Description
Technical field
The utility model belongs to the proving installation technical field, specifically relates to a kind of permeability rate proving installation for test pervious concrete pavement permeability rate.
Background technology
Pervious concrete is called again cellular concrete, permeable terrace, it is a kind of porous light concrete that is formed by aggregate, cement and the water system of mixing, it does not contain fine aggregate, mutually bond and form the equally distributed cellular structure in hole by coarse aggregate surface coating skim grout, therefore have ventilative, permeable and lightweight characteristics, also can be described as the draining concrete.Pervious concrete is by under the rainwater inflow place, effective recharge of groundwater, and the underground water table of alleviating the city sharply descend some Urban Environmental Problems of degradation, simultaneously, is the good pavement material of conservation of nature, maintaining ecological balance, energy alleviating urban heat island effect.But in prior art, the pervious concrete pavement of laying is not carried out the device of on-the-spot test permeability rate test, that is to say, the permeability rate of the pervious concrete pavement after laying is difficult to learn.
The utility model content
Technical problem to be solved in the utility model just is to provide a kind of permeability rate proving installation that can more accurately test the permeability rate of the pervious concrete pavement after laying.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the permeability rate proving installation, it is characterized in that: comprise base, described base end face is provided with the enlarging groove, described base top vertically arranges a graduated cylinder, and a rising pipe vertically is set below described graduated cylinder, described rising pipe upper end and graduated cylinder bottom connection, described rising pipe lower end and the top connection of enlarging groove, described rising pipe is provided with valve.
Preferably, described graduated cylinder bottom is arranged on a horizontal supporting plate, described back up pad is connected with base by four support bars that vertically arrange, on described back up pad, planar central is provided with a groove, described graduated cylinder bottom is plugged in described groove, described graduated cylinder bottom centre is provided with the first through hole, and described bottom portion of groove center is provided with the second through hole, and described rising pipe upper end open and the second through hole and the first through hole are communicated with.
Preferably, be provided with O-ring seal between described graduated cylinder bottom and back up pad.
Preferably, described base central upper portion is provided with vertical third through-hole, described third through-hole and rising pipe lower end and the top connection of enlarging groove,
Preferably, the diameter of described third through-hole is not less than 7mm.
Preferably, described enlarging groove is cone tank.
Preferably, described graduated cylinder upper end is provided with pressurizing valve and tensimeter.
Preferably, described base end face is connected by fluid sealant with pervious concrete pavement to be tested.
After adopting above structure, permeability rate proving installation of the present utility model compared with prior art has the following advantages:
because the utility model permeability rate proving installation is tested by the pervious concrete pavement of selecting certain area, possessed the on-the-spot test function, after valve open, water column in graduated cylinder is by the first through hole, the second through hole, rising pipe, contact and see through pervious concrete with pervious concrete after third through-hole and cone tank, described cone tank structure can make water column flow to pervious concrete pavement along the cone tank side face, water colunm height in graduated cylinder reduces, can more accurately calculate the permeability rate of the pervious concrete pavement after laying by recording water column falling head in graduated cylinder and required time.
