparatus, particularly the stacked radical operators large direct shear apparatus of one.
Background technology
At present, along with the all-round construction of conservation culture, adopt the ecological way such as the solid slope protection of plant, especially Tree root system becomes current research focus at the effect against sliding of small-sized shallow-layer side slope.In shallow failure, adopt Tree root system to carry out the ununified standard of the ecological ways and means reinforced, and the distortion of Tree root system in shallow failure and suffered soil pressure size are temporarily without effective testing equipment, therefore, the shearing strength of the compound soil body that the deformation of root system in different shear surface situation and root and soil form cannot be measured in design and construction.
Summary of the invention
The purpose of this utility model is to solve the distortion of Tree root system in shallow failure and suffered soil pressure size and radical operators shearing strength and the stacked radical operators large direct shear apparatus of one provided.
The stacked radical operators large direct shear apparatus that the utility model provides includes base, several sections of shear box, reaction frame and lifting jack, wherein several sections of shear box superposes combined successively, shear box is bottom fixed on base, several sections of shear box can be connected with reaction frame by fixed head, and lifting jack is located between reaction frame and shear box.
Detachable roller is provided with between the surface of contact that more than shear box bottom several sections of shear box is adjacent, Structure deformation is belonged in shear history, all the other surface of contact are sliding contact, and are provided with fixed orifice, can be fixed connection each other between adjacent shear box.
Shear box is enclosed by poly (methyl methacrylate) plate and forms, and the upper and lower side of shear box is provided with gusset plate.
Gusset plate is that angle steel material is made.
The fixed head connected between shear box and reaction frame is detachable.
The junction of lifting jack and shear box is provided with sensor, for the mensuration of displacement and pulling force.
Lifting jack is motor-driven jack.
The base plate of base is provided with several adjustable diameter through hole, and each hole is used for different-diameter root system and passes.
Use principle of the present utility model:
Because Tree root system belongs to flexible material, therefore, in the situation of different shallow failure faces, the root system distortion that differing heights goes out is inevitable inconsistent.For this reason, by neighbouring shear box surface of contact is set as shear surface, the quantity of surface of contact is equal with the quantity of shear surface.When neighbouring shear box surface of contact is measured as shear surface, this surface of contact is made to be Structure deformation, and the shear box on this surface of contact top is fixed as a whole, the basifacial shear box of this contact is also fixed as a whole, basifacial for this contact shear box and reaction frame are connected to form entirety simultaneously, then the mensuration of relevant parameter is carried out, in like manner, the shear parameters of the different shear box surface of contact of sequentially determining.
The beneficial effects of the utility model:
Shear box employing organic glass combines to enclose with angle steel and forms, and effectively can reduce overall weight; Upper and lower several shear box is set and carries out stack combinations, the deformation of root system at diverse location place during different shear surface can be monitored respectively; Base is provided with drilled base plate, is applicable to the radical operators shear test of different-diameter, position and quantity; Adopt motor-driven jack that loading procedure is remained a constant speed, reduce loading error; Fixed head layering is adopted to be connected between shear box with reaction frame, the inner stress balance of assurance device, and without the need to external support.

Embodiment
Refer to shown in Fig. 1:
The stacked radical operators large direct shear apparatus that the utility model provides includes base 1, four and saves shear box 2, reaction frame 3 and lifting jack 4, wherein four joint shear boxs 2 superpose combined successively, shear box 2 is bottom fixed on base 1, four joint shear boxs 2 are connected with reaction frame 3 by fixed head 5, and lifting jack 4 is located between reaction frame 3 and shear box 2.
Shear box more than 2 three bottom saves between the adjacent surface of contact of shear box 2 and is provided with detachable roller 6, and in shear history, belong to Structure deformation, all the other are sliding contact, and are provided with fixed orifice 7, can be fixed connection each other between adjacent shear box 2.
Shear box 2 is enclosed by poly (methyl methacrylate) plate and forms, and the upper and lower side of shear box 2 is provided with gusset plate 8.
Gusset plate 8 is made for angle steel material.
The fixed head 5 connected between shear box 2 and reaction frame 3 is detachable.
