Technical field
The present invention relates to a kind of permeameter, refer in particular to be applied to concrete test block side sealing permeability test.
Background technology
Concrete is the great invention of Human Architecture industry.The invention of Portland cement（1824）It is existing more than 190 years away from the present
History, in this is more than 190 years, concrete has played important impetus to social development and human civilization.Permeability is
Determine a key factor of concrete durability, it is however generally that, its durability of the low concrete of permeability is also relatively good.Coagulation
Soil permeability refers to that liquid, gas or ion are stressed, the infiltration in concrete of chemical potential or electric field action, diffusion or migrate
Complexity.The permeability of concrete is directly related with density.Density is an important indicator of concrete, except influence
Outside permeability, the excellent of the indexs such as frost resistance, anti-carbonation aggressivity, precenting chlorate corrosion and the wear resistence of concrete is also determined
It is bad.So measurement permeability can be indirectly to concrete combination property evaluate.
Concrete impervious instrument is designed according to hydraulic principle, is pressed with motor run water pump, by pipeline with
Pressure vessel, controls the connections such as valve, die trial seat.Pressure enters pressure vessel by water pump output, is then delivered to sample system and enters
Row load test.Electro connecting pressure gauge and electric control system are housed, by the electric contact in electro connecting pressure gauge in pipeline
Regulation can make the pressure constant pressure experiment is carried out in prescribed limit.
Traditional concrete impervious instrument when water under high pressure permeability test is carried out, it is necessary to by concrete test block by sealing with wax or
Other encapsulants are pasted, prevents water under high pressure from being permeated from test specimen side.Traditional testing stand is generally higher, it is necessary to concrete is tried
Part is transported on testing stand carries out fastener connection again.Substantial amounts of test specimen needs to consume substantial amounts of manpower and time, operating efficiency
It is low.

Mouthful upper cover plate, be fixed on housing and the lock ring of upper cover plate can be locked, be fixedly connected on the lower cover of housing lower port and close
Back cover seat, and laid along inner walls and form the sealing shroud in relative closure space；The lower cover and sealed base
On be correspondingly provided with the high pressure mouth of a river；The top of the upper cover plate or housing is provided with sensor.
In a further embodiment, it is provided with sealing ring between the lower cover and sealed base.The housing upper end
The edge of mouth and lower port has seal groove.The housing cavity is circular platform type, 15 ° of outside withdrawing pattern at lumen openings.It is described close
Seal is O-ring seal, and the sealing shroud is silicone rubber seal set.The upper cover plate have a turning arm, the housing it is upper
Portion has plate of picking up the ears, and the turning arm is rotated with plate of picking up the ears and is connected.There is breach, the lock ring can be clamped on the turning arm
In the breach.
Compared with prior art, the present invention has advantages below：The permeameter is single specimen test device, by mixed
Solidifying soil test specimen is directly placed into housing cavity, pulls upper cover plate handle and with lock ring clamping handle first half of the month type groove, easily quick；
High-pressure hydraulic pump permeates bottom-up from lower shoe water filling, current along housing cavity, and sealing ring can use O-ring, can prevent height
Pressure water is revealed from base plate and firm banking junction, and sealing shroud is close to its side due to test block expansion, without traditional wax one by one
Encapsulation method, experiment shows that the sealing effectiveness of permeameter seals grade up to IP65.
