The heap-typed jumbo-size compression tester comprises an upright post, a pressurizing weight, a base seat, a pressure piston, a compression vessel, a displacement meter, permeable stones, a salver, a connecting pipe, and a leachate gathering device. The upright post is positioned at a corner of the base seat; the pressure piston is composed of an upper compressed disk, a joint lever and a lower compressed disk which are connected in turn; the pressurizing weight passes through the upright post through a hole thereof, and the pressurizing weight is positioned above the upper compressed disk of the pressure piston; the compression vessel is positioned above the salver, and the permeable stones are respectively arranged above and under the compression vessel; the displacement meter is composed of a magnetic base and a test instrumentation; the salver is fixed above the base seat, and a drain hole is arranged on the lateral wall of the salver; one end of the connecting pipe is connected with the drain hole on the lateral wall of the salver, and the other end is connected with the leachate gathering device. The utility model satisfies the compressibility for the test sample of the urban solid wastes containing jumbo-size particles that cannot be tested by the existing apparatus, and reasonably evaluates the compression characteristic of the urban solid wastes.
Description
Technical field
The utility model belongs to the environmental geotechnical technical field, is specifically related to a kind of preloading formula large scale 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 landfills 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 differential settlement 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 provide a kind of preloading formula large scale municipal solid wastes compressing tester.
The preloading formula large scale municipal solid wastes compressing tester that the utility model proposes, be made up of column 1, compression weight 2, base 3, pressure piston 4, compression container 5, displacement meter 6, permeable stone 7, pallet 8, tube connector 9 and percolate collector 10, its structure as depicted in figs. 1 and 2.Column 1 is positioned at the corner of base 3, and column 1 one ends connect base 3 by bolt; Pressure piston 4 is connected to form successively by last compact disk 12, connecting rod 11 and lower compression dish 13, is provided with osculum in the middle of the lower compression dish 13; Compression weight 2 is formed by stacking by some steel plates, and its corner has hole, and compression weight 2 is passed column 1 by the hole on it, and is positioned at last compact disk 12 tops of pressure piston 4, is applied on the municipal solid wastes as xial feed; Compression container 5 is positioned at pallet 8 tops, is provided with osculum around the bottom, and the upper and lower in the compression container 5 respectively is provided with permeable stone 7; Displacement meter 6 is made up of magnetic support 14 and test instrumentation 15, and magnetic support 14 is fixed on the column 1, and test instrumentation 15 is positioned at lower compression dish 13 tops; Pallet 8 is fixed in base 3 tops, and its sidewall is provided with osculum; Tube connector 9 one ends link to each other with pallet 8 sidewall osculums, and the other end connects percolate collector 10.
In the utility model, column 1 is the 3-4 root.
In the utility model, above 1/3 position, compression container 5 bottom surfaces is provided with stirrup.
In the utility model, be covered with permeable hole on the permeable stone 7.
In the utility model, lower compression dish 13 diameters of pressure piston 4 should to guarantee in the compression test process, not produce frictional resistance between pressure 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 8 than middle, the convenient percolate of from compression container 5, discharging of collecting.
The course of work of the present utility model is as follows:
In compression container 5, fill municipal solid wastes, respectively put a permeable stone 7, on permeable stone 7, lay filter paper at the bottom and the top of sample as sample; Allow the lower compression dish of pressure piston 4 contact with top permeable stone 7, the compression weight 2 that has hole is all around passed column 1, directly be placed on the last compact disk of pressure piston 4, column 1 plays the effect of guiding for compression weight, avoid run-off the straight, the weight of compression weight 2 passes to municipal solid wastes by compression piston 4, make municipal solid wastes generation compression, can calculate the pressure that acts on the municipal solid wastes according to the weight of compression weight 2 and the load-bearing area of municipal solid wastes sample; The distortion of municipal solid wastes is calculated by the deflection of the lower compression dish 13 of displacement meter 6 test pressure pistons 4.Obtain the stressed size and the deflection of municipal solid wastes, just can determine the compression deflection characteristics of municipal solid wastes.The percolate that produces in the municipal solid wastes compression process is to be discharged on the pallet 8 by compression container 5 bottom discharge holes, by the osculum of pallet 8 sidewalls, through tube connector 9, is pooled in the percolate collector 10 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.
