Background technology
The cracking of concrete has exceeded tensile strength mainly due to tension in concrete, or because elongation strain reaches
Or exceed caused by limit stretch value.Its origin cause of formation is sufficiently complex, from internal cause, have raw material are bad, uniformity is bad,
Match ratio is not excellent, the deformation of heat of hydration temperature, own vol and its calorifics, mechanical property do not reach the requirement of anti-crack ability；There is structure
Form is unreasonable, easily causes excessive stress concentration；Parting, piecemeal are incorrect, it is difficult to bear the shadow of external condition and load
Ring etc..From external cause, there are the environmental changes such as temperature, humidity, have basis, the constraint of old concrete, there is basic differential settlement
With outer lotus overload etc..
For the crack occurred, more commonly used and ripe construction method has following four：1) surface preparation；2) fill out
Fill closely knit method；3) pressure grouting；4) structural strengthening method.Xtah Crude Clay structure causes of cracks is various, but facts have proved and take
The measure of stating can effectively prevent concrete structure crack, can obtain preferable Social benefit and economic benefit.
Therefore, research one kind goes for concrete compression under different size of concrete style, simulation reality
Compressive sealed property detection device and detection method after the repairing concrete crack of situation infiltration situation, there is important reality meaning
Justice.
The content of the invention

Compressive sealed property detection device after the repairing concrete crack of concrete compression situation infiltration situation under style, simulation reality
And detection method.
The present invention solves its technical problem and takes following technical scheme to realize：
Compressive sealed property detection device after a kind of repairing concrete crack, including balancing gate pit, shaping mould, supporting plate, institute
State shaping mould and be located at the supporting plate side, the supporting plate is provided with observation window, and the observation window size is more than described
Shaping mould size, the balancing gate pit are fixedly connected with the supporting plate, and the pressure chamber surface is provided with water filling port and pressure
Controller.
Further, the balancing gate pit is cylinder.
Compressive sealed property detection method, comprises the following steps after a kind of repairing concrete crack：
(1) get out suitable concrete first before experiment, take test specimen, and be put into shaping mould, it is ensured that sample
Product are laid flat with shaping mould lower baffle plate, are poured in sample and shaping mould gap and are prepared concrete in advance, treat that concrete is abundant
Solidification；
(2) water filling into balancing gate pit by water filling port, and by pressure controller control pressure, simulate and mixed under reality
Solidifying native compression situation infiltration situation, and can be observed at any time by observation window.
The advantages and positive effects of the present invention are：
The equipment of the present invention compensate for the vacancy of the not no kind equipment in conventional laboratory, and simple in construction, easy to operate,
Go for concrete compression situation infiltration situation under different size of concrete style, simulation reality, can be direct
Observe infiltration situation.
