Description

The permeable bulk coefficient of permeability of vacuum detector

Affiliated technical field

Present patent application belongs to the engineering Inspection Technique field.

Background technology

The present situation urban road belongs to waterproof pavement basically, and the characteristics of waterproof pavement are to stop under the precipitation to ooze.Along with Chinese economic development, the porous pavement of environmental protection becomes the trend of development in the future, and may all replace waterproof pavement.Therefore the permeable bulk relevant with porous pavement can be widely used in the engineering.And the most important mass parameter of permeable bulk is its coefficient of permeability, and respective standard is People's Republic of China's building material industry standard (JC/T945-2005).But the present domestic corresponding permeable bulk coefficient of permeability detector that also do not have.

The coefficient of permeability measuring principle that industry standard provides is as follows:

Testing requirements can be loaded sample and keep the test unit of the above vacuum tightness of 90kPa.Test water is used air free water, can adopt freshly prepd distilled water, otherwise should before test, carry out pump-down process to all distilled water, being about to water packs in the water container, make it place vacuum extractor, slowly be evacuated to the vacuum tightness of 90kPa, till no bubble is emerged in aspirator bottle, stand-by after the distilled water exhaust.

Test procedure:

With the diameter (D) and the thickness (L) of steel ruler measurement cylinder sample, measure twice respectively, average, be accurate to 0.1cm, calculate the upper surface area (A) of sample.

With around the sample with encapsulant or alternate manner good seal, make it water-tight, water is only from the infiltration of the upper and lower surface of sample.

After the material cured to be sealed, sample is put into vacuum plant, be evacuated to 90kPa ± 1kPa, and keep 30min.When keeping vacuum, adding enough water covers sample and makes water level exceed sample 10cm, stop to vacuumize, soak 20min, with its taking-up, the coefficient of permeability device of packing into is placed on support (19) with sample and goes up and be connected good seal with permeable cylinder (23), puts into overflow tank (18), open water supply valve, supply water by water system (16), air free water is entered in the container, the overflow vent (17) that waits overflow tank (18) is when there are flowing out, adjust inflow, make permeable cylinder (23) keep certain water level, about 150cm, the overflow vent (17) for the treatment of the overflow vent of overflow tank (18) and permeable cylinder (23) flow out after the water yield stablizes, with graduated cylinder (21) from the water delivering orifice water receiving, write down and flowed out the water yield (Q) in five minutes, measure three times, average.

Measure the water level of permeable tube (23) and the difference H (22) of overflow tank water level with steel ruler, be accurate to 0.1cm.

Temperature (T) with overflow tank water in the thermometer measure test is accurate to 0.5 ℃.

The technical matters of testing main existence with this principle, method has:

1, because sample is a porous structure, the sample side seal adopts the paraffin method of soaking more, and whiteruss immerses sample easily and blocks permeable hole and influence test findings and precision; Upper surface is because the uneven very difficult sealing of permeable block itself.Make the sealing out-of-shape, surperficial water permeable area is difficult to accurate measurement.Seal sample is more time-consuming, and is difficult to ensure the quality of products.

2, to put into the vacuum plant purpose should be to extract the permeable block bubble out to sample, forms negative pressure.Add when being higher than specimen surface 10cm vacuum water and stop to vacuumize, purpose is by atmospheric pressure hydraulic pressure to be gone in the sample, prevent since in the sample bubble have that current pass through when hindering test, influence test findings.Soak take out that sample is put into the vacuum plant process behind the 20min since sample this as permeable porous structure, the water that is full of in the sample aperture flows out under action of gravity in this course, sample part hole can be full of by air again, influence vacuum immersion effect.

When 3, measuring poor (H) of permeable cylinder water level and tank water level with steel ruler, method simple result error is big.

4, since in the vacuum plant water after soaking sample, must empty when soaking next sample again, and the coefficient of permeability test unit also to be reentered into vacuum water, causes the vacuum water waste.

Summary of the invention

Purpose of the present invention is exactly at above-mentioned technical matters, the permeable bulk coefficient of permeability of a kind of vacuum detector of inventing in order accurately to measure permeable bulk coefficient of permeability.

Its main technical schemes is as follows:

The permeable bulk coefficient of permeability of a kind of vacuum detector, it is characterized in that, this detector is made up of permeable bulk die trial, sealing shroud, overflow vacuum plant and permeable cylinder, sealing cover (2) comprises upper testing mould (1) and lower testing mould (3), upper and lower die trial is by screw rod and bolted on connection, and sealing shroud (2) places between the upper and lower die trial; Overflow vacuum plant (5) comprises the overflow vacuum plant lid (4) at vacuum overflow water drum (6) and its top, have overflow vent (7) on vacuum overflow water drum (6) sidewall, have aspirating hole (8) and inlet opening (9) on the overflow vacuum plant lid (4), vacuum overflow water drum (6) and overflow vacuum plant lid (4) pass through bolted on connection; Permeable cylinder (10) stack shell has an overflow vent (11) by last position.

Described sealing shroud (2) is a cylindrical shape, and the sealing shroud material is a rubber.

On the bottom in the described vacuum overflow water drum (6) support (12) is housed.

The water inlet of vacuum overflow mechanism lid (4) is inserted with a water inlet pipe (13), and water inlet pipe is passed into vacuum overflow water tube bottom.

The stack shell of vacuum overflow water drum (6) is carved with the high scale of energy measurement water level outward.

The stack shell of permeable cylinder (10) is carved with the high scale of energy measurement water level outward.

The overflow vent (7) of described vacuum overflow water drum is furnished with the sealing cap (14) of bolt.

Packing washer (15) is arranged between the described upper and lower die trial.

The beneficial effect that adopts above technical scheme to reach is:

1, adopt special sealing shroud that sample is carried out side seal, sealing shroud itself belongs to rubber epistasis structure, can guarantee the sealing effectiveness that the sample side is good.Sealing shroud is originally as the forming machine converted products, and quality is guaranteed, and the sealing ring mouth is a standard circular, guarantees that sample upper surface water permeable area is accurately stable.

2, coefficient of permeability and vacuum extractor unite two into one, and can omit the sample process of taking out, and improve to vacuumize effect and soak effect.Finish permeable cylinder and be connected with die trial in water, the short form test process is increased work efficiency and test accuracy.

3, permeable cylinder itself is with scale, can accurately measure poor (H) of permeable cylinder water level and tank water level, and method is simple, the precision height.

4, each vacuum utensil itself has transparent organic glass view window and scale, the convenient observation and control test overall process.

5, the whole test device is simple to operation, and security and robotization performance are all higher.

The present invention compares with classic method, installs reasonable in design, easy to use.The precision of warranty test is more suitable for permeable bulk coefficient of permeability and detects preferably.
