Abstract
The utility model discloses a simple and portable permeation coefficient tester which comprises a water supply system, an overflow hole and a tester body. The tester body is a cover-free container made of transparent materials. Volume scale marks are arranged on the side surface of the container. The overflow hole is formed above the scale marks of the tester body. The water supply system is connected with the open end at the top of the tester body. The tester body is made of PMMA organic glass. The simple and portable permeation coefficient tester is simple in principle, convenient to operate and carry, capable of testing a fixed water level permeation coefficient, capable of testing a variable water level permeation coefficient and simple in calculation, and brings great convenience to permeation coefficient testing in the construction site.
Description
Technical field
The utility model relates to the Simple portable instrument for measuring permeability coefficient, belongs to field of mechanical technique.
Background technology
What traditional pavement structure adopted is fluid-tight pavement structure, and namely surface layer and basic unit adopt close material to carry out making, guarantees that infiltration can not penetrate in the roadbed under the road surface.But the waterproof pavement discharge capacity is limited, easily causes road surface ponding on a large scale, causes obstruction to traffic and traffic hazard, causes the city waterlogging, and underground water can not get easily causing land subsidence under the prerequisite of effectively replenishing.Rainwater is drained very soon or is evaporated, and makes the city raised dust pollution grows worse, and the ground medial temperature raises, and accelerates the appearance of " urban heat land effect ".And pervious concrete pavement has the advantages such as environmental protection, driving safety; at present; this technology is subject to the extensive concern of society day by day; and be acknowledged as a kind of urban road paving structure pattern of human kind sustainable development; can effectively increase permeable, the ventilation space in city, improve the ecologic environment in city.
Coefficient of permeability is the important indicator that characterizes the pervious concrete water permeability, at present domestic method of testing about appendix A coefficient of permeability among the measurement Main Basis CJJ/T 135-2009 " water-permeable cement concrete pavement technique rules " of permeation coefficient of permeable concrete, although the method can obtain test findings comparatively accurately, but measurement mechanism is complicated, not portable, be not suitable for the working-yard operation.
The utility model content
The utility model provides the Simple portable instrument for measuring permeability coefficient, can overcome above technological deficiency, can either reach the purpose of test concrete permeable performance, and is simple in structure, easy to operate, is easy to carry.
For solving above technical matters, the utility model provides following technical scheme: a kind of Simple portable instrument for measuring permeability coefficient, described analyzer comprises water system, spout hole, analyzer main body, and described analyzer main body is the non-covered container of a transparent material, and the vessel side surface has the volume scale; The scale top of described analyzer main body has spout hole; Described water system connects analyzer main body open top end.
Further, described analyzer material of main part is the PMMA organic glass.
Further, described overflow orifice diameter is 10mm.
Further, two of described analyzer main body sides all have scale.
This Simple portable instrument for measuring permeability coefficient that the utility model relates to, principle is simple, and is easy to operate, be easy to carry, not only can measure and decide the water level coefficient of permeability but also can measure to become the water level coefficient of permeability, and calculate simply, the coefficient of permeability of measurement carry out to(for) the working-yard has very large convenience.
Description of drawings
Fig. 1 is the utility model Simple portable instrument for measuring permeability coefficient structural representation.
Embodiment
As shown in Figure 1, analyzer comprises water system 1, spout hole 2, analyzer main body 3, the analyzer main body 3 inner pervious concrete test specimens 4 of placing, in order to measure the water permeability of pervious concrete test specimen 4 forming directions, encapsulation process is carried out with wax in side around the pervious concrete test specimen 4, be connected with analyzer main body 3 again, and with the wax place that is tightly connected, guarantee that the water in the device passes through along the intercommunicating pore of pervious concrete test specimen 4 inside, in analyzer main body 3, add water to spout hole 2 interior outflows, the time t when the mensuration water level is down to 300 mm from 350mm
1Be down to the time t in when surface time from 350mm with water level
2, calculate according to following formula.
The computing formula of coefficient of permeability is:
In the formula, ν---coefficient of permeability (mm/s);
H---water level falling head (mm);
The time s of experience when the t---water level descends.
ν wherein
1For deciding water level coefficient of permeability and ν
2For becoming the water level coefficient of permeability, according to CJJ/T 135-2009 " water-permeable cement concrete pavement technique rules " permeation coefficient of permeable concretes (15 ℃) 〉=0.5mm/s.Generally we are with ν
2Measurement result be test findings.
Embodiment described in the utility model does not consist of the restriction to the application's scope; every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
