In order to solve above technical matters, the utility model is provided for the specimen molding device of pervious concrete, comprise base plate, static pressure force application apparatus and die trial, described static pressure force application apparatus is fixed on base plate rotatably, and be pressed in die trial, described die trial is positioned on base plate, and described static pressure force application apparatus comprises runing rest, lever, slide bar and slide bar stop means; Described lever one end is connected on runing rest in relative rotation, runing rest can rotate around axis and be fixed on base plate, described lever suppressing action is in the top of slide bar, and described slide bar can be slided up and down by slide bar stop means, and the other end of slide bar is equipped with hammer; Described die trial is provided with volume capacity sleeve, described hammer applies pressure to the surface of described volume capacity sleeve.
Being further defined to of technical solutions of the utility model, described slide bar stop means comprises sliding rod rack, and one end of described sliding rod rack is fixed on runing rest, and the other end of sliding rod rack has slide opening, and described slide bar is installed in this slide opening; Described slide bar upper-end part of driving has roller groove, and described roller is fixed in roller groove rotatably, and lever is pressed on the roller in the roller groove of slide bar upper end.
Being further defined to of technical solutions of the utility model, slide bar is provided with the adjustable limit circle that restriction presses down height; Described spacing collar is positioned at above sliding rod rack, and and is provided with spring between slide opening.
Being further defined to of technical solutions of the utility model, described base plate is fixed with rack sleeve, and described runing rest is installed on the rack sleeve on base plate, and runing rest can be made to rotate freely.
Being further defined to of technical solutions of the utility model, described hammer termination is square.
The beneficial effects of the utility model are: the utility model, by applying the mode of static pressure to pervious concrete, avoids pervious concrete vibrated and the situation of stream slurry.Apply downward pressure by static pressure force application apparatus to hammer, according to the strength that road pavement pressure during mechanical execution presses down with the static pressure force application apparatus estimated, calculate the size on square hammer top, warranty test room condition of molding is consistent with construction condition.Controlling test specimen unit weight by adding cover volume capacity sleeve in die trial, by controlling the unit weight of pervious concrete test specimen, carrying out the accuracy of the related data such as proof strength and coefficient of permeability.By above-mentioned technical scheme, the pervious concrete test piece intensity that testing laboratory is shaping and water permeability press close to the actual conditions of working-yard, and test figure has certain representativeness, are conducive to the quality control of engineering staff to pervious concrete.The device avoids some disadvantages of existing molding mode, mixture does not flow slurry blocking hole, and consolidation effect is good, and data are reliable, substantially increases indoor shaping work efficiency.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
For the specimen molding device of pervious concrete, comprise base plate, static pressure force application apparatus and die trial, described static pressure force application apparatus is fixed on base plate rotatably, and be pressed in die trial, described die trial is positioned on base plate, have hammer 6 in the end of static pressure force application apparatus, described die trial is provided with volume capacity sleeve 7, the hammer 6 of described static pressure force application apparatus end is pressed on the surface of the volume capacity sleeve 7 in described die trial.
As shown in Figure 1, described static pressure force application apparatus comprise runing rest 1, lever 2 and slide bar and with slide bar stop means; Described lever 2 one end is connected on runing rest 1 in relative rotation, runing rest 1 can rotate around axis and be fixed on base plate, scheme in the present embodiment is: base plate is fixed with rack sleeve, described runing rest 1 is installed on the rack sleeve on base plate, and runing rest 1 can be made to rotate freely.Described slide bar upper end has roller groove, and described roller 3 is installed in roller groove rotatably, on the roller 3 of lever 2 suppressing action in the roller groove of slide bar upper end.Namely described lever 2 is pressed on the top of slide bar.Described lever 2 contacts the roller fulcrum of slide bar upper end, and when lever 2 is stressed, down-pressure roller fulcrum band moving slide-bar is downward, and roller fulcrum rolls and ensures that lever 2 can move.It is free to rotate when described roller 3 acts on by lever 2.Described slide bar can be slided up and down by slide bar stop means, described slide bar stop means comprises sliding rod rack, and one end of described sliding rod rack is fixed on runing rest 1, and the other end of sliding rod rack is provided with slide opening, described slide bar is installed in slide opening, and slide bar can only move up and down in slide opening; The top being placed on described slide opening place at slide bar is provided with the adjustable limit circle 4 that restriction presses down height; Between described spacing collar 4 and slide opening, spring 5 is installed, makes to press down rear slide bar and automatically to rebound original position.The other end of slide bar is equipped with hammer 6.The shape of described hammer 6 as shown in Figure 2.Described hammer 6 termination is square.When depress lever 2 until reach after spacing collar 4 position cannot press down again, now square hammer 6 depressed position that connects of slide bar lower end is just concordant with die trial upper surface; Described volume capacity sleeve 7 can be arranged on die trial top, and its volume size calculates according to the coefficient of loose laying required during construction, controls test specimen unit weight.The structure of described volume capacity sleeve 7 as shown in Figure 3.
