Description
Technical field
The utility model belongs to the environmental geotechnical technical field, is specifically related to a kind of anti-force type large-size municipal solid wastes compressing tester.
Background technology
Municipal solid wastes is in people's daily life or for the city daily life provides the solid waste that produces in the activity of service, if municipal solid wastes is not handled, will cause serious harm to environment.At present, sanitary landfill is to handle the topmost method of municipal solid wastes.In the landfill process, sedimentation will take place in solid waste under deadweight or overlying burden effect, sedimentation before closing can increase the capacity of landfill yard, but excessive sedimentation and non-uniform settling will make the pipeline of landfill yard inside destroy, and cause that landfill yard internal drainage and exhaust are obstructed; Excessive sedimentation takes place in the back if close, and will make covering layer of landfill site geomembrane generation drawing crack destroy.So the sedimentation of landfill yard is one of main geotechnological problem of relating to of landfill yard.
In order to calculate the sedimentation of landfill yard, must adopt the compression deflection characteristics of compression test further investigation municipal solid wastes.Because the complicated component of municipal solid wastes contains the great number of organic matters composition, and contains more large-size particle, at present traditional geotechnological compressing tester (internal diameter: 6.18cm, height 2cm) size is too little, can't carry out compression test; Even municipal solid wastes is carried out fragmentation, adopt traditional geotechnological compressing tester to carry out compression test, also can't reflect the real compression deflection characteristics of municipal solid wastes.
Summary of the invention
The purpose of this utility model is to propose a kind of anti-force type large-size municipal solid wastes compressing tester.
The anti-force type large-size municipal solid wastes compressing tester that the utility model proposes, be made up of top board 1, column 2, measure one's own ability ring 3, pressure piston 4, compression container 5, permeable stone 6, pallet 7, lifting jack 8, base 9, displacement meter 10, connecting pipe 11 and percolate collector 12, its structure as depicted in figs. 1 and 2.Wherein, top board 1, column 2 and base 9 are formed a reaction frame system, and column 2 one ends connect base 9 by bolt, and the other end connects top board 1 by bolt; Ring 3 one ends of measuring one's own ability connect top board 1 by bolt, and the other end connects pressure piston 4 by bolt, and pressure piston 4 is positioned at compression container 5 tops, and pressure piston 4 is connected to form by the compact disk 14 of connecting link 13 and bottom, is provided with osculum in the middle of the compact disk 14; Compression container 5 is positioned at pallet 7 tops, and the upper and lower permeable stone 6 that is equipped with of compression container 5 is provided with osculum around the bottom; Pallet 7 sidewalls are provided with osculum; Lifting jack 8 is positioned at pallet 7 belows, and is fixed in base 9 tops; Displacement meter 10 is made up of magnetic support 15 and test instrumentation 16, and magnetic support 15 is fixed on the column 2, and test instrumentation 16 is fixed in compression container 5 one sides; Connecting pipe 11 1 ends connect pallet 7 sidewall osculums, and the other end connects percolate collector 12.
In the utility model, the ring 3 of measuring one's own ability is connected to form by steel loop and dial gauge.
In the utility model, above 1/3 position, compression container 5 bottom surfaces is provided with stirrup, and test instrumentation 16 is fixed in this stirrup top.
In the utility model, column 2 is the 2-4 root.
In the utility model, compact disk 14 diameters of pressure piston 4 should to guarantee in the compression test process, not produce friction resistance between compression piston 4 and the compression container 5 less than the internal diameter of compression container 5, guarantee the accuracy of testing.
In the utility model, higher around the pallet 7 than middle, the convenient percolate of from compression container, discharging of collecting.
The course of work of the present utility model is as follows:
In compression container 5, fill municipal solid wastes as sample, a permeable stone 6 is respectively put at bottom and top at sample, on permeable stone 6, lay filter paper, allow the chassis of pressure piston 4 contact with top permeable stone 6, because the pressure piston 4 and the ring 3 of measuring one's own ability all are to be fixed on the top board 1, the chassis of pressure piston 4 can not move, and shakes lifting jack 8 load applications, pallet 7 and compression container 5 will move upward, and make municipal solid wastes generation compression deformation.Because reaction frame is a self-balancing system, the jacking pressure of lifting jack 8 determines that by the deflection of the ring 3 of measuring one's own ability the distortion of the ring 3 of measuring one's own ability is read by the dial gauge that is contained in the ring of measuring one's own ability, and determines the jacking pressure of lifting jack by the rigidity reduction coefficient; The distortion of municipal solid wastes is calculated by displacement meter 10 test compression containers 5 ascending amounts; The percolate that produces in the municipal solid wastes compression process is to be discharged on the pallet 7 by compression container 5 bottom discharge holes, by the osculum of pallet 7 sidewalls, through connecting pipe 11, is pooled in the percolate collector 12 then.
The beneficial effects of the utility model:
The utility model has satisfied the compressibility that existing instrument can't be tested the municipal solid wastes sample that contains large-size particle, can reasonably estimate the municipal solid wastes compression property.
