Improve sealing effectiveness.
With reference to figure 1 and Fig. 5, to apperance 1 inside add the concrete to stir, consolidation simultaneously scrapes off unnecessary concrete,
After concrete hardening reaches some strength, apperance of dismantling 1 forms concrete sample 4, and now some baffle rings 3 try with concrete
Sample 4 is fixed together to form entirety.Concrete sample 4 is put into curing box together with baffle ring 3 and conserved.With reference to Fig. 6, need
When wanting impervious detection, reload in apperance 1, then apperance 1 is fixed on monitor station 5, mould after concrete sample 4 is taken out
The contact surface of sample 1 and monitor station 5 is provided with the rubber ring of " O " shape, to prevent water under high pressure leaks from there from causing the failure of an experiment.Detection
Platform 5 is made using stainless steel plate, and apopore 51 is provided with the center of monitor station 5, and apopore 51 passes through flexible pipe and outside high pressure
Water pump connects, and is tested to flow out water under high pressure.
The concrete impermeability test is as follows with mold use method：
S1：Assemble apperance 1：Sealing ring 1 is placed into the groove 15 of two pieces of templates 10 and causes sealing ring 1
Both ends it is concordant with the both ends of groove 15.Then some baffle rings 3 are sequentially inserted on the groove 15 of one of template 10, made
Obtain baffle ring 3 to be clamped by the two panels sealing ring 1 in groove 15, then another piece of template 10 is alignd with this template 10, due to close
There is enlarging 1511 inner side of seal 1 so that the projection 32 of baffle ring 3 can easily slide into two panels sealing ring 1 it
Between, it is adjacent to each other then firmly to push two pieces of templates 10 so that card article 12 is snapped onto in neck 13, then is coordinated with bolt 1
Nut fastens two pieces of templates 10, and apperance 1 is completed.
S2：Sample preparation and maintenance：Apperance 1 is fixed on sample preparation platform 2 by bolt 2 142, it is equal that stirring is added into apperance 1
Even concrete, consolidation scrape off unnecessary concrete after filling up, demounting bolt 1 and spiral shell after concrete reaches some strength
Bolt 2 142, template 10 is pulled open to both sides, baffle ring 3 takes sealing ring 1 out of, sealing ring 1 is picked up be filled into again it is recessed
In groove 15, concrete sample 4 is put into curing box together with baffle ring 3 and conserved.
S3：Impervious detection：Concrete sample 4 is taken out, two pieces of templates 10 are re-assemblied in the periphery of concrete sample 4,
Apperance 1 and concrete sample 4 are fixed on monitor station 5, tested according to code requirement.
Due to the effect of baffle ring 3 so that High-Pressure Water is formed in concrete sample 4 with the seam crossing of apperance 1 to stream, compared to
Extend from the path that concrete sample 4 penetrates through, therefore reduce the possibility of the failure of an experiment.Baffle ring 3 interlocks with template 10
Position-limiting action is played to concrete sample 4, prevents concrete sample 4 from being relatively moved in the presence of High-Pressure Water with apperance 1.This
Outside, substitute wax of the prior art or grease seal with the mode of streaming, keep the integrality of sample.
Embodiment two：
A kind of concrete impermeability test mould, as shown in figs. 4 and 7, it is with the difference of embodiment one with sealing
Enclose 2 152 and instead of the single sealing ring 1 of two panels in groove 15, be i.e. the rubber in the outside of holding tank 1512 stretches out simultaneously
It is connected as a single entity.When sealing ring 2 152 is taken out of by baffle ring 3, enlarging 1511 is flared out with hand, sealing ring 2 152 from baffle ring 3
On remove and reload again in groove 15.It is that the installation number of sealing ring 2 152 is few compared to the advantage of embodiment one, pacifies
Dress is more convenient.
Embodiment three：
A kind of concrete impermeability test mould, as shown in Figure 7 and Figure 8, it is that use is close with the difference of embodiment two
Seal 3 153 instead of sealing ring 2 152, and sealing ring 3 153 is solid semicircular rings.The inner circle of sealing ring 3 153 is set
There is wide-mouth groove 1531, outer circumference surface is adhesively fixed with groove 15, and wide-mouth groove 1531 is brought into close contact with the projection 31 on baffle ring 3 to rise
To sealing function.It is compared to the advantage of embodiment two, sealing ring 3 153 will not be taken out of by baffle ring 3 when dismantling template 10, it is not necessary to
Sealing ring 3 153 is laid again, further reduces operation difficulty.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
