Abstract
The invention relates to a triaxial-test soil-sample rubber-membrane rubber band sleeving device and its application method. The device provided by the invention belongs to the technical field of soil test instrument and equipment and is designed to solve the problem that it is hard to manually sleeve a rubber band on a rubber membrane for a triaxial test of a soil sample. The device provided by the invention is mainly composed of a pair of bifurcated steel rods with hand supports and a riveting steel buckle which are both made of alloy steel with high strength and rigidity. As for the bifurcated steel rods with the hand supports, each hand support is an approximate semicircular ring with the radius being about 30mm, the length of each steel rod is about 120mm, the spacing of the steel rod bifurcated opening is about 50mm, and the diameter of the alloy steel is 3mm. The riveting steel buckle is used to rivet the two bifurcated steel rods with the hand supports together. The device provided by the invention has advantages of simple structure, low cost, convenient operation and strong practicality. By the adoption of the device, manpower is saved, and rubber band sleeving time is also saved.
Description
Technical field
The invention belongs to the earthwork test Instrument equipment technical field, be specifically related to a kind of strain control formula triaxial apparatus pressure chamber accessories apparatus and using method thereof, relate in particular to a kind of triaxial test soil sample rubber Membrane cover muscle device and using method thereof.
Background technology
In civil engineering work practice and theoretical research process, for the mechanical characteristics such as intensity, distortion and pore water pressure of measuring soil sample, generally adopt strain control formula triaxial apparatus to carry out correlation test.According to the difference of drainage condition, can be divided into not fixed not Drainage Shear triaxial test (UU), fixed not Drainage Shear triaxial test (CU) and consolidation draining again and cut triaxial test (CD).Strain control formula triaxial apparatus becomes device, tensimeter, zero-position indicator, switch board and annex by testing machine, pressure chamber, constant voltage body and forms.Testing machine is driven by low speed synchromotor, adopts mechanical gear shifted, and the observing and controlling cabinet is made up of tensimeter, zero-position indicator and pressure regulator valve etc.
The pressure chamber of strain control formula triaxial apparatus is the pressure-vessel that holds sample, can bear the hydraulic pressure of 1MPa, it is made up of base and last cover two parts, and the bottom surface has concave station to match with the testing machine lifter plate, test just is placed in the pressure chamber with soil sample, and diameter is 39.1 mm.When the soil sample of cover rubber membrane was installed in the pressure chamber, the lower end will entangle rubber membrane firm on base together with soil sample with bungee, and the upper end will entangle rubber membrane firm on the pressure transmission plate together with soil sample with bungee equally.During the cover bungee, generally need two people's cooperations just can finish, wherein a people is holding up rubber membrane, and another people's both hands firmly strut enough sizes with bungee, and entangles the outer rubber membrane of soil sample.The method of this artificial cover bungee is not only time-consuming but also require great effort; and often also can break bungee; sometimes the bungee cover puts in place, and back four fingers are very difficult therefrom releases; therefore; need the measure of a kind of new cover bungee of invention, carry out the operation of triaxial test soil sample rubber Membrane cover muscle efficiently with convenient.
Summary of the invention
The purpose of this invention is to provide a kind of triaxial test soil sample rubber Membrane cover muscle device, this device not only can be enclosed within bungee on the soil sample that is surrounded by rubber membrane easily, and simple in structure, convenient efficient, time saving and energy saving.
The present invention provides the using method of this device simultaneously.
The technical solution used in the present invention is: triaxial test soil sample rubber Membrane cover muscle device, and mainly to be buckled with the riveted joint steel by the bifurcated steel pole of a pair of band hand support and form, material is the higher alloy steel of strength and stiffness; The bifurcated steel pole of described band hand support, the hand support is the semicircular ring of about 30 mm of radius, and steel pole length is about 120 mm, and steel pole prong spacing is about 50 mm, and the alloy steel diameter is 3 mm; Described rivet steel button, the bifurcated steel pole that two band hands are supportted is riveted together.
Using method of the present invention is: at first bungee is enclosed within on the cover muscle device steel pole of not opening, strut cover muscle device steel pole with a hand then, when bungee struts the soil sample that can be inserted in the rubber membrane parcel, with bungee rubber membrane is entangled firm on the base of triaxial apparatus pressure chamber together with soil sample, the another hand then bungee from the cover muscle device under the strip, extract cover muscle device simultaneously out, use the same method again and bungee is enclosed within the other end of soil sample rubber membrane, soil sample is entangled firm on the pressure transmission plate of triaxial apparatus pressure chamber.
Principle of work of the present invention is: triaxial test soil sample rubber Membrane cover muscle device utilizes lever principle, easily the free-hand bungee that is difficult to strut is strutted suitable size, and be enclosed within easily on the soil sample rubber membrane, simultaneously, because cover muscle device steel pole is smooth, and diameter is little, be easy to from the bungee that packages, extract out, thus the cover muscle work of having finished the triaxial test soil sample of quickness and high efficiency.
The invention has the beneficial effects as follows: triaxial test soil sample rubber Membrane cover muscle device not only can be enclosed within bungee on the soil sample that is surrounded by rubber membrane easily, and simple in structure, with low cost, easy to operate, practical, not only saves time but also save manpower.
Description of drawings
Fig. 1 is triaxial test soil sample rubber Membrane cover muscle device front view of the present invention.
Fig. 2 is triaxial test soil sample rubber Membrane cover muscle device left view of the present invention.
The bifurcated steel pole of marginal data: 1-band hand support; 2-riveted joint steel button.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, triaxial test soil sample rubber Membrane cover muscle device of the present invention is mainly buckled 2 by the bifurcated steel pole 1 of a pair of band hand support with the riveted joint steel and is formed, and material is the higher alloy steel of strength and stiffness; The bifurcated steel pole 1 of described band hand support, the hand support is the semicircular ring of about 30 mm of radius, and steel pole length is about 120 mm, and steel pole prong spacing is about 50 mm, and the alloy steel diameter is 3 mm; Described rivet steel button 2, the bifurcated steel pole 1 that two band hands are supportted is riveted together.
During use, at first bungee is enclosed within on the cover muscle device steel pole of not opening 1, strut cover muscle device steel pole 1 with a hand then, when bungee struts the soil sample that can be inserted in the rubber membrane parcel, with bungee rubber membrane is entangled firm on the base of triaxial apparatus pressure chamber together with soil sample, the another hand then under the strip, is extracted bungee out cover muscle device from the cover muscle device simultaneously, use the same method again and bungee is enclosed within the other end of soil sample rubber membrane, soil sample is entangled firm on the pressure transmission plate of triaxial apparatus pressure chamber.
