Abstract
The invention relates to an engineering test device, and particularly relates to a soil test device. A surface vibrating compaction apparatus for tests for determining the maximum dry density of coarse-grained soil is composed of armrests, a vibrating motor, a motor baseplate, a connecting rod, a breathable tamping plate, a sleeve, a hinged bolt, a testing cylinder, a hinge mount, a hinge pin and a baseplate. The surface vibrating compaction apparatus disclosed by the invention has the advantages that: the apparatus can adapt to different environments; and the apparatus is simple in structure, low in production cost, and convenient and reliable in application and operation.
Description
Technical field
The present invention relates to engineering test facility, particularly soil test equipment.
Background technology
For highway, railway; The airport; Reservoir, dykes and dams and tunnel etc. all need the maximum dry density of local coarse-grained soil is made an experiment to confirm the maximum dry density value of coarse-grained soil before working design, and adopted: a kind of is to be furnished with vibrating motor, electric block, stand and counterweight in the past; Another kind is the vibroplatform method, is fixed on examination bucket and sleeve on the shaking platform, adds counterweight, measures the maximum dry density of coarse-grained soil.
Summary of the invention
The objective of the invention is to: design a kind of simple, convenient, fast, easy to operate and lightweight maximum dry density value test apparatus that is used to measure coarse-grained soil.
Technical scheme of the present invention is: the surface vibration compactor is used in a kind of maximum dry density test of measuring coarse-grained soil; Be made up of handrail, vibrating motor, electric baseboard, connecting rod, ventilative tamping plate, sleeve, hinge bolt, examination tube, hinge seat, bearing pin and base plate, it is characterized in that: the examination jacket casing is contained on the base plate, and sleeve set is on the examination tube; Hinge seat is connected with base thread; Hinge bolt is inserted in hinge seat and penetrates connection with bearing pin, and hinge bolt is used for sleeve and examination tube fixed base plate, and ventilative tamping plate and electric baseboard are welded to connect by 4 connecting rods; On electric baseboard, two handrails are welded on electric baseboard to vibrating motor with bolt.It is characterized in that: described ventilative tamping plate is uniformly distributed with ventilative aperture and ventilating groove is arranged, and external diameter is less than the internal diameter of sleeve and examination tube.
Described ventilative tamping plate is uniformly distributed with ventilative aperture and ventilating groove is arranged, and external diameter is less than the internal diameter of sleeve and examination tube.
Its operating principle and process are: pack the coarse-grained soil that sorts out of needs mensuration into and be made up of in the fit examination tube of lower set sleeve, hinge bolt, examination tube, hinge seat, bearing pin and base plate; The people controls handrail; By examination bucket, handrail,, vibrating motor, electric baseboard, connecting rod and the ventilative tamping plate ventilative tamping plate body of forming the top combination puts into the fit examination bucket of lower set, promptly ventilative tamping plate is pressed on the coarse-grained soil in the examination bucket; Set up the working time of vibrating motor through control apparatus after; Energized, the people controls handrail and promptly controls the fit work of upper group, and control apparatus control vibrating motor was worked in the time of setting up.Concrete experiment rules consult JTC E40-2007 the highway earthwork test rule " " maximum dry density of coarse-grained soil and over coarse grained soil is tested " in 276 pages.
The invention has the advantages that the surface vibration compactor is used in a kind of maximum dry density test of measuring coarse-grained soil, can adapt to various environment; And make simply, easy to operate simple, overcritical to operating personnel, can make an experiment efficiently; Ventilative tamping plate is evenly equipped with ventilative aperture and has ventilating groove, and this has great role to the discharging of the gas between the coarse-grained soil in test, and the maximum dry density value of the coarse-grained soil of mensuration is more accurate like this; This case is in light weight, the loading and unloading convenient transportation.
