Wherein, a surface of at least one of the top base material 110 and described lower part base material 120 forms fluted, the top
Base material 110 is mutually relatively engaged with the lower part base material 120, and the groove is arranged at 110 He of top base material
To form the infiltration space 140 that junction is sealed between the lower part base material 120, when simulating infiltration, water is from the infiltration
Water hole 111 flows into, and oozes out after flowing through the infiltration space 140 from the profiling hole 121.
As shown in Figure 1, the utility model preferably be respectively formed in top base material 110 and lower part base material 120 it is fluted, more
The recess width or diameter preferably formed on lower part base material 120 is bigger than the groove formed on top base material 110.Thus, it is possible to make
Overflow groove 141 as shown in Figure 1 is formed, so that the water product under seeping is in this position.
Show a case that all to be formed on top base material 110 and lower part base material 120 in Fig. 1 it is fluted, in the utility model
In, the purpose that groove is formed on top base material 110 and/or lower part base material 120 is after engaging top base material and lower part base material
Closed infiltration space 140 is formed in-between, therefore, is formed in any one of top base material 110 and lower part base material 120
Groove, and make the two engagement that can also reach purpose of utility model, therefore belong to the scope of the utility model.
Through the above structure, when filling being easily positioned on top base material 110 of water, and water container and top base material are sealed
Between contact position when, hydraulic pressure is applied on top base material 110 and water seepage hole 111, so water under water seepage hole infiltration to infiltration

One or more water seepage holes can be blocked when use as needed, and only allow water from the infiltration of the pore size of satisfactory quantity
It is flowed through in water hole, so as to expand the scope of application of standard analog device.
The aperture of water seepage hole and deflector hole should not be too large, if its aperture is too big, by what is seeped water with road surface and road structure
Actual conditions are not inconsistent, therefore the aperture of deflector hole and water seepage hole is preferably not greater than 1.5mm.Profiling hole is under simulation water droplet
Hole, user simulate water and will lead to water product in simulation road structure if profiling hole is too small by the state being discharged after road structure
Infiltration space in, if its aperture is too big, water will easily flow out, thus be unable to accurate simulation infiltration process, therefore imitative
The aperture in shape hole is preferably 1-1.5mm.
As shown in figure 4, Fig. 4 (a) shows the working face of standard analog device, that is, it is formed with the top base material of water seepage hole
Upper side, Fig. 4 (b) shows the seepage surface of standard analog device, that is, is formed with the bottom surfaces of the lower part base material of profiling hole.
