Description
Technical field
The present invention relates to a kind of mensuration, detecting instrument, especially relating to a kind of water creep appearance for measuring low infiltration coefficient.
Background technology
At present, damage by water causes the major reason of China's Protective Measures of Bitumen Pavement Initial Damage, the permeability performance on road surface is the major criterion weighing pavement quality quality, infiltration coefficient is then the important parameter of reaction pavement seepage performance, and therefore the infiltration coefficient of Accurate Measurement bituminous pavement becomes very important for the control of construction quality.
According to existing specification, when using pavement seepage apparatus measures, the measuring accuracy of graduated cylinder is only 10 ml, and interpolation is larger.When infiltration coefficient is less, estimate parallax when reading because the water surface is wider more obvious on measurement result impact.The measuring accuracy of existing graduated cylinder is inadequate in a word.
Adopt existing specification " highway engineering pitch and Asphalt Mixture Experiment code JTG E20-2011 " (T0730-2011), adopt light pressure gimmick to help exhaust.In process of the test, this operation is inadequate to the control dynamics of bubble obviously, can not ensure to discharge bubble completely, and especially when infiltration coefficient is less, bubble is larger on net result impact.
First draw a circle along plastic ring inner side and outer side respectively with chalk when adopting existing specification " highway engineering pitch and Asphalt Mixture Experiment code JTG E20-2011 " (T0730-2011) to determine infiltration area, then blow the encapsulant of inner side off, finally need water creep appearance centering.Whole process is complicated and can not Measurement accuracy infiltration area.
Summary of the invention
For the defect existed in above-mentioned prior art or deficiency, provide a kind of novel high-precision and easy-operating water creep appearance.From accurately controlling infiltration area, improving graduated cylinder precision and optimize exhaust process three aspects, guarantee the water creep appearance for measuring low infiltration coefficient that test result is more true and reliable.
The object of the invention is to realize by the following technical solutions:
For measuring the water creep appearance of low infiltration coefficient, comprise graduated cylinder, valve, it is to be linked into an integrated entity by some columns between the top board that is parallel to each other and base, and base is connected through connecting leg with in the middle part of top board, is also provided with the hollow cylinder graduated cylinder of upper and lower opening in the middle part of top board; This graduated cylinder is with connecting leg concentric and communicate, and described connecting leg adapting position is from top to bottom respectively equipped with valve and exhaust apparatus; Described base is circular, tapered to bottom margin cross section from connecting leg bottom it, and the bottom margin of base is protruding ringwise, and the infiltration area standard ring matched with its bottom margin is inserted in base bottom.
Described base upper end is also provided with ballast steel ring.
Described exhaust apparatus is provided with the hollow L shape bend pipe of closing cap by upper end, and in the middle part of closing cap, be provided with vent port formation, be provided with hollow closed cylinder float in the longitudinal pipe of described L shape bend pipe, this buoy top center is provided with minute hand, and the top of minute hand leans out described vent port; Its root is provided with the rubber blanket being greater than vent port.
Described L shape bend pipe, is set to 90 degree between its two pipe.
Described L shape bend pipe is made of copper.
Described float is that stainless steel is made.
The adapting position on described graduated cylinder top is provided with spillway hole, and this graduated cylinder is made up of transparent organic glass.
Described graduated cylinder, is provided with the scale mark from 100ml to 500ml from top to bottom.
Described taper, its inclined-plane and horizontal plane angle are 30 degree.
The height of described annular protrusion is at least 20 mm, and width is at least 30 mm.
Owing to adopting said structure, the present invention compared with prior art has following advantageous effect: manual vent bubble in water test process is become Automatic-exhausting pickle by the present invention, not only simplify operation steps and can ensure that bubble is discharged completely, especially when infiltration coefficient is less, Precise control advantage is more obvious.Present invention employs infiltration area standard ring, the water creep appearance quality in the more former code of this standard ring reduces a lot, can be simply light can accomplish macroscopic examination with tested point centering.If there is encapsulant can also directly strike off in infiltration area standard ring, control infiltration area simply exactly.The present invention not only easy and simple to handle, test accurately and also lower being convenient to of cost promote the use of when testing and scientific research detects.
Principle of work of the present invention compared with prior art has following characteristics:
(1) improve graduated cylinder precision
The graduated cylinder measuring accuracy of conventional water creep appearance is only 10 ml, and interpolation is larger.Parallax when reading is estimated comparatively large because graduated cylinder cross section is wider, therefore more obvious on low infiltration coefficient measurement result impact, cause the measuring accuracy of existing graduated cylinder inadequate.The graduated cylinder height that the present invention uses is 500 mm, and the scale of graduated cylinder can be made to become more meticulous, and final control survey precision is 2 ml, guarantees that test result is more accurate.
(2) exhaust process is optimized
Whether first test waits ultra-thin stainless steel hollow cylinder float in blister copper system 90 ° of bend pipes, observe float and can normally rise.Thread connecting mode is adopted to be arranged in the middle part of this water creep appearance base after confirming normal work.Before the water surface arrives bend pipe, float is static, and bubble is along exhaust apparatus Natural excrement; Slowly raise along with the water surface continues rising float, when vent port blocked by rubber blanket, automatically prevent the outflow of water, be located at after the infiltration area standard ring water instrument that oozes base bottom and base form closed system, gas is discharged along exhaust apparatus in base cavity pocket simultaneously.Gas in the present invention is discharged completely.This process is without the need to manual operation, simple.
(3) infiltration area is accurately controlled
Former Normalization rule water creep appearance and tested point centering, water creep appearance weight is very much not easy to operate, after centering by encapsulant affect can not macroscopic examination final whether entirely on the center.The present invention also bonding firmly with glass putty with tested point centering for infiltration area standard ring, its outer shroud smear encapsulant equally to lay base of the present invention, makes the present invention and road surface form closed system after determining water penetration test tested point.Water creep appearance quality in infiltration area standard ring more former code reduces a lot, can be simply light can accomplish macroscopic examination with tested point centering.If there is encapsulant can also directly strike off in infiltration area standard ring, control infiltration area simply exactly.
