Description

Pouring asphalt concrete multifunction test and shaped device
Technical field
The invention belongs to the experimental facilities that water conservancy and hydropower construction work pouring asphalt concrete is tested in the laboratory, particularly a kind of pouring asphalt concrete multifunction test and shaped device.
Background technology
The forming method that only has the compaction type bituminous concrete in existing hydraulic asphalt concrete testing regulations is for the not relevant concrete device of the moulding of pouring asphalt concrete.But at present more take pouring asphalt concrete as the antiseepage body in the Hydraulic and Hydro-Power Engineering of building.The porosity that can not guarantee in the laboratory hydraulic asphalt concrete test specimen of same batch is consistent, and the every test data of indoor pouring asphalt concrete of test is accurate not, has influence on construction quality.
Summary of the invention
The object of the present invention is to provide a kind of pouring asphalt concrete multifunction test and shaped device, it is rational in infrastructure, and is simple to operate, convenient reading, can improve the accuracy of indoor pouring asphalt concrete test index, for construction provides science, foundation accurately.
The object of the present invention is achieved like this: a kind of pouring asphalt concrete multifunction test and shaped device, affixed column on base, affixed the back up pad in the upper end of column, coordinate in the screw of upper backup pad setting and top is installed with the screw mandrel of rotary handle, the screw mandrel end that is positioned at upper backup pad below is installed with pressure transducer, affixed the keeper plate of steel in the bottom of pressure transducer; The fixed support of adjustable position is installed on column, its contact of the deformation-sensor that is fixedly mounted with on fixed support matches with the end face of keeper plate of steel, affixed the die trial that matches with the bottom surface of keeper plate of steel on base is installed with pressure and distortion display box on another column.
When being mainly used in the pouring asphalt concrete moulding, the present invention applies corresponding pressure on test specimen top, to satisfy the requirement of the required pressure of different specimen moldings and porosity.The technical essential of this device has four aspects: the one, by rotary handle, drive screw mandrel, by pressing plate with pressure-acting the specimen surface in die trial; The 2nd, utilize and read corresponding force value at the pressure transducer that is arranged on device, adjust pressure to required scope by the rotary handle of rotational forming device; Simultaneously, by deformation-sensor adjust pressing plate to shift value, precision can reach 0.1mm; The 3rd, pressure plate structure is detachable, can according to the size of die trial diameter, change the pressing plate of different-diameter by pin; The 4th, die trial is fixed by the screw of bottom, avoids occurring running the mould phenomenon.By using this shaped device, can guarantee that the porosity of the hydraulic asphalt concrete test specimen of same batch of moulding in testing laboratory substantially is consistent and meets design requirement and construction requirement, for engineering provides reliable mixture ratio of asphalt concrete.
The present invention is rational in infrastructure, and is simple to operate, and convenient reading has improved the accuracy of indoor pouring asphalt concrete test index, for construction provides science, foundation accurately.。
Description of drawings
The invention will be further described below in conjunction with accompanying drawing, and Fig. 1 is structural representation of the present invention.
 
Embodiment
A kind of pouring asphalt concrete multifunction test and shaped device, as shown in Figure 1, affixed column 8 on base 10, affixed the back up pad 3 in the upper end of column 8, coordinate in the screw that upper backup pad 3 arranges and top is installed with the screw mandrel 1 of rotary handle 2, screw mandrel 1 end that is positioned at upper backup pad 3 belows is installed with pressure transducer 13, affixed the keeper plate of steel 11 in the bottom of pressure transducer 13; The fixed support 7 of adjustable position is installed on column 8, deformation-sensor 5 its contacts that are fixedly mounted with on fixed support 7 match with the end face of keeper plate of steel 11, affixed the die trial 9 that matches with the bottom surface of keeper plate of steel 11 on base 10 is installed with pressure and distortion display box 12 on another column 8.End at screw mandrel 1 is connecting pressure transducer 13 by the upper retaining collar 4 of installing.Lower end at pressure transducer 13 is connecting the support column of keeper plate of steel 11 by the lower retaining collar 6 of installing.The structure of the hold-down support 7 of adjustable position is for arranging pole bracket on sliding base sleeve, be fixedly mounted with deformation-sensor 5 on pole bracket, sliding base sleeve and column 8 are movingly, in the screw that arranges, bolt is installed on the sliding seat jacket wall, by bolt, hold-down support 7 is located on column 8.
 
The concrete operation steps of the present invention is as follows:
1 by the test specimen density of calculating, and calculates the required Asphalt concrete mixing thing weight of bituminous concrete test specimen of required moulding, weighs up with electronic balance, is positioned in the die trial of moulding needs;
2. with the Asphalt concrete mixing thing surface evening in die trial, and with after carrying pulpboard and proposing bituminous grout, upper surface is put a circular paper, and rotary handle makes pressing plate gently be pressed on pitch mix surface; By porosity and the die trial diameter of designing requirement, calculate the height of the required test specimen of moulding respective aperture gap rate test specimen again.
3 this moments, with pressure transducer and the zero clearing of displacement transducer numerical value, then rotary handle, slowly exert pressure, make the pressing plate decline rate be controlled at per minute 10~20mm left and right, until after required displacement readings, stablized 3 minutes, can read force value this moment by pressure transducer, then rise lower platen, take out together with die trial and carry out maintenance, carry out as stated above the moulding of next test specimen, until all specimen moldings are complete.
4 carry out uniaxial compression equal pressure when test, first test specimen are placed under pressing plate, and rotary handle is to the test specimen surface, and the deformation-sensor position is regulated in contact gently this moment, and measuring staff is touched in the pressing plate upper surface, and with pressure and deformation-sensor reset (zero clearing); Then rotary handle load application, the speed of rotary handle can be regulated the speed of loading, can read corresponding force value and deformation values by display.
